 - Keep durable prompt admission separate from model execution. `SessionV2.prompt(...)` admits one durable `session_input` row before scheduling advisory `SessionExecution.wake(sessionID)` unless `resume: false` requests admit-only behavior. The serialized runner promotes admitted inputs into visible user messages at safe boundaries.
 - Reusing a Session ID adopts the existing Session. Reusing a prompt message ID reconciles an exact retry only when Session, prompt, and delivery mode match; conflicting reuse fails. Historical projected prompts lazily synthesize promoted inbox records during exact retry.

 ## Relationships
 
-- A **System Context** contains one or more **Context Components**.
-- A changed **Context Component** may produce one **Mid-Conversation System Message** containing its newly effective state.
-- A **Mid-Conversation System Message** persists its originating **Context Component** key and the exact rendered text sent to the model.
-- A **Context Checkpoint** advances atomically with the corresponding durable **Mid-Conversation System Message**.
-- A **Context Checkpoint** stores one rendered-content hash per stable **Context Component** key so core and plugin-defined components can evolve independently.
-- Changes from multiple **Context Components** admitted at one safe boundary combine into one **Mid-Conversation System Message**.
+- A **System Context** is an opaque carrier composed from zero or more **Context Sources**.
+- **Session History** contains projected conversational messages and admitted **Mid-Conversation System Messages**; the active **Baseline System Context** remains separate provider-request state.
+- The **System Context Registry** uses stable-keyed scoped contributions to assemble the current **System Context**; contributor removal naturally removes its sources at the next **Safe Provider-Turn Boundary**.
+- A changed **Context Source** may produce one **Mid-Conversation System Message** containing its newly effective state.
+- A **Mid-Conversation System Message** persists the exact combined rendered text sent to the model.
+- The current **Context Snapshot** advances atomically with the corresponding durable **Mid-Conversation System Message**.
+- A **Context Snapshot** stores one codec-encoded JSON value and, for removable dynamic sources, a pre-rendered removal message per stable **Context Source** key.
+- Changes from multiple **Context Sources** admitted at one safe boundary combine into one **Mid-Conversation System Message**.
 - Context changes are sampled and admitted lazily at a **Safe Provider-Turn Boundary**, never pushed asynchronously when their source changes.
 - At a **Safe Provider-Turn Boundary**, newly promoted user input or settled tool results precede any combined **Mid-Conversation System Message**.
-- The first provider turn renders the latest **Baseline System Context** and initializes its **Context Checkpoint** without emitting a redundant **Mid-Conversation System Message**.
-- Compaction starts a new **Context Epoch** with a freshly rendered **Baseline System Context** and **Context Checkpoint**; prior **Mid-Conversation System Messages** remain durable audit history but leave projected model history.
-- A **Context Checkpoint** is an evolvable component map; a newly registered core or plugin-defined **Context Component** absent from an existing checkpoint emits its current state once at the next **Safe Provider-Turn Boundary**.
-- **Context Component** keys are stable and namespaced; duplicate keys fail assembly. Built-in components preserve declaration order and plugin-defined components append in lexicographic key order so rendered context is deterministic.
-- Each **Context Component** loader returns its model-visible baseline string and absolute current-state update string from one coherent sample; the update string is hashed for change detection.
+- An **Admitted Prompt** is replayable pending input, not yet model-visible **Session History**.
+- **Prompt Promotion** atomically consumes the pending inbox entry and appends its model-visible user message.
+- Steering prompts promote at the next **Safe Provider-Turn Boundary** while the current **Session Drain** still requires continuation. Promoting any newly admitted user input resets the selected agent's provider-turn allowance; multiple prompts promoted at one boundary reset it once.
+- A queued prompt does not promote while the current **Session Drain** requires continuation. The runner promotes one queued prompt when the Session would otherwise become idle, then reevaluates continuation before promoting another.
+- A **Session Drain** is process-local coordination rather than a durable domain entity. Durable recovery must reason from prompts, projected history, provider attempts, and tool state rather than inventing an enclosing execution identity.
+- The first provider turn renders the latest complete **Baseline System Context** and initializes its **Context Snapshot** without emitting a redundant **Mid-Conversation System Message**; unavailable initial context blocks the turn instead of persisting an incomplete baseline.
+- Initial **System Context** preparation precedes the first durable input promotion so an unavailable baseline leaves that input pending and retryable; ordinary reconciliation remains after promotion.
+- Compaction starts a new **Context Epoch** with a freshly rendered **Baseline System Context** and **Context Snapshot**; prior **Mid-Conversation System Messages** remain durable audit history but leave projected model history.
+- A newly registered core or plugin-defined **Context Source** absent from the current snapshot emits its baseline rendering once at the next **Safe Provider-Turn Boundary**.
+- **Context Source** keys are stable and namespaced; duplicate keys fail composition. `SystemContext.combine(...)` preserves caller order; the **System Context Registry** evaluates producers concurrently and combines them in stable contribution-key order so rendered context remains deterministic.
+- Each **Context Source** loader returns one coherent typed value. `SystemContext.make(...)` hides that value type so differently typed sources compose uniformly. Its codec compares and stores that value; its pure renderers produce model-visible baseline, update, and removal text only when needed.
+- `SystemContext.initialize(...)` observes a composed **System Context** once and produces a fresh **Baseline System Context** with its **Context Snapshot**.
+- `SystemContext.reconcile(...)` observes a composed **System Context** once and returns exactly one next action: unchanged, updated, replacement ready, or replacement blocked.
+- `SystemContext.replace(...)` renders a fresh generation after completed compaction or another baseline-replacing transition; it reports replacement blocked while previously admitted context is unavailable.
 - **Unavailable Context** uses stale-while-revalidate semantics and is distinct from a successfully loaded absence, which may emit removal text.
-- Ordinary **Context Component** loaders return values directly; loaders that intentionally use stale-while-revalidate may explicitly return **Unavailable Context**.
-- Nested project instruction files discovered while reading join the effective instructions returned by the instruction service and are admitted durably at the next **Safe Provider-Turn Boundary**.
-- A discovered nested project instruction remains active for the session while it stays in the same location and is folded into later **Baseline System Contexts** after compaction.
+- Ordinary **Context Source** loaders return values directly; loaders that intentionally use stale-while-revalidate may explicitly return **Unavailable Context**.
+- Nested project instruction discovery after successful reads remains a follow-up; when implemented, discovered instructions must be admitted durably at the next **Safe Provider-Turn Boundary**.
 - Location-scoped services naturally re-resolve effective context when a moved session next runs in its destination location.
+- Moving a Session clears its active **Context Epoch**, so the destination must initialize a complete baseline before another prompt can promote.
 - Instruction discovery, source identity, persistence, and file loading belong to the instruction service; the **System Context** abstraction only composes effectful producers and renders loaded values.
-- Plugin-defined **Context Components** register through a scoped replayable registry so plugin hot reload adds and removes components predictably.
+- The first instruction-service slice observes global and upward project `AGENTS.md` files as one ordered aggregate **Context Source** at each **Safe Provider-Turn Boundary**.
+- Built-in and instruction context producers register through the **System Context Registry** with stable contribution keys. Plugin-defined context registration and hot-reload lifecycle remain a follow-up built on the same scoped registry seam.
+- Selected-agent available-skill guidance is a **Context Source** composed with Location-wide registry sources immediately before Context Epoch admission. It lists only names and descriptions permitted for that agent; skill bodies and locations are exposed only through the permission-checked `skill` tool.
+- The selected agent and model are sampled when a provider turn starts. Changes admitted after that boundary apply to the next provider turn and do not restart the current turn.
+- Selected-agent available-skill guidance remains a **Context Source**. An agent switch that changes that guidance produces a **Mid-Conversation System Message** while preserving the current baseline.
+- Local tool authorization and pending permission requests retain the effective agent of the provider turn that issued the call; a later agent switch cannot change that call's policy.
 - Context source changes never wake idle sessions; the next naturally scheduled **Safe Provider-Turn Boundary** loads and compares current values lazily.
 - Once admitted, a **Mid-Conversation System Message** remains durable even if the following provider attempt fails and is replayed unchanged on retry.
-- **Mid-Conversation System Messages** remain durable model-projection history but are hidden from normal user-facing transcript surfaces.
-- The date **Context Component** initially preserves host-local calendar-date behavior; a configured user timezone may replace that default later.
+- **Mid-Conversation System Messages** remain durable Session-message history; normal user-facing transcript surfaces may hide them.
+- The date **Context Source** initially preserves host-local calendar-date behavior; a configured user timezone may replace that default later.
 - A **Context Epoch** begins with one immutable **Baseline System Context**.
 - A **Baseline System Context** is stored durably and reused verbatim across process restarts within its **Context Epoch**.
-- A **Baseline System Context** durably preserves deterministic keyed top-level component strings rather than eagerly joining all text; request assembly lowers them into canonical LLM system parts.
-- Compaction or a model/provider switch starts a new **Context Epoch** because the baseline can be replaced without preserving the prior provider cache.
-- A model/provider switch always starts a new **Context Epoch** while preserving chronological conversation history.
+- A **Baseline System Context** durably preserves the exact joined text used for the active provider-cache prefix.
+- Completed compaction starts a new **Context Epoch** on the next provider attempt, folding the current complete **System Context** into a fresh baseline and removing earlier **Mid-Conversation System Messages** from active model history.
+- A model/provider switch preserves the current **Context Epoch** and chronological conversation history; the new selection applies to the next provider turn.
+- The **PTY Environment** is a server concern rather than a Core PTY concern. PTY creation merges caller values, then the host overlay, then Core-forced terminal invariants such as `TERM` and `OPENCODE_TERMINAL`.
+- Networked and **Embedded OpenCode** use the same **OpenCode Client** and preserve the full HTTP encoding, routing, middleware, and decoding boundary; only the `HttpClient` transport differs.
+- The Effect-native network constructor obtains `HttpClient.HttpClient` from its environment so callers own transport selection, recording, tracing, retries, and tests. Convenience runtimes may provide a fetch transport separately.
+- Creating **Embedded OpenCode** is scoped. Closing its owning Scope releases the in-process server resources, database resources, registrations, and fibers.
+- **Embedded OpenCode** exposes shared client capabilities and embedded-only capabilities on one object; consumers do not navigate through a nested `.client` property.
+- The beta **OpenCode Client** currently uses plural consumer-facing capability groups such as `sessions`; whether the stable Session namespace should instead be singular `session` must be settled before stabilization. Internal server identifiers do not implicitly define public client names.
+- Server's concrete `HttpApi` is authoritative for shared **OpenCode Client** capabilities. Codegen compiles its Session group directly; the Effect runtime uses an equivalent Protocol-only projection so generated artifacts remain independent of Core and Server.
+- SDK generation reflects the public `HttpApi` once into an **SDK Contract IR**. Promise and Effect emitters share endpoint structure and transport metadata without being required to expose identical public values: an emitter may select encoded wire types, decoded domain types, compile-time brands, runtime validation, and its own execution abstraction independently.
+- The first Effect emitter is the rich projection: it exposes decoded Effect-native values, preserves brands and schema transformations, performs runtime schema decoding, and delegates transport interpretation to `HttpApiClient`. Lighter wire-shaped Effect output remains possible through another emitter policy rather than constraining the shared IR.
+- The rich Effect emitter regenerates private executable schemas when the **SDK Contract IR** proves that their transport semantics can be reproduced exactly. Contracts with authoritative custom transformations use the import-based Effect emitter against a Protocol-only client projection whose generated transport output is tested against Server's concrete API; the Promise emitter still derives zero-Effect structural wire types from the same IR.
+- `@opencode-ai/protocol` owns Session endpoint construction and middleware placement. Server supplies concrete middleware keys to produce the authoritative build-time API; the client projection supplies transport-only keys without importing Core or Server at runtime.
+- The first Promise emitter targets the same clean domain-oriented method organization rather than Hey API source compatibility. It returns unwrapped values directly, rejects declared and infrastructure failures, and begins with minimal client-level transport configuration; result wrappers, interceptors, and legacy generated signatures are outside the initial surface.
+- The first Promise emitter parses response syntax and trusts its generated structural types; it does not perform runtime structural validation. Malformed payload syntax fails, while a syntactically valid shape mismatch is not detected at the SDK boundary. Standalone validator generation remains an optional future emitter policy.
+- Declared Promise-client failures retain their tagged structural wire values and have generated type guards. Consumers do not depend on generated `Error` subclass identity, preserving discrimination across package copies and realms while remaining structurally aligned with Effect domain errors.
+- Promise-client infrastructure failures use one generated `ClientError` class with a structured reason such as transport failure, unexpected status, unsupported content type, or malformed response. Promise methods reject with either a tagged declared domain failure or `ClientError`, matching the Effect client's conceptual domain/infrastructure error division.
+- Promise methods accept a separate optional per-call transport-options argument containing `AbortSignal` and header overrides. Cancellation and transport metadata do not enter the domain input object; broader interceptor and response-mode APIs remain deferred.
+- Promise streaming methods return a lazy `AsyncIterable` directly rather than a Promise-wrapped stream object. Iteration opens the connection, `AbortSignal` cancels it, and ending iteration closes the underlying request; the Effect emitter analogously returns `Stream` directly.
+- Promise SSE connection establishment, declared HTTP failures, and infrastructure failures occur during `AsyncIterable` iteration, beginning with its first `next()` call, rather than during synchronous method construction.
+- Neither generated streaming runtime automatically reconnects after disconnection. Promise `AsyncIterable` and Effect `Stream` fail explicitly; live consumers refresh and resubscribe, while durable sequence-based resume remains explicit composition above the generated client.
+- Promise client construction is synchronous and network-free. It requires `baseUrl`, defaults to `globalThis.fetch`, accepts client-level headers, and merges them with per-call header overrides.
+- Effect client construction accepts an explicit `baseUrl` and obtains `HttpClient.HttpClient` from the Effect environment. It does not install fetch or duplicate per-call transport policy; callers transform/provide the client for headers, tracing, retries, recording, and tests, while fiber interruption owns cancellation.
+- Promise and Effect emitters each own their generated public type modules. The **SDK Contract IR**, not a physically shared generated type package, is the common source; this permits zero-Effect wire types and rich decoded Effect types to evolve independently.
+- Promise and Effect network clients ship from `@opencode-ai/client` behind isolated root and `/effect` exports. The root has no runtime path to Effect; `/effect` imports only Effect, Schema, and Protocol.
+- The Effect-native scoped host belongs to `@opencode-ai/sdk-next`, which will assume the existing `@opencode-ai/sdk` name after legacy consumers migrate. Client remains network-only and SDK depends one-way on Client.
+- SDK executes Server's assembled `HttpRouter` in memory. It opens no listener and performs no network I/O, while preserving Server routing, middleware, codecs, handlers, and errors.
+- The Effect Client and SDK re-export their decoded datatype facade from Schema so callers do not depend on internal package locations or Core's versioned names.
+- A capability intended for both networked and **Embedded OpenCode** belongs in the authoritative public `HttpApi`; embedded-only same-process capabilities extend **Embedded OpenCode** separately.
+- `sessions.events({ sessionID, after })` is a public durable Session event stream. It verifies the Session, replays durable events after the optional aggregate sequence, continues with newly committed durable events, excludes live-only fragments, and is transported as SSE in both networked and embedded modes.
+- `events.subscribe()` is a distinct public instance-wide live stream for Session and non-Session activity. It has no replay guarantee and includes connection, heartbeat, and instance-disposal lifecycle events; consumers recover from disconnection by refreshing authoritative state.
+- A Session ID is not an optional filter on `events.subscribe()`: instance-wide live events and durable Session events have different schemas, replay guarantees, cursors, lifecycle events, and failure behavior.
+- The initial common OpenCode Client does not expose server-global event aggregation. `events.subscribe()` is bounded to the connected OpenCode instance or workspace; any future cross-instance administrative stream requires a separately designed API.
+- `events.subscribe()` does not automatically reconnect after transport loss. The live-only stream fails with `ClientError`; consumers refresh authoritative state before explicitly opening a new subscription because events missed during disconnection cannot be replayed.
+- `sessions.events({ sessionID, after })` returns the generated HTTP client's cold durable event stream and does not build reconnection policy into the endpoint or client constructor. Transport loss fails the stream with `ClientError`. Callers may compose an explicit resuming stream above it by retaining the last observed durable sequence and opening a new subscription with `after`; any reusable resume helper remains a separate API design question.
+- The stable `sessions.list(...)` design returns a **Page** in both networked and **Embedded OpenCode**; embedded execution does not define a separate unbounded array-returning list operation. The beta client currently preserves the existing HTTP `{ data, cursor }` envelope until emitter-level Page projection is implemented.
+- Session list cursors are opaque branded values carrying continuation query and ordering state. Consumers pass them back unchanged and do not inspect storage anchors or encoded filter fields.
+- A Session list continuation accepts only its opaque cursor. Scope, filters, ordering, and page size are fixed by the initial query and carried by that cursor.
+- `sessions.messages(...)` returns a **Page** and uses the same cursor discipline as `sessions.list(...)`: the initial request supplies `sessionID`, ordering, and page size; continuation supplies `sessionID` plus only an opaque branded message cursor carrying ordering, page size, direction, and message anchor. Using a cursor with another Session is invalid.
+- `sessions.message({ sessionID, messageID })` is a required resource lookup. An unknown Session fails with `SessionNotFoundError`; a known Session with an absent or differently owned message fails with `SessionMessageNotFoundError` without disclosing cross-Session ownership. Absence is not represented as `undefined` across the public HTTP boundary.
+- `sessions.interrupt({ sessionID })` first verifies that the durable Session exists, failing with `SessionNotFoundError` otherwise. For a known Session, interruption is idempotent: idle, already-settled, or locally unowned execution is a no-op.
+- `sessions.context({ sessionID })` preserves the existing message-only operation. It returns projected conversational messages selected as Session context; it does not include or represent the complete provider request context, whose baseline system context and other contributions remain separate.
+- **Open question**: Should a future, separately named operation expose the complete provider request context, including baseline system context, selected source contributions, and context-epoch metadata?
+- `sessions.prompt(...)` exposes `resume?: boolean`. Omitting it preserves durable admission followed by an advisory execution wake; `resume: false` requests durable admit-only behavior.
+- The public operation remains `sessions.prompt(...)`; `SessionInput.admit` is the internal primitive, while the public `Admission` result and `resume` option express its durable admission semantics.
+- `sessions.create(...)` accepts an optional `location`. Omission resolves through the connected OpenCode instance's default or current location; an explicit value selects a known location. Networked and embedded transports use the same handler semantics.
+- `sessions.switchAgent({ sessionID, agent })` is part of the common client alongside `sessions.switchModel(...)`. It affects subsequent Session activity and fails with `SessionNotFoundError` for an unknown Session.
+- The **Embedded OpenCode** Layer delegates to the same scoped creation path; it does not define a second implementation.
+- A **PTY Environment** adapter observes plugins in the request Location while passing the resolved PTY working directory to the hook; standalone servers use an empty adapter.
 - A **Mid-Conversation System Message** lowers to the provider's native chronological instruction role when supported and to a wrapped chronological fallback otherwise.
-- When an effective instruction file changes, its **Mid-Conversation System Message** includes the complete current contents and supersedes the prior version from that source; when it is removed, the message states that it no longer applies.
+- When the effective aggregate instruction set changes, its **Mid-Conversation System Message** includes the complete current ordered set and supersedes the prior aggregate value; when no ambient instructions remain, the message states that previously loaded instructions no longer apply.
+- Ambient project instruction discovery honors `OPENCODE_DISABLE_PROJECT_CONFIG`; global instructions remain eligible.
+- Oversized textual **Model Tool Output** retains a bounded preview in Session history while its complete text moves to managed tool-output storage. Arbitrary structured-result size is a separate concern.
+- One tool settlement receives one aggregate textual limit, using the configured maximum lines or UTF-8 bytes, whichever is reached first. The limit is provider-independent; token pressure belongs to context assembly and compaction.
+- Generic truncation preserves the beginning and end of textual output. Tools may apply a more meaningful strategy before the Tool Registry enforces the final limit.
+- A truncated **Model Tool Output** identifies its complete text both in the bounded model-visible preview and as a typed managed output path. Managed output paths do not modify the tool's validated structured result.
+- A **Managed Tool Output File** is temporary and may expire after its retention period. The bounded **Model Tool Output**, not the file, is the durable replayable record.
+- Failure to retain a **Managed Tool Output File** does not change a successful tool operation into a failed one. The Session records an explicitly lossy bounded output without a path, while operators receive diagnostics for the storage failure.
+- Once a tool operation succeeds, bounding its **Model Tool Output** and publishing its one durable settlement form an interruption-safe completion region. Raw oversized success is never published before a later correction.
+- When a structured-only result would exceed the **Model Tool Output** limit, its validated structured value remains unchanged for Session consumers while model replay uses a bounded textual JSON preview and optional managed output path.
+- Existing tool-managed output paths survive generic bounding. A fallback file retains exactly the complete projected text received by the Tool Registry and never claims to reconstruct output already discarded by tool-specific shaping.
+- **Managed Tool Output Files** use globally unique names in one shared flat directory. Their absolute paths are readable and searchable by ordinary tools; other absolute paths remain outside Location-scoped filesystem authority.
+- Provider-executed tool results remain provider-native transcript facts outside generic Tool Registry bounding. Their context control requires provider-aware pruning or compaction because some providers require exact structured round-trip payloads.
+
+## Client contract architecture
+
+Semantic values that mean the same thing internally and publicly live in the lightweight Schema leaf. Core consumes Schema for domain behavior; Protocol composes Schema values into paths, payloads, envelopes, errors, cursors, and streams; Server imports both, hosts Protocol's exact groups, and owns protocol/domain adaptation. The root Promise client remains zero-Effect, `/effect` depends on Effect plus Schema and Protocol, and `@opencode-ai/sdk-next` composes the scoped in-process host above Client, Core, and Server.
+
+Shared public records are plain objects declared with `Schema.Struct`. A same-name inferred interface gives object records readable TypeScript signatures without constructors, prototypes, or nominal identity; unions retain explicit type aliases.
+
+Before stabilizing the client API:
+
+- Keep additional public schemas in Schema and additional network groups in Protocol; neither package may transitively load databases, Drizzle, Session execution, providers, watchers, native modules, or WASM.
+- Keep concrete Location middleware keys in Server while Protocol owns their placement. Client projections may supply transport-only keys, but must prove generated equivalence with Server's concrete API.
+- Project the existing list response envelope to the stable client **Page** shape and enforce separate initial-query and cursor-continuation inputs without changing the hosted V2 wire contract.
+- Settle the stable consumer namespace (`session` versus the current beta `sessions`) and use an explicit codegen annotation if the consumer name should differ from the server group identifier.
+- Preserve V2 route paths, operation IDs, codecs, errors, middleware behavior, and OpenAPI output while making this change.
+- Preserve browser-safe `@opencode-ai/client` and `@opencode-ai/client/effect` bundles through import-boundary tests.
+- Define embedded-host placement before supporting multiple hosts over one database. Hosts that share durable Session storage must also share process-local Session execution coordination, or each host must receive isolated storage explicitly.
+- Keep an embedded request scope alive until any streamed response body finishes. The initial non-streaming Session surface does not exercise this lifetime boundary; Session and instance event streams must do so before joining the embedded client.

+# Manual app performance suite
+
+The app's high-volume performance diagnostics live under `packages/app/e2e/performance` and are excluded from normal local and CI Playwright discovery. The benchmark config builds the app and serves the production bundle before running scenarios serially.
+
+Run the suite explicitly from `packages/app`:
+
+```sh
+bun run test:bench
+```
+
+PowerShell:
+
+```powershell
+$env:PLAYWRIGHT_WORKERS = "1"
+bun run test:bench
+```
+
+The suite contains:
+
+- cold and hot session-tab timing
+- home-session click timing split between content and titlebar-tab paint
+- single-session tab close timing through stable home restoration
+- cached session repaint and mutation tracing
+- streaming timeline throughput, RAF-gap, long-task, geometry, and remount diagnostics
+
+All benchmarks import the shared `benchmark` fixture. Pages created through Playwright's `page` fixture automatically capture main-frame navigation history and emit a Chrome trace when `OPENCODE_PERFORMANCE_TRACE_DIR` is set. Benchmarks that need isolated browser contexts use `withBenchmarkPage`, which owns the context and the same diagnostics lifecycle.
+
+New benchmarks should look like normal Playwright tests:
+
+```ts
+import { benchmark, expect } from "../benchmark"
+
+benchmark("measures one interaction", async ({ page, report }) => {
+  // Only scenario-specific setup and interaction belong here.
+  report({ durationMs: 42 })
+})
+```
+
+The fixture requires every benchmark to call `report()`, automatically names and closes traces, captures navigation history, attaches that history when a test fails, and emits metrics as a consistent `BENCHMARK` JSON line.
+
+```text
+BENCHMARK {"name":"...","context":{"project":"chromium","platform":"darwin"},"metrics":{...}}
+```
+
+Every observed page also emits `BENCHMARK_PAGE` with the same run ID, navigation history, and optional trace path before the final status-bearing `BENCHMARK` record. Chrome traces are browser-wide page-lifetime diagnostics; scenario metrics use narrower explicitly named observation windows.
+
+This follows the stack's own guidance: [Electron recommends repeated Chrome DevTools and Chrome Tracing measurement](https://www.electronjs.org/docs/latest/tutorial/performance), [Chrome DevTools recommends Performance recordings for runtime work](https://developer.chrome.com/docs/devtools/performance), and [Playwright uses traces for test debugging rather than renderer profiling](https://playwright.dev/docs/trace-viewer).
+
+These Playwright benchmarks profile the shared app renderer in Chromium. A future packaged Electron benchmark that needs main-process and multi-process attribution should use Electron's official [`contentTracing`](https://www.electronjs.org/docs/latest/api/content-tracing/) API rather than extending this renderer harness with bespoke process instrumentation.
+
+CPU and high-volume visual profiling are disabled by default. Set `TIMELINE_CPU_PROFILE=1` to enable both, or additionally set `TIMELINE_VISUAL_PROFILE=0` for CPU-only profiling.
+
+The streaming scenario's 30x CPU throttle is a deterministic stress profile, not a simulated end-user device.
+
+Benchmarks do not assert machine-dependent performance budgets. Streaming processes 160 deltas by default and reports renderer-observed completion time, throughput, RAF callback-gap distributions, frame-budget equivalents, and long tasks through final geometry settlement. Delta count and delivery batch are included in result context when overridden. These are main-thread callback diagnostics, not compositor presentation or dropped-frame measurements. Visual-only and geometry metrics are `null` when their probes are disabled. Tab metrics describe sampled DOM observations. Assertions verify scenario and metric collection completion. Repeated repaint states are run-length grouped, but every original observation timestamp is retained alongside raw mutation batches and layout shifts.
+
+Committed smoke and regression tests continue to own correctness coverage for pagination, tab paint, context resize, collapse state, and composer spacing.
+
+## Chrome traces
+
+Set `OPENCODE_PERFORMANCE_TRACE_DIR` to emit a standard Chrome DevTools trace for every benchmark page automatically:
+
+```sh
+OPENCODE_PERFORMANCE_TRACE_DIR=/tmp/opencode-performance-traces \
+bunx playwright test --config e2e/performance/playwright.config.ts \
+  timeline/session-tab-switch-benchmark.spec.ts
+```
+
+The emitted JSON is a standard Chrome trace and can be loaded directly into the Chrome DevTools Performance panel. `devtools-tracing` can optionally inspect it from the command line without adding package scripts or dependencies:
+
+Trace capture mirrors [Puppeteer's official tracing defaults and lifecycle](https://pptr.dev/api/puppeteer.tracing), using Chrome's `ReturnAsStream` transfer mode and failing when Chromium reports trace data loss.
+
+```sh
+bunx devtools-tracing stats <trace-path-from-BENCHMARK_PAGE>
+```
+
+INP analysis requires a trace with a supported navigation/interaction insight. Selector statistics require a trace captured with `OPENCODE_PERFORMANCE_SELECTOR_TRACE=1`.
+
+`e2e/performance/playwright.uncapped.config.ts` disables Chromium frame-rate limiting for explicit uncapped diagnostics. Native product benchmarks should use the default Playwright configuration.

+# @opencode-ai/client
+
+Private generation target for clients derived directly from OpenCode's authoritative Effect `HttpApi`.
+
+## Entrypoints
+
+- `@opencode-ai/client`: zero-Effect Promise client using `fetch`.
+- `@opencode-ai/client/effect`: rich Effect network client using an environment-provided `HttpClient`.
+
+The generated surface starts with the Session group from Server's concrete API. The build compiler reads `@opencode-ai/server/api`; the generated Effect runtime imports a client-local projection built from Protocol, with a generation-equivalence test preventing transport drift. Run `bun run generate` after changing the contract and `bun run check:generated` to detect committed-output drift.
+
+The Effect entrypoint uses canonical decoded values such as `Session.ID`, `Location.Ref`, and `Prompt`. These datatypes come from the lightweight `@opencode-ai/schema` package and are re-exported so callers depend only on the client surface. Protocol owns endpoint construction and middleware placement; Server supplies the concrete middleware keys used by the build-time API.
+
+The Promise root remains structural and has no Core or Effect runtime dependency. `/effect` depends only on Effect, Schema, and Protocol and is browser-bundle safe. Bundle-boundary tests enforce both import graphs.
+
+Effect consumers construct canonical decoded inputs:
+
+```ts
+import { AbsolutePath, Location, OpenCode, Prompt } from "@opencode-ai/client/effect"
+
+const client = yield * OpenCode.make({ baseUrl: "https://opencode.example" })
+yield *
+  client.sessions.create({
+    location: Location.Ref.make({ directory: AbsolutePath.make("/workspace") }),
+  })
+yield * client.sessions.prompt({ sessionID, prompt: Prompt.make({ text: "Hello" }) })
+```

+- Only references with a `description` are advertised to agents in system context.
+- `hidden: true` removes a reference from TUI `@` autocomplete only. It remains available to agents and by direct path.
+- Reference directories are automatically allowed through the external-directory boundary; normal read/edit/tool permissions still apply.

+# Core Tool Architecture
+
+This folder owns Core's one local tool representation, process and Location registration, effective lookup, and settlement.
+
+## Representations
+
+- `tool.ts` defines the opaque canonical `Tool.make({ description, input, output, execute, toModelOutput })` value. Application tools and shipped built-ins use the same type.
+- `application-tools.ts` stores process-scoped application registrations.
+- `tools.ts` exposes the registration-only `Tools.Service` view used by Location producers.
+- `registry.ts` stores only canonical tools, overlays Location registrations over application registrations, derives definitions, invokes tools, and applies generic output bounding.
+
+Do not add a second executable entry type, registry-owned executor, authorization callback, output-path callback, or legacy normalization path.
+
+## Construction
+
+Tool schemas and projection use `input` and `output` terminology. A tool value is opaque: its codecs, executor, definition derivation, and catalog permission declaration are private runtime details.
+
+Location-scoped built-in layers acquire `PermissionV2.Service` and every other required Location service while the layer is constructed. The executor captures those services. Permission sources are always constructed from the canonical invocation context:
+
+```ts
+const source = {
+  type: "tool" as const,
+  messageID: context.assistantMessageID,
+  callID: context.toolCallID,
+}
+```
+
+Leaves own resolution, permission, and side-effect ordering. Translate only expected typed errors into `ToolFailure`; do not use `catchCause`, because interruption and defects must survive.
+
+## Registration
+
+Built-ins register through `Tools.Service.register({ [name]: tool })`. Application tools register through `ApplicationTools.Service.register(...)`, exposed publicly as `opencode.tools.register(...)`.
+
+Both are scoped:
+
+- The latest active same-placement registration wins.
+- Closing any registration removes only that registration and reveals the next active one.
+- Location registrations take precedence over application registrations.
+- An invocation captures the effective tool once settlement starts.
+
+`ApplicationTools.Service` is process-scoped and shared by all Locations. `ToolRegistry.Service` is Location-scoped. Do not make the registry process-global or construct a separate application-tool service for each Location.
+
+## Permissions
+
+The registry has no `PermissionV2.Service` dependency and performs no execution authorization. An internal built-in-only operation attaches a permission action solely to preserve whole-tool definition filtering; it is not part of public `Tool.make`. Most tools default to their registered name; `edit`, `write`, and `apply_patch` declare the shared `edit` action.
+
+Definition filtering is catalog visibility, not execution authorization. A call still executes the captured leaf policy if it reaches settlement.
+
+## Output
+
+Built-ins return complete validated domain output. `ToolRegistry.Materialization.settle` is the only execution and generic model-output bounding boundary and owns managed retention paths.
+
+Producer capture limits are separate. For example, Bash keeps `AppProcess.maxOutputBytes` and accurately reports stdout/stderr capture loss, but it does not run model-output truncation or return a managed `outputPath`.
+
+## Current Gaps
+
+- Plugin boot has not been redesigned to register canonical tools through `Tools.Service`; do not redesign it as part of leaf migrations.
+- MCP and future Session-scoped registrations still need an explicit canonical registration design.
+- The public Session result shape currently exposes managed `outputPaths`; full storage encapsulation requires a future opaque managed-output reference design.

 # @opencode-ai/http-recorder
 
-Record and replay HTTP and WebSocket traffic for Effect's `HttpClient`. Tests
-exercise real request shapes against deterministic, version-controlled
-cassettes — no manual mocks, no flakes from upstream drift.
+Record real Effect HTTP and WebSocket traffic once, then replay it from deterministic JSON cassettes.
+
+Use it for provider integrations, retries, polling, multi-step flows, and any test where hand-written HTTP mocks hide too much of the real request shape.
+
+> Public beta. The API depends on Effect 4 beta and may change with Effect's unstable transport modules.
 
 ## Install
 
-Internal package; depended on as `@opencode-ai/http-recorder` from another
-workspace package.
-
-```ts
-import { HttpRecorder } from "@opencode-ai/http-recorder"
+```sh
+bun add effect@4.0.0-beta.74
+bun add -d @opencode-ai/http-recorder@beta @effect/vitest vitest
 ```
 
-## Quickstart
+The package supports Node.js 22+ and Bun. It is not intended for browsers, workers, or Deno.
 
-Provide `cassetteLayer(name)` in place of (or layered over) your `HttpClient`.
-By default the layer records on first run and replays on subsequent runs —
-no env-var ternary at the call site, and `CI=true` forces strict replay so
-missing cassettes fail loudly in CI rather than silently re-recording.
-
-```ts
-import { Effect } from "effect"
-import { HttpClient, HttpClientRequest } from "effect/unstable/http"
-import { HttpRecorder } from "@opencode-ai/http-recorder"
-
-const program = Effect.gen(function* () {
-  const http = yield* HttpClient.HttpClient
-  const response = yield* http.execute(HttpClientRequest.get("https://api.example.com/users/1"))
-  return yield* response.json
-})
-
-// Records if the cassette is missing, replays if it exists.
-// In CI (CI=true) always replays — fails loudly on missing fixtures.
-Effect.runPromise(program.pipe(Effect.provide(HttpRecorder.cassetteLayer("users/get-one"))))
-
-// Force a refresh — always hits upstream and overwrites.
-Effect.runPromise(program.pipe(Effect.provide(HttpRecorder.cassetteLayer("users/get-one", { mode: "record" }))))
-```
-
-## Modes
-
-| Mode          | Behavior                                                                            |
-| ------------- | ----------------------------------------------------------------------------------- |
-| `auto`        | Default. Replay if the cassette exists; record if missing. `CI=true` forces replay. |
-| `replay`      | Strict — match the request to a recorded interaction; error if none.                |
-| `record`      | Execute upstream, append the interaction, write the cassette.                       |
-| `passthrough` | Bypass the recorder entirely — just call upstream.                                  |
-
-## Cassette format
-
-A cassette is JSON at `test/fixtures/recordings/<name>.json`:
+Effect `4.0.0-beta.74` has a known declaration error (`SchemaErrorTypeId` is missing). Until that upstream declaration is fixed, TypeScript consumers need:
 
 ```json
 {
-  "version": 1,
-  "metadata": { "name": "users/get-one", "recordedAt": "2026-05-09T..." },
-  "interactions": [
-    {
-      "transport": "http",
-      "request":  { "method": "GET", "url": "...", "headers": {...}, "body": "" },
-      "response": { "status": 200, "headers": {...}, "body": "..." }
-    }
-  ]
+  "compilerOptions": {
+    "skipLibCheck": true
+  }
 }
 ```
 
-Cassettes are normal source files — review them, diff them, commit them.
-
-## Request matching
-
-Replay walks the cassette in record order via an internal cursor: the Nth
-request executed at runtime is served by the Nth recorded interaction, and
-each one is validated as the cursor advances. Request equality is computed
-on canonicalized method, URL, headers, and JSON body (object keys sorted).
-
-This is deliberately strict — content-based dispatch was removed because
-it silently returns the first recorded response for repeated identical
-requests, masking state changes that retry/polling/cache-hit tests need to
-observe. If you reorder requests in a test, re-record the cassette.
-
-Supply your own matcher via `match: (incoming, recorded) => boolean` for
-custom equivalence (e.g. ignoring a timestamp field in the body).
-
-## Redaction & secret safety
-
-Cassettes get checked in, so the recorder is aggressive about not letting
-secrets escape. Redaction is configured by composing a `Redactor`:
-
-```ts
-import { HttpRecorder, Redactor } from "@opencode-ai/http-recorder"
-
-HttpRecorder.cassetteLayer("anthropic/messages", {
-  redactor: Redactor.defaults({
-    requestHeaders: { allow: ["content-type", "anthropic-version"] },
-    url: { transform: (url) => url.replace(/\/accounts\/[^/]+/, "/accounts/{account}") },
-    body: (parsed) => ({ ...(parsed as object), user_id: "{user}" }),
-  }),
-})
-```
-
-`Redactor.defaults({ … })` composes the four built-in redactors with your
-overrides. For full control, build the stack yourself:
-
-```ts
-const redactor = Redactor.compose(
-  Redactor.requestHeaders({ allow: ["content-type", "x-custom"] }),
-  Redactor.responseHeaders(),
-  Redactor.url({ query: ["session-id"] }),
-  Redactor.body((parsed) => /* … */),
-)
-```
-
-What each layer does:
-
-- **`requestHeaders` / `responseHeaders`** — strip headers to a small
-  allow-list (request default: `content-type`, `accept`, `openai-beta`;
-  response default: `content-type`). Sensitive headers within the
-  allow-list (`authorization`, `cookie`, API-key headers, AWS/GCP tokens,
-  …) are replaced with `[REDACTED]`.
-- **`url`** — query parameters matching common secret names (`api_key`,
-  `token`, `signature`, AWS signing params, …) are replaced with
-  `[REDACTED]`. URL user/password are replaced. `transform` runs after
-  built-in redaction for path-level scrubbing.
-- **`body`** — receives the parsed JSON request body and returns a redacted
-  version. No-op for non-JSON bodies.
-
-After assembling the cassette, the recorder scans every string for known
-secret patterns (Bearer tokens, `sk-…`, `sk-ant-…`, Google `AIza…` keys,
-AWS access keys, GitHub tokens, PEM blocks) and for values matching any
-environment variable named like a credential. If anything is found, the
-cassette is **not written** and the request fails with `UnsafeCassetteError`
-listing what was detected.
-
-## WebSocket recording
-
-WebSocket support records the open frame plus client/server message
-streams. It uses the shared `Cassette.Service`, so HTTP and WS interactions
-can live in the same cassette.

-`cassetteLayer` is the batteries-included entry point — it provides
-`Cassette.fileSystem({ directory })` automatically. If you want to provide
-your own `Cassette.Service` (e.g. an in-memory adapter for the recorder's
-own unit tests), use `recordingLayer` and supply `Cassette.fileSystem` /
-`Cassette.memory` yourself.
+Run the test with Vitest. The first local run calls the real API and records:
 
-## Options reference
+```sh
+bunx vitest run users.test.ts
+```
+
+```text
+test/fixtures/recordings/users/get-one.json
+```
+
+Later runs replay that cassette without contacting the upstream server. When `CI=true`, missing cassettes fail instead of recording.
+
+```mermaid
+flowchart TD
+  Run[Run test] --> Recorded{Cassette recorded?}
+  Recorded -->|Yes| Replay[Replay cassette]
+  Recorded -->|No, local| Record[Call service and record cassette]
+  Recorded -->|No, CI| Fail[Fail: cassette missing]
+```
+
+Application code does not need to know whether a response is live or replayed.
+
+## API
 
 ```ts
-type RecordReplayOptions = {
-  mode?: "auto" | "replay" | "record" | "passthrough" // default: "auto" (CI=true forces "replay")
-  directory?: string // default: <cwd>/test/fixtures/recordings
-  metadata?: Record<string, unknown> // merged into cassette.metadata
-  redactor?: Redactor // default: Redactor.defaults()
-  match?: (incoming, recorded) => boolean // custom matcher
+HttpRecorder.http(name, options?)
+HttpRecorder.socket(name, options?)
+```
+
+That is the complete public API. `http` provides a fetch-backed recorded `HttpClient`. `socket` decorates a standard Effect `Socket.Socket` supplied beneath it.
+
+## WebSockets
+
+WebSocket cassettes preserve one ordered transcript of client and server text or binary frames. Replay follows that chronology: server frames are released until the next recorded client frame, then replay waits for the application to send the matching frame before continuing.
+
+```ts
+import { assert, it } from "@effect/vitest"
+import { NodeSocket } from "@effect/platform-node"
+import { Effect, Layer } from "effect"
+import { Socket } from "effect/unstable/socket"
+import { HttpRecorder } from "@opencode-ai/http-recorder"
+
+const echo = Effect.gen(function* () {
+  const socket = yield* Socket.Socket
+  const write = yield* socket.writer
+
+  yield* socket.runString(
+    (message) =>
+      Effect.gen(function* () {
+        assert.strictEqual(message, "hello")
+        yield* write(new Socket.CloseEvent(1000))
+      }),
+    { onOpen: write("hello") },
+  )
+})
+
+const recordedSocket = HttpRecorder.socket("echo/hello").pipe(
+  Layer.provide(
+    NodeSocket.layerWebSocket("wss://ws.postman-echo.com/raw", {
+      closeCodeIsError: (code) => code !== 1000,
+    }),
+  ),
+)
+
+it.effect("exchanges WebSocket frames", () => echo.pipe(Effect.provide(recordedSocket)))
+```
+
+The application owns the WebSocket URL and protocols through normal Effect layer wiring. The recorder wraps that socket without duplicating its URL in recorder configuration. Provide separate socket layers for separate endpoints or concurrent connections.
+
+Text frames use the same JSON-field and body redaction as HTTP bodies. Binary frames are stored losslessly as base64. Client and server frame kinds must match during replay.
+
+## Refresh A Cassette
+
+Delete exactly the recordings you want to replace, then rerun their tests:
+
+```sh
+rm test/fixtures/recordings/users/get-one.json
+bun run test users.test.ts
+```
+
+There is intentionally no public overwrite mode. Deletion makes the set of recordings being refreshed visible and reviewable.
+
+## Redaction
+
+Secure defaults remove most headers and redact common credentials in headers, URLs, and JSON bodies. Extend those defaults at layer construction:
+
+```ts
+HttpRecorder.http("anthropic/messages", {
+  redact: {
+    headers: ["x-project-token"],
+    allowRequestHeaders: ["anthropic-version"],
+    queryParameters: ["session-id"],
+    jsonFields: ["user_id"],
+    url: (url) => url.replace(/\/accounts\/[^/]+/, "/accounts/{account}"),
+    body: (body) => body.replaceAll(/usr_[a-z0-9]+/g, "usr_redacted"),
+  },
+})
+```
+
+| Option                 | Purpose                                                              |
+| ---------------------- | -------------------------------------------------------------------- |
+| `headers`              | Add sensitive header names. They are retained as `[REDACTED]`.       |
+| `allowRequestHeaders`  | Preserve additional non-sensitive request headers for matching.      |
+| `allowResponseHeaders` | Preserve additional non-sensitive response headers for replay.       |
+| `queryParameters`      | Add sensitive URL query parameter names.                             |
+| `jsonFields`           | Recursively redact matching JSON keys in requests and responses.     |
+| `url`                  | Stabilize a URL after built-in redaction.                            |
+| `body`                 | Stabilize request and response bodies after built-in JSON redaction. |
+
+Before writing, the recorder scans the complete cassette for common credential formats and values from credential-like environment variables. Unsafe cassettes fail without replacing an existing recording.
+
+Redaction is defense in depth, not a substitute for review. Inspect cassette diffs before committing them.
+
+## Matching And Ordering
+
+A cassette contains an ordered sequence of interactions. The first runtime request is checked against the first recorded request, the second against the second, and so on.
+
+This strict ordering correctly models repeated identical requests whose responses change, including retries, polling, and cache tests. JSON object keys are canonicalized before matching.
+
+Concurrent requests are recorded in request-start order even when their responses complete out of order.
+
+Supply a custom equivalence rule when a request contains intentionally volatile data:
+
+```ts
+HttpRecorder.http("events/create", {
+  match: (incoming, recorded) =>
+    incoming.method === recorded.method && new URL(incoming.url).pathname === new URL(recorded.url).pathname,
+})
+```
+
+## Configuration
+
+```ts
+interface RecorderOptions {
+  readonly directory?: string
+  readonly metadata?: Record<string, unknown>
+  readonly redact?: RedactOptions
+  readonly match?: RequestMatcher
 }
 ```

+## Cassettes
+
+Cassettes are readable JSON files intended to be committed with your tests. HTTP interactions are stored in request order. WebSocket cassettes preserve the observed order of client and server frames. Text stays readable; binary bodies and frames are stored losslessly as base64.
+
+## Current Limits
+
+- Responses are buffered while recording and replaying, so this beta is not suitable for tests that assert streaming timing, cancellation, or backpressure.
+- WebSocket replay preserves frame chronology and content, not real network timing or backpressure.
+- WebSocket V1 cassettes do not reproduce terminal close codes, close reasons, or transport failures. Failed and interrupted live runs are not recorded.
+- WebSocket transcripts are retained in memory until the connection finishes; avoid using this beta for unbounded sessions.
+- The package currently requires the exact Effect beta listed above.
+- Cassette format version `1` has no migration tooling yet.

+# @opencode-ai/httpapi-codegen
+
+Build-time source generation for domain-oriented Promise and Effect APIs derived directly from `HttpApi` and Effect Schema contracts.
+
+The package is private while its API is explored. Its tests are the executable specification for the generator. It must remain independent of OpenCode Core and use synthetic `HttpApi` fixtures.
+
+## Settled rules
+
+- Reflect one authoritative `HttpApi` into a shared contract with `compile(Api)`.
+- Emit clients independently with `emitPromise(contract)` and `emitEffect(contract)`.
+- Give each emitter its own public type projection; the shared contract, not a generated type package, is the common source.
+- Generate a rich Effect client with decoded Effect-native values, runtime schemas, preserved transformations, and `HttpApiClient`.
+- Generate a zero-Effect Promise client with structural wire-oriented values, direct `fetch`, and syntax parsing without runtime structural validation.
+- Keep the Promise surface domain-oriented rather than Hey API compatible: methods return unwrapped values and reject with tagged declared errors or `ClientError`.
+- Return Promise streams as lazy `AsyncIterable` values and Effect streams as `Stream` values. Neither runtime reconnects automatically.
+
+- Flatten path, query, header, and payload fields into one input object.
+- Reject duplicate field names across input channels.
+- Emit no method argument for zero fields, an optional object when every field is optional, and a required object when any field is required.
+- Unwrap exact `{ data: A }` success envelopes.
+- Map no-content success to `void`.
+- Preserve other single success values.
+- Reject ambiguous multiple-success contracts.
+- Expose streaming success as `Stream`, not `Effect<Stream>`.
+- Reject schemas whose wire/domain transformation cannot be generated exactly.
+- Map transport, unexpected-status, and response-decoding failures to one stable generated `ClientError`.
+- Commit generated source for review; CI regenerates and fails when the worktree changes.
+- Track generated files in `.httpapi-codegen.json` so regeneration removes only stale files previously owned by the generator.
+
+## Boundary
+
+This package generates only client APIs derived from `HttpApi`. It does not generate embedded-only capabilities. Networked and embedded OpenCode use the same generated Effect client against network and in-memory `HttpClient` transports respectively; the embedded host structurally extends that client with same-process capabilities.
+
+Codegen generates every endpoint in the `HttpApi` it receives. OpenCode owns the product decision by composing the exact remote API before invoking the generator; the generic package has no endpoint filtering policy.
+
+The existing public `generate(Api, { directory })` operation writes the rich Effect output and remains an Effect requiring `FileSystem`. The staged API uses pure `compile(Api)`, `emitEffect(contract)`, and `emitPromise(contract)` phases before `write(output, directory)`. Compiler tests inspect virtual files directly; writer tests use `FileSystem.makeNoop`.
+
+Generation formats TypeScript with Prettier before writing. Output paths are flat, unique, and checked against traversal, reserved manifest names, and existing symbolic links.
+
+Generated source starts with one self-contained module per `HttpApiGroup`, plus root client and index modules. Schema dependencies may be duplicated across group modules. Cross-group schema partitioning is deferred until measured output or bundle cost requires it.
+
+Codegen preserves group and endpoint identifiers exactly. The composed remote `HttpApi` owns public names such as `session` and `get`; the generator performs no prefix stripping, casing conversion, or public-name annotation mapping.

AWS Bedrock streams binary AWS event-stream frames whose CRC32 fields would be mangled by a UTF-8 round-trip — those bodies are stored as base64 with `bodyEncoding: "base64"` on the response snapshot. Detection is by `Content-Type` in `@opencode-ai/http-recorder` (currently `application/vnd.amazon.eventstream` and `application/octet-stream`); cassettes for SSE/JSON routes omit the field and decode as text.
+**Binary response bodies.** Most providers stream text (SSE, JSON). The recorder treats known textual media types (`text/*`, JSON/XML structured types, JavaScript, forms, YAML, and SVG) as text and stores every other response as base64 with `bodyEncoding: "base64"`. This preserves binary formats such as AWS event-stream frames without a lossy UTF-8 round trip.
 
 **Matching strategy.** Replay walks the cassette in record order via an internal cursor: the Nth runtime request is served by the Nth recorded interaction, and each one is validated by comparing method, URL, allow-listed headers, and the canonical JSON body. This handles tool loops (each round's request differs as history grows) and retry/polling scenarios (successive byte-identical requests with different responses) uniformly. If a test reorders its requests, re-record the cassette. `scriptedResponses` (in `test/lib/http.ts`) is the deterministic counterpart for tests that don't need a live provider; it scripts response bodies in order without reading from disk.

+# AI Library Design
+
+> Discussion draft. This document describes the intended replacement for the
+> current private `@opencode-ai/llm` API. Names and exact TypeScript signatures
+> are illustrative until implementation, but the domain boundaries and defaults
+> are deliberate.
+
+## Status
+
+- Proposed package: `@opencode-ai/ai`
+- Initial stable domain: `LLM`
+- Release posture: pre-1.0, with a stable-core intent
+- Migration posture: clean break; do not preserve compatibility aliases
+- Primary audience: general-purpose TypeScript developers using Effect
+- Secondary audience: OpenCode and other durable agent runtimes
+
+The package name leaves room for future domains such as embeddings, images, and
+speech. Those domains are not part of this design and should not be forced into
+the LLM run/turn model.
+
+## Goals
+
+1. Make a useful model call require very little code.
+2. Make the default behavior good enough that most callers do not configure it.
+3. Let advanced callers inspect, transform, or replace every important stage.
+4. Keep provider quirks behind provider and protocol boundaries.
+5. Preserve one provider turn as an explicit primitive for durable runtimes.
+6. Keep serializable request data separate from process-local execution behavior.
+7. Make unsupported combinations fail locally with useful typed errors.
+8. Stay Effect-native without making package-specific service provisioning part
+   of every call site.
+
+## Non-goals
+
+- A global provider or model registry
+- Durable agent orchestration or persistence
+- Session history ownership
+- Permission handling
+- Cost billing or accounting guarantees
+- Runtime model-catalog network requests
+- Compatibility with the current private API
+- Designing embeddings, image generation, speech, or transcription now
+
+## Design Principles
+
+### Progressive disclosure
+
+The API has four layers:
+
+1. **Run a model** with `LLM.generate` or `LLM.stream`.
+2. **Control one provider turn** with `LLM.generateTurn` or `LLM.streamTurn`.
+3. **Customize execution** with model defaults, call options, hooks, and provider
+   configuration.
+4. **Author providers** with experimental provider definitions and protocols.
+
+Normal documentation should teach only the first layer initially.
+
+### Values over registries
+
+Provider definitions, configured providers, models, protocols, tools, and hooks
+are immutable values. Importing a provider does not register anything globally.
+
+### Portable data, local behavior
+
+Requests, messages, tool definitions, events, usage, and result projections are
+plain immutable data with schemas. Configured models, executable tools, hooks,
+and provider definitions may contain functions and Effect requirements and are
+not serializable.
+
+### Strong defaults, explicit overrides
+
+Defaults should make common calls correct without hiding where behavior comes
+from. Overrides compose in a documented order and never require patching
+installed dependencies.
+
+## Domain Model
+
+### Provider Definition
+
+An immutable, declarative description of a provider integration. It owns model
+selection, option schemas, catalog corrections, protocols, and provider-wide
+hooks. It is an experimental provider-authoring API.
+
+### Configured Provider
+
+A provider definition bound to deployment concerns such as credentials,
+endpoint, transport, and provider headers.
+
+`configure(...)` is intentionally deployment-only. It does not establish hidden
+generation defaults.
+
+### Model
+
+A process-local executable model value selected from a configured provider. It
+contains identity, capabilities, pricing metadata, provider-specific option
+types, reusable request-behavior defaults, and hidden execution behavior.
+
+Normal users do not need to learn the current `Route` composite. Protocol,
+endpoint, auth, transport, and hooks are bound behind `Model`.
+
+### Request
+
+Portable, model-independent input for a model call. It may contain system
+instructions, messages, tool definitions, generation controls, output intent,
+cache policy, and metadata. It does not contain a configured model, executable
+tool handlers, or hooks.
+
+### Provider Turn
+
+Exactly one request to a model provider and its normalized response. It does not
+execute local tools or continue the conversation.
+
+### Model Run
+
+A complete interaction consisting of one or more provider turns. A run executes
+local tools, appends their results, and continues until the model completes or a
+stopping condition matches.
+
+### TurnResult
+
+The result of exactly one provider turn.
+
+### GenerateResult
+
+The result of a complete model run. It preserves every turn, tool activity,
+aggregate usage, and estimated cost while exposing shortcuts to the final output.
+
+### Protocol
+
+The provider-wire contract that lowers portable requests into provider-native
+bodies and raises provider-native stream events into normalized turn events.
+Protocols are public, reusable, fully inspectable, and immutably patchable, but
+the entire protocol-authoring API is experimental.
+
+## Happy Path
+
+### Effect
+
+```ts
+import { Effect } from "effect"
+import { LLM } from "@opencode-ai/ai"
+import { OpenAI } from "@opencode-ai/ai/providers/openai"
+
+// Environment-based credentials are a provider default. No LLMClient layer is
+// required: the Effect exposes standard runtime dependencies directly.
+const model = OpenAI.model("gpt-4.1-mini")
+
+const program = Effect.gen(function* () {
+  const result = yield* LLM.generate({
+    model,
+    system: "You are concise.",
+    prompt: "Explain Effect in one sentence.",
+  })
+
+  // `generate` always returns GenerateResult, even when the run has one turn.
+  console.log(result.text)
+  console.log(result.turns.length) // 1
+  console.log(result.usage)
+  console.log(result.cost) // Estimated cost, or undefined if any turn is unpriced.
+})
+```
+
+The required Effect environment should contain standard services plus services
+required by tools and hooks. It should not contain an `LLMClient` wrapper service.
+
+### Current API
+
+The current README appears similarly small but omits the package-specific service
+and layer required at runtime:
+
+```ts
+// Current API: this request contains an executable model/route value.
+const request = LLM.request({
+  model: OpenAI.configure({ apiKey }).responses("gpt-4o-mini"),
+  prompt: "Say hello.",
+})
+
+// Current API: this performs one provider turn, despite the broad name.
+const response = yield * LLM.generate(request)
+
+// Current API: execution also needs LLMClient.layer and RequestExecutor services.
+```
+
+The proposal removes mandatory request construction, removes package-specific
+runtime provisioning, and makes `generate` mean a complete run.
+
+## Provider And Model Selection
+
+### Environment defaults
+
+```ts
+import { OpenAI } from "@opencode-ai/ai/providers/openai"
+
+// Open strings receive autocomplete for IDs from the generated models.dev
+// snapshot but continue to accept newly released and fine-tuned model IDs.
+const model = OpenAI.model("gpt-4.1-mini")
+```
+
+### Deployment configuration
+
+```ts
+const openai = OpenAI.configure({
+  apiKey,
+  baseURL: "https://gateway.example.com/openai/v1",
+  headers: {
+    "x-tenant": "acme",
+  },
+})
+
+const model = openai.model("gpt-4.1-mini")
+```
+
+`configure(...)` owns deployment concerns only:
+
+- Credentials and authentication
+- Base URL and deployment location
+- Transport selection
+- Provider/deployment headers
+- Other provider-specific connection setup
+
+It does not own temperature, maximum output tokens, cache policy, retry policy,
+tools, output schema, or system instructions.
+
+### Reusable model defaults
+
+```ts
+const model = OpenAI.model("gpt-4.1-mini", {
+  generation: {
+    temperature: 0.2,
+    maxTokens: 2_000,
+  },
+  cache: "auto",
+  provider: {
+    store: false,
+  },
+})
+```
+
+The second argument may default request behavior but not prompt/history or
+executable tools. Call-level values override model defaults.
+
+Provider-specific options are inferred from the concrete model:
+
+```ts
+yield *
+  LLM.generate({
+    model: OpenAI.model("gpt-4.1-mini"),
+    prompt: "Hello",
+    provider: {
+      store: false,
+      // OpenAI-specific autocomplete here; no `{ openai: ... }` nesting.
+    },
+  })
+```
+
+Code choosing between providers dynamically must narrow the model before using
+provider-specific options. Portable generation controls remain available without
+narrowing.
+
+### Current API
+
+```ts
+// Current API mixes deployment configuration and reusable request behavior.
+const model = OpenAI.configure({
+  apiKey,
+  generation: { maxTokens: 160 },
+  providerOptions: {
+    openai: { store: false },
+  },
+}).model("gpt-4o-mini")
+```
+
+The proposal separates deployment configuration from selected-model behavior and
+removes provider-keyed option bags when a concrete model already identifies the
+provider.
+
+## Requests
+
+### Inline input
+
+```ts
+const result =
+  yield *
+  LLM.generate({
+    model,
+    system: "You are concise.",
+    prompt: "Summarize this pull request.",
+    generation: { maxTokens: 500 },
+  })
+```
+
+### Reusable portable request
+
+```ts
+const request = LLM.request({
+  system: "You are concise.",
+  prompt: "Summarize this pull request.",
+  generation: { maxTokens: 500 },
+})
+
+// Bind process-local execution behavior only when running.
+const result = yield * LLM.generate({ model, request })
+```
+
+`LLM.request(...)` returns a plain immutable object. Use ordinary object spread
+to derive another request:
+
+```ts
+const longer = {
+  ...request,
+  generation: {
+    ...request.generation,
+    maxTokens: 1_000,
+  },
+}
+```
+
+There is no `LLM.updateRequest(...)` helper and no request Schema class.
+
+### Conversation history
+
+```ts
+import { Message } from "@opencode-ai/ai"
+
+const request = LLM.request({
+  system: "You are concise.",
+  messages: [
+    Message.user("What is Effect?"),
+    Message.assistant("A TypeScript library for typed functional effects."),
+    Message.user("Why would I use it?"),
+  ],
+})
+```
+
+Message helpers return plain immutable data. Object literals remain valid when
+they satisfy the same input type.
+
+`system` stays separate from chronological messages because it is the initial
+privileged instruction. A chronological system message represents an instruction
+change at a specific point in history.
+
+## Complete Runs
+
+### Automatic local tool loop
+
+```ts
+import { Effect, Schema } from "effect"
+import { LLM, Tool } from "@opencode-ai/ai"
+
+const tools = {
+  getWeather: Tool.make({
+    description: "Get current weather for a city.",
+    parameters: Schema.Struct({ city: Schema.String }),
+    success: Schema.Struct({ forecast: Schema.String }),
+
+    // Tool service requirements and typed errors flow into LLM.generate's
+    // Effect environment/error model instead of being erased.
+    execute: ({ city }) => Weather.get(city),
+
+    // Expected domain failures need an explicit model-visible representation.
+    formatError: (error) => ({
+      type: "text",
+      text: `Weather lookup failed: ${error.message}`,
+    }),
+  }),
+}
+
+const result =
+  yield *
+  LLM.generate({
+    model,
+    prompt: "What is the weather in London?",
+    tools,
+  })
+
+// The runtime advertises definitions, dispatches calls, records results, and
+// continues provider turns automatically.
+console.log(result.text)
+console.log(result.turns)
+console.log(result.toolExecutions)
+```
+
+The default stopping condition is equivalent to:
+
+```ts
+stopWhen: StopWhen.turnCount(20)
+```
+
+This matches the Vercel AI SDK `ToolLoopAgent` default. Reaching the limit is a
+successful result with `stopReason: "max-turns"`, not an Effect failure.
+
+### Custom stopping
+
+```ts
+const result =
+  yield *
+  LLM.generate({
+    model,
+    prompt,
+    tools,
+    stopWhen: StopWhen.any(StopWhen.turnCount(8), StopWhen.hasToolCall("finalize")),
+  })
+```
+
+`stopWhen` accepts one predicate. Composition is explicit through combinators
+such as `StopWhen.any`, `StopWhen.all`, and `StopWhen.not`.
+
+Successful run stop reasons are closed:
+
+```ts
+type RunStopReason = "completed" | "max-turns" | "stop-condition"
+```
+
+### Tool concurrency
+
+Independent tool calls emitted in one turn run concurrently with a bounded,
+configurable concurrency limit. Results are appended in deterministic emitted
+order. The runtime does not infer dependencies between tool calls; the model must
+request dependent calls in separate turns.
+
+Tools may declare an optional timeout. The overall run timeout still applies.
+
+### Current API
+
+Today callers must manually bridge every layer:
+
+```ts
+const request = LLM.request({
+  model,
+  prompt,
+  tools: Tool.toDefinitions(tools),
+})
+
+const events = yield * LLM.stream(request).pipe(Stream.runCollect)
+const call = Array.from(events).find(LLMEvent.is.toolCall)
+
+if (call && !call.providerExecuted) {
+  const dispatched = yield * ToolRuntime.dispatch(tools, call)
+  const followUp = LLM.updateRequest(request, {
+    messages: [...request.messages, Message.assistant([call]), Message.tool({ ...call, result: dispatched.result })],
+  })
+  // Caller must invoke the provider again and repeat the loop.
+}
+```
+
+That explicit flow remains possible through turn APIs, but it is no longer the
+only tool experience.
+
+## One Provider Turn
+
+OpenCode and other durable runtimes need to own persistence, tool settlement,
+and continuation. They use the explicit turn API:
+
+```ts
+const result =
+  yield *
+  LLM.generateTurn({
+    model,
+    request,
+    // Definitions only. generateTurn never dispatches local handlers.
+    tools: {
+      getWeather: Tool.definition({
+        description: "Get current weather for a city.",
+        parameters: WeatherInput,
+      }),
+    },
+  })
+
+// Persist the TurnResult and settle calls durably before the next turn.
+for (const call of result.toolCalls) {
+  // Application-owned dispatch and persistence.
+}
+```
+
+`generateTurn` and `streamTurn` make exactly one provider request. They never
+execute a local tool and never continue automatically.
+
+This separation is load-bearing:
+
+- `generate` / `stream`: complete Model Run
+- `generateTurn` / `streamTurn`: one Provider Turn
+
+## Portable Tool Definitions
+
+A portable request may declare serializable definitions, but executable handlers
+are bound at run time:
+
+```ts
+const request = LLM.request({
+  prompt: "What is the weather in London?",
+  tools: {
+    getWeather: Tool.definition({
+      description: "Get current weather for a city.",
+      parameters: WeatherInput,
+    }),
+  },
+})
+
+const result =
+  yield *
+  LLM.generate({
+    model,
+    request,
+    tools: {
+      getWeather: Tool.make({
+        description: "Get current weather for a city.",
+        parameters: WeatherInput,
+        success: WeatherOutput,
+        execute: getWeather,
+        formatError,
+      }),
+    },
+  })
+```
+
+Definitions and handlers match by record key. Before the first provider call,
+the runtime validates that every local definition has a compatible executable
+binding. Missing or incompatible bindings fail with a typed tool-binding error.
+
+Provider-hosted tools are distinct typed values:
+
+```ts
+const result =
+  yield *
+  LLM.generate({
+    model: OpenAI.model("gpt-4.1"),
+    prompt: "Find today's relevant announcements.",
+    tools: {
+      search: OpenAI.tool.webSearch({ searchContextSize: "medium" }),
+    },
+  })
+```
+
+Hosted tools do not pretend to have local handlers, and callers do not inspect a
+`providerExecuted` boolean to decide whether dispatch is safe.
+
+## Streaming
+
+### Run stream
+
+`LLM.stream` returns an Effect `Stream<RunEvent, LLMError, Requirements>`.
+Run events explicitly expose orchestration boundaries:
+
+```ts
+const program = LLM.stream({ model, prompt, tools }).pipe(
+  Stream.tap((event) =>
+    Effect.sync(() => {
+      switch (event.type) {
+        case "run-start":
+          break
+        case "turn-start":
+          break
+        case "turn-event":
+          // Normalized text, reasoning, tool-call, usage, and finish events.
+          if (event.event.type === "text-delta") {
+            process.stdout.write(event.event.text)
+          }
+          break
+        case "tool-start":
+          break
+        case "tool-finish":
+          break
+        case "turn-finish":
+          break
+        case "run-finish":
+          // Contains the same full GenerateResult returned by LLM.generate.
+          console.log(event.result.usage)
+          break
+      }
+    }),
+  ),
+  Stream.runDrain,
+)
+```
+
+Exact event tag spelling remains an implementation detail to finalize, but the
+algebra is settled:
+
+- A separate `RunEvent` union for run, turn, and tool lifecycle
+- A focused `TurnEvent` union for normalized provider output
+- `streamTurn` emits only `TurnEvent`
+- The terminal run event contains the full `GenerateResult`
+
+External cancellation remains Effect interruption. It does not fabricate a
+successful result with an `interrupted` stop reason.
+
+## Structured Output
+
+Structured output is an option on `generate`, not a separate operation:
+
+```ts
+const Weather = Schema.Struct({
+  city: Schema.String,
+  forecast: Schema.String,
+  highCelsius: Schema.Number,
+})
+
+const result =
+  yield *
+  LLM.generate({
+    model,
+    prompt: "Give me today's weather for London.",
+    output: Weather,
+  })
+
+// Inferred from Weather.
+result.output.city
+```
+
+The model declaration and protocol select the best reliable strategy:
+
+1. Provider-native structured output when supported and reliable
+2. Forced tool output when required as a compatibility fallback
+3. Typed unsupported-capability failure before network execution when neither is
+   available
+
+Advanced callers may override the strategy when exact provider semantics matter.
+
+### Current API
+
+```ts
+// Current API is a separate operation and always forces a synthetic tool.
+const result =
+  yield *
+  LLM.generateObject({
+    model,
+    prompt,
+    schema: Weather,
+  })
+```
+
+The proposal unifies generation and lets capabilities choose the strategy rather
+than permanently encoding one cross-provider workaround.
+
+## Model Catalog
+
+`models.dev` is the release-time source for:
+
+- Model ID suggestions
+- Capabilities and modalities
+- Context and output limits
+- Pricing
+- Other available model metadata
+
+The package ships a generated, versioned snapshot. Normal execution performs no
+catalog network requests.
+
+Provider definitions may correct generated metadata where protocol-specific
+knowledge is more accurate. Precedence is:
+
+```text
+models.dev snapshot
+  < provider-definition correction
+  < provider configuration override
+  < model-selection override
+  < call override
+```
+
+Unknown model IDs inherit only capabilities guaranteed by the selected protocol.
+Unsupported request capabilities fail before network execution unless the caller
+explicitly overrides the model declaration.
+
+## Usage And Cost
+
+`GenerateResult` aggregates normalized usage across every turn, including cache
+read/write usage where providers report it.
+
+It also exposes estimated cost using the generated models.dev pricing snapshot:
+
+```ts
+result.usage.inputTokens
+result.usage.outputTokens
+result.usage.cacheReadInputTokens
+result.usage.cacheWriteInputTokens
+
+result.cost?.total
+result.cost?.currency // e.g. "USD"
+```
+
+Cost is an estimate, not a billing guarantee. If reliable pricing is unavailable
+for any turn, aggregate run cost is unavailable rather than partial or silently
+zero. Per-turn metadata should retain the catalog/pricing identity used so an
+estimate can be explained.
+
+## Caching
+
+Prompt caching remains `"auto"` by default. The library places protocol-aware
+cache boundaries where explicit caching is supported and does nothing on the wire
+where providers cache implicitly.
+
+```ts
+yield *
+  LLM.generate({
+    model,
+    prompt,
+    cache: "none", // Explicit opt-out.
+  })
+```
+
+Granular cache policy remains available as an advanced request option.
+
+## Retries, Timeouts, And Cancellation
+
+### Retries
+
+The default retry policy is deliberately conservative:
+
+- Retry bounded transient transport and rate-limit failures
+- Retry only before observable output
+- Never silently retry after ambiguous tool execution or other side effects
+- Allow each call to override or disable retry behavior
+
+Retry configuration is call-scoped only. Provider and model configuration do not
+silently inherit custom retry policies.
+
+### Timeouts
+
+```ts
+yield *
+  LLM.generate({
+    model,
+    prompt,
+    timeout: "2 minutes", // Entire run, including tools.
+    turnTimeout: "30 seconds", // Each provider turn.
+    tools,
+  })
+```
+
+Exact Duration input spelling follows Effect conventions. Individual tools may
+also declare optional timeouts.
+
+### Cancellation
+
+- Effect API: fiber interruption
+- Promise API: `AbortSignal`, rejecting with a recognizable abort error
+- Cancellation is not a successful run stop reason
+
+## Hooks
+
+Stable high-level hooks exist at five named stages:
+
+1. Canonical request
+2. Provider-native body
+3. Prepared transport request
+4. Normalized event
+5. Error
+
+Hooks are Effectful. They may transform the stage value or fail with a typed
+error. They may not secretly short-circuit execution, synthesize a response,
+retry, or redirect control flow.
+
+```ts
+const model = OpenAI.model("gpt-4.1", {
+  hooks: {
+    request: (request) =>
+      Effect.succeed({
+        ...request,
+        metadata: { ...request.metadata, tenant: "acme" },
+      }),
+    body: (body, context) => auditBody(body, context),
+    transport: (request) => signInternalGatewayRequest(request),
+    event: (event) => redactProviderMetadata(event),
+    error: (error) => classifyInternalError(error),
+  },
+})
+```
+
+Hook scopes compose in this order:
+
+```text
+provider-definition hooks -> model hooks -> call hooks
+```
+
+Each hook sees the prior hook's output. Replacement requires an explicit
+definition-level patch, not accidental last-writer-wins semantics.
+
+Provider-definition hooks are authored by provider integrations. They are not
+passed through `Provider.configure(...)`, which remains deployment-only.
+
+## HTTP And Provider Escape Hatches
+
+The request customization ladder is:
+
+1. Portable generation controls
+2. Model-typed `provider` options
+3. Stable staged hooks
+4. Serializable HTTP/body overlays
+5. Experimental provider-definition or protocol patching
+
+```ts
+yield *
+  LLM.generate({
+    model,
+    prompt,
+    http: {
+      headers: { "x-experimental": "1" },
+      query: { debug: "true" },
+      body: { newlyReleasedProviderField: true },
+    },
+  })
+```
+
+Raw overlays are intentional last-resort support for provider features that ship
+before the library has a typed option.
+
+## Provider-Native Metadata
+
+Normalized message/content/event unions remain closed and exhaustive. Unknown or
+provider-required round-trip data lives in caller-writable `providerMetadata`.
+
+```ts
+const assistant = Message.assistant([
+  {
+    type: "reasoning",
+    text: "...",
+    providerMetadata: {
+      openai: {
+        // Opaque provider data needed for replay or continuation.
+      },
+    },
+  },
+])
+```
+
+Protocols validate metadata they consume. The field is an escape hatch, not a
+portable semantic guarantee.
+
+## Error Model
+
+The Effect error channel is a tagged domain union rather than one `LLMError`
+wrapper with nested reasons. Illustrative categories:
+
+```ts
+type LLMError =
+  | AuthenticationError
+  | InvalidRequestError
+  | UnsupportedCapabilityError
+  | ToolBindingError
+  | TransportError
+  | ProviderResponseError
+  | InvalidProviderOutputError
+  | HookError
+```
+
+Each error retains relevant provider/model/turn/stage context and its underlying
+cause where available.
+
+Expected tool errors keep their own typed error channel. `Tool.make` requires an
+explicit mapping before such errors become model-visible tool results. Expected
+mapped failures let the model recover; defects and interruption fail the run.
+
+## Observability
+
+The core library emits Effect-native spans and metrics for:
+
+- Model runs
+- Provider turns
+- Provider requests
+- Retries
+- Tool executions
+
+Default telemetry records metadata only:
+
+- Provider and model identity
+- Timing
+- Token/cache usage
+- Estimated cost availability
+- Finish and stop reasons
+- Retry counts
+- Tool names
+
+Prompts, model output, tool arguments, and tool results are never recorded by
+default. Explicit hooks or telemetry configuration may opt into content capture.
+
+## Promise API
+
+Promise wrappers live at a separate subpath so the root remains unambiguously
+Effect-first:
+
+```ts
+import { LLM } from "@opencode-ai/ai/promise"
+import { OpenAI } from "@opencode-ai/ai/providers/openai"
+
+const result = await LLM.generate({
+  model: OpenAI.model("gpt-4.1-mini"),
+  prompt: "Explain Effect in one sentence.",
+  signal: abortController.signal,
+})
+```
+
+Streaming returns an `AsyncIterable<RunEvent>`:
+
+```ts
+for await (const event of LLM.stream({ model, prompt, signal })) {
+  if (event.type === "turn-event" && event.event.type === "text-delta") {
+    process.stdout.write(event.event.text)
+  }
+}
+```
+
+Top-level Promise functions use a default runtime for built-in services. Custom
+Effect service requirements use a configured client:
+
+```ts
+const client = LLM.makeClient({
+  layer: Layer.mergeAll(WeatherLive, AuditLive),
+})
+
+const result = await client.generate({ model, prompt, tools })
+```
+
+The Promise API mirrors Effect semantics. It does not invent different run,
+error, stopping, or cancellation behavior.
+
+## Schemas
+
+Schemas live in a dedicated namespace/subpath instead of flooding root exports:
+
+```ts
+import { LLMSchema } from "@opencode-ai/ai/schema"
+
+const request = yield * Schema.decodeUnknown(LLMSchema.Request)(input)
+```
+
+Schemas cover only serializable domain values:
+
+- Requests and messages
+- Portable tool definitions
+- Turn and run events
+- Serializable result projections
+- Usage and cost estimates
+- Tagged errors where serializable
+- Provider metadata containers
+
+Configured models, executable tools, hooks, provider definitions, and protocols
+are process-local behavior and do not receive fake serialization schemas.
+
+## Provider Authoring
+
+Provider authoring is public but experimental.
+
+### Declarative provider definition
+
+```ts
+import { Provider, Protocol } from "@opencode-ai/ai/provider"
+
+export const ExampleAI = Provider.define({
+  id: "example",
+  options: ExampleProviderOptions,
+  configure: configureExampleDeployment,
+  protocols: {
+    responses: ExampleResponses,
+  },
+  models: ({ deployment, catalog }) => ({
+    model: (id, defaults) =>
+      Provider.model({
+        id,
+        deployment,
+        protocol: ExampleResponses,
+        metadata: catalog.model(id),
+        defaults,
+      }),
+  }),
+  catalog: generatedExampleCatalog,
+  corrections: exampleCatalogCorrections,
+  hooks: exampleProviderHooks,
+})
+```
+
+The exact builder fields need implementation design, but it must remain one
+declarative immutable object, infer provider option types, and support `.with(...)`
+patching. It must not register globally.
+
+Built-ins export their immutable definition for advanced forking:
+
+```ts
+import { OpenAI } from "@opencode-ai/ai/providers/openai"
+
+const PatchedOpenAI = OpenAI.definition.with({
+  protocols: {
+    responses: OpenAI.protocols.responses.with({
+      // Explicit immutable stage patch.
+      body: {
+        fromRequest: patchResponsesBody,
+      },
+    }),
+  },
+})
+```
+
+### Protocols
+
+A protocol exposes all native types and stages:
+
+- Provider-native request body and schema
+- Transport frame type
+- Provider-native event and schema
+- Parser state
+- Request lowering
+- Event stepping
+- Terminal detection and final flushing
+
+Every stage is immutably patchable. This is deliberately more open than the AI
+SDK integrations that motivated this package.
+
+```ts
+const PatchedResponses = OpenAIResponses.with({
+  body: {
+    fromRequest: (request) =>
+      OpenAIResponses.body.fromRequest(request).pipe(Effect.map((body) => ({ ...body, custom_field: true }))),
+  },
+  stream: {
+    step: patchResponsesStep,
+  },
+})
+```
+
+Protocol body, frame, native event, and parser-state types are exported. Because
+provider wire formats change often, these types and patch APIs are explicitly
+experimental and do not receive the high-level API's compatibility promise.
+
+## Package Surface
+
+Illustrative export layout:
+
+```text
+@opencode-ai/ai
+  LLM
+  Message
+  Tool
+  StopWhen
+  stable domain types
+
+@opencode-ai/ai/promise
+  Promise/AsyncIterable LLM facade
+
+@opencode-ai/ai/schema
+  serializable domain schemas
+
+@opencode-ai/ai/provider
+  experimental Provider and Protocol authoring APIs
+
+@opencode-ai/ai/providers/openai
+@opencode-ai/ai/providers/anthropic
+@opencode-ai/ai/providers/google
+...
+```
+
+Providers are imported through individual subpaths. The root does not export all
+providers, and there is no preferred all-providers barrel.

+| Mandatory `LLM.request({ model, ... })` | Inline calls or model-free portable requests                |

+| `Tool.toDefinitions` in normal calls    | Named executable tool records                               |
+| Manual `ToolRuntime.dispatch` loop      | Automatic run dispatch; explicit turn API for orchestration |

+| `providerExecuted` dispatch check       | Distinct hosted-tool constructors                           |
+| One wrapped `LLMError`                  | Tagged domain error union                                   |
+
+OpenCode should migrate to `generateTurn` / `streamTurn`, preserving its durable
+prompt admission, persistence, permission, tool settlement, and continuation
+boundaries. It should not use the automatic run API for Session orchestration.
+
+## Remaining Implementation-level Questions
+
+These do not reopen the main design:
+
+1. Exact `RunEvent` and `TurnEvent` tag names and payloads
+2. Exact `GenerateResult` shortcut fields for text, reasoning, output, and messages
+3. Exact Provider definition TypeScript shape needed for strong inference
+4. Exact protocol `.with(...)` patch syntax and replacement semantics
+5. Exact Duration input fields and names
+6. Exact models.dev generation pipeline and correction-file format
+7. Exact cost representation and decimal arithmetic strategy
+8. Exact default retry schedule and bounded tool concurrency number
+9. Whether request-level serializable HTTP overlays belong in the stable schema
+10. Which tagged errors are serializable versus process-local
+
+These should be resolved with call-site sketches and implementation spikes rather
+than by changing the domain boundaries above.

-# Bun shell migration plan
-
-Practical phased replacement of Bun `$` calls.
-
-## Goal
-
-Replace runtime Bun shell template-tag usage in `packages/opencode/src` with a unified `Process` API in `util/process.ts`.
-
-Keep behavior stable while improving safety, testability, and observability.
-
-Current baseline from audit:
-
-- 143 runtime command invocations across 17 files
-- 84 are git commands
-- Largest hotspots:
-  - `src/cli/cmd/github.ts` (33)
-  - `src/worktree/index.ts` (22)
-  - `src/lsp/server.ts` (21)
-  - `src/installation/index.ts` (20)
-  - `src/snapshot/index.ts` (18)
-
-## Decisions
-
-- Extend `src/util/process.ts` (do not create a separate exec module).
-- Proceed with phased migration for both git and non-git paths.
-- Keep plugin `$` compatibility in 1.x and remove in 2.0.
-
-## Non-goals
-
-- Do not remove plugin `$` compatibility in this effort.
-- Do not redesign command semantics beyond what is needed to preserve behavior.
-
-## Constraints
-
-- Keep migration phased, not big-bang.
-- Minimize behavioral drift.
-- Keep these explicit shell-only exceptions:
-  - `src/session/prompt.ts` raw command execution
-  - worktree start scripts in `src/worktree/index.ts`
-
-## Process API proposal (`src/util/process.ts`)
-
-Add higher-level wrappers on top of current spawn support.
-
-Core methods:
-
-- `Process.run(cmd, opts)`
-- `Process.text(cmd, opts)`
-- `Process.lines(cmd, opts)`
-- `Process.status(cmd, opts)`
-- `Process.shell(command, opts)` for intentional shell execution
-
-Git helpers:
-
-- `Process.git(args, opts)`
-- `Process.gitText(args, opts)`
-
-Shared options:
-
-- `cwd`, `env`, `stdin`, `stdout`, `stderr`, `abort`, `timeout`, `kill`
-- `allowFailure` / non-throw mode
-- optional redaction + trace metadata
-
-Standard result shape:
-
-- `code`, `stdout`, `stderr`, `duration_ms`, `cmd`
-- helpers like `text()` and `arrayBuffer()` where useful
-
-## Phased rollout
-
-### Phase 0: Foundation
-
-- Implement Process wrappers in `src/util/process.ts`.
-- Refactor `src/util/git.ts` to use Process only.
-- Add tests for exit handling, timeout, abort, and output capture.
-
-### Phase 1: High-impact hotspots
-
-Migrate these first:
-
-- `src/cli/cmd/github.ts`
-- `src/worktree/index.ts`
-- `src/lsp/server.ts`
-- `src/installation/index.ts`
-- `src/snapshot/index.ts`
-
-Within each file, migrate git paths first where applicable.
-
-### Phase 2: Remaining git-heavy files
-
-Migrate git-centric call sites to `Process.git*` helpers:
-
-- `../core/src/filesystem.ts`
-- `src/project/vcs.ts`
-- `../core/src/filesystem/watcher.ts`
-- `src/storage/storage.ts`
-- `src/cli/cmd/pr.ts`
-
-### Phase 3: Remaining non-git files
-
-Migrate residual non-git usages:
-
-- `src/cli/cmd/tui/util/clipboard.ts`
-- `src/util/archive.ts`
-- `../core/src/filesystem/ripgrep.ts`
-- `src/tool/bash.ts`
-- `src/cli/cmd/uninstall.ts`
-
-### Phase 4: Stabilize
-
-- Remove dead wrappers and one-off patterns.
-- Keep plugin `$` compatibility isolated and documented as temporary.
-- Create linked 2.0 task for plugin `$` removal.
-
-## Validation strategy
-
-- Unit tests for new `Process` methods and options.
-- Integration tests on hotspot modules.
-- Smoke tests for install, snapshot, worktree, and GitHub flows.
-- Regression checks for output parsing behavior.
-
-## Risk mitigation
-
-- File-by-file PRs with small diffs.
-- Preserve behavior first, simplify second.
-- Keep shell-only exceptions explicit and documented.
-- Add consistent error shaping and logging at Process layer.
-
-## Definition of done
-
-- Runtime Bun `$` usage in `packages/opencode/src` is removed except:
-  - approved shell-only exceptions
-  - temporary plugin compatibility path (1.x)
-- Git paths use `Process.git*` consistently.
-- CI and targeted smoke tests pass.
-- 2.0 issue exists for plugin `$` removal.

 - Fast file pattern matching tool that works with any codebase size
 - Supports glob patterns like "**/*.js" or "src/**/*.ts"
-- Returns matching file paths sorted by modification time
+- Returns matching file paths
 - Use this tool when you need to find files by name patterns
 - When you are doing an open-ended search that may require multiple rounds of globbing and grepping, use the Task tool instead
 - You have the capability to call multiple tools in a single response. It is always better to speculatively perform multiple searches as a batch that are potentially useful.

-/**
- * Reproducer for opencode issue #26514:
- *
- * In Plan Mode (the `plan` agent), the main agent's edit/write tools are
- * blocked by the plan agent's permission ruleset (`edit: { "*": "deny" }`).
- * However, when the plan agent spawns a subagent via the `task` tool, the
- * subagent retains full file modification capabilities — a security bypass.
- *
- * This test replicates the permission ruleset that would govern a
- * `general` subagent when launched from a `plan` parent session, mirroring
- * the logic in `src/tool/task.ts` (filtered parent permissions ++ runtime
- * subagent agent permissions, evaluated as in `session/prompt.ts`).
- *
- * The expected (secure) behavior is that the subagent inherits the plan
- * mode read-only restriction and `edit`/`write` resolve to `deny`. On
- * origin/dev this assertion fails because the parent **agent** permissions
- * are not propagated to the subagent — only the parent **session**
- * permissions are passed through, and Plan Mode's restrictions live on the
- * agent, not the session.

+# V2 Plugin System Implementation Plan
+
+## Status
+
+This document describes the agreed target design for the V2 plugin system. It is an implementation plan, not documentation for the current API.
+
+## Goals
+
+- Internal and external plugins use the same public plugin API.
+- Effect plugins import `@opencode-ai/plugin/v2/effect`, not `@opencode-ai/core`.
+- Public domain values use generated `@opencode-ai/sdk` types.
+- Core may retain branded IDs, decoded Effect schemas, and internal service types.
+- Plugins may register replayable domain transforms and runtime hooks imperatively during setup.
+- Registrations are scoped, independently disposable, ordered, and removable.
+- Dynamic sources such as models.dev, config files, and skill directories can rebuild one domain without reloading the entire Location.
+- The initial implementation covers the Effect API. A Promise API will be designed afterward as a wrapper over the same capabilities.
+
+## Authoring Model
+
+A plugin setup effect receives `PluginHost` and imperatively registers transforms and hooks.
+
+```ts
+export const Plugin = define({
+  id: "example",
+  effect: (ctx) =>
+    Effect.gen(function* () {
+      yield* ctx.agent.transform(
+        Effect.fn(function* (agent) {
+          agent.update("reviewer", (item) => {
+            item.description = "Reviews code for regressions"
+            item.mode = "subagent"
+          })
+        }),
+      )
+
+      yield* ctx.tool.hook(
+        "execute.before",
+        Effect.fn(function* (event) {
+          event.args.update(sanitizeArgs)
+        }),
+      )
+    }),
+})
+```
+
+Plugin setup does not return hooks.
+
+## Public Naming
+
+Settled names:
+
+- Replayable domain registration: `transform`
+- Explicit domain replay: `rebuild`
+- Runtime callback registration: `hook`
+- Registration cleanup: `dispose`
+- Event domain: singular `event`
+- Other domains are singular: `agent`, `command`, `integration`, `reference`, `session`, `skill`, and `tool`; `catalog` remains `catalog`
+- Hook names use dotted lifecycle names such as `"execute.before"` and `"execute.after"`
+
+## Transform API
+
+Each transformable domain exposes:
+
+```ts
+interface TransformDomain<Editor> {
+  transform(callback: (editor: Editor) => Effect.Effect<void>): Effect.Effect<Registration, never, Scope.Scope>
+
+  rebuild(): Effect.Effect<void>
+}
+```
+
+The actual callback may be represented with the project's normal `Effect.fn` style.
+
+```ts
+const registration =
+  yield *
+  ctx.catalog.transform(
+    Effect.fn(function* (catalog) {
+      const integration = yield* ctx.integration.get("anthropic")
+      if (!integration) return
+
+      catalog.provider.update("anthropic", (provider) => {
+        provider.name = "Anthropic"
+      })
+    }),
+  )
+```
+
+Transforms may perform arbitrary Effects, including reads from other PluginHost services, filesystem I/O, and network I/O. Reads from another domain observe that domain's latest committed state.
+
+Transforms have no typed error channel. Unexpected failures are defects.
+
+## Transform Semantics
+
+- Every call to `transform()` creates an independent registration.
+- Multiple transforms from one plugin and domain are allowed.
+- Transform order is plugin registration order, then transform registration order within the plugin.
+- A transform is automatically removed when its registration scope closes.
+- `Registration.dispose` removes it early and is idempotent.
+- Registering or disposing a transform automatically rebuilds its domain.
+- During bulk plugin boot, automatic rebuilds are deferred and each affected domain is rebuilt once after the batch.
+- `rebuild()` waits until replay and finalization complete.
+- `rebuild()` always replays every active transform for the domain.
+- Rebuilds are serialized and coalesced. Calls arriving during an active rebuild schedule at most one additional rebuild.
+- A rebuild captures its registration list at the start. Concurrent registration changes affect the next rebuild.
+- Transforms may not register or dispose transforms while replaying. Such changes are rejected or deferred by the runtime.
+- Calling `rebuild()` for the currently rebuilding domain from one of its transforms is rejected.
+- Rebuilding another domain from a transform is deferred until the current transform finishes.
+
+## Registration API
+
+Transforms and runtime hooks return the same Effect registration type.
+
+```ts
+interface Registration {
+  readonly dispose: Effect.Effect<void>
+}
+```
+
+Registration behavior:
+
+- Automatically attached to the current `Scope.Scope`
+- Explicitly disposable before scope closure
+- Disposal affects future replays or invocations
+- An in-flight rebuild or hook invocation uses the registration snapshot captured when it started and is allowed to finish
+
+## Runtime Hook API
+
+Domains expose runtime interception through `hook()`.
+
+```ts
+const registration =
+  yield *
+  ctx.tool.hook(
+    "execute.before",
+    Effect.fn(function* (event) {
+      event.args.update(sanitizeArgs)
+    }),
+  )
+```
+
+Runtime hook behavior:
+
+- Multiple registrations for the same hook are allowed.
+- Hooks run sequentially in plugin and registration order.
+- Later hooks observe mutations made by earlier hooks.
+- Hook registration is scope-owned and independently disposable.
+- Disposal affects future invocations; an in-flight invocation finishes using its captured registration snapshot.
+- Runtime hooks are not replayed during domain rebuilds.
+- Runtime hook callbacks have no typed error channel.
+
+## Hook Contexts
+
+Each hook receives one purpose-built context object rather than separate input/output parameters.
+
+```ts
+ctx.tool.hook("execute.before", (event) => {
+  event.args.update((args) => ({
+    ...args,
+    timeout: 30,
+  }))
+})
+```
+
+Hook context objects may contain:
+
+- Readonly SDK-typed operation data
+- Purpose-built methods for allowed mutations
+- Capability methods where the operation requires more than field assignment
+
+They must not expose core drafts or unrestricted internal objects.
+
+## Domain Transforms Versus Runtime Hooks
+
+Both use the same low-level scoped registration registry, but consumers invoke them differently.
+
+```ts
+ctx.tool.transform(...) // replayed to build effective tool registry state
+ctx.tool.hook(...)      // invoked at a live tool operation boundary
+```
+
+The shared low-level machinery owns registration order, scope cleanup, disposal, and snapshots. Each domain owns when its transforms or runtime hooks execute.
+
+## Event API
+
+The Effect API exposes the existing event system as typed streams using generated SDK event discriminants.
+
+```ts
+ctx.event.subscribe("catalog.updated")
+// Stream.Stream<EventCatalogUpdated>
+```
+
+Example:
+
+```ts
+yield *
+  ctx.event.subscribe("catalog.updated").pipe(
+    Stream.runForEach(() => ctx.agent.rebuild()),
+    Effect.forkScoped,
+  )
+```
+
+The plugin package derives event payload types from the generated SDK `Event` union:
+
+```ts
+type EventMap = {
+  [Item in Event as Item["type"]]: Item
+}
+```
+
+Core resolves the public event type string to its internal event definition and delegates to `EventV2.Service.subscribe`.
+
+## Domain State Model
+
+Each transformable core service continues to own:
+
+- Base state
+- Effective committed state
+- Editor creation
+- Ordered transform registrations for that domain
+- Rebuild serialization and coalescing
+- Core finalization
+- Commit and post-commit events
+
+The initial implementation should evolve the existing generic `State` helper rather than create a central cross-domain state manager.
+
+```text
+base state
+→ replay active transforms in order
+→ core domain finalization
+→ commit effective state
+→ publish updated event
+```
+
+No cross-domain transform or transaction API is included.
+
+## Finalization
+
+Each domain has one plugin transform phase followed by core finalization.
+
+Core finalization is for invariants and materialization, not plugin extension behavior.
+
+Examples:
+
+- Catalog policy filtering and validation
+- Reference repository materialization
+- Integration connection projection
+- Index construction
+- Post-commit update events
+
+Finalizers should distinguish pre-commit work from post-commit notification. Update events should publish after the new state is visible.
+
+## Plugin Order
+
+The default distribution uses an opinionated internal order:
+
+```text
+1. Built-in agents, commands, and skills
+2. Base data sources such as models.dev
+3. Configuration projections
+4. Provider-specific normalization and authentication
+5. External user plugins
+6. Core domain finalization
+```
+
+For catalog transforms:
+
+```text
+models.dev
+→ config provider overrides
+→ built-in provider normalization
+→ user catalog transforms
+→ catalog finalization
+```
+
+This replaces the current distinction between setup-installed State transforms and catalog hooks invoked from the catalog finalizer.
+
+Replacing a plugin with the same ID retains its existing order position. The old plugin is disabled before the replacement setup starts.
+
+## Boot Batching
+
+Plugin boot runs in an internal registration batch.
+
+```text
+begin batch
+→ initialize plugins sequentially
+→ register transforms and hooks
+→ collect affected domains
+→ rebuild each affected domain once
+→ end batch
+```
+
+Registration itself is not staged per plugin. If setup fails, closing the plugin's child scope removes every registration made before the failure.
+
+Outside a batch, transform registration and disposal rebuild immediately.
+
+## Models.dev Example
+
+Models.dev performs effectful reads directly from its transforms and rebuilds affected domains after refresh.
+
+```ts
+export const ModelsDevPlugin = define({
+  id: "models-dev",
+  effect: (ctx) =>
+    Effect.gen(function* () {
+      const modelsDev = yield* ModelsDev.Service
+      const event = yield* EventV2.Service
+
+      yield* ctx.integration.transform(
+        Effect.fn(function* (integration) {
+          const data = yield* modelsDev.get()
+          applyIntegrations(data, integration)
+        }),
+      )
+
+      yield* ctx.catalog.transform(
+        Effect.fn(function* (catalog) {
+          const data = yield* modelsDev.get()
+          applyCatalog(data, catalog)
+        }),
+      )
+
+      yield* event.subscribe(ModelsDev.Event.Refreshed).pipe(
+        Stream.runForEach(
+          Effect.fn(function* () {
+            yield* ctx.integration.rebuild()
+            yield* ctx.catalog.rebuild()
+          }),
+        ),
+        Effect.forkScoped({ startImmediately: true }),
+      )
+    }),
+})
+```
+
+The two domains rebuild sequentially. This plan does not add a cross-domain atomic transaction.
+
+## Config Watcher Example
+
+```ts
+export const ConfigPlugin = define({
+  id: "config",
+  effect: (ctx) =>
+    Effect.gen(function* () {
+      const config = yield* ConfigSource.Service
+
+      yield* ctx.agent.transform(
+        Effect.fn(function* (agent) {
+          applyAgentConfig(yield* config.get(), agent)
+        }),
+      )
+
+      yield* ctx.command.transform(
+        Effect.fn(function* (command) {
+          applyCommandConfig(yield* config.get(), command)
+        }),
+      )
+
+      yield* config.changes.pipe(
+        Stream.runForEach(
+          Effect.fn(function* () {
+            yield* ctx.agent.rebuild()
+            yield* ctx.command.rebuild()
+          }),
+        ),
+        Effect.forkScoped,
+      )
+    }),
+})
+```
+
+## Cross-Domain Read Example
+
+A transform may read another committed service. It must still arrange for its own domain to rebuild when that dependency changes.
+
+```ts
+export const AnthropicAgentPlugin = define({
+  id: "anthropic-agent",
+  effect: (ctx) =>
+    Effect.gen(function* () {
+      yield* ctx.agent.transform(
+        Effect.fn(function* (agent) {
+          const providers = yield* ctx.catalog.provider.list()
+          if (!providers.some((provider) => provider.id === "anthropic")) return
+
+          agent.update("anthropic-reviewer", (item) => {
+            item.description = "Reviews code using Anthropic"
+            item.mode = "subagent"
+            item.model = {
+              providerID: "anthropic",
+              id: "claude-sonnet",
+            }
+          })
+        }),
+      )
+
+      yield* ctx.event.subscribe("catalog.updated").pipe(
+        Stream.runForEach(() => ctx.agent.rebuild()),
+        Effect.forkScoped,
+      )
+    }),
+})
+```
+
+The runtime does not infer cross-domain dependencies.
+
+## Embedding API Compatibility
+
+The imperative registration model maps naturally to a future application embedding API:
+
+```ts
+const registration = oc.agent.transform((agent) => {
+  agent.update("reviewer", configureReviewer)
+})
+
+registration.dispose()
+```
+
+An application registration is stored as an application-level plugin registration. It attaches to every current Location and is installed during future Location boot. Disposal removes all current attachments and prevents future attachment.
+
+The Effect implementation remains the canonical runtime. Promise and embedding wrappers are deferred until after the Effect API is stable.
+
+## Migration Plan
+
+### 1. Define Public Contracts
+
+- Define `PluginHost` domain capabilities in `@opencode-ai/plugin/v2/effect`.
+- Define SDK-typed editors for agent, catalog, command, integration, reference, skill, and tool.
+- Define typed runtime hook maps per domain.
+- Define `Registration`.
+- Define typed `event.subscribe(type)`.
+
+### 2. Generalize Registration Machinery
+
+- Add one low-level scoped registration registry used by transforms and runtime hooks.
+- Preserve plugin order and registration order.
+- Support idempotent disposal and registration snapshots.
+- Retain plugin position during same-ID replacement.
+
+### 3. Evolve State
+
+- Replace the current returned transform-slot updater with direct `transform(callback)` registration.
+- Support Effectful callbacks.
+- Add public `rebuild()`.
+- Add rebuild serialization and coalescing.
+- Add boot batching that defers automatic rebuilds.
+- Move update event publication after commit.
+
+### 4. Expand Domain Transform Hooks
+
+- Agent
+- Catalog
+- Command
+- Integration
+- Reference
+- Skill
+- Tool
+
+### 5. Migrate Existing Plugins
+
+- Built-in agent transform
+- Built-in command transform
+- Built-in skill transform
+- Models.dev catalog and integration transforms
+- Config transforms
+- OpenAI integration transform
+- Provider catalog transforms
+
+### 6. Migrate Runtime Hooks
+
+- AI SDK resolution
+- Language model resolution
+- Tool execution hooks
+- Session prompt/context hooks as required
+
+### 7. Remove Returned Hooks
+
+- Remove `HookFunctions` as the plugin setup return value.
+- Remove catalog's special finalizer-triggered plugin hook path.
+- Remove `plugin.added` catalog mutation handling.
+- Make add/remove/replacement rely on scoped registration and domain rebuilds.
+
+### 8. Add Event Adapter
+
+- Build the SDK event discriminant map.
+- Resolve public type strings to internal EventV2 definitions.
+- Return typed Effect streams.
+
+### 9. Verification
+
+- Transform order is deterministic.
+- Multiple transforms per plugin/domain compose.
+- Registration and disposal rebuild automatically outside boot batches.
+- Boot performs one rebuild per affected domain.
+- Plugin setup failure removes prior registrations.
+- Same-ID replacement retains order and disables the old plugin first.
+- Rebuilds serialize and coalesce.
+- Registration changes during replay affect the next rebuild.
+- Same-domain recursive rebuild is rejected.
+- Cross-domain rebuild requests from transforms are deferred.
+- Hook execution is sequential and snapshot-based.
+- Models.dev refresh replays config and provider transforms.
+- Config and skill watcher refreshes remove stale entries.
+- Plugin removal restores prior effective state.
+- Events observe newly committed state.
+
+## Deferred Decisions
+
+- Promise API shape
+- Typed error model
+- Transform timeouts
+- Cross-domain atomic rebuilds
+- Automatic dependency tracking
+- Whole-Location generation reload
+- Exact editors and runtime hooks not required by current plugins

+# OpenCode V2 Effect Plugin API
+
+The Effect plugin API grants plugins two in-process capabilities:
+
+- `hook` installs behavior at an OpenCode extension point.
+- `reload` reruns every transform hook for a stateful domain.
+
+The public server client will be exposed separately. It is intentionally not part of `PluginContext` yet.
+
+## Defining A Plugin
+
+```ts
+import { define } from "@opencode-ai/plugin/v2/effect"
+import { Effect } from "effect"
+
+export const Plugin = define({
+  id: "example",
+  effect: Effect.fn(function* (ctx) {
+    yield* ctx.catalog.transform((catalog) => {
+      catalog.provider.update("example", (provider) => {
+        provider.name = "Example"
+      })
+    })
+  }),
+})
+```
+
+Plugin setup registers hooks imperatively. It does not return a hook object.
+
+Configuration supplied for the plugin is available as `ctx.options`.
+
+Registrations are owned by the plugin scope. Closing the scope removes them automatically; a registration may also be removed early through `dispose`.
+
+## Transform Hooks
+
+Transform hooks contribute to stateful domains:
+
+```ts
+yield *
+  ctx.agent.transform((agent) => {
+    agent.update("reviewer", (item) => {
+      item.description = "Reviews code for regressions"
+      item.mode = "subagent"
+    })
+  })
+```
+
+OpenCode rebuilds the domain when a transform is registered or disposed. A rebuild starts from fresh domain state and runs every active transform in registration order.
+
+Available transform hooks are namespaced by domain:
+
+```ts
+ctx.agent.transform
+ctx.catalog.transform
+ctx.command.transform
+ctx.integration.transform
+ctx.reference.transform
+ctx.skill.transform
+```
+
+## Runtime Hooks
+
+Runtime hooks intercept live operations rather than rebuilding domain state:
+
+```ts
+yield *
+  ctx.aisdk.sdk(
+    Effect.fn(function* (event) {
+      if (event.package !== "@ai-sdk/xai") return
+      const mod = yield* Effect.promise(() => import("@ai-sdk/xai"))
+      event.sdk = mod.createXai(event.options)
+    }),
+  )
+
+yield *
+  ctx.aisdk.language((event) => {
+    if (event.model.providerID !== "xai") return
+    event.language = event.sdk.responses(event.model.api.id)
+  })
+```
+
+Hooks run sequentially in registration order. Later hooks observe mutations made by earlier hooks.
+
+## Reloading A Domain
+
+When data captured by a transform changes, reload the affected domain:
+
+```ts
+let data = yield * loadCatalog()
+
+yield *
+  ctx.catalog.transform((catalog) => {
+    applyCatalog(data, catalog)
+  })
+
+data = yield * loadCatalog()
+yield * ctx.catalog.reload()
+```
+
+Reload belongs to the domain, not an individual registration. `ctx.catalog.reload()` reruns every active catalog transform and publishes the rebuilt catalog.
+
+Available reload operations are:
+
+```ts
+ctx.agent.reload()
+ctx.catalog.reload()
+ctx.command.reload()
+ctx.integration.reload()
+ctx.reference.reload()
+ctx.skill.reload()
+```

+# OpenCode V2 Promise Plugin API
+
+The Promise plugin API is the async/await equivalent of `@opencode-ai/plugin/v2/effect`. It grants plugins the same two in-process capabilities:
+
+- `hook` installs behavior at an OpenCode extension point.
+- `reload` reruns every transform hook for a stateful domain.
+
+The only difference from the Effect API is the async boundary: hook callbacks, hook registration, `reload`, and `Registration.dispose` use Promises instead of Effects.
+
+## Defining A Plugin
+
+```ts
+import { define } from "@opencode-ai/plugin/v2/promise"
+
+export const Plugin = define({
+  id: "example",
+  setup: async (ctx) => {
+    await ctx.catalog.transform((catalog) => {
+      catalog.provider.update("example", (provider) => {
+        provider.name = "Example"
+      })
+    })
+  },
+})
+```
+
+Plugin setup registers hooks imperatively. It does not return a hook object.
+
+Configuration supplied for the plugin is available as `ctx.options`.
+
+A registration may be removed early through `dispose`:
+
+```ts
+const registration = await ctx.catalog.transform(applyCatalog)
+await registration.dispose()
+```
+
+## Transform Hooks
+
+Transform hooks contribute to stateful domains. The draft editor is synchronous; the callback may be `async` when it needs to await other work:
+
+```ts
+await ctx.agent.transform((agent) => {
+  agent.update("reviewer", (item) => {
+    item.description = "Reviews code for regressions"
+    item.mode = "subagent"
+  })
+})
+```
+
+Available transform hooks are namespaced by domain:
+
+```ts
+ctx.agent.transform
+ctx.catalog.transform
+ctx.command.transform
+ctx.integration.transform
+ctx.reference.transform
+ctx.skill.transform
+```
+
+## Runtime Hooks
+
+Runtime hooks intercept live operations:
+
+```ts
+await ctx.aisdk.sdk(async (event) => {
+  if (event.package !== "@ai-sdk/xai") return
+  const mod = await import("@ai-sdk/xai")
+  event.sdk = mod.createXai(event.options)
+})
+
+await ctx.aisdk.language((event) => {
+  if (event.model.providerID !== "xai") return
+  event.language = event.sdk.responses(event.model.api.id)
+})
+```
+
+## Reloading A Domain
+
+When data captured by a transform changes, reload the affected domain:
+
+```ts
+let data = await loadCatalog()
+
+await ctx.catalog.transform((catalog) => {
+  applyCatalog(data, catalog)
+})
+
+data = await loadCatalog()
+await ctx.catalog.reload()
+```
+
+Available reload operations are:
+
+```ts
+ctx.agent.reload()
+ctx.catalog.reload()
+ctx.command.reload()
+ctx.integration.reload()
+ctx.reference.reload()
+ctx.skill.reload()
+```

+# @opencode-ai/sdk-next
+
+Effect-native scoped OpenCode host for in-process applications. This transitional package will replace the existing generated `@opencode-ai/sdk` after its consumers migrate.
+
+The SDK executes Server's assembled HTTP router in memory. It opens no listener and performs no network I/O, while preserving the same routing, middleware, handlers, codecs, and errors as the network client.
+
+```ts
+import { OpenCode } from "@opencode-ai/sdk-next"
+
+const opencode = yield * OpenCode.create()
+const session = yield * opencode.sessions.get({ sessionID })
+```
+
+It also exposes local-only `tools.register(...)`. Closing the owning Effect Scope releases router resources, location services, fibers, and scoped tool registrations.
+
+The same constructor is available as a service Layer:
+
+```ts
+const program = Effect.gen(function* () {
+  const opencode = yield* OpenCode.Service
+  return yield* opencode.sessions.get({ sessionID })
+})
+
+yield * program.pipe(Effect.provide(OpenCode.layer))
+```
+
+`OpenCode.layer` adapts `OpenCode.create()` for dependency injection; it does not define another host implementation.

+Animated 5×5 dot grid loader for in-progress session state.

+Derived from Figma \`_sessionProgressIndicator\` with 8-frame rotation.
+
+### API
+- Accepts standard SVG props.
+
+### Behavior
+- CSS keyframes drive per-dot opacity across 8 frames (1.2s loop).
+- Center dot stays at full opacity throughout the cycle.
+
+### Accessibility
+- Sets \`aria-hidden="true"\` by default.
+
+### Theming
+- Uses \`currentColor\` via \`--v2-icon-icon-muted\`.

+### Snowflake Cortex
+
+[Snowflake Cortex](https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-rest-api) gives you access to frontier models (Claude, OpenAI GPT-5, and more) via an OpenAI-compatible API. All inference runs within the Snowflake perimeter and is billed in Snowflake credits. For per-model rates, see the [Snowflake Service Consumption Table](https://www.snowflake.com/legal-files/CreditConsumptionTable.pdf).
+
+Don't have a Snowflake account? [Sign up for a free trial](https://signup.snowflake.com/?utm_source=opencode&utm_medium=docs&utm_campaign=cortex-provider).
+
+opencode's core workflow for coding, editing files, and running commands relies on tool calling. Only the Claude and OpenAI families within Snowflake Cortex support this. The provider is limited to those families to support the core workflow.
+
+OpenCode supports two authentication methods:
+
+- **Browser OAuth (Recommended)** — sign in with your IdP/SSO; no secrets to manage, tokens refresh automatically.
+- **Manual bearer token** — paste a PAT or JWT from the Snowflake console.
+
+#### Browser OAuth (Recommended)
+
+1. Run the `/connect` command and search for **Snowflake Cortex**.
+
+   ```txt
+   /connect
+   ```
+
+2. Select **Login with Snowflake (External Browser)**.
+
+   ```txt
+   ┌ Select auth method
+   │
+   │ Login with Snowflake (External Browser)
+   │ Paste PAT or bearer token manually
+   └
+   ```
+
+3. Enter your [account identifier](https://docs.snowflake.com/en/user-guide/admin-account-identifier) when prompted, for example `myorg-myaccount` or `xy12345.us-east-1`.
+
+   ```txt
+   ┌ Snowflake Account Identifier
+   │
+   │
+   └ enter
+   ```
+
+4. Optionally enter a Snowflake role to scope the session (e.g. `SYSADMIN`). Leave blank to use your default role.
+
+5. Complete sign-in in the browser that opens. OpenCode captures the OAuth callback automatically and stores the token — no copy/paste needed.
+
+6. Run the `/models` command to select a model.
+
+   ```txt
+   /models
+   ```
+
+:::note
+Browser OAuth uses Snowflake's built-in `SNOWFLAKE$LOCAL_APPLICATION` security integration ([docs](https://docs.snowflake.com/en/user-guide/oauth-local-applications)), which is rolling out to all accounts. To check availability in your account:
+
+```sql
+SHOW SECURITY INTEGRATIONS LIKE 'SNOWFLAKE$LOCAL_APPLICATION';
+```
+
+If the result is empty, use the **Manual bearer token** method below while the integration rolls out to your account.
+:::
+
+#### Manual bearer token
+
+If you prefer to paste a token directly, or if `SNOWFLAKE$LOCAL_APPLICATION` is not yet available in your account:
+
+1. Generate a [Programmatic Access Token (PAT)](https://docs.snowflake.com/en/user-guide/programmatic-access-tokens) in your Snowflake account.
+
+2. Run the `/connect` command, search for **Snowflake Cortex**, and select **Paste PAT or bearer token manually**.
+
+3. Enter your [account identifier](https://docs.snowflake.com/en/user-guide/admin-account-identifier) when prompted.
+
+4. Paste your PAT.
+
+5. Run the `/models` command to select a model.
+
+   ```txt
+   /models
+   ```
+
+#### Environment variable
+
+For CI or headless environments, set a PAT or JWT before starting opencode:
+
+```bash
+export SNOWFLAKE_ACCOUNT=myorg-myaccount
+export SNOWFLAKE_CORTEX_TOKEN=your-pat-or-jwt
+```
+
+:::note
+`SNOWFLAKE_CORTEX_TOKEN` accepts a PAT or JWT only — the browser OAuth flow is available via `/connect` only and cannot be configured through an environment variable. `SNOWFLAKE_CORTEX_PAT` is still supported for backward compatibility.
+:::
+
+The model catalog is provided automatically. A minimal `opencode.json` is all that's needed:
+
+```json title="opencode.json"
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "snowflake-cortex/claude-sonnet-4-6",
+  "small_model": "snowflake-cortex/claude-haiku-4-5"

+```jsonc title="opencode.jsonc"
+{
+  "references": {
+    "docs": {
+      "path": "../docs",
+    },
+  },
+}
+```
+
+Paths can be:
+
+- Relative to the config file that defines the reference
+- Absolute, such as `/home/user/docs`
+- Relative to your home directory, such as `~/docs`
+
+You can also use a string shorthand:
+
+```jsonc title="opencode.jsonc"
+{
+  "references": {
+    "docs": "../docs",
+  },
+}
+```
+
+---
+
+## Git repositories
+
+Use `repository` to reference a Git repository. OpenCode materializes the repository in its local repository cache and makes the checked-out source available as a reference directory.
+
+```jsonc title="opencode.jsonc"
+{
+  "references": {
+    "effect": {
+      "repository": "Effect-TS/effect",
+      "branch": "main",
+    },
+  },
+}
+```
+
+`repository` accepts Git URLs, host/path references, and GitHub `owner/repo` shorthand. The optional `branch` field selects a branch or ref. Without `branch`, OpenCode uses the repository's default branch.
+
+You can use string shorthand when you do not need a branch, description, or other options:
+
+```jsonc title="opencode.jsonc"
+{
+  "references": {
+    "effect": "Effect-TS/effect",
+  },
+}
+```
+
+:::note
+Git references are refreshed asynchronously. A newly configured repository may take a moment to finish cloning or updating.
+:::
+
+---
+
+## Describe usage
+
+Add `description` to explain when an agent should use a reference.
+
+```jsonc title="opencode.jsonc"
+{
+  "references": {
+    "design-system": {
+      "path": "../design-system",
+      "description": "Use when implementing UI components or design tokens",
+    },
+  },
+}
+```
+
+OpenCode includes references with descriptions in agent context. Descriptions should be short and specific enough to distinguish references with similar content. References without descriptions remain available through autocomplete and direct use, but are not advertised to agents.
+
+---
+
+## Hide autocomplete entries
+
+Set `hidden` to `true` to omit a reference from `@` autocomplete in the TUI.
+
+```jsonc title="opencode.jsonc"
+{
+  "references": {
+    "internal": {
+      "path": "../internal",
+      "description": "Use for internal implementation details",
+      "hidden": true,
+    },
+  },
+}
+```
+
+`hidden` only affects autocomplete. A hidden reference with a description remains included in agent context.
+
+---
+
+## Use references
+
+Configured references appear in TUI `@` autocomplete. Type `@alias` to attach the reference root, or `@alias/` to search for files inside it.
+
+```text
+Compare this implementation with @sdk/src/client.ts
+```
+
+Agents also receive the resolved paths and descriptions of configured references that have descriptions in their system context, so they can inspect a reference when it is relevant without you attaching it manually.
+
+OpenCode automatically allows reference directories through its external-directory permission boundary. Normal tool permissions still apply; for example, an agent that cannot edit files does not gain edit access because a directory is configured as a reference.
+
+---
+

+# TUI Package Extraction
+
+## Goal
+
+Move the canonical OpenCode terminal application from
+`packages/opencode/src/cli/cmd/tui` into a self-contained workspace package while
+the legacy CLI and the new CLI continue to use the same implementation.
+
+Target package:
+
+```text
+packages/tui
+name: @opencode-ai/tui
+```
+
+Target dependency graph:
+
+```text
+packages/opencode ---\
+                      > @opencode-ai/tui -> @opencode-ai/sdk
+packages/cli --------/
+```
+
+The TUI may directly depend on terminal and UI infrastructure such as
+`@opentui/core`, `@opentui/solid`, `@opentui/keymap`, `solid-js`, Effect, and
+generic presentation libraries. It must not depend on `packages/opencode`,
+`packages/cli`, or `@opencode-ai/core`.
+
+The SDK is the TUI's OpenCode boundary. Missing backend data or operations must
+be added to the server API and generated SDK rather than imported from backend
+implementation modules.
+
+## Migration Rules
+
+- Keep one canonical implementation of every TUI feature. Do not copy the full
+  TUI into `packages/cli` and synchronize two trees.
+- Land each section below independently and commit it before starting the next
+  section.
+- Keep each intermediate commit buildable and type-safe.
+- Continue integrating team changes into whichever location is canonical for a
+  file at that point in the migration.
+- Use temporary compatibility re-exports only when they materially reduce the
+  size or conflict risk of a section. Mark them for removal in a later section.
+- Do not preserve private imports by creating aliases from `packages/tui` back
+  into `packages/opencode`.
+- Do not replace private `packages/opencode` imports with `@opencode-ai/core`
+  imports merely to make the package compile.
+- Keep tool rendering tolerant of unknown tools and wire-format changes. Local
+  checks over `unknown` input and metadata are acceptable; importing backend
+  tool implementations for type safety is not.
+- Keep legacy CLI command parsing, server startup, worker management,
+  authentication, and config discovery outside `@opencode-ai/tui`.
+
+## Ownership Boundary
+
+### `@opencode-ai/tui` Owns
+
+- OpenTUI renderer lifecycle shared by both CLI hosts
+- Solid application composition
+- Components, routes, dialogs, themes, keymaps, and UI primitives
+- SDK client synchronization and event consumption
+- Tool-call and tool-result presentation
+- TUI-facing plugin contracts and presentation slots
+- Resolved TUI configuration types, defaults, and pure validation
+- Terminal behavior such as selection, clipboard integration, and local editor
+  launching when it is not host-specific
+- TUI-local persistence such as prompt history, stash, frecency, selected model,
+  and selected theme
+- Presentation utilities such as locale formatting, error display, record
+  checks, duration formatting, and layout helpers
+
+### CLI Hosts Own
+
+- Command definitions and argument parsing
+- Starting, locating, and stopping servers and workers
+- Authentication and transport construction
+- Process-level signal policy
+- Config file discovery, precedence, migration, and environment substitution
+- Plugin package discovery, installation, and backend activation
+- Upgrade checks and installation metadata
+- Executable build wiring and worker path defines
+
+### Server And SDK Own
+
+- OpenCode domain data displayed by the TUI
+- Session, message, workspace, file, provider, model, agent, and permission
+  operations
+- Retry, revert, fork, share, and other backend actions
+- Stable wire shapes for tool parts and plugin metadata
+- Server capabilities needed to conditionally expose UI behavior
+
+## Current Boundary
+
+The canonical implementation currently lives under:
+
+```text
+packages/opencode/src/cli/cmd/tui
+```
+
+Its private dependency on `packages/opencode` is primarily expressed through
+the `@/*` TypeScript alias, which resolves to `packages/opencode/src/*`.
+`@tui/*` imports are internal to the TUI and are not themselves a package
+boundary problem.
+
+The main private dependency groups are:
+
+- `@/util/*`: presentation helpers plus filesystem/process/RPC helpers
+- `@/tool/*`: backend tool implementations used by renderers
+- `@/session/*`, `@/provider/*`, and `@/reference/*`: backend data and actions
+- `@/config/*`: config discovery, parsing, variables, and plugin resolution
+- `@/plugin/*`: plugin loading and installation
+- `@/cli/*`: yargs adapters, network setup, errors, and CLI presentation
+- `@/server/*`: authentication and embedded server behavior
+- `Global.Path`, `Flag`, and process environment reads
+
+The initial extraction should reduce these dependencies in place before moving
+the application root.
+
+## Section 1: Create The Package Skeleton
+
+Status: Completed. The private `@opencode-ai/tui` workspace package now has an
+independent OpenTUI Solid JSX configuration, narrow root export, package-local
+alias, and in-memory render smoke test. Neither CLI consumes the package yet.
+
+Create `packages/tui` without moving the application root yet.
+
+Tasks:
+
+- Add `packages/tui/package.json` with the name `@opencode-ai/tui`.
+- Add a package `tsconfig.json` configured for OpenTUI Solid JSX.
+- Add `bunfig.toml` with the OpenTUI Solid preload for package-local development

+## Section 2: Move Presentation Utilities And Leaf UI
+
+Status: Completed. Presentation utilities, bundled themes and their pure theme
+engine, keybinding/keymap mechanics, and low-coupling border, link, and spinner
+primitives now live in `@opencode-ai/tui`. The legacy host consumes explicit
+package exports and retains only integration wrappers or compatibility
+re-exports where backend and process concerns have not moved yet.
+
+Move low-coupling code first so subsequent team changes land in the new package
+without waiting for the application root migration.
+
+Tasks:
+
+- Move TUI presentation utilities into `packages/tui/src/util`, including the
+  portions of locale, error display, record checks, duration formatting, and
+  small functional helpers used by TUI code.
+- Move pure TUI utilities already under the old TUI directory.
+- Move themes and bundled theme JSON files.
+- Move UI primitives and leaf components that have no private backend imports.
+- Move pure keybinding schemas and keymap helpers that do not read host flags.
+- Move related unit and snapshot tests.
+- Update remaining old-tree consumers to import the new canonical modules.
+- Use temporary compatibility re-exports from old TUI paths only if needed to
+  avoid a large unrelated import rewrite.
+- Do not move `Filesystem`, `Process`, `Rpc`, worker startup, or config discovery
+  as generic utilities in this section.
+
+Exit criteria:
+
+- Moved files have no `@/...` imports.
+- Tests for moved code run from `packages/tui`.
+- Existing legacy TUI behavior and typecheck remain unchanged.

+
+## Section 3: Remove Backend Tool Implementation Imports
+
+Status: Completed. Legacy and V2 tool renderers now dispatch on SDK wire names,
+accept `Record<string, unknown>` input and metadata, and use local guards for
+nested presentation data. Web-search labels and structured metadata extraction
+are TUI-owned, unknown tools retain the generic fallback, and no TUI source
+imports backend tool implementations. The route components remain in the legacy
+tree until the SDK state and route move in Section 6.
+
+Make tool rendering depend only on SDK wire data and local presentation logic.
+
+Tasks:
+
+- Remove imports from `@/tool/*` in TUI routes and feature plugins.
+- Key built-in renderers by SDK tool name strings such as `read`, `write`,
+  `edit`, `apply_patch`, `grep`, `glob`, `bash`, `question`, and `task`.
+- Treat tool input, output metadata, and plugin-defined fields as `unknown` at
+  the package boundary.
+- Add small local type guards only where a renderer needs a particular field.
+- Preserve a generic fallback renderer for unknown and plugin-provided tools.
+- Keep renderer failures local: malformed metadata must not crash the entire
+  session view.
+- Replace backend-derived labels or IDs with TUI-owned presentation constants or
+  SDK-provided values.
+- Move the affected tool presentation components and tests to `packages/tui`.
+
+Exit criteria:
+
+- No TUI source imports `@/tool/*`.
+- Unknown tools render through the generic fallback.
+- Existing built-in tool snapshots remain equivalent unless intentionally
+  updated and reviewed.

+## Section 4: Make Runtime Inputs Explicit
+
+Status: Completed for the shared runtime contract and legacy host. The TUI now
+receives immutable launch-directory, path, capability, terminal/editor, startup,
+and build inputs through `@opencode-ai/tui/runtime`. Movable app, component,
+route, and feature-plugin code no longer reads OpenCode globals or process state;
+command, config, plugin-loading, custom-theme discovery, editor/clipboard, and
+Windows lifecycle adapters remain host-owned. `packages/cli` does not consume
+this contract yet; that integration remains deferred to Section 9.
+
+Replace process-global OpenCode state with resolved TUI inputs.
+
+Define narrow inputs rather than one unstructured host object. Expected groups
+include:
+
+```ts
+type TuiCapabilities = {
+  mouse: boolean
+  copyOnSelect: boolean
+  terminalTitle: boolean
+  workspaces: boolean
+  showTimeToFirstDraw: boolean
+}
+
+type TuiPaths = {
+  home: string
+  state: string
+  config: string
+  data: string
+}
+
+type TuiBuildInfo = {
+  version: string
+  channel?: string
+}
+```
+
+Tasks:
+
+- Inventory direct reads of `Flag`, `Global.Path`, and relevant environment
+  variables in movable TUI code.
+- Pass resolved capabilities into the application/provider tree.
+- Pass local path roots or a narrow TUI storage capability into persistence
+  contexts.
+- Pass build/version information explicitly.
+- Keep environment reads needed by legacy command or worker startup in
+  `packages/opencode` adapters.
+- Give `packages/tui` sensible host-neutral defaults only when behavior is truly
+  local to a terminal client.
+- Move contexts and components after their global dependencies are removed.
+
+Exit criteria:
+
+- Movable TUI code does not import `Flag` or `Global`.
+- TUI tests can supply deterministic capabilities and storage paths.
+- The legacy host constructs the required input through the public package API;
+  the new CLI integration remains deferred to Section 9.

+
+## Section 5: Separate Resolved TUI Config From Host Config Loading
+
+Status: Completed for the package config contract and legacy host adapter.
+`@opencode-ai/tui/config` now owns schemas, defaults, keybind resolution, the
+resolved config type, and the Solid config provider. The legacy host retains
+file discovery, precedence, JSONC parsing, substitutions, migration,
+source-relative sound paths, plugin origins, dependency installation, and
+Effect services. `packages/cli` remains untouched until Section 9.
+
+Move config semantics needed by rendering while retaining filesystem discovery
+and migration in the legacy host.
+
+Tasks:
+
+- Move TUI config schemas, keybind schemas, defaults, and pure resolution to
+  `packages/tui`.
+- Define the resolved config accepted by the public TUI entrypoint.
+- Keep config path discovery, project/global precedence, migration, variable
+  expansion, and plugin package installation in `packages/opencode` initially.
+- Make the legacy host produce the same resolved config shape.
+- Add a new CLI adapter that can initially provide defaults or its own resolved
+  configuration.
+- Update schema-generation imports to use the package's explicit config export
+  if schema generation still needs TUI schemas.
+- Move pure config tests; retain discovery and migration integration tests in
+  `packages/opencode`.
+
+Exit criteria:
+
+- `packages/tui` does not import `@/config/*`.
+- Config discovery can change without changing TUI rendering code.
+- The old CLI still honors existing config precedence and migration behavior.

+
+## Section 6: Move SDK State, Routes, And Backend Operations
+
+Status: Completed for the SDK/domain boundary. SDK, project, event, legacy sync,
+V2 sync, local model state, prompt persistence, and pure prompt helpers are now
+canonical in `@opencode-ai/tui`. Configured references resolve through the new
+generated `reference.list` SDK operation; prompt payloads rely on optional
+server-assigned IDs; local attachment reads use the package platform contract.
+Legacy route files remain in place until the plugin slot boundary and app-root
+move, but their only private dependencies are plugin presentation or local host
+adapters rather than OpenCode domain implementations.
+
+Make the SDK the only OpenCode domain boundary used by the TUI.
+
+Tasks:
+
+- Move SDK client providers, event synchronization, routes, prompt UI, and
+  session views into `packages/tui`.
+- Replace direct imports from `@/session/*`, `@/provider/*`, `@/reference/*`,
+  `@/lsp/*`, and other backend domains with SDK data or TUI-owned presentation
+  helpers.
+- Replace direct backend actions such as retry with SDK calls.
+- For each missing operation, add or adjust the server endpoint, regenerate the
+  JavaScript SDK with `./packages/sdk/js/script/build.ts`, and consume the
+  generated SDK API.
+- Keep transport creation outside the package. Accept a base URL, headers,
+  custom fetch, event source, or constructed SDK client as appropriate.
+- Keep local-only UI state in the TUI package rather than adding it to the
+  server API.
+- Move affected tests and fixtures. Use real SDK/server integration where
+  practical instead of mocking backend modules.
+
+Exit criteria:
+
+- Domain-facing TUI code imports OpenCode data and operations only from
+  `@opencode-ai/sdk`.
+- No TUI source imports private session, provider, reference, LSP, server, or
+  core domain implementations.
+- SDK generation is clean after any API changes.

+## Section 7: Isolate Plugin Presentation From Plugin Loading
+
+Status: Completed. Plugin slots, route registration, TUI-facing APIs, runtime
+presentation state, and built-in feature plugins now live in
+`@opencode-ai/tui`. The legacy host injects a narrow plugin host that retains
+discovery, installation, manifest/config mutation, external module execution,
+pure-mode filtering, and cleanup ownership. Missing or failing plugin hosts
+degrade to the base TUI without blocking startup.
+
+Keep plugin UI extensibility without importing the legacy plugin installer and
+loader into the TUI package.
+
+Tasks:
+
+- Move plugin presentation slots, route contracts, and TUI-facing APIs into
+  `packages/tui` or the existing public plugin TUI contract package.
+- Keep package discovery, installation, manifest resolution, backend activation,
+  and process lifecycle in the host.
+- Define the serialized or runtime plugin presentation data the TUI requires.
+- Prefer SDK-delivered plugin metadata when the behavior must also work for a
+  remote server.
+- Make plugin absence or incompatibility degrade gracefully.
+- Move plugin rendering tests to `packages/tui`; retain installation/loading
+  integration tests in `packages/opencode`.
+
+Exit criteria:
+
+- `packages/tui` does not import `@/plugin/*` or the old TUI plugin runtime.
+- Remote and local TUI clients have a defined plugin behavior.
+- Plugin UI failures cannot prevent the base TUI from starting.

+
+## Section 8: Move The Application Root And Renderer Lifecycle
+
+Status: Completed. `packages/tui` now owns the canonical application root,
+provider composition, routes, components, parser presentation, renderer
+configuration, and renderer lifecycle. Process mutation, Windows console
+handling, backend worker startup, config loading, plugin loading, native audio,
+and legacy platform implementations remain injected host adapters. Old source
+paths are temporary compatibility re-exports for the legacy command host.
+
+Move the canonical app composition after its dependencies have already crossed
+the package boundary.
+
+Tasks:
+
+- Move `app.tsx`, remaining providers, routes, components, attention handling,
+  keymaps, and renderer lifecycle to `packages/tui`.
+- Export a narrow public API such as:
+
+```ts
+export type TuiInput = {
+  url: string
+  directory?: string
+  headers?: RequestInit["headers"]
+  fetch?: typeof fetch
+  config: TuiConfig.Resolved
+  capabilities: TuiCapabilities
+  paths: TuiPaths
+}
+
+export function run(input: TuiInput): TuiHandle
+export function createRenderer(config: TuiConfig.Resolved): Promise<CliRenderer>
+```
+
+- Preserve the existing lifecycle guarantees: readiness, waiting until exit,
+  idempotent cleanup, renderer destruction, SIGHUP handling where appropriate,
+  and terminal restoration.
+- Keep Windows process adapters outside the package if they mutate host process
+  state; invoke them from CLI adapters around the package lifecycle.
+- Keep OpenTUI parser-worker embedding in executable build scripts.
+- Move app lifecycle and rendering tests to `packages/tui`.
+
+Exit criteria:
+
+- `packages/tui` contains the canonical application root.
+- The package has no imports from `packages/opencode`, `packages/cli`, or
+  `@opencode-ai/core`.
+- The package public API is sufficient for both old and new CLI adapters.

+## Section 9: Convert Both CLIs To Thin Adapters
+
+Status: Completed. The legacy thread and attach commands now lazily invoke the
+public `@opencode-ai/tui` root while retaining worker/server/config/plugin and
+process adapters. The new CLI default command launches the same package against
+its authenticated daemon transport with a minimal local platform/host. Missing
+legacy provider/config APIs currently degrade to the shared provider-connect
+screen; source and compiled new-CLI behavior match, while named commands remain
+outside the TUI path.
+
+Make both executable packages consume the same TUI package.
+
+Tasks:
+
+- Keep the legacy yargs commands corresponding to current `thread.ts` and
+  `attach.ts` in `packages/opencode`.
+- Keep the legacy embedded worker and server startup in `packages/opencode`.
+- Change those adapters to load config, create transport inputs, and call the
+  public `@opencode-ai/tui` API.
+- Change `packages/cli`'s default command handler to call the same public API.
+- Remove the temporary `packages/cli/src/tui` shell after the shared package is
+  integrated.
+- Remove duplicated OpenTUI lifecycle code from both hosts.
+- Ensure non-TUI subcommands remain lazily isolated from OpenTUI startup.
+- Update executable build scripts to bundle the shared package, parser worker,
+  assets, and any retained host worker.
+
+Exit criteria:
+
+- Both CLIs launch the same package implementation.
+- There is no duplicate TUI source tree in `packages/cli`.
+- Legacy attach and local-worker modes still work.
+- Named non-TUI commands do not launch or eagerly initialize the TUI.

+## Section 10: Remove Compatibility Paths And Finish Ownership
+
+Status: Completed. Package source imports are self-contained, package exports
+are narrowed to active host contracts, package-owned tests and snapshots live
+under `packages/tui`, and the obsolete compatibility tree has been removed.
+Legacy command, worker, config, plugin-loader, process, editor, audio, and event
+adapters now live in explicit host-owned locations outside `src/cli/cmd/tui/`.
+
+Delete migration scaffolding only after both hosts consume the package.
+
+Tasks:
+
+- Remove old TUI compatibility re-exports and the obsolete directory tree under
+  `packages/opencode/src/cli/cmd/tui`.
+- Retain and relocate only true host adapters such as legacy commands, worker,
+  transport setup, and config loading.
+- Remove obsolete `@tui/*` path mappings from `packages/opencode`.
+- Remove stale test fixtures and update all imports to package exports.
+- Narrow `@opencode-ai/tui` exports to intentional public entrypoints.
+- Verify package manifests list every direct dependency and no accidental
+  dependency is supplied only by workspace hoisting.
+- Update repository documentation describing TUI ownership and development.
+
+Exit criteria:
+
+- No production import references the old TUI source location.
+- No source under `packages/tui` imports `@/...`, `@opencode-ai/core`, or either
+  executable package.
+- The old TUI directory contains no canonical implementation files.
+- The dependency graph has no cycle.
+
+Checkpoint commit:

+```text
+refactor(tui): complete standalone package extraction
+```
+
+## Invariants To Preserve
+
+- There is one canonical TUI implementation at every migration stage.
+- Legacy TUI behavior remains available until its host is intentionally removed.
+- The default new CLI command launches the TUI, while named subcommands continue
+  to route to their own handlers.
+- Renderer cleanup restores the terminal on normal exit, interruption, startup
+  failure, and renderer destruction.
+- TUI package imports do not reach into executable or backend implementation
+  packages.
+- SDK wire data is treated as the source of truth for OpenCode domain state.
+- Unknown tools and plugin data render safely without backend type imports.
+- Remote-server use remains possible; the TUI must not require an in-process
+  backend implementation.
+- TUI-local persistence remains local and does not become server state unless
+  there is an explicit product requirement.
+- Team changes should be moved with their canonical file, not manually copied
+  between old and new implementations.
+
+## Verification Gates
+
+Run verification after every section, adding narrower tests for the area being
+moved.
+
+Package checks:
+
+```text
+cd packages/tui && bun typecheck
+cd packages/tui && bun test
+cd packages/opencode && bun typecheck
+cd packages/cli && bun typecheck
+```
+
+Dependency checks:
+
+```text
+rg "from ['\"]@/" packages/tui/src
+rg '@opencode-ai/core|packages/opencode|packages/cli' packages/tui
+rg 'src/cli/cmd/tui|@tui/' packages/opencode/src packages/opencode/test
+```
+
+SDK checks when server APIs change:
+
+```text
+./packages/sdk/js/script/build.ts
+git diff --check
+```
+
+Interactive smoke checks should run in `tmux` so the terminal can be captured
+and cleaned up reliably:
+
+- Start the legacy local TUI and confirm initial render.
+- Start legacy attach mode against a server.
+- Start the new CLI default command and confirm it renders the same package.
+- Exit each mode with Ctrl-C and verify the process and terminal are restored.
+- Run representative named commands in both CLIs and verify they do not launch
+  the TUI.
+
+Compiled checks:
+
+- Build the current-platform `packages/opencode` binary.
+- Build the current-platform `packages/cli` binary.
+- Run TUI and non-TUI smoke checks against both compiled binaries.
+- Verify theme JSON, audio assets, OpenTUI parser worker, and retained backend
+  worker assets are included.

+- Trigger automatic compaction before provider turns using the complete estimated request and absolute model-aware headroom.
+- Preserve the existing structured summary contract and update prior summaries with newly compacted history.
+- Store token-bounded recent history as plain serialized text inside the checkpoint instead of replaying provider-native messages.
+- Keep compaction starts durable and progress deltas live-only; activate history cutover only from a durable completed summary.
+- Store the completed event with the current checkpoint payload containing stable message identity, reason, summary, and recent context.

+- Preserve full durable history; compaction changes only the active model representation.
+- Defer provider-overflow recovery, explicit manual compaction, and deterministic old tool-result pruning.

 Record V2 database, durable-event, projected-message, HTTP, and generated SDK schema changes here. Each entry states why the contract changed and whether consumers or stored data need compatibility handling. Commit messages for schema-affecting changes should include the same summary.
 
 This document covers meaningful contract changes introduced on the `feat/opencode-embedded-api` branch since its divergence from `origin/dev`. Mechanical file moves and internal refactors are omitted unless they changed stored data, replay behavior, public HTTP or SDK shapes, or model-facing tool contracts.

+
+Affected schema:
+
+- `session_input`, `session_message`, `event`, `event_sequence`, and disposable workspace beta storage.
+- New synchronized `session.next.prompt.admitted.1` and `session.next.prompt.promoted.1` events.
+- Experimental `SessionV2.prompt(...)`, HTTP, and generated SDK admission receipt.
+
+Change:
+
+- Replace inbox-local admission sequence with event-sourced prompt admission and promotion sequences.
+- Give projected Session messages stable `msg_*` resource IDs distinct from `evt_*` creator event IDs.
+- Give every event that creates a projected transcript resource an explicit `msg_*` resource ID. Assistant steps propagate one `assistantMessageID` through assistant-owned events.
+- Reset incompatible unreleased beta event history, derived Session projections, workspace rows, and Session workspace links.
+
+Compatibility:
+
+- The reset preserves canonical V1 `session`, `message`, and `part` rows.
+- Existing synchronized workspaces are disposable beta state and are removed by the reset.
+- Before starting the new build, discard adapter-managed external workspace resources created by unreleased builds. The SQL migration cannot remove external resources through runtime adapters, and rediscovering retained resources after startup can replay incompatible beta history.
+- Exact prompt retries reconcile one stable `msg_*` identity when Session, prompt, and delivery mode match.

+## Context Epochs
+
+V2 Sessions persist the exact privileged System Context shown to the model. A Context Epoch stores one immutable provider-cache baseline and a model-hidden structured snapshot used to compare independently observed Context Sources. Environment facts, the host-local date, ambient global/upward-project `AGENTS.md` files, and selected-agent available-skill guidance are the initial sources. Location-wide sources come from the System Context Registry; selected-agent guidance composes with them immediately before Context Epoch admission.
+
+The first complete observation initializes the epoch before any pending prompt becomes model-visible. If initial context is temporarily unavailable, execution stops while the prompt remains pending and retryable. On later provider turns, the runner promotes eligible input first, then reconciles current sources at the safe boundary. Changed context becomes one durable chronological System message, and its event commit advances the epoch snapshot atomically.

+Agent and model selection are provider-turn scoped. A switch admitted after the current safe provider-turn boundary applies to the next provider turn without restarting the current turn or replacing the baseline. Agent-specific skill guidance remains a Context Source, so changed guidance is admitted as a chronological System message. A completed compaction causes the next provider attempt to render a fresh baseline directly from current complete context. A Session move clears the epoch so the destination Location initializes a complete baseline on its next run.

+Ambient project discovery canonicalizes and contains traversal within the project root and honors `OPENCODE_DISABLE_PROJECT_CONFIG`. An unavailable observation preserves the previously admitted value.

+
+Current Context Epoch follow-ups:
+
+- Add configured, remote, and nested instruction sources with explicit precedence and removal semantics.
+- Add durable post-crash continuation recovery for promoted or provider-dispatched work.
+- Add explicit manual compaction on top of automatic request-budget compaction.
+- Add operational metrics for observation latency, unavailable sources, contention, baseline size, and chronological-update growth.
+- Consider watcher-backed per-file caching only if measurements show direct safe-boundary observation is too expensive.
+- Expose plugin-defined Context Sources only after plugin reload and scoped cleanup semantics are designed.
+- Add clustered Session execution ownership and stale-runtime fencing.
+
+## Automatic Compaction
+
+Before each provider turn, the runner estimates the complete model-visible request and compares it with the selected model's context window minus absolute reserved headroom. The reserve is the greater of the requested/model output allowance and configured `compaction.buffer`. When the request exceeds that budget and older complete turns are available, the runner compacts before executing the pending turn.
+
+Compaction keeps the full transcript durable while replacing its active model representation with one hidden checkpoint containing a structured rolling summary and token-bounded serialized recent context. Provider-native assistant, reasoning, and tool messages never survive across the boundary, avoiding signature and encrypted-reasoning failures when the earlier prefix changes.
+
+`session.next.compaction.started.1` durably identifies the attempt. Compaction deltas are live-only progress. `session.next.compaction.ended.1` durably stores the final summary and serialized recent context; only this completed event projects a model-visible compaction message. On the next provider attempt, the runner observes that completed compaction and directly renders a fresh Context Epoch baseline. A failed or interrupted attempt therefore leaves the previous history boundary active.
+
+Repeated compactions update the previous structured summary with newly compacted messages. The runner then reloads projected history and executes the original pending turn.
+
+When a provider rejects a request as context overflow before durable assistant output or tool execution, the runner attempts one overflow-triggered compaction even when the local estimate did not predict pressure. A completed checkpoint rebuilds the same logical provider turn with one remaining physical attempt. A second overflow, unavailable compaction, or overflow after durable output becomes the ordinary terminal failure; recovery never loops or replays partial side effects. Deterministic old tool-result pruning remains a separate follow-up.
+
+## V1 Runtime Context Parity
+
+This is the canonical checklist for model-visible runtime context still needed before the V2 runner replaces V1. Keep each behavior in its owning boundary rather than treating all model-visible text as a durable Context Source. Update this table in the PR that changes a status.
+
+Status: `complete` is usable in the native V2 path, `partial` covers only part of V1 behavior, and `missing` has no native V2 equivalent.

 Provider timeout, retry, and watchdog policy is intentionally deferred. The runner does not impose a universal provider-stream inactivity or absolute timeout. A future slice should design configurable policy around provider behavior, durable failure reporting, and local drain-chain release rather than hardcoding one default for every provider.
 
 Inbox delivery is explicit:
 
 - `steer` inputs promote at the next safe provider-turn boundary, including continuation inside the current drain.
-- `queue` inputs form a FIFO of future activities. When the current activity settles, the runner promotes exactly one queued input to open the next activity. Multiple queued inputs remain separate activities.
+- `queue` inputs remain in a FIFO while the current drain requires continuation. When the Session would otherwise become idle, the runner promotes exactly one queued input, then reevaluates continuation before promoting another.
 
 Execution has two entry points:
 
-- `run` is an explicit resume. It joins an active drain chain or starts one, and performs at least one provider attempt even when no input is eligible.
+- `run` is an explicit resume. It joins any active execution or starts a forced drain while idle. A forced drain bypasses the no-eligible-input guard, but preparation may still fail before a provider attempt.
 - `wake` reports newly recorded durable inbox work. Repeated wakes coalesce. A wake calls the provider only when it can promote eligible input.
 
-Post-crash activity recovery is intentionally deferred. A wake does not infer that ambiguous provider work is safe to retry after an input has already been promoted. Explicit `run` may deliberately continue from durable projected history. A future recovery slice should model durable activity identity, provider-dispatch ambiguity, required continuation, queue-opener reservation, retry policy, and visible recovery status together.

+A process-global `SessionRunCoordinator` serializes execution for each local Session while allowing different Sessions to run concurrently. Resumes join active execution, overlapping wakes coalesce into one follow-up, and interruption stops current process-local execution without deleting durable inbox work.

-Inbox promotion coalesces pending steers in durable admission order and opens one queued activity at a time in FIFO order. Add explicit inbox backlog and steering-batch limits before exposing broad multi-caller admission or untrusted queue growth.

 Eager local-tool execution is intentionally unbounded in the current local slice. This minimizes tool latency but does not increase SQLite settlement throughput: Session-event publication remains serialized per provider turn. Before broadening exposure, revisit per-turn call limits, output truncation, and operational backpressure using observed workloads. The `session.next.*` event schemas remain experimental and unshipped; databases created by earlier experimental builds are disposable rather than compatibility targets.

+# V2 Tools
+
+## Design
+
+V2 has one opaque type for locally executable tools:
+
+```ts
+type Definition<Input, Output>
+type AnyTool = Definition<any, any>
+
+const make: <
+  Input extends Schema.Codec<any, any, never, never>,
+  Output extends Schema.Codec<any, any, never, never>,
+>(config: {
+  readonly description: string
+  readonly input: Input
+  readonly output: Output
+  readonly execute: (
+    input: Schema.Type<Input>,
+    context: Tool.Context,
+  ) => Effect.Effect<Schema.Type<Output>, ToolFailure>
+  readonly toModelOutput?: (input: {
+    readonly input: Schema.Type<Input>
+    readonly output: Output["Encoded"]
+  }) => ReadonlyArray<Tool.Content>
+}) => Definition<Input, Output>
+```
+
+Application tools, built-ins, and statically authored plugin tools use this same constructor and execution contract.
+
+`Tool.Definition` is opaque and has exactly one executor. Its schemas and executor are not public fields. The Tool module privately derives model definitions and interprets invocations for the registry; callers normally rely on `Tool.make` inference rather than naming the carrier type.
+
+Input and output codecs are self-contained. Schema conversion cannot require services. Tool dependencies are acquired during construction and captured by `execute`.
+
+## Invocation Context
+
+Every local tool receives the same concrete invocation context:
+
+```ts
+interface Tool.Context {
+  readonly sessionID: Session.ID
+  readonly agent: Agent.ID
+  readonly assistantMessageID: Session.MessageID
+  readonly toolCallID: ToolCall.ID
+}
+```
+
+`assistantMessageID` is the durable ID of the assistant message containing the call. The Session runner owns this association and supplies the complete context to the registry; the registry does not infer it.
+
+Decoded tool input is passed separately to `execute`. Raw provider input and domain services do not belong in the invocation context.
+
+Effect interruption is the cancellation mechanism. Tools may translate expected typed failures into `ToolFailure`, but must not translate interruption or defects into model-visible failures.
+
+## Registration
+
+Tools are named when registered:
+
+```ts
+yield *
+  tools.register({
+    read,
+    write,
+    grep,
+  })
+```
+
+The record key is the effective model-facing name. A reusable tool value has no intrinsic name.
+
+```ts
+interface Tools {
+  readonly register: (
+    tools: Readonly<Record<string, Tool.AnyTool>>,
+  ) => Effect.Effect<void, Tool.RegistrationError, Scope.Scope>
+}
+```
+
+Tool names use a conservative provider-neutral grammar and are validated at registration. Provider-specific restrictions that cannot be validated generically fail during request preparation with an explicit model-compatibility error.
+
+Process application tools and Location tools expose the same `register` operation but retain separate services and stores. Registration placement determines scope, precedence, and authority; it does not change the tool type.
+
+A Location plugin receives only the narrow `Tools` registration capability, not the internal registry. Its installation effect runs once per applicable Location, acquires that Location's services, constructs its tools, and registers them in the plugin-owned Scope.
+
+Within one placement:
+
+- The latest active registration for a name wins.
+- Closing a registration removes only that registration.
+- Closing the winner reveals the next-latest active registration.
+- Mutating the caller's registration record later does not change the captured registration.
+
+Location registrations take precedence over process application registrations.
+
+## Built-In Tools
+
+Built-ins use the same tool API while capturing trusted Location services:
+
+```ts
+const filesystem = yield * FileSystem.Service
+const permission = yield * PermissionV2.Service
+const tools = yield * Tools.Service
+
+yield *
+  tools.register({
+    grep: Tool.make({
+      description: "Search file contents",
+      input: Input,
+      output: Output,
+      execute: (input, context) =>
+        Effect.gen(function* () {
+          const root = yield* filesystem.resolveRoot(input)
+
+          yield* permission.assert({
+            sessionID: context.sessionID,
+            agent: context.agent,
+            source: {
+              type: "tool",
+              messageID: context.assistantMessageID,
+              callID: context.toolCallID,
+            },
+            action: "grep",
+            resources: [input.pattern],
+            save: ["*"],
+            metadata: { root: root.resource },
+          })
+
+          return yield* filesystem.grep(input, root)
+        }).pipe(/* translate expected typed errors to ToolFailure */),
+    }),
+  })
+```
+
+Trusted tools formulate and sequence permission requests. `PermissionV2` evaluates policy and manages approval. The registry does not inject an `assertPermission` helper.
+
+Sharing a tool type does not imply equal authority. Built-ins and trusted Location plugins may capture services that are not available to application tools.
+
+## Execution
+
+The Location-scoped registry owns effective lookup and settlement. For each local call it:
+
+1. Resolves one effective named registration.
+2. Decodes provider input with the input codec.
+3. Invokes the tool with the runner-supplied context.
+4. Encodes the returned output with the output codec.
+5. Projects encoded output into model-facing content.
+6. Bounds the complete model-facing output.
+7. Returns the settlement and managed-output references to the runner, which persists them durably.
+
+Invalid input never invokes the tool. Invalid output never produces a successful settlement.
+
+`toModelOutput` is pure and total. When omitted, the encoded output remains structured output; an encoded string is also projected as text. Projection does not receive invocation identity because presentation depends only on validated input and output.
+
+Provider-turn materialization captures the effective registration identity for each advertised name without retaining its handler. Settlement rejects the call as stale if that registration was removed or replaced, including when closing an overlay reveals the previously effective registration. The current handler is captured only after this check; removing or replacing its registration afterward does not affect the running invocation.
+
+## Output Bounding
+
+Tools return complete validated domain output. They do not truncate model-facing output or manage retention files.
+
+After projection, one generic settlement boundary bounds the channel actually sent to the provider. When content exists, only its textual parts are measured; structured metadata is retained unchanged without being double-counted, and native media remains unchanged under producer-owned limits. When content is empty, the structured output is measured. Oversized provider-facing text or structured output is retained in managed storage and replaced with a bounded text preview while structured metadata and media are preserved; if complete retention fails, settlement fails operationally rather than publishing lossy success. Managed paths never appear in `Tool.make`, tool output schemas, or projection callbacks solely for retention bookkeeping.
+
+Model-output bounding is not producer memory management. Processes and streaming sources may need separate capture or spooling limits before a tool result exists. Those limits must be modeled at the producer boundary and must not masquerade as model-output truncation. A producer cannot claim a complete retained output after it has already discarded bytes.
+
+## Failure Semantics
+
+Outcomes remain distinct:
+
+- `ToolFailure` is an expected model-visible failure.
+- Interruption cancels the invocation and is not a tool result.
+- Unexpected typed errors and defects follow the runner's operational failure policy.
+- Unknown, invalid, and stale calls become explicit model-visible settlement errors without invoking a handler.
+
+Leaf tools translate only errors they deliberately classify as recoverable. Broad cause-catching around an executor is invalid because it consumes interruption and defects.
+
+## Laws
+
+- **Single executor:** `Tool.make(config)` can invoke only `config.execute`.
+- **Codec boundary:** execution observes decoded input; projection observes encoded output.
+- **Durable identity:** invocation-owned records use the exact Session, agent, assistant message, and call IDs supplied by the runner.
+- **Scoped registration:** closing a Scope removes exactly its registration and reveals any prior active overlay.
+- **Captured execution:** registration changes cannot alter an invocation after effective lookup.
+- **Stale rejection:** a call never executes a registration other than the one advertised for its provider turn.
+- **Storage encapsulation:** domain output does not change according to model-output bounding or retention policy.
+
+## Follow-Up
+
+Location plugin installation should receive the same narrow `Tools` capability. That requires a separate Location-layer ordering change so built-ins register before plugins without introducing a `PluginBoot -> Tools -> PluginBoot` dependency cycle. The carrier, registrar, and plugin-owned Scope semantics are already suitable; no tool-specific plugin hook is needed.
+
+Session's current public result shape still exposes managed `outputPaths`. Extending storage encapsulation across the public Session API requires a separate opaque managed-output reference design; paths are not entirely internal today.
