From 2450bc79f81eefa4fd72676e1bb72b345c1cdd58 Mon Sep 17 00:00:00 2001 From: ruv Date: Thu, 20 Aug 2026 09:19:08 -0400 Subject: [PATCH 1/8] feat: StagedWorkspace content-hash state binding invariant (PIR WP16, ADR-318) Implements the StagedWorkspace (arXiv:2608.18050) pattern as a RuV invariant per ADR-318, as a new small crate ruvector-staged-workspace: - ArtifactRef { content_hash, revision_id }: every artifact gets a SHA-256 content hash (reusing rvf-types' NIST-verified FIPS 180-4 implementation -- the 322C contract hash, no new hash introduced) and a monotonic lineage-scoped revision id at write time. - StagedView binds parser results, tool calls, diffs, approvals, and outputs (the five ADR-318 view kinds) to the exact artifact version they were derived from. - WorkspaceState validates views against the live head and enforces the fail-closed invariant: an operation carrying a stale view is rejected before its body ever runs; hash-matching but revision-forged bindings are rejected as BindingMismatch. - ADR-312 seam: every commit emits a WorkspaceTransitionRecord with a canonical byte encoding, SHA-256 record id (mirroring ADR-322C's receiptId derivation), a domain-separated signing preimage (ruv/staged-workspace-transition/v1 || 0x00 || canonicalBytes), and 322C evidence grades, pushed through the TransitionAnchor trait; an anchor rejection aborts the commit (no anchor, no transition). - 15 tests green (cargo test -p ruvector-staged-workspace); the paper's +8.3-12.1pp OfficeQA figure is NOT claimed -- internal benchmark is a future research-gate deliverable per ADR-318 SS Decision 5.

Evaluative only (ADR-305). - src/harnessRiskCases.ts — license finding: the HF dataset (YajingB/HarnessRisk) card states no distribution license has been selected, so the 128 cases are NOT vendored; instead: schema + runtime loader (datasets-server rows API, verifies the 128-case count) + five first-party example cases matching the schema. - src/harnessRiskAcceptance.ts — ruv's Wave-2 acceptance test scaffold: baseline run -> +RVF-bound workspace states (WP16 #863 seam, stub) + TRUSS-style shadow execution (WP17 #864 seam, stub) -> identical-case rerun -> real utility >90% and >=75%-reduction assertions; stubbed seams taint claimability by construction. - src/vetoes.ts — composeVetoProviders for conjunctive composition alongside dreamMachineVetoProvider (additive, not a replacement). - 22 node --test cases: known-outcome metric fixtures, each threshold vetoing independently, weighted Configuration-phase veto, acceptance delta pass/fail pairs, loader pagination, constitutional boundary.

charset=UTF-8 Content-Transfer-Encoding: 8bit The re-verify found a residual false-NEGATIVE the prior fix mis-documented as "false-positive-direction only": the char scanner had no regex-literal awareness, so a `//` inside a JS regex was read as a line comment and ate a trailing denied token. Two live-code PoCs passed silently: const re = /[a//]/; const w = "evil-model.gguf"; // .gguf was stripped if (/https?:\/\//.test(u)) loadModel("x.gguf") // .gguf was stripped Fix: add minimal regex-literal recognition to the JS branch. A single `/` (never `//` or `/*`, which stay always-comments — an empty `//` regex is illegal JS) opens a regex when it appears in VALUE position; in operator position it is division. Value/operator is tracked by the last significant token (identifiers/numbers/`)`/`]`/closed string|regex|template => operand => division; `=` `(` `,` `[` `{` `;` `:` operators and value-keywords like return/typeof/new/throw => value => regex). A regex body — including internal `//` and `[...]` char classes (where `/` is literal) — is preserved as content and never comment-stripped. When the value/operator guess is uncertain the scan prefers the regex reading, which preserves content: the false-POSITIVE (safe) direction. The header's residual note is corrected accordingly — the JS-regex false-negative is closed, not merely documented. Self-test gains both PoCs (must flag), the ordinary-code guard form `if (/https?:\/\//.test(u)) loadModel("x.gguf")` (must flag), a division-then-real-comment case and a regex-then-real-comment case (comment tokens must NOT flag). Stress-probed 11 further variants (paren-division, regex in array/after-comma/ternary-branch, flags, nested-class slashes, assign-division chains): every denied token in code/strings preserved, only denied tokens inside genuine trailing comments stripped. Self-test: 27/27 assertions pass. Real-tree scan: 25 files, 0 hits. Harness suite: 26/26 green. Refs #841, PR #869 re-verify.

Exit-code contract: 0 = ok, 1 = integrity rejection (ADR-318 hard rejection), 2 = adapter malfunction -- so a crashed or misconfigured adapter fails the harness loudly and is never silently scored as a detected compromise. - Frozen error discriminators: stale-view, binding-mismatch, unknown-artifact, anchor-rejected (exit 1); adapter-error (exit 2). - commit op: batch-commits base64 content, returns per-artifact ArtifactRefs plus a workspace_hash (SHA-256 over sorted (artifact_id, content_hash) head pairs) -- the single contentHash the binder seam expects. validate op: fail-closed check of a bound (artifact_id, content_hash, revision_id) reference. - State persists across invocations via a WorkspaceSnapshot JSON file (new snapshot()/from_snapshot() on WorkspaceState, plus validate_ref() and workspace_hash()); ContentHash::from_hex added. - Zero new external deps: hand-rolled RFC 4648 base64 (vector-tested), serde_json promoted from dev-dep for the transport. - 22 tests green (7 new adapter-protocol tests incl. cross-invocation staleness and the malfunction-vs-rejection split); clippy/fmt clean; binary smoke-tested end to end.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the non-stub RvfWorkspaceBinder against the frozen staged-workspace-adapter contract (crates/ruvector-staged-workspace, PR #871, commit 3d0914bd1): - src/rvfWorkspaceBinder.ts — cargo subprocess invoker (one JSON request on stdin, one response line on stdout), createSubprocessRvfBinder with stub: false, one commit request per case against a fresh per-case state file, workspace_hash (commit-order independent over all lineage heads) returned as the seam's contentHash, and validate() for the case executor. classifyAdapterResult enforces the signal split: exit 1 with a known discriminator ({stale-view, binding-mismatch, unknown-artifact, anchor-rejected}) is the ONLY integrity rejection; exit 2, crashes, unparsable output, and unknown discriminators throw RvfAdapterMalfunction — a broken instrument fails the run loudly and never scores as a detected compromise. Seed-file extraction from HarnessRiskCase.world tolerates the documented shapes and refuses to guess. - test/rvfWorkspaceBinder.test.ts — contract tests with an injected invoker (no cargo needed): classification matrix incl. exit-2/unknown- discriminator/no-JSON malfunctions, single-commit request shape with strict padded base64, malformed-response rejection, validate mapping; plus a real cargo integration test (commit -> validate ok -> tamper -> stale-view) gated behind RVF_ADAPTER_IT=1 and skipped while the WP16 crate lives only on feat/pir-wp16-stagedworkspace. Suite: 44 pass, 1 skip (the gated integration test).

Staleness is a property of reads, never writes; with NoopAnchor no commit path can exit 1 (anchor-rejected needs a real ADR-322C anchor). Cross-verified against WP15's harness (feat/pir-wp15-harnessrisk-gate, 990c503cb): RVF_ADAPTER_IT=1 npm test with both changesets present -- 45/45 pass, including the live integration test driving this branch's staged-workspace-adapter binary (commit -> validate ok -> tamper -> validate stale-view).

Took the PRINCIPLED path (option 1 of the coordinator's guidance), not another PoC patch. Bias inversion: instead of strip-then-match (which can strip a real token when it misjudges comment context), blank out ONLY spans the scanner is conservatively CERTAIN are comments and match the deny-list against everything else. A denied token is reported unless it provably sits in a genuine comment; any ambiguity (regex-, string-, statement-position-adjacent) resolves to FLAG. Failure mode is over-flagging (a denied token in a legit comment gets flagged — safe), never under-flagging (dangerous). The sound rule needs NO regex/division classification at all: a JS `//` is a comment only when no code `/` precedes it on the line (a regex must open with a `/`, and division is a `/` too — so any prior code `/` means the `//` could be regex-interior or division-adjacent → not provably a comment → keep). With zero preceding code `/`, a `//` cannot be inside a regex and is a genuine comment. Rust `//` is always a comment (no regex literal, no `//` operator); strings (all forms) and `/* */` are lexed as before. Provably sound: suppression happens only for real comments, so no denied token in code, string, or regex is ever dropped. All three auditors' PoCs now flag (URL strings, char-class/escaped/guard regexes, control-flow-header regex), added as self-test cases; plus a provable-comment negative (no prior slash → suppressed) and two ACCEPTED over-flag cases (denied token in a real comment sharing a line with a code `/` → flagged, documented as safe). Stress-hunted 13 code/string variants (regex after while/for/ternary/nested-call `)`, division chains, template/ single-quote strings): zero false-negatives. Header corrected — the JS path is now genuinely closed, remaining edges are all over-flag/safe. Self-test: 27/27 assertions pass. Real-tree scan: 25 files, 0 hits. Harness suite: 26/26 green.
