The Cline CLI (npm `cline`, 3.x) stores sessions as
<sessions>/<id>/<id>.json + <id>.messages.json. The existing `cline`
provider only discovers tasks/<id>/ui_messages.json, so every CLI session
was silently reported as $0.00 — no warning, not even under --verbose.
Adds `cline-cli` as its own provider rather than a third root on `cline`,
leaving the shared Cline-family parser (Roo Code, KiloCode, IBM Bob)
untouched. It mirrors the CLI's own root resolution
(CLINE_SESSION_DATA_DIR -> CLINE_DATA_DIR -> CLINE_DIR -> ~/.cline),
implements probeRoots() so `doctor` can tell "not installed" from "wrong
override", emits one call per assistant message's `metrics` block, and
falls back to the session rollup when a session carries none. The
fallback reads `usage`, not `aggregateUsage`, which folds in spawned
subagents that are themselves separate session directories.
Two supporting changes, both required for CLI costs to report correctly:
- parser.ts re-priced cline-cli calls from tokens because the provider
was not on the reported-cost allowlist, inflating a real 12-session
local sample from $1.11 to $3.92.
- session-cache.ts gains the matching PROVIDER_ENV_VARS entry (so a
changed override invalidates) and a `reported-cost-v1` parse version
(so sessions cached before the allowlist fix re-parse once instead of
being re-priced forever).
Cost is treated as metered only when actually present and non-negative,
so a metered $0 stays reported while a missing or negative cost falls
back to token pricing — applied identically on the per-message and
rollup paths. Timestamps promote a seconds-resolution value rather than
silently landing in 1970, matching the guard kiro.ts uses.
CLINE_DIR / CLINE_DATA_DIR / CLINE_SESSION_DATA_DIR are added to the test
env-isolation list so a developer's real sessions cannot bleed into
fixtures.
The VS Code variant discovery bug reported alongside this in #874 is
deliberately NOT fixed here — it shipped in #882.
Verified against 18 real local sessions: 142 calls, 4,934,762 input /
224,561 output tokens, and a cost matching the CLI's own metered total to
the cent. `codeburn doctor` reports "Cline CLI OK".
Refs: #874
Cline discovery only looked at the stable VS Code globalStorage root, so
tasks created in VS Code Insiders or VSCodium were never found. The
singular getVSCodeGlobalStoragePath helper returns paths[0], and because
the provider always passed a concrete overrideDir, the 3-variant fallback
inside discoverClineTasks was never reached - unlike the Roo Code and
KiloCode siblings, which pass overrideDir straight through.
Build the default roots from getVSCodeGlobalStoragePaths (stable,
Insiders, VSCodium) plus the ~/.cline/data root and hand them to
discoverClineTasks in one call. The existing dedupe by task id still
collapses a task id seen in more than one root, so totals cannot inflate.
The configuredDirs override used by tests and createClineProvider(dirs)
is unchanged.
