* test(#4794): failing-first — could-not-parse must answer an unmeasured shape; a directory context path fails closed * fix(#4794): could-not-parse answers an unmeasured shape (null counts, unreadable ids, no uncovered); a non-file context path fails closed * chore(#4794): backfill changeset PR number (4889) * test(#4794): skip the directory-identity probe when the platform cannot discriminate (windows runner volume collapse, measured) Two consecutive windows conformance runs failed the probe with measured identical (dev, ino) for two distinct mkdtemp directories (dev=3606225537, ino=9007199255243448 for both) — a runner-volume property, not a regression in the guard. On such a platform the guard's identity containment degrades to refuse-everything (fail-closed, documented); the probe asserts capability, so the honest response is an explicit t.skip carrying the measurement (ADR-2719 §6), not a red lane for every PR. --------- Co-authored-by: sim <sim@local>

|
|
* Bug #3407: Installer leaves stale content in gsd-pristine/
|
|
*
|
|
* Root cause: populatePristineDir() in saveLocalPatches() snapshots from
|
|
* pristineCtx.packageSrc — the NEWLY-downloaded release tree — and writes
|
|
* those bytes into gsd-pristine/. For files changed between the old and new
|
|
* release, this writes the NEW bytes into the pristine baseline instead of
|
|
* the OLD bytes. The three-way-diff verifier then classifies upstream-changed
|
|
* lines as user-added → Step 5a gate fails with false FAIL_USER_LINES_MISSING.
|
|
*
|
|
* The #3657 fix (OK_PRISTINE_DRIFT_DETECTED) was a symptom workaround: the
|
|
* verifier detects hash mismatch (backup-meta.json records old-release hash
|
|
* but gsd-pristine/ has new-release bytes) and skips to over-broad mode
|
|
* instead of false-failing. The root-cause stale write was never fixed.
|
|
*
|
|
* Fix: when a correctly-populated gsd-pristine/ already exists from the
|
|
* previous install (i.e., the file's sha256 matches the originalHash recorded
|
|
* in the manifest), preserve it — do NOT wipe and re-populate from the new
|
|
* release source. This ensures gsd-pristine/ holds old-release bytes even
|
|
* after an upgrade where the file content changed upstream.
|
|
*
|
|
* Regression contract (byte-comparison):
|
|
* After saveLocalPatches() is called with a user-modified file whose
|
|
* gsd-pristine/ entry was correctly set by the previous install, the
|
|
* gsd-pristine/ file MUST still contain the old-release bytes, not the
|
|
* new-release bytes supplied in pristineCtx.packageSrc.
|
|
*
|
|
* Closes: #3407

/**
|
|
* #3712 — an in-process run must never reach the developer's REAL home.
|
|
*
|
|
* The confinement rows above bound a write to the root they are handed. A kind
|
|
* may ALSO declare a global `home` override resolved from `os.homedir()` rather
|
|
* than from configDir (today: codex's skills kind, `home: ".agents"`, ADR-1239 /
|
|
* #2088). assertDestWithinConfigHome cannot see that class: it confines a
|
|
* destSubpath to whatever root it is given, and here the root IS the escaped home.
|
|
*
|
|
* The live defect: an in-process caller that forgot to sandbox HOME pruned the
|
|
* real ~/.agents/skills — 71 gsd-* dirs deleted, a foreign `cloudflare` skill
|
|
* surviving, suite still exit 0, because the runtime's own config home was
|
|
* untouched and the manifest kept reporting a healthy install.
|
|
*
|
|
* SIX writers resolve a kind `home` and then write or destroy under it. The four
|
|
* reachable today are covered below by driving the REAL entrypoint — not the
|
|
* predicate — so that deleting a guard call site turns these rows red. The other
|
|
* two, `installOpencodeFamilySkills` and `installAgentsKindStandalone`, are
|
|
* guarded but not wiring-tested: no runtime declares a `home` override on those
|
|
* kinds, so neither path can be exercised without inventing a descriptor.
|
|
*
|
|
* The sixth, `migrateLegacyDevPreferencesToSkill`, CREATES rather than prunes and
|
|
* runs from `_runLegacyInstallMigrations` — i.e. BEFORE installRuntimeArtifacts'
|
|
* own assertion — so it carries its own guard call and its own wiring row. The
|
|
* count read FIVE/three until review of #3725 caught the row missing.
