 #### For contributors
 - `lib/merge.ts` holds the pure regime logic (detection precedence, submit planning, landing classification, handoff schema + validation); `test/gstack-merge.test.ts` (30) and `test/gstack-merge-cli.test.ts` (11) pin it. A generated-doc scrub test fails CI if `/land`'s SKILL.md ever grows deploy/canary machinery. The merge SHA → revert handoff and the never-blind-retry invariant (cli/cli#3442, cli/cli#13380) moved into `/land` with their tests.
 
+## [1.57.7.0] - 2026-06-08
+
+## **Every plan review now ends by telling you, in one line, whether anything is still unresolved.**
+## **The GSTACK REVIEW REPORT closes with the open decisions, or "NO UNRESOLVED DECISIONS" in plain sight, before you approve.**
+
+When a plan-review skill (/plan-ceo-review, /plan-eng-review, /plan-design-review,
+/plan-devex-review, and /codex) finishes and hands you the plan to approve, its report
+now ends with a mandatory unresolved-decisions verdict. If decisions are still open, it
+lists each one and what breaks if you ship it deferred. If nothing is open, it prints the
+exact line NO UNRESOLVED DECISIONS. A token-reduction pass had made this line optional, so
+a clean plan and a plan hiding an open question rendered the same. Now the line is never
+omitted, it is always the last thing you read before the approval prompt, and the approval
+gate refuses to let the plan through without it.
+
+### What changed, before and after
+
+| At plan-approval time | Before | After |
+|---|---|---|
+| Clean plan | usually no unresolved line | `NO UNRESOLVED DECISIONS` as the final line |
+| Plan with open decisions | unresolved line optional, often dropped | `**UNRESOLVED DECISIONS:**` + one bullet per open item |
+| Approval gate (ExitPlanMode) | checked the line "if applicable" | blocks unless the unresolved status is the final line |
+| /plan-devex-review review log | never written, gate uncheckable | written, so the dashboard and report see its data |
+
+The unresolved count across reviews is computed without double-counting the review that
+just ran, using the same 7-day freshness window as the Review Readiness Dashboard.
+
+### What this means for you
+
+Every approve-plan moment now carries an explicit verdict on open questions, so a missed
+ambiguity cannot slip through looking like a clean plan. If you run the plan-review skills
+or /autoplan, you will see the unresolved status as the closing line of every report.
+Nothing to configure. Upgrade and your next plan review shows it.
+
+### Itemized changes
+
+#### Added
+- **Mandatory unresolved-decisions status in the GSTACK REVIEW REPORT.** Generated into
+  all six report consumers (/plan-ceo-review, /plan-eng-review, /plan-design-review,
+  /plan-devex-review, /codex, /devex-review) from `scripts/resolvers/review.ts`. The report
+  always ends with either the exact unbolded sentinel `NO UNRESOLVED DECISIONS` or a
+  `**UNRESOLVED DECISIONS:**` bullet block listing each open item; never omitted, always
+  the final line.
+- **Blocking approval gate.** The EXIT PLAN MODE GATE now refuses ExitPlanMode unless the
+  report's final non-whitespace line is the unresolved status (no "if applicable" escape).
+- Static and E2E tests pinning the mandatory status across every report consumer and
+  gate-bearing skill, so a future compression pass cannot silently drop it again.
+
+#### Fixed
+- **/plan-devex-review never logged a review entry.** It carried the approval gate but
+  never called `gstack-review-log`, so the gate's "review log was called" check was
+  structurally unsatisfiable and its data was invisible to the Review Readiness Dashboard
+  and the report. It now logs with the correct timestamp and DX fields.
+
+#### For contributors
+- Rebased the parity-suite size baseline v1.53.0.0 to v1.57.7.0 (captures current union
+  sizes; keeps the per-skill 1.05 ratio so future bloat is still caught). Regenerated the
+  three ship golden fixtures left stale by #1909. The frozen v1.44.1 integrity anchor and
+  the v1.47 size-budget baseline are untouched.
+
+## [1.57.6.0] - 2026-06-07
+
+## **Eight community-filed bugs fixed in one wave, four of them security guards that were quietly failing open.**
+## **Your redaction gate now catches modern OpenAI keys, and `/ship`'s adversarial review stops choking on your own security tests.**
+
+This is a fix wave. The throughline: guards that reported success while doing nothing.
+The secret-redaction gate that every `/spec`, `/ship`, `/cso`, and `/document-*` run
+passes through was blind to modern `sk-proj-`/`sk-svcacct-`/`sk-admin-` OpenAI keys and
+silently dropped its size cap on a bad flag. The cross-project learnings trust gate was
+an allowlist on paper and a denylist in code, so untrusted rows leaked between projects.
+The destructive-action classifier waved through "rotate the database password." Each one
+looked like it was protecting you. None of them were. All four now fail closed, with
+tests that pin the exact case that used to slip by. Three more fixes clear silent
+crashes and skipped reviewers, and `/ship`'s adversarial pass no longer trips Anthropic's
+usage policy when it reads your repo's own attack-payload fixtures.
+
+### The numbers that matter
+
+Reproduce with `bun test test/redact-engine.test.ts test/gstack-learnings-search.test.ts test/one-way-doors.test.ts test/diff-scope.test.ts test/brain-cache-roundtrip.test.ts`.
+
+| Guard / path | Before | After |
+|---|---|---|
+| `sk-proj-`/`sk-svcacct-`/`sk-admin-` OpenAI keys | zero findings (HIGH fails open) | blocked, with prose false-positive guards |
+| `gstack-redact --max-bytes <garbage>` | NaN silently disables the size cap | rejected at the CLI; engine backstop holds |
+| Cross-project learnings with no `trusted` field | imported (denylist bug) | excluded (true allowlist) |
+| "rotate the database password" | classified two-way (auto-approvable) | classified one-way (always asks) |
+| `.mjs/.cjs/.mts/.cts`-only PRs | backend reviewer skipped | backend reviewer runs |
+| `_meta.json` missing `last_refresh` | brain-cache crashes (TypeError) | degrades to a cold cache |
+| Safety-skill hooks on Claude Code 2.1.162 | every Edit/Write errored | hooks resolve and run |
+| `/ship` adversarial review over security fixtures | denied by usage policy | runs, fixtures read in summary mode |
+
+The redaction one is the sharpest: a project/service-account/admin OpenAI key pasted
+into a spec or PR body used to sail straight through the gate. Now it blocks, and the
+calibration is pinned so hyphenated prose like "the sk-learning-rate schedule" does not
+false-positive and wedge your ship.
+
+### What this means for you
+
+If you rely on the redaction guard or the cross-project learnings gate, they now do what
+the docs always said. If you run `/ship` on a repo that tests its own security guards,
+adversarial review stops dying on contact with your fixtures. And if you are on Claude
+Code 2.1.162, `/guard`, `/freeze`, and `/careful` work again instead of erroring on every
+edit. Upgrade and re-run anything that touched these paths.
+
+### Itemized changes
+
+#### Fixed
+- **Redaction misses modern OpenAI keys (#1868).** `openai.key` (HIGH/block) used a
+  contiguous-alphanumeric pattern that stopped at the first `-`/`_`, so base64url-bodied
+  `sk-proj-`/`sk-svcacct-`/`sk-admin-` keys produced no finding and failed open through
+  every redaction sink. Replaced with explicit bare-vs-prefixed alternation; added
+  positive and false-positive tests. Reported by @jbetala7.
+- **Redaction size cap fails open on a bad flag (#1824).** A malformed `--max-bytes`
+  parsed to `NaN`, and `byteLen > NaN` is always false, silently disabling the
+  fail-closed oversize guard; a negative value blocked everything. The CLI now rejects
+  non-integer / non-positive values, and the engine falls back to the default cap as a
+  backstop. Reported by @jbetala7.
+- **Cross-project learnings trust gate leaked (#1745).** `gstack-learnings-search
+  --cross-project` is documented as an allowlist but was coded as `trusted === false`,
+  admitting any row missing the `trusted` field. Flipped to `trusted !== true`. Reported
+  by @jbetala7.
+- **Destructive-action classifier missed "rotate ... password" (#1839).** The `rotate`
+  keyword pattern omitted `password` while its `revoke`/`reset` siblings included it, so
+  the most common credential-rotation phrasing classified as a reversible two-way
+  question. Added `password` to the alternation.
+- **Review Army skipped backend reviewer on ESM/CJS PRs (#1810).** `gstack-diff-scope`
+  matched only `*.ts|*.js`; a PR touching only `.mjs/.cjs/.mts/.cts` reported no backend
+  scope. Added the four module extensions. Reported by @jbetala7.
+- **Brain-cache crash on a partial `_meta.json` (#1879).** `loadMeta` returned parsed
+  JSON verbatim; a file missing `last_refresh` crashed three consumers with a TypeError.
+  Added an object-shape guard and map normalization; missing schema/endpoint identity now
+  forces a safe rebuild rather than trusting a stale file. Reported by @jbetala7.
+- **Safety-skill hooks broken on Claude Code 2.1.162 (#1871).** `guard`, `freeze`, and
+  `careful` frontmatter hooks used `${CLAUDE_SKILL_DIR}`, which CC 2.1.162 no longer
+  populates, so every Edit/Write/Bash errored. Anchored the hook commands to the
+  installed checkout path. Reported by @omariani-howdy.
+- **`/ship` adversarial review denied on own security fixtures (#1899).** The Claude
+  adversarial subagent reasoned "like an attacker" over the full diff; when the diff
+  included the repo's own attack-payload regression fixtures, Anthropic's real-time
+  usage-policy safeguards denied the call. The subagent now carries authorized-defensive
+  -testing framing and reads fixture/test files in summary mode (no raw payload bytes),
+  stating so explicitly. Reported by @bmajewski.
+
+#### For contributors
+- `#1882` (skills hardcode `~/.claude/skills/gstack/`, breaking non-`gstack` install
+  dirs) is filed as the top item in `TODOS.md`. It was scoped out of this wave once it
+  proved to be a host-config/preamble change touching all 52 skills, distinct from the
+  `#1871` hook fix it was originally paired with.
+
+## [1.57.5.0] - 2026-06-07
+
+## **Your agent now keeps its decisions, not just its code.**
+## **The durable calls you make, and the "why" behind them, are captured, curated, and resurfaced across sessions, with no daemon to run.**
+
+Every session you and the agent settle real decisions: pick an architecture, cut a scope, choose a tool, reverse an earlier call. Until now that reasoning lived only in a transcript that scrolls away, so the next session re-litigates settled questions or loses the "why." This release adds an institutional decision memory. Durable decisions land in an append-only, event-sourced store, the scope-relevant ones surface automatically at session start, and you can search them any time. It is file-only and works with gbrain off; when gbrain is up you can add semantic recall on top. The planning and ship skills capture their own key calls so the high-value decisions get recorded without anyone remembering to. Separately, `/sync-gbrain` learned to build the cross-reference call graph and to heal a crashed daemon's stale lock instead of wedging every sync.
+
+### The numbers that matter
+
+No speed benchmark here, the win is capability and reliability. These are the real shape of the release (`git diff 1.57.0.0..HEAD`, `bun test`):
+
+| Metric | Value |
+|--------|-------|
+| New commands | 2 (`gstack-decision-log`, `gstack-decision-search`) |
+| Session-start read cost | O(active) bounded snapshot, not a full-history scan |
+| Works with gbrain OFF | Yes, every capture/curate/resurface path is files + bins only |
+| New source | ~2,550 lines across 26 files |
+| New tests | 117 across the decision store + gbrain stages |
+
+Resurfaced decision text is treated as data, not instructions (datamarked at the render boundary), secrets are blocked on write, and `redact` expunges a decision from every read path. The whole loop degrades cleanly: turn gbrain off and you still capture, curate, and resurface.
+
+### What this means for you
+
+Start a session tomorrow and the agent already knows what you settled and why, instead of asking again or quietly reversing it. Log a call with `gstack-decision-log`, reverse one with `--supersede`, pull the relevant history with `gstack-decision-search`. CEO, eng, spec, and ship reviews record their decisions for you. Run `/sync-gbrain` and a crashed autopilot no longer blocks your next sync.
+
+### Itemized changes
+
+#### Added
+- **Cross-session decision memory.** An event-sourced (`decide`/`supersede`/`redact`) store at `~/.gstack/projects/<slug>/decisions.jsonl`. "Active" is computed, never a mutable flag, so the history stays honest and tolerant of dangling references.
+- **`gstack-decision-log`** — capture a durable decision, reverse one (`--supersede <id>`), expunge an accidental secret (`--redact <id>`), or rewrite the log to its active set (`--compact`). Non-interactive, injection-sanitized, blocks HIGH and MEDIUM secrets on write.
+- **`gstack-decision-search`** — read active decisions, scope-filtered to the current branch/issue, with `--recent N`, `--scope`, `--query`, `--all`, `--json`. Add `--semantic` (with `--query`) to append related hits from gbrain memory when it is up; it degrades silently to the reliable file results when gbrain is off.
+- **Session-start resurfacing.** Context Recovery shows the scope-relevant active decisions at the top of a session, from a bounded snapshot so it stays fast as the log grows.
+- **Skill capture.** `/plan-ceo-review`, `/plan-eng-review`, `/spec`, and `/ship` record their structured decisions (accepted scope, architecture verdict, filed spec, version bump) automatically.
+- **A `## Cross-session decision memory` section in CLAUDE.md** documenting when and how to capture and resurface.
+- **`/sync-gbrain` call-graph build (`--dream`).** Builds the symbol cross-reference graph behind a lock-free gate, with an honest outcome guard that reports a degraded no-op as WARN rather than a false success.
+
+#### Changed
+- Decision text that resurfaces into agent context is datamarked (code fences, `---` banners, `<|role|>`/`</system>` tags, chat turn-prefixes, and Unicode line terminators are neutralized) so stored text can never masquerade as instructions.
+- `/sync-gbrain` pin guidance is accurate for current gbrain, and the worktree-scoped `.gbrain-source` pin routes code queries correctly.
+
+#### Fixed
+- `/sync-gbrain` no longer wedges forever on a crashed autopilot daemon's stale lock: it reads the holder pid, confirms liveness, and ignores a dead one (it stays conservative when it cannot tell).
+
+#### For contributors
+- New shared `lib/jsonl-store.ts` (injection-reject + atomic single-line append + tolerant read) backs both the learnings and decision stores, so the sanitization path is audited in one place.
+- `lib/bin-context.ts` shares slug/branch/flag plumbing across the decision bins.

+## [1.57.4.0] - 2026-06-08
+
+## **The completeness principle is now Boil the Ocean, matching the post it came from.**
+## **One name across the ETHOS file, every skill, and the developer-profile dial.**
+
+The principle that tells gstack to do the complete thing was called "Boil the Lake" in
+`ETHOS.md` and in every generated skill, with the ocean cast as the anti-pattern. The
+developer-profile system and the completeness intro link already used "boil the ocean"
+as the good, ship-the-whole-thing pole. So the same idea carried two opposite framings
+depending on where you read it. This renames the principle to Boil the Ocean everywhere
+and reframes the metaphor: the ocean is the complete destination, and lakes are the
+boilable units you ship on the way there. The guidance is identical. Only the name and
+the framing prose changed.
+
+### The numbers that matter
+
+Reproduce with `git diff v1.57.3.0..HEAD --stat`.
+
+| Property | Before | After |
+|---|---|---|
+| Principle name in ETHOS + every skill | "Boil the Lake" | "Boil the Ocean" |
+| Name vs. the `scope_appetite` dial ("boil the ocean" = complete) | split | unified |
+| Files updated | — | 63 (ETHOS, CLAUDE, README, resolvers, templates, generated SKILL.md) |
+| Runtime behavior change | — | none, text only |
+
+The one number that matters is zero: no behavior changed. A reviewer reading `ETHOS.md`
+no longer hits "ocean" as the thing to avoid in one section and the thing to aim for in
+the next.
+
+### What this means for you
+
+You get the same complete-the-work recommendations, now under the name from Garry's
+"Boil the Oceans" post. The metaphor reads straight through: the ocean is the goal,
+lakes are how you get there one boil at a time, and only genuinely unrelated
+multi-quarter migrations sit outside scope. Nothing to do on your end.
+
+### Itemized changes
+
+#### Changed
+- `ETHOS.md` section 1 is renamed to "Boil the Ocean" and reframed so the ocean is the
+  complete destination and lakes are the boilable first units, not the ceiling.
+- The "Completeness Principle" header injected into every tier-2+ skill now reads
+  "Boil the Ocean," with prose to match.
+- `CLAUDE.md` and `README.md` references updated to the new name.
+
+#### For contributors
+- Source of the rename lives in the preamble resolvers
+  (`generate-completeness-section.ts`, the `composition.ts` skip-list, and
+  `generate-lake-intro.ts`); all SKILL.md files are regenerated from them.
+- Unit assertions (`skill-validation`, `terse-build`) and the three ship golden
+  fixtures updated to the new header.

 # TODOS
 
+## NEXT PRIORITY
+
+### P1: #1882 — portable skill-install prefix (non-`gstack` install dirs break silently)
+
+**What:** Every generated SKILL.md hardcodes the literal `~/.claude/skills/gstack/...`
+for its `bin/`/asset calls (the per-invocation telemetry/config preamble plus ~9
+resolvers). `setup` wires the top-level skill symlinks for any directory name, so
+installing at `~/.claude/skills/<other>` leaves every internal `bin` reference
+pointing at a non-existent `~/.claude/skills/gstack/` path — failing **silently, at
+skill-invocation time**. Make the emitted references portable: resolve the install
+root at runtime (the preamble already defines `GSTACK_ROOT`/`GSTACK_BIN` in
+`scripts/resolvers/preamble/generate-preamble-bash.ts` but the literals don't use
+them) and emit `$GSTACK_BIN`-relative paths instead of the hardcoded prefix.
+
+**Why:** Filed as #1882. Split out of the June 2026 fix wave (decision A) once
+implementation showed it is a host-config/design change, not a fix-wave patch. The
+urgent half — the guard/freeze/careful frontmatter hooks broken on CC 2.1.162 — was
+already fixed in that wave (#1871) with a literal `$HOME`-anchored path, because
+frontmatter hooks run before any runtime variable exists and cannot use `$GSTACK_BIN`.
+So #1882 is now purely the body-preamble portability work.
+
+**Pros:** Unblocks installs at any directory name; removes a whole class of silent
+invocation-time failures.
+**Cons:** Touches the most load-bearing bash in the repo (every skill's preamble);
+a silent mistake breaks all 52 skills. High blast radius — needs its own focused PR.
+
+**Context / where to start:**

+  emit the literal (`testing.ts`, `review.ts`, `design.ts`, `browse.ts`,
+  `redact-doc.ts`, `tasks-section.ts`, `preamble/generate-*.ts`) to use the
+  preamble-defined `$GSTACK_ROOT`/`$GSTACK_BIN`.
+- Ensure `GSTACK_ROOT`/`GSTACK_BIN` are defined before first use in EVERY skill's
+  preamble (verify the telemetry preamble's first bin call is after the definition).
+- **Test conflict (verified):** `test/gen-skill-docs.test.ts:1942` and the sibling
+  ship assertion currently *assert* generated Claude output `.toContain('~/.claude/skills/gstack')`
+  as a guardrail that Codex-host paths don't leak. These must be rewritten to match
+  the new portable scheme.
+- Regenerate all 52 SKILL.md (`bun run scripts/gen-skill-docs.ts --host all`); never
+  hand-edit generated files. Bisect: resolver/host-config change commit, then the
+  52-file regen commit.
+- Smoke-test a skill invocation from a non-`gstack` install dir to prove the fix.
+- Sibling of #349 (the `$CLAUDE_CONFIG_DIR` / `~/.claude` path issue).

-AI makes completeness cheap. Recommend complete lakes (tests, edge cases, error paths); flag oceans (rewrites, multi-quarter migrations).
+AI makes completeness cheap, so the complete thing is the goal. Recommend full coverage (tests, edge cases, error paths) — boil the ocean one lake at a time. The only thing out of scope is genuinely unrelated work (rewrites, multi-quarter migrations); flag that as separate scope, never as an excuse for a shortcut.
 
 When options differ in coverage, include `Completeness: X/10` (10 = all edge cases, 7 = happy path, 3 = shortcut). When options differ in kind, write: `Note: options differ in kind, not coverage — no completeness score.` Do not fabricate scores.

+AI makes completeness cheap, so the complete thing is the goal. Recommend full coverage (tests, edge cases, error paths) — boil the ocean one lake at a time. The only thing out of scope is genuinely unrelated work (rewrites, multi-quarter migrations); flag that as separate scope, never as an excuse for a shortcut.
 
 When options differ in coverage, include `Completeness: X/10` (10 = all edge cases, 7 = happy path, 3 = shortcut). When options differ in kind, write: `Note: options differ in kind, not coverage — no completeness score.` Do not fabricate scores.

+ * enhancement, never a dependency (the code-search lesson).
+ *
+ * Surface reality (verified against gbrain 0.42.x, not guessed):
+ *  - `gbrain search "<q>"` prints TEXT lines `[score] slug -- snippet`, NOT JSON
+ *    (so we parse the text surface; execGbrainJson would always null here).
+ *  - The curated-memory source is the one whose local_path is the gstack brain

+ *    `gstack-brain-<user>` id. Scoping search to it keeps code/doc corpora out.
