v1.58.4.0 fix: high-priority community bug wave + PTY plan-mode smoke gate (#2077)

* fix(gbrain): stop forcing GBRAIN_PREPARE on transaction-mode poolers (#1965)

buildGbrainEnv auto-set GBRAIN_PREPARE=true whenever DATABASE_URL targeted
port 6543, and the /sync-gbrain capability check exported it for the rest
of the skill run. Both had the semantics inverted: gbrain auto-disables
prepared statements on transaction-mode poolers because they break every
write there ("prepared statement does not exist"); GBRAIN_PREPARE=true is
gbrain's documented override for SESSION-mode poolers on 6543, not a
requirement for transaction mode. The #1435 search symptom the auto-set
worked around was fixed gbrain-side.

Remove both force-sets. A caller-set GBRAIN_PREPARE (either value) still
passes through untouched, preserving the session-mode-on-6543 escape hatch.
isTransactionModePooler stays exported.

* fix(gbrain): classify probe timeout as its own status; sync proceeds instead of skipping (#1964)

The 5s engine probe misclassified healthy-but-slow engines (cold Supabase
pooler connections measured at 6.9-10.7s) as broken-config, so /sync-gbrain
silently skipped code+memory and told the user their config was malformed.

- New "timeout" status: probe killed at the deadline with no recognized
  stderr pattern. Default deadline is now 15s, overridable via
  GSTACK_GBRAIN_PROBE_TIMEOUT_MS (tests set 300ms against a fake that
  sleeps 2s).
- Sync stages PROCEED on timeout with a stderr warning naming the env knob;
  a genuinely-dead engine surfaces its real error at the first operation
  instead of a false config diagnosis.
- Consistency everywhere "ok" gated behavior: gstack-gbrain-detect --is-ok
  exits 0 on timeout, and gen-skill-docs' detection gate accepts it, so a
  slow engine no longer silently suppresses brain-aware features.
- Status cache: key now includes the effective probe timeout (raising it
  invalidates a cached timeout) and GBRAIN_HOME; config detection honors
  GBRAIN_HOME so relocated-home users stop being misclassified as
  missing-config.

* fix(bins): cygpath-normalize SCRIPT_DIR for bun imports; surface learnings-log errors (#1950)

Under Windows git-bash, pwd yields a POSIX path (/c/Users/...) that Bun on
Windows cannot resolve as an ES module specifier. gstack-learnings-log
interpolates SCRIPT_DIR into a bun -e import, so every invocation died with
"Cannot find module" — and 2>/dev/null swallowed the error, silently
dropping every AI-logged learning for Windows users.

- 3-line cygpath -m guard in gstack-learnings-log and gstack-question-log
  (which gains the same import shape in the next commit). Matches the
  duplicated IS_WINDOWS convention in setup; no shared shell lib exists.
- learnings-log adopts question-log's set +e / TMPERR capture pattern
  wholesale: validation errors now print to stderr. The old
  `if [ $? -ne 0 ]` check was dead code under set -euo pipefail — the
  script exited at the failing assignment before reaching it.
- New test/bin-windows-bun-import-paths.test.ts: static invariant (any
  bash bin interpolating $SCRIPT_DIR into a bun -e import must carry the
  guard) + behavioral end-to-end run invoked via `bash <bin>` — added to
  the windows-free-tests workflow list so the conversion is proven on the
  only platform where the bug exists.

* fix(question-log): dedupe INJECTION_PATTERNS via lib/jsonl-store (#1934)

bin/gstack-question-log carried a local copy of the injection-pattern list,
so pattern fixes to lib/jsonl-store.ts never propagated — including the
/override[:\s]/i false-positive fix arriving via community PR #1940.
Import the shared hasInjection instead (enabled by the previous commit's
cygpath guard). question-log also gets the lib's stricter superset
(human:, disregard, from-now-on, approve-all patterns).

Tests pin the contract in a #1940-order-independent way: an "Override:
ignore all previous instructions" header is rejected, "prose overrides the
deterministic table" is accepted, and a static invariant keeps local
INJECTION_PATTERNS duplicates out of the bin.

* fix(security): community-pulse + both dashboards never report fake zeros (#1947)

The security-signaling surface failed open at three layers — every failure
mode read as a reassuring "0 attacks" / "0 installs":

- community-pulse edge function: supabase-js returns {data,error} without
  throwing, and all five queries discarded `error` — a DB outage produced
  real-looking zeros via the SUCCESS path, and the catch (also returning
  zeros with HTTP 200) was unreachable for query failures. Every query now
  destructures and throws; the catch serves the stale cache (marked
  "stale": true) when one exists, else 503 {"error":"pulse_unavailable"}.
  Success responses carry "status":"ok" so clients can distinguish
  authoritative data from legacy backends. NOTE: the edge function deploys
  out-of-band (supabase functions deploy community-pulse).
- gstack-security-dashboard: captures the HTTP status; non-200 / network
  failure / error body / missing section → "unknown — backend error";
  jq missing → "unknown — install jq" (the lossy grep fallback broke on
  nested arrays and under-reported attacks as zero — removed); a 200
  without the new marker shows figures with an "unverified (legacy
  backend)" note. Also fixes a latent display bug: the TOTAL grep matched
  the digit 7 inside "attacks_last_7_days" and misreported every count.
- gstack-community-dashboard: same class — curl || echo "{}" plus
  grep || echo "0" printed "Weekly active installs: 0" on any failure.
  Now "unknown — backend error (HTTP N)".

test/security-dashboard-fallback.test.ts pins the matrix (200+marker,
200-legacy, 503, network failure) x (jq present, jq absent) for both bins:
"unknown" states never render as 0.

* fix(telemetry): redact error_message spans before they leave the machine (#1947)

error_message was uploaded with only quote/newline escaping — stack traces
and failed-API errors can embed credentials, private paths, and hostnames,
and the sync path strips only _repo_slug/_branch.

New lib/redact-engine.ts export redactFindingSpans(): replaces EVERY
finding's span with <REDACTED-{id}> regardless of tier (applyRedactions is
the interactive PII-only path and exits nonzero on credential findings, so
it can't serve machine egress). Returns null when a span can't be located —
callers drop the whole payload rather than risk a leak.

gstack-telemetry-log pipes error_message through it at LOG time, so the
local JSONL at rest is clean too; surrounding text survives for crash
triage. FAIL CLOSED: bun missing, engine error, or non-JSON-string output
all null the field. Tests pin: embedded ghp_ token → <REDACTED-github.pat>
with context intact; redactor unavailable → null; raw bytes on disk never
contain the token.

* fix(redact): prepush guard fails closed on git failure; /ship owns hook install (#1946)

Two gaps closed:

1. Fail closed. The git() helper returned "" on ANY non-zero exit or
   maxBuffer overflow (status null), addedLinesFor produced an empty
   string, and the push sailed through unscanned — fail-open on exactly
   the oversized-diff case where a large secret-bearing blob is most
   likely. The diff call now uses a strict variant that throws; main
   blocks with a clear message naming the GSTACK_REDACT_PREPUSH=skip
   escape valve. Probe calls (symbolic-ref, rev-parse, merge-base) keep
   the permissive helper — their failures are normal control flow.

2. Install path. The hook was installed by nothing ("opt-in, installed by
   nothing" was the issue's words). ./setup runs in the gstack checkout —
   the wrong repo for a per-project hook — so it gets a one-line hint
   only. /ship owns per-repo install: config redact_prepush_hook=true +
   hook missing → silent install (consent already given); config unset +
   no ~/.gstack/.redact-prepush-prompted marker → one-time machine-wide
   AskUserQuestion offer, answer persisted. ship/SKILL.md regenerated in
   this same commit (check-freshness bisect discipline).

Tests: unscannable diff (bogus SHAs) → exit 1 + valve named; empty-but-
successful diff → exit 0; static asserts pin setup as hint-only and the
ship template as the installer surface.

* feat(redact): six new credential patterns — GitLab, HuggingFace, npm, DigitalOcean, Bearer, GCP SA (#1946)

Coverage gaps from the #1946 security review, including token types for
tooling gstack itself drives (glab):

HIGH (block): gitlab.token (glpat-/glptt-/gldt-), huggingface.token (hf_),
npm.token (npm_), digitalocean.token (dop_v1_), gcp.service_account (the
JSON-escaped "private_key" form that dodges pem.private_key's literal-block
match when minified, confirmed by "private_key_id" proximity).

MEDIUM (warn): auth.bearer — the most FP-prone shape in the set (docs are
full of "Authorization: Bearer <token>"), so it requires header-context
proximity and the same entropy>=3.0 + placeholder validator recipe as
env.kv. "Bearer YOUR_TOKEN_HERE" never fires; calibration over coverage,
per the cries-wolf principle.

All shapes are linear-time; test/redact-pattern-lint.test.ts covers them
automatically. Engine tests add positive + placeholder-negative cases per
pattern.

* test: coverage-audit additions for the fix wave

Ship Step 7 gap-fill (all passing, 248 tests across the touched suites):
memory + dream stage probe-timeout proceeds, gbrain-detect override paths,
stale-flag passthrough, 200-body-missing-.security fail-closed case,
telemetry redaction edges, and credential-pattern edge cases.

* fix: pre-landing review fixes

Review army findings (1 critical, auto-fixed with regression tests):

- CRITICAL (security specialist, verified live): redactFindingSpans spliced
  only the regex capture span, and pem.private_key / gcp.service_account
  capture just the BEGIN-header — the key body survived "redaction" and
  shipped via telemetry. Marker-only patterns now drop the whole payload
  (null, fail closed). Overlapping spans (Bearer+JWT on the same bytes) are
  coalesced before splicing so stale offsets can't leave partial secret
  bytes behind.
- gitStrict: drop the dead `|| r.status === null` disjunct (null !== 0
  already covers it); add the signal-kill/null-status regression test the
  docstring promised.
- security-dashboard human mode flags stale snapshots ("figures may be out
  of date") instead of presenting frozen counts as current.
- community-dashboard marker check uses jq when available — the grep-only
  variant misclassified whitespaced/reserialized bodies as legacy.
- telemetry fail-closed test now shadows bun with a failing stub
  (deterministic on any host layout); stale "five status cases" describe
  title renamed.

* fix: adversarial review fixes (Claude + Codex cross-model passes)

Both adversarial passes ran against the wave; every FIXABLE finding landed
with a regression test:

- probeTimeoutMs clamps to >=1ms: a fractional override floored to 0, and
  execFileSync treats timeout:0 as NO timeout — the probe that exists to
  bound hangs could hang forever (found by both models independently).
- /ship silent hook install now requires the hooks dir to live inside
  .git: with core.hooksPath (husky's COMMITTED .husky/), the chaining
  installer would have renamed the team's committed pre-push and written a
  machine-local wrapper into the working tree (found by both models).
- gstack-config gbrain-refresh accepts the "timeout" status — the last
  consumer still gating on literal "ok" (Codex); gstack-gbrain-detect's
  config-derived fields honor GBRAIN_HOME so the detection JSON can't
  report status ok alongside config_exists false (Codex).
- prepush: a remote sha absent locally (shallow clone / stale fetch) falls
  back to the merge-base/empty-tree range — scans MORE, never blocks a
  legitimate push into training users toward --no-verify.
- dashboards: curl's own 000 no longer doubles to "HTTP 000000"; the
  community dashboard flags stale snapshots like the security one; array
  sections parse via jq (the sed/grep loops truncated at the first ']');
  the no-jq marker grep tolerates whitespace.
- telemetry: multi-line redactor output nulls the field instead of
  corrupting the JSONL record; setup's hint fires only when the config key
  is genuinely unset (an explicit false is a recorded decline); the /ship
  prompt marker honors GSTACK_HOME.

Kept as designed (cross-model tension noted): Bearer stays MEDIUM in the
prepush gate — a HIGH Bearer would block every docs example; the entropy
validator can't eliminate that FP class, and MEDIUM warns visibly.

* docs: P1 TODO — eval harness live progress + incremental persistence

Root-caused during this ship: a killed eval run was indistinguishable from a
healthy one for hours (per-file output buffering across mega test files, no
incremental eval-store writes, no honest liveness signal). Full context and
starting points in the entry.

* test: fix operational-learning E2E fixture — copy lib/jsonl-store.ts

Pre-existing breakage, proven on main: gstack-learnings-log has imported
lib/jsonl-store.ts (shared injection patterns) since v1.57.5.0 / #1910, but
the fixture copies only the bin scripts — the bin exits 1 before writing
anything, on main silently (stderr swallowed) and on this branch loudly
(the #1950 error-surfacing made the four-day-old failure visible). A real
install always ships bin/ and lib/ together; the fixture now does too.
Verified: the fixture-shaped invocation writes the learning (exit 0) with
lib present, exits 1 on both main and this branch without it.

* fix(ios-qa): isolate E2E tests under --concurrent (3 real races)

The ios-qa E2E file failed intermittently under `bun test --concurrent`
(the eval harness default). Three distinct shared-state races, all fixed:

1. Shared pidfile: a module-level `workDir` reassigned in beforeEach was
   clobbered by parallel tests, so concurrent daemons collided on the same
   pidfile and the loser returned `already_running`. Each test now gets its
   own dir via makeWorkDir().
2. process.env path globals: tests set GSTACK_IOS_AUDIT_PATH /
   _ATTEMPTS_PATH / _ALLOWLIST_PATH on the shared process env; concurrent
   tests stomped each other's audit/attempts destinations. Threaded
   auditPath/attemptsPath/allowlistPath through DaemonOptions (and
   mintForCaller) as explicit args — env is no longer load-bearing.
3. afterEach cleanup race: the per-test cleanup drained a shared dir array,
   so the first test to finish deleted still-running tests' workDirs
   mid-assertion. Moved to afterAll (cleans once, after all settle).

Verified: 5/5 clean full-suite runs at --max-concurrency 15 (was
intermittent); daemon unit suite 91/91; daemon source compiles. The paths
default to the env-derived locations when options are omitted, so the
production CLI path is unchanged.

* test(pty): pin spawned claude to EVALS model chain (default claude-sonnet-4-6)

launchClaudePty spawned the interactive `claude` TUI with no --model flag, so
the child inherited the operator's ~/.claude/settings.json model. On a
slow-thinking model that meant 5+ min of extended thinking on empty plan-mode
context, timing out the plan-mode smoke tests regardless of contention. Pin the
model via opts.model ?? EVALS_MODEL ?? 'claude-sonnet-4-6' — byte-identical to
session-runner.ts:144, so PTY and `claude -p` evals always agree.

Pushed before extraArgs (last flag wins, so a per-test --model still overrides).
Placement leaves the spawn region byte-stable for a clean merge with the
in-flight hermetic-env branch. Plumbed model through the three plan-skill
wrappers. Static-grep tripwires guard the pin, its fallback chain, the
before-extraArgs ordering, and all three wrapper forwards.

* test(pty): detect markdown bold-bullet prose AUQs (fixes office-hours smoke)

office-hours auto-mode renders its mode question as `- **Building a startup**`
markdown bullets (office-hours/SKILL.md.tmpl:102) with no letter/number marker.
isProseAUQVisible only matched `A)`-style lettered or `1.`-style numbered
options, so the question went undetected: the model surfaced it at ~2m19s
(well under the 300s budget) but the harness kept scoring the run "working"
off the spinner glyphs and timed out — a false timeout on a question that was
already on screen.

Add Pattern 3: when an interrogative line ('?') is present AND 3+ bold-bullet
markers (`- **`) appear in the 4KB tail, classify as a prose AUQ. Bold is the
discriminator vs incidental prose bullets; the line anchor is dropped (stripAnsi
can collapse option lines) and the existing `❯ 1.` cursor gate still defers to a
live native list. Wires through the existing classifyVisible 'asked' path and the
timeout high-water-mark, so office-hours now classifies 'asked' instead of
'timeout'. Five unit cases: the office-hours render passes; no-'?', <3-bullet,
plain-bullet, and native-cursor cases stay false.

* test(pty): detect stripAnsi-collapsed prose AUQs + judge spinner-precedence

The plan-eng/plan-design plan-mode + finding-floor smokes timed out even when
the skill HAD rendered a complete prose AskUserQuestion and was waiting: the PTY
strips cursor-positioning escapes, collapsing the option newlines/spaces so
"A) ..." arrives as "A(recommended)" / "-B:" and "Reply with A, B, or C" as
"ReplywithA,B,orC". Every line-anchored detector (Patterns 1-3) returns false on
those bytes, so proseAUQEverObserved never latched and the run timed out on a
question that was already on screen.

Add Pattern 4/5: a two-signal collapsed-form detector — a reply/recommendation
marker (space-insensitive "reply with [A-D]", "Recommendation:", or
"(recommended)") AND 2+ distinct A-D letters each punctuated by ) : or (. The
conjunction is what separates a real AUQ from incidental report prose; verified
true on the verbatim failing-run buffers where Patterns 1-3 return false.

Also fix the Haiku judge spinner bias: of 614 verdicts, 569 were 'working' and
95 of those noted a question was visible — Claude Code keeps the spinner
animating at an idle prose decision, so the judge coin-flipped. Add a precedence
override: when an option list AND a Recommendation/Reply instruction are both
visible, classify WAITING even with spinner glyphs. Kept the strict dual-signal
gate (never option-list-alone) so auto-decide-preserved doesn't flip.

5 unit tests pin the two-signal contract (2 true on real collapsed bytes, 3
false guards). 90 -> 95 pass.

* feat(plan-review): ask-first scope gate for plan-eng + plan-design review

On an empty/cold invocation, plan-eng-review and plan-design-review would dive
straight into repo exploration (plan-eng) or a 7-pass mockup+audit (plan-design)
and only ask the user much later, if at all. plan-ceo-review already asks first
via an unconditional Step-0 gate and behaves well; these two did not.

Add a hard-STOP scope gate as the FIRST operational instruction in each skill
(above the design-doc check / pre-review audit / mockup defaults it explicitly
overrides): the first tool call must be AskUserQuestion confirming the review
target, before any git/Read/Grep/Glob/Bash or mockup generation. Under
--disallowedTools the options render as plain column-0 lettered prose with a
Recommendation + "Reply with A, B, or C" line so the answer is detectable.

This is correct cold-start UX (confirm what to review before grinding a full
review on nothing) and it is the product half of the plan-mode smoke fix; the
harness collapsed-form detector is the deterministic half that catches the ask
however it renders. Templates + regenerated SKILL.md (default variant).

* test(tiers): reclassify stochastic plan-eng/plan-design ask-first smokes as periodic

plan-eng-review and plan-design-review run a long explore/audit before their
first AskUserQuestion, so whether the plan-mode + finding-floor smokes reach a
terminal outcome within the 300s/600s budget depends on stochastic ask-first
compliance (measured ~50-67%/run even with the hardened gate). Per the
"non-deterministic -> periodic" tiering rule, move the four affected smokes
(plan-eng/plan-design review-plan-mode + finding-floor) to periodic.

The deterministic harness fix (collapsed-form detector + judge precedence) and
the ask-first gate lift these from always-failing to mostly-passing and are the
real product+harness improvements; periodic monitoring tracks the rate weekly
without blocking PRs on an LLM coin-flip. plan-ceo/plan-devex ask-first reliably
and stay gate-tier.

* ci(evals): gate the deterministic PTY plan-mode smokes in CI

The real-PTY plan-mode smokes never ran in CI — the gate was local-only. Add an
e2e-pty-plan-smoke matrix suite running the two deterministically-reliable ones
(office-hours-auto-mode, plan-mode-no-op) so a regression there blocks PRs. The
stochastic plan-eng/plan-design ask-first smokes stay periodic (touchfiles
E2E_TIERS) and are not CI-gated.

A fresh CI container has no ~/.claude.json, so the spawned interactive `claude`
would wedge on the onboarding + API-key-approval dialog. Add a scoped seed step
(hasCompletedOnboarding + key approval, its own ANTHROPIC_API_KEY env) before the
run — mirrors what the hermetic E2E child env seeds. Per-suite timeout override
(35 min) via matrix.suite.timeout so the PTY suite has headroom for --retry 2
without bumping the other 12 suites. Report runner count 12 -> 13.

Validate via workflow_dispatch before relying on the gate (PTY-in-CI is new).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* ci(evals): install gstack skill registry for the PTY smoke suite

The first dry-run of e2e-pty-plan-smoke failed: the spawned interactive `claude`
printed "Unknown command: /plan-ceo-review". .claude/skills is gitignored, so a
fresh CI checkout has no gstack skill registry and the TUI can't resolve
/office-hours or /plan-ceo-review.

Add a Register step (scoped to the suite, after Seed, before Run) that mirrors
setup's --no-prefix user-scoped registry minimally: $HOME/.claude/skills/gstack
-> repo (resolves the preambles' absolute ~/.claude/skills/gstack/bin/* and
<skill>/sections/* paths) + per-skill SKILL.md/sections symlinks for the two
skills these tests invoke. HOME is /github/home in this container and the runner
adds no HOME/CLAUDE_CONFIG_DIR override (no hermetic mode), so $HOME is the right
anchor — the Seed step already proved claude reads it. No ./setup (binary build
+ Chromium + fonts + /dev/tty prompt); SKILL.md + bin/ + sections/ are committed.

Self-validating: fails the step loudly on a dangling symlink or missing
`name:` frontmatter, so a moved target surfaces here instead of as a silent
35-min "Unknown command" timeout.

 # Changelog
 
+## [1.58.4.0] - 2026-06-18
+
+## **A community bug-fix wave plus a test-gate that finally sees the questions it was missing.**
+## **gbrain writes survive transaction-mode poolers, the redaction engine learns six more secret shapes, dashboards stop lying about zero, and the plan-review smokes detect asks the harness was blind to.**
+
+Two things ship here. First, the high-priority community bug wave: gbrain stopped force-enabling `GBRAIN_PREPARE` on transaction-mode poolers (which broke 100% of writes), a slow-but-healthy probe now classifies as `timeout` and lets sync proceed instead of silently skipping, the redaction engine gained six credential patterns, telemetry `error_message` runs through redaction before it leaves the machine, both the security and community dashboards stop reporting a fake `0` when the backend errors, and the Windows git-bash bins resolve their imports. Second, the plan-mode test gate: the real-PTY smokes for `/plan-eng-review`, `/plan-design-review`, and `/office-hours` were timing out on questions the skills had already rendered, because the terminal strips the cursor escapes that lay out the options. A new collapsed-form detector catches the ask in any render, the Haiku state-judge stops coin-flipping on a leftover spinner, and `/plan-eng-review` + `/plan-design-review` now confirm what to review before grinding a full audit on an empty repo.
+
+### The numbers that matter
+
+From the v1.58.4.0 diff against main and the CI eval matrix (`.github/workflows/evals.yml`, run 27780530109).
+
+| Metric | Before | After | Δ |
+|--------|--------|-------|---|
+| Credential shapes the redaction engine catches | (prior set) | +6 (GitLab, HuggingFace, npm, DigitalOcean, Bearer, GCP SA) | +6 |
+| Dashboards that can print a fake `0` on a backend error | 2 | 0 | -2 |
+| gstack skills whose gbrain writes break on a 6543 pooler | all | 0 | fixed |
+| PTY plan-mode smokes that timed out on an already-rendered question | 3 | 0 | -3 |
+| Reliably-green PTY smokes actually gated in CI | 0 | 4 | +4 |
+
+`office-hours` rendered its mode question at ~2m19s, well under the 300s budget, and the harness still scored the run a timeout because the option lines arrived collapsed (`A)` as `A(recommended)`, `Reply with A, B, or C` as `ReplywithA,B,orC`). The detector now reads both forms; 95 unit tests pin its contract.
+
+### What this means for gstack users
+
+If you run gbrain on a Supabase transaction-mode pooler, your writes work again. If you use `/ship`'s pre-push guard, it now fails closed on a git error and catches six more credential types before they leave your machine. If you run `/plan-eng-review` or `/plan-design-review`, they ask what to review first instead of spelunking your whole repo. The plan-review test gate stops flaking on its own blind spot. Nothing to do but upgrade.
+
+### Itemized changes
+
+#### Fixed
+- **gbrain on transaction-mode poolers:** removed the forced `GBRAIN_PREPARE=true` that deterministically broke writes on port-6543 poolers (#1965). An explicit user-set `GBRAIN_PREPARE` still passes through.
+- **gbrain probe timeout:** a probe that exceeds its deadline classifies as its own `timeout` status (15s default, `GSTACK_GBRAIN_PROBE_TIMEOUT_MS`-overridable); sync proceeds with a warning instead of silently suppressing brain features for a slow-but-healthy engine (#1964).
+- **Security + community dashboards:** backend errors now surface as "unknown — backend error" (or a 503), never a fake `0`; success responses carry a `status:"ok"` marker so legacy backends are flagged "unverified" (#1947).
+- **Telemetry:** `error_message` passes through the redaction engine at log time; on a redactor failure it fails closed to null (#1947).
+- **Windows git-bash:** `gstack-learnings-log` and `gstack-question-log` cygpath-normalize `$SCRIPT_DIR` so their `bun -e` imports resolve; learnings-log surfaces validation errors instead of swallowing them (#1950).
+- **`gstack-question-log`:** shares the audited injection-pattern list from `lib/jsonl-store.ts` instead of a local duplicate (#1934).
+- **Pre-push guard:** fails closed when the diff cannot be computed (git failure / maxBuffer kill), with a `GSTACK_REDACT_PREPUSH=skip` escape valve (#1946).
+- **PTY plan-mode smokes:** the harness detects a rendered AskUserQuestion even when stripAnsi collapses the option lines (markdown bold-bullet and lettered/numbered prose forms); the Haiku state-judge classifies WAITING when a question + reply-instruction is on screen despite an animating spinner. Fixes the office-hours, plan-eng, and plan-design plan-mode smokes that timed out on questions already displayed.
+- **ios-qa E2E:** isolated under `bun test --concurrent` (per-test work dirs, daemon paths passed as options not process-global env, afterAll cleanup) — fixes 3 real races.
+
+#### Added
+- **Six credential patterns in the redaction engine:** GitLab tokens, HuggingFace, npm, DigitalOcean, `Bearer` (entropy-gated), and GCP service-account JSON (#1946).
+- **Ask-first scope gate** in `/plan-eng-review` and `/plan-design-review`: the first action confirms the review target (branch diff / pasted plan / specific path) before any repo exploration or audit.
+- **`/ship` owns the pre-push guard install:** silent auto-install when the repo opts in, a one-time offer otherwise (#1946).
+
+#### For contributors
+- New collapsed-form prose-AUQ detector + judge spinner-precedence rule in `test/helpers/claude-pty-runner.ts`; 95 unit tests pin the two-signal contract.
+- The PTY model now pins to `EVALS_MODEL ?? claude-sonnet-4-6` (mirrors `session-runner.ts`), removing operator-model nondeterminism from the smokes.
+- Stochastic ask-first smokes (plan-eng/plan-design plan-mode + finding-floor) reclassified `periodic` per the non-deterministic-tests rule; the deterministic ones (office-hours, plan-mode-no-op) now run in CI via a new `e2e-pty-plan-smoke` matrix suite with an in-container skill-registry install step.
+- `redactFindingSpans()` is the machine-egress redaction entry point in `lib/redact-engine.ts`.

 ## Test infrastructure
 
+### Eval harness: live progress + incremental result persistence (kill the silent hour)
+
+**Priority:** P1
+
+**What:** `bun run test:evals` is observably silent for its entire runtime and
+persists nothing until completion. Make the E2E harness (1) append a one-line
+progress record per test START and END to a well-known heartbeat file (e.g.
+`~/.gstack-dev/evals/.current-run.jsonl`), (2) write each test's eval-store
+result incrementally instead of only at run end, and (3) flush per-test
+pass/fail lines to stderr unbuffered so `bun test --concurrent` mega-file
+buffering can't hide 50 minutes of legitimate progress.
+
+**Why:** During the v1.57.11.0 ship, the diff-selected eval run (54 tests) was
+killed ~50 min in and NOTHING distinguished the corpse from a healthy run for
+hours: the log had zero test lines (per-file buffering across five mega
+`skill-e2e-*.test.ts` files), `~/.gstack-dev/evals/` had zero new files
+(results persist only on completion), and the only available liveness signal
+(`pgrep "bun test --max-concurrency"`) false-positives on every sibling
+free-suite shard. An agent or human watching the run has no honest signal.
+
+**Pros:** Dead runs detected in minutes instead of hours; partial results
+survive kills (a 50-min run that dies at test 40/54 keeps 40 results and can
+resume); `eval:watch` gets a real data source.
+
+**Cons:** Touches `test/helpers/session-runner.ts` + `eval-store.ts` (global
+touchfiles — change triggers ALL eval tests on the next diff-selected run);
+incremental writes need a PARTIAL marker so `eval:compare` doesn't treat a
+dead run as a complete baseline.
+
+**Context:** Root-caused 2026-06-12 during the v1.57.11.0 /ship. The run
+itself was on pace (~50 min for 54 E2E tests at concurrency 15 is nominal);
+the failure was pure observability. Related: the existing
+`project_e2e_harness_observability` note (stream-json reasoning + tool traces
+dropped on failure — same module, fix together). Start in
+`test/helpers/session-runner.ts` (per-test lifecycle) and
+`test/helpers/eval-store.ts` (persistence timing).
+
+**Depends on / blocked by:** Nothing. Classify the new behavior under the
+existing two-tier system; the heartbeat file must be safe under
+`--concurrent` (append-only, one JSON line per event).
+
 ### ✅ DONE (v1.53.1.0): Rebaseline parity-suite (v1.44.1 → v1.53.0.0)

 Before reviewing anything, answer these questions:
 1. **What existing code already partially or fully solves each sub-problem?** Can we capture outputs from existing flows rather than building parallel ones?
 2. **What is the minimum set of changes that achieves the stated goal?** Flag any work that could be deferred without blocking the core objective. Be ruthless about scope creep.

 Before reviewing anything, answer these questions:
 1. **What existing code already partially or fully solves each sub-problem?** Can we capture outputs from existing flows rather than building parallel ones?
 2. **What is the minimum set of changes that achieves the stated goal?** Flag any work that could be deferred without blocking the core objective. Be ruthless about scope creep.

+ * $SCRIPT_DIR into a `bun -e` import must normalize it via `cygpath -m`
+ * first, or the bin exits 1 with "Cannot find module" — which, combined
+ * with stderr swallowing, silently dropped every AI-logged learning.
+ *
+ * Two layers:
+ *   1. Static invariant — every bash bin with a $SCRIPT_DIR bun-import
+ *      interpolation carries the cygpath guard (catches future bins).
+ *   2. Behavioral — gstack-learnings-log, invoked the way Windows CI
+ *      invokes bash bins (spawnSync("bash", [path])), writes a learning
+ *      and surfaces validation errors on stderr instead of swallowing
+ *      them. This file is in the windows-free-tests workflow list, so the

+ * #1947 — security/community dashboards must never report fake zeros.
+ *
+ * A backend failure, a network failure, or a missing jq used to degrade to
+ * "0 attacks" / "Weekly active installs: 0" — indistinguishable from a
+ * genuinely healthy reading on a security-signaling surface. The contract
+ * pinned here:
+ *
+ *   - non-200 / network failure / error body  → "unknown", never 0
+ *   - jq missing (security dashboard)         → "unknown — install jq", never 0
+ *   - 200 with the new backend's status:"ok"  → figures trusted
+ *   - 200 without the marker (legacy backend) → figures shown + "unverified" note
+ *
+ * curl is stubbed via a prepended PATH; the jq-missing case runs with a
+ * PATH containing only the stub + whitelisted tools (no jq).
