feat: bug fix wave v1.36.0.0 — Implementation Tasks, allowlist patterns, surrogate-safe page captures (#1440 #1452 #1454)

Three filed issues land together:

#1440 — Page captures from real-world HTML hit 'API Error 400: no low
surrogate in string'. Sanitizers + buildCommandResponse extraction shipped in
the prior commit; this commit adds the migration script that patches existing
brain-allowlist/privacy-map/gitattributes installs and the supporting tests.

#1452 — Federation sync was silently skipping root-level design and test-plan
docs. bin/gstack-artifacts-init adds two patterns to all three managed blocks
(.brain-allowlist, .brain-privacy-map.json, .gitattributes). Idempotent
migration v1.36.0.0.sh repairs existing installs in place via jq (preserves
JSON validity) — no commit + push from the migration.

#1454 — All four review skills (CEO/design/eng/DX) emit an Implementation
Tasks markdown section AND write a jq-built JSONL artifact per phase.
/autoplan reads all four files, scopes by current branch + 5-commit window,
dedupes on exact (component, sorted(files), title), and renders an aggregated
list in the Final Approval Gate.

New tests:
- browse/test/sanitize.test.ts (18 cases)
- browse/test/build-command-response.test.ts (7 cases)
- test/artifacts-init-migration.test.ts (7 cases)

VERSION → 1.36.0.0. Skips the v1.34.x slot taken by 'gstack consumable as
submodule' and the v1.35.0.0 slot taken by /document-generate. #1428 was
shipped separately by v1.34.2.0 with a different approach; follow-up #1503
filed for the bare-path filesystem boundary concern surfaced during our
analysis.

# Changelog
## [1.36.0.0] - 2026-05-14
## **Page captures stop crashing on broken emoji bytes, every review skill ends with a build-actionable task checklist, federation sync no longer drops office-hours design docs.**
## **Three community-filed issues landed as one bug-fix wave: surrogate-safe browse responses (including `/batch`), per-skill Implementation Tasks with JSONL handoff to `/autoplan`, and root-level artifact patterns in `.brain-allowlist`.**
Page captures from real-world HTML hit `API Error 400: no low surrogate in string` when a page contains unpaired Unicode surrogate bytes (broken emoji, mid-character splits). Browse now sanitizes at the response chokepoint (`buildCommandResponse` in `server.ts`) AND at the `/batch` envelope, with separate utilities for raw UTF-16 surrogates and `\uXXXX` JSON escape sequences. Defense in depth wraps the highest-volume DOM-text emitters (`text`, `html`, `accessibility`, `snapshot`) at extraction time too. Every command response is now safe to JSON.stringify for the Claude API; the bug surfaces from `$B html`, `$B accessibility`, and `$B batch` are all closed, not just `$B text`. The chokepoint refactor extracts `buildCommandResponse` from `handleCommand` so the boundary is unit-testable without spinning up the server.
All four review skills (CEO / design / eng / DX) now end with an `## Implementation Tasks` markdown checklist and write a `jq`-built JSONL artifact to `~/.gstack/projects/$SLUG/tasks-{phase}-{datetime}.jsonl`. `/autoplan`'s Phase 4 reads all four files, scopes by current branch + 5-commit window, dedupes on exact `(component, sorted(files), title)` matches, and renders one aggregated list inside the final approval gate. Tasks that derive from the same finding now collapse; tasks that just happen to touch the same file with different titles surface separately so the human can decide whether they're the same work. Standalone review runs (`/plan-eng-review` alone, etc.) produce their own task list and JSONL file even outside autoplan — the JSONL is the handoff contract.
Federation sync (`gstack-brain-sync`) was silently skipping root-level design and test-plan docs — `/office-hours` and `/plan-eng-review` write at `projects/{slug}/{user}-{branch}-design-*.md`, but the allowlist only knew about `projects/*/designs/*.md` and `projects/*/ceo-plans/*.md`. New patterns ship in `.brain-allowlist`, `.brain-privacy-map.json` (classified as `artifact`), and `.gitattributes` (with `merge=union` to handle cross-machine conflicts). An idempotent jq-based migration (`gstack-upgrade/migrations/v1.36.0.0.sh`) patches existing installs in-place without re-running `gstack-artifacts-init` (which would have done a git commit + push and clobbered user state).
### The numbers that matter
Source: `bun test browse/test/sanitize.test.ts browse/test/build-command-response.test.ts test/artifacts-init-migration.test.ts` — 32 new unit tests covering every fix surface, all green.
| Surface | Before | After |
|---|---|---|
| API 400 from `$B text` on surrogate-containing page | Crash | Sanitized at extraction + chokepoint |
| API 400 from `$B html`, `$B accessibility`, `$B batch` | Crash (chokepoint bypassed) | Sanitized at `buildCommandResponse` + `/batch` envelope |
| Application/json bodies with `\uXXXX` escape surrogates | Still crash (regex matches raw codepoints only) | Second-pass `stripLoneSurrogateEscapes` handles escape text |
| `/autoplan` final output | Decision summary, no task list | Decision summary **plus** aggregated `Implementation Tasks` from all 4 phases |
| Standalone `/plan-eng-review` output | Required-outputs sections, no task list | Same **plus** per-skill `Implementation Tasks` + JSONL handoff |
| `/office-hours` design docs in federation queue | Silently skipped (root-level not in allowlist) | Queued, classified `artifact`, union-merge rule applied |
| Lone surrogate sanitizer perf on 1MB clean text | n/a | <500ms (single regex pass) |
| `buildCommandResponse` testability | Embedded inside `handleCommand`, not exported | Extracted, exported, 7 unit tests cover it |
### What this means for builders
Page captures with mixed-script Unicode round-trip cleanly to the Claude API now. Every review skill you run ends with a checkbox list of build tasks you can hand to Claude Code or Codex. Federation sync picks up the design docs that were silently dropping out of your brain repo. Run `/gstack-upgrade` to pick up the migration that patches your `.brain-allowlist`, `.brain-privacy-map.json`, and `.gitattributes` in place; no commit + push, no user-state clobber.
### Itemized changes
#### Fixed
- **Page-capture API 400 from lone Unicode surrogates (#1440)**`browse/src/sanitize.ts` (new) exports `stripLoneSurrogates`, `stripLoneSurrogateEscapes`, and `sanitizeBody`. `buildCommandResponse` (extracted from `handleCommand`, now exported for testability) sanitizes every text/plain and application/json response body. `/batch` was bypassing this chokepoint (`server.ts:1841,1869`); each per-result string is now sanitized AND the final envelope gets a second pass on the JSON-escape form. Defense in depth wraps at `getCleanText`, `getCleanTextWithStripping`, `html`, `accessibility`, and `snapshot` extraction sites.
- **Federation sync drops `/office-hours` and `/plan-eng-review` artifacts (#1452)**`bin/gstack-artifacts-init` adds `projects/*/*-design-*.md` and `projects/*/*-test-plan-*.md` to all three managed blocks: `.brain-allowlist`, `.brain-privacy-map.json` (class `artifact`), and `.gitattributes` (`merge=union`).
- **`/setup-gbrain` wrong config key (#1441)** — verified already-fixed in v1.27.0.0; closed the issue with a comment citing the migration script that aligns legacy `gbrain_sync_mode` installs to the current `artifacts_sync_mode` key.
#### Added
- **`## Implementation Tasks` section + JSONL handoff in every review skill (#1454)** — `plan-ceo-review`, `plan-design-review`, `plan-eng-review`, `plan-devex-review` each emit a per-skill markdown checklist and write `~/.gstack/projects/$SLUG/tasks-{phase}-{datetime}.jsonl` via `jq -nc` (never hand-rolled echo). `/autoplan` Phase 4 reads all four phase JSONL files, scopes by current branch and 5-commit window, dedupes on exact `(component, sorted(files), title)` matches, and renders one aggregated list. Near-duplicates surface separately with a possible-duplicate note for human resolution.
- **`browse/src/sanitize.ts`** — two surrogate-stripping utilities plus a convenience selector keyed on content-type. Pairs with a refactored `buildCommandResponse` in `server.ts` (exported for testability) and per-result sanitization in the `/batch` handler.
- **`gstack-upgrade/migrations/v1.36.0.0.sh`** — idempotent per-file repair for `.brain-allowlist`, `.brain-privacy-map.json`, and `.gitattributes`. Uses `jq` for the JSON file (preserves validity); falls back with a clear warning if `jq` is missing. Does NOT re-run `gstack-artifacts-init` (which would commit + push to the user's federated repo).
- **32 new unit tests** across `browse/test/sanitize.test.ts` (18), `browse/test/build-command-response.test.ts` (7), `test/artifacts-init-migration.test.ts` (7). All gate-tier (free, runs on every PR).
#### Changed
- **`browse/src/snapshot.ts`, `read-commands.ts`, `content-security.ts`** — defense-in-depth surrogate wraps at extraction sites that feed pre-Response consumers (datamarking, envelope wrapping).
- **`scripts/resolvers/tasks-section.ts`** (new) + **`scripts/task-emission-schema.ts`** (new) — shared resolver and schema for the per-skill task emission. Each review template invokes `{{TASKS_SECTION_EMIT:<phase>}}` once.
#### For contributors
- `/codex review` on Codex CLI ≥0.130.0 was handled separately by v1.34.2.0 (the dual-path bare/exec approach). Our planning surfaced an adjacent concern: the bare path no longer carries the filesystem boundary, so codex may waste tokens reading skill files when the diff happens to touch `.claude/skills/`. Filed as a follow-up issue; not blocking this release.
- The implementation-tasks aggregation in `/autoplan` uses a structured JSONL handoff between phases rather than re-parsing markdown. Schema lives in `scripts/task-emission-schema.ts`. Adding a fifth review phase means adding the phase name to `VALID_PHASES` in `scripts/resolvers/tasks-section.ts` and including `{{TASKS_SECTION_EMIT:<phase-name>}}` in the new review template.
- Touchfiles entries are unchanged — the new tests are all gate-tier unit tests that run on `bun test`. Touchfiles is only for E2E + LLM evals.
## [1.35.0.0] - 2026-05-13
## **Docs become a tracked surface, not an afterthought. `/document-generate` writes them from scratch, `/document-release` audits coverage in four Diataxis quadrants.**

Before closing this review, synthesize the findings above into a flat list of

### Markdown section (always emit)
\`\`\`markdown
## Implementation Tasks
Synthesized from this review's findings. Each task derives from a specific
finding above. Run with Claude Code or Codex; checkbox as you ship.
- [ ] **T1 (P1, human: ~2h / CC: ~15min)** <component> <imperative title>
- Surfaced by: <section name> <specific finding text or line reference>
- Files: <paths to touch>
- Verify: <test command or manual check>
- [ ] **T2 (P2, human: ~30min / CC: ~5min)** ...

Rules:
- P1 blocks ship; P2 should land same branch; P3 is a follow-up TODO.
- If a finding produced no actionable task, do not invent one.
- If a section had zero findings, emit \`_No new tasks from <section>._\`
- Effort uses the AI-compression table from CLAUDE.md.
### JSONL artifact (always write, even if zero tasks)
\`/autoplan\` reads this file to aggregate across phases. Build each line with
\`jq -nc\` so titles and source findings containing quotes, newlines, or
backslashes serialize cleanly never use hand-rolled \`echo\` / \`printf\`.

If \`jq\` is not installed, fall back to skipping the JSONL write and warn
the user to install jq for autoplan aggregation. Never hand-roll JSONL.
If zero tasks were identified in this review, still touch the JSONL file
(\`: > "$TASKS_FILE"\`) so the aggregator sees that the phase produced output
this run (an empty file means "ran, no findings" distinct from "didn't run").
