# TODOS

## Builder Ethos

### First-time Search Before Building intro

**What:** Add a `generateSearchIntro()` function (like `generateLakeIntro()`) that introduces the Search Before Building principle on first use, with a link to the blog essay.

**Why:** Boil the Lake has an intro flow that links to the essay and marks `.completeness-intro-seen`. Search Before Building should have the same pattern for discoverability.

**Context:** Blocked on a blog post to link to. When the essay exists, add the intro flow with a `.search-intro-seen` marker file. Pattern: `generateLakeIntro()` at gen-skill-docs.ts:176.

**Effort:** S
**Priority:** P2
**Depends on:** Blog post about Search Before Building

## Chrome DevTools MCP Integration

### Real Chrome session access

**What:** Integrate Chrome DevTools MCP to connect to the user's real Chrome session with real cookies, real state, no Playwright middleman.

**Why:** Right now, headed mode launches a fresh Chromium profile. Users must log in manually or import cookies. Chrome DevTools MCP connects to the user's actual Chrome ... instant access to every authenticated site. This is the future of browser automation for AI agents.

**Context:** Google shipped Chrome DevTools MCP in Chrome 146+ (June 2025). It provides screenshots, console messages, performance traces, Lighthouse audits, and full page interaction through the user's real browser. gstack should use it for real-session access while keeping Playwright for headless CI/testing workflows.

Potential new skills:
- `/debug-browser`: JS error tracing with source-mapped stack traces
- `/perf-debug`: performance traces, Core Web Vitals, network waterfall

May replace `/setup-browser-cookies` for most use cases since the user's real cookies are already there.

**Effort:** L (human: ~2 weeks / CC: ~2 hours)
**Priority:** P0
**Depends on:** Chrome 146+, DevTools MCP server installed

## Browse

### Bundle server.ts into compiled binary

**What:** Eliminate `resolveServerScript()` fallback chain entirely — bundle server.ts into the compiled browse binary.

**Why:** The current fallback chain (check adjacent to cli.ts, check global install) is fragile and caused bugs in v0.3.2. A single compiled binary is simpler and more reliable.

**Context:** Bun's `--compile` flag can bundle multiple entry points. The server is currently resolved at runtime via file path lookup. Bundling it removes the resolution step entirely.

**Effort:** M
**Priority:** P2
**Depends on:** None

### Sessions (isolated browser instances)

**What:** Isolated browser instances with separate cookies/storage/history, addressable by name.

**Why:** Enables parallel testing of different user roles, A/B test verification, and clean auth state management.

**Context:** Requires Playwright browser context isolation. Each session gets its own context with independent cookies/localStorage. Prerequisite for video recording (clean context lifecycle) and auth vault.

**Effort:** L
**Priority:** P3

### Video recording

**What:** Record browser interactions as video (start/stop controls).

**Why:** Video evidence in QA reports and PR bodies. Currently deferred because `recreateContext()` destroys page state.

**Context:** Needs sessions for clean context lifecycle. Playwright supports video recording per context. Also needs WebM → GIF conversion for PR embedding.

**Effort:** M
**Priority:** P3
**Depends on:** Sessions

### v20 encryption format support

**What:** AES-256-GCM support for future Chromium cookie DB versions (currently v10).

**Why:** Future Chromium versions may change encryption format. Proactive support prevents breakage.

**Effort:** S
**Priority:** P3

### State persistence — SHIPPED

~~**What:** Save/load cookies + localStorage to JSON files for reproducible test sessions.~~

`$B state save/load` ships in v0.12.1.0. V1 saves cookies + URLs only (not localStorage, which breaks on load-before-navigate). Files at `.gstack/browse-states/{name}.json` with 0o600 permissions. Load replaces session (closes all pages first). Name sanitized to `[a-zA-Z0-9_-]`.

**Remaining:** V2 localStorage support (needs pre-navigation injection strategy).
**Completed:** v0.12.1.0 (2026-03-26)

### Auth vault

**What:** Encrypted credential storage, referenced by name. LLM never sees passwords.

**Why:** Security — currently auth credentials flow through the LLM context. Vault keeps secrets out of the AI's view.

**Effort:** L
**Priority:** P3
**Depends on:** Sessions, state persistence

### Iframe support — SHIPPED

~~**What:** `frame <sel>` and `frame main` commands for cross-frame interaction.~~

`$B frame` ships in v0.12.1.0. Supports CSS selector, @ref, `--name`, and `--url` pattern matching. Execution target abstraction (`getActiveFrameOrPage()`) across all read/write/snapshot commands. Frame context cleared on navigation, tab switch, resume. Detached frame auto-recovery. Page-only operations (goto, screenshot, viewport) throw clear error when in frame context.

**Completed:** v0.12.1.0 (2026-03-26)

### Semantic locators

**What:** `find role/label/text/placeholder/testid` with attached actions.

**Why:** More resilient element selection than CSS selectors or ref numbers.

**Effort:** M
**Priority:** P4

### Device emulation presets

**What:** `set device "iPhone 16 Pro"` for mobile/tablet testing.

**Why:** Responsive layout testing without manual viewport resizing.

**Effort:** S
**Priority:** P4

### Network mocking/routing

**What:** Intercept, block, and mock network requests.

**Why:** Test error states, loading states, and offline behavior.

**Effort:** M
**Priority:** P4

### Download handling

**What:** Click-to-download with path control.

**Why:** Test file download flows end-to-end.

**Effort:** S
**Priority:** P4

### Content safety

**What:** `--max-output` truncation, `--allowed-domains` filtering.

**Why:** Prevent context window overflow and restrict navigation to safe domains.

**Effort:** S
**Priority:** P4

### Streaming (WebSocket live preview)

**What:** WebSocket-based live preview for pair browsing sessions.

**Why:** Enables real-time collaboration — human watches AI browse.

**Effort:** L
**Priority:** P4

### Headed mode with Chrome extension — SHIPPED

`$B connect` launches Playwright's bundled Chromium in headed mode with the gstack Chrome extension auto-loaded. `$B handoff` now produces the same result (extension + side panel). Sidebar chat gated behind `--chat` flag.

### `$B watch` — SHIPPED

Claude observes user browsing in passive read-only mode with periodic snapshots. `$B watch stop` exits with summary. Mutation commands blocked during watch.

### Sidebar scout / file drop relay — SHIPPED

Sidebar agent writes structured messages to `.context/sidebar-inbox/`. Workspace agent reads via `$B inbox`. Message format: `{type, timestamp, page, userMessage, sidebarSessionId}`.

### Multi-agent tab isolation

**What:** Two Claude sessions connect to the same browser, each operating on different tabs. No cross-contamination.

**Why:** Enables parallel /qa + /design-review on different tabs in the same browser.

**Context:** Requires tab ownership model for concurrent headed connections. Playwright may not cleanly support two persistent contexts. Needs investigation.

**Effort:** L (human: ~2 weeks / CC: ~2 hours)
**Priority:** P3
**Depends on:** Headed mode (shipped)

### Chrome Web Store publishing

**What:** Publish the gstack browse Chrome extension to Chrome Web Store for easier install.

**Why:** Currently sideloaded via chrome://extensions. Web Store makes install one-click.

**Effort:** S
**Priority:** P4
**Depends on:** Chrome extension proving value via sideloading

### Linux cookie decryption — PARTIALLY SHIPPED

~~**What:** GNOME Keyring / kwallet / DPAPI support for non-macOS cookie import.~~

Linux cookie import shipped in v0.11.11.0 (Wave 3). Supports Chrome, Chromium, Brave, Edge on Linux with GNOME Keyring (libsecret) and "peanuts" fallback. Windows DPAPI support remains deferred.

**Remaining:** Windows cookie decryption (DPAPI). Needs complete rewrite — PR #64 was 1346 lines and stale.

**Effort:** L (Windows only)
**Priority:** P4
**Completed (Linux):** v0.11.11.0 (2026-03-23)

## Ship

### GitLab support for /land-and-deploy

**What:** Add GitLab MR merge + CI polling support to `/land-and-deploy` skill. Currently uses `gh pr view`, `gh pr checks`, `gh pr merge`, and `gh run list/view` in 15+ places — each needs a GitLab conditional path using `glab ci status`, `glab mr merge`, etc.

**Why:** Without this, GitLab users can `/ship` (create MR) but can't `/land-and-deploy` (merge + verify). Completes the GitLab story end-to-end.

**Context:** `/retro`, `/ship`, and `/document-release` now support GitLab via the multi-platform `BASE_BRANCH_DETECT` resolver. `/land-and-deploy` has deeper GitHub-specific semantics (merge queues, required checks via `gh pr checks`, deploy workflow polling) that have different shapes on GitLab. The `glab` CLI (v1.90.0) supports `glab mr merge`, `glab ci status`, `glab ci view` but with different output formats and no merge queue concept.

**Effort:** L
**Priority:** P2
**Depends on:** None (BASE_BRANCH_DETECT multi-platform resolver is already done)

### Ship log — persistent record of /ship runs

**What:** Append structured JSON entry to `.gstack/ship-log.json` at end of every /ship run (version, date, branch, PR URL, review findings, Greptile stats, todos completed, test results).

**Why:** /retro has no structured data about shipping velocity. Ship log enables: PRs-per-week trending, review finding rates, Greptile signal over time, test suite growth.

**Context:** /retro already reads greptile-history.md — same pattern. Eval persistence (eval-store.ts) shows the JSON append pattern exists in the codebase. ~15 lines in ship template.

**Effort:** S
**Priority:** P2
**Depends on:** None


### Visual verification with screenshots in PR body

**What:** /ship Step 7.5: screenshot key pages after push, embed in PR body.

**Why:** Visual evidence in PRs. Reviewers see what changed without deploying locally.

**Context:** Part of Phase 3.6. Needs S3 upload for image hosting.

**Effort:** M
**Priority:** P2
**Depends on:** /setup-gstack-upload

## Review

### Inline PR annotations

**What:** /ship and /review post inline review comments at specific file:line locations using `gh api` to create pull request review comments.

**Why:** Line-level annotations are more actionable than top-level comments. The PR thread becomes a line-by-line conversation between Greptile, Claude, and human reviewers.

**Context:** GitHub supports inline review comments via `gh api repos/$REPO/pulls/$PR/reviews`. Pairs naturally with Phase 3.6 visual annotations.

**Effort:** S
**Priority:** P2
**Depends on:** None

### Greptile training feedback export

**What:** Aggregate greptile-history.md into machine-readable JSON summary of false positive patterns, exportable to the Greptile team for model improvement.

**Why:** Closes the feedback loop — Greptile can use FP data to stop making the same mistakes on your codebase.

**Context:** Was a P3 Future Idea. Upgraded to P2 now that greptile-history.md data infrastructure exists. The signal data is already being collected; this just makes it exportable. ~40 lines.

**Effort:** S
**Priority:** P2
**Depends on:** Enough FP data accumulated (10+ entries)

### Visual review with annotated screenshots

**What:** /review Step 4.5: browse PR's preview deploy, annotated screenshots of changed pages, compare against production, check responsive layouts, verify accessibility tree.

**Why:** Visual diff catches layout regressions that code review misses.

**Context:** Part of Phase 3.6. Needs S3 upload for image hosting.

**Effort:** M
**Priority:** P2
**Depends on:** /setup-gstack-upload

## QA

### QA trend tracking

**What:** Compare baseline.json over time, detect regressions across QA runs.

**Why:** Spot quality trends — is the app getting better or worse?

**Context:** QA already writes structured reports. This adds cross-run comparison.

**Effort:** S
**Priority:** P2

### CI/CD QA integration

**What:** `/qa` as GitHub Action step, fail PR if health score drops.

**Why:** Automated quality gate in CI. Catch regressions before merge.

**Effort:** M
**Priority:** P2

### Smart default QA tier

**What:** After a few runs, check index.md for user's usual tier pick, skip the AskUserQuestion.

**Why:** Reduces friction for repeat users.

**Effort:** S
**Priority:** P2

### Accessibility audit mode

**What:** `--a11y` flag for focused accessibility testing.

**Why:** Dedicated accessibility testing beyond the general QA checklist.

**Effort:** S
**Priority:** P3

### CI/CD generation for non-GitHub providers

**What:** Extend CI/CD bootstrap to generate GitLab CI (`.gitlab-ci.yml`), CircleCI (`.circleci/config.yml`), and Bitrise pipelines.

**Why:** Not all projects use GitHub Actions. Universal CI/CD bootstrap would make test bootstrap work for everyone.

**Context:** v1 ships with GitHub Actions only. Detection logic already checks for `.gitlab-ci.yml`, `.circleci/`, `bitrise.yml` and skips with an informational note. Each provider needs ~20 lines of template text in `generateTestBootstrap()`.

**Effort:** M
**Priority:** P3
**Depends on:** Test bootstrap (shipped)

### Auto-upgrade weak tests (★) to strong tests (★★★)

**What:** When Step 3.4 coverage audit identifies existing ★-rated tests (smoke/trivial assertions), generate improved versions testing edge cases and error paths.

**Why:** Many codebases have tests that technically exist but don't catch real bugs — `expect(component).toBeDefined()` isn't testing behavior. Upgrading these closes the gap between "has tests" and "has good tests."

**Context:** Requires the quality scoring rubric from the test coverage audit. Modifying existing test files is riskier than creating new ones — needs careful diffing to ensure the upgraded test still passes. Consider creating a companion test file rather than modifying the original.

**Effort:** M
**Priority:** P3
**Depends on:** Test quality scoring (shipped)

## Retro

### Deployment health tracking (retro + browse)

**What:** Screenshot production state, check perf metrics (page load times), count console errors across key pages, track trends over retro window.

**Why:** Retro should include production health alongside code metrics.

**Context:** Requires browse integration. Screenshots + metrics fed into retro output.

**Effort:** L
**Priority:** P3
**Depends on:** Browse sessions

## Infrastructure

### /setup-gstack-upload skill (S3 bucket)

**What:** Configure S3 bucket for image hosting. One-time setup for visual PR annotations.

**Why:** Prerequisite for visual PR annotations in /ship and /review.

**Effort:** M
**Priority:** P2

### gstack-upload helper

**What:** `browse/bin/gstack-upload` — upload file to S3, return public URL.

**Why:** Shared utility for all skills that need to embed images in PRs.

**Effort:** S
**Priority:** P2
**Depends on:** /setup-gstack-upload

### WebM to GIF conversion

**What:** ffmpeg-based WebM → GIF conversion for video evidence in PRs.

**Why:** GitHub PR bodies render GIFs but not WebM. Needed for video recording evidence.

**Effort:** S
**Priority:** P3
**Depends on:** Video recording



### Extend worktree isolation to Claude E2E tests

**What:** Add `useWorktree?: boolean` option to `runSkillTest()` so any Claude E2E test can opt into worktree mode for full repo context instead of tmpdir fixtures.

**Why:** Some Claude E2E tests (CSO audit, review-sql-injection) create minimal fake repos but would produce more realistic results with full repo context. The infrastructure exists (`describeWithWorktree()` in e2e-helpers.ts) — this extends it to the session-runner level.

**Context:** WorktreeManager shipped in v0.11.12.0. Currently only Gemini/Codex tests use worktrees. Claude tests use planted-bug fixture repos which are correct for their purpose, but new tests that want real repo context can use `describeWithWorktree()` today. This TODO is about making it even easier via a flag on `runSkillTest()`.

**Effort:** M (human: ~2 days / CC: ~20 min)
**Priority:** P3
**Depends on:** Worktree isolation (shipped v0.11.12.0)

### E2E model pinning — SHIPPED

~~**What:** Pin E2E tests to claude-sonnet-4-6 for cost efficiency, add retry:2 for flaky LLM responses.~~

Shipped: Default model changed to Sonnet for structure tests (~30), Opus retained for quality tests (~10). `--retry 2` added. `EVALS_MODEL` env var for override. `test:e2e:fast` tier added. Rate-limit telemetry (first_response_ms, max_inter_turn_ms) and wall_clock_ms tracking added to eval-store.

### Eval web dashboard

**What:** `bun run eval:dashboard` serves local HTML with charts: cost trending, detection rate, pass/fail history.

**Why:** Visual charts better for spotting trends than CLI tools.

**Context:** Reads `~/.gstack-dev/evals/*.json`. ~200 lines HTML + chart.js via Bun HTTP server.

**Effort:** M
**Priority:** P3
**Depends on:** Eval persistence (shipped in v0.3.6)

### CI/CD QA quality gate

**What:** Run `/qa` as a GitHub Action step, fail PR if health score drops below threshold.

**Why:** Automated quality gate catches regressions before merge. Currently QA is manual — CI integration makes it part of the standard workflow.

**Context:** Requires headless browse binary available in CI. The `/qa` skill already produces `baseline.json` with health scores — CI step would compare against the main branch baseline and fail if score drops. Would need `ANTHROPIC_API_KEY` in CI secrets since `/qa` uses Claude.

**Effort:** M
**Priority:** P2
**Depends on:** None

### Cross-platform URL open helper

**What:** `gstack-open-url` helper script — detect platform, use `open` (macOS) or `xdg-open` (Linux).

**Why:** The first-time Completeness Principle intro uses macOS `open` to launch the essay. If gstack ever supports Linux, this silently fails.

**Effort:** S (human: ~30 min / CC: ~2 min)
**Priority:** P4
**Depends on:** Nothing

### CDP-based DOM mutation detection for ref staleness

**What:** Use Chrome DevTools Protocol `DOM.documentUpdated` / MutationObserver events to proactively invalidate stale refs when the DOM changes, without requiring an explicit `snapshot` call.

**Why:** Current ref staleness detection (async count() check) only catches stale refs at action time. CDP mutation detection would proactively warn when refs become stale, preventing the 5-second timeout entirely for SPA re-renders.

**Context:** Parts 1+2 of ref staleness fix (RefEntry metadata + eager validation via count()) are shipped. This is Part 3 — the most ambitious piece. Requires CDP session alongside Playwright, MutationObserver bridge, and careful performance tuning to avoid overhead on every DOM change.

**Effort:** L
**Priority:** P3
**Depends on:** Ref staleness Parts 1+2 (shipped)

## Office Hours / Design

### Design docs → Supabase team store sync

**What:** Add design docs (`*-design-*.md`) to the Supabase sync pipeline alongside test plans, retro snapshots, and QA reports.

**Why:** Cross-team design discovery at scale. Local `~/.gstack/projects/$SLUG/` keyword-grep discovery works for same-machine users now, but Supabase sync makes it work across the whole team. Duplicate ideas surface, everyone sees what's been explored.

**Context:** /office-hours writes design docs to `~/.gstack/projects/$SLUG/`. The team store already syncs test plans, retro snapshots, QA reports. Design docs follow the same pattern — just add a sync adapter.

**Effort:** S
**Priority:** P2
**Depends on:** `garrytan/team-supabase-store` branch landing on main

### /yc-prep skill

**What:** Skill that helps founders prepare their YC application after /office-hours identifies strong signal. Pulls from the design doc, structures answers to YC app questions, runs a mock interview.

**Why:** Closes the loop. /office-hours identifies the founder, /yc-prep helps them apply well. The design doc already contains most of the raw material for a YC application.

**Effort:** M (human: ~2 weeks / CC: ~2 hours)
**Priority:** P2
**Depends on:** office-hours founder discovery engine shipping first

## Design Review

### /plan-design-review + /qa-design-review + /design-consultation — SHIPPED

Shipped as v0.5.0 on main. Includes `/plan-design-review` (report-only design audit), `/qa-design-review` (audit + fix loop), and `/design-consultation` (interactive DESIGN.md creation). `{{DESIGN_METHODOLOGY}}` resolver provides shared 80-item design audit checklist.

### Design outside voices in /plan-eng-review

**What:** Extend the parallel dual-voice pattern (Codex + Claude subagent) to /plan-eng-review's architecture review section.

**Why:** The design beachhead (v0.11.3.0) proves cross-model consensus works for subjective reviews. Architecture reviews have similar subjectivity in tradeoff decisions.

**Context:** Depends on learnings from the design beachhead. If the litmus scorecard format proves useful, adapt it for architecture dimensions (coupling, scaling, reversibility).

**Effort:** S
**Priority:** P3
**Depends on:** Design outside voices shipped (v0.11.3.0)

### Outside voices in /qa visual regression detection

**What:** Add Codex design voice to /qa for detecting visual regressions during bug-fix verification.

**Why:** When fixing bugs, the fix can introduce visual regressions that code-level checks miss. Codex could flag "the fix broke the responsive layout" during re-test.

**Context:** Depends on /qa having design awareness. Currently /qa focuses on functional testing.

**Effort:** M
**Priority:** P3
**Depends on:** Design outside voices shipped (v0.11.3.0)

## Document-Release

### Auto-invoke /document-release from /ship — SHIPPED

Shipped in v0.8.3. Step 8.5 added to `/ship` — after creating the PR, `/ship` automatically reads `document-release/SKILL.md` and executes the doc update workflow. Zero-friction doc updates.

### `{{DOC_VOICE}}` shared resolver

**What:** Create a placeholder resolver in gen-skill-docs.ts encoding the gstack voice guide (friendly, user-forward, lead with benefits). Inject into /ship Step 5, /document-release Step 5, and reference from CLAUDE.md.

**Why:** DRY — voice rules currently live inline in 3 places (CLAUDE.md CHANGELOG style section, /ship Step 5, /document-release Step 5). When the voice evolves, all three drift.

**Context:** Same pattern as `{{QA_METHODOLOGY}}` — shared block injected into multiple templates to prevent drift. ~20 lines in gen-skill-docs.ts.

**Effort:** S
**Priority:** P2
**Depends on:** None

## Ship Confidence Dashboard

### Smart review relevance detection — PARTIALLY SHIPPED

~~**What:** Auto-detect which of the 4 reviews are relevant based on branch changes (skip Design Review if no CSS/view changes, skip Code Review if plan-only).~~

`bin/gstack-diff-scope` shipped — categorizes diff into SCOPE_FRONTEND, SCOPE_BACKEND, SCOPE_PROMPTS, SCOPE_TESTS, SCOPE_DOCS, SCOPE_CONFIG. Used by design-review-lite to skip when no frontend files changed. Dashboard integration for conditional row display is a follow-up.

**Remaining:** Dashboard conditional row display (hide "Design Review: NOT YET RUN" when SCOPE_FRONTEND=false). Extend to Eng Review (skip for docs-only) and CEO Review (skip for config-only).

**Effort:** S
**Priority:** P3
**Depends on:** gstack-diff-scope (shipped)


## Codex

### Codex→Claude reverse buddy check skill

**What:** A Codex-native skill (`.agents/skills/gstack-claude/SKILL.md`) that runs `claude -p` to get an independent second opinion from Claude — the reverse of what `/codex` does today from Claude Code.

**Why:** Codex users deserve the same cross-model challenge that Claude users get via `/codex`. Currently the flow is one-way (Claude→Codex). Codex users have no way to get a Claude second opinion.

**Context:** The `/codex` skill template (`codex/SKILL.md.tmpl`) shows the pattern — it wraps `codex exec` with JSONL parsing, timeout handling, and structured output. The reverse skill would wrap `claude -p` with similar infrastructure. Would be generated into `.agents/skills/gstack-claude/` by `gen-skill-docs --host codex`.

**Effort:** M (human: ~2 weeks / CC: ~30 min)
**Priority:** P1
**Depends on:** None

## Completeness

### Completeness metrics dashboard

**What:** Track how often Claude chooses the complete option vs shortcut across gstack sessions. Aggregate into a dashboard showing completeness trend over time.

**Why:** Without measurement, we can't know if the Completeness Principle is working. Could surface patterns (e.g., certain skills still bias toward shortcuts).

**Context:** Would require logging choices (e.g., append to a JSONL file when AskUserQuestion resolves), parsing them, and displaying trends. Similar pattern to eval persistence.

**Effort:** M (human) / S (CC)
**Priority:** P3
**Depends on:** Boil the Lake shipped (v0.6.1)

## Safety & Observability

### On-demand hook skills (/careful, /freeze, /guard) — SHIPPED

~~**What:** Three new skills that use Claude Code's session-scoped PreToolUse hooks to add safety guardrails on demand.~~

Shipped as `/careful`, `/freeze`, `/guard`, and `/unfreeze` in v0.6.5. Includes hook fire-rate telemetry (pattern name only, no command content) and inline skill activation telemetry.

### Skill usage telemetry — SHIPPED

~~**What:** Track which skills get invoked, how often, from which repo.~~

Shipped in v0.6.5. TemplateContext in gen-skill-docs.ts bakes skill name into preamble telemetry line. Analytics CLI (`bun run analytics`) for querying. /retro integration shows skills-used-this-week.

### /investigate scoped debugging enhancements (gated on telemetry)

**What:** Six enhancements to /investigate auto-freeze, contingent on telemetry showing the freeze hook actually fires in real debugging sessions.

**Why:** /investigate v0.7.1 auto-freezes edits to the module being debugged. If telemetry shows the hook fires often, these enhancements make the experience smarter. If it never fires, the problem wasn't real and these aren't worth building.

**Context:** All items are prose additions to `investigate/SKILL.md.tmpl`. No new scripts.

**Items:**
1. Stack trace auto-detection for freeze directory (parse deepest app frame)
2. Freeze boundary widening (ask to widen instead of hard-block when hitting boundary)
3. Post-fix auto-unfreeze + full test suite run
4. Debug instrumentation cleanup (tag with DEBUG-TEMP, remove before commit)
5. Debug session persistence (~/.gstack/investigate-sessions/ — save investigation for reuse)
6. Investigation timeline in debug report (hypothesis log with timing)

**Effort:** M (all 6 combined)
**Priority:** P3
**Depends on:** Telemetry data showing freeze hook fires in real /investigate sessions
