+## [0.25.1] - 2026-05-01
+
+## **Your brain can now read books with you. Nine new skills land at once.**
+## **Plus: skillpack gets a real uninstall, the privacy guard learns new patterns.**
+
+`gbrain book-mirror` is the flagship. Hand it a book and a slug, and the agent fans out one read-only Opus subagent per chapter, assembles a personalized two-column analysis (left column preserves the chapter's actual content with stories and frameworks intact, right column maps every idea to your actual life using your words from the brain), and writes it as one operator-trust `put_page` to `media/books/<slug>-personalized.md`. Twenty-chapter book runs ~$6 at Opus. Subagents have read-only `allowed_tools: ['get_page', 'search']`, so untrusted EPUB content cannot prompt-inject any people page. The CLI prints a cost estimate and refuses to spend in non-TTY without `--yes`.
+
+Eight more skills ship alongside book-mirror: `article-enrichment` turns raw article dumps into structured pages with verbatim quotes; `strategic-reading` reads a book through one specific problem-lens with a do/avoid/watch-for playbook; `concept-synthesis` deduplicates thousands of concept stubs into a tiered intellectual map (T1 Canon to T4 Riff); `perplexity-research` does brain-augmented web research that focuses on the delta between what the brain knows and what's online now; `archive-crawler` mines personal file archives for high-value content within an explicit `gbrain.yml` allow-list; `academic-verify` traces a research claim through publication to raw data to replication; `brain-pdf` renders any brain page to publication-quality PDF; `voice-note-ingest` captures audio with exact-phrasing preservation and routes it to the right brain directory.
+
+`gbrain skillpack uninstall <name>` lands as a real CLI subcommand. Inverse of install, symmetric data-loss posture. Refuses if the slug isn't in the managed block's cumulative-slugs receipt (so it won't nuke a row you hand-added). Refuses if any installed file diverges from the bundle (you've edited it locally). `--overwrite-local` is the escape hatch, same as install. Atomic refusal — if any file would be blocked, the whole uninstall refuses before any unlink fires. No half-uninstalled state.
+
+Three existing skills got drift-backports from the maintainer's private fork: `citation-fixer` resolves broken tweet/post references to deterministic `x.com/handle/status/id` URLs via X API; `testing` splits into skill conformance + project test-suite health with regression-aware classification (REGRESSION / STALE / FLAKE / NEW / INFRA); `cross-modal-review` adds explicit gating ("when to invoke" vs "do NOT invoke") and a `/codex review` handoff for diff review.
+
+The privacy CI guard now also blocks `/data/brain/` and `/data/.openclaw/` literals. Seven historical files are allow-listed (frozen migration files, test fixtures, env-var fallback defaults).
+
+### The numbers that matter
+
+Counted against this branch's diff vs master and against the local test suite at the v0.25.1 cut:
+
+| Metric | BEFORE v0.25.1 | AFTER v0.25.1 | Δ |
+|---|---|---|---|
+| Skills shipped in `openclaw.plugin.json` | 25 | 34 | +9 |
+| New CLI commands | (existing) | `gbrain book-mirror`, `gbrain skillpack uninstall` | +2 |
+| Skills with drift-backport from upstream | 0 | 3 (citation-fixer, testing, cross-modal-review) | +3 |
+| Privacy CI guard banned-pattern coverage | 1 (fork-name literal) | 3 (+ `/data/brain/`, `/data/.openclaw/`) | +2 |
+| `gbrain skillpack` subcommands | 4 (list, install, diff, check) | 5 (+ uninstall) | +1 |
+| Skill-routing trust regression detector | 0 | media-ingest ↔ book-mirror routing-eval adversarial intents | +1 |
+| Filing-rule directories sanctioned | 12 | 16 (+ ideas, research, original, voice-note) | +4 |
+| Atomic-refusal contract on installer rollback | implicit (buggy on uninstall) | tested + enforced (`test/skillpack-uninstall.test.ts`) | locked |
+| Lines of new TypeScript src/ shipped | 0 | ~1,100 (book-mirror.ts + skillpack uninstall + archive-crawler-config + harness) | +1100 |
+| Tests added (unit + harness self-test) | (existing) | 62 (book-mirror, skillpack-uninstall, archive-crawler-config, cli-pty-runner) | +62 |
+
+Cross-model review trail: **Eng Review (R1 + R2)** + **Codex outside voice** with 15 user decisions captured (D1–D15), 0 unresolved. Codex caught the four highest-impact architectural mistakes the eng review missed: book-mirror's earlier `allowedSlugPrefixes: ['media/books/*', 'people/*']` design was a security regression; the fan-out runtime was missing infrastructure rather than the plan's assumed primitive; uninstall's content-hash guard was incomplete on user-modified files; archive-crawler's "trust the prompt" was not a control. All four were addressed before code landed.
+
+### What this means for builders
+
+Existing brains: no schema migration. `gbrain upgrade` does it.
+
+The flagship: `gbrain book-mirror --chapters-dir <path> --slug <slug>` once you've extracted the chapters (the skill walks you through EPUB and PDF extraction via BeautifulSoup4 / `pdftotext -layout`). The CLI is the trusted runtime; the skill is the orchestration prose.
+
+`gbrain skillpack uninstall <name>` if you ever want to remove a skill from your workspace. It refuses to do anything that would lose your edits.
+
+`archive-crawler` requires `archive-crawler.scan_paths:` set in `gbrain.yml` before it'll run. That's deliberate. Three-line allow-list, one-time pain, never wakes up at 3am wondering if the agent ingested your tax PDFs.
+
+The 9 new skills are all available immediately after `gbrain skillpack install <name>` (or `install --all`).
+
+## To take advantage of v0.25.1
+
+`gbrain upgrade` does this automatically. To verify:
+
+1. **Binary version:**
+   ```bash
+   gbrain --version   # expect: gbrain 0.25.1
+   ```
+2. **Book-mirror is registered:**
+   ```bash
+   gbrain book-mirror --help 2>&1 | grep "media/books/"
+   # expect: lines describing the trust contract
+   ```
+   (The CLI requires DB connection even for `--help` due to a pre-existing dispatch order; if you see "Cannot connect to database" your install is fine, the help text just needs DATABASE_URL set or a local PGLite brain.)
+3. **Skillpack uninstall is wired:**
+   ```bash
+   gbrain skillpack uninstall --help 2>&1 | grep "Inverse of install"
+   ```
+4. **Archive-crawler safety gate (only matters if you install it):**
+   ```bash
+   # Without gbrain.yml allow-list, the skill instructs the agent to refuse:
+   cat skills/archive-crawler/SKILL.md | grep "scan_paths"
+   ```
+5. **If anything fails,** file an issue at https://github.com/garrytan/gbrain/issues with the output of `gbrain doctor` and which step broke.
+
+No schema migration. Existing brains work unchanged.
+
+### Itemized changes
+
+#### Added (skills)
+
+- **`skills/book-mirror/`** — flagship. Two-column personalized chapter-by-chapter book analysis. SKILL.md ports the upstream original to pure gbrain idiom; CLI lives at `src/commands/book-mirror.ts`.
+- **`skills/article-enrichment/`** — transforms raw article dumps into structured pages with verbatim quotes, key insights, why-it-matters.
+- **`skills/strategic-reading/`** — reads a book / article / case study through one specific problem-lens; produces a do / avoid / watch-for playbook with short / medium / long-term recommendations.
+- **`skills/concept-synthesis/`** — 4-phase pipeline (dedup → tier → synthesize T1/T2 → cluster) over raw concept stubs; output is a curated intellectual fingerprint at `concepts/README.md`.
+- **`skills/perplexity-research/`** — sends brain context as part of the Perplexity prompt so the search focuses on what's NEW vs already-known. Output structure: Executive Summary + Key New Developments + Confirming Signals + Contradictions or Updates + Recommended Brain Updates + Citations.
+- **`skills/archive-crawler/`** — universal archivist for personal file archives (Dropbox / B2 / Gmail-takeout / local-mount / hard-drive-dump). REFUSES to run unless `archive-crawler.scan_paths:` is set in `gbrain.yml`.
+- **`skills/academic-verify/`** — verifies a research claim by tracing it through publication → methodology → raw data → independent replication. Routes through perplexity-research as the actual web-search engine; produces a verdict-shaped brain page (verified / partial / unverifiable / misattributed / retracted).
+- **`skills/brain-pdf/`** — generates publication-quality PDFs from any brain page via the gstack `make-pdf` binary. Strips frontmatter, sanitizes emoji, applies running headers + page numbers.
+- **`skills/voice-note-ingest/`** — ingests voice notes with exact-phrasing preservation (never paraphrased). 7-step decision tree routes to originals / concepts / people / companies / ideas / personal / voice-notes.
+
+#### Added (post-install advisory — v0.25.1 DX)
+
+- **`src/core/skillpack/post-install-advisory.ts`** (~209 lines). Every `gbrain init` and `gbrain post-upgrade` now ends by printing an agent-readable advisory listing the v0.25.1 recommended skills the workspace hasn't installed yet. The advisory tells the agent EXPLICITLY: ask the user before installing; print the exact `gbrain skillpack install --all` (or per-skill) command if they say yes. Renders to stderr so stdout stays clean for `--json` output. No-op when every recommended skill is already installed (no nag on repeated `gbrain upgrade` runs). Tests: `test/post-install-advisory.test.ts` (10 cases).
+  - Why this design instead of an interactive TTY prompt: gbrain users typically interact through their host agent, not the gbrain CLI directly. The agent reads command output. So the advisory is structured for agent consumption: `ACTION FOR THE AGENT` block, explicit `Ask the user explicitly`, exact commands, `Do NOT install without asking. The user owns this decision.`
+  - Wired into both `src/commands/init.ts` (PGLite + Postgres paths) and `src/commands/upgrade.ts` (`runPostUpgrade` after migrations apply).
+
+#### Added (CLI)
+
+- **`gbrain book-mirror`** — `src/commands/book-mirror.ts` (~540 lines). CLI submits N read-only subagent jobs per chapter, waits via `waitForCompletion`, reads each child's `job.result`, assembles markdown itself, writes one operator-trust `put_page` to `media/books/<slug>-personalized.md`. Cost-estimate prompt before launching; refuses to spend in non-TTY without `--yes`. Idempotency keys per chapter for retry-friendly re-runs. Partial-failure handling assembles the page with completed chapters and a `## Failed chapters` section listing retries needed.
+- **`gbrain skillpack uninstall <name>`** — `src/commands/skillpack.ts` + `src/core/skillpack/installer.ts:applyUninstall` (~250 lines). Symmetric to install. Atomic refusal: pre-scans all files for divergence; refuses BEFORE any unlink if anything is blocked. `--overwrite-local` escape hatch. Drops the slug from `cumulative-slugs` receipt; preserves other installed skills' rows + user-added unknown rows (with stderr warning).
+
+#### Added (filing-doctrine update)
+
+- **`skills/_brain-filing-rules.md`** — carved out `media/<format>/<slug>` as a sanctioned exception for sui-generis synthesized output (one-of-one to a single source like a personalized book mirror). The "file by primary subject, not by format" rule still applies to raw ingest.
+- **`skills/_brain-filing-rules.json`** — added 4 new directory kinds: `idea` (ideas/), `research` (research/), `original` (originals/), `voice-note` (voice-notes/). Plus 2 synthesis-output kinds for `media/books/` and `media/articles/`.
+- **`skills/media-ingest/SKILL.md`** — refined the format-based-filing anti-pattern callout to clarify that the anti-pattern is for raw ingest only; one-of-one synthesis output may use `media/<format>/`.
+
+#### Added (test infrastructure)
+
+- **`test/helpers/cli-pty-runner.ts`** — generic PTY harness ported from gstack (~470 lines). Used by the smoke test E2E; future-proofs interactive CLI commands.
+- **`test/cli-pty-runner.test.ts`** — 24 cases pinning the harness primitives.
+
+#### Added (CI guard)
+
+- **`scripts/check-privacy.sh`** extended with `BANNED_PATHS` for `/data/brain/` and `/data/.openclaw/`. 7 historical files allow-listed.
+
+#### Added (config schema)
+
+- **`src/core/archive-crawler-config.ts`** (~263 lines) + **`test/archive-crawler-config.test.ts`** (19 tests). `loadArchiveCrawlerConfig`, `normalizeAndValidateArchiveCrawlerConfig`, `isPathAllowed`. Mirrors the storage-config.ts parsing pattern.
+
+#### Drift backports (3 existing skills updated)
+
+- **`skills/citation-fixer/SKILL.md`** (1.0 → 1.1) — adds tweet/post URL resolution via X API. 5-step pipeline.
+- **`skills/testing/SKILL.md`** (1.0 → 1.1) — splits into skill conformance + project test-suite health with regression-aware classification.
+- **`skills/cross-modal-review/SKILL.md`** (1.0 → 1.1) — adds "When to invoke" gating and `/codex review` handoff.
+
+#### Bug fix (during testing)
+
+- **`applyUninstall` atomic refusal** — discovered while writing `test/skillpack-uninstall.test.ts`. The original implementation interleaved D11 hash check + unlink in the same loop, so a divergence on file 5/N would leave files 1..4 already gone. Now: pre-scan all files for divergence; refuse loudly BEFORE any filesystem mutation. The test was written with the contract in mind; the implementation lied about the contract; the lie surfaced immediately.
+
+#### Tests
+
+- **`test/book-mirror.test.ts`** — 9 cases.
+- **`test/skillpack-uninstall.test.ts`** — 10 cases.
+- **`test/archive-crawler-config.test.ts`** — 19 cases.
+- **`test/cli-pty-runner.test.ts`** — 24 cases.
+- 62 new tests total. All pass; existing 90+ skillpack-related tests continue to pass.
+
+#### Deferred to v0.26+
+
+- **`test/e2e/skill-smoke-openclaw.test.ts`** — full interactive openclaw drive via the PTY harness, opt-in via `EVALS=1 EVALS_TIER=skills`. Scaffolded but not landed.
+- **`gbrain skillpack uninstall --all`** — current shape is single-arg; multi-skill uninstall via `install --all` from a pruned bundle still works as the canonical path.
+- **Empty-parent-dir pruning on uninstall** — current behavior leaves empty `skills/<slug>/` directories. Cosmetic; deferred.
+- **LLM tie-break layer for routing-eval** — the routing-miss warnings on the new skills are real; the structural layer doesn't substring-match natural-paraphrased intents. The `--llm` flag stays a placeholder per v0.24.0.
+
+### Cross-model review credit
+
+This release ran two rounds of `/plan-eng-review` plus `/codex` outside voice, capturing 15 user decisions. Codex caught the four most consequential architectural mistakes the eng review missed (read the plan file's GSTACK REVIEW REPORT for the full audit trail). The atomic-refusal bug in applyUninstall was caught by the test for the contract — the test was written with the contract in mind, the implementation lied about the contract, and the lie surfaced immediately. That's the cross-model loop working.

 - `src/core/resolver-filenames.ts` (v0.19) — central list of accepted routing filenames (`RESOLVER.md`, `AGENTS.md`). Shared by `findRepoRoot`, `check-resolvable`, and skillpack install so every code path walks the same fallback chain.
 - `src/commands/skillify.ts` + `src/core/skillify/{generator,templates}.ts` (v0.19) — `gbrain skillify scaffold <name>` creates all stubs for a new skill in one command: SKILL.md, script, tests, routing-eval.jsonl, resolver entry, filing-rules pointer. `gbrain skillify check <script>` runs the 10-step checklist (LLM evals, routing evals, check-resolvable gate, filing audit) against a candidate skill before it lands.
 - `src/commands/skillify-check.ts` (v0.19) — `gbrain skillpack-check` agent-readable health report. Exit 0/1/2 for CI pipeline gating; JSON for debugging. Wraps `check-resolvable --json`, `doctor --json`, and migration ledger into one payload so agents can decide whether a human action is required.
-- `src/commands/skillpack.ts` + `src/core/skillpack/{bundle,installer}.ts` (v0.19) — `gbrain skillpack install` drops gbrain's curated 25-skill bundle into a host workspace, managed-block style. Never clobbers local edits; tracks a skill manifest so subsequent `install --update` diffs cleanly. Bundle builder (`skillpack/bundle.ts`) packages the set from `skills/` into a versioned payload. **v0.24.0:** managed block embeds a `<!-- gbrain:skillpack:manifest cumulative-slugs="..." version="..." -->` receipt inside the fence. Per-skill installs accumulate via `union(prior_receipt, this_call)`; `install --all` is the only path that prunes (drops slugs no longer in the bundle). Rows inside the fence whose slug is in neither the new cumulative set nor the bundle survive as user-added with a stderr `[skillpack] unknown row in managed block: "<slug>" — Investigate: ...` warning. Pre-v0.24 fences upgrade silently on first install (extracted slugs become the prior cumulative set).
+- `src/commands/book-mirror.ts` (v0.25.1) — `gbrain book-mirror --chapters-dir <path> --slug <slug> [flags]`. Flagship of the v0.25.1 skills wave. Submits N read-only subagent jobs (one per chapter; `allowed_tools: ['get_page', 'search']`), waits for all via `waitForCompletion`, reads each child's `job.result`, assembles two-column markdown CLI-side, writes a single operator-trust `put_page` to `media/books/<slug>-personalized.md`. Codex HIGH-1 fix applied: trust narrowing happens at the tool-allowlist layer (subagents can't call put_page) instead of allowedSlugPrefixes — untrusted EPUB content cannot prompt-inject any people page. Cost-estimate prompt before launching; refuses to spend in non-TTY without `--yes`. Per-chapter idempotency keys (`book-mirror:<slug>:ch-<N>`) for retry-friendly re-runs. Partial-failure handling: assembles with completed chapters and a `## Failed chapters` section listing retries. Test surface: `test/book-mirror.test.ts` (9 cases — CLI registration + source invariants).
+- `src/commands/skillpack.ts` + `src/core/skillpack/{bundle,installer}.ts` (v0.19) — `gbrain skillpack install` drops gbrain's curated 25-skill bundle into a host workspace, managed-block style. Never clobbers local edits; tracks a skill manifest so subsequent `install --update` diffs cleanly. Bundle builder (`skillpack/bundle.ts`) packages the set from `skills/` into a versioned payload. **v0.24.0:** managed block embeds a `<!-- gbrain:skillpack:manifest cumulative-slugs="..." version="..." -->` receipt inside the fence.

Rows inside the fence whose slug is in neither the new cumulative set nor the bundle survive as user-added with a stderr `[skillpack] unknown row in managed block: "<slug>" — Investigate: ...` warning. Pre-v0.24 fences upgrade silently on first install (extracted slugs become the prior cumulative set). **v0.25.1:** `gbrain skillpack uninstall <name>` lands as a real CLI subcommand. Inverse of install with symmetric data-loss posture: D8 refuses if the slug isn't in the cumulative-slugs receipt (won't nuke a hand-added row); D11 content-hash guard refuses if any installed file diverges from the bundle (you've edited it locally) unless `--overwrite-local` is passed. `applyUninstall` enforces an atomic-refusal contract: pre-scans ALL files for divergence; refuses BEFORE any unlink fires if anything is blocked. The bug fix landed via `test/skillpack-uninstall.test.ts`'s D11 case — the test was written with the contract in mind, the original implementation interleaved hash-check + unlink, and the lie surfaced immediately.
+- `src/core/archive-crawler-config.ts` (v0.25.1) — D12 + codex HIGH-4 safety gate for the `archive-crawler` skill. Refuses to run unless `archive-crawler.scan_paths:` is explicitly set in the brain repo's `gbrain.yml`. Mirrors the storage-config.ts parsing pattern (sibling file; separate concern from storage tiering). `loadArchiveCrawlerConfig(repoPath)` throws `ArchiveCrawlerConfigError(missing_section | empty_scan_paths | invalid_path | parse_error)`. `normalizeAndValidateArchiveCrawlerConfig` rejects relative paths and `..` traversal; `~` is expanded; trailing-slash normalized for unambiguous prefix matching. `isPathAllowed(candidate, config)` is the runtime per-file gate (scan_paths prefix-match with directory-boundary correctness; deny_paths overrides). Tests in `test/archive-crawler-config.test.ts` (19 cases).
+- `test/helpers/cli-pty-runner.ts` (v0.25.1) — generic real-PTY harness ported from gstack and trimmed to ~470 lines. Uses pure `Bun.spawn({terminal:})` (Bun 1.3.10+; engines.bun pin in package.json). Generic primitives only — no plan-mode orchestrators. Exports: `launchPty`, `resolveBinary`, `stripAnsi`, `parseNumberedOptions`, `optionsSignature`, `isNumberedOptionListVisible`, `isTrustDialogVisible`. Self-tests in `test/cli-pty-runner.test.ts` (24 cases).
 - `src/core/skill-manifest.ts` (v0.19) — parser for `skill-manifest.json` records. Used by skillpack installer to detect drift between the shipped bundle and the user's local edits, so updates merge instead of overwriting.
 - `src/commands/routing-eval.ts` + `src/core/routing-eval.ts` (v0.19) — `gbrain routing-eval` catches user phrasings that route to the wrong skill. Reads `skills/<name>/routing-eval.jsonl` fixtures (`{intent, expected_skill, ambiguous_with?}`). Structural layer runs in `check-resolvable` by default (zero API cost). The `--llm` flag is accepted as a placeholder for a future LLM tie-break layer; in v0.24.0 it emits a stderr notice and runs structural only. False positives surface before users hit them.
 - `src/core/filing-audit.ts` + `skills/_brain-filing-rules.json` (v0.19) — Check 6 of `check-resolvable`. Parses new `writes_pages:` / `writes_to:` frontmatter on skills and audits their filing claims against the filing-rules JSON. Warning-only in v0.19, upgrades to error in v0.20.

 [Skill files are code.](https://x.com/garrytan/status/2042925773300908103) They're the most powerful way to get knowledge work done. A skill file is a fat markdown document that encodes an entire workflow: when to fire, what to check, how to chain with other skills, what quality bar to enforce. The agent reads the skill and executes it. Skills can also call deterministic TypeScript code bundled in GBrain (search, import, embed, sync) for the parts that shouldn't be left to LLM judgment.

 - `src/core/resolver-filenames.ts` (v0.19) — central list of accepted routing filenames (`RESOLVER.md`, `AGENTS.md`). Shared by `findRepoRoot`, `check-resolvable`, and skillpack install so every code path walks the same fallback chain.
 - `src/commands/skillify.ts` + `src/core/skillify/{generator,templates}.ts` (v0.19) — `gbrain skillify scaffold <name>` creates all stubs for a new skill in one command: SKILL.md, script, tests, routing-eval.jsonl, resolver entry, filing-rules pointer. `gbrain skillify check <script>` runs the 10-step checklist (LLM evals, routing evals, check-resolvable gate, filing audit) against a candidate skill before it lands.
 - `src/commands/skillify-check.ts` (v0.19) — `gbrain skillpack-check` agent-readable health report. Exit 0/1/2 for CI pipeline gating; JSON for debugging. Wraps `check-resolvable --json`, `doctor --json`, and migration ledger into one payload so agents can decide whether a human action is required.
-- `src/commands/skillpack.ts` + `src/core/skillpack/{bundle,installer}.ts` (v0.19) — `gbrain skillpack install` drops gbrain's curated 25-skill bundle into a host workspace, managed-block style. Never clobbers local edits; tracks a skill manifest so subsequent `install --update` diffs cleanly. Bundle builder (`skillpack/bundle.ts`) packages the set from `skills/` into a versioned payload. **v0.24.0:** managed block embeds a `<!-- gbrain:skillpack:manifest cumulative-slugs="..." version="..." -->` receipt inside the fence. Per-skill installs accumulate via `union(prior_receipt, this_call)`; `install --all` is the only path that prunes (drops slugs no longer in the bundle). Rows inside the fence whose slug is in neither the new cumulative set nor the bundle survive as user-added with a stderr `[skillpack] unknown row in managed block: "<slug>" — Investigate: ...` warning. Pre-v0.24 fences upgrade silently on first install (extracted slugs become the prior cumulative set).
+- `src/commands/book-mirror.ts` (v0.25.1) — `gbrain book-mirror --chapters-dir <path> --slug <slug> [flags]`. Flagship of the v0.25.1 skills wave. Submits N read-only subagent jobs (one per chapter; `allowed_tools: ['get_page', 'search']`), waits for all via `waitForCompletion`, reads each child's `job.result`, assembles two-column markdown CLI-side, writes a single operator-trust `put_page` to `media/books/<slug>-personalized.md`. Codex HIGH-1 fix applied: trust narrowing happens at the tool-allowlist layer (subagents can't call put_page) instead of allowedSlugPrefixes — untrusted EPUB content cannot prompt-inject any people page. Cost-estimate prompt before launching; refuses to spend in non-TTY without `--yes`. Per-chapter idempotency keys (`book-mirror:<slug>:ch-<N>`) for retry-friendly re-runs. Partial-failure handling: assembles with completed chapters and a `## Failed chapters` section listing retries. Test surface: `test/book-mirror.test.ts` (9 cases — CLI registration + source invariants).
+- `src/commands/skillpack.ts` + `src/core/skillpack/{bundle,installer}.ts` (v0.19) — `gbrain skillpack install` drops gbrain's curated 25-skill bundle into a host workspace, managed-block style. Never clobbers local edits; tracks a skill manifest so subsequent `install --update` diffs cleanly.

Rows inside the fence whose slug is in neither the new cumulative set nor the bundle survive as user-added with a stderr `[skillpack] unknown row in managed block: "<slug>" — Investigate: ...` warning. Pre-v0.24 fences upgrade silently on first install (extracted slugs become the prior cumulative set). **v0.25.1:** `gbrain skillpack uninstall <name>` lands as a real CLI subcommand. Inverse of install with symmetric data-loss posture: D8 refuses if the slug isn't in the cumulative-slugs receipt (won't nuke a hand-added row); D11 content-hash guard refuses if any installed file diverges from the bundle (you've edited it locally) unless `--overwrite-local` is passed. `applyUninstall` enforces an atomic-refusal contract: pre-scans ALL files for divergence; refuses BEFORE any unlink fires if anything is blocked. The bug fix landed via `test/skillpack-uninstall.test.ts`'s D11 case — the test was written with the contract in mind, the original implementation interleaved hash-check + unlink, and the lie surfaced immediately.
+- `src/core/archive-crawler-config.ts` (v0.25.1) — D12 + codex HIGH-4 safety gate for the `archive-crawler` skill. Refuses to run unless `archive-crawler.scan_paths:` is explicitly set in the brain repo's `gbrain.yml`. Mirrors the storage-config.ts parsing pattern (sibling file; separate concern from storage tiering). `loadArchiveCrawlerConfig(repoPath)` throws `ArchiveCrawlerConfigError(missing_section | empty_scan_paths | invalid_path | parse_error)`. `normalizeAndValidateArchiveCrawlerConfig` rejects relative paths and `..` traversal; `~` is expanded; trailing-slash normalized for unambiguous prefix matching. `isPathAllowed(candidate, config)` is the runtime per-file gate (scan_paths prefix-match with directory-boundary correctness; deny_paths overrides). Tests in `test/archive-crawler-config.test.ts` (19 cases).
+- `test/helpers/cli-pty-runner.ts` (v0.25.1) — generic real-PTY harness ported from gstack and trimmed to ~470 lines. Uses pure `Bun.spawn({terminal:})` (Bun 1.3.10+; engines.bun pin in package.json). Generic primitives only — no plan-mode orchestrators. Exports: `launchPty`, `resolveBinary`, `stripAnsi`, `parseNumberedOptions`, `optionsSignature`, `isNumberedOptionListVisible`, `isTrustDialogVisible`. Self-tests in `test/cli-pty-runner.test.ts` (24 cases).
 - `src/core/skill-manifest.ts` (v0.19) — parser for `skill-manifest.json` records. Used by skillpack installer to detect drift between the shipped bundle and the user's local edits, so updates merge instead of overwriting.
 - `src/commands/routing-eval.ts` + `src/core/routing-eval.ts` (v0.19) — `gbrain routing-eval` catches user phrasings that route to the wrong skill. Reads `skills/<name>/routing-eval.jsonl` fixtures (`{intent, expected_skill, ambiguous_with?}`). Structural layer runs in `check-resolvable` by default (zero API cost). The `--llm` flag is accepted as a placeholder for a future LLM tie-break layer; in v0.24.0 it emits a stderr notice and runs structural only. False positives surface before users hit them.
 - `src/core/filing-audit.ts` + `skills/_brain-filing-rules.json` (v0.19) — Check 6 of `check-resolvable`. Parses new `writes_pages:` / `writes_to:` frontmatter on skills and audits their filing claims against the filing-rules JSON. Warning-only in v0.19, upgrades to error in v0.20.

The resolver tells your agent which skill to read for any task. v0.25.1 added 9 research-flavored skills (`book-mirror` flagship plus 8 pairings); see the new "Research and synthesis" section below.
 
 [Skill files are code.](https://x.com/garrytan/status/2042925773300908103) They're the most powerful way to get knowledge work done. A skill file is a fat markdown document that encodes an entire workflow: when to fire, what to check, how to chain with other skills, what quality bar to enforce. The agent reads the skill and executes it. Skills can also call deterministic TypeScript code bundled in GBrain (search, import, embed, sync) for the parts that shouldn't be left to LLM judgment.

+## Sanctioned exception: synthesis output is sui generis
+
+The "file by primary subject" rule is for raw ingest. Synthesized output that
+is one-of-one to a single source AND a specific reader (a personalized book
+mirror, a strategic-reading playbook tied to one problem) does not fit any
+subject directory cleanly: filing by topic loses the "this is the book"
+dimension; filing by author muddles authorship pages with synthesis pages.
+
+Format-prefixed paths under `media/<format>/<slug>` are the sanctioned
+exception:
+
+- `media/books/<slug>-personalized.md` (book-mirror output)
+- `media/articles/<slug>-personalized.md` (long-form article personalization)
+
+If you find yourself wanting `media/<format>/` for raw ingest, that is still
+the anti-pattern in the table above. The exception is narrow: synthesized,
+one-of-one, sui generis to a single source.

+# academic-verify — Trace Claims to Source Data
+
+> **Convention:** see [conventions/quality.md](../conventions/quality.md) for
+> citation rules; every verdict cites the source data, not just the
+> author's claim about the source data.
+>
+> **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md)
+> for the lookup chain. This skill enforces brain-first by checking
+> existing brain pages before issuing a fresh web search.
+
+## What this is
+
+A claim-verification flow for academic / research statements. When a
+book, article, or speaker cites a study or quotes a number, this skill
+traces the claim through:
+
+```
+claim → publication → methodology section → raw data source → independent verification
+```
+
+At each step, it answers:
+
+- **Where does this number come from?** (Self-generated? Survey? Government data?)
+- **What's the baseline?** (Reduction from what? Over what time period?)
+- **Is the raw data available?** (Public? Proprietary? "Available on request"?)
+- **Has anyone independently verified it?** (Replication study? Government audit?)
+- **Are there confounding factors?** (Other interventions, policy changes, COVID, sampling bias?)
+- **Is the comparison fair?** (Cherry-picked comparison group? Survivorship bias?)
+
+The output is a brain page under `concepts/<claim-slug>.md` that records
+the claim, the trace, and the verdict — so future references to the
+same claim can re-use the verified analysis.
+
+## When to use this
+
+- A book quotes a study and you want to confirm it's real and not
+  miscited
+- An article makes a quantified claim ("X reduced Y by 40%") that you
+  want traced to the source data
+- You're writing something that depends on a piece of research and you
+  want to verify the underlying paper holds up
+- You're updating a brain page that cites a research claim and you want
+  to record the verification status alongside
+
+## What this skill is NOT
+
+- Not adversarial / oppo work. The point is rigor, not takedown.
+- Not generic web research — use `perplexity-research` directly for
+  open-ended topic exploration.
+- Not a brain-only lookup — that's `gbrain query`.
+
+## How it works (D7/α: pure routing through perplexity-research)
+
+academic-verify is a thin orchestrator. The actual web search is done
+by [perplexity-research](../perplexity-research/SKILL.md). academic-verify's
+job is the *workflow*: scoping the claim precisely, sending it through
+perplexity-research with citation-mode, then formatting the response
+into a verdict-shaped brain page.
+
+```
+Step 1: Scope the claim
+  Pin down EXACTLY what's being claimed:
+    • Quote: who said what?
+    • Source: which paper / dataset / survey?
+    • Number: what specific quantity is claimed?
+    • Period: over what time range?
+
+Step 2: Brain-first lookup
+  gbrain query "<paper title> OR <author name> OR <claim keywords>"
+  If the brain has prior verification of this claim, reuse it.
+
+Step 3: Invoke perplexity-research with citation-mode prompt
+  Send the claim + brain context to perplexity-research with a prompt
+  that explicitly asks for:
+    • Original publication (title, authors, journal, year, DOI)
+    • Methodology section summary
+    • Raw data availability (public repo? proprietary?)
+    • Independent replication status (Retraction Watch / PubPeer hits)
+    • Citations of the paper that critique or contextualize it
+
+Step 4: Format the verdict
+  Write the result to concepts/<claim-slug>.md. The verdict is one of:
+    • Verified — claim is accurate; raw data available; replication exists
+    • Partially verified — claim correct on the underlying paper but
+      methodology has known limits; record limits explicitly
+    • Unverifiable — no public data, no replication; not enough to act
+    • Misattributed — the claim cites a paper but the paper doesn't say that
+    • Retracted / disputed — paper has known retraction or
+      well-documented critique
+
+Step 5: Cross-link to original sources
+  Add the paper authors to people/ if they have brain pages, or create
+  one if notable. Iron Law per conventions/quality.md.
+```
+
+## Output: brain page format
+
+```markdown
+---
+title: "[Claim summary] — Verified"
+type: research
+date: YYYY-MM-DD
+verdict: "verified|partial|unverifiable|misattributed|retracted"
+brain_context_slugs: ["pages cited as context"]
+---
+
+# [Claim summary] — Verified
+
+> One-line: the verdict + the bottom-line reason.
+
+## The Claim
+
+> Exact quote, exactly as stated, with source attribution.
+
+## Trace
+
+| Step | Finding | Source |
+|------|---------|--------|
+| Original publication | [Title, authors, year, DOI] | [URL] |
+| Methodology | [1-line summary; flag obvious limits] | [URL] |
+| Raw data | [Public repo / proprietary / available-on-request] | [URL] |
+| Independent replication | [Replication studies and their results] | [URL] |
+| Critical citations | [Papers that critique this work] | [URL] |
+
+## Verdict
+
+[Verified / Partially verified / Unverifiable / Misattributed / Retracted]
+
+[1-2 paragraphs explaining WHY the verdict, with specific evidence.]
+
+## Caveats
+
+[Honest limits: what we couldn't verify, what would change the verdict.]
+
+## See Also
+
+- Original paper: [Title](DOI URL)
+- Authors' brain pages: [Author 1](people/author-1.md), ...
+- Related claims (verified or otherwise): [...]

+
+## Useful databases (the agent uses these via perplexity-research)
+
+| Database | What it has | URL pattern |
+|----------|-------------|-------------|
+| Retraction Watch | Retractions, corrections, expressions of concern | retractionwatch.com/?s=NAME |
+| PubPeer | Anonymous post-publication peer review | pubpeer.com/search?q=NAME |
+| OSF | Pre-registrations, open data, open materials | osf.io/search/?q=QUERY |
+| Semantic Scholar | Citation analysis, paper metadata | api.semanticscholar.org |
+| OpenAlex | Open citation data, institutional affiliations | api.openalex.org |
+| Many Labs | Replication results for social psychology | osf.io/wx7ck/ |
+
+## Standards (the rigor bar)
+
+- **Verified** — only when the underlying paper exists, raw data is
+  public OR an independent lab has confirmed the result, and the citing
+  source represents the claim accurately.
+- **Partial** — paper is real and findings stand, but the citation
+  context oversells (e.g., "X causes Y" when the paper shows
+  correlation, or "all studies find X" when it's one underpowered study).
+- **Unverifiable** — the underlying number can't be traced to source
+  data, no replication has been done, no independent confirmation
+  exists. Not the same as "wrong" — say "we couldn't verify."
+- **Misattributed** — the citation points to a paper, but the paper
+  doesn't actually say what the citation claims. Common in policy briefs.
+- **Retracted / disputed** — paper has been retracted, has a major
+  expression-of-concern, or has well-documented critique that
+  contradicts the headline finding.
+
+Never claim a problem without evidence. The verification document
+itself is the artifact — if the claim holds up, say so plainly. If it
+doesn't, the trace speaks for itself.
+
+## Anti-Patterns
+
+- ❌ Skipping the brain-first lookup. Re-doing verification we've
+  already done is wasted Perplexity spend.
+- ❌ Bypassing perplexity-research and inventing the lookup. The
+  citations from Perplexity are the evidence — without them, the
+  verdict is just opinion.
+- ❌ Stating "Verified" without confirming raw data availability.
+  Replication trumps any single paper.
+- ❌ Stating "Unverifiable" when you simply didn't look hard enough.
+  The verdict is on the source, not on your search effort.

+
+## Safety gate (REQUIRED, no exceptions)
+
+archive-crawler refuses to run unless `archive-crawler.scan_paths:` is
+explicitly set in `gbrain.yml`. This is a deliberate safety fence against
+the agent over-scoping a scan and ingesting sensitive content (tax PDFs,
+medical records, credentials).
+
+```yaml
+# gbrain.yml — the allow-list is mandatory
+archive-crawler:
+  scan_paths:
+    - ~/Documents/writing/
+    - ~/Dropbox/Archive/
+    - /mnt/backup/old-letters/
+  # Optional deny-list inside the allow-list:
+  # deny_paths:
+  #   - ~/Documents/finances/
+  #   - ~/Documents/medical/
+```
+
+If `scan_paths` is empty or missing, the skill exits with:
+
+```
+archive-crawler: refusing to run. No `archive-crawler.scan_paths:` allow-list
+in gbrain.yml. Add explicit paths the agent is permitted to scan, then re-run.
+This is a safety fence — the agent will not infer what's safe to read.
+```
+
+This contract is enforced by `src/core/storage-config.ts` (mirrors the
+`db_tracked` / `db_only` allow-list pattern from v0.22.11 storage tiering).
+
+## What this is
+
+Generic engine for exploring any tree of personal content within an
+explicit allow-list. Works on local mounts, Dropbox API targets,
+Backblaze B2, Gmail takeouts (`.mbox`), and similar archives. Filters
+for "gold" (the user's own writing, ideas, relationships) and surfaces
+it interactively for review. Skips noise (system files, configs, binary
+blobs).
+
+## Concepts
+
+### Source
+
+A source is any tree of files to explore. Sources have:
+
+- **type**: `local` | `dropbox` | `backblaze` | `gmail-takeout` | `mbox` | `pst`
+- **root**: filesystem path, Dropbox path, B2 prefix, mbox path
+- **manifest**: a brain page tracking progress at
+  `projects/<archive-slug>/STATUS.md`
+
+### Manifest
+
+Every archive exploration gets a manifest brain page that tracks:
+
+1. **Tree inventory** — folders / files / sizes / types
+2. **Triage status** — each item: `⬜ unseen` / `👀 reviewed` /
+   `✅ ingested` / `⏭️ skip` / `🔥 high-signal`
+3. **User reactions** — exact quotes when they react (per
+   conventions/quality.md exact-phrasing rule)
+4. **Priority queue** — what to explore next, ranked
+5. **Session log** — timestamped record of what was shown per session
+
+### Gold filter
+
+Before showing anything to the user, apply the gold filter:
+
+| Keep (show) | Skip (note existence, don't show) |
+|-------------|-----------------------------------|
+| Personal writing (journals, letters, reflections, essays) | System files, configs, package.json, node_modules |
+| Conversations (IM logs, email threads with substance) | Binary blobs (images / video) |
+| Ideas, theses, frameworks | Receipts, invoices, tax docs |
+| Relationship material (letters to / from people who matter) | Spam, newsletters, mailing-list bulk |
+| Creative work (poetry, stories, code with soul) | Corrupted / null files |
+| Origin stories (first versions of things that became important) | |
+| Emotional content (anger, love, grief, discovery) | |
+
+## Protocol
+
+### Phase 1: Inventory
+
+When pointed at a new source:
+
+1. **Confirm scan_paths is set** (safety gate). Exit if not.
+2. **Map the tree** — list folders + files + sizes + date ranges.
+3. **Classify folders** — group by likely content type (writing, email,
+   code, photos, docs, system).
+4. **Create manifest** — write `projects/<archive-slug>/STATUS.md` with
+   the full inventory.
+5. **Propose priority queue** — rank folders by likely gold density.
+6. **Present to user** — show the map and proposed order. Let them
+   override.
+
+### Phase 2: Crawl
+
+Work through folders in priority order:
+
+1. **Read before showing** — open each candidate file, apply the gold
+   filter, skip noise.
+2. **Show one at a time** — present gold items individually for review.
+3. **Capture exact reaction** — track the user's response in the
+   manifest using their exact words (per conventions/quality.md).
+4. **Ingest if worth keeping** — create a brain page immediately.
+5. **Update manifest** — mark item status after each interaction.
+6. **Never re-show** — check the manifest before presenting anything.
+
+### Phase 3: Ingest
+
+When an item is worth keeping, file it by **primary subject** per
+`_brain-filing-rules.md`:
+
+- User's own writing / ideas / origin-story content → `originals/<slug>.md`
+- Reflections / personal-life content → `personal/<slug>.md`
+- Product / business ideas → `ideas/<slug>.md`
+- Letters or threads about a specific person → `people/<person>/timeline`
+  back-link plus the letter at `personal/<slug>.md` or `originals/<slug>.md`
+
+**The skill is schema-generic.** It does NOT bake in any specific
+era-folder structure (e.g., `originals/archive/` for pre-2003,
+`originals/yc-era/` for post-2019, etc.). The user's filing rules from
+`_brain-filing-rules.json` are read at runtime; the agent decides per-page
+where content lands within those sanctioned directories.
+
+Brain page format:
+
+```markdown
+---
+title: "[Title or first line]"
+type: original
+source_type: "[local|dropbox|backblaze|gmail-takeout|mbox|pst]"
+source_path: "[path within the allow-listed scan_paths]"
+date: "YYYY-MM-DD"  # date from the file metadata or content
+people: ["person-1", "person-2"]
+tags: ["tag-1", "tag-2"]
+---
+
+# [Title]
+
+[Summary: what it is, when it's from, why it matters]
+
+**User's reaction:** [exact quote, no paraphrasing]
+

+- ❌ Hardcoding era-specific filing paths (e.g., `originals/archive/`,
+  `originals/yc-era/`). Read filing rules at runtime instead.
+- ❌ Re-showing items already marked in the manifest. The user's time
+  is the scarcest resource.
+- ❌ Paraphrasing reactions. Exact words only.
+- ❌ Wrapping found content in lessons or takeaways. Let stories breathe.
+- ❌ Skipping back-links when content references people / companies who
+  have brain pages. Iron Law per conventions/quality.md.

+- **Key Insights** — actual insights, not topic labels
+- **Surprising or Counterintuitive** — what makes this content unique
+- **See Also** — standard markdown links to related brain pages
+
+Raw source content is preserved in a collapsed `<details>` section so the
+original is never lost.
+
+## When to invoke
+
+- New article page lands in the brain via media-ingest with `needs_enrichment: true`
+- Existing article page is a wall of text under a `## Content` header with
+  no synthesis
+- User says a brain page is useless, boring, or a dump
+- An LLM-judge brain-quality eval fails on quotability or actionability for
+  an article page
+
+## The pipeline
+
+```
+1. READ      → Open the article brain page; parse frontmatter + body.
+2. SCAN      → Look for ## Content (raw dump) and absence of ## Executive Summary.
+3. CONTEXT   → gbrain query the article's key entities to ground "Why It Matters".
+4. ENRICH    → Sonnet (default) or Opus (for high-value content) restructures.
+5. WRITE     → Replace ## Content with the structured sections; preserve raw
+               source in <details>; clear needs_enrichment in frontmatter.
+6. CROSS-LINK→ Add back-links from referenced people/companies pages
+               (Iron Law per conventions/quality.md).
+```
+
+## Invocation
+
+The skill itself is markdown instructions to the agent. It does NOT ship a
+deterministic CLI command in v0.25.1. The agent uses gbrain's existing
+operations:
+
+```bash
+# 1. Find candidate pages
+gbrain query "needs_enrichment: true type:article" --limit 50
+
+# 2. For each candidate, read the page
+gbrain get media/articles/<slug>
+
+# 3. Enrich via the agent's LLM (Sonnet by default; Opus for high-value)
+#    The agent reads the raw content + brain context + writes the structured page.
+
+# 4. Write the enriched page
+#    Use the put_page operation with the new structured markdown body.
+
+# 5. Cross-link entities
+#    For every person/company mentioned, add a timeline back-link.
+```
+
+## Quality bar
+
+An enriched page passes if it has:
+
+- ✅ `## Executive Summary` (2-3 sentences)
+- ✅ `## Quotable Lines` with ≥3 verbatim quotes (literal quotes, not paraphrase)
+- ✅ `## Key Insights` with ≥3 bullets (insights, not topic labels)
+- ✅ `## Why It Matters` connecting to specific brain context (not generic)
+- ✅ `## See Also` with standard markdown links (NOT `[[wiki-links]]`)
+- ✅ `<details>` block preserving the raw source content
+
+## Model selection
+
+| Model | Use when | Quote accuracy |
+|-------|----------|----------------|
+| **Sonnet** (default) | Bulk enrichment, most articles | Good — occasionally paraphrases |
+| **Opus** | High-value content, original-thinking pieces, longreads | Excellent — respects "verbatim" instruction |
+
+Rule: for bulk enrichment, do a Sonnet draft pass and spot-check 5 with
+the LLM-judge brain-quality eval. If quotes are paraphrased, switch to
+Opus for that batch.
+
+## Link convention
+
+All cross-references use standard markdown links: `[Title](relative/path.md)`.
+NEVER use `[[wiki-links]]` — they don't render on GitHub.
+
+## Anti-Patterns
+
+- ❌ Paraphrasing quotes ("the author argues that…"). Quotes are verbatim
+  or they're not quotes.
+- ❌ Generic "Why It Matters" ("this is important because innovation").
+  Tie to specific brain context or remove the section.
+- ❌ Inventing topic labels and calling them insights. An insight is a
+  thing the article says that you didn't already know.
+- ❌ Discarding the raw source. Always wrap it in `<details>`.
+- ❌ Re-enriching non-idempotently — check the `needs_enrichment` flag in
+  frontmatter; skip if already false.

Left column preserves the chapter content; right column maps every idea to the reader's actual life using brain context.

+> sanctioned `media/<format>/<slug>` exception this skill files under.
+>
+> **Convention:** see [conventions/quality.md](../conventions/quality.md) for

+> **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md)
+> for the lookup chain (brain → search → external) the context-gathering
+> phase follows.
+
+## What this does
+
+Given a book (EPUB or PDF), produce a brain page where every chapter is
+summarized in detail on the left and mirrored back to the reader's actual life
+on the right, using their own words, situations, people, and patterns from
+the brain. Output is a brain page at `media/books/<slug>-personalized.md`.
+
+This is NOT a generic book summary. The right column is the value: it makes
+the book read like a therapist who knows the reader is leaving notes in the
+margins. If the user wants a flat summary instead, route them to a different
+skill.
+
+## Trust contract (read this before running)
+
+book-mirror runs as a CLI command (`gbrain book-mirror`), NOT as a pure
+markdown skill that the agent dispatches via tools. The CLI is the trusted
+runtime; the skill is the orchestration prose around it.
+
+What this means for the agent:
+
+- The CLI submits N read-only subagent jobs (one per chapter). Each subagent
+  has `allowed_tools: ['get_page', 'search']` only. They CANNOT call
+  put_page or any mutating op. They produce markdown analysis via their
+  final message.
+- The CLI reads each child's `job.result`, assembles the final
+  two-column page, and writes it via a single operator-trust `put_page`.
+- This means untrusted EPUB/PDF content cannot prompt-inject any
+  `people/*` page. The trust narrowing happens at the tool allowlist,
+  not at the slug-prefix layer.
+
+## The pipeline
+
+```
+1. ACQUIRE   → User has the EPUB/PDF locally (manual; book-acquisition is
+               not currently shipped — see "Acquiring the book" below).
+2. EXTRACT   → Pull chapter text from EPUB/PDF into one .txt per chapter.
+3. CONTEXT   → Gather everything the brain knows about the reader.
+4. ANALYZE   → `gbrain book-mirror` fans out N read-only subagents.
+5. ASSEMBLE  → CLI reads each child result and writes one put_page.
+6. PDF       → Optional: render via skills/brain-pdf for delivery.
+```
+
+## 1. Acquiring the book
+
+book-acquisition (legal-grey-area downloader) was deliberately not shipped
+in this skill wave. The user drops the EPUB/PDF manually. Common paths the
+user might use:
+
+```bash
+# User-supplied path
+ls path/to/book.epub
+ls path/to/book.pdf
+
+# Or already in the brain repo (recommended for tracking)
+ls $BRAIN_DIR/media/books/
+```
+
+Resolve `$BRAIN_DIR` from the gbrain config (`gbrain config get sync.repo_path`)
+or accept it from the user.
+
+## 2. Text extraction
+
+Goal: one `.txt` file per chapter under a temp directory. The agent has
+shell + python access; the CLI is downstream of this and takes the
+extracted directory as input.
+
+### EPUB
+
+```bash
+SLUG="this-book"                                # kebab-case
+WORK="$(mktemp -d)/$SLUG"
+mkdir -p "$WORK/chapters"
+unzip -o path/to/book.epub -d "$WORK/unpacked"
+
+# Find content files (XHTML/HTML), sorted (chapter order = sort order)
+find "$WORK/unpacked" -name "*.xhtml" -o -name "*.html" | sort > "$WORK/files.txt"
+
+# Strip HTML to text per chapter
+python3 - <<'PY'
+from bs4 import BeautifulSoup
+import os, sys
+work = os.environ['WORK']
+files = open(f'{work}/files.txt').read().splitlines()
+for i, path in enumerate(files, 1):
+    html = open(path, encoding='utf-8', errors='replace').read()
+    text = BeautifulSoup(html, 'html.parser').get_text('\n')
+    text = '\n'.join(line.strip() for line in text.splitlines() if line.strip())
+    with open(f'{work}/chapters/{i:02d}.txt', 'w') as f:
+        f.write(text)
+PY
+```
+
+If `bs4` is missing: `pip3 install beautifulsoup4 lxml`.
+
+Inspect the chapter files to identify which are real chapters vs front
+matter (TOC, copyright, acknowledgments). Often the EPUB ships one file
+per chapter; sometimes multiple chapters per file. Use
+`head -5 "$WORK/chapters/"*.txt` to spot-check.
+
+### PDF
+
+```bash
+pdftotext -layout path/to/book.pdf "$WORK/full.txt"
+```
+
+Then split by chapter heading (look for "Chapter N", "CHAPTER N", or
+all-caps title lines) using `awk` or `python`. If the PDF is a scan with
+no embedded text, fall back to OCR via `skills/brain-pdf` or another
+vision tool.
+
+### Quality check
+
+For each chapter file:
+
+- Word count > 1500 (typical chapter range 2k–8k words).
+- No HTML tags.
+- Paragraphs preserved with `\n\n`.
+
+Save a `chapters/INDEX.md` mapping chapter number → title → file → word
+count for reference.
+
+## 3. Context gathering
+
+This is the most critical step. The right column is only as good as the
+context fed to each chapter subagent.
+
+### What to pull
+
+1. **Templates: USER.md and SOUL.md** if the user maintains them
+   (gbrain ships templates at `templates/USER.md` and `templates/SOUL.md`;
+   they live in the brain repo when populated). Read full.
+2. **Recent daily memory** — last 14 days of brain pages under
+   `wiki/personal/reflections/` or wherever the user files daily notes.
+3. **Topic-relevant brain searches** tuned to the book's themes:
+   - `gbrain query "marriage"`, `gbrain query "couples therapy"` for a
+     marriage book.
+   - `gbrain query "founders"`, `gbrain query "fundraising"` for a
+     business book.
+   - `gbrain query "shame"`, `gbrain query "anger"` for a psychology book.
+4. **Brain pages for relevant entities** — `gbrain query "<name>"` for
+   people who will likely come up.
+5. **Standing patterns** — anything in the user's reflections or
+   originals that's been recurring.
+
+### Assemble a context pack
+
+Write everything to a single file the CLI can read:
+
+```bash
+CONTEXT="$WORK/context.md"
+{
+  echo "## USER.md (if any)"
+  [ -f "$BRAIN_DIR/USER.md" ] && cat "$BRAIN_DIR/USER.md"
+  echo
+  echo "## SOUL.md (if any)"
+  [ -f "$BRAIN_DIR/SOUL.md" ] && cat "$BRAIN_DIR/SOUL.md"
+  echo
+  echo "## Recent reflections (last 14 days)"
+  # Pull recent daily reflections — adapt to the user's filing scheme
+  # ...
+  echo
+  echo "## Topic-relevant brain pages"
+  # gbrain query the book's key themes, embed top results
+  # ...
+  echo
+  echo "## Themes & cruxes"
+  # A 1-page summary, written by the agent, calling out:
+  # - What's currently active in the user's life that this book intersects
+  # - Specific quotes from the user that map to book themes
+  # - People and dates that should appear in the right column
+} > "$CONTEXT"
+```
+
+Make this dense. It's read by every chapter subagent.
+
+## 4. Analysis: invoke `gbrain book-mirror`
+
+```bash
+gbrain book-mirror \
+  --chapters-dir "$WORK/chapters" \
+  --context-file "$CONTEXT" \
+  --slug "$SLUG" \
+  --title "Book Title Goes Here" \
+  --author "Author Name" \
+  --model claude-opus-4-7
+```
+
+The CLI:
+
+- Validates inputs and loads chapter files.
+- Prints a cost estimate (~$0.30/chapter at Opus) and prompts to confirm.
+- Submits N child subagent jobs with read-only `allowed_tools`.
+- Waits for every child to complete.
+- Reads each child's `job.result` (the markdown analysis text).
+- Assembles all chapters into one page with frontmatter + intro + per-chapter
+  sections + closing.
+- Writes ONE `put_page` to `media/books/<slug>-personalized.md`.
+- Reports a JSON envelope on stdout:
+  `{"slug": "...", "chapters_total": N, "chapters_completed": N, "chapters_failed": 0}`.
+
+If any chapter failed, the CLI exits 1 and the user can re-run — idempotency
+keys (`book-mirror:<slug>:ch-<N>`) deduplicate completed chapters at the
+queue level, so retry is cheap.
+
+### Model: Opus by default
+
+The default model is `claude-opus-4-7`. Sonnet works (use `--model
+claude-sonnet-4-6`) but the right-column quality drops noticeably — the
+texture that makes the analysis read like a therapist who knows the user
+needs Opus-grade reasoning.
+
+### Cost gate
+
+The CLI refuses to spend in a non-TTY context without `--yes`. CI / scripted
+invocations must pass `--yes` explicitly. TTY users get a `[y/N]` prompt
+before submission.
+
+## 5. PDF (optional)
+
+After the brain page is written, render to PDF using `skills/brain-pdf`:
+
+```bash
+gbrain put_page  # already done by the CLI; nothing to add here
+# Then invoke brain-pdf:
+# (see skills/brain-pdf/SKILL.md for the make-pdf invocation)
+```
+
+## 6. Fact-check and cross-link
+
+After the page lands, run a fact-check pass on factual claims about the
+reader (parents, siblings, marriage history, jobs, heritage). Common error
+patterns to look for:
+
+- Conflating the reader's parents' relationship with patterns in extended
+  family.
+- Inventing therapy backstory ("after his parents' divorce…") when the
+  reader's parents are still together.
+- Wrong number/age of children, wrong spouse / kid / sibling names.
+
+If you can't verify a claim, remove it. Better to lose texture than to
+introduce a falsehood.
+
+Cross-link entities mentioned in the analysis:
+
+- For every person the right column references with a brain page, add a
+  back-link from `people/<slug>` to the new `media/books/<slug>-personalized`
+  page (per `conventions/quality.md` Iron Law).
+
+## Quality bar (the bar)
+
+The **left column** should:
+
+- Preserve the author's actual stories, statistics, frameworks, examples.
+- Quote memorable phrases verbatim.
+- Be detailed enough that the reader could skip the book and not lose much.
+
+The **right column** should:
+
+- Use the reader's *actual quoted words* from the context pack.
+- Reference *specific* dates, situations, people by name.
+- Read like a therapist who knows the reader is leaving notes in the margins.
+- Be plain about direct hits ("This is exactly the [name a real situation]").
+- Be honest about misses ("This chapter is less directly relevant
+  because…"). Don't force connections.
+
+The **whole document** should feel like one coherent voice, calibrated to
+the reader's actual life rather than a generic profile, and honest about
+where the book's framing breaks down for this specific reader.
+
+## Anti-patterns (do not do these)
+
+- ❌ **Skimming chapters.** Standing instruction: preserve detail.
+- ❌ **Generic right column.** "This might apply if you've ever felt…" →
+  kill on sight.
+- ❌ **Factual errors about the reader's life.** Always fact-check after
+  assembly.
+- ❌ **Giving the subagent put_page access.** Trust contract is read-only;
+  the CLI does the writing.
+- ❌ **Forcing connections.** If a chapter doesn't apply, say so plainly.
+- ❌ **Sycophancy or moralizing in the right column.** No "you should…",
+  no "consider…", no "perhaps it's time to…".
+- ❌ **Truncating the LEFT column.** The book's actual content needs to
+  survive.
+
+## Output checklist
+
+- [ ] Book file exists locally (path known).
+- [ ] Chapter texts under `$WORK/chapters/*.txt` with sane word counts.
+- [ ] Context pack at `$WORK/context.md` is dense.
+- [ ] `gbrain book-mirror --chapters-dir … --context-file … --slug … --title …` returned exit 0.
+- [ ] `media/books/<slug>-personalized.md` exists in the brain.
+- [ ] Fact-check pass complete (no errors against USER.md or other source-of-truth pages).
+- [ ] Cross-links added from referenced people/companies.
+- [ ] Optional: PDF rendered via brain-pdf and delivered.

+version: 0.1.0
+description: Generate a publication-quality PDF from any brain page via the gstack make-pdf binary. Strips YAML frontmatter, sanitizes emoji, applies running headers and page numbers. Brain page is always the source of truth; PDF is a rendering.
+triggers:
+  - "make pdf from brain"
+  - "brain pdf"
+  - "convert brain page to pdf"
+  - "publish this page as pdf"
+  - "export brain page"
+---
+
+# brain-pdf — Render a Brain Page to Publication-Quality PDF
+
+> **Convention:** see [conventions/quality.md](../conventions/quality.md) for
+> output rules. The PDF is a rendering — never the primary artifact. If a
+> PDF exists, the source brain page exists behind it.
+
+## The rule
+
+The brain page is ALWAYS the source of truth. The PDF is a rendering of
+it, never a standalone artifact. If a PDF exists somewhere, the brain
+page must exist behind it.
+
+## What this does
+
+Renders a brain page (markdown with frontmatter) into a
+publication-quality PDF using the gstack `make-pdf` binary. Output is
+suitable for:
+
+- Sharing a personalized book mirror via email or Telegram
+- Delivering a strategic-reading playbook as a clean read
+- Producing a briefing or report with running headers and page numbers
+- Archiving a long-form essay in a portable format
+
+## Prerequisite: gstack make-pdf
+
+This skill depends on the gstack `make-pdf` binary at:
+
+```
+$HOME/.claude/skills/gstack/make-pdf/dist/pdf
+```
+
+The user must have gstack co-installed. If absent, the skill cannot run.
+A future v0.26+ may bundle a fallback PDF renderer; for v0.25.1 gstack
+is a soft prereq.
+
+Verify it exists before invoking:
+
+```bash
+P="$HOME/.claude/skills/gstack/make-pdf/dist/pdf"
+[ -x "$P" ] || { echo "make-pdf not installed; install gstack" >&2; exit 1; }
+```
+
+## Workflow
+
+```
+1. RESOLVE  → Confirm the brain page exists (gbrain get <slug>).
+2. STRIP    → Remove YAML frontmatter — the renderer would otherwise
+              dump it as a full page of raw metadata text.
+3. RENDER   → Invoke make-pdf with sane defaults (no --cover, no --toc).
+4. DELIVER  → Hand the PDF to the requester via the agent's preferred
+              channel (do not use raw `MEDIA:` tags on Telegram —
+              they fail silently).
+```
+
+## Invocation
+
+```bash
+SLUG="path/to/page"
+P="$HOME/.claude/skills/gstack/make-pdf/dist/pdf"
+
+# 1. Confirm the page exists.
+gbrain get "$SLUG" > /dev/null || { echo "Page $SLUG not found" >&2; exit 1; }
+
+# 2. Get the raw markdown. Two paths: read from the brain repo (if user
+#    syncs locally) OR ask gbrain for the body via the API.
+BRAIN_DIR=$(gbrain config get sync.repo_path 2>/dev/null || echo)
+if [ -n "$BRAIN_DIR" ] && [ -f "$BRAIN_DIR/$SLUG.md" ]; then
+  RAW="$BRAIN_DIR/$SLUG.md"
+else
+  RAW=$(mktemp /tmp/brain-page-XXXXXX.md)
+  gbrain get "$SLUG" --raw > "$RAW"   # whatever flag exposes raw body
+fi
+
+# 3. Strip YAML frontmatter — sed: skip the opening '---' through the
+#    closing '---' (lines 1..N), then keep everything after.
+CLEAN=$(mktemp /tmp/brain-page-clean-XXXXXX.md)
+sed '1{/^---$/!q}; /^---$/,/^---$/d' "$RAW" > "$CLEAN"
+
+# 4. Render. NO --cover, NO --toc by default — they look corporate
+#    and waste space. Add them only if explicitly requested.
+OUT="/tmp/$(basename "$SLUG").pdf"
+CONTAINER=1 "$P" generate "$CLEAN" "$OUT"
+
+echo "Rendered: $OUT"
+```
+
+`CONTAINER=1` is mandatory in containerized environments — it tells
+Playwright to skip Chromium sandboxing. Harmless on bare-metal.
+
+## Common patterns
+
+```bash

+
+# Draft watermark for in-progress work
+CONTAINER=1 "$P" generate --watermark DRAFT "$CLEAN" "$OUT"
+
+# Optional cover + TOC if the user explicitly asks

+
+# Custom title + author override (otherwise pulled from frontmatter)
+CONTAINER=1 "$P" generate --title "Custom Title" --author "Custom Author" "$CLEAN" "$OUT"
+```
+
+## Defaults: NO cover, NO TOC
+
+These flags are off by default because they look corporate and waste
+space on most personal-knowledge content. Only add them when the user
+explicitly asks for "formal" output (e.g., something they're sending to
+a board or printing as a deliverable).
+
+## Font requirements
+
+The renderer needs:
+
+- `fonts-liberation` (Helvetica/Arial substitute)
+- `fonts-noto-cjk` (Chinese/Japanese/Korean characters)
+- Minimum body font size: 10pt (page chrome 9pt)
+- Body text: 11pt
+
+If running in an environment without these fonts, install them via the
+host's package manager (`apt install fonts-liberation fonts-noto-cjk` on
+Debian/Ubuntu containers).
+
+## Delivery
+
+After rendering, deliver via the agent's preferred channel:
+
+- **Telegram:** use the `message` tool with `filePath="/tmp/<slug>.pdf"`
+  attachment. NEVER use raw `MEDIA:` tags — they fail silently.
+- **Email:** attach via the host's email tool.
+- **Direct file response:** print the PDF path; the user can pull it
+  manually.
+
+Always include the brain page link in the delivery message so the user
+can also see it on GitHub / locally. The PDF is a rendering; the source
+is the artifact.
+
+## Anti-Patterns
+
+- ❌ Generating a PDF without first confirming the brain page exists.
+  No source = no PDF.
+- ❌ Skipping the frontmatter strip. The renderer dumps frontmatter as
+  raw text on the first page; ugly.
+- ❌ Skipping emoji sanitization. Emoji that don't map to the rendering
+  font show up as `□` boxes.
+- ❌ Adding `--cover` or `--toc` by default. Off unless asked.
+- ❌ Using raw `MEDIA:` tags for Telegram delivery. Use the `message`
+  tool with `filePath`.
+
+## Related skills
+
+- `skills/book-mirror/SKILL.md` — produces a brain page that's a
+  natural input to brain-pdf (chapter-by-chapter personalized analysis).
+- `skills/strategic-reading/SKILL.md` — same shape, problem-lens variant.
+- `skills/publish/SKILL.md` — share brain pages as password-protected
+  HTML (different rendering target).
+
+
+## Contract
+
+This skill guarantees:
+
+- Routing matches the canonical triggers in the frontmatter.
+- Output written under the directories listed in `writes_to:` (when applicable).
+- Conventions referenced (`quality.md`, `brain-first.md`, `_brain-filing-rules.md`) are followed.
+- Privacy contract preserved: no real names, no fork-specific filesystem path literals, no upstream-fork references.

+The full behavior contract is documented in the body sections above; this section exists for the conformance test.

 ## Contract
 
 This skill guarantees:
-- Every brain page is scanned for citation compliance
-- Missing citations are flagged with specific location
-- Malformed citations are fixed to match the standard format
-- Results reported with counts (scanned, fixed, remaining)
+
+- Every brain page is scanned for citation compliance.
+- Missing citations are flagged with specific location.
+- Malformed citations are fixed to match the standard format.
+- **(v0.25.1)** Tweet / post references without URLs are resolved via
+  X API and patched with deterministic `https://x.com/<handle>/status/<id>`
+  links.
+- Results reported with counts (scanned, fixed, remaining).
 
 ## Phases
 
-1. **Scan pages.** List pages and read each one, checking for inline `[Source: ...]` citations.
+1. **Scan pages.** List pages and read each one, checking for inline
+   `[Source: ...]` citations.
 2. **Identify issues:**
    - Facts without any citation
    - Citations missing date
    - Citations missing source type
    - Citations with wrong format
-3. **Fix format issues.** Rewrite malformed citations to match `skills/conventions/quality.md`.
-4. **Report results.** Count: pages scanned, citations found, issues fixed, remaining gaps.
+   - **(v0.25.1)** Tweet references without `x.com` URLs
+3. **Fix format issues.** Rewrite malformed citations to match
+   `conventions/quality.md`.
+4. **(v0.25.1) Resolve tweet references** via the X API integration.
+5. **Report results.** Count: pages scanned, citations found, issues
+   fixed, tweets resolved, remaining gaps.
 
-## Output Format
+## Tweet resolution pipeline (v0.25.1 extension)
+
+For each broken tweet reference, follow this chain. The actual API call
+goes through whatever X integration the host has configured (typical
+shape: a recipe under `recipes/x-api/` with handle / search-all
+endpoints).
+
+### Step 1: Identify broken references
+
+Scan the page for patterns that indicate tweet references without URLs:
+
+- Contains words like `tweeted`, `posted`, `said on X`, `RT`, `retweet`,
+  `X post`
+- Contains quoted text that looks like a tweet (short, punchy, often
+  starts with a quote)
+- Has `[Source: ... X/Twitter ...]` without an `x.com` URL
+- References engagement metrics (likes, impressions) without a link
+
+### Step 2: Extract searchable content
+
+From each broken reference, extract:
+
+- The **handle** (if mentioned: `@<username>`)
+- The **quoted text** (if available)
+- The **approximate date** (often present in surrounding timeline entries)
+
+### Step 3: Search for the actual tweet
+
+Use the host's X API integration. Query patterns:
+
+```
+# Handle + quoted text:
+from:<handle> "<exact quote fragment>"
+
+# Quoted text only:
+"<exact quote fragment>"
+
+# Original of a retweet:
+"<exact quote>" -is:retweet
+```
+
+### Step 4: Verify and extract metadata
+
+Once a candidate is found:
+
+- Confirm the text matches the quoted fragment.
+- Pull the tweet id, author handle, engagement metrics (likes / RTs /
+  impressions).
+- Construct the URL: `https://x.com/<handle>/status/<tweet_id>`.
+
+### Step 5: Patch the brain page
+
+Replace the broken citation with a proper one:
+
+**Before:**
+
+```
+"<quote fragment>" [Source: <some hand-wavy attribution>]
+```
+
+**After:**
+
+```
+"<full verified quote>" — <N> likes, <N> RTs, <N> impressions
+[Source: [X/<handle>, YYYY-MM-DD](https://x.com/<handle>/status/<tweet_id>)]
+```
+
+## Batch mode
+
+When sweeping many pages:
+
+### Find candidate pages
+
+```bash
+# Pages mentioning tweets but with no x.com links
+for f in $(find . -name "*.md" -not -path "./node_modules/*"); do
+  refs=$(grep -ci "tweet\|posted\|x post\|RT\|retweet\|said on X" "$f")
+  links=$(grep -c "x.com/.*/status/" "$f")
+  if [ "$refs" -gt 2 ] && [ "$links" -eq 0 ]; then
+    echo "$f"
+  fi
+done
+```
+
+### Priority order
+
+1. Recently created / updated pages — fresh broken refs are easiest to
+   resolve while context is fresh.
+2. High-traffic pages (frequent reads / writes from other skills).
+3. Everything else — bulk cleanup over time.
+
+### Rate limiting
+
+- X API: respect the host's tier limits; don't hammer.
+- Target ~50 pages per batch run.
+- 1-3 API calls per page (search + verify).
+- Batch-commit every 10-20 pages so a partial failure doesn't lose
+  progress.
+
+## Output format
 
 ```
 Citation Audit Report
 =====================
-Pages scanned: N
-Citations found: N
-Issues fixed: N
-Remaining gaps: N (pages with uncitable facts)
+Pages scanned:        N
+Citations found:      N
+Issues fixed:         N
+Tweet links resolved: N
+Remaining gaps:       N (pages with uncitable facts)
 ```
 
 ## Anti-Patterns
 
-- Inventing citations for facts that have no source
-- Removing facts that lack citations (flag them, don't delete)
-- Fixing citations without reading the full page context
-- Batch-fixing without checking quality (test-before-bulk convention)
+- ❌ Inventing citations for facts that have no source. Flag them.
+- ❌ Removing facts that lack citations (flag them; don't delete).
+- ❌ Fixing citations without reading the full page context.
+- ❌ Batch-fixing without checking quality on a sample first
+  (see `conventions/test-before-bulk.md`).
+- ❌ Composing tweet URLs by guessing the tweet id. Always go through
+  the X API; deterministic links only.
+
+## Integration
+
+This skill can be called:
+
+- **Manually** — "fix citations on this page"
+- **As a batch cron** — weekly sweep of pages with broken refs
+- **By other skills** — `enrich` or `media-ingest` can call citation-fixer
+  before commit to validate output
+
+## Metrics
+
+If running as a recurring batch, track state in a small JSON file under
+`~/.gbrain/citation-fixer-state.json`:
+
+```json
+{
+  "last_run": "2026-04-15T...",
+  "pages_scanned": 0,
+  "citations_fixed": 0,
+  "tweet_links_resolved": 0,
+  "citations_unresolvable": 0,
+  "pages_remaining": 1424
+}
+```

+> back-link enforcement and quote-fidelity requirements.
+>
+> **Convention:** see [_brain-filing-rules.md](../_brain-filing-rules.md) —

+
+## What this solves
+
+Many ingestion pipelines (signal-detector, idea-ingest, voice-note-ingest)
+create a concept page for every idea mentioned. Over months this produces:
+
+- Thousands of stub pages, many duplicates or near-duplicates
+- Timeline entries that repeat the same source across multiple concept pages
+- No synthesis — just "the user mentioned X on this date"
+- No tier assignments — everything flat
+- No clustering — related ideas aren't linked
+
+This skill transforms that raw material into a curated intellectual map.
+
+## Architecture
+
+```
+Phase 1: Dedup + merge (deterministic)
+  N stubs → ~N/4 canonical concepts
+    ├── Jaccard dedup (word-overlap on titles + first-paragraph)
+    ├── Substring dedup ("founder mode" vs "founder mode vs manager mode")
+    ├── Semantic dedup (LLM: "are these the same idea?")
+    └── Merge timelines + aliases from duplicates into the canonical page
+
+Phase 2: Score + tier (deterministic + heuristic)
+  Each canonical concept → scored and tiered
+    ├── Frequency: distinct sources referencing this concept
+    ├── Timespan: first mention → last mention in days
+    ├── Breadth: distinct months it appears in
+    ├── Engagement: avg engagement on concept-bearing sources (if available)
+    └── Tier: T1 Canon | T2 Developing | T3 Speculative | T4 Riff
+
+Phase 3: Synthesize (LLM, T1+T2 only)
+  T1 + T2 concepts → rich synthesis
+    ├── Evolution narrative: how the idea sharpened over time
+    ├── Best articulation: highest-engagement or most precise quote
+    ├── Related concepts: cross-links to other concepts
+    ├── Context: what was happening when this idea emerged / evolved
+    └── Counter-positions: what this idea argues against
+
+Phase 4: Cluster + map (LLM)
+  All tiered concepts → intellectual clusters
+    ├── Group related concepts into domains (auto-named via LLM)
+    ├── Generate cluster summary pages
+    ├── Build a master concepts/README.md with the full map
+    └── Identify idea genealogies (concept A → evolved into concept B)
+```
+
+## Invocation
+
+The skill is markdown agent instructions. The agent uses gbrain's
+existing operations + LLM passes:
+
+```bash
+# 1. List all concept pages
+gbrain query "type:concept" --limit 10000 --json
+
+# 2. Phase 1 dedup — agent applies Jaccard + substring locally,
+#    then LLM passes to identify semantic duplicates.
+
+# 3. Phase 2 tier — agent scores each canonical concept based on
+#    frequency / timespan / breadth and writes tier into frontmatter.
+
+# 4. Phase 3 synthesis — for each T1/T2, agent reads the timeline
+#    + associated source pages and writes a synthesis section
+#    onto the concept page via put_page.
+
+# 5. Phase 4 clustering — agent reads the tiered concept list
+#    and writes concepts/README.md with the full intellectual map.
+```
+
+## Output: concept page format (post-synthesis)
+
+### T1 Canon — full synthesis
+
+```markdown

+title: "concept name"
+type: concept
+tier: 1
+tier_label: "Canon"

+
+## Synthesis
+
+[2-4 paragraph narrative tracing how the idea evolved, what it means in
+the user's worldview, why it matters. Third-person analytical voice.]
+
+## Best Articulation

+> expression of this idea." — [Date](source-url)
+
+## Evolution
+
+| Period | Expression | Signal |
+|--------|-----------|--------|
+| YYYY-MM | "First articulation" | First use — aspiration frame |
+| YYYY-MM | "Sharpening" | Anti-pattern emerges |
+| YYYY-MM | "Peak form" | Cleanest expression |
+
+## Related Concepts

+---

+```
+
+## Output: cluster map at concepts/README.md

+# Intellectual Universe
+
+## Canon (T1) — N concepts
+The permanent intellectual fingerprint. Ideas that recur across years.

+- [concept-slug](concept-slug.md) — one-line characterization
+- ...
+
+### [Other Cluster]
+- ...
+
+## Developing (T2) — N concepts
+Sharpening. Might become canon.
+
+## Speculative (T3) — N concepts
+Testing in public.
+
+## Stats
+- Total concepts: N
+- T1 Canon: N
+- T2 Developing: N
+- T3 Speculative: N
+- T4 Riff: N
+- Earliest source: YYYY-MM-DD
+- Latest source: YYYY-MM-DD
+```
+
+## Quality gates
+
+### Dedup quality
+- No two concept pages should be "the same idea in different words."
+- Aliases preserved in frontmatter for search.
+- Run `gbrain query "type:concept"` and spot-check the count reduction.
+
+### Tier quality
+- T1 should feel like "yes, that IS one of my recurring frameworks" —
+  recognizable, recurring, sharp.
+- T2 should feel like "I'm working on this; it's getting clearer."
+- No concept should be T1 with < 4 months span or < 6 mentions.
+- No concept should be T4 with > 3 months span.
+
+### Synthesis quality
+- Captures evolution, not just repetition.
+- Uses verbatim quotes, not paraphrase.
+- Links to related concepts (markdown links, not wiki-links).
+- Does NOT hallucinate sources or dates.
+
+## Cron integration
+
+This is heavy work. Run on a cadence, not on every signal:
+
+- After a major ingestion batch completes (signal-detector burst, archive
+  crawler run, etc.).
+- Weekly cron for incremental synthesis of newly-promoted T1/T2 concepts.
+- Manual trigger for a full re-synthesis when the corpus shifts
+  significantly.
+
+## Anti-Patterns
+
+- ❌ Running synthesis on T3/T4 — wastes API budget on ideas that may
+  never sharpen.
+- ❌ Hallucinating quotes or dates. The timeline must be verifiable
+  against existing brain pages.
+- ❌ Generic cluster names ("Various Topics"). If you can't name the
+  cluster, the cluster isn't real.
+- ❌ Re-synthesizing already-synthesized T1s without new source material.
+  Idempotency-respect.
+

 ## Contract
 
 This skill guarantees:
-- Work product is reviewed by a different model before finalizing
-- Review grades against the originating skill's Contract section
-- Agreement and disagreement are reported transparently
-- Refusal from one model triggers silent switch to next in chain
-- User always makes the final decision (user sovereignty)
+
+- Work product is reviewed by a different model before finalizing.
+- The review is graded against the originating skill's Contract section
+  (what was promised), not vibes.
+- Agreement and disagreement are reported transparently.
+- Refusal from one model triggers a silent switch to the next in chain.
+- The user always makes the final decision (user sovereignty).
+
+## When to invoke (v0.25.1 gating)
+
+Invoke this skill when:
+
+- **Significant code changes** — any commit touching 5+ files or 100+
+  lines. Architecture decisions, refactors, API changes.
+- **Security-sensitive changes** — auth flows, brain-write trust boundaries,
+  webhook transforms, cross-skill data passing.
+- **Stuck or churning** — 2+ iterations on the same problem without
+  progress.
+- **Pre-bulk-operation** — before running batch enrichment, migrations,
+  or bulk writes (see [conventions/test-before-bulk.md](../conventions/test-before-bulk.md)).
+- **Skill creation / modification** — new or rewritten skills that
+  affect operational behavior.
+- **Brain-page quality concerns** — when brain writes need validation
+  against the originating skill's Contract.
+
+Do NOT invoke for:
+
+- Simple memory writes or brain-page updates
+- Single-file typo fixes
+- Routine cron output or heartbeat operations
+- Git commit / push of already-reviewed work
 
 ## Phases
 
-1. **Capture the work product.** The brain page, analysis, or decision to be reviewed.
-2. **Load the Contract.** Read the originating skill's Contract section (what was promised).
-3. **Spawn review model.** Send the work + Contract to a different model. Use `skills/conventions/model-routing.md` for model selection.
-4. **Grade.** Model evaluates: did the output follow the Contract? Pass/fail with specific citations.
-5. **Report.** Present agreement/disagreement to the user. Never auto-apply the reviewer's suggestions.

-## Refusal Routing
+## Code-review handoff (v0.25.1 extension)
 
-If the primary model refuses:
-1. Silently switch to the next model in the chain (see `skills/conventions/cross-modal.yaml`)
-2. Never show the refusal to the user
-3. Never announce the switch
-4. If ALL models refuse, escalate to the user
+For diff review specifically, gstack ships a `/codex` skill that wraps
+the OpenAI Codex CLI. Two modes:
 
-## Output Format
+### Codex Review
+
+Independent diff review from a different AI system. The user invokes
+`/codex review` (gstack-shipped); cross-modal-review's job is to

+  v0.25.1 ships the book-mirror flagship plus 8 research-flavored
+  pairings, a real `gbrain skillpack uninstall`, and a hardened privacy
+  CI guard. Existing brains: zero schema migration. Optional new
+  capability: 9 markdown skills installable into your workspace via
+  `gbrain skillpack install --all`.
+---
+
+# v0.25.1 — Skills wave migration
+
+## TL;DR
+
+If you already have v0.24.0 installed, `gbrain upgrade` does it.
+There is **no schema migration**. Existing brains work unchanged.
+
+This file exists for agents reading the skill set after upgrade. It
+explains:
+
+1. What the 9 new skills do (so the agent knows when to invoke them)
+2. The new `archive-crawler.scan_paths:` config requirement
+3. The new `gbrain skillpack uninstall` subcommand
+4. The new `gbrain book-mirror` CLI
+
+## Step 0: Watch for the post-install advisory (NEW in v0.25.1)
+
+Every `gbrain init` and `gbrain post-upgrade` now ends by printing an
+agent-readable advisory listing the recommended new skills. If you ran
+`gbrain upgrade` and saw a banner like:
+
+```
+========================================================================
+gbrain 0.25.1 — RECOMMENDED SKILLS FOR THE AGENT TO INSTALL
+========================================================================
+```
+
+…that's the advisory. It explicitly asks you (the agent) to surface
+the skill list to the user, ask them whether to install, and run the
+right `gbrain skillpack install` command if they say yes. **Do that
+first, then return here for the rest.**
+
+If the advisory didn't print, your workspace already has all 9 v0.25.1
+skills installed (or no managed block was detected). Continue with the
+verification steps below.
+
+## Step 1: Verify the upgrade landed
+
+```bash
+gbrain --version                  # expect: gbrain 0.25.1
+gbrain skillpack list             # expect: 34 skills (was 25 before)
+gbrain skillpack uninstall --help # expect: "Inverse of install" in help
+```
+
+If `gbrain --version` reports 0.24.x, run `gbrain upgrade` first.
+
+## Step 2: Install the new skills (optional)
+
+The 9 new skills are in the bundle but only become active in your
+workspace after explicit install:
+
+```bash
+# install just the flagship:
+gbrain skillpack install book-mirror
+
+# OR install everything new at once:
+gbrain skillpack install --all
+```
+
+The 9 new skills:
+
+- **book-mirror** — flagship. Two-column personalized chapter-by-chapter
+  book analysis. Pairs with `gbrain book-mirror` CLI.
+- **article-enrichment** — turns raw article dumps into structured
+  pages with verbatim quotes.
+- **strategic-reading** — reads a book through one specific
+  problem-lens with a do/avoid/watch-for playbook.
+- **concept-synthesis** — deduplicates raw concept stubs into a
+  tiered intellectual map.
+- **perplexity-research** — brain-augmented web research focused on
+  what's NEW vs already-known.
+- **archive-crawler** — universal archivist for personal file
+  archives (REQUIRES `gbrain.yml` allow-list, see Step 3).
+- **academic-verify** — traces a research claim through publication
+  → methodology → raw data → independent replication.
+- **brain-pdf** — renders any brain page to publication-quality PDF
+  via the gstack make-pdf binary.
+- **voice-note-ingest** — captures voice notes with exact-phrasing
+  preservation; routes to originals/concepts/people/companies/ideas.
+
+## Step 3: Configure `archive-crawler` if you installed it
+
+`archive-crawler` is the only skill in this wave with a hard
+configuration requirement. It refuses to run unless you explicitly
+list paths it's permitted to scan in your brain repo's `gbrain.yml`:
+
+```yaml
+# brain-repo/gbrain.yml
+archive-crawler:
+  scan_paths:
+    - ~/Documents/writing/
+    - ~/Dropbox/Archive/
+    - /mnt/backup/old-letters/
+  # Optional deny list (paths inside scan_paths to exclude):
+  # deny_paths:
+  #   - ~/Documents/finances/
+  #   - ~/Documents/medical/
+```
+
+Without `scan_paths`, the skill refuses to run. This is deliberate
+safety: the agent will not infer what's safe to read.
+
+If you skipped installing `archive-crawler`, no action needed.
+
+## Step 4: Use `gbrain book-mirror` (optional, the flagship)
+
+The skill (`skills/book-mirror/SKILL.md`) walks the agent through:
+
+1. Locate or download the EPUB / PDF (manual; the skill explains)
+2. Extract chapter text via BeautifulSoup4 (EPUB) or
+   `pdftotext -layout` (PDF) — produces `*.txt` files in a temp dir.
+3. Build a context pack (USER.md + SOUL.md + recent reflections
+   + topic-relevant brain searches).
+4. Invoke the CLI:
+
+```bash
+gbrain book-mirror \
+  --chapters-dir /tmp/books/this-book/chapters \
+  --context-file /tmp/books/this-book/context.md \
+  --slug this-book \
+  --title "This Book Title" \
+  --author "Some Author"
+```
+
+Costs ~$0.30 per chapter at Opus (default model). The CLI prints a
+cost estimate and prompts for confirmation before launching.
+
+Output lands at `media/books/<slug>-personalized.md` in your brain.
+
+## Step 5: `gbrain skillpack uninstall` (when you want it)
+
+If you ever want to remove a skill from your workspace:
+
+```bash
+gbrain skillpack uninstall book-mirror
+```
+
+Symmetric to install:
+
+- Refuses if the slug isn't in gbrain's cumulative-slugs receipt
+  (won't nuke a row you hand-added — exit 2 with a clear message
+  pointing you at manual cleanup).
+- Refuses if any installed file diverges from the bundle (you've
+  edited it locally) unless you pass `--overwrite-local`.
+- Atomic: if any file is blocked, the whole uninstall refuses
+  before any file is removed. No half-uninstalled state.
+
+## Step 6: Privacy CI guard (operator-relevant only if you ship gbrain forks)
+
+`scripts/check-privacy.sh` now also blocks `/data/brain/` and
+`/data/.openclaw/` literals in tracked files (these are
+fork-specific filesystem paths from gbrain's upstream). Seven
+historical files are allow-listed. If your fork has `bun run test`
+wired up, this runs automatically.
+
+If your fork hits an unexpected privacy-guard failure, check that
+the path actually needs to be in committed code (vs read from
+environment / config) and add to the script's allow-list with a
+comment if legitimate.
+
+## Verify the outcome
+
+```bash
+# Skills installed?
+gbrain skillpack list | grep -E "book-mirror|article-enrichment|strategic-reading"
+
+# Doctor reports clean?
+gbrain doctor --json | jq '.status'   # expect: "ok"
+
+# CLI commands wired?
+gbrain --tools-json | grep -i book-mirror   # may not list since it's CLI-only
+gbrain skillpack uninstall --help | head -1
+```
+
+## If anything fails
+
+File an issue at https://github.com/garrytan/gbrain/issues with:
+
+- output of `gbrain doctor --json`
+- contents of `~/.gbrain/upgrade-errors.jsonl` if it exists
+- which step in this migration broke
+
+Thank you. The cross-model review trail (Eng + Codex outside voice)
+caught real bugs before they shipped, but production exposes things
+review cannot. Your feedback closes the loop.

+# perplexity-research — Brain-Augmented Web Research
+
+> **Convention:** see [conventions/quality.md](../conventions/quality.md) for
+> citation rules; every claim from web research lands with a verifiable
+> citation, not a paraphrase.
+>
+> **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md)
+> for the lookup chain. This skill ENFORCES brain-first by sending brain
+> context as part of the Perplexity prompt — the web search focuses on
+> the delta between brain knowledge and current web state.
+
+## What this does
+
+Combines existing brain knowledge with Perplexity's web search. The
+agent sends brain context about a topic into a Perplexity query;
+Perplexity searches + reads + synthesizes multiple pages with citations,
+focused on what's NEW relative to the supplied context.
+
+**The key insight:** Perplexity doesn't just search — it reads and
+synthesizes with citations. By sending brain context in the
+instructions, it knows what you already know, so it surfaces the delta
+instead of repeating settled fact.
+
+## When to use this vs other tools
+
+| Need | Use |
+|------|-----|
+| Deep research with citations | **This skill** — Perplexity + Opus |
+| Quick URL content | `web_fetch` |
+| Brain-only lookup | `gbrain query` / `gbrain search` |
+| Real-time social monitoring | external X / social-media collectors |
+| Structured data lookup against a tracker | `skills/data-research/SKILL.md` |
+
+## Output structure
+
+The research output lands as a brain page under `research/<slug>.md` with
+this structure:
+
+```markdown
+---
+title: "[Topic] — Research [YYYY-MM-DD]"
+type: research
+date: YYYY-MM-DD
+brain_context_slugs: ["pages whose context was sent to Perplexity"]
+recency_filter: "[hour|day|week|month|none]"
+---
+
+# [Topic] — Research [YYYY-MM-DD]
+
+> Executive summary: 2-3 sentences on the delta between brain knowledge
+> and current web state.
+
+## Key New Developments
+What's changed since the brain was last updated on this topic.
+
+## Confirming Signals
+Web evidence validating existing brain knowledge.
+
+## Contradictions or Updates
+Things that conflict with the brain — these need a closer look.
+
+## Recommended Brain Updates
+Specific page updates the user might want to make based on this research.
+Each item: which page, what to add or change, source URL.
+
+## Citations
+- [Source title](URL) — accessed YYYY-MM-DD
+- [Source title](URL) — accessed YYYY-MM-DD
+- ...
+```
+
+## Invocation
+
+The skill is markdown agent instructions; the agent uses Perplexity's
+API directly (or a host-provided `perplexity` CLI if installed):
+
+```bash
+# 1. Pull brain context
+gbrain get <slug>                    # or
+gbrain query "<topic keywords>"
+
+# 2. Compose the Perplexity query with brain context inline:
+#    """
+#    Topic: <topic>
+#    Brain context (what we already know): <embedded gbrain content>
+#    Find: what's NEW since 2026-MM-DD that the brain doesn't reflect.
+#    Cite every claim.
+#    """
+
+# 3. Call Perplexity API or the host's perplexity binary:
+#    curl https://api.perplexity.ai/chat/completions \
+#      -H "Authorization: Bearer $PERPLEXITY_API_KEY" \
+#      -H "Content-Type: application/json" \
+#      -d '{"model": "sonar-pro", "messages": [{"role":"user","content":"..."}]}'
+
+# 4. Write the structured research page via put_page:
+gbrain put_page research/<slug>      # via the put_page operation
+
+# 5. Cross-link entities mentioned (people, companies) per Iron Law.
+```
+
+## Models
+
+| Model | Cost / query | Use when |
+|-------|-------------|----------|
+| Perplexity sonar-pro | ~\$0.04 | Deep analysis, entity enrichment, deal research |
+| Perplexity sonar | ~\$0.007 | Quick lookups, bulk monitoring, briefing pipelines |
+
+Default to sonar-pro. Drop to sonar for bulk / cron contexts where cost
+matters more than depth.
+
+## Integration patterns
+
+### Entity enrichment
+
+Called by `skills/enrich/SKILL.md` when an entity page (person, company)
+needs current web context:
+
+```bash
+BRAIN=$(gbrain get people/<slug> 2>/dev/null)
+# Send <slug>'s page content as brain_context to Perplexity, get current
+# news / role / context, then update the brain page with what's new.
+```
+
+### Deal / company monitoring (cron)
+
+For each active item under `deals/` or `companies/`:
+
+```bash
+# Weekly: pull recent news per company; flag changes for review.
+```
+
+### Morning briefing
+
+Replace raw `web_fetch` calls in briefing pipelines with this skill so
+the agent doesn't re-narrate already-known facts.
+
+## Recency filter
+
+Pass `recency_filter` to Perplexity: `hour | day | week | month`. Useful
+for news-cycle topics; omit for evergreen research.
+
+## Anti-Patterns
+
+- ❌ Sending NO brain context. Then it's just a search — use `web_fetch`
+  instead.
+- ❌ Truncating the brain context. The whole point is "knows what you
+  know." Send dense context.
+- ❌ Discarding citations. Every claim in the output must have a URL.
+- ❌ Skipping the cross-link step when entities are mentioned. Iron Law.
+
+## Environment
+
+- `PERPLEXITY_API_KEY` set in the agent's environment (or in
+  `~/.gbrain/.env`).
+- Optional: install Perplexity's official CLI for richer streaming output.
+
+## Related skills
+
+- `skills/academic-verify/SKILL.md` — wraps perplexity-research for
+  citation-verified academic claim checking
+- `skills/enrich/SKILL.md` — calls perplexity-research as part of the
+  entity-enrichment loop
+- `skills/data-research/SKILL.md` — structured-data trackers (different
+  shape: parameterized YAML recipes, not free-form research)
+
+
+## Contract
+
+This skill guarantees:
+
+- Routing matches the canonical triggers in the frontmatter.
+- Output written under the directories listed in `writes_to:` (when applicable).
+- Conventions referenced (`quality.md`, `brain-first.md`, `_brain-filing-rules.md`) are followed.
+- Privacy contract preserved: no real names, no fork-specific filesystem path literals, no upstream-fork references.
+
+The full behavior contract is documented in the body sections above; this section exists for the conformance test.
+
+## Output Format

+The skill's output shape is documented inline in the body sections above (see "Output", "Brain page format", or equivalent). The literal section header here exists for the conformance test (`test/skills-conformance.test.ts`).

+
+Take a large text PLUS a specific strategic problem, produce analysis that

+(extract → analyze → mirror), different lens.

+specific gatekeeper-vs-incumbent fight, producing a tactical analysis that
+maps the book's playbook onto the situation with counter-tactics and a
+short/medium/long-term playbook.
+
+## Inputs
+
+1. **Source text** — book (EPUB/PDF), article, transcript, historical case
+   study, any large document.
+2. **Strategic problem** — the specific situation to analyze through the
+   lens of the text. The user describes this explicitly or it's obvious
+   from context.
+
+## Output
+
+The brain page is the artifact. PDF is a rendering, never primary.
+
+### Brain page structure
+
+```markdown
+# [Source Title] — Applied to [Problem]
+
+> One-paragraph executive summary: how the source maps to the situation,
+> the key insight, the bottom line.
+
+## The Core Parallel
+How the source's central dynamic maps onto the user's situation.
+
+## Chapter / Section Triage
+For each major section of the source:
+- 2-3 sentence summary of what it says
+- Relevance to the problem: HIGH / MEDIUM / LOW
+- One directly applicable quote (if any)
+
+## The Source's Playbook
+The author's framework, tactics, or strategies — organized as:
+- What the protagonist DID (tactics)
+- What WORKED and why
+- What FAILED and why
+- What OPPONENTS did that was effective
+
+## Counter-Tactics
+Specific moves from the source that map to the user's situation:
+- What to DO (with source evidence)
+- What to AVOID (with source evidence)
+- What to WATCH FOR (warning signs from the source)
+
+## Applied Playbook
+The synthesis — actionable recommendations:
+- **Short-term** (this week / this month)
+- **Medium-term** (this quarter)
+- **Long-term** (this year+)
+
+## Key Quotes
+Direct quotes from the source that are devastatingly relevant.
+Maximum 5-10. Quality over quantity.
+
+## See Also
+Links to relevant brain pages (related concepts, related projects).
+```
+
+## Process
+
+```
+Phase 1: Ingest the source
+  ├── EPUB: extract chapters via BeautifulSoup (see book-mirror SKILL.md
+  │   for the extraction pipeline)
+  ├── PDF: pdftotext -layout
+  ├── Article: web_fetch
+  └── Identify Table of Contents and total size.
+
+Phase 2: Triage chapters
+  ├── Read first 2000 chars of each chapter.
+  ├── Classify relevance to the problem (HIGH / MEDIUM / LOW).
+  └── HIGH chapters get full reads. MEDIUM partial. LOW skipped.
+
+Phase 3: Deep read HIGH chapters
+  ├── Tactics and strategies used.
+  ├── Power dynamics and how they shifted.
+  ├── Specific quotes that map to the problem.
+  └── Moments where the protagonist's approach succeeded or failed.
+
+Phase 4: Synthesize
+  ├── Map source insights onto the specific problem.
+  ├── Build the playbook (do / avoid / watch for).
+  ├── Generate short/medium/long-term recommendations.
+  └── Select the most devastating quotes.
+
+Phase 5: Write and deliver
+  ├── Write the brain page at the right location:
+  │     • If problem-specific: projects/<slug>/playbook.md
+  │     • If general strategy: concepts/<slug>.md
+  ├── put_page via the standard CLI flow.
+  └── Optional: render to PDF via skills/brain-pdf.
+```
+
+## Quality bar
+
+- **Every recommendation must cite the source.** Don't say "go direct to
+  the mayor" — say "go direct to the mayor, because when the protagonist
+  refused to be intimidated by a resignation threat (Ch 48), the bluff
+  that worked on five mayors finally failed."
+- **Direct quotes are mandatory.** The source's own words carry more
+  weight than paraphrase.
+- **The analysis must be actionable.** Not "this is interesting" but "do
+  this, avoid that, watch for this."
+- **Short/medium/long-term breakdown is mandatory.** The user needs to
+  know what to do tomorrow AND what to do this year.
+
+## What this skill is NOT
+
+- Not a book summary tool. Use a different skill (or `book-mirror` for
+  personalized analysis) for general summaries.
+- Not a research tool. Use `perplexity-research` for finding new
+  information about a topic.
+- Not academic literary analysis. No one cares about literary merit —
+  only strategic application.
+
+## Related skills

+- Routing matches the canonical triggers in the frontmatter.
+- Output written under the directories listed in `writes_to:` (when applicable).

-# Testing Skill — Skill Validation Framework
+# Testing Skill — Validation + Daily Health & Regression Intelligence
 
-## Contract
+> **Convention:** see [conventions/quality.md](../conventions/quality.md) for
+> the test-before-bulk pattern; this skill enforces it across the project's
+> own test suite.
 
-This skill guarantees:
-- Every skill directory has a SKILL.md file
-- Every SKILL.md has valid YAML frontmatter (name, description)
-- Every SKILL.md has required sections (Contract, Anti-Patterns, Output Format)
-- manifest.json lists every skill directory
-- RESOLVER.md references every skill in the manifest
+## Two modes
+
+This skill has two related but distinct modes:
+
+1. **Skill conformance validation** — gbrain's own conformance bar
+   (the original 1.0 scope). Validates every skill has SKILL.md with
+   frontmatter, every reference exists, manifest + resolver coverage
+   round-trips.
+
+2. **Project test-suite health (v0.25.1 extension)** — runs the
+   project's tiered test suite and produces a regression-classified
+   report. Used by daily cron, container-restart bootstrap, and
+   "how are the tests" prompts.
+
+Pick the mode by trigger.
+
+## Mode 1: Skill conformance validation
+
+### Contract
+
+This mode guarantees:
+
+- Every skill directory has a `SKILL.md` file
+- Every `SKILL.md` has valid YAML frontmatter (`name`, `description`)
+- Every `SKILL.md` has required sections per
+  `test/skills-conformance.test.ts`
+- `skills/manifest.json` lists every skill directory
+- `skills/RESOLVER.md` references every skill in the manifest
+- `openclaw.plugin.json` `skills[]` round-trips with both
 - No MECE violations (duplicate triggers across skills)
 
-## Phases
+### Phases
 
-1. **Walk skills directory.** List all subdirectories containing SKILL.md.
+1. **Walk skills directory.** List all subdirs containing `SKILL.md`.
 2. **Validate frontmatter.** Parse YAML, check required fields.
-3. **Validate sections.** Check for Contract, Anti-Patterns, Output Format headings.
-4. **Check manifest.** Every skill directory must be listed in manifest.json.
-5. **Check resolver.** Every manifest skill must have a RESOLVER.md entry.
-6. **Report results.**
+3. **Validate sections.** Check for the required headings.
+4. **Check manifest.** Every skill dir must be in `manifest.json`.
+5. **Check resolver.** Every manifest skill must have a RESOLVER row.
+6. **Check round-trip.** RESOLVER trigger ↔ frontmatter triggers.
+7. **Report results.**
 
-Automated: `bun test test/skills-conformance.test.ts test/resolver.test.ts`
+### Automation
 
-## Output Format
+```bash

 ```
 
+## Mode 2: Project test-suite health (v0.25.1)
+
+### When to use
+
+- Daily test cron fires
+- User asks "run the tests" / "how are the tests" / "what's broken"
+- After significant code changes (often via cross-modal-review)
+- After container restart (bootstrap)
+- When something seems off and you want to verify system health
+
+### Test tiers
+
+| Tier | What it runs | Wall time | Gates |
+|------|--------------|-----------|-------|
+| **Unit** | `bun test` (deterministic, zero external calls) | <2s | Every commit |
+| **Evals** | LLM-judge or quality evals | ~60s | Daily |
+| **Integration** | E2E tests against real Postgres | ~5m | Pre-ship + nightly |
+| **System health** | Disk / memory / CPU / service liveness | <10s | Daily |
+
+### Daily run protocol
+
+When the cron fires (or the user asks), do ALL of this:
+
+#### 1. Run unit tests
+
+```bash
+bun test 2>&1
+```
+
+Parse: total passed, total failed, total skipped, file-level results.
+
+#### 2. Run evals (if the project has an evals config)
+
+```bash
+# Adapt to the project's eval config
+bun test --filter eval 2>&1
+```
+
+Parse: same format. Note any flakes (tests that fail due to API
+timeouts, not code bugs).
+
+#### 3. Run system health checks
+
+- Disk / memory / CPU
+- gbrain: `gbrain doctor --fast --json`
+- Database connection (if applicable)
+- Critical files exist (CLAUDE.md, AGENTS.md, etc.)
+
+#### 4. Git diff analysis (CRITICAL — regression intelligence)
+
+```bash
+# What changed since last test run?
+git log --oneline --since="24 hours ago"
+```
+
+For each failing test:
+
+1. Check if the test itself was modified recently (test change, not
+   regression).
+2. Check if the code it tests was modified recently (possible
+   regression).
+3. Check if it's a known flake (API timeout, service down).
+4. Check if a dependency was updated (gbrain, bun, etc.).
+
+#### 5. Classify each failure
+
+| Classification | Marker | Action |
+|---------------|--------|--------|
+| **REGRESSION** — code changed, test broke | 🔴 | Flag with the commit that broke it |
+| **STALE** — test expects old behavior; code is correct | 🟡 | Fix the test, not the code |
+| **FLAKE** — API timeout, service down, LLM variance | ⚠️ | Note, don't alarm; retry once |
+| **NEW** — test was just added and isn't passing yet | 🟢 | Check if intentional |
+| **INFRA** — container restart wiped state | 🛠 | Run bootstrap, retest |
+
+#### 6. Report format
+
+```
+🧪 Daily Tests — YYYY-MM-DD
+
+Unit:   X/Y passed (Z skipped)
+Evals:  X/Y passed
+System: [health summary]
+
+REGRESSIONS:
+  🔴 <test-name>: broke by commit <sha> "<commit message>"
+
+STALE TESTS:
+  🟡 <test-name>: expects X but code now does Y (commit <sha>)
+
+FLAKES:
+  ⚠️ <test-name>: timeout (retry passed)
+
+✅ ALL CLEAR  (when applicable)
+```
+
+#### 7. Auto-fix protocol
+
+**DO auto-fix:**
+
+- Test expects an old file path after a rename → update the test
+- Test expects an old version string → update
+- Test expects a file that was intentionally deleted → remove the test
+- Import path broke because file moved → fix the import
+
+**DO NOT auto-fix:**
+
+- Test expects behavior A but code now does B → ASK first. Maybe the
+  test is right and the code has a bug.
+- Security test failing → ALWAYS escalate, never auto-fix.
+- Test was skipped with a TODO → don't un-skip without understanding why.
+
+When uncertain: check the commit message that changed the code, check
+if there's a related PR or conversation, ask the user if still unclear.
+
+### State (regression history)
+
+Track results in `~/.gbrain/test-state.json` for trend tracking:
+
+```json
+{
+  "lastRun": "2026-04-16T13:37:00Z",
+  "unit": { "passed": 1262, "failed": 31, "skipped": 8 },
+  "evals": { "passed": 17, "failed": 0 },
+  "system": { "doctor": "ok", "gbrain": "0.25.1" },
+  "failureHistory": [
+    { "test": "<name>", "since": "2026-04-14", "classification": "stale" }
+  ]
+}
+```
+
+This enables:
+
+- Trend tracking (are we getting better or worse?)
+- Flake detection (same test fails intermittently)
+- Regression velocity (how fast do we break things after changes?)
+
 ## Anti-Patterns
 
-- Skipping validation after adding a new skill
-- Adding skills to manifest without adding to resolver
-- Creating skills without the conformance template
+- ❌ Skipping conformance validation after adding a new skill
+- ❌ Adding skills to `manifest.json` without adding to RESOLVER.md
+- ❌ Treating every red test as a regression. Classify first; many are
+  stale or flaky.
+- ❌ Auto-un-skipping a test without understanding why it was skipped
+- ❌ Auto-"fixing" a security test failure
+- ❌ Reporting "all clear" without actually running system health checks
+
+
+## Contract
+
+This skill guarantees:
+
+- Routing matches the canonical triggers in the frontmatter.
+- Output written under the directories listed in `writes_to:` (when applicable).
+- Conventions referenced (`quality.md`, `brain-first.md`, `_brain-filing-rules.md`) are followed.
+- Privacy contract preserved: no real names, no fork-specific filesystem path literals, no upstream-fork references.
+
+The full behavior contract is documented in the body sections above; this section exists for the conformance test.
+
+## Output Format
+
+The skill's output shape is documented inline in the body sections above (see "Output", "Brain page format", or equivalent). The literal section header here exists for the conformance test (`test/skills-conformance.test.ts`).

+> **Convention:** see [_brain-filing-rules.md](../_brain-filing-rules.md) for

+
+## Iron Law
+
+The user's **exact words** are the insight. Never paraphrase. Never clean
+up. The vivid, unpolished, stream-of-consciousness phrasing captures
+something that cleaned-up prose does not. Preserve it in block quotes.
+The Analysis section can interpret; the transcript section is sacred.
+
+- ✅ `"The ambition-to-lifespan ratio has never been more fucked"`
+- ❌ `User noted the tension between ambition and mortality`
+
+## When to invoke
+
+The user sends an audio or voice message via any channel (Telegram, voice
+memo upload, openclaw audio attachment). The host agent typically provides
+the transcript text. If not, transcribe via `gbrain transcription` (Groq
+Whisper by default; OpenAI fallback for audio > 25MB segmented via ffmpeg).
+
+## The pipeline
+
+```
+1. STORE       → Upload original audio to gbrain storage backend
+                 (S3 / Supabase Storage / local — pluggable per
+                 src/core/storage.ts).
+2. TRANSCRIBE  → Use the agent-provided transcript verbatim, OR call
+                 gbrain transcription if no transcript was supplied.
+3. ROUTE       → Apply the decision tree (below) to find the right
+                 destination directory.
+4. WRITE       → Create / update the destination brain page; preserve the
+                 verbatim transcript in a block-quoted "User's Words"
+                 section.
+5. CROSS-LINK  → For every entity mentioned (person, company), add a
+                 timeline back-link from THEIR brain page to THIS one
+                 (Iron Law per conventions/quality.md).
+```
+
+## Decision tree (where the content goes)
+
+Apply in order. First match wins. If multiple categories apply, file to
+the primary directory and cross-link to the others.
+
+1. **Original idea, observation, or thesis** — the user is expressing a
+   novel thought, framework, or connection THEY generated.
+   → `originals/<slug>.md`. Use the user's vivid language for the slug.
+
+2. **About a world concept they encountered** — a framework or model
+   someone else created that the user is referencing.
+   → `concepts/<slug>.md`.
+
+3. **About a specific person** — new information, opinion, or observation
+   about someone.
+   → Update `people/<person>.md` timeline.
+
+4. **About a specific company** — new info about a company.
+   → Update `companies/<company>.md` timeline.
+
+5. **A product or business idea** — something that could be built.
+   → `ideas/<slug>.md`.
+
+6. **A personal reflection** — therapy-adjacent, emotional, identity.
+   → Append to appropriate `personal/<slug>.md`.
+
+7. **None of the above / random thought / doesn't fit cleanly** —
+   → `voice-notes/YYYY-MM-DD-<slug>.md` (catch-all).
+
+**Multiple categories?** Create the primary page, then cross-link to all
+others. If the voice note covers a person AND a novel idea, create the
+originals/ page AND update the person's timeline.
+
+## Brain page format
+
+For ALL voice-note-derived pages, include this skeleton:
+
+```markdown
+---

+
+> "Exact transcript, verbatim, preserving every word, hesitation, and verbal
+> tic. This is the primary source material. Do not edit."
+
+🔊 [Audio]([gbrain storage URL or relative path])
+
+## Analysis

+```
+
+Include timestamps when available:
+
+```
+[Source: voice note, <channel>, YYYY-MM-DD HH:MM PT]
+```
+
+## Naming convention
+
+- Audio files: `YYYY-MM-DD-<brief-slug>.<ext>` (e.g.,
+  `2026-04-13-rick-rubin-creative-philosophy.ogg`)
+- Brain pages: match the slug of the destination directory.
+
+## Bulk vs. single
+
+This skill handles ONE voice note at a time. Each is its own ingest cycle.
+No batching.
+
+## Anti-Patterns
+
+- ❌ **Paraphrasing the transcript.** The exact words are the signal.
+- ❌ **Cleaning up hesitations or filler words** ("um", "like", "you
+  know"). The texture matters.
+- ❌ **Creating a page with no entity cross-links** when people/companies
+  were mentioned. Iron Law fail.
+- ❌ **Skipping the audio storage step.** Always upload the original; the
+  brain page has a `🔊 [Audio]` link back to it.

+/**
+ * `gbrain book-mirror` — flagship of the v0.25.1 skills wave.
+ *
+ * Takes pre-extracted chapter text + context, fans out N read-only Opus
+ * subagents (one per chapter), waits for all to complete, assembles the
+ * two-column personalized analysis, and writes ONE put_page under
+ * `media/books/<slug>-personalized.md` using the operator-trust path.
+ *
+ * Trust contract (D2/α + codex HIGH-1 fix):
+ * - Subagents have allowed_tools: ['get_page', 'search'] only — they
+ *   can READ the brain, but they CANNOT call put_page. They produce
+ *   markdown analysis text via their final_message; the CLI reads
+ *   job.result and assembles the final page itself.
+ * - The CLI calls put_page once at the end with operator-level trust
+ *   (no viaSubagent flag), so the subagent namespace check doesn't
+ *   apply. Untrusted EPUB content cannot prompt-inject any people/*
+ *   page because subagents lack write access entirely.
+ *
+ * The skill (skills/book-mirror/SKILL.md) handles EPUB/PDF extraction
+ * via the agent's shell + python access (BeautifulSoup4, pdftotext) and
+ * invokes this CLI with --chapters-dir pointing at the extracted text.
+ * Separation of concerns: skill prepares inputs, CLI is the trusted
+ * runtime.
+ *
+ * Cost: a 20-chapter book at Opus pricing is ~$6/run. The CLI prints an
+ * estimate before launching and prompts for confirmation unless
+ * --no-confirm is passed.

+
+USAGE
+  gbrain book-mirror --chapters-dir <path> --slug <slug> [flags]
+
+REQUIRED
+  --chapters-dir <path>     Directory containing chapter text files (.txt).
+                            Files sort alphabetically; chapter order = sort order.
+                            The skill (skills/book-mirror/SKILL.md) handles EPUB
+                            and PDF extraction; this CLI takes pre-extracted
+                            chapter text as its input contract.
+  --slug <slug>             Brain page slug (kebab-case, no leading slash).
+                            Output lands at media/books/<slug>-personalized.md.
+
+OPTIONAL
+  --context-file <path>     Path to a context pack (USER.md + SOUL.md + memory
+                            excerpts + entity searches). Embedded in every
+                            child subagent's prompt. The skill prepares this.
+  --title "<title>"         Book title (used in the assembled page header).
+                            Defaults to slug if omitted.
+  --author "<author>"       Book author (used in frontmatter + page header).
+  --model <id>              Anthropic model id for chapter analysis.
+                            Default: claude-opus-4-7. Sonnet works but the
+                            right-column quality drops.
+  --max-turns <n>           Per-chapter subagent turn budget. Default ${DEFAULT_MAX_TURNS}.
+  --timeout-ms <n>          Per-chapter wall-clock timeout.
+  --no-confirm / --yes      Skip the cost-estimate confirmation prompt.
+  --no-follow               Submit and exit; don't tail children.
+  --dry-run                 Validate inputs + print plan; submit nothing.
+
+TRUST CONTRACT (read this)
+  Each chapter is analyzed by a separate subagent with allowed_tools
+  restricted to ['get_page', 'search'] — read-only. Subagents return
+  markdown analysis text in their final message. THIS CLI assembles all
+  child outputs and writes one put_page under media/books/<slug>-personalized.md
+  with operator trust. Subagents NEVER call put_page; untrusted book
+  content cannot prompt-inject any people/* page.
+
+  See src/commands/book-mirror.ts top-of-file comment for the full
+  rationale (codex HIGH-1 fix vs the v0.25.1 plan's earlier draft).
+
+COST
+  ~\$${COST_PER_CHAPTER_OPUS.toFixed(2)} per chapter at Opus, ~\$${COST_PER_CHAPTER_SONNET.toFixed(2)} at Sonnet. A 20-chapter book
+  is ~\$${(20 * COST_PER_CHAPTER_OPUS).toFixed(2)} at Opus. The CLI prints an estimate before launching.

+- LEFT column: preserve stories, stats, frameworks. Don't summarize away the texture.
+- RIGHT column: use the user's actual words from READER CONTEXT. Name specific people, dates, situations. Read like a therapist who knows them.
+- 4-10 rows per chapter. If a section honestly doesn't apply, write \`*This section is less directly relevant because [specific reason].*\` Don't force connections.
+- Never generic ("This might apply if you've ever felt..."). Never sycophantic. Never preach.
+- Use \`<br><br>\` for paragraph breaks inside table cells, not literal newlines.
+
+You have ${DEFAULT_MAX_TURNS} turns and read-only tools (get_page, search). You CANNOT call put_page — your output is the markdown text in your final message. The CLI assembles all chapters and writes the brain page.

+ * rejection. Kept in a sibling file because it's a separate concern
+ * (archive scanning, not storage tiering) — adding it to
+ * storage-config.ts would muddy single-responsibility for code that
+ * just happens to share a config file.
+ *
+ * Example gbrain.yml:
+ *
+ *   archive-crawler:

+/**
+ * post-install-advisory.ts (v0.25.1) — agent-readable "what to do next"
+ * after `gbrain init` or `gbrain upgrade`.
+ *
+ * gbrain users typically interact through their host agent (openclaw,
+ * claude-code) rather than the gbrain CLI directly. So an interactive
+ * TTY prompt at install time misses most of the audience.
+ *
+ * Instead: every `init` and `post-upgrade` ends by printing an advisory
+ * that the agent reads from terminal output. The advisory:
+ *
+ *   1. Names the version that just landed.
+ *   2. Lists the new skills that aren't yet installed in this workspace.
+ *   3. Includes a one-line description per skill.
+ *   4. Tells the agent EXPLICITLY: ask the user before installing.
+ *   5. Prints the exact command to run if the user says yes.
+ *
+ * Detection: parse the cumulative-slugs receipt in the workspace's
+ * managed block (RESOLVER.md / AGENTS.md). Any skill in the recommended
+ * set that isn't in the receipt is "not yet installed."
+ *
+ * Recommended set: hardcoded for v0.25.1 (the 9 new skills). Future
+ * releases either bump the constant or read it from the latest
+ * migration file's frontmatter; for v0.25.1 the constant is the simpler
+ * path.
+ *
+ * No-op safely:
+ *   - No workspace detected → no advisory (don't fabricate paths).
+ *   - All recommended skills already installed → no advisory
+ *     (don't nag the agent every command).
+ *   - Pre-v0.19 fence with no receipt → use the row-extracted slug set.

+ * Tests for src/commands/book-mirror.ts — flagship v0.25.1 CLI.
+ *
+ * Pure surface tests. The full subagent-fan-out integration path
+ * needs a live queue engine + ANTHROPIC_API_KEY and is exercised by
+ * the opt-in smoke test (test/e2e/skill-smoke-openclaw.test.ts when
+ * EVALS=1 EVALS_TIER=skills is set).
+ *
+ * Constraint: src/cli.ts dispatches connectEngine() BEFORE any
+ * CLI_ONLY command's own arg parsing, including --help. This is a
+ * pre-existing architectural choice (every CLI_ONLY command —
+ * agent, sync, jobs, book-mirror — behaves the same). So we can't
+ * exercise help-text or arg-validation paths from a clean tempdir
+ * without DATABASE_URL.
+ *
+ * What we DO test:
+ *   - The book-mirror command is registered (CLI dispatches it
+ *     instead of "Unknown command").
+ *   - Without DB, the command fails fast and never reaches the
+ *     queue-submission path.
+ *   - The command source file is parseable + exports the runner.

+/**
+ * cli-pty-runner.ts — generic real-PTY runner for CLI E2E tests.
+ *
+ * Ported from gstack's claude-pty-runner.ts (D14/C-prime in the v0.25.1
+ * plan). Generalized to drive any CLI binary (gbrain, openclaw, claude)
+ * — the gstack-specific plan-mode orchestrators (runPlanSkillObservation,
+ * runPlanSkillCounting, invokeAndObserve, the per-skill Step-0 boundary
+ * predicates) are dropped because they assume Claude Code's plan-mode
+ * UI specifics that don't apply here.
+ *
+ * Architecture: pure Bun.spawn — no node-pty, no native modules. Bun
+ * 1.3.10+ has built-in PTY support via the `terminal:` spawn option.
+ *
+ * What gbrain uses this for in v0.25.1:
+ *   - test/e2e/skill-smoke-openclaw.test.ts: drive an openclaw session
+ *     interactively after `gbrain skillpack install book-mirror`,
+ *     verifying real numbered-menu routing.
+ *   - Future: any CLI command that grows interactive prompts (e.g.,
+ *     book-mirror's cost-estimate "Continue? [y/N]") becomes testable
+ *     without a refactor.
+ *
+ * For non-interactive CLI tests (skillpack install/uninstall stdout
+ * grep), use Bun.spawnSync directly — that's lighter and matches the
+ * existing test/cli.test.ts pattern.

+/**
+ * Tests for src/core/skillpack/installer.ts applyUninstall (D6 + D8 + D11).
+ *
+ * Uses the same scratch-gbrain pattern as test/skillpack-install.test.ts:
+ * a tempdir source bundle (alpha + beta + shared_deps) and a tempdir
+ * target workspace. Install first, then exercise uninstall semantics.
+ *
+ * Coverage:
+ *   - happy path (slug in receipt, files match bundle) — files removed,
+ *     managed block updated, cumulative-slugs receipt loses the slug
+ *   - D8: slug NOT in cumulative-slugs receipt → user_added_slug
+ *   - D11: file content modified → locally_modified (refuse-and-warn)
+ *   - D11: --overwrite-local → removes anyway
+ *   - unknown skill slug → unknown_skill
+ *   - dry-run does not write
+ *   - uninstall of one skill preserves OTHER installed skills' rows
+ *   - lockfile contention with --force-unlock escape hatch
+ *   - idempotent: file already absent on disk doesn't crash
