docs: sync project docs for v0.23.2 marker-based guard

Update CLAUDE.md Key Files entries for src/core/cycle/synthesize.ts,
src/core/cycle/transcript-discovery.ts, and src/commands/dream.ts to
reflect the v0.23.2 dream_generated frontmatter marker that replaces the
v0.23.1 content-prefix self-consumption guard, plus the new
--unsafe-bypass-dream-guard CLI flag.

 - `src/core/sync-concurrency.ts` (v0.22.13) — single source of truth for the parallel-sync policy. Exports `autoConcurrency(engine, fileCount, override?)` (PGLite always serial; explicit override clamped to >=1; auto path returns `DEFAULT_PARALLEL_WORKERS=4` when `fileCount > AUTO_CONCURRENCY_FILE_THRESHOLD=100`), `shouldRunParallel(workers, fileCount, explicit)` (Q1: explicit `--workers` bypasses the >50-file floor), and `parseWorkers(s)` (rejects `'0'`, `'-3'`, `'foo'`, `'1.5'`, trailing chars — replaces the prior parseInt-with-no-validation in both `sync.ts` and `import.ts`). Used by `performSync`, `performFullSync`, `runImport`, and the Minion `sync` handler so the three sites can no longer drift.
 - `src/commands/sync.ts` — `gbrain sync` CLI + the `performSync` / `performFullSync` library entrypoints (consumed by the autopilot cycle and the Minion sync handler). v0.22.13 (PR #490): `performSync` wraps its body in a `gbrain-sync` writer lock so two concurrent syncs (manual + autopilot, two terminals, two Conductor workspaces) cannot both write `last_commit` and let the last writer win. Head-drift gate after the import phase re-checks `git rev-parse HEAD`; if HEAD moved (someone ran `git checkout` / `git pull` mid-sync), the bookmark refuses to advance. Vanished files now record a failedFiles entry instead of silent-skip — the silent-skip-then-advance pathology that survived prior hardening passes is dead. Worker engines wrap in try/finally so disconnect always fires (panic-path leak fix). Both PGLite-detection sites use `engine.kind === 'pglite'`. CLI accepts `--workers N` (alias `--concurrency N`), validated via `parseWorkers`. Explicit `--workers` bypasses the auto-path file-count floor; auto path defers to `autoConcurrency()`. Banner moved to stderr.
 - `src/core/cycle.ts` — v0.17 brain maintenance cycle primitive (extended to **8 phases in v0.23**). `runCycle(engine: BrainEngine | null, opts: CycleOpts): Promise<CycleReport>` composes phases in semantically-driven order: **lint → backlinks → sync → synthesize → extract → patterns → embed → orphans**. v0.23's `synthesize` phase runs after sync (cross-references see fresh brain) and before extract (auto-link materializes its writes); `patterns` runs after extract so it reads a fresh graph (codex finding #7 — subagent put_page sets `ctx.remote=true` and skips auto-link/timeline by default; extract is the canonical materialization). Three callers: `gbrain dream` CLI, `gbrain autopilot` daemon's inline path, and the Minions `autopilot-cycle` handler. Coordination via `gbrain_cycle_locks` DB table + `~/.gbrain/cycle.lock` file lock with PID-liveness for PGLite. `CycleReport.schema_version: "1"` is stable; totals additively grew in v0.23 (`transcripts_processed`, `synth_pages_written`, `patterns_written`). `yieldBetweenPhases` runs between phases. **v0.23 added `yieldDuringPhase`** for in-phase keepalive — synthesize/patterns call it during long waits to renew the cycle-lock TTL. Engine nullable; lock-skip on read-only phase selections. v0.22.1 (#403): `CycleOpts.signal?: AbortSignal` propagates the worker's abort signal; `checkAborted()` fires between every phase. v0.22.1 (#417): `runPhaseSync` returns `pagesAffected` via `SyncPhaseResult`; `runCycle` captures it and threads to `runPhaseExtract` as the 4th arg. v0.22.1 (Codex F2): `runPhaseSync` takes `willRunExtractPhase: boolean` and sets `noExtract: phases.includes('extract')` so `gbrain dream --phase sync` doesn't silently lose extraction. v0.22.5 (#475): `resolveSourceForDir(engine, brainDir)` threads `sourceId` to `performSync()` so sync reads the per-source `sources.last_commit` anchor instead of the drift-prone global `config.sync.last_commit` key.
-- `src/core/cycle/synthesize.ts` (v0.23) — Synthesize phase: conversation-transcript-to-brain pipeline. Reads from `dream.synthesize.session_corpus_dir`, runs cheap Haiku verdict (cached in `dream_verdicts`), then fans out one Sonnet subagent per worth-processing transcript with `allowed_slug_prefixes` (sourced from `skills/_brain-filing-rules.json` `dream_synthesize_paths.globs`). Orchestrator collects slugs from `subagent_tool_executions` (NOT `pages.updated_at` — codex finding #2) and reverse-renders DB → markdown via `serializeMarkdown`. Cooldown via `dream.synthesize.last_completion_ts`, written ONLY on success. Idempotency key `dream:synth:<file_path>:<content_hash>`. Auto-commit deferred to v1.1 (codex #5). `--dry-run` runs Haiku, skips Sonnet (codex #8). Subagent never gets fs-write access.

Auto-commit deferred to v1.1 (codex #5). `--dry-run` runs Haiku, skips Sonnet (codex #8). Subagent never gets fs-write access. **v0.23.2:** `renderPageToMarkdown` (now exported) stamps `dream_generated: true` and `dream_cycle_date` into every reverse-write's frontmatter; `writeSummaryPage` does the same on the dream-cycle summary index. The marker is the explicit identity surface checked by `isDreamOutput` in `transcript-discovery.ts` — replaces the v0.23.1 content-prefix heuristic that could miss real output (`serializeMarkdown` doesn't embed slugs in body) and false-positive on user transcripts citing brain pages. `judgeSignificance` and `JudgeClient` are exported; `judgeSignificance` accepts a `verdictModel` parameter (default `claude-haiku-4-5-20251001`) loaded from `dream.synthesize.verdict_model` via `loadSynthConfig`.
 - `src/core/cycle/patterns.ts` (v0.23) — Patterns phase: cross-session theme detection over reflections within `dream.patterns.lookback_days` (default 30). Names a pattern only when ≥`dream.patterns.min_evidence` (default 3) reflections support it. Single Sonnet subagent; same allow-list path as synthesize. Runs AFTER `extract` so the graph is fresh.
-- `src/core/cycle/transcript-discovery.ts` (v0.23) — Pure filesystem walk for synthesize. `discoverTranscripts(opts)` filters `.txt` files by date range, min_chars, and word-boundary regex `excludePatterns` (Q-3: `medical` matches "medical advice" but NOT "comedical"; power users may pass full regex). `readSingleTranscript(path)` is the `gbrain dream --input <file>` ad-hoc path.
-- `src/commands/dream.ts` — v0.17 `gbrain dream` CLI; ~80-line thin alias over `runCycle`. brainDir resolution requires explicit `--dir` OR `sync.repo_path` config. Flags: `--dry-run`, `--json`, `--phase <name>`, `--pull`, `--dir <path>`. **v0.23 added** `--input <file>` (ad-hoc transcript, implies `--phase synthesize`), `--date YYYY-MM-DD`, `--from <d> --to <d>` (backfill range). Conflict detection: `--input` + `--date` exits 2. ISO date validation. `--dry-run` runs Haiku significance verdict but skips Sonnet synthesis (codex finding #8 — NOT zero LLM calls). Exit code 1 on status=failed.

Both `discoverTranscripts` and `readSingleTranscript` skip matching files and emit a `[dream] skipped <basename>: dream_generated marker` stderr log (no more silent skips). `bypassGuard?: boolean` on `DiscoverOpts` and `readSingleTranscript`'s opts disables the guard for the explicit `--unsafe-bypass-dream-guard` escape hatch only — never auto-applied for `--input`. Replaces v0.23.1's `DREAM_OUTPUT_SLUGS` content-prefix list.
+- `src/commands/dream.ts` — v0.17 `gbrain dream` CLI; ~80-line thin alias over `runCycle`. brainDir resolution requires explicit `--dir` OR `sync.repo_path` config. Flags: `--dry-run`, `--json`, `--phase <name>`, `--pull`, `--dir <path>`. **v0.23 added** `--input <file>` (ad-hoc transcript, implies `--phase synthesize`), `--date YYYY-MM-DD`, `--from <d> --to <d>` (backfill range). Conflict detection: `--input` + `--date` exits 2. ISO date validation. `--dry-run` runs Haiku significance verdict but skips Sonnet synthesis (codex finding #8 — NOT zero LLM calls). Exit code 1 on status=failed. **v0.23.2 added** `--unsafe-bypass-dream-guard` (long-form intentional, plumbed through `runCycle.synthBypassDreamGuard` → `SynthesizePhaseOpts.bypassDreamGuard` → `discoverTranscripts({bypassGuard})` and `readSingleTranscript({bypassGuard})`). Loud stderr warning fires at synthesize-phase entry when set. Never auto-applied for `--input` so any caller can't silently re-trigger the loop bug.
 - `src/commands/friction.ts` + `src/core/friction.ts` (v0.23) — `gbrain friction {log,render,list,summary}` reporter. Append-only JSONL under `$GBRAIN_HOME/friction/<run-id>.jsonl`. Schema is a flat extension of `StructuredAgentError` (D20). Render groups by severity → phase, defaults to `--redact` for md output (strips `$HOME`/`$CWD` to placeholders so reports paste safely in PRs). Run-id resolves from `--run-id` > `$GBRAIN_FRICTION_RUN_ID` > `standalone.jsonl`. Skills the claw-test exercises gain a `_friction-protocol.md` callout so agents know when to log friction.
 - `src/commands/claw-test.ts` + `src/core/claw-test/` (v0.23) — `gbrain claw-test [--scenario <name>] [--live --agent openclaw]`. End-to-end "fresh user" friction harness. Two modes: scripted (CI gate, agent-free) and live (real openclaw subprocess, $1–2 in tokens). Sets `GBRAIN_HOME=<tempdir>` for hermeticity and captures gbrain's `--progress-json` events from each child's stderr to verify expected phases ran (`import.files`, `extract.links_fs`, `doctor.db_checks`). Phases for scripted mode: setup → install_brain (`gbrain init --pglite`) → import (`--no-embed`) → query → extract → verify (`gbrain doctor --json`, asserts `status: 'ok'`) → render. Live mode hands `BRIEF.md` from `test/fixtures/claw-test-scenarios/<name>/` to the agent runner. v1 ships with the OpenClaw runner only (`src/core/claw-test/runners/openclaw.ts`, invokes `openclaw agent --local --agent <name> --message <brief>`); hermes runner deferred to v1.1. Transcript capture (`transcript-capture.ts`) uses `fs.createWriteStream` with `'drain'`-event backpressure — D17 fix for the 256KB-burst child-stall scenario. v0.18 upgrade scenario seeded via `seed-pglite.ts` SQL replay.
 - `skills/_friction-protocol.md` (v0.23) — shared cross-cutting convention skill (like `_brain-filing-rules.md`). Tells agents when to call `gbrain friction log` and how to choose a severity. Routes to friction CLI from any skill the claw-test exercises.
