This is exactly the state the kit's own [succession doctrine](#on-models-after-opus-48) tells you to expect: **keep the cheap deterministic floor** (it costs ~nothing when it never fires — `demo.py` proves it still catches the failure the instant it happens) and **downshift the expensive ceremony first**. The benchmark is the kit's own retirement plan; re-plant a harder trap or fund a larger-n run if you want the probe to discriminate again. -The kit ships its own benchmark (`bench/`): a planted-bug task targeting the documented failure modes, run headless as stock Opus 4.8 vs Opus 4.8 + this kit, scored by a hidden acceptance suite. Headline from [bench/RESULTS.md](bench/RESULTS.md): stock and doctrine-only runs both produced **false "all verified" claims** over a red test suite (the exact failure mode from #63861, reproduced on demand); with the claim-audit gate, **4/4 runs scored 15/15 with zero false claims**, and in one run the transcript shows the gate directly rescuing a would-be false claim — the model tried to stop, got blocked, ran the check it had skipped, and fixed the bug it had shipped. Small n, honest stats in the file. +No spin: on this task and this model, the kit does not raise the score. It is insurance whose trigger has become rare — and the whole design is built so that costs you almost nothing. ## Cross-project memory (fable-mem) Claude Code's native auto-memory is per-git-repo: a decision banked in repo A is invisible while you work in repo B, so the same wheel gets reinvented across projects. fable-mem layers a machine-wide memory corpus **on top of** the native one — never wrapping it, only adding a shared, searchable cross-project surface at `~/.claude/memory/` (unclaimed by any native feature). It carries the same discipline as the rest of the kit: deterministic where it must hold, quiet where it would annoy, fail-open everywhere. -- **Recall without asking.** A UserPromptSubmit hook runs one read-only FTS5 query against a local sqlite index and injects at most three memory pointers (title + one-line description + path — never bodies) as inert, labelled reference data.

Cross-repo, so a lesson from project A surfaces while you work in project B. - **A breadcrumb every session.** A SessionEnd hook appends one NDJSON line (timestamp, cwd, git root + branch + dirty-file count, end reason) to `~/.claude/memory/journal.ndjson` — a deterministic trace even when the session banked nothing — then runs an incremental reindex so this session's memory is searchable in the next. `/memory-review` mines that journal for high-activity sessions that banked nothing and proposes what was worth keeping. - **The promotion boundary is a hook, not a rule.** The one line that must hold is project → global: a work marker (internal ticket id, private hostname, client codename) must never cross into the shared corpus. A PreToolUse guard scans the pending content of any **Write/Edit** into `~/.claude/memory/` against your `privacy.toml` and blocks it (exit 2) before the marker lands; it matches those tools, not Bash/interpreter writes (`cp`/`cat >>`/`python3 -c`), so `mem doctor --privacy` is the detective backstop that sweeps the whole corpus dir — including the `.ndjson` journal — for anything the write-time gate didn't see. - **Hygiene that proposes, never deletes.** `mem gc-scan` mechanically flags near-duplicates, stale entries, relative-date offenders, and same-topic pairs; `/memory-gc` adds three-way contradiction judges and rebuilds the index. Every removal comes back as a proposal — the corpus is never mutated out from under you. -- **Verifiable install.** The doctor scripts check the CLI compiles and report its FTS mode, that the memory dir is writable, and that all three hooks are wired — the same no-silently-inert guarantee the rest of the kit gets. +- **Concurrency-safe & verifiable.** The index upsert is atomic, so two sessions ending at once can't corrupt it; the doctor scripts check the CLI compiles, report its FTS mode, confirm the memory dir is writable, and verify all three hooks are wired — the same no-silently-inert guarantee the rest of the kit gets. -The index is stdlib-only (sqlite3 FTS5, no pip/venv, no daemon or cron) and disposable — rebuilt from the corpus at any time. **Embeddings are a deliberate non-goal for v1**: reach for a vector index only when the corpus exceeds ~500 memories, or when keyword recall demonstrably misses on synonym-heavy queries (the right memory exists but shares no surface tokens with the prompt).
