+**Keeping the deny-list honest against the allow-list's wholesale
+subcommands:** `config/30-permissions.json` wholesale-allows several git
+subcommands (`git branch:*`, `git checkout:*`, `git push:*`, …) because
+requiring per-flag confirmation on every `git status`/`git log`/routine
+`git push` would make the deny-list unusable. That tradeoff only holds if
+the deny-list has an explicit override for every destructive *form* of a
+wholesale-allowed subcommand — otherwise the dangerous form is silently
+auto-approved by the broad allow, with only fail-open safety-net.ts between
+it and the user, contradicting the "deny-list is the boundary" claim above.
+Concretely: `git push -uf`/`-fu` (bundled short flags that still carry
+`-f`, distinct from the literal `--force`/`-f` token forms already denied)
+and `git branch -D`/`-d -f` (force branch delete) each have their own deny
+entry alongside the existing `--force`/`-f`/`-D` forms, mirroring exactly
+what `safety-net.ts`'s `analyzeGitAfterVerb` already treats as must-block.
+When adding a new wholesale-allowed git (or other) subcommand, enumerate its
+destructive forms against safety-net.ts's checks and close the gap in the
+deny-list rather than narrowing the allow — narrowing breaks the common
+case (an interactive human confirming a legitimate `git push --force` to
+their own fork), closing the gap doesn't.

+covered by a `Write`-scoped deny rule. `Edit(~/.claude/settings.json)`,
+`MultiEdit(~/.claude/settings.json)`, and the `.claude.json` equivalents

@@ -226,6 +266,49 @@ What the content manifest does **not** cover:
   worms automate against defaults — but a targeted attacker with full
   user-privilege write access is outside this threat model.
 
+## Scope: the fingerprint and content manifest cover the `hooks` block only
+
+Layers 1 and 2 above (the hooks-block fingerprint and the src content
+manifest) are precisely scoped: `hashHooks()` hashes `settings.hooks` and
+nothing else, and the content manifest verifies script *files*, not other
+`settings.json` keys. Concretely, **`mcpServers`, `permissions`, `env`, and
+every other top-level key of `settings.json` are entirely outside what those
+two layers verify** — a change to any of them, however large, never trips
+the fingerprint mismatch warning, even though `mcpServers` entries run
+arbitrary local commands with full startup (a persistence primitive at
+least as strong as a hook).
+
+Why this boundary, deliberately, rather than widening the hash: `mcpServers`,
+`permissions`, and `env` are all things a user is *expected* to hand-edit
+routinely (adding a personal MCP server, tightening a permission rule,
+setting a project env var) — unlike the `hooks` block, which cc-settings
+owns end-to-end and where any drift from the installed state is inherently
+suspect. Folding those keys into the fingerprint would mean every legitimate
+edit trips the same "tampering" warning as an actual injected payload,
+training users to click through it — the opposite of what a security signal
+is for.
+
+What actually covers `mcpServers`/`env`: layer 3's auditor (above) runs a
+**best-effort pattern-match scan** (`auditEnvAndMcp` in
+`src/lib/audit-hooks.ts`) over `env` values and `mcpServers` command/args
+against the same malware-signature bank used for hooks, reported in its own
+`ENV/MCP SUSPICIOUS` section. This is classification only — it catches an
+*obvious* injected payload (a `curl | sh`, a base64-decode-and-exec, an
+inline `node -e`), the same way the hook auditor's `suspicious` tier does.
+It does **not** give `mcpServers`/`env` the same guarantee `hooks` gets from
+the fingerprint + manifest pair: there's no "this exact value hasn't changed
+since install" check, no content-hash verification of anything an
+`mcpServers.command` points at, and no `trusted` tier — silence means "no
+known signature matched," not "unchanged" or "verified."
+
+**Manual-review guidance:** if you see an `mcpServers` entry or `env` value
+you don't recognize — whether or not the auditor flagged it — treat it the
+same as an unrecognized hook: check whether you or a tool you installed
+added it, and if not, treat it as a compromise signal and follow the
+remediation steps above. `permissions` (the allow/deny lists themselves) has
+no scanner at all yet; review changes to it the same way you'd review any
+other settings.json diff.

+
+## 2. System map (per-area, from full reads)
+
+### Installer & settings composition
+
+The installer is a well-factored TS pipeline: setup.sh/setup.ps1 are thin bootstraps (ensure Bun, delegate to src/setup.ts) with genuine bash/PowerShell parity; composeSettings validates config/ fragments against the Settings zod schema and fails loudly on a bad fragment; all disk writes go through atomicWriteJson/atomicWriteString (tmp+rename); the settings.json merger (settings-merge.ts) is a clean per-key strategy table (permissions union, hooks union with deprecation-prune, env shallow-merge, statusLine reset-on-stale) with real regression-tested logic for the documented "Claude Code reorders hook JSON keys" problem via canonicalKey, and cmdRollback correctly guards against path-traversal/absolute-path tar entries. The light/full profile split is table-driven (PROFILE_MANIFEST) so dry-run/summary/install can't drift from each other. Where it falls short is at the seams between subsystems added in different eras: the code-intel-engine indirection (PR #71, meant to make `tldr`'s backing process swappable) was bolted onto an MCP-merge module whose core invariant — "existing entries in a shared key always win, that's the user's customization" — cannot distinguish cc-settings' own previous write from a genuine user edit, so the engine selection silently stops taking effect after the very first install. Similarly, the light-profile strip logic (which has to reverse-engineer "is this cc-settings-managed" from settings.json content) uses a shallower identity check than the sibling settings-merge.ts module, which already had to fix the same class of bug once. And the backup/cleanOldConfig pairing over-promises: the wipe is broad, the backup is narrow.
+
+### Hot-path hooks & hook runtime
+
+Area covers 10 hot-path hooks (src/hooks/*.ts) plus their shared runtime (hook-runtime.ts, hook-command.ts, hook-config.ts) and supporting libs (quota.ts, review-queue.ts, freeze.ts, status.ts/-types.ts, colors.ts), wired via config/40-hooks.json. Overall the fail-open discipline is genuinely sound and consistently applied: every hook wraps its body in runHook()/try-catch, blockDecision() is the single shared block-grammar, readState/writeState use atomic tmp+rename, and quota.ts validates its cache with zod (RateLimitsCacheSchema/QuotaSteerStateSchema) before trusting it. Quota-steer thresholds (60/85 five-hour, 65/85 seven-day, 10-min stale cutoff, 30-min critical re-remind) match docs/codex-bridge.md exactly. The freeze feature's documented Bash-bypass limitation (skills/freeze/SKILL.md explicitly discloses "shell writes (Bash) are not gated") is transparent, not a hidden gap, so I did not file it. Similarly the "Plan"/"Explore" capitalized entries in review-queue.ts's READ_ONLY_AGENTS turned out to be Claude Code's own built-in SubagentStart matcher names (confirmed via docs/hooks-reference.md's SubagentStart/SubagentStop matcher table) coexisting with this repo's lowercase custom agents — not a bug, and I discarded my initial suspicion after checking. Config/40-hooks.json wiring is largely coherent with what each hook's code expects (matchers align with the fields each hook reads), with one exception noted below. The most consequential surviving finding is in the statusline hot path, where two of four parallel git spawns bypass the codebase's own git-timeout convention (lib/git.ts's runGit/runProcessFull always pass `timeout` + SIGKILL) and could hang the per-turn statusline refresh indefinitely, directly undercutting the file's own "never a blank line" hardening claim.
+
+### One-shot scripts
+
+Read all 34 files in src/scripts/ plus the 8 assigned src/lib/ modules. Overall the one-shot-script layer is competently built: process spawns are timeout-bounded (git.ts, tsc.ts), JSON state is schema-validated on read (checkpoint.ts, knowledge-index.ts), atomic-rename is used correctly for "latest" symlinks (artifact-store.ts), and several scripts show real care about a specific footgun — explicit `Number.isNaN(...)` guards against `parseInt(x) || default` silently reviving a default when the user explicitly passed "0" (checkpoint.ts cmdClean, handoff.ts cmdClean, prune-mcp-auth-cache.ts). That same care is inconsistently applied, though, and the inconsistency is where most defects live: checkpoint.ts's artifact store is scoped per-project and collision-avoids same-second saves; handoff.ts (structurally the same "timestamped artifact + latest symlink" pattern, built on the same artifact-store.ts helpers) is NOT project-scoped at all, contradicting its own skill doc's example filenames. Several scripts are hooks with fail-open contracts that are honored correctly (check-docs-before-install.ts, notify.ts, post-failure.ts, stop-summary.ts all swallow errors as documented). The main gaps found are: cross-project state bleed in the handoff store, the automatic (hook-driven) handoff path never actually populating the content it promises, a dead-on-arrival regex in check-docs-before-install.ts, proof.ts discarding the one thing you need on failure (gate output), and one repeat of the falsy-zero parsing bug in log-bash.ts that the codebase explicitly guards against everywhere else. Exit-code behavior is also inconsistent between the two sibling CLIs (checkpoint.ts vs handoff.ts) for the same "unknown subcommand" case, which is exactly the kind of thing an agent parsing exit codes would misread as success.
+
+### Supply-chain defense & command-execution surfaces
+
+Read all 11 assigned files in full plus config/40-hooks.json, hook-runtime.ts, and grepped for DEPRECATED_COMMAND_PATTERNS/TOOL_INPUT_command to verify cross-file claims. The three-layer supply-chain defense (hooks fingerprint, src content manifest, engine pin) is internally coherent and its SessionStart hook is genuinely fail-open (each check independently try/caught). The hook auditor's classification logic (trusted/unknown/stale/suspicious) is sound: it correctly requires content-hash verification (not path-shape) for "trusted", checks malware signatures unconditionally first, and the compound-command classifier correctly uses `.every()` (not `.some()`) so a `managed || evil` chain can't launder to trusted. safety-net.ts's rm/git/checkout parsers are well-reasoned with documented residual gaps (quoted executables) that SECURITY.md explicitly scopes as advisory-only. Codex bridge (codex.ts, codex-run.ts) uses array-form Bun.spawn with `--` to end option parsing, avoiding shell-injection into the prompt — solid. However, three real gaps surfaced: (1) the fingerprint's hash scope is `settings.json`'s `hooks` key only — sibling keys like `mcpServers` (arbitrary command execution on every session, a stronger persistence primitive than a hook) or `permissions` are entirely outside all three integrity checks, and SECURITY.md's "what we don't cover" list never names this; (2) config/30-permissions.json wholesale-allows several git subcommands whose dangerous sub-forms have no deny-list counterpart, while safety-net.ts (documented as advisory/fail-open, NOT the enforcement boundary per SECURITY.md itself) is the only thing standing between the user and running them; (3) log-bash.ts logs every Bash command (not just blocked ones) through a weaker redaction function than safety-net's, missing GitHub/AWS token and password= patterns entirely.
+
+### Schemas, linters & upstream scanner
+
+Scope: src/schemas/* (10 zod files), schemas/*.schema.json (generated), the 6 lint-*.ts linters, frontmatter.ts/frontmatter-validate.ts, and src/upstream/scan.ts + version-delta.ts/engine-pin.ts/code-intel-engine.ts. Verified `bun run schemas:emit && git diff schemas/` produces zero diff — the generated JSON Schemas are currently fresh against the zod sources, and `bun run src/upstream/scan.ts` executes cleanly end to end (all `.value`/`.unwrap().value` ZodLiteral accessors work as documented). The loose-vs-strict policy is applied consistently and is well-reasoned: files Claude Code itself writes (ClaudeJson, Settings) are `z.looseObject` for forward-compat, with a dedicated top-level-key-only typo guard in tests/schemas.test.ts; agent/skill/profile frontmatter are also loose by design for ecosystem velocity, with install-time (non-fatal) and CI (fatal) validation layered via frontmatter-validate.ts and the individual lint-*.ts scripts respectively. The MCP and Skill "shape guard" pattern (reject cross-shape key mixing before the union strips anything) is a genuinely sound design that correctly catches the stdio/http mixing and command/mcp mixing cases I traced by hand. Running the upstream scanner live surfaced real, current drift it is designed to catch (schema has `advisorModel`, manifest doesn't) — proving the tool works for its stated purpose, but also proving that purpose is narrower than the name suggests: it only ever diffs two hand-maintained local artifacts against each other (manifest.json vs zod schemas) plus an npm version number: it has no path to detect a genuinely new upstream Claude Code feature that a human hasn't yet transcribed into either file, and the CI job for it is explicitly dry-run/non-blocking so this class of drift can persist indefinitely. The main defect cluster is at the loose-object boundary and doc/schema/linter parity: AgentFrontmatter is missing three fields (`skills`, `background`, `allowedTools`) that are actively documented as agent capabilities elsewhere in the repo, so typos in those fields get zero protection despite frontmatter-validate.ts's docstring explicitly promising typo protection; the security-motivated angle-bracket scan exists only for skills, not agents/profiles, despite the same "injected into system prompt" rationale; and kebab-case name validation is implemented with three subtly different regexes across schemas/linters with no shared constant.
+
+### Skill library
+
+Read all 37 skill directories in full (skills/README.md is documentation, not a skill; skills/nuclear-review/references/ is an opt-in example script). The library is disciplined overall: `bun run lint:skills` passes clean (0 errors/warnings); `ACTIVE_SKILLS` in src/lib/managed-skills.ts matches skills/ on disk exactly (37=37); MANUAL.md's "All Skills" table also matches disk exactly (37=37, including the newly added `harvest`); every `bun run X` command a skill tells the model to run exists in package.json; every `~/.claude/src/scripts/*.ts` path referenced (checkpoint.ts, freeze.ts, handoff.ts, codex-run.ts, new-skill.ts, review-batch.ts, proof.ts) exists with matching subcommands; every `agent:` frontmatter reference (explore, planner, reviewer, tester, maestro) points to a real agents/*.md file; cross-references between skills (context-doc↔explore↔test via DOMAIN-AWARENESS.md, fix↔ship, refactor↔implementer, qa↔verify, nuclear-review↔adversarial-audit↔zero-tech-debt) are current and explicit, and I found no live skill referencing a retired/merged skill by its old slash-command name — every hit on a tombstoned name (`/context`, `/init`, `/lenis`, `/prd`, `/docs`) is a deliberate "formerly X" or "NOT the same as native X" disambiguation, not stale routing. Trigger-phrase space is also well-managed: near-neighbor pairs (fix/verify, review/nuclear-review/adversarial-audit, checkpoint/handoff, refactor/zero-tech-debt) each carry an explicit "use X instead when Y" line. The true current skill count is 37, confirmed three independent ways (disk, ACTIVE_SKILLS, MANUAL.md table). The defects that do survive are concentrated in two spots: agent/tool-capability mismatches where a skill's documented workflow needs a tool its bound agent or its own `allowed-tools` frontmatter doesn't grant, and doc-count drift around the skill total itself (ironic given the library's own doctrine about drift).
+
+### Agent, profile & rule definitions
+
+Area covers agents/ (10 role agents), profiles/ (6 stack profiles), rules/ (10 path-conditioned rule files + README). Most frontmatter is internally sound: tool lists pass the schema's loose-string validation (src/schemas/agent.ts accepts any string for `tools`), effort/permissionMode values are all legal enum members, and CLAUDE-FULL.md's delegation prose correctly names real agents (explore, planner, implementer, reviewer, tester, scaffolder, deslopper, security-reviewer, maestro, codex-verifier). Profile skills/agent references (build, component, hook, lighthouse, qa, orchestrate) all resolve to real skills. Where the area breaks down is at the seams between docs and the frontmatter they describe: docs/frontmatter-reference.md's own "All Agents in cc-settings" table hasn't been updated for the Sonnet-5 downshift that agents/implementer.md, agents/reviewer.md, and docs/agent-models.md already reflect; docs/agent-models.md documents a model pin for an `oracle` agent that has no agents/oracle.md file (oracle is actually a skill routed to `explore`/sonnet); and the isolation:worktree feature has a documented gotcha (fresh worktrees branch off origin/<default-branch>, losing uncommitted/unpushed work) that reviewer.md and security-reviewer.md walk straight into via their own initialPrompt without applying the documented mitigation. A schema/docs split also exists on `isolation`: the schema enum accepts only `worktree`/`remote`, but the mitigation docs tell users to set `isolation: "head"`, which fails frontmatter validation. Team-mode workflows in deslopper.md and maestro.md also reference tool calls (TeamDelete; the whole Team/Task toolset) absent from those agents' own `tools:` arrays.
+
+### Top-level docs vs reality
+
+Top-level docs are mostly internally consistent — the skill count (37), agent count (10), package.json scripts, plugin manifest, setup.ts CLI flags (--rollback/--dry-run/--light/--interactive/--migrate-only), env vars (CC_MAX_UNREVIEWED, CC_PARALLELMAX_THRESHOLD, CLAUDE_LOG_RETENTION_DAYS, CC_CODE_INTEL_ENGINE), and the AGENTS.md/CLAUDE-FULL.md/CLAUDE.md three-file split all check out against the actual repo state. The 29-events/8-categories hooks taxonomy claim in CLAUDE-FULL.md and docs/hooks-reference.md is arithmetically correct. Where it breaks down is in a handful of concrete, checkable claims that have drifted from the code they describe: an MCP server (Sanity) documented as auto-installed 'core' infrastructure that the actual composition file never includes; a model-routing table that names an agent that doesn't exist (oracle) while omitting one that does (codex-verifier); a 'Guardrails (Always Active) — enforced automatically' claim that overstates what the pre-commit hook actually runs; the canonical hooks reference missing four real, active hooks; and a stale skill count in README.md that the same repo gets right in three other files. None of these are subtle style nitpicks — each is a claim a reader would act on (install expectations, hook debugging, commit safety, model cost) that the code contradicts.
+
+### Test suite as a truth surface
+
+Read all 52 files under tests/ (42 .test.ts files + fixtures/ + one orphaned .sh). Overall the bun:test suite is unusually rigorous for a config-installer repo: pure-function libs (quota.ts, codex.ts, review-queue.ts, version-delta.ts, settings-merge.ts strategies) get exhaustive positive/negative/boundary cases; hooks that gate destructive actions (safety-net.ts, tool-cadence.ts, freeze-guard.ts) get real adversarial-bypass regression tests with concrete attacker payloads; the installer/merger gets golden-fixture snapshots (tests/fixtures/migrations/) plus full E2E spawns of `bun src/setup.ts` against a sandboxed HOME; and a blanket hook-fail-open.test.ts spawns every wired hook with garbage stdin/env to guarantee fail-open. Sandbox hygiene (mkdtemp + rm in finally) is consistent throughout, and CI (.github/workflows/ci.yml) actually runs `bun test` across 3 OSes plus dedicated typecheck/lint/schemas/install-e2e/bootstrap jobs. Within that generally sound picture, the weak points cluster in three places: (1) a repo-root drift-detection script that lives in tests/ but is wired into nothing, (2) two PreToolUse/UserPromptSubmit hooks with real, non-trivial branching logic that get only the blanket fail-open smoke test and no behavioral positive/negative cases (unlike their sibling hooks), and (3) one test whose title contradicts its own assertion. None of these break the installer today, but they represent exactly the "truth surface" gaps the audit asks about: places where a green CI checkmark doesn't mean what a reader would assume it means.
+
+### Expectation gaps (expected X, found Y)
+
+- Expected `--rollback` to undo whatever a failed install broke; found it restores 4 files while the pre-copy wipe empties six managed directories (H7).
+- Expected `CC_CODE_INTEL_ENGINE` to switch the tldr engine on re-install; found the merge discards the change after the first install, in two different files, in two different ways (H8, H9).
+- Expected the supply-chain fingerprint to cover the attack surface SECURITY.md describes; found it hashes only the hooks block — env, permissions, and mcpServers are silently out of scope (H12).
+- Expected skills to be executable as written; found three whose mandatory steps require tools their bound agent or allowed-tools list excludes (H13, H14, M-tier deslopper).
+- Expected the automatic PreCompact/SessionEnd handoff to save what the skill's "What Gets Saved" list promises; found hook-driven invocations write near-empty stubs (H10).
+- Expected docs tables (hooks reference, model routing, skill counts) to match the artifacts they describe; found systematic hand-maintained drift (H1, H5, M-tier ×8).

+## 3. Findings by hunt category
+
+### Correctness
+
+#### H3 (high) — reviewer agent's isolation:worktree makes its own diff-review initialPrompt see nothing
+
+- **Location:** `agents/reviewer.md:20-23`
+- **Status:** CONFIRMED · Verifier: Verified agents/reviewer.md:20 sets isolation: worktree and its initialPrompt (line 22-23) literally runs `git diff origin/main...HEAD --stat` / `git diff origin/main...HEAD`, falling back to `git diff HEAD~1`. docs/feature-agents-guide.md:359-368 ('Base ref overwrites in-session edits') explicitly 
+- **Issue:** reviewer.md sets isolation: worktree and its initialPrompt diffs origin/main...HEAD to scope the review, but per docs/feature-agents-guide.md's own documented gotcha, isolation:worktree branches fresh off origin/<default-branch>, so the new worktree's HEAD equals origin/main and never contains the calling session's uncommitted or unpushed changes.
+- **Scenario:** User is on branch feat/x with uncommitted edits (or unpushed local commits) and says "review my changes." reviewer's isolation:worktree spins up a worktree branched from origin/main (baseRef=fresh per docs/settings-reference.md:293), not feat/x. `git diff origin/main...HEAD --stat` (line 23) returns nothing there; the fallback `git diff HEAD~1` shows unrelated history. reviewer still emits "Approved: Yes/No" as if it inspected the real diff.
+- **Recommended direction:** Either drop isolation:worktree from reviewer.md (it's read-only, no write-back risk to justify isolation) or add the documented mitigation to its initialPrompt: commit/stash first, or explicitly base the worktree off current HEAD.
+
+#### H4 (high) — security-reviewer has the same isolation:worktree diff-blindness ahead of merge/deploy gates
+
+- **Location:** `agents/security-reviewer.md:19-22`
+- **Status:** CONFIRMED · Verifier: Verified agents/security-reviewer.md:19 sets isolation: worktree and initialPrompt:21-22 runs secret/pattern greps and `bun audit` before the user's review — same unmitigated worktree-branches-from-origin/main gotcha as reviewer.md, on an agent explicitly meant to gate 'before deploying to productio
+- **Issue:** security-reviewer.md carries isolation:worktree plus an initialPrompt of automated secret/pattern scans, with the same fresh-origin/main worktree blind spot as reviewer.md.
+- **Scenario:** "Before deploying to production or merging sensitive changes" (its own DELEGATE trigger) is exactly when this bites: the agent's automated grep scans (AKIA/sk-/eval/dangerouslySetInnerHTML) run over the pre-existing origin/main tree rather than the user's actual uncommitted/unpushed change, and a real vulnerability in that unpushed diff sails through with "Security Approved: Yes."
+- **Recommended direction:** Same fix as reviewer.md: remove isolation:worktree or have the initialPrompt commit/stash the target changes (or pass isolation:head) before scanning.
+
+#### H6 (high) — Two of four parallel git spawns in the statusline hot path have no timeout
+
+- **Location:** `src/hooks/statusline.ts:64-79`
+- **Status:** CONFIRMED · Verifier: Read src/hooks/statusline.ts:64-79 directly. buildGitStatus() runs Promise.all with four entries: two go through runGit() (src/lib/git.ts:20-32), which Bun.spawn's with `timeout: GIT_TIMEOUT_MS` (15_000ms) and `killSignal: "SIGKILL"`. The other two (lines 66-73) are raw `Bun.spawn(["git", ...], { st
+- **Issue:** buildGitStatus() runs four git operations via Promise.all. Two go through lib/git.ts's runGit() wrapper, which always sets `timeout: GIT_TIMEOUT_MS` (15s) and `killSignal: "SIGKILL"`. The other two — the two `git diff --quiet` / `git diff --cached --quiet` dirty checks — are raw `Bun.spawn([...], { stdout: "ignore", stderr: "ignore" })` calls with NO timeout option at all, unlike every other git spawn in the codebase.
+- **Scenario:** A repo with a hung `git diff --quiet` (stale index.lock, a slow/hanging textconv or diff filter configured in .gitattributes, a network-mounted working tree that blocks on stat/read) never resolves its Promise. `Promise.all([...])` in buildGitStatus never settles, so main() never reaches the final `process.stdout.write`, and the top-level try/catch (which only catches synchronous throws / rejected promises, not indefinite hangs) never fires either. The statusline — advertised in the file's own header comment as hardened to "never print a blank line" — instead prints nothing and blocks the whole per-turn statusline refresh indefinitely, contradicting the stated p95 <100ms budget and the "never blank" guarantee.
+- **Recommended direction:** Route both `diff --quiet` checks through the existing runGit()/runProcessFull() wrappers (or add an explicit `timeout`+`killSignal: "SIGKILL"` to the raw Bun.spawn calls) so every git subprocess in the hot path is bounded the same way.

+#### H8 (high) — Code-intel engine swap never reaches ~/.claude.json after the first install
+
+- **Location:** `src/lib/mcp.ts:148-152 (installMcpToClaudeJson), src/setup.ts:501-515 (installSettings)`
+- **Status:** CONFIRMED · Verifier: Traced end-to-end. src/setup.ts:501-507 clones fullComposed.mcpServers into `teamMcp` and mutates ONLY teamMcp.tldr.{command,args,serverInstructions} to engine.mcp.*. That mutated `teamMcp` is passed to installMcpToClaudeJson(teamMcp) at setup.ts:515. Inside mcp.ts:110-153, `mergedMcp = { ...teamMcp
+- **Issue:** installMcpToClaudeJson computes `mergedMcp = { ...teamMcp, ...currentMcp }` — i.e. whatever is already in ~/.claude.json for a given server name always wins over the freshly-resolved teamMcp entry for that same key. This 'user wins on shared key' rule is exactly the semantics the resolveEngine/CC_CODE_INTEL_ENGINE indirection needs to override on an engine change, but the merge has no way to tell 'the user hand-edited this' apart from 'cc-settings itself wrote this on a previous install with a different engine'.
+- **Scenario:** Fresh install with default engine writes ~/.claude.json's mcpServers.tldr = {command: "tldr-mcp", args: ["--project","."]}. User later runs `CC_CODE_INTEL_ENGINE=native-ts bash setup.sh` to switch engines. setup.ts correctly mutates the in-memory teamMcp.tldr to {command:"bun", args:[nativeMcpServerPath]}, but installMcpToClaudeJson reads the existing tldr entry from disk as `currentMcp.tldr` and it wins the spread — the file is rewritten with the SAME stale {command:"tldr-mcp",...} entry. The engine never actually changes on any install after the first; tests/mcp.test.ts explicitly asserts this precedence ('User override wins for shared key') as intended design, confirming the mechanism is load-bearing and unfixed.
+- **Recommended direction:** Track which mcpServers keys were last written BY cc-settings (e.g. via the existing _status annotation or a per-key hash) so installMcpToClaudeJson can distinguish 'stale cc-settings output' from 'genuine user edit' and let a resolved engine change overwrite the former.
+
+#### M9 (medium) — Array-valued top-level settings defaults can never reach an existing install (nested-default gap recurs for arrays)
+
+- **Location:** `src/lib/settings-merge.ts:410-441 (deepMergeUserWins), config/10-core.json:32-58 (spinnerVerbs.verbs)`
+- **Status:** CONFIRMED · Verifier: Verified src/lib/settings-merge.ts:410-441. deepMergeUserWins recurses only when both sides are plain objects (line 419); for arrays it hits `tIsScalar = !(Array.isArray(team) \|\| ...)` (line 431) which is false for an array, so `!tIsScalar \|\| !uIsScalar` is true and it returns `user` wholesale (line
+- **Team knowledge:** cc-settings-installer-skips-nested-config-defaults (team-knowledge): documents this exact merger class-of-bug for nested object sub-keys; this finding extends it to arrays. The note already prescribes the deep-merge fix.
+- **Issue:** deepMergeUserWins recurses into plain objects so a team-only sub-key can land inside an existing block (the fix for the documented 'installer-nested-default-gap'), but for any key whose value is an array on both sides it immediately does `if (!tIsScalar || !uIsScalar) return user` — the user's whole array wins, with no per-element reconciliation. Because a fresh install writes the team's full default object into settings.json verbatim, every user's on-disk copy of an array default (e.g. spinnerVerbs.verbs) is indistinguishable from a deliberately-customized array.
+- **Scenario:** cc-settings ships a new spinner verb (adds "Pondering" to config/10-core.json's spinnerVerbs.verbs). Every existing install's settings.json already has spinnerVerbs.verbs from a prior install (byte-identical to the OLD team default, never touched by the user) — deepMergeUserWins treats that as a scalar-shape array conflict and keeps the user's (stale) array wholesale. The new default never reaches any pre-existing install, silently, with no log line (only object-shaped new-default landings are counted via `defaultsAdded`).
+- **Recommended direction:** For arrays under the default strategy, at minimum detect 'user array is identical to the OLD team array on file' (impossible without storing a previous-team snapshot) or special-case known array defaults into STRATEGIES like permissions.*, with an explicit team-adds-and-user-can-decline union instead of silent whole-array user-wins.
+
+#### M17 (medium) — check-docs-before-install.ts's INSTALL regex can never match the short forms it explicitly lists
+
+- **Location:** `src/scripts/check-docs-before-install.ts:13`
+- **Status:** CONFIRMED · Verifier: Reproduced empirically: ran the exact regex `/(bun add\|npm install\|npx add\|pnpm add\|bun i \|npm i )\s/` against real inputs. `INSTALL.test("bun i react")` → false, `INSTALL.test("npm i lodash")` → false, while `INSTALL.test("bun i  react")` (two spaces) → true and the long forms (`bun add react`) → t
+- **Issue:** `const INSTALL = /(bun add|npm install|npx add|pnpm add|bun i |npm i )\s/;` — the `bun i ` / `npm i ` alternatives already include the trailing space, and the regex then requires ANOTHER `\s` immediately after the alternation group. For any single-space invocation (the normal case) there is no second whitespace character left to match, so the whole regex fails.
+- **Scenario:** Verified directly: `INSTALL.test("bun i react")` → false, `INSTALL.test("npm i lodash")` → false, while `INSTALL.test("bun i  react")` (two spaces) → true. Since real commands never have two spaces there, the "did you fetch docs first?" reminder never fires for the exact shorthand (`bun i`, `npm i`) the code claims to cover — only the long forms (`bun add`, `npm install`) actually trigger it.
+- **Recommended direction:** Drop the trailing space from the `bun i`/`npm i` alternatives (match `bun i|npm i`) so the outer `\s` supplies the single separator, matching the long-form alternatives' shape.
+
+#### M18 (medium) — checkpoint.ts exits 0 on an unrecognized subcommand; sibling handoff.ts exits 1 for the identical case
+
+- **Location:** `src/scripts/checkpoint.ts:428-446 (default: usage(); — no process.exit) vs src/scripts/handoff.ts:254-276 (default: … process.exit(1))`
+- **Status:** CONFIRMED · Verifier: Directly traced: checkpoint.ts's switch (428-446 as cited, actually lines 428-446 in the read — confirmed at lines 428/444-446) has `default: usage();` with no `process.exit` call, falling through to end-of-script and exiting 0 (Bun's default). handoff.ts's switch (253-276) has an equivalent `defaul
+- **Issue:** checkpoint.ts's command switch has `default: usage();` with no exit call, so a mistyped/unknown subcommand falls through to the end of the script and exits 0 (bun's default success code) — identical to a genuinely successful `save`/`list`/`clean`. handoff.ts's equivalent `default` branch explicitly logs "Unknown command" and calls `process.exit(1)`.
+- **Scenario:** An agent or wrapper script invokes `bun checkpoint.ts restroe latest` (typo). It prints usage text and exits 0. Any caller that gates on exit code (rather than parsing stdout) concludes the restore succeeded when nothing happened at all.
+- **Recommended direction:** Make checkpoint.ts's default branch call `process.exit(1)` after `usage()`, matching handoff.ts's contract.
+
+#### M19 (medium) — log-bash.ts repeats the exact falsy-zero parseInt bug the codebase documents and avoids everywhere else
+
+- **Location:** `src/scripts/log-bash.ts:15`
+- **Status:** CONFIRMED · Verifier: Directly traced log-bash.ts:15: `Number.parseInt(process.env.CLAUDE_LOG_RETENTION_DAYS ?? "1", 10) \|\| 1`. With `CLAUDE_LOG_RETENTION_DAYS=0`, `Number.parseInt("0", 10)` is `0`, and `0 \|\| 1` evaluates to `1` (falsy-zero coercion), silently overriding the explicit 0 back to the default. Confirmed the 
+- **Issue:** `const RETENTION = Number.parseInt(process.env.CLAUDE_LOG_RETENTION_DAYS ?? "1", 10) || 1;` — an explicit `CLAUDE_LOG_RETENTION_DAYS=0` parses to `0`, and `0 || 1` evaluates to `1`, silently overriding the user's explicit "0" back to the 1-day default. Three sibling files in the SAME area (checkpoint.ts cmdClean, handoff.ts cmdClean, prune-mcp-auth-cache.ts) explicitly call out and guard against this exact pattern with `Number.isNaN(parsed) ? default : parsed`, but log-bash.ts was not updated to match.
+- **Scenario:** A user sets `CLAUDE_LOG_RETENTION_DAYS=0` intending to prune same-day bash logs aggressively (e.g. for a shared/CI machine); `pruneOldLogs()` instead keeps a full day of logs because RETENTION silently becomes 1.
+- **Recommended direction:** Replace with the `Number.isNaN`-guarded pattern already used in checkpoint.ts/handoff.ts/prune-mcp-auth-cache.ts.
+
+#### L6 (low) — tool-cadence's file-tracking cap keeps the FIRST 20 files, not the most recent
+
+- **Location:** `src/hooks/tool-cadence.ts:164`
+- **Status:** CONFIRMED · Verifier: src/hooks/tool-cadence.ts:164: `state.files = [...state.files, fp].slice(0, 20)` appends then slices from index 0, so once the array reaches 20 entries, every later distinct file is appended past index 19 and immediately discarded — the tracked set is pinned to the first 20 files ever seen in the st
+- **Issue:** `state.files = [...state.files, fp].slice(0, 20)` appends the new file at the end then slices indices 0-19 — once `state.files.length` reaches 20, every subsequently-edited distinct file is appended past index 19 and immediately discarded by the slice, so the tracked file set freezes permanently for the rest of the streak. This is the opposite of promote-memory.ts's own cap (`seen.slice(-SEEN_SET_CAP)`, correctly keeping the most recent N), even though promote-memory.ts's comment cites tool-cadence's pattern as the model being mirrored.
+- **Scenario:** In an unusually long streak (bulk edit across 20+ distinct files with no Agent call), the escalation check `state.files.length - state.filesAtNudge >= 2` can never trigger via the files dimension once the 20-file cap is hit, because `state.files.length` is pinned at 20 forever after — the exact scenario (mass multi-file edits without delegation) tool-cadence exists to catch. Practically bounded: FILES_THRESHOLD=3 usually fires the initial nudge long before 20 files are touched, so escalation still has the `count` dimension as a backstop, but the files-based escalation signal is silently dead past 20 files.
+- **Recommended direction:** Use `.slice(-20)` (keep most recent 20) to match the rolling-window intent, consistent with promote-memory.ts's own cap.

+### Alternative / unintended paths
+
+#### L11 (low) — checkpoint.ts cmdClean: one entry's stat failure wipes the whole listing and misreports "0 checkpoints"
+
+- **Location:** `src/scripts/checkpoint.ts:372-389`
+- **Status:** CONFIRMED · Verifier: Directly traced checkpoint.ts cmdClean (364-409): `entries = names.map(e => ({file, mtime: lstatSync(full).mtimeMs})).sort(...)` is wrapped in one try/catch (374-383) that resets `entries = []` on ANY error, not per-entry. A single lstatSync ENOENT (e.g. file deleted between listArtifacts' readdir a
+- **Issue:** `entries = names.map(e => ({file, mtime: lstatSync(full).mtimeMs})).sort(...)` is wrapped in a single try/catch that sets `entries = []` on ANY thrown error (e.g. ENOENT from a file deleted between the `listArtifacts` readdir and the synchronous `lstatSync`). A single transient failure on one file discards the entire already-enumerated list, not just the offending entry.
+- **Scenario:** Two concurrent `checkpoint.ts clean` invocations (e.g. two subagents cleaning up in the same project), or a `clean` racing a `save`/another `clean`'s unlink: one file vanishes mid-scan, `lstatSync` throws, `entries` becomes `[]`, and the tool prints "Nothing to clean. 0 checkpoints (keep: N)" even though N+ checkpoints genuinely exist on disk — a misleading status for something that could be read programmatically as "no checkpoints saved".
+- **Recommended direction:** Catch per-entry (skip files that fail to stat) instead of wrapping the whole map/sort in one try/catch, so one race doesn't erase the rest of a valid listing.
+
+### Incoherences
+
+#### H1 (high) — agent-models.md pins a model for an 'oracle' agent that doesn't exist as an agent file
+
+- **Location:** `docs/agent-models.md:19 vs skills/oracle/SKILL.md:6`
+- **Status:** CONFIRMED · Verifier: Verified no agents/oracle.md exists (ls agents \| grep oracle returns nothing) despite docs/agent-models.md:19 listing a dedicated 'oracle' row pinned to opus[1m] with rationale 'Expert Q&A needs nuance.' skills/oracle/SKILL.md:5 sets `agent: explore`, and agents/explore.md:3 pins `model: sonnet`. So
+- **Issue:** The routing table lists a dedicated `oracle` agent pinned to opus[1m] ("Expert Q&A needs nuance"), but there is no agents/oracle.md — skills/oracle/SKILL.md sets `agent: explore`, so oracle invocations actually always run as `explore`, pinned to sonnet. (Also surfaced independently by the docs reader, which adds: the table omits the real codex-verifier agent entirely.)
+- **Scenario:** A user reads "the top tier (opus[1m]) stays on ... the agents whose output is a judgment (orchestration, planning, ... oracle)" and expects `/oracle` to run at Opus quality/cost. In reality skills/oracle/SKILL.md:6 routes to `agent: explore`, and agents/explore.md:3 pins `model: sonnet` — oracle answers are Sonnet-tier, not opus[1m], and no agents/oracle.md exists to even carry the claimed pin.
+- **Recommended direction:** Either create agents/oracle.md as a real opus[1m]-pinned agent and change skills/oracle/SKILL.md's `agent:` to point at it, or correct docs/agent-models.md to state that oracle runs on explore/sonnet.
+
+#### H9 (high) — settings.json's mcpServers.tldr never reflects the resolved code-intel engine
+
+- **Location:** `src/setup.ts:501-513`
+- **Status:** CONFIRMED · Verifier: Confirmed by direct read of src/setup.ts:492-515. `mergeSettingsWithMcpPreservation(userSettingsPath, fullComposed, userSettingsPath, {interactive})` at line 508-513 passes the ORIGINAL `fullComposed` (never mutated) as teamSettings — the engine mutation at lines 501-507 only touched the separate `t
+- **Issue:** installSettings clones fullComposed.mcpServers into `teamMcp` and mutates ONLY that clone's tldr.command/args/serverInstructions to the resolved engine — but then calls `mergeSettingsWithMcpPreservation(userSettingsPath, fullComposed, ...)`, passing the original unmutated `fullComposed` as teamSettings. `installMcpToClaudeJson(teamMcp)` is called separately with the mutated copy. The two output files therefore get two different definitions of the same server.
+- **Scenario:** With CC_CODE_INTEL_ENGINE=native-ts (or codebase-memory), ~/.claude.json's tldr entry correctly becomes {command:"bun", args:[...]}, while ~/.claude/settings.json's mcpServers.tldr is written as the static default {command:"tldr-mcp", args:["--project","."]} from config/20-mcp.json, since resolveMcpServers/mergeSettings only ever see fullComposed. docs/settings-reference.md documents settings.json's mcpServers block as a real, first-class 'Team-Shared MCP Servers' surface (not a vestigial duplicate), so this is two files disagreeing about which engine backs the same server name.
+- **Recommended direction:** Pass the engine-mutated `teamMcp` (not `fullComposed`) into mergeSettingsWithMcpPreservation so both destinations agree, or drop mcpServers from the settings.json merge entirely and treat ~/.claude.json as the single source of truth.

+#### H11 (high) — handoff store has no per-project scoping — cross-project state bleed on resume
+
+- **Location:** `src/scripts/handoff.ts:24 (HANDOFF_DIR), :61-62, :139, :176; cf. src/scripts/checkpoint.ts:93`
+- **Status:** CONFIRMED · Verifier: Directly traced: handoff.ts:24 sets `HANDOFF_DIR = claudePath("handoffs")` with no project component anywhere — cmdCreate (line 61-62), cmdResume (139, via resolveArtifact/RESOLVE_SPEC), cmdList (176), and cmdClean (203-224) all read/write that single global directory. Compared directly against chec
+- **Issue:** checkpoint.ts scopes its artifact directory per project (`claudePath("checkpoints", project)`, project derived from `git rev-parse --show-toplevel`). handoff.ts, built on the identical artifact-store.ts helpers for the identical purpose, uses one single global directory (`claudePath("handoffs")`) with no project component anywhere in the path or the filename (`handoff_${ts}.json`/`.md` — no project prefix). The skill doc (skills/handoff/SKILL.md ~line 44-48) even shows example filenames like `project-name-2024-01-15-1430.md`, implying project-scoped naming that was never actually implemented.
+- **Scenario:** Work in project A, a handoff auto-fires (PreCompact/SessionEnd) or is saved manually, updating the global `latest.md`/`latest.json` symlinks. `cd` into project B and run `handoff.ts resume` (or `/handoff` resume, no id) — you get project A's handoff content presented as "RESUMING LATEST SESSION", with nothing in the resolution path checking that the stored `project.path`/`project.name` matches the current cwd. An agent that trusts the printed file paths/next-steps could act on stale, unrelated-project state. `cleanupHandoffs`'s keep=20 window is also shared machine-wide, so a project worked frequently can evict a rarely-visited project's only handoff.
+- **Recommended direction:** Scope HANDOFF_DIR by project the same way checkpoint.ts does (subdirectory keyed by repo toplevel basename, or embed project in the filename and filter resolveArtifact/list by cwd's project unless an explicit id is given).
+
+#### M8 (medium) — tool-cadence's own nudge/escalation text states the wrong trigger threshold
+
+- **Location:** `src/hooks/tool-cadence.ts:51,187,202`
+- **Status:** CONFIRMED · Verifier: Read src/hooks/tool-cadence.ts. THRESHOLD is defined at line 51 as `Number(process.env.CC_PARALLELMAX_THRESHOLD) \|\| 12`, and docs/hooks-reference.md:367 confirms the documented/enforced default is 12. The soft-nudge text at line 202 literally reads '...Heuristic: 3+ files or 10+ calls → delegate...'
+- **Issue:** THRESHOLD defaults to 12 (`Number(process.env.CC_PARALLELMAX_THRESHOLD) || 12`, matching docs/hooks-reference.md's documented default of 12). But both emitted messages hardcode a different number: the soft-nudge text says "Heuristic: 3+ files or 10+ calls → delegate" (line 202) and the escalation blockDecision text says "This matches a CLAUDE.md MUST-delegate trigger" referencing the same 10+ figure implicitly via CLAUDE.md's own wording ("3+ files, 10+ tool calls"). The actual code only fires the nudge at count >= 12.
+- **Scenario:** An agent reads the emitted nudge ("10+ calls") at its 10th or 11th consecutive tool call, reasons "I'm already past the stated threshold but nothing fired yet, so maybe the heuristic doesn't apply here," and continues solo for 1-2 more calls before the real (12-call) trigger lands — the tool's own guidance text misrepresents its own trigger condition to the very agent it's trying to steer.
+- **Recommended direction:** Interpolate the actual THRESHOLD constant into both message strings instead of the hardcoded literal "10+", so the emitted text can never drift from the enforced value (and stays correct if CC_PARALLELMAX_THRESHOLD is overridden).
+
+#### M12 (medium) — Three disagreeing kebab-case regexes with no shared source of truth
+
+- **Location:** `src/schemas/agent.ts:37, src/schemas/skill.ts:50, src/schemas/profile.ts:16 vs src/schemas/knowledge.ts:20 vs src/lib/lint-skills.ts:36`
+- **Status:** CONFIRMED · Verifier: Verified all four regexes by direct read: agent.ts/skill.ts/profile.ts all use the identical `/^[a-z0-9][a-z0-9-]*$/` (permits leading digit, trailing/double hyphens). knowledge.ts uses the stricter `/^[a-z0-9]+(-[a-z0-9]+)*$/` (rejects both). lint-skills.ts's separate `KEBAB_CASE` constant (`/^[a-z
+- **Issue:** Agent/skill/profile `name` fields share one regex that permits a leading digit and trailing/consecutive hyphens (e.g. "3d-", "a--b" both match). Knowledge notes use a stricter pattern that rejects both. Independently, lint-skills.ts's own `KEBAB_CASE` constant (used only for the skill *folder name*, separate from the schema's `name` field check) requires a letter as the first character, rejecting a leading digit that the schema's own `name` regex for that very same skill would accept.
+- **Scenario:** A skill folder/frontmatter pair named `3d-viewer` — frontmatter `name: 3d-viewer` — passes `SkillFrontmatter.safeParse` (schema regex allows leading digit) but fails lint-skills.ts's separate `folder-kebab-case` check on the folder name `3d-viewer` (its `KEBAB_CASE` regex requires a-z first). The same conceptual rule ("is this valid kebab-case") gives two different verdicts depending on which of the two independently-authored regexes evaluates it.
+- **Recommended direction:** Extract one shared KEBAB_CASE regex (decide once on leading-digit and trailing/double-hyphen policy) into a single module (e.g. frontmatter.ts) and reuse it in all four schemas and in lint-skills.ts's folder check.
+
+#### M15 (medium) — no-angle-brackets security scan exists only for skills, not agents or profiles
+
+- **Location:** `src/lib/lint-skills.ts:91-98 (present) vs src/lib/lint-agents.ts and src/lib/lint-profiles.ts (absent)`
+- **Status:** CONFIRMED · Verifier: Read lint-skills.ts: it does a raw regex scan of the frontmatter block for `<`/`>` with rule `no-angle-brackets` and the stated security rationale. Read lint-agents.ts and lint-profiles.ts in full — both only run lintFrontmatterCore + AgentFrontmatter/ProfileFrontmatter.safeParse and a name-match ch
+- **Issue:** lint-skills.ts raw-scans the frontmatter block for `<`/`>` with the stated rationale "security restriction, frontmatter is injected into the system prompt." Agent and profile frontmatter (particularly `description`) are read by the orchestrator and injected into context in exactly the same way, but lint-agents.ts and lint-profiles.ts have no equivalent check, and none of the three zod schemas (agent.ts/skill.ts/profile.ts) enforce it either — it's purely a linter-level raw-text scan that only one of the three linters implements.
+- **Scenario:** An agent's description field contains `<system>ignore previous instructions</system>` (or any other angle-bracket payload) copy-pasted from an external source. lint-agents.ts and frontmatter-validate.ts both report clean; the identical payload in a SKILL.md would be caught by lint-skills.ts's `no-angle-brackets` rule.
+- **Recommended direction:** Extract the angle-bracket raw scan into a shared helper (e.g. in lint-frontmatter.ts) and apply it uniformly across lint-agents.ts, lint-skills.ts, and lint-profiles.ts.
+
+#### M21 (medium) — Permission allow-list wholesale-approves git subcommands whose dangerous forms have no deny counterpart, contradicting SECURITY.md's stated enforcement boundary
+
+- **Location:** `config/30-permissions.json:11 (Bash(git branch:*)), :14 (Bash(git checkout:*)), :16 (Bash(git push:*)), deny block 69-205 (relevant entries at 102-103, 106-107)`
+- **Status:** CONFIRMED · Verifier: Verified by direct grep of config/30-permissions.json: 'git branch', 'git checkout', and 'git push' are wholesale-allowed (lines 11, 14, 16); the only deny entries are 'git push --force:*'/'git push -f:*' (102-103, literal-prefix matches that do NOT catch bundled flags like 'git push -uf'), and 'git
+- **Issue:** SECURITY.md ('Enforcement boundary: the permissions deny-list, not safety-net') states in plain terms: 'The enforcement boundary for dangerous Bash commands is the permission deny-list... That layer decides what is blocked' and 'Anything that MUST never run belongs in config/30-permissions.json, not (only) in safety-net.' But the allow-list contains bare `Bash(git branch:*)` and `Bash(git checkout:*)` with no deny-list entry for `git branch -D` (force branch delete without merge check) or bareword-pathspec `git checkout <path>` (discards uncommitted changes without `--`). Both are exactly the kind of destructive op safety-net.ts (self-documented as advisory, fail-open, and NOT the enforcement boundary) is built to catch via `looksLikePathspec` and the `branch` case in `analyzeGitAfterVerb`. The deny list also has no entry for git push's bundled short flags (e.g. `-uf`, `-fu`) that still contain `-f`; only the literal `--force`/`-f` token forms are denied, so `git push -uf origin main` matches only the broad `Bash(git push:*)` allow with no deny override.
+- **Scenario:** A prompt-injected or careless agent runs `git branch -D feature-with-unmerged-work` or `git checkout src/important.ts` (discarding uncommitted local edits) or `git push -uf origin main`. These match ONLY the broad allow-list entries (`git branch:*`, `git checkout:*`, `git push:*`) with zero deny-list coverage for the dangerous variant, so Claude Code's permission matcher auto-approves them with no user prompt. The only thing that could stop them is safety-net.ts — which SECURITY.md itself says is fail-open by design and 'a hook crash, timeout, or parser gap allows the command through.' If safety-net times out (it has a 5s hook timeout in config/40-hooks.json) or the regex misses a form, the destructive op runs silently, contradicting the doc's claim that the deny-list is what 'decides what is blocked.'
+- **Recommended direction:** Add explicit deny entries mirroring every case safety-net.ts treats as must-block: `Bash(git branch -D:*)`, `Bash(git branch -d -f:*)`, bundled `-f` push flag patterns, and either remove the bare `git checkout:*`/`git branch:*` allow entries in favor of narrower allow-lists, or add matching deny overrides for every destructive subform safety-net already enumerates.

+- **Location:** `profiles/maestro.md:6 (and nextjs.md:4, react-native.md:4, tauri.md:4, webgl.md:4, react-router.md:4)`
+- **Status:** CONFIRMED · Verifier: Verified all 6 profiles (maestro, nextjs, react-native, react-router, tauri, webgl) pin bare `model: opus` with no [1m] suffix, and CLAUDE-FULL.md:83 explicitly states 'Opus is not 1M-native, so the [1m] pin is required to keep the full window.' However, src/schemas/profile.ts:6-10 contains an expli
+- **Issue:** Every profile pins `model: opus` with no `[1m]` suffix, contradicting CLAUDE-FULL.md's explicit statement that plain Opus loses the full 1M context window and the `[1m]` pin is required — every agent file that actually uses Opus (maestro, planner) pins `opus[1m]` instead.
+- **Scenario:** A user reads profiles/maestro.md ("Deep reference: agents/maestro.md", implying parity) and manually runs `/model opus` based on its advisory model field. Per CLAUDE-FULL.md's "Context window" section ("Opus is not 1M-native, so the [1m] pin is required to keep the full window"), they silently get a truncated context window instead of the 1M window the rest of the system assumes for exactly the kind of large multi-agent orchestration these profiles exist for.
+- **Recommended direction:** Change all 6 profiles' `model:` field to `opus[1m]` to match the agent pins and CLAUDE-FULL.md's stated requirement.

+- **Location:** `MANUAL.md:568 (Hooks table, 'Setup' row) vs config/40-hooks.json (no Setup key) and src/setup.ts:77-96 (parseArgs — no --init/--init-only/--maintenance flags exist)`
+- **Status:** CONFIRMED · Verifier: Confirmed config/40-hooks.json has no 'Setup' key anywhere (grep for the literal string returns nothing), and grepped src/hooks/ and src/scripts/ for any file referencing 'Setup' — no hits. Went further than the original finding: grepped src/setup.ts's parseArgs (lines 77-96) for the CLI flags MANUA
+- **Issue:** MANUAL.md introduces its hooks table with 'cc-settings wires scripts into a subset of Claude Code's 29 hook events' and lists 'Setup | Runs on --init, --init-only, or --maintenance CLI flags' as a row. But `config/40-hooks.json` (read in full) has no `Setup` key at all, and no script under src/hooks or src/scripts references any Setup-triggered behavior — this event has nothing wired to it in cc-settings.
+- **Scenario:** A reader scanning the 'Hooks (Automatic)' table for what cc-settings does at setup time assumes there's an automated Setup-event script (consistent with every other row describing a real wired script), but no such automation exists — the row describes Claude Code's native event semantics, not a cc-settings feature.
+- **Recommended direction:** Either wire an actual Setup hook, or mark this row as 'not currently used by cc-settings' / remove it to avoid implying automation that doesn't exist.
+
+#### L4 (low) — promote-memory.ts's session_id env fallback references a stale/wrong variable name
+
+- **Location:** `src/hooks/promote-memory.ts:69`
+- **Status:** CONFIRMED · Verifier: src/hooks/promote-memory.ts:69 passes `{ session_id: "CLAUDE_SESSION_ID" }` as the env fallback key to readHookInput. docs/settings-reference.md:71 documents `CLAUDE_CODE_SESSION_ID` as the var Claude Code actually sets automatically, and src/hooks/freeze-guard.ts:35 plus src/lib/freeze.ts:7 correct
+- **Issue:** readHookInput is called with `{ session_id: "CLAUDE_SESSION_ID" }` as the env fallback. Per docs/settings-reference.md:71, the actual env var Claude Code sets automatically is `CLAUDE_CODE_SESSION_ID` — the name used correctly by src/hooks/freeze-guard.ts:35 and src/lib/freeze.ts:7. src/scripts/session-title.ts's own comment even calls `CLAUDE_SESSION_ID` an "older Claude Code build" variable, i.e. this repo already knows the name is stale.
+- **Scenario:** readHookInput's env fallback only engages when stdin JSON fails to parse (rare, since PostToolUse delivers session_id in the JSON body per docs/hooks-reference.md:109). But if stdin ever does fail to parse for this hook, `session_id` resolves to undefined (since `CLAUDE_SESSION_ID` isn't set on current Claude Code), and `seenSetPath(payload.session_id || "unknown")` collapses to the literal file `share-nudge-seen-unknown.json` — shared across any concurrent sessions hitting the same fallback path, so one session's already-nudged memory file silently suppresses the nudge for a different session/user.
+- **Recommended direction:** Change the fallback key to `CLAUDE_CODE_SESSION_ID` to match the actually-documented, currently-set env var (same fix already applied in freeze-guard.ts).
+
+#### L8 (low) — stripManagedSettings uses a weaker identity check than the sibling merge module it duplicates logic from
+
+- **Location:** `src/lib/light-profile.ts:186-188, 215-220 vs src/lib/settings-merge.ts:296 / src/lib/merge-keyed.ts:54-56`
+- **Status:** PLAUSIBLE · Verifier: Verified the code-level claim precisely: light-profile.ts never imports canonicalKey (only imports isManagedHookCommand and asRecord/subtractByKey from merge-keyed.ts), and uses raw JSON.stringify for both the hooks subtractByKey key (line 186-188) and the top-level HANDLED_KEYS comparison (line 217
+- **Issue:** settings-merge.ts's hooksStrategy explicitly switched from raw JSON.stringify identity to canonicalKey (sort-keys-deep) because 'Claude Code rewrites hook entries in its own field order... a key-order-sensitive identity made every rewritten group look user-added.' light-profile.ts's stripManagedSettings — which reimplements the same 'is this cc-settings-managed content' comparison for the light-downgrade path — never imports canonicalKey and instead uses raw `JSON.stringify(g)` for hook groups and a bare `JSON.stringify(out[key]) === JSON.stringify(full[key])` for every other top-level managed key (sandbox, spinnerVerbs, attribution, …).
+- **Scenario:** If Claude Code ever rewrites the field order of one of those managed top-level objects (as it's documented to do for hooks), a genuinely-unmodified team default fails the equality check in the HANDLED_KEYS loop and is treated as a user override — it survives the light-downgrade strip and lands in the supposedly minimal light settings.json, contradicting 'Everything else is stripped'.
+- **Recommended direction:** Import and use canonicalKey from merge-keyed.ts in stripManagedSettings's hook and HANDLED_KEYS comparisons, matching settings-merge.ts's identity function.
+
+#### L10 (low) — lint-skills.ts re-implements the frontmatter-block regex inline instead of reusing extractFrontmatterBlock
+
+- **Location:** `src/lib/lint-skills.ts:91 vs src/lib/frontmatter.ts:7-12 (FRONTMATTER_RE / extractFrontmatterBlock)`
+- **Status:** CONFIRMED · Verifier: Verified byte-for-byte: lint-skills.ts:91 does `text.match(/^---\r?\n([\s\S]*?)\r?\n---/)?.[1] ?? ""`; frontmatter.ts:7 defines `const FRONTMATTER_RE = /^---\r?\n([\s\S]*?)\r?\n---/;` used by `extractFrontmatterBlock` — an identical pattern, duplicated rather than imported. lintFrontmatterCore (call
+- **Issue:** lint-skills.ts's angle-bracket scan does `text.match(/^---\r?\n([\s\S]*?)\r?\n---/)?.[1] ?? ""` — a byte-for-byte duplicate of the regex already exported as `extractFrontmatterBlock` in frontmatter.ts (which lintFrontmatterCore, called two lines later in the same function, already uses).
+- **Scenario:** If frontmatter.ts's regex is ever changed (e.g. to tolerate a BOM, or additional delimiter variants) to fix a real parsing edge case, the inline copy in lint-skills.ts silently keeps the old behavior — the angle-bracket scan and the schema-parse scan could then disagree on where the frontmatter block even starts/ends for the same file.
+- **Recommended direction:** Replace the inline regex in lint-skills.ts with a call to `extractFrontmatterBlock(text)` from frontmatter.ts.
+
+#### L12 (low) — project-init.ts --check uses a different "is this managed" test than the rest of the file, giving a false negative when the installed version is unknown
+
+- **Location:** `src/scripts/project-init.ts:16-24 (installedVersion), :26-35 (projectAgentsVersion), :37-45 (isManaged), :99-117 (cmdCheck)`
+- **Status:** CONFIRMED · Verifier: Directly traced project-init.ts. `isManaged()` (37-45) does a substring check for 'cc-settings' in the header line and is used consistently in createCopilot/createCursor/createWindsurf (56, 73, 87) and cmdUpdate/cmdInit (137, 159). `cmdCheck` (99-129) instead only calls `projectAgentsVersion()` (26-
+- **Issue:** `isManaged()` (substring check for "cc-settings" in the first line) is the function used everywhere else in this file (createCopilot/createCursor/createWindsurf, cmdUpdate, cmdInit) to decide whether a file is cc-settings-managed. `cmdCheck` instead relies solely on `projectAgentsVersion()`, which extracts `cc-settings v([0-9.]+)` — a digits-only version regex — and treats a non-match as "not managed". When `installedVersion()` returns the literal string "unknown" (no `~/.claude/.cc-settings-version` file, e.g. running project-init.ts straight from a dev checkout before a full setup.sh install), `stampAgents()` writes a header `<!-- cc-settings vunknown | ... -->`. The version regex requires digits, so it fails to match "vunknown", `projVer` is `""`, and `cmdCheck` reports the file as NOT managed even though it unambiguously is.
+- **Scenario:** Run `project-init.ts` (or `--update`) once from a fresh dev checkout where `.cc-settings-version` hasn't been written yet → AGENTS.md gets stamped `cc-settings vunknown`. Running `project-init.ts --check` afterward prints "AGENTS.md exists (not managed by cc-settings)", contradicting the file's own header and steering the user away from `--update` (the correct next step) toward re-running `--init` unnecessarily.
+- **Recommended direction:** Have cmdCheck call `isManaged(agents)` to decide managed/unmanaged, and only use `projectAgentsVersion()` to decide up-to-date vs stale once managed status is already established.
+
+#### L15 (low) — Test title contradicts its own assertion in settings-merge.test.ts
+
+- **Location:** `tests/settings-merge.test.ts:76-82`
+- **Status:** CONFIRMED · Verifier: Read tests/settings-merge.test.ts lines 76-82 directly. Line 76: `test("null permissions on both sides → keep:false", ...)`. Line 80 comment: 'null is treated as present (not undefined), so keep:true with empty-ish object'. Line 81: `expect(result.keep).toBe(true);`. The title unambiguously says kee
+- **Issue:** The test is named `"null permissions on both sides → keep:false"`, but the code comment directly above the assertion says 'null is treated as present (not undefined), so keep:true with empty-ish object' and the assertion itself is `expect(result.keep).toBe(true)`. The title is simply wrong — a stale leftover from before the comment/assertion were corrected (or before the behavior changed), and it now actively lies about what the test verifies.
+- **Scenario:** `bun test` output prints the line "null permissions on both sides → keep:false ✓" even though the test is asserting keep:true. Anyone scanning test output (or a future maintainer changing permissionsStrategy's null-handling) is misled about the documented contract for this branch and could 'fix' the implementation to match the false title, breaking the real (intended, keep:true) behavior.
+- **Recommended direction:** Rename the test to "null permissions on both sides → keep:true (null coerces to empty object, not absent)" to match the assertion and the adjacent comment.
+
+#### L16 (low) — codemap.test.ts can execute zero assertions per test and still report pass
+
+- **Location:** `tests/codemap.test.ts:47-82`
+- **Status:** CONFIRMED · Verifier: Read tests/codemap.test.ts in full (83 lines). All four tests (lines 54, 63, 70, 76) open with `if (!(await available())) return;` per lines 47-51's own comment: 'Soft-skip the whole suite if the TypeScript compiler can't be resolved at runtime ... the engine degrades to null there.' bun:test does n
+- **Issue:** All four tests in the suite open with `if (!(await available())) return;`, a soft-skip if the native TypeScript engine can't resolve at runtime (comment: 'the engine degrades to null there'). bun:test does not fail on a test body with zero assertions — if `available()` ever returns false in an environment (e.g. a broken node_modules symlink, a TypeScript version bump that changes module resolution), all four tests report green with no assertion having run, rather than being visibly skipped or flagged.
+- **Scenario:** A future dependency bump or sandboxing change breaks TypeScript module resolution inside the test runner; getStatus(dir).available becomes false; all four codemap tests silently return early and print as passing. Anyone reading `bun test` output sees 4 green checks and no indication that native codemap functionality (structure/impact/importers/context) was never actually verified that run.
+- **Recommended direction:** Use `test.skipIf(!(await available()))` (or an equivalent) so a degraded engine shows up as explicitly skipped in test output, not indistinguishable from a real pass.

+### Affordance mismatches
+
+#### H2 (high) — maestro's documented "Agent Teams Mode" is unusable — no Team/Task tools granted
+
+- **Location:** `agents/maestro.md:14 (tools) vs 305-336 (Agent Teams Mode)`
+- **Status:** CONFIRMED · Verifier: Verified agents/maestro.md:14 tools list is exactly [Read, Write, Edit, MultiEdit, Bash, Grep, Glob, LS, TodoWrite, Agent] — no TeamCreate/TaskCreate/TaskUpdate/TaskList/TaskGet/SendMessage. Lines 305-336 ('Agent Teams Mode' / 'Teams Orchestration Pattern' / 'Inter-Agent Messaging') do instruct maes
+- **Issue:** maestro.md documents a full Agent Teams workflow (mailbox messaging, shared task list, team coordination) in its own body, but its tools: frontmatter grants none of TeamCreate, TaskCreate, TaskUpdate, TaskList, TaskGet, or SendMessage.
+- **Scenario:** User invokes maestro for "3+ independent workstreams" (which CLAUDE-FULL.md's delegation table routes to Teams). Maestro's own "Teams Orchestration Pattern" section tells it to use the shared task list and monitor teammates via mailbox, but with only [Read, Write, Edit, MultiEdit, Bash, Grep, Glob, LS, TodoWrite, Agent] in tools, it has no way to create a team, create/update tasks, or send teammate messages. Contrast agents/deslopper.md:17, which explicitly lists these tools for its narrower team-mode use.
+- **Recommended direction:** Add TeamCreate, TaskCreate, TaskUpdate, TaskList, TaskGet, SendMessage (and TeamDelete) to maestro.md's tools list, or delete the "Agent Teams Mode" section if Teams orchestration is meant to be delegated to a different agent.
+
+#### H10 (high) — Automatic (hook-driven) handoffs never populate the content the skill promises
+
+- **Location:** `src/scripts/handoff.ts:76-115 (cmdCreate); config/40-hooks.json PreCompact/SessionEnd entries invoke `handoff.ts create` with no --summary; skills/handoff/SKILL.md "What Gets Saved" list`
+- **Status:** CONFIRMED · Verifier: Directly traced: cmdCreate's `json` object (handoff.ts:76-82) hardcodes `context: { summary, activeTodos: [], keyFiles: [], currentTask: "" }, notes: ""` — only `summary` (from an optional `--summary`/`--message`/`-m` flag, line 32-37) can ever be non-empty, and the markdown template (lines 100-110)
+- **Issue:** The skill doc promises the handoff captures "Progress", "Decisions made", "Files modified", "Next steps", "Learnings". The actual JSON written by cmdCreate hardcodes `context: { summary, activeTodos: [], keyFiles: [], currentTask: "" }` and `notes: ""` — only `summary` (from an optional `--summary` flag) is ever non-empty. The markdown template's Active Todos / Key Files / Current Task / Notes sections are literal `<!-- ... -->` HTML-comment placeholders. Nothing in the codebase — no hook, no follow-up step — ever edits the file afterward to fill these in.
+- **Scenario:** PreCompact and SessionEnd both invoke `bun handoff.ts create` with no `--summary` (config/40-hooks.json). Every automatically-generated handoff is therefore an almost-empty template: `resume` on it prints headers followed by raw HTML comments for every section except git status/branch. A user relying on auto-handoff (the documented primary use case: "Auto-Handoff: The setup automatically creates handoffs") to resume next session gets none of the task/decision/next-steps context the skill claims is saved.
+- **Recommended direction:** Either have the PreCompact/SessionEnd hook path pass a real `--summary` (derived from the transcript) before exit, or have the skill instruct Claude to overwrite the placeholder sections in the just-created .md before the turn ends, and correct the skill doc to not promise automatic capture of fields the code never fills.
+
+#### H13 (high) — Oracle Compare mode requires a tool its bound agent doesn't have
+
+- **Location:** `skills/oracle/SKILL.md:6,160 vs agents/explore.md:20`
+- **Status:** CONFIRMED · Verifier: Verified directly: skills/oracle/SKILL.md line 6 (not 5 — line 5 is `context: fork`) sets `agent: explore`, and agents/explore.md line 20 is `tools: [Read, Grep, Glob, LS, Bash, WebFetch]` — no Agent/Task tool. docs/frontmatter-reference.md's own Fields table says `allowed-tools`/agent routing 'Over
+- **Issue:** Oracle's Compare mode instructs spawning parallel `Agent(explore, ...)` calls, but oracle's own frontmatter (`agent: explore`) routes the entire skill to the `explore` agent, whose tools allowlist (agents/explore.md `tools: [Read, Grep, Glob, LS, Bash, WebFetch]`) has no Agent/Task tool. Per docs/frontmatter-reference.md, only `maestro` and `deslopper` among all agents/*.md are granted `Agent`.
+- **Scenario:** User says "compare Zustand vs Jotai vs Redux Toolkit for this app." The Skill tool routes to the `explore` agent per oracle's frontmatter. The agent reaches SKILL.md step 2 ("Spawn Parallel Evaluators") and issues `Agent(explore, "Evaluate Zustand...")` three times, but the Agent tool is outside its allowlist (allowed-tools/agent bindings 'override the default tool set' per docs/frontmatter-reference.md) -- the fan-out either errors or the agent silently improvises a serial single-pass evaluation instead of the documented parallel weighted comparison, a materially different and undocumented result.
+- **Recommended direction:** Route oracle's Compare mode through an orchestrator-capable agent (e.g. maestro) or drop the `agent: explore` binding for Compare mode and let the main session do the fan-out.

+#### H14 (high) — qa's mandatory Fresh-Eyes Gate needs a tool excluded by its own allowed-tools
+
+- **Location:** `skills/qa/SKILL.md:4-5,176-181`
+- **Status:** CONFIRMED · Verifier: Verified directly: skills/qa/SKILL.md lines 4-5 show `context: fork` and `allowed-tools: [mcp__chrome-devtools__navigate_page, take_snapshot, take_screenshot, click, fill, hover, press_key, resize_page, evaluate_script]` — exactly 9 chrome-devtools tools, no Agent/Task and no Read/Write either, conf
+- **Issue:** qa's "Fresh-Eyes Gate" is marked mandatory ("Mandatory before declaring a user-reported visual bug fixed") and requires spawning a fresh subagent, but qa's frontmatter `allowed-tools` restricts the whole skill to 9 named chrome-devtools MCP tools -- no Agent/Task tool, and no Read/Write either.
+- **Scenario:** User says "is the button-color fix actually right now? check it." qa loads with allowed-tools scoped to navigate_page/take_snapshot/take_screenshot/click/fill/hover/press_key/resize_page/evaluate_script only. Step 2 of the gate ("Spawn a fresh subagent and pass ONLY the images...") has no tool available to do so, so the mandatory unprimed second-look is silently skipped and the skill falls back to the same primed reviewer whose blind spot the gate exists to catch.
+- **Recommended direction:** Add the Agent tool to qa's allowed-tools list, or move the Fresh-Eyes Gate's subagent-spawn step to the calling context that isn't tool-restricted.

+#### M5 (medium) — 'Pre-commit verification' guardrail claims tsc + build + tests are all enforced automatically, but only tsc is hooked
+
+- **Location:** `MANUAL.md:492 vs src/scripts/pre-commit-tsc.ts (full file) and config/40-hooks.json (PreToolUse Bash block, lines ~33-60)`
+- **Status:** CONFIRMED · Verifier: Read src/scripts/pre-commit-tsc.ts in full: it runs only `runTsc()` (tsc --noEmit) and blocks on `error TS` matches or nonzero exit; there is no build or test invocation anywhere in the file. Grepped config/40-hooks.json for 'build' and 'test': zero matches anywhere in the file, confirming no hook r
+- **Issue:** MANUAL.md's 'Guardrails (Always Active)' section states these are 'enforced automatically — no skill needed', including 'Pre-commit verification — tsc + build + tests must pass before any commit'. Reading `src/scripts/pre-commit-tsc.ts` (the only hook wired to `git commit*` in config/40-hooks.json) shows it runs `tsc --noEmit` only — there is no hook anywhere that runs a build command or `bun test` before a commit is allowed.
+- **Scenario:** A user or agent with a failing test suite or broken build (but no TypeScript errors) runs `git commit` — the commit succeeds because nothing hooked to `PreToolUse(Bash)` checks build/test status, directly contradicting the doc's claim that this is 'always active' and requires 'no skill'.
+- **Recommended direction:** Either add build/test enforcement to the pre-commit hook chain, or reword the guardrail to state that build/test verification is a prose discipline (AGENTS.md 'Pre-Commit Verification') the agent is expected to follow manually, distinct from the tsc hook that is actually automated.
+
+#### M10 (medium) — Light-profile downgrade can leave a cc-settings hook active in a mixed hook group
+
+- **Location:** `src/lib/light-profile.ts:165-198 (stripManagedSettings hooks handling)`
+- **Status:** CONFIRMED · Verifier: Verified against src/lib/light-profile.ts:165-198. The hooks handling does exactly: subtractByKey (JSON.stringify identity) against full baseline groups, then `.filter((g) => !isAllCcScriptGroup(g))` where isAllCcScriptGroup requires ALL commands in the group to be managed (line 172-178, `.every(...
+- **Issue:** A user hook group survives the light-downgrade strip unless it (a) is byte-identical (JSON.stringify) to a group in the full baseline, OR (b) every hook command inside it is cc-settings-managed. A group containing one team-managed hook plus one genuinely user-added hook fails both checks and is kept whole — including the cc-settings hook — even though light explicitly promises 'no hooks (except statusLine)'.
+- **Scenario:** A user manually adds their own PreToolUse hook into the SAME group array as cc-settings' safety-net.ts (e.g. same matcher, hooks:[safety-net.ts, my-custom-hook.sh]). Running `bash setup.sh --light` on top of that full install calls stripManagedSettings, whose subtractByKey (raw JSON.stringify identity) doesn't match the full baseline's single-hook group, and isAllCcScriptGroup's `.every(...)` fails because one hook isn't managed — so the whole mixed group, safety-net.ts included, is written into the supposedly hook-free light settings.json.
+- **Recommended direction:** Filter at the individual-hook level (drop managed hooks from the array, keep the rest) rather than all-or-nothing at the group level, mirroring pruneDeprecatedHooks' partial-prune approach already used in settings-merge.ts.
+
+#### M11 (medium) — AgentFrontmatter schema silently drops typo protection for 3 documented agent fields
+
+- **Location:** `src/schemas/agent.ts:33-56 (AgentFrontmatter is z.looseObject with no `skills`, `background`, or `allowedTools` keys)`
+- **Status:** CONFIRMED · Verifier: Read src/schemas/agent.ts in full: AgentFrontmatter is z.looseObject with typed optional fields for model/tools/disallowedTools/maxTurns/permissionMode/effort/isolation/memory/color/initialPrompt/hooks/mcpServers — no entry for `skills`, `background`, or `allowedTools`. docs/frontmatter-reference.md
+- **Issue:** docs/frontmatter-reference.md documents `skills` (list, skills to preload), `background` (boolean, always run as background task), and `allowedTools` (list, alias for `tools`, "both field names are accepted") as valid agent frontmatter fields, but AgentFrontmatter only types name/description/model/tools/disallowedTools/maxTurns/permissionMode/effort/isolation/memory/color/initialPrompt/hooks/mcpServers. Because AgentFrontmatter is z.looseObject, any of these three keys — or a typo of them — passes straight through unvalidated.
+- **Scenario:** An author writes `allowedTools: [Read, Bash]` (per the doc) or `backgroud: true` (typo) in agents/foo.md. AgentFrontmatter.safeParse succeeds either way (unknown keys pass through in a loose object), lint-agents.ts reports 0 errors, and frontmatter-validate.ts's install-time check also passes — yet the field silently does nothing (the real field is `tools`, and `backgroud` is never read by anything), directly contradicting frontmatter-validate.ts's own header comment: "Catches typos like `effort: xtreme`, `permissionMode: planning`... before the installer ships a broken agent." It does not catch this class of typo at all.
+- **Recommended direction:** Add typed optional fields for `skills: z.array(z.string())`, `background: z.boolean()`, and `allowedTools: z.array(z.string())` (or normalize allowedTools→tools at parse time) to AgentFrontmatter so these documented fields get the same typo protection as every other agent field.
+
+#### M22 (medium) — Write(~/.claude/settings.json) deny rule is bypassable via the wildcard-allowed Edit/MultiEdit tools, which aren't covered by any settings.json-specific deny entry
+
+- **Location:** `config/30-permissions.json:61-62 (Edit(*), MultiEdit(*) in allow), :134-135 (Write(~/.claude/settings.json), Write(~/.claude.json) in deny), src/hooks/pre-edit-validate.ts (generic Edit validation, no settings.json-specific check)`
+- **Status:** CONFIRMED · Verifier: Confirmed via grep: Edit(*) and MultiEdit(*) are unconditionally allowed (lines 61-62) with zero path restriction; the deny block only names Write(~/.claude/settings.json) and Write(~/.claude.json) (134-135) plus Bash cp/mv variants (193-194) — no Edit(...)/MultiEdit(...) deny entry for either file 
+- **Issue:** The permissions config denies the `Write` tool from touching `~/.claude/settings.json` (and `~/.claude.json`) — the file the entire Shai-Hulud defense is built around protecting. But the allow-list separately grants `Edit(*)` and `MultiEdit(*)` unconditionally (no path restriction at all), and the deny-list has no `Edit(~/.claude/settings.json)` or `MultiEdit(~/.claude/settings.json)` entry to close that second tool surface. Claude Code's Edit/MultiEdit tools operate on arbitrary file paths just like Write; denying only one of the three file-mutation tool families for this specific path gives an illusion of coverage that the config itself doesn't actually provide.
+- **Scenario:** A prompt-injection payload (e.g. embedded in a file Claude reads, or a compromised MCP tool response) instructs Claude to use the Edit tool — not Write — to append a `SessionStart` hook entry into `~/.claude/settings.json`. The Write-specific deny rule never triggers because Edit is a different tool name; `Edit(*)` in the allow-list matches with no deny override, and the edit proceeds. (The fingerprint check would eventually flag this at next SessionStart, but only after the tampered config has already been live for the remainder of the current session and would re-run on every subsequent session until a human intervenes — the real-time prevention the deny-list is supposed to provide for this exact file doesn't hold.)
+- **Recommended direction:** Add `Edit(~/.claude/settings.json)` and `MultiEdit(~/.claude/settings.json)` (and the `.claude.json` equivalents) to the deny-list alongside the existing Write entries so all three mutation tools are actually covered for this path.

+- **Location:** `src/setup.ts:212-257 (createBackup), src/setup.ts:309-351 (cleanOldConfig)`
+- **Status:** CONFIRMED · Verifier: Verified all claims by reading src/setup.ts:212-257 (createBackup only tars .claude/settings.json, .claude/CLAUDE.md, .claude/AGENTS.md, .claude.json — lines 222-227) and :309-351 (cleanOldConfig unconditionally rm -rf's scripts/, lib/, hooks-config*.json, agents/*.md, skills/*.{json,md}, every MANA
+- **Issue:** createBackup() only tars ~/.claude/settings.json, CLAUDE.md, AGENTS.md, and ~/.claude.json. cleanOldConfig(), which always runs before the copy phase (both full and light profiles), unconditionally deletes agents/*.md, skills/*.md and every MANAGED_SKILLS directory, rules/*.md, profiles/*.md, docs/*.md, hooks/*.md, contexts/, scripts/, lib/, hooks-config*.json. createBackup's own error path explicitly frames itself as the guarantee that makes this safe: 'Aborting so --rollback stays possible.'
+- **Scenario:** A copy step after cleanOldConfig fails (EACCES on one file in profiles/, disk fills up mid `bun install`, or the process is killed) — main()'s outer catch logs 'Setup failed' and exits 1, but by then agents/, skills/ (all managed skill dirs), rules/, profiles/, docs/, and hooks/ have already been emptied. Running `bun src/setup.ts --rollback` per the printed advice restores only the 4 backed-up files — none of the wiped directories come back. The user is left with no skills/agents/rules until they successfully complete a full re-run, and the advertised recovery path does nothing for the actual damage.
+- **Recommended direction:** Either widen createBackup to snapshot the managed directories too (tar the whole ~/.claude minus tldr-cache/logs/backups), or make cleanOldConfig's deletions conditional on the subsequent copy succeeding (stage-then-swap) so a mid-install failure never leaves a half-wiped ~/.claude.

+- **Status:** CONFIRMED · Verifier: Verified agents/deslopper.md:17 tools list contains TeamCreate but not TeamDelete, and line 361 (step 10 of the Team Mode Workflow) says 'Shutdown scanners ... then TeamDelete.' The tool is referenced but not granted, confirming every team-mode deslop run cannot clean up its own team object via its 
+- **Issue:** Team Mode Workflow step 10 instructs the agent to call TeamDelete after shutting down scanners, but TeamDelete is absent from the agent's tools list (only TeamCreate is granted, not TeamDelete).
+- **Scenario:** Coordinator runs team mode (>=100 files or user says "use teams"), spawns 3 explore scanners via TeamCreate, completes the report cycle, then reaches step 10 ("Shutdown scanners ..., then TeamDelete") — but TeamDelete isn't in the allowed tools array, so every team-mode deslop run leaks a team object with no way for the agent to clean it up.
+- **Recommended direction:** Add TeamDelete to deslopper.md's tools list.

+- **Status:** CONFIRMED · Verifier: Live-reproduced the exact scenario by running `bun run upstream:scan` at HEAD: output was 'manifest version: 2.1.202 ... live version: 2.1.204 ... drift detected: settings keys: in schema but NOT in manifest → advisorModel'. Confirmed src/schemas/settings.ts:159 has `advisorModel: z.string().optiona
+- **Issue:** Every non-version diff in scan.ts (settings keys, hook events/types, permission modes, mcp transports, agent isolation/memory) compares `upstream/claude-code-manifest.json` against src/schemas/*.ts — both are maintained by the same cc-settings authors, updated "by hand via the /cc sync skill" after a human reads the changelog. The only check that touches an actual external source is the npm version-number fetch. Running it live right now demonstrates the gap: `bun run upstream:scan` reports `settings keys: in schema but NOT in manifest → advisorModel` — a field src/schemas/settings.ts's own inline comment says was added in Claude Code 2.1.98, still missing from the manifest at HEAD (26dc624) with `claudeCodeVersion: "2.1.202"` recorded.
+- **Scenario:** Anthropic ships a new hook event or settings key in a release; the human running `/cc sync` updates src/schemas/*.ts but forgets (or defers) updating upstream/claude-code-manifest.json in the same pass — exactly what happened with `advisorModel`. The `upstream-scan` CI job (ci.yml) is explicitly dry-run/non-blocking ("Not a gate"), so this drift can sit in `main` indefinitely with no red X anywhere, while a genuinely new-to-Anthropic field that nobody has transcribed into either file yet is structurally undetectable by this tool at any point — there is no external ground truth being consulted beyond the version string.
+- **Recommended direction:** Either land the missing advisorModel manifest entry now (quick fix), and/or add a lightweight CI assertion (not necessarily blocking) that fails loudly, or a scheduled reminder, when manifest-vs-schema drift like this survives more than N days — the current design has no mechanism to force staleness to get fixed rather than just observed.
+
+#### M20 (medium) — proof.ts discards stdout/stderr from the core gates, so a failing verdict carries zero diagnostic detail
+
+- **Location:** `src/lib/proof-of-work.ts:79-87 (runGate) vs :102-133 (runReactDoctor/runDeslop, which DO capture output)`
+- **Status:** CONFIRMED · Verifier: Directly traced proof-of-work.ts: `runGate` (lines 79-87) spawns with `stdout: "ignore", stderr: "ignore"` and returns `{ gate, status }` only — no `detail` field is ever set for core gates. `formatReport` (line 70) only appends `— ${r.detail}` when `r.detail` is truthy, so a failing typecheck/test/
+- **Issue:** `runGate` spawns `bun run <script>` with `stdout: "ignore", stderr: "ignore"` and returns only pass/fail — no `detail`. `formatReport` only prints a detail when one exists, so a failing typecheck/test/lint gate renders as bare `✗ typecheck` with no error text, while the two OPTIONAL advisory probes (react-doctor, deslop) do capture and surface their output as `detail`.
+- **Scenario:** An agent runs `bun run proof`, sees `NOT review-ready ✗ — fix the failing gate(s) before this reaches a human` with no indication of what failed or where, and must separately re-run `bun run typecheck`/`test`/`lint` to get the actual errors — defeating the tool's stated purpose ("prints one verdict") exactly in the failure case where information is most needed. The skill doc (skills/proof-of-work/SKILL.md) doesn't mention this gap either.
+- **Recommended direction:** Capture stdout+stderr for the core gates too (pipe instead of ignore) and surface a tail of the failing gate's output as `detail`, same as the advisory probes already do.
+
+#### M25 (medium) — pre-edit-validate.ts and delegation-detector.ts have zero behavioral test coverage — only the blanket fail-open smoke test touches them
+
+- **Location:** `src/hooks/pre-edit-validate.ts:63-100; src/hooks/delegation-detector.ts:34-63`
+- **Status:** CONFIRMED · Verifier: Read both hook files in full. pre-edit-validate.ts:63-100 contains exactly the described logic: exact-match check (line 64), line-count warning >15 (line 78), and a manual indexOf-loop occurrence counter (lines 87-94, searchFrom = found + oldString.length) that would silently miscount if changed to 
+- **Issue:** Both hooks contain real, non-trivial decision logic: pre-edit-validate.ts counts occurrences of old_string via a manual indexOf loop and blocks/warns based on file-existence, exact-match, line-count, and ambiguity checks; delegation-detector.ts scores a prompt against 11 regexes plus path-token and list-item heuristics and emits a steering message above a threshold. Neither appears in any test file except tests/hook-fail-open.test.ts, which only feeds garbage TOOL_INPUT/stdin and asserts exit 0 — it never exercises the real branches (missing file, exact-match found/not-found, >15-line old_string, >1 occurrence, breadth-phrase scoring, path/list-item counting). Compare to safety-net.ts and tool-cadence.ts, which have 60+ and 250+ lines of dedicated positive/negative test cases respectively for comparably-shaped logic.
+- **Scenario:** A future edit to pre-edit-validate.ts's occurrence-counting loop (e.g. `searchFrom = found + 1` instead of `found + oldString.length`) would silently miscount overlapping occurrences and either over- or under-warn on ambiguous edits — nothing in the suite would fail. Likewise a threshold typo in delegation-detector.ts (`score < 2` becoming `score < 20`) would silently disable the maestro-routing nudge for every prompt, and CI would stay green because the fail-open smoke test only checks 'garbage input doesn't crash the hook.'
+- **Recommended direction:** Add dedicated test files (pre-edit-validate.test.ts, delegation-detector.test.ts) spawning the hook with realistic TOOL_INPUT/prompt payloads and asserting block/allow/warn output, mirroring the pattern already used for safety-net.test.ts and tool-cadence.test.ts.
+
+#### M26 (medium) — tests/manual-sync.sh is fully dead — never invoked by CI, package.json, or docs
+
+- **Location:** `tests/manual-sync.sh:1-161 (full file; header/usage comment is lines 1-9)`
+- **Status:** CONFIRMED · Verifier: Read tests/manual-sync.sh in full (161 lines) — it's a real, working bash drift-checker (checks skills/agents/hooks are mentioned in MANUAL.md), not a stub. Grepped package.json scripts (23 entries, none reference manual-sync), .github/workflows/ci.yml (4 jobs: typecheck, test, lint, schemas, upstre
+- **Issue:** The script's own header says 'Usage: bash tests/manual-sync.sh' and it checks that every skill/agent/profile is mentioned in MANUAL.md. It is a bash script, so `bun test` never picks it up. Grepping package.json, .github/workflows/ci.yml, MANUAL.md, AGENTS.md, and docs/*.md for 'manual-sync' returns zero hits — nothing runs it, ever, anywhere.
+- **Scenario:** A contributor adds skills/foo-bar/SKILL.md (or an agent, or a profile) and forgets to add it to MANUAL.md. `bun test` is green, `bun run lint:*` is green, CI is green, the PR merges. MANUAL.md silently drifts from the real skill/agent/profile list forever, because the one check built specifically to catch this requires a human to remember an undocumented, unwired shell command.
+- **Recommended direction:** Either wire it into CI (a `manual-sync` job or step) or delete it — a lint that exists only in the tests/ directory tree but is never executed is worse than no lint, because it creates the false impression that MANUAL.md drift is caught.
+
+#### L14 (low) — CI's lint:knowledge step is a guaranteed no-op that has never linted real content
+
+- **Location:** `.github/workflows/ci.yml:56-62; src/scripts/lint-knowledge.ts:16-34`
+- **Status:** CONFIRMED · Verifier: Read .github/workflows/ci.yml lines 44-62 and src/scripts/lint-knowledge.ts lines 1-34. The CI step name and its own inline comment (lines 56-61) literally say 'lint:knowledge (no-op without KNOWLEDGE_REPO_PATH)' and 'this only proves the script runs cleanly ... it does not lint real notes yet.' lin
+- **Issue:** The CI 'lint' job runs `bun run lint:knowledge` unconditionally, but lint-knowledge.ts's main() returns 0 immediately (printing 'No knowledge directory specified') whenever both the CLI arg and KNOWLEDGE_REPO_PATH env var are absent — which is always the case in CI, since no team-knowledge checkout exists in the workflow. The CI comment itself acknowledges this ('no-op without KNOWLEDGE_REPO_PATH'), but the practical effect is exactly the pattern this audit is looking for: a CI step gated on an env var CI never sets, producing a permanent green checkmark that verifies nothing.
+- **Scenario:** A regression in lint-knowledge.ts's actual linting logic (schema checks, name/filename mismatch, supersedes-unknown warning) would only be caught by tests/lint-knowledge.test.ts's synthetic-fixture unit tests — never by the CI step whose name implies it lints the real shared knowledge corpus. If those unit tests were ever weakened or a rule regressed in a way the synthetic fixtures don't cover, nothing in CI would notice.
+- **Recommended direction:** Either check a small fixture knowledge dir into the repo for CI to lint (closing the gap the CI comment flags as deliberately open), or rename the CI step so it doesn't read as "knowledge notes are linted in CI" when they are not.
+
+### Boundary & safety
+
+#### H12 (high) — Fingerprint/manifest/engine-pin integrity checks cover only three narrow slices of settings.json — mcpServers, permissions, and env are completely unprotected and this gap is undocumented
+
+- **Location:** `src/lib/hooks-fingerprint.ts:56-61 (hashHooks reads only settings.hooks), src/lib/hook-command.ts:66-90 (iterCommandHooks unwraps only .hooks), src/lib/audit-hooks.ts:279-281 (auditHooks reads only settings.hooks), SECURITY.md:212-227`
+- **Status:** CONFIRMED · Verifier: Read hashHooks (hooks-fingerprint.ts:56-61): 'const hooks = (settings as Record<string, unknown>).hooks ?? {}' — only the hooks key is hashed. Read iterCommandHooks (hook-command.ts) and auditHooks (audit-hooks.ts:279-281, 'const hooks = (settings as Record<string, unknown>).hooks') — both explicitl
+- **Issue:** `hashHooks()` computes its SHA256 over `(settings as Record<string, unknown>).hooks ?? {}` only — every other top-level key in settings.json (`mcpServers`, `permissions`, `env`, `statusLine`, `model`, etc.) is invisible to the fingerprint. `mcpServers` entries execute arbitrary local commands with full startup — a stronger and stealthier persistence primitive than a hook (no `type: command` shape, not walked by `iterCommandHooks`/`auditHooks` at all, and not scanned by the suspicious-pattern regexes since those only run against extracted hook command strings). SECURITY.md's 'What the content manifest does not cover' section lists the bun binary, node_modules, non-.ts files, and 'coordinated tampering of manifest+fingerprint+settings together' as out of scope — but never states that non-hooks keys of settings.json (most critically mcpServers) are entirely outside the THREE integrity checks even for uncoordinated, single-key tampering that leaves the hooks block byte-for-byte untouched.
+- **Scenario:** Malware (or a compromised package's postinstall) appends a malicious entry to settings.json's `mcpServers` block (e.g. `{"command": "node", "args": ["/tmp/payload.js"]}`) without touching the `hooks` key at all. `verifyAgainstSettings()` re-hashes only `.hooks`, computes the same hash as before, and reports `status: "match"` — completely silent, no warning, no audit trigger. `bun run audit:hooks` also only walks `settings.hooks` (auditHooks() explicitly reads `(settings as Record<string, unknown>).hooks`), so even a manual audit run never sees the injected MCP server. The malicious server runs with full local privileges on every Claude Code session start, and every one of cc-settings' three advertised integrity layers reports clean.
+- **Recommended direction:** Either extend the fingerprint/audit surface to cover mcpServers (and ideally permissions, env) or explicitly document in SECURITY.md that only the hooks block is defended and mcpServers/permissions/env are an acknowledged blind spot — the current doc's scope language ('what the content manifest does not cover') implies a narrower gap than what actually exists.
+
+#### M23 (medium) — log-bash.ts logs every Bash command in near-plaintext using a redaction function that misses GitHub tokens, AWS keys, and password= patterns that a sibling module already redacts
+
+- **Location:** `src/scripts/log-bash.ts:53-54 (escapeForLog → sanitizeOutput), src/lib/codex.ts:259-267 (sanitizeOutput, 4 patterns), src/hooks/safety-net.ts:25-33 (redactSecrets, 7 patterns)`
+- **Status:** CONFIRMED · Verifier: Confirmed sanitizeOutput (codex.ts:259-267) has exactly 4 redaction rules: sk-*, Bearer, Authorization:, and *_API_KEY/TOKEN/SECRET=value. Confirmed redactSecrets (safety-net.ts:25-33) has 7, including ghp_[A-Za-z0-9]{10,}, AKIA[A-Z0-9]{12,}, and password=/token=/secret= query-string forms that sani
+- **Issue:** log-bash.ts is a PostToolUse hook that appends EVERY Bash command (not just blocked ones) to `~/.claude/logs/bash-<date>.log` via `escapeForLog`, which calls `sanitizeOutput` from codex.ts. `sanitizeOutput`'s secret-redaction coverage is only 4 patterns: `sk-[16+ chars]`, `Bearer <token>`, `Authorization: <token>`, and `*_API_KEY/TOKEN/SECRET=value`. The safety-net.ts module, auditing the SAME kind of untrusted command string but only for BLOCKED commands, has its own `redactSecrets` with 7 patterns including `ghp_[A-Za-z0-9]{10,}` (GitHub PATs), `AKIA[A-Z0-9]{12,}` (AWS access key IDs), and `password=...`/`secret=...` query-string forms — none of which sanitizeOutput covers. Because log-bash logs the full corpus of routine command usage (not just malicious/blocked attempts), it is actually the higher-exposure surface, yet it inherits the weaker of the two redaction implementations.
+- **Scenario:** A user runs `git clone https://ghp_1234567890abcdefghijklmnop@github.com/org/repo.git` or `aws configure set aws_secret_access_key AKIAIOSFODNN7EXAMPLE` or `curl -u user:password=hunter2 https://api.example.com` in Bash. log-bash.ts's PostToolUse hook fires, calls `escapeForLog` → `sanitizeOutput`, none of whose 4 regexes match `ghp_...`, `AKIA...`, or `password=...` — the full command including the live credential is written verbatim into `~/.claude/logs/bash-YYYY-MM-DD.log`, a plaintext file with default 1-day retention (configurable higher via `CLAUDE_LOG_RETENTION_DAYS`) that any process or user with local read access can grep.
+- **Recommended direction:** Either have log-bash.ts also call safety-net's redactSecrets (or better, unify the two into one shared secret-redaction function covering the union of both pattern sets) so the routine-logging path isn't weaker than the blocked-command logging path.
+
+#### L5 (low) — statusline.ts trusts review-queue.json / version-drift.json without schema validation, unlike its own quota cache
+
+- **Location:** `src/hooks/statusline.ts:211,222`
+- **Status:** PLAUSIBLE · Verifier: Confirmed the structural asymmetry: src/lib/quota.ts defines and applies zod schemas (RateLimitWindowSchema, RateLimitsCacheSchema, QuotaSteerStateSchema) via `.safeParse()` before use, while src/hooks/statusline.ts:211 and :222 read review-queue.json/version-drift.json via the raw, unvalidated `rea
+- **Issue:** statusline.ts reads `rate-limits.json` via quota.ts's `readRateLimitsCache()`, which zod-validates with `RateLimitsCacheSchema.safeParse` and returns null on any shape mismatch. But the same file reads `review-queue.json` and `version-drift.json` via the raw, unvalidated `readState<T>(name, fallback)` — which only catches file-read/JSON-parse errors, not shape mismatches — and directly does arithmetic/comparisons on the result (`reviewQueue.awaiting > 0`, `reviewQueue.awaiting >= maxUnreviewed()`, `ageMs(reviewQueue, ...)`).
+- **Scenario:** If `~/.claude/tmp/review-queue.json` or `version-drift.json` is ever written by a future code path (or corrupted/partially-written by a bug, or tampered with) with an unexpected shape — e.g. `awaiting` as a string, or `firstSpawnAt` missing where the type declares it optional but callers assume a number — `ageMs()`/comparisons silently produce `NaN`/`false` results rendered straight into the visible statusline (e.g. `NaN%` age label, or a permanently-suppressed/permanently-shown review warning) rather than gracefully degrading like the validated quota-cache path does.
+- **Recommended direction:** Add lightweight zod schemas (or at least manual type guards) for ReviewQueueState and the version-drift shape, mirroring the RateLimitsCacheSchema pattern already used in the same file, so a malformed state file degrades the same way a malformed quota cache does.

+#### H5 (high) — MANUAL.md documents a 'core' Sanity MCP server that setup.sh never installs
+
+- **Location:** `MANUAL.md:472 and mcp-configs/recommended.json (Sanity block, marked _status: core) vs config/20-mcp.json (actual composed source, no Sanity entry) and src/setup.ts (no Sanity install logic)`
+- **Status:** CONFIRMED · Verifier: Read config/20-mcp.json in full: only context7, tldr, figma, chrome-devtools are declared — no Sanity entry. MANUAL.md:472 lists `Sanity` in the table introduced by 'a core set of MCP servers — installed automatically by setup.sh into ~/.claude.json'. Also checked mcp-configs/recommended.json, which
+- **Issue:** MANUAL.md's 'MCP servers (core vs optional)' table lists `Sanity` under servers that are 'a **core** set of MCP servers — installed automatically by `setup.sh` into `~/.claude.json`', described as used by 'satus / novus projects with Sanity integration'. But `config/20-mcp.json` (the actual composed-settings source, confirmed by reading it in full) only declares `context7`, `tldr`, `figma`, and `chrome-devtools` — there is no `Sanity` entry anywhere in `config/`, `src/`, or the plugin manifest (only a stray code comment references 'Sanity' auth-cache pruning, suggesting it may have existed and been removed without updating the doc).
+- **Scenario:** A new joiner reads MANUAL.md, expects a working Sanity MCP connector after running `bash setup.sh` on a satus project with a CMS integration, and finds no Sanity tools registered at all — with no explanation, since the doc calls it 'core' and 'automatic'.
+- **Recommended direction:** Either add a Sanity entry to config/20-mcp.json (if it's meant to be shipped) or move the row to the 'Optional' table in MANUAL.md and describe how to add it manually (as is done for github/vercel/memory).
+
+#### M1 (medium) — AgentIsolation schema rejects the exact mitigation value the docs tell users to set
+
+- **Location:** `src/schemas/agent.ts:30 (enum) vs docs/feature-agents-guide.md:363 (mitigation text) vs src/setup.ts:686-688 and src/lib/lint-agents.ts (enforcement path)`
+- **Status:** CONFIRMED · Verifier: Confirmed AgentIsolation = z.enum(["worktree","remote"]) in src/schemas/agent.ts:30, and docs/feature-agents-guide.md:363 literally says 'Or pass isolation: "head" ... so the subagent runs against the live worktree' — a value the enum rejects. However the finding overstates the mechanism: src/setup.
+- **Issue:** AgentIsolation is a strict zod enum of only ["worktree", "remote"], but docs/feature-agents-guide.md:363 explicitly instructs users to set isolation: "head" as the fix for the base-ref gotcha — a value the schema has no room for.
+- **Scenario:** A user follows docs/feature-agents-guide.md's own mitigation ("Or pass isolation: 'head' ... so the subagent runs against the live worktree") and adds `isolation: "head"` to a feature agent. frontmatter-validate.ts parses it against AgentFrontmatter, AgentIsolation.enum(["worktree","remote"]) rejects "head", and the agent fails install-time validation — the documented fix doesn't work.
+- **Recommended direction:** Either add "head" to the AgentIsolation enum (if it's a real accepted value upstream) or correct docs/feature-agents-guide.md to only recommend omitting isolation entirely.

+#### M3 (medium) — frontmatter-reference.md's canonical model table is stale for implementer and reviewer
+
+- **Location:** `docs/frontmatter-reference.md:85,87`
+- **Status:** CONFIRMED · Verifier: Verified docs/frontmatter-reference.md:85 lists implementer=opus and :87 lists reviewer=opus[1m], while agents/implementer.md:3 and agents/reviewer.md:3 both read `model: sonnet`, matching docs/agent-models.md:20-21 exactly. Table is genuinely stale. Downgraded from high to medium: this is a pure re
+- **Issue:** The "All Agents in cc-settings" table lists implementer=opus and reviewer=opus[1m], but both agent files pin model: sonnet, and docs/agent-models.md's own routing table (already updated for the Sonnet-5 downshift) also says sonnet for both — the table just wasn't updated alongside the migration.
+- **Scenario:** Anyone consulting docs/frontmatter-reference.md — the file this audit is explicitly told to check agent frontmatter against — to answer "what model does implementer/reviewer run on" gets the wrong answer on both. agents/implementer.md:3 and agents/reviewer.md:3 both read `model: sonnet`, matching docs/agent-models.md:20-21. A user reasoning about Opus quota consumption from this table over-budgets Opus wall-time for two agents that never touch it.
+- **Recommended direction:** Update the two table rows in docs/frontmatter-reference.md to `sonnet`, matching agents/implementer.md, agents/reviewer.md, and docs/agent-models.md.

+#### M4 (medium) — rules/README.md overclaims react-perf.md's trigger paths (.ts files never actually load it)
+
+- **Location:** `rules/README.md:34 vs rules/react-perf.md:1-6`
+- **Status:** CONFIRMED · Verifier: Verified rules/README.md:34 states react-perf.md loads for '.tsx, .ts, components/, or app/' but rules/react-perf.md:2-5 frontmatter paths are only ["**/*.tsx", "components/**/*", "app/**/*"] — no **/*.ts glob. A plain .ts file (e.g. a hook file) genuinely would not trigger this rule despite the REA
+- **Issue:** README claims react-perf.md loads for `.ts`, `.tsx`, `components/`, or `app/` files, but the actual frontmatter only globs `**/*.tsx`, `components/**/*`, `app/**/*` — there is no `**/*.ts` pattern.
+- **Scenario:** A developer edits `lib/hooks/use-scroll.ts` (plain .ts, containing hook logic with re-render/effect-dependency concerns) expecting react-perf.md's rules to auto-load per the README's explicit claim. Because the frontmatter lists no `**/*.ts` glob, the rule never loads for that file, silently omitting the React Compiler / effect-dependency guidance for any non-JSX TypeScript file.
+- **Recommended direction:** Either add `**/*.ts` to rules/react-perf.md's paths frontmatter, or fix the README row to say ".tsx, components/, or app/" (dropping the false ".ts" claim).

+
+- **Location:** `docs/hooks-reference.md 'Configured Hooks' section (approx. lines 312-500 in the rendered file) vs config/40-hooks.json:27,78,130,180`
+- **Status:** CONFIRMED · Verifier: Grepped config/40-hooks.json for all four script names and confirmed each is wired: quota-steer.ts (line 27), freeze-guard.ts (line 78), promote-memory.ts (line 130), codex-verify.ts (line 180). Grepped docs/hooks-reference.md's 'Configured Hooks' section for the same four names: zero matches. Read 
+- **Issue:** The canonical 'Configured Hooks' reference (meant to be the authoritative per-event list of what cc-settings actually wires) omits: `quota-steer.ts` (UserPromptSubmit — present in config/40-hooks.json:27 and documented conceptually in CLAUDE-FULL.md/agent-models.md, but never listed in this reference table), `freeze-guard.ts` (PreToolUse Edit|Write|MultiEdit — config/40-hooks.json:78), `promote-memory.ts` (PostToolUse Write|Edit — config/40-hooks.json:130), and `codex-verify.ts` (SessionStart, async — config/40-hooks.json:180). All four files were confirmed to exist on disk under src/hooks/.
+- **Scenario:** A maintainer debugging why a freeze-guard block fired, or why quota-steer injected routing guidance, consults docs/hooks-reference.md's 'Configured Hooks' section (the doc explicitly designed for this) and finds no mention of the responsible script — they conclude it must be a bug or third-party hook rather than a documented cc-settings feature.
+- **Recommended direction:** Add rows for quota-steer.ts, freeze-guard.ts, promote-memory.ts, and codex-verify.ts to the corresponding event sections in docs/hooks-reference.md's 'Configured Hooks' table.
+
+#### M7 (medium) — pre-edit-validate.ts header claims Edit+Write coverage; config wires Edit only
+
+- **Location:** `src/hooks/pre-edit-validate.ts:2 vs config/40-hooks.json:63-72`
+- **Status:** CONFIRMED · Verifier: src/hooks/pre-edit-validate.ts:2 reads 'PreToolUse guard for Edit/Write calls.' Confirmed via grep that config/40-hooks.json only registers this hook under `"matcher": "Edit"` (line 64), while sibling file-mutation hooks in the same config use broader matchers: line 74 is `"Edit\|Write\|MultiEdit"`, a
+- **Issue:** The file's header comment reads "Pre-Edit Validation Hook — PreToolUse guard for Edit/Write calls," but config/40-hooks.json registers it with `"matcher": "Edit"` only (contrast with the freeze-guard entry two blocks below, which correctly uses `"matcher": "Edit|Write|MultiEdit"`). Write tool calls never reach this hook at all.
+- **Scenario:** A maintainer trusting the header comment could assume Write calls already get the "target file exists" / "old_string ambiguous" checks and skip adding equivalent validation elsewhere. In practice they never do — and if the matcher were ever widened to include Write (per the comment's stated intent), check 1 ("block if target file doesn't exist") would fire on every brand-new-file Write call with the nonsensical message "Use Write tool to create new files" while blocking the very Write call in progress.
+- **Recommended direction:** Fix the header comment to say "Edit calls" (matching the real, sane scope), or explicitly note that Write is intentionally excluded because its checks (old_string presence) don't apply to file creation.

+- **Location:** `docs/frontmatter-reference.md:30`
+- **Status:** CONFIRMED · Verifier: Read the file directly: line 30 reads '\| `effort` \| string \| No \| Effort level for this agent: `low`, `medium`, `high` \|' while src/schemas/agent.ts:9 defines AgentEffort as z.enum(["low","medium","high","xhigh","max"]) and the Profile table two sections later (line 253) correctly lists all 5 with a
+- **Issue:** The Agent frontmatter table lists `effort` as accepting only `low`, `medium`, `high`, while src/schemas/agent.ts's AgentEffort enum (and the identical Profile-frontmatter table two sections later, which explicitly lists all 5 with an `effort: xhigh` example) both support `low|medium|high|xhigh|max`.
+- **Scenario:** An agent author reads the Agent table, concludes `xhigh`/`max` are invalid for `effort:` on an agent, and never sets `effort: xhigh` on e.g. a planner agent — even though CLAUDE.md's own "Effort & Context" section documents exactly this per-agent override pattern ("Per-agent: `effort` frontmatter") and the schema fully supports it.
+- **Recommended direction:** Update the Agent frontmatter table row to list all 5 values, matching the Profile table in the same document.

+#### M16 (medium) — skill-authoring.md sends authors to the wrong file/list for skill registration
+
+- **Location:** `docs/skill-authoring.md:91 vs src/lib/managed-skills.ts (ACTIVE_SKILLS/MANAGED_SKILLS) and src/lib/lint-skills.ts:14,201-226 (checkManaged uses ACTIVE_SKILLS)`
+- **Status:** CONFIRMED · Verifier: Verified directly: docs/skill-authoring.md:91 says 'Add "<name>" to MANAGED_SKILLS in src/setup.ts'. grep of src/setup.ts shows `import { MANAGED_SKILLS } from "./lib/managed-skills.ts"` — it is imported, not defined, there. managed-skills.ts defines `ACTIVE_SKILLS` (the currently-shipped list) and 
+- **Issue:** The "Registration" section says: "Add `"<name>"` to `MANAGED_SKILLS` in `src/setup.ts` (alphabetical order)." But `MANAGED_SKILLS` is no longer defined in src/setup.ts — it's imported from src/lib/managed-skills.ts as `[...ACTIVE_SKILLS, ...TOMBSTONE_SKILLS]`. Worse, lint-skills.ts's `checkManaged` invariant (the one CI actually enforces) checks against `ACTIVE_SKILLS` specifically, not the combined `MANAGED_SKILLS` — adding a new skill's name to `TOMBSTONE_SKILLS` instead (a plausible misreading of the stale doc, since both live in the same file) would still fail `managed-skills-missing`.
+- **Scenario:** A newcomer follows the doc literally: opens src/setup.ts looking for a `MANAGED_SKILLS` array to edit, doesn't find one (it's just an import), and either gives up or edits the wrong file/list, then gets a confusing `managed-skills-missing` CI failure that references a variable name (`ACTIVE_SKILLS`) never mentioned in the doc they just followed.

+#### M24 (medium) — docs/frontmatter-reference.md context-mode table omits the harvest skill and undercounts skills by one
+
+- **Location:** `docs/frontmatter-reference.md (fork-mode list) and its 'All Skills in cc-settings' table`
+- **Status:** CONFIRMED · Verifier: Verified by direct grep: `ls -d skills/*/ \| wc -l` = 37, skills/harvest/SKILL.md exists with `context: fork` in its frontmatter, and grepping 'harvest' against docs/frontmatter-reference.md returns zero hits. The fork-mode list (docs/frontmatter-reference.md, the 'Skills using fork (21)' line) enume
+- **Issue:** The "Context Modes" breakdown (fork 21 / main 5 / inherit 10 = 36) has zero occurrences of "harvest" (confirmed by grep), even though harvest/SKILL.md declares `context: fork`. This is repo-committed drift, not just install lag: it both undercounts (36 vs the true 37) and misclassifies harvest by silent omission.
+- **Scenario:** A maintainer or agent uses this table as the source of truth for which skills fork (e.g. to audit context isolation or the skill-count cap) and concludes there are 36 skills total with no fork-mode entry for harvest at all. The same drift class shows up in the user's installed ~/.claude/CLAUDE.md (version sentinel 12.0.0, predating harvest): it still says "36 cc-settings skills" with no harvest mention, while the repo's own CLAUDE-FULL.md, CLAUDE.md, and MANUAL.md all correctly say/list 37 -- the true count, independently confirmed via `ls -d skills/*/ | wc -l` (37), `ACTIVE_SKILLS.length` (37), and `bun run lint:skills` ("Linted 37 skill(s)").
+- **Recommended direction:** Add `harvest` to the fork-mode list in docs/frontmatter-reference.md and fix the counts to 22/5/10=37; separately, re-run setup.sh on the local install to pick up the current CLAUDE.md.
+
+#### L3 (low) — README.md states 36 skills; actual count and every other doc says 37
+
+- **Location:** `README.md:60`
+- **Status:** CONFIRMED · Verifier: Confirmed README.md:60 reads '# 36 auto-invocable skills'. Counted `ls -d skills/*/` = 37 directories (adversarial-audit through zero-tech-debt), matching MANUAL.md, CLAUDE.md, and CLAUDE-FULL.md's consistent '37' figure. Simple off-by-one, purely cosmetic.
+- **Issue:** README.md's 'What gets installed' tree annotates `skills/` as '# 36 auto-invocable skills'. Counting `ls skills/` gives 38 entries minus the non-skill README.md = 37 actual skill directories, matching the figure stated consistently in MANUAL.md ('All 37 headline skills', 'all 37 cc-settings skills'), CLAUDE.md ('37 cc-settings skills'), and CLAUDE-FULL.md ('We sit at 37 cc-settings skills').
+- **Scenario:** A reader cross-referencing README.md against MANUAL.md's skill count sees two different numbers (36 vs 37) for the same repo state and can't tell which is stale without counting the directory themselves.
+- **Recommended direction:** Update README.md line 60 to '37 auto-invocable skills'.
+
+#### L9 (low) — `requires:` (SkillRequirement) is schema-typed and in production use but entirely undocumented
+
+- **Location:** `docs/skill-authoring.md:44-50 (Optional frontmatter fields section, lists only agent/argument-hint) vs src/schemas/skill.ts:12-41 (SkillRequirement) and 4 shipped SKILL.md files`
+- **Status:** CONFIRMED · Verifier: Verified: docs/skill-authoring.md's 'Optional frontmatter fields' section (lines 46-49) lists only `agent:` and `argument-hint:` — no mention of `requires:`. grep confirms `requires:` is used in exactly 4 SKILL.md files: lighthouse, nuclear-review, qa, tldr. src/schemas/skill.ts defines SkillRequire
+- **Issue:** skill-authoring.md's "Optional frontmatter fields" section documents only `agent:` and `argument-hint:`. It never mentions `requires:`, even though SkillRequirement is a first-class typed schema field (with its own cross-shape guard for the command/mcp exclusivity rule) and is actively used by 4 shipped skills.
+- **Scenario:** A skill author wanting to declare a CLI or MCP prerequisite (so the installer warns about missing prereqs) has no documentation pointing them to `requires:` or explaining the command-vs-mcp exclusivity rule; they either omit the declaration (prereq check silently never runs for their skill) or guess at a shape that violates the `SkillRequirementShapeGuard` (e.g. declaring both `command` and `mcp`) and get an opaque schema error with no doc to cross-reference.
+- **Recommended direction:** Add a `requires` subsection to skill-authoring.md's Optional frontmatter fields, modeled on one of the 4 existing usages, documenting the command XOR mcp rule.
+
+#### L13 (low) — checkpoint's argument-hint omits the real 'show' subcommand
+
+- **Location:** `skills/checkpoint/SKILL.md:2`
+- **Status:** CONFIRMED · Verifier: Verified directly: skills/checkpoint/SKILL.md line 2 is exactly `argument-hint: "[save\|restore\|list\|clean] [name-or-id]"` with no `show`; line 29 of the same file has `### show [checkpoint-id]` documenting the subcommand; src/scripts/checkpoint.ts line 435 has `case "show":` implementing it. The hin
+- **Issue:** argument-hint: "[save|restore|list|clean] [name-or-id]" omits `show`, which is documented in the skill body ("### show [checkpoint-id]") and implemented in src/scripts/checkpoint.ts (`case "show":`).
+- **Scenario:** A user reads the slash-command hint text to discover available subcommands and never learns `show` exists, even though it's a real, working command for inspecting a checkpoint's contents before restoring it.
+- **Recommended direction:** Add `show` to the argument-hint: "[save|restore|show|list|clean] [name-or-id]".

+
+- **Location:** `src/setup.ts:565-568 (installDependencies)`
+- **Status:** CONFIRMED · Verifier: Verified src/setup.ts:555-568 (installDependencies): for profile !== 'light', unconditionally calls `if (!hasCommand('jq')) { const ok = await ensureSystemPackage('jq'); ... }` with no gating beyond the CC_SKIP_DEPS=1 test-only escape hatch (line 559). Traced ensureSystemPackage → runSilent in src/l
+- **Issue:** installDependencies unconditionally attempts `ensureSystemPackage("jq")` (which runs `brew install jq` / `sudo apt-get install -y jq` etc.) on every full-profile install when jq isn't already on PATH. A repo-wide grep shows no remaining `Bash.spawn`/shell invocation of jq anywhere in src/ — cli-preflight.ts's own jq entry says 'JSON parsing in shell snippets' but all hooks/scripts are TypeScript post the April 2026 bash→TS migration; the only other jq references are a comment and an install-hint mapping.
+- **Scenario:** A fresh Linux install with no jq on PATH silently shells out to `sudo apt-get update -qq && sudo apt-get install -y jq` during every `bash setup.sh` run (with stdin ignored, so a password-prompting sudo just fails fast) for a package nothing in the installed footprint actually invokes — wasted time/network on a clean CI box, and a confusing 'why does this need sudo' moment for a newcomer following MANUAL.md.
+- **Recommended direction:** Drop the forced jq install from installDependencies (leave it to the existing soft cli-preflight recommendation), or if some code path still genuinely needs it, name that call site in the JSDoc so the requirement doesn't look stale.
+
+## 4. Design tensions
+
+The five deepest structural issues. These are about the approach, not a line; the line findings above are mostly symptoms of these.
+
+### T1 — Block-level "user wins" merging cannot tell a user's edit from cc-settings' own stale output
+
+The single largest cluster of findings (H8, H9, M — array defaults, M — light-profile mixed groups, L — stripManagedSettings identity check) plus two previously-known warts (the hook-rename stale-audit flag, the nested-config-defaults gap) all reduce to one missing concept: **provenance**. The merger preserves whatever exists on disk, so anything cc-settings wrote yesterday becomes immovable "user customization" today. Every new managed surface (engine pins, nested defaults, renamed hooks) re-collides with this.
+**Alternative to weigh:** a per-key provenance manifest — at install time, record a hash of every value cc-settings writes (the hooks fingerprint already does exactly this for one block). On the next install: value matches our last write → ours, safe to update; value differs → genuinely user-edited, preserve. One mechanism retires the whole bug class and the hook-rename tombstone logic.
+
+### T2 — The supply-chain defense narrates a broader perimeter than it patrols
+
+SECURITY.md's threat model is settings.json tampering, but the fingerprint, the content-manifest audit, and iterCommandHooks all read only `settings.hooks` (H12). Meanwhile `env` (e.g. `ANTHROPIC_BASE_URL`, `apiKeyHelper`-adjacent vars), `permissions.allow`, and `mcpServers` are equally executable-by-consequence and unwatched — and the permission fragment itself allows wholesale `git push`/`checkout` with no deny counterparts (M) and leaves Edit/MultiEdit as a documented bypass of the Write deny on settings.json (M).
+**Alternative to weigh:** either extend the fingerprint to the full managed surface of settings.json (cheap: it is one more hash input), or shrink the claim — a scoped SECURITY.md that says exactly "hooks block only" is honest and ships today.
+
+### T3 — Capability contracts between skills/agents and their tools are enforced nowhere
+
+H2 (maestro's Team-less "Agent Teams Mode"), H13 (oracle compare needs AskUserQuestion its agent lacks), H14 (qa's Fresh-Eyes Gate needs a tool its own allowed-tools excludes), and the deslopper teardown step (M) are all the same defect: prose in a definition file promises a workflow; frontmatter denies the tools it needs; no linter compares the two. These fail only at runtime, in someone else's session, in a way the user reads as "the agent is being lazy".
+**Alternative to weigh:** a lint pass that extracts tool names referenced in the body of every skill/agent/profile and diffs them against the frontmatter grant. The repo already has six bespoke linters; this one would have caught 4 findings.
+
+### T4 — Hand-maintained doc tables are a second source of truth the repo already knows how to generate
+
+The docs area is the largest finding bucket (hooks-reference missing 4 live hooks, model table naming a nonexistent agent, three different skill counts, frontmatter-reference stale on models/effort/context-modes, MANUAL's phantom Setup event and phantom Sanity core server). The repo already solves this pattern for JSON Schema (`schemas:emit` from zod).
+**Alternative to weigh:** extend the emit step — hooks-reference's "Configured Hooks" table from `config/40-hooks.json`, the model-routing table from `agents/*.md` frontmatter, skill counts from `ls skills/`. Drift then becomes a CI failure, not an audit finding.
+
+### T5 — Sibling modules re-solve solved problems divergently
+
+Three secret-redaction functions with three different pattern sets (the weakest one guarding the most sensitive log), three kebab-case regexes, two "is this managed" checks, two exit-code conventions for the same CLI shape (checkpoint vs handoff), an inline re-implementation of the frontmatter regex next to the module that exports it. None is individually serious; together they mean every fix must be discovered N times.
+**Alternative to weigh:** a `src/lib/primitives/` layer (redaction, slug regex, managed-identity, CLI exit contract) with a lint rule against local re-implementations — the same consolidation move the skill library already went through in May.
+
+## 5. Open questions (maintainer input required)
+
+1. **Is `settings.json`'s `mcpServers` block a real surface or a vestige?** H9's fix direction depends on it: either the engine-mutated map must flow into both files, or `~/.claude.json` should be declared the single MCP source of truth and the settings.json block dropped from the merge. `docs/settings-reference.md` currently documents it as first-class.
+2. **Is the broad git allow-list a deliberate prompt-fatigue trade-off?** `Bash(git push:*)`, `git checkout:*`, `git branch:*` are allowed wholesale with no deny counterparts for their destructive forms. If that is an accepted risk, SECURITY.md should say so; if not, it is an M-severity gap to close.
+3. **What is the light tier's actual hook promise?** "No hooks except statusLine" (then the mixed-group strip must be surgical, per M finding) or "no *cc-settings* hooks" (then current behavior is close and the docs overstate)?
+4. **Is the upstream scanner meant to consult a live source?** Today `upstream:scan` diffs two hand-maintained local files; if the intent is real drift detection against Claude Code releases, it needs a network fetch; if offline-by-design, the docs oversell it.
+5. **Does anything still need the installer to provide `jq`?** No runtime hook shells out to it anymore, but team runbooks (including two team-knowledge notes) give `jq` one-liners as remediation steps. Keep-and-document, or drop the forced install?
+
+## 6. Refuted findings (for the record)
+
+Two raw findings did not survive adversarial verification and are excluded above:
+
+- *(security)* "SUSPICIOUS_PATTERNS never scans trailing args of managed hook commands" — refuted: `matchSuspicious(cmd)` runs first and unconditionally against the full command string.
+- *(skills)* "fix and ship implement diverging CI-fix procedures" — the textual asymmetry is real but the verifier traced both paths to the same effective behavior; kept out as not a defect.

 Non-interactive "user wins when declared" has one known tradeoff: if the team file changes a scalar like `model` in a future release, users whose `settings.json` still contains the previous value won't pick up the update (the merger can't distinguish "user explicitly declared X" from "X is a stale copy from last install"). Interactive mode surfaces each such divergence so you can opt into team updates explicitly.
 
+### Known limitation: array-valued defaults inside an already-present block don't propagate
+
+The scalar tradeoff above has an array-shaped sibling that's easy to miss: `deepMergeUserWins` recurses into plain objects (so a brand-new sub-key of an existing object block *does* reach existing installs — that's the fix for the general nested-default gap), but for any key whose value is an array on **both** sides, it treats the pair as a scalar conflict and keeps the user's array wholesale, with no per-element reconciliation.
+
+Concretely: `spinnerVerbs.verbs` (`config/10-core.json`) is an array default nested inside an already-present `spinnerVerbs` block. If a future release adds a new verb to that list, every existing install's on-disk `spinnerVerbs.verbs` — byte-identical to the *old* team default, never touched by the user — is indistinguishable from a deliberately customized array. The merger keeps the stale array; the new verb silently never reaches any pre-existing install. Unlike the object-sub-key case, there's no log line for this — only object-shaped new-default landings are counted via `defaultsAdded`.
+
+This is a real gap, not yet fixed — a proper fix needs either a stored previous-team-default snapshot (to detect "unchanged since last install" for arrays) or per-array `STRATEGIES` entries with explicit team-adds/user-can-decline semantics, mirroring how `permissions.allow` already reconciles arrays. Until then: **after any release that changes an array default nested in an existing block, verify with `bun run compose` (the fresh-install shape) and `jq` against a real `~/.claude/settings.json` (the re-install shape) rather than assuming re-install parity.** See the team-knowledge note `cc-settings-installer-skips-nested-config-defaults` for the original (object sub-key) class of this bug.

 ### What Gets Saved
 
-The handoff file includes:
-- **Current task**: What you're working on
-- **Progress**: What's been completed
-- **Decisions made**: Key choices and rationale
-- **Files modified**: List of changed files
-- **Next steps**: What remains to be done
-- **Context**: Important information to remember
-- **Learnings**: Patterns discovered in session
+Every handoff — auto or manual — always captures real, git-derived data at
+creation time:
+- **Project**: name, path, current branch
+- **Pending changes**: `git status --porcelain` (first 20 lines)
+- **Key files**: paths of files with uncommitted changes at save time
+- **Recent commits**: subjects of the last 3 commits
+- **Source**: `manual` or `auto` (see below)
+
+Beyond that, what's actually filled in depends on how the handoff was created:
+
+- **Manual** (`/handoff`, or `handoff.ts create --summary "text"`) — the
+  `--summary` text becomes the Session Summary. Active Todos / Current Task /
+  Notes for Next Session are placeholders (`<!-- ... -->`) for you (or the
+  agent, before the turn ends) to fill in manually — the CLI has no way to
+  know your in-progress todos, decisions, or learnings on its own.
+- **Automatic** (PreCompact/SessionEnd hooks call `create` with no
+  `--summary`, `source: "auto"`) — Session Summary, Active Todos, Current
+  Task, and Notes for Next Session all stay as unfilled placeholders. Only
+  the git-derived fields above are populated. Don't rely on an auto-handoff
+  alone to recall what you were doing — pair it with the structured
+  compaction template below, or run a manual `/handoff` with `--summary`
+  before ending a session.

+// Canonical secret redaction — the single place that decides what a
+// possibly-untrusted command string or subprocess-output string must never
+// leak in plaintext, before it's logged, cached to disk, or echoed to a
+// terminal/statusline.
+//
+// Before this module, the same job was duplicated (and diverged) in two
+// places: src/hooks/safety-net.ts's local `redactSecrets` (7 patterns:
+// sk-, ghp_, AKIA, Bearer, password=/token=/secret=) and src/lib/codex.ts's
+// `sanitizeOutput` (4 patterns: sk-, Bearer, Authorization:, *_API_KEY/
+// TOKEN/SECRET=). log-bash.ts — the HIGHER-exposure surface, since it logs
+// every Bash command, not just blocked ones — inherited the weaker of the
+// two. See M23 in docs/audits/codebase-audit-2026-07-08.md.
+//
+// This is the union of both pattern sets, plus: fine-grained GitHub PATs
+// (`github_pat_...`, GitHub's newer token format alongside the classic
+// `ghp_`/`gho_`/`ghu_`/`ghs_`/`ghr_` prefixes already covered).
+//
+// Ordering is load-bearing:
+//
+// - `sk-` runs FIRST so a value like `OPENAI_API_KEY=sk-...` gets its `sk-`
+//   suffix collapsed before the generic `=`-pattern (below) swallows the
+//   whole thing into one clean `OPENAI_API_KEY=[redacted]`, rather than
+//   leaving a nested `OPENAI_API_KEY=sk-[redacted]` fragment.
+// - The tight, `[^ &"]+`-bounded `password=`/`token=`/`secret=` patterns run
+//   BEFORE the broad, case-insensitive `*_API_KEY|TOKEN|SECRET=` pattern.
+//   The broad pattern's value-capture also stops at `&`/`"` (not just
+//   whitespace) for the same reason: a query string like
+//   `?token=abc&foo=bar` must only lose the token's value, not swallow the
+//   unrelated `foo=bar` alongside it — which a `\S+` capture would do since
+//   it doesn't stop at `&`.
+//   `token=`/`secret=` are deliberately case-SENSITIVE (lowercase only): the
+//   broad pattern already covers uppercase `TOKEN=`/`SECRET=` env-var forms
+//   case-insensitively, so a case-insensitive tight pattern here would
+//   re-match and mangle text the broad pattern already redacted correctly
+//   (e.g. `MY_TOKEN=[redacted]` would become `MY_token=[REDACTED]`).
+//   `password=` has no such collision (PASSWORD isn't in the broad
+//   pattern's alternation) so it stays case-insensitive for wider coverage.
+//
+// Do not reorder without re-checking tests/redact.test.ts and
+// tests/codex.test.ts's sanitizeOutput cases.

+## What
+
+A minimal, schema-valid knowledge note checked into the repo so CI's
+`lint:knowledge` step has real content to lint instead of running with no
+directory specified.
+
+## Why
+
+Without a fixture, the CI step only proved the script runs cleanly (it
+printed "no directory specified" and exited 0) — a regression in the actual
+linting logic (schema checks, name/filename mismatch, supersedes-unknown
+warning) would never be caught in CI.
+
+## How to apply
+
+Keep this note's frontmatter and filename stem in sync (`name` must equal
+`ci-lint-smoke-test`) so it keeps passing `lintKnowledgeDir` cleanly. Don't
+add real team knowledge here — this file exists only to give CI something
+to lint; real notes live in the team-knowledge repo.
