treatment(shipcheck): SHIP_GATE hard gates A-D pass (92%) + SECURITY/CHANGELOG/trust-model

Root shipcheck gate worked against the actual repo with evidence: 24 checked / 11 SKIP / 2 unchecked (both soft-gate E: translations + GitHub metadata — metadata now set via gh). Authored a real root SECURITY.md (per-surface threat model: local-only file I/O, no network/telemetry/secrets, destructive-op safety rails, fail-silent hook), a README '## Trust model' section (A2), root + packages/cli CHANGELOG (Keep-a-Changelog). Fixed D5: packages/cli tarball was missing CHANGELOG.md — added it to files (verified via npm pack --dry-run: dist + README + CHANGELOG + LICENSE). SCORECARD reflects actual audit counts. Hard gates A-D pass honestly; security spot-check (no secrets/network/telemetry/eval) confirmed.

+## [Unreleased]
+
+The consolidation of the Knowledge OS into a single npm-workspaces monorepo with one
+unified CLI. Three previously-separate packages and the live runtime hook now live and
+ship together under `loadout-os`.
+
+### Added
+
+- **Workspace monorepo** — `packages/{kernel,memories,rules,cli}` + `apps/hook` wired
+  under one npm-workspaces root, with an intentional topological build order
+  (kernel → memories → rules → cli) so the adapters build against the kernel's dist.
+- **Unified `@mcptoolshop/loadout-os` CLI** (`packages/cli`) — one binary that wraps the
+  three library surfaces (kernel = ai-loadout, memories, rules) and absorbs the
+  operational rituals:
+  - Namespaced adapter surfaces: `memories <index|validate|stats|health>` and
+    `rules <analyze|validate|stats|split>`.
+  - Flat kernel verbs: `resolve`, `explain`, `usage`, `dead`, `overlaps`, `budget`,
+    `validate` (the kernel index-structure validator — the flat-vs-namespaced split is
+    how the `validate` name collision is resolved).
+  - **`doctor`** — a read-only 8-check health screen over the live store, global index,
+    runtime-hook drift, resolver layers, core entries, observability loop, hook wiring,
+    and usage growth. Never writes.
+  - **`report`** — read-only observability over `usage.jsonl`: usage summary, dead
+    entries, token budget, and a score distribution for calibrating the hook floor.
+  - **`refresh`** — the Index Freshness Ritual (index → validate → publish) folded into
+    one command, with an andon halt on validation failure and a `<dest>.bak` compensator
+    on the one irreversible write.
+  - `hook test` — drive the runtime hook on a sample prompt in an isolated HOME.
+- **Runtime hook unified** (`apps/hook/loadout-hook.mjs`) — the `UserPromptSubmit` hook
+  that injects ≤5 pointer lines (≤200 tokens). Fail-silent: every error path exits `0`.
+- **Shared CLI substrate** — one arg parser, one structured `CliError { code, message,
+  hint }` shape routed at the process boundary (no raw stack traces), and per-command
+  `--help` with synopsis, arguments, flags, an example, and exit codes for every leaf
+  command.
+- **Documentation** — a Starlight handbook (overview, getting started, architecture,
+  command reference, rituals, migration) connected to the landing page, plus a root
+  `SECURITY.md` covering the consolidated attack surface.
+
+### Fixed
+
+- **Matcher recall** (FT-K1) — domain entries were scored by pure coverage
+  (`matched / declared keyword count`), which starved keyword-rich entries: a genuine
+  2–3 keyword match on the live 30+-keyword entries scored below the 0.1 inclusion floor.
+  The matcher now blends coverage with an absolute recall signal (`max(coverage,
+  matched / 5)`), so real multi-keyword matches are reachable while single incidental
+  hits stay quiet.
+
+### Changed
+
+- The three legacy bins (ai-loadout, claude-memories, claude-rules) keep working until
+  their planned retirement; the unified `loadout-os` package ships from this repo. The
+  published upstream today remains `@mcptoolshop/ai-loadout` (the kernel).

 Consolidation in progress. loadout-os folds together the kernel and two adapters that previously lived as separate packages, plus the live runtime hook. The published upstream today is **`@mcptoolshop/ai-loadout`** (the kernel); the unified `loadout-os` package ships from this repo. The three legacy bins keep working until their planned retirement.
 
+## Trust model
+
+loadout-os runs entirely on your machine. There is no network call, no telemetry, and no account.
+
+- **Data it touches (local only):** your memory store (`MEMORY.md` + topic files), your instruction files (`CLAUDE.md` + `.claude/rules/`), the generated dispatch index next to the store, the global resolver index (`~/.ai-loadout/index.json`), and the append-only usage log (`~/.ai-loadout/usage.jsonl`).
+- **Data it does NOT touch:** no network egress, no telemetry, no remote services, no credentials or secrets. Nothing is read, stored, or transmitted off the local disk paths above.
+- **Permissions required:** local filesystem only. `doctor` and `report` are pure reads (they never write). The only writes are the index files, the interactive `rules split` output, and the usage log — all in the expected local locations above. The irreversible write (`refresh` publishing the live global index) is guarded by an andon halt on validation failure and a `<dest>.bak` compensator. The runtime hook is fail-silent: every error path exits `0`, so it can never block a prompt.

+
+Counts are: **checked** (evidence-backed `[x]`) / **applicable** (items that are not `SKIP`). SKIPs are not-applicable items (MCP/pypi/vsix/desktop/vscode) or explicit studio-policy skips.
+
+| Category | Checked / Applicable | SKIP | Coordinator / publish-time | Status |

+| E. Identity (soft) | 2 / 4 | — | 2 (translations, GitHub metadata) | partial (soft) |
+
+**Hard gates A–D: all applicable items checked or SKIPped honestly → PASS.**
+
+## Key gaps closed this pass
+
+1. **Root SECURITY.md** was a template — now a real per-surface threat model (pure core, read-only rituals, write path with andon halt + `.bak` compensator, fail-silent hook; no network/telemetry/secrets; matcher uses plain-string lookups, no user regex → no ReDoS, no eval).
+2. **README threat model** — added a "Trust model" section (data touched / not touched / permissions).
+3. **Root CHANGELOG.md** — was a template stub; now Keep-a-Changelog with an `[Unreleased]` consolidation summary (workspace wiring, unified CLI + doctor/report/refresh, matcher recall fix, docs).
+4. **D5 npm pack** — `packages/cli` tarball was missing CHANGELOG.md; added `packages/cli/CHANGELOG.md` and `CHANGELOG.md` to the cli `files` field. Verified the tarball now ships dist/ + README.md + CHANGELOG.md + LICENSE.
+
+## Remaining (coordinator / publish-time)
+
+| Item | Owner | When |
+|------|-------|------|
+| E2 Translations (polyglot-mcp, 8 languages) | Coordinator | BEFORE npm publish + GitHub release |
+| E4 GitHub repo metadata (description, homepage, topics) | Coordinator (`gh repo edit`) | Publish time |
+| D2 actual version-matches-tag | Coordinator | Phase-6 bump to 1.0.0 + tag `v1.0.0` (enforcement gate already in release.yml) |
+
+## Notes
+
+- Version is the placeholder `0.0.0` in both `package.json` and `packages/cli/package.json`; the coordinator bumps to `1.0.0` at Phase 6 (per shipcheck product standards: pre-1.0 promotes straight to 1.0.0). The `release.yml` tag-vs-version check enforces the match at tag time.
+- The first real `npm publish` is blocked until the workspace deps (`@mcptoolshop/claude-memories`, `@mcptoolshop/claude-rules`) are published or bundled — see the NOTE in `release.yml:65-69` and the multi-repo-publish-sequencing protocol. This is a release-sequencing concern, not a SHIP_GATE item.

+## Attack Surface
+
+`loadout-os` is a **local-only CLI** (`@mcptoolshop/loadout-os`) plus a `UserPromptSubmit` runtime hook. It unifies three previously-separate library surfaces and absorbs the operational rituals. The surface breaks into four parts:
+
+- **Pure core (kernel).** Matching, merging, validation, token estimation, and frontmatter parsing are pure functions with no side effects — they only transform data structures in memory. The matcher (`packages/kernel/src/match.ts`) scores entries with plain-string keyword/token lookups (`Set.has`, `split`, `every`/`some` — `match.ts:105-119`). There is **no user-supplied regex** in the matching path, so there is no ReDoS vector; the only `RegExp` use is a fixed `[^a-z0-9\s]` tokenizer (`match.ts:73`).
+- **Read-only rituals (`doctor`, `report`).** Both are pure reads — they never write (`doctor.ts` header + `runDoctor` comment "Pure read — no writes, ever", `doctor.ts:128-131`; `report.ts` header "Pure read; never writes"). They read the canonical memory store, the global resolver index, `settings.json`, and `usage.jsonl` from fixed, well-known locations, and delegate every check to a library validator rather than self-grading.
+- **Write path (`refresh`, `memories index`, `rules split`).** The only writes are **local files in expected locations**: the store `index.json` (next to `MEMORY.md`), the global resolver index (`~/.ai-loadout/index.json`), and — for `rules split` — `.claude/rules/` plus the `CLAUDE.md` file itself. Destructive operations have safety rails:
+  - **`refresh`** is the one ritual that performs an irreversible write (the live global index the hook reads on every prompt). It has an **andon halt** — any error-severity validation issue exits `1` and writes nothing downstream (`refresh.ts:211-219`) — and a **named compensator** — an existing destination is backed up to `<dest>.bak` before overwrite and restored on any write failure (`refresh.ts:253-287`). `--dry-run` computes everything and writes nothing.
+  - **`rules split`** is interactive: it passes through to the `claude-rules` bin with inherited stdio, requires per-extraction confirmation, supports `--dry-run`, and writes a `.bak` backup before editing. loadout-os spawns it with `spawnSync` and forwards the user's args verbatim (`commands.ts:411-433`) — this is the only subprocess spawn and it targets a fixed, resolved local bin, never an arbitrary command.
+- **Runtime hook (`apps/hook/loadout-hook.mjs`).** A `UserPromptSubmit` hook that reads the global index, matches the prompt, and injects ≤5 pointer lines (≤200 tokens). It is **fail-silent by design**: every error path exits `0` (`safeExit(0)` on missing index, non-JSON stdin, empty prompt, malformed index, import failure, or a matcher throw — `loadout-hook.mjs:72-95`), so a broken hook can never block a prompt. Its only write is an append-only `usage.jsonl` event, wrapped in a `try/catch` that swallows failures (`loadout-hook.mjs:120-141`).
+
+## Across all surfaces
+
+- **No network access** — makes no HTTP requests, opens no sockets, follows no remote locations.
+- **No telemetry** — nothing is collected centrally or transmitted. Usage data stays in the local `~/.ai-loadout/usage.jsonl` the operator owns.
+- **No secrets handling** — reads no credentials, environment secrets, or tokens; the tool handles loadout metadata only. No tokens or credentials appear in source or in any diagnostic output.
+- **No code execution from data** — no `eval`, no `Function()`, no dynamic execution of file content. On-disk index/usage files are treated as untrusted: malformed JSON layers and malformed JSONL lines are skipped rather than executed or thrown on.
+- **Scoped filesystem access** — writes are confined to the store `index.json`, the global resolver index, `.claude/rules/` + `CLAUDE.md` (via the interactive split), and the append-only usage log. The tool never walks arbitrary trees or writes outside the paths described above.
+
+## Input Validation
+
+- Frontmatter and `MEMORY.md`/`CLAUDE.md` parsing uses hand-rolled string splitting — no YAML parser, no regex-based evaluation, no prototype-pollution vector (inherited from the kernel/memories/rules adapters; see their per-package `SECURITY.md`).
+- `validateIndex()` / `validateMemory()` check structural integrity only; they do not execute or interpret field values.
+- The shared CLI arg parser fails loudly on a swallowed flag value (`--out --json`) rather than silently creating a file named `--json` (`console.ts:76-93`).
