-- Hooks: `hooks/` — `inject.py` (injects `ORCHESTRATION.md` as additionalContext to all sessions)
-- Behavior: SessionStart hook injects an `ORCHESTRATION.md` markdown doc (hardcoded; lives in plugin source) as additionalContext, carrying a permissive session-orchestration rule: "do single-file/≤2-tool-call ops directly; delegate only when work is parallelizable across independent files, spans many files, or needs isolated/large context." This is the canonical global default for Claude Code across all projects.
-- Migration: migrated from a standalone repo (`~/dev/cc-plugins/orchestration/`, 2026-07-03) and integrated into cc-os. Supersedes the per-project copy-pasted orchestration text blocks that previously existed in individual project CLAUDE.md files (including a stricter local override that cc-os had carried — now removed; see ADR-019).

-- Hooks: `hooks/hooks.json` → SessionStart hook (matcher: startup|resume) runs `scripts/reminder.py` via `${CLAUDE_PLUGIN_ROOT}` (5s timeout), emitting a deterministic zero-token reminder banner
-- Behavior: Monitors stale and bloated project documentation per-project under `.dochygiene/` state dir (gitignored). SessionStart reminder is deterministic (no AI tokens, once/day snooze). Skills (verb-first, no `commands/` dispatcher — invoked directly as `/os-doc-hygiene:<skill>`, per [[cc-os-plugin-skill-naming-convention]]): `check` (AI-assisted classification of staleness signals, emits machine+human reports), `clean` (AI-assisted or deterministic patch application with git-safe scoped cleanup), `status` (read-only lifecycle-timestamp read), `sweep` (check then clean in sequence). Reversion-protected via invariants.md + golden-example test fixtures.
-- Migration: migrated from standalone repo (`~/dev/cc-plugins/doc-hygiene/`, 2026-07-03) and integrated into cc-os. No content conflicts detected (doc-hygiene scope does not overlap cc-os memory system). Renamed from `doc-hygiene` to `os-doc-hygiene` per cc-os plugin naming convention. Skills renamed `hygiene-check`/`hygiene-clean` → `check`/`clean`, and the `commands/hygiene.md` dispatcher removed in favor of two new skills (`status`, `sweep`), aligning with the `os-vault`/`os-orchestration` pattern of no `commands/` directory (2026-07-03).

-**Plugin renamed `memory` → `os-vault` (2026-07-03):** directory renamed in git, `~/.claude/plugins/os-vault` symlink and `settings.json`'s `enabledPlugins` updated — but the `local-plugins` marketplace manifest (`~/.claude/plugins/.claude-plugin/marketplace.json`) still declared the old `memory`/`./memory` entry, and `installed_plugins.json` still had a cached `memory@local-plugins` install record. Skills (and therefore slash commands) never registered under the new name as a result; hooks kept working because they're wired by absolute path in `settings.json`, independent of plugin resolution. Fixed by editing the marketplace manifest to `"os-vault"`/`"./os-vault"`, then `claude plugin marketplace update local-plugins`, `claude plugin install os-vault@local-plugins`, `claude plugin uninstall memory@local-plugins`. See ADR-018 and the "Renaming or moving a local plugin" procedure below.
-
-### Renaming or moving a local plugin
-
-Renaming a plugin directory under a directory-source marketplace (like `local-plugins`, whose
-source is `~/.claude/plugins` itself) requires updating **three** places, not just the directory
-and `settings.json`:
-
-1. **Plugin directory / symlink** — the actual files (or symlink target, for plugins that live in
-   a git repo like `cc-os/plugins/os-vault/`).
-2. **Marketplace manifest** — `~/.claude/plugins/.claude-plugin/marketplace.json` (for
-   `local-plugins`) lists each plugin's `name` and `source` path explicitly; this does **not**
-   auto-discover from the directory listing. Update the entry to match the new name/path.
-3. **`settings.json` `enabledPlugins`** — the `<name>@<marketplace>` key must match the manifest
-   entry from step 2.
-
-Then refresh the plugin manager's state so it re-resolves the marketplace and drops the stale
-install record:
-
-```bash
-claude plugin marketplace update <marketplace-name>   # re-validates the manifest
-claude plugin install <new-name>@<marketplace-name>    # creates the new install record
-claude plugin uninstall <old-name>@<marketplace-name>  # drops the stale one
-claude plugin list                                     # verify: new name enabled, old name gone
-claude plugin details <new-name>@<marketplace-name>     # verify skills/agents/hooks resolved
-```
-
-Skipping step 2 is the failure mode to watch for: hooks (wired by absolute path in
-`settings.json`) keep working, masking the fact that skills/slash-commands silently stopped
-registering under the plugin's new name.

The ignore list is generated per-project — what counts as noise varies by stack — not from a static template.
 - **Rationale**: graphify's `.gitignore` blindness is by design; the correct lever is `.graphifyignore`, not a workaround. Assessment before extraction surfaces borderline dirs (migrations, seeds, fixtures, sample data) that need a human call. Per-project generation avoids the false safety of a shared template that silently mismatches a new stack.
 - **Alternatives rejected**: **Static `.graphifyignore` template** — rejected; dependency/build/cache dirs vary by project stack; a template would both over-exclude (suppressing wanted source) and under-exclude (missing stack-specific dirs) for any given project. **Auto-write without user confirmation** — rejected; borderline directories (e.g. migrations, seeds, fixtures) require human judgment; mechanical exclusion would silently drop legitimate content. **AST-only mode (skip doc pass entirely)** — deferred; the `--backend ollama` flag stays; the ignore list is the correct cost lever, not backend switching.

 - **Default-exclude taxonomy is type-based, not name-based.** The skill's assessment step organizes exclude candidates into 11 categories by KIND (fetched deps, build/generated output, caches, VCS internals, editor/AI-tooling dirs, lockfiles, coverage/logs, bulk data/databases, binaries, secrets, graphify-out/) with a meta-principle: index what a human authored; exclude anything fetched, generated, cached, tooling config, bulk data/binary, or secret. Example names within each category are illustrative, not exhaustive — the goal is to recognize the kind even in an unfamiliar stack. See SKILL.md for the full table.
 - **Onboarding uses the 16k-context model.** The `graphify extract` command now passes `--model qwen25-coder-7b-16k` (the `ollama_model` from config.yaml), a 16k-context build of qwen2.5-coder:7b. Inference is GPU-bound (~65 tok/s); the main speed lever is chunk-count × generation — fewer chunks per doc via a larger context window. `GRAPHIFY_OLLAMA_NUM_CTX` does not propagate through graphify's OpenAI-compatible endpoint; the larger context must come from the model's Modelfile.
 
-## ADR-018 — Plugin renames must update the marketplace manifest, not just the directory and settings.json
-
-_Date: 2026-07-03_
-
-- **Context**: The `memory` plugin directory was renamed to `os-vault` (git rename,
-  `plugins/memory/` → `plugins/os-vault/`), the `~/.claude/plugins/os-vault` symlink was
-  updated, and `settings.json`'s `enabledPlugins` was flipped to `os-vault@local-plugins`.
-  Despite this, no `os-vault` slash commands (skills) were available in-session. Root cause:
-  the `local-plugins` marketplace manifest (`~/.claude/plugins/.claude-plugin/marketplace.json`)
-  — which explicitly lists each plugin's `name`/`source` rather than auto-discovering the
-  directory — still declared only `memory`/`./memory`, and `installed_plugins.json` still held
-  a stale install record for `memory@local-plugins`. Hooks kept firing throughout (they're
-  wired by absolute path directly in `settings.json`, bypassing plugin resolution entirely),
-  which masked the break — everything looked healthy except the skills/slash-commands.
-- **Decision**: A local-plugin rename/move is a three-file operation: (1) the plugin directory
-  or symlink, (2) the marketplace manifest entry (`name` + `source`), (3) `settings.json`
-  `enabledPlugins`. After all three, run `claude plugin marketplace update <marketplace>` to
-  re-validate, `claude plugin install <new>@<marketplace>` to create the new install record,
-  and `claude plugin uninstall <old>@<marketplace>` to drop the stale one — then verify with
-  `claude plugin list` and `claude plugin details <new>@<marketplace>` (skills/agents/hooks
-  inventory). Documented as a standing procedure in `CLAUDE.md` under "Renaming or moving a
-  local plugin."
-- **Rationale**: The marketplace manifest is the actual source of truth for what plugins exist
-  under a directory-source marketplace — the directory listing itself is not consulted for
-  plugin identity. Because hooks are independently wired by path, they give a false signal that
-  the plugin is fully operational; skill/slash-command registration must be checked separately
-  via `claude plugin details`.
-- **Alternatives rejected**: **Rely on directory listing / auto-discovery** — not how
-  `local-plugins` (a directory-source marketplace) resolves plugins; the manifest is
-  authoritative. **Skip the install/uninstall refresh, just fix the manifest** — leaves a stale
-  cached install record in `installed_plugins.json` under the old name, which is confusing and
-  can mask a future rename of the same kind.
-- **Consequences / ongoing contracts**: any future rename of `os-vault` (or a new local plugin)
-  must touch the marketplace manifest, not just `settings.json`. `claude plugin details
-  <plugin>@<marketplace>` is the verification step to run after any plugin registration change
-  — it surfaces the skill/agent/hook inventory that a passing hook test would not.
-- **Status**: Accepted 2026-07-03. Fixed and verified same day (`os-vault@local-plugins` shows
-  enabled with 5 skills resolved; stale `memory@local-plugins` record removed).

-## ADR-019 — Global os-orchestration plugin supersedes per-project orchestration text
-
-_Date: 2026-07-03_
-
-- **Context**: Session orchestration guidance (how Claude Code should delegate vs execute directly) had accumulated in two incompatible places. (1) A permissive global plugin (`os-orchestration`, moved into cc-os from a standalone `~/dev/cc-plugins/orchestration/` repo) injects `ORCHESTRATION.md` as SessionStart additionalContext carrying the rule: "do single-file/≤2-tool-call ops directly; delegate only when work is parallelizable across independent files, spans many files, or needs isolated/large context." (2) cc-os's own `CLAUDE.md` carried a stricter per-project override: "Delegate all file I/O and shell commands to subagents via the Agent tool. No exceptions by default." The two rules contradicted each other and lived in different places, creating confusion about which one applies when.
-- **Decision**: **Adopt the plugin's permissive rule as the canonical global default.** cc-os relinquishes its stricter local override entirely. Every project now follows the plugin's behavior: single-file/≤2-tool-call ops are executed directly; larger or cross-file work is delegated. The `os-orchestration` plugin is migrated into cc-os (`plugins/os-orchestration/`) following the same pattern as `os-vault` (git-tracked, symlinked into `~/.claude/plugins/`, registered via `local-plugins` marketplace).
-- **Rationale**: One authoritative orchestration rule, maintained in one place (the plugin, under version control), is simpler than per-project copy-paste text that drifts. The permissive rule reflects actual practice (small direct edits are efficient; large multi-file refactors warrant delegation). Consolidation into a global plugin means all projects get the same behavior without duplication, and the rule can be evolved once and picked up everywhere.
-- **Alternatives rejected**:
-  - **Keep cc-os's stricter override as a local addition on top of the global plugin**: would recreate the incompatibility problem; cc-os would be a special case instead of a normal project.
-  - **Make the strict version the global default instead**: reverses the decision in favor of the permissive rule. The permissive approach scales better (most tasks fit the single-file/≤2-tool threshold); strict delegation adds ceremony for no gain on small work. The plugin's default was chosen by the user for good reason.
-- **Cross-references**: ADR-016 (os-vault plugin sourced from cc-os git repo, establishing the git-tracked plugin pattern), ADR-018 (plugin marketplace mechanics for local plugins).
-- **Status**: Accepted 2026-07-03. cc-os's CLAUDE.md updated to remove the stricter orchestration section and note that behavior is now global; `os-orchestration` component added to Implemented Components.

-
-Claude Code plugin that monitors and manages **stale** and **bloated** project
-documentation. Installed globally, operates per-project. Reminds (deterministic,
-zero-token) on `SessionStart`; checks and cleans on demand via skills.
-
-> Read `PRD.md` first — it is the source of truth for scope, decisions, and
-> rationale. This file is the build map.
-
-## Core distinction (do not conflate)
-
-- **Stale** = the doc is *wrong* (contradicted, orphaned, superseded,
-  provisional, completed-in-place, duplicated). Remedy: fix or remove.
-- **Bloat** = the doc is *true but mostly irrelevant* (distill, split, freeze).
-  Remedy: change its altitude, almost never delete history.
-
-Severity scales with **injection frequency** — a stale line in `CLAUDE.md` (auto
--injected every session) is worse than the same line in a doc nobody opens.
-
-## Design invariants (see PRD + reversion-protection pattern)
-
-1. The `SessionStart` hook **only reminds** — it never runs analysis or mutates
-   anything, and spends no AI tokens. All mutation is user-invoked.
-2. Reminder **snoozes** (≤ once/day while stale) via `last_reminded`.
-3. State lives **in-project** under gitignored `.dochygiene/`. No global index.
-4. **Report rollover**: keep only the latest report. The tool must not become
-   the bloat it polices.
-5. Cleanup is **git-safe**: clean/committed tree required (or auto WIP
-   checkpoint), each run is one reviewable commit.
-6. **Deterministic-first**: scan/state/patch-apply/token-estimate are scripts
-   (no model). AI does only classification and prose distillation.
-7. **Safety tiers**: `auto` (deterministic+reversible+objective) runs without
-   prompt; `confirm` (destructive/subjective/generative) escalates for approval.
-8. **mtime guard**: never apply a cached edit to a file changed since the check.
-9. Frozen/ignored files (`hygiene: frozen` frontmatter, `.dochygiene-ignore`,
-   append-only logs) are never flagged.
-
-Changing any invariant requires updating `invariants.md` and the golden
-examples, with explicit human approval.
-
-## Build order (report schema gates everything)
-
-1. **Machine report schema** — the contract every component consumes. Freeze
-   first. (per-file: category, signals, op, op-type, safety tier, optional
-   exact-edit, token estimate.)
-2. **Deterministic core** — *build-spike #1 first*: a trivial `hooks/hooks.json`
-   emitting a `systemMessage` banner on `SessionStart`, confirmed to render
-   visibly in a real session (no plugin in this collection wires a CC hook yet).
-   Then: scanner (signals + shortlist), state store (timestamps, rollover,
-   snooze, atomic writes, project-root resolution), reminder hook
-   (`SessionStart`, `matcher: startup|resume`, injected-clock testable).
-3. **`check` skill** — scanner shortlist → AI classify (Sonnet, judgment only) →
-   **`report_builder.py`** deterministic finalize pass → human + machine reports →
-   update `last_check`. The finalize pass sits **between** model classification and
-   the report write (invariants #6, #10): it computes `expected_sha256`, looks up
-   `is_destructive`/`is_reversible` from `exact_edit.kind`, derives `safety_tier`
-   via `validate_report.py`'s single-source `derive_safety_tier(...)`, sources
-   `raw_tokens` from the token estimator, and assembles the schema-valid machine
-   report + human-report skeleton. The model authors none of those four fields.
-4. **`clean` skill + patch-applier** — consume report, mtime-guard, apply
-   `deterministic` ops mechanically, delegate `generative` to Sonnet, gate
-   `confirm`, git checkpoint + single commit, scopable by category/file →
-   update `last_clean`. Then **`sweep`** = check-then-clean.
-   - **RESOLVED (Phase 4):** `insert-frontmatter` ops have `has_anchor=False` and
-     carry **no** `expected_sha256`, so invariant #8's content hash cannot protect
-     them. The applier re-derives frontmatter freshness at apply time: re-read the
-     file, parse frontmatter; key present with target value → idempotent no-op; key
-     present with different value → skip (`frontmatter-key-conflict`); key absent →
-     insert. No cached hash is trusted. This resolves the deferred hole noted in
-     `add-check`.
-5. **Bonus (v2)** — deterministic patch-apply hardening + token estimator
-   (local tokenizer, injection-frequency weighting, bottom-up rollup).

-- **Scripts**: structured JSON output, correct exit codes, idempotent, testable

-## THE GATE (task 1.2) — do this first on resume
-
-Task 1.2 requires a human to start a real Claude Code session and **visually confirm** the spike banner renders. Everything downstream (1.3 → Group 4 → Group 5) is gated on it. The enable path is ALREADY fully set up — do NOT re-derive it:
-
-- The plugin `doc-hygiene@cc-plugins` is **already installed, enabled, and cached**. (`enabledPlugins."doc-hygiene@cc-plugins": true` in `~/.claude/settings.json`; marketplace registered under `extraKnownMarketplaces.cc-plugins` → directory `/home/jared/dev/cc-plugins`.)
-- There is **no `/install` slash command** in this build (v2.1.181) — plugin management is the `claude plugin ...` CLI, already run.
-- CC loads hooks from the cache snapshot `~/.claude/plugins/cache/cc-plugins/doc-hygiene/0.0.1/hooks/hooks.json`, which is **byte-identical to source**. If `hooks/hooks.json` is edited later, run `claude plugin update doc-hygiene@cc-plugins` to re-snapshot before testing.
-- The `systemMessage` banner mechanism is **proven** in this build — memsearch's SessionStart banner renders the same way.
-
-**To confirm:** start a fresh Claude Code session (any directory; plugin is user-scoped) and look for, alongside the memsearch line:
-
-    [doc-hygiene] Documentation health reminder is active. Run /os-doc-hygiene:check to scan for stale or bloated docs.
-
-- **Renders** → check task 1.2, then do task 1.3 (record the confirmed format: plugin-root `hooks/hooks.json`, top-level `hooks` key, per-matcher nested `hooks` array, `systemMessage` field, `matcher: startup|resume`, `timeout: 5`). Then build Group 4, then Group 5.
-- **Blank** → the hooks.json format or loading is wrong for this build; debug BEFORE Group 4 inherits the format. (Format currently mirrors the canonical corrected shape from commit `4d595a9`, avoiding the 3 prior hook-format bugs.)
-
-## Group 4 build notes (when unblocked)
-
-- 4.1: `Reminder` decision PURE over `(last_check, last_reminded, now, threshold)` per design D5 — silent when fresh; banner when stale and not snoozed; snooze keyed on **calendar day** via `last_reminded`.
-- 4.2: reminder script reads state via the Group 3 `StateStore` (already built) with an injected clock; on banner emit `systemMessage` naming the slash command + write `last_reminded = now`; on silent write nothing; always exit 0; missing/unreadable state = never-checked (stale). No scan, no model (invariant #1).
-- 4.3: update `hooks/hooks.json` to invoke the reminder script (reuse confirmed format from 1.3), `timeout` ≤ 5s. This REPLACES the spike's fixed banner.
-- 4.4: tests with injected clock (invariants #1, #2): fresh→silent; stale+never→banner; stale+reminded-same-day→silent; stale+reminded-prior-day→banner; assert only `last_reminded` mutated, only on banner.
-- Build Group 4 with **Sonnet** (real systems Python), not Haiku.
-
-## Open decision for the user (flag, not yet resolved)
-
-Scanner deviation (tasks 2.2/2.3): the implementer read design **D7** as placing *append-only* in the **exclusion pipeline only**, NOT as a per-path signal (an append-only file is excluded before signals run, so an `append_only_growth` signal would be self-contradictory). The dead signal was removed. The spec's signal list mentioned "append-only growth" only as an illustrative "for example." **Confirm this reading is acceptable**, or restore append-only as a signal.
-
-## Conventions for the resuming session
-
-- Orchestrator-subagent pattern (project CLAUDE.md): delegate via Agent tool; do NOT call Read/Write/Bash/Grep/Glob/Edit directly. Model routing: scripts=no model (author with Sonnet for real logic), classification=Sonnet, orchestration=Opus.
-- Each parallel agent owns disjoint files; serialize `tasks.md` checkbox edits in the orchestrator to avoid write races.
-- Do NOT push commits. Do NOT commit `map-driven-planning/docs/`.
-- Changing any invariant requires `invariants.md` + golden-examples update + explicit human META-RULE approval. (Known pre-existing: `invariants.md` #2 "Why" prose still has stale `clear`/`compact` wording — behavior is correct; prose fix is META-RULE-gated and untouched.)

-## Problem Statement
-
-When I work intensively in a project, documentation accumulates two distinct
-defects that both degrade how usefully an AI agent (and I) can read the repo:
-
-- **Stale docs** — content that is now *wrong*: it contradicts the running
-  system, references files/symbols/paths that no longer exist, is pinned to an
-  old tool version, claims "in progress" for shipped work, or duplicates a fact
-  that has since drifted. Trusting it causes wrong actions. This is the
-  high-severity class because agents read confidently and don't sanity-check.
-- **Bloated docs** — content that is still *true* but mostly irrelevant: long
-  debugging narratives, resolved-problem detail at full fidelity, decisions
-  recorded without distillation, append-only growth. It doesn't lie; it dilutes
-  attention and burns context-window budget, and buries the one live caveat in
-  archaeology.
-
-Severity scales with **injection frequency**: a stale line in a doc nobody opens
-is annoying; the same line in an auto-injected file (`CLAUDE.md`, memory index)
-misleads *every* session unprompted.
-
-Today I notice this only incidentally, have no systematic way to find it across
-projects, and cleaning it up by hand wastes both my time and AI tokens. I also
-don't want a tool that interrupts my flow or silently rewrites my repos.
-
-## Solution
-
-A Claude Code plugin, installed globally but operating per-project, that:
-
-1. **Reminds, doesn't nag.** A deterministic `SessionStart` hook checks an
-   in-project timestamp and, only if the last hygiene check is older than a
-   threshold, injects a noticeable reminder telling me how many days it's been
-   and which command to run. Zero AI tokens unless I act. Snoozes so it reminds
-   at most once per day while stale.
-2. **Checks on demand.** A `check` skill runs a **deterministic scan** that
-   gathers objective signals and a candidate shortlist, then an **AI
-   classification pass** that reads candidates, categorizes them (stale vs
-   bloat, by sub-type), assigns each a concrete operation tagged by
-   *op-type* (`deterministic` | `generative`) and *safety tier* (`auto` |
-   `confirm`), and estimates context-weight savings. It produces a **human
-   report** (what to clean and why) and a **machine report** (structured ops
-   for the cleaner to consume).
-3. **Cleans, git-safely and scoped.** A `clean` skill consumes the machine
-   report. For each op it checks an **mtime guard** (file unchanged since the
-   check); `deterministic` ops are applied mechanically with no model;
-   `generative` ops are delegated to Sonnet subagents. `auto`-tier ops run
-   without fuss; `confirm`-tier ops escalate into an approval list. Cleanup runs
-   only on a clean/committed tree (or after an auto-checkpoint) and lands as a
-   single reviewable commit. The user can scope a run to specific categories or
-   files.
-4. **Composes.** A `sweep` entry runs check-then-clean in one go, still
-   surfacing the report and gating `confirm`-tier ops.
-
-The design leads with deterministic code (scan, signals, state, patch-apply,
-token estimate) and reserves AI for the genuine judgment (classification and
-prose distillation). This keeps it fast, cheap, and trustworthy.
-
-## User Stories
-
-1. As a developer, I want a deterministic `SessionStart` reminder when a
-   project's docs haven't been checked in over a threshold, so that I'm nudged
-   without spending any AI tokens.
-2. As a developer, I want the reminder to be visually noticeable and to name the
-   exact command to run, so that acting on it is one step.
-3. As a developer, I want the reminder to snooze (at most once/day while stale),
-   so that it doesn't nag me every session for a week.
-4. As a developer, I want hygiene state stored per-project in a gitignored dot
-   directory, so that there is no global index to corrupt, race, or itself go
-   stale.
-5. As a developer, I want to run a check manually with a slash command, so that
-   after a heavy context-building session I can clear what accumulated.
-6. As a developer, I want the check to deterministically scan scoped files and
-   compute objective signals (broken references, version skew, edit-recency vs
-   git churn, location, append-only growth, archive-to-live ratio, frontmatter
-   markers), so that the AI pass starts from facts, not a blank read.
-7. As a developer, I want the AI pass to classify each candidate as stale
-   (contradicted, orphaned, superseded, provisional, completed-in-place, duplicated) or
-   bloat (distill, split, freeze), so that the right remedy is chosen per file.
-8. As a developer, I want each recommended operation tagged with an op-type
-   (`deterministic` | `generative`) and a safety tier (`auto` | `confirm`), so
-   that the cleaner knows what it can apply mechanically and what needs a model
-   or my approval.
-9. As a developer, I want a human-readable report describing what should be
-   cleaned and *why*, grouped by category, so that I can decide at a glance.
-10. As a developer, I want a machine-readable report the cleaner consumes
-    directly, so that the cleanup step doesn't re-derive the analysis.
-11. As a developer, I want only the single most-recent report kept (rollover
-    deletes prior reports), so that the tool's own artifacts don't become bloat.
-12. As a developer, I want the check to estimate context-weight savings per
-    file, summed into categories and a total (bottom-up), so that I can
-    prioritize.
-13. As a developer, I want savings honestly framed and weighted by injection
-    frequency (auto-injected files counted as real per-session savings,
-    on-demand docs as theoretical-max), so that the numbers aren't misleading.
-14. As a developer, I want the cleaner to apply `deterministic`+`auto` ops
-    (move-to-archive, freeze-stamp, known-target link fix, exact-dup dedupe)
-    with no model and no prompt, so that no-brainer cleanup just happens.
-15. As a developer, I want every destructive, subjective, or generative op to be
-    `confirm`-tier and escalated for my approval, so that nothing surprising
-    happens to my repos.
-16. As a developer, I want a per-op mtime guard so that if a file changed since
-    the check, its cached edit is skipped (and re-analysis recommended) rather
-    than blindly applied.
-17. As a developer, I want generative cleanup (distilling narrative into live
-    constraints) delegated to a Sonnet subagent, so that distillation quality is
-    high and doesn't drop the constraint that mattered.
-18. As a developer, I want cleanup to run only on a clean/committed tree, or to
-    auto-commit a WIP checkpoint first, so that my uncommitted work is never
-    lost.
-19. As a developer, I want each cleanup run to land as a single reviewable
-    commit, so that I can inspect or revert the whole sweep trivially.
-20. As a developer, I want to scope a cleanup to specific categories or files
-    (e.g. "only the orphaned-reference fixes"), so that I stay in control of how
-    much changes at once.
-21. As a developer, I want a `sweep` command that runs check-then-clean, so that
-    when I already trust the project I can do both in one step.
-22. As a developer, I want `sweep` to still surface the report and gate
-    `confirm`-tier ops, so that the convenience path isn't a foot-gun.
-23. As a developer, I want a status command that reports last-check and
-    last-clean timestamps for the current project, so that I can see where it
-    stands without running anything.
-24. As a developer, I want to protect files from being flagged via
-    `hygiene: frozen` frontmatter or a `.dochygiene-ignore` file, so that
-    deliberately-frozen records and append-only logs aren't repeatedly flagged.
-25. As a developer, I want sensible scope defaults (markdown + known doc
-    locations; excluding build/vendor/archive/graphify-out dirs) with
-    per-project overrides, so that the scan targets docs and nothing irrelevant.
-26. As a developer, I want the check and clean steps to update their own
-    timestamps (`last_check`, `last_clean`) and the reminder to track
-    `last_reminded`, so that the lifecycle is observable and the snooze works.
-27. As a developer, I want the plugin to work in any project where it's enabled
-    without per-project setup beyond enablement, so that adoption is frictionless.
-28. As a developer, I want classifier behavior protected by golden examples and
-    invariants, so that future edits to the plugin don't silently regress what
-    counts as stale vs bloat.
-29. As a developer, I want decisions (especially `confirm`-tier approvals)
-    recorded, so that there's an audit trail of what was changed and why.
-30. As a developer, I want the deterministic scripts to emit structured JSON and
-    correct exit codes, so that they're independently testable and composable.

-## Implementation Decisions
-
-**Distribution & activation**
-- New plugin `doc-hygiene` in the `cc-plugins` marketplace. Installed globally,
-  operates per-project. No global state index — the question of "how to key
-  projects globally" is dissolved by per-project storage.
-- Marketplace registration deferred until the plugin is functional (documented
-  as a build-completion step, not done now).
-
-**State & artifacts (in-project)**
-- A gitignored `.dochygiene/` directory at the project root (resolved via git
-  root, fallback cwd) holds:
-  - `state.json` — `last_check`, `last_clean`, `last_reminded` timestamps.
-  - the single most-recent report (human `.md` + machine `.json`).
-- Rollover: each new check deletes the prior report before writing the new one.
-- `.dochygiene/` must not be tracked. The tool does **not** silently edit the
-  user's `.gitignore` (that would itself be an outward mutation, against the
-  non-intrusive premise). Instead: on first check it detects whether the dir is
-  ignored and, if not, surfaces a one-line offer to add the entry — applied only
-  on confirmation (or noted in the report). The scanner always self-excludes
-  `.dochygiene/` regardless.
-
-**Components / modules** (described abstractly; see CLAUDE.md for the build map)
-- **State store** (deterministic): reads/writes `state.json`; atomic writes;
-  resolves project root.
-- **Scanner** (deterministic): walks scoped files, computes signals, emits a
-  candidate shortlist with attached signals. Respects scope config + ignore
-  markers + frozen frontmatter + append-only detection.
-- **Reminder hook** (deterministic, `SessionStart`): reads state, compares to
-  staleness threshold, applies once/day snooze via `last_reminded`, emits a
-  noticeable notice. No model.
-  - *Mechanism (confirmed):* plugins declare hooks in `hooks/hooks.json` at the
-    plugin root (not under `.claude-plugin/`). The visible, zero-token notice is
-    emitted via the hook's JSON `systemMessage` field (a user-facing banner) —
-    NOT `additionalContext` (which is silent to the user). The command names the
-    slash command to run. `matcher` is `startup|resume`.
-  - *Snooze is load-bearing, not polish:* `SessionStart` also fires on `resume`,
-    `clear`, and `compact`. The once/day `last_reminded` snooze is what prevents
-    the banner re-firing after every compaction within a single working session.
-  - *Constraints to respect:* keep `timeout` low (≤5s); exit 0 (never block the
-    session); the script must be fast and side-effect-free beyond reading state.
-- **Classifier / report builder** (AI — the `check` skill): consumes the
-  shortlist, reads candidates, assigns category + op-type + safety tier, writes
-  exact edits for deterministic ops, and calls the token estimator. Emits human
-  + machine reports. Updates `last_check`.
-- **Token estimator** (deterministic helper): counts tokens of removed/reduced
-  spans with a local tokenizer approximation (no API call); weights by injection
-  frequency; rolls up file → category → total. Framed as "context weight
-  reduced," splitting injected vs on-demand.
-- **Cleanup executor** (the `clean` skill + deterministic patch-applier):
-  consumes the machine report; mtime-guards each op; applies `deterministic` ops
-  mechanically; delegates `generative` ops to Sonnet subagents; runs `auto`
-  freely and escalates `confirm`; enforces git checkpoint + single-commit;
-  scopable by category/file. Updates `last_clean`.
-- **Sweep** (composition): invokes check then clean, preserving the report
-  surface and `confirm` gate.
-
-**Operation taxonomy**
-- Op-type `deterministic`: exact, reversible edits the check pre-computes
-  (delete/move/stamp/known-link-fix/exact-dedupe). Applied with no model.
-- Op-type `generative`: prose transformations (distill, split) requiring a model
-  at clean time (Sonnet). Deferred — not pre-written at check time — so a check
-  is cheap even when no clean follows.
-- Safety tier `auto`: deterministic + reversible + objective → runs without
-  prompt.
-- Safety tier `confirm`: destructive (any delete), subjective, or generative →
-  escalated for approval.
-
-**Git safety (reversion-protection vocabulary)**
-- Cleanup requires a clean/committed working tree, or auto-commits a WIP
-  checkpoint first.
-- Each cleanup run lands as one reviewable commit (the post-state).
-- `confirm`-tier approvals are logged to a decisions record.
-
-**Model routing** (per the marketplace convention)
-- Deterministic scan/state/patch-apply/token-estimate: **no model** (scripts).
-- Writing those scripts: **Haiku**.
-- Classification / report building: **Sonnet** (reading comprehension +
-  judgment). The hardest stale-vs-bloat distinctions may escalate to **Opus**.
-- Generative distillation at clean time: **Sonnet** (explicitly *not* Haiku —
-  this is the highest-judgment task and Haiku produces lossy summaries).
-- Orchestration: **Opus** (the calling Claude).
-
-**Language**
-- **Python**, OOP, small composable single-responsibility classes with
-  dependency injection (per the deterministic-scripting reference), chosen for
-  broad reach in a general-purpose plugin and for testability.
-
-**Report schema is the linchpin**
-- The machine report schema (per-file: category, signals, recommended op,
-  op-type, safety tier, optional exact-edit, token estimate) is the contract
-  every other component consumes. It is designed and frozen first.
-
-## Testing Decisions
-
-**What makes a good test here:** assert external behavior at the highest
-deterministic seam — given an input doc tree / state file / report, the script
-produces the correct structured output and exit code. Do not assert internal
-class structure. The AI classification layer is pinned by golden examples, not
-unit assertions.
-
-**Seams (highest first):**
-- **Scanner** — input: a fixture doc tree; output: candidate shortlist JSON.
-  Unit-tested against fixtures exercising each signal (broken ref, version skew,
-  churn-vs-edit, location, append-only, frozen frontmatter, ignore file).
-- **State store** — timestamp read/write, rollover (only latest report kept),
-  snooze logic. Unit-tested with an injected clock and temp dirs.
-- **Reminder hook** — given a `state.json` + injected clock + threshold, asserts
-  notice / no-notice / snoozed. Unit-tested via the injected clock (no real
-  time, no real session).
-- **Token estimator** — counts on known spans; injection-frequency weighting;
-  bottom-up rollup. Unit-tested on fixed inputs.
-- **Patch-applier + mtime guard** — applies deterministic ops on fixtures;
-  skips when fixture mtime is newer than the check timestamp. Unit-tested.
-- **Classifier (AI)** — golden examples (`examples/golden/`): input doc tree →
-  expected report categorization, per the reversion-protection pattern. Run the
-  check against each; flag mismatches for human review.
-
-**Prior art:** the `commit` and `cc-architect` plugins pair deterministic
-`scripts/` with skills and structured output; this plugin follows that split.
-The reversion-protection reference (`cc-architect/.../reversion-protection.md`)
-defines the golden-example + invariants approach used for the classifier.
-
-## Out of Scope
-
-- A global cross-project dashboard / index (dissolved by per-project storage).
-- Exact Claude token counting via API at check time (local approximation only;
-  exactness isn't worth the latency/cost for a motivational estimate).
-- Non-markdown content analysis beyond known doc locations (e.g. linting source
-  code comments). Scope defaults to docs.
-- Auto-running cleanup from the `SessionEnd`/`SessionStart` hook — the hook only
-  ever reminds; all mutation is user-invoked.
-- Pushing commits or any outbound/network action — cleanup is local commits
-  only; the user pushes.
-- Editing files outside the resolved project root.
-- v2 polish: richer per-category savings visualizations, configurable op
-  taxonomies beyond the built-in set.
-
-## Further Notes
-
-- **Build order** (the report schema gates everything): (1) machine report
-  schema; (2) deterministic scanner + state store + reminder hook; (3) `check`
-  skill (scanner → AI classify → report); (4) `clean` skill (consume report,
-  git-safe, scoped) + `sweep`; (5) bonus: deterministic patch-apply + token
-  estimator. Patch-apply and token-estimate are explicitly v2 — they optimize a
-  report format that must exist and be proven first.
-- **Why deterministic-first matters here specifically:** the check does the
-  expensive cognition once (reading + deciding); cleanup executes. Pushing
-  attribute-detection into the scanner and exact edits into the report means
-  most cleanup needs no model at all, and a check is cheap even when no cleanup
-  follows.
-- **False-positive trust risk:** without the frozen/ignore mechanism and
-  append-only detection, the tool would re-flag deliberately-frozen records
-  every week and lose the user's trust. This is treated as a correctness
-  requirement, not a nicety.
-- **The tool must not become bloat:** report rollover (keep latest only) and the
-  gitignored dot dir are deliberate guards against the plugin polluting the very
-  repos it cleans.
-- **Linchpin mechanism verified:** the SessionStart `systemMessage` banner path
-  was confirmed against the Claude Code hook docs before this PRD was finalized
-  (no other plugin in the collection wires a CC hook, so it had no precedent).
-  Build-spike #1 is still to stand up a trivial `hooks/hooks.json` emitting a
-  `systemMessage` and confirm it renders visibly in a real session before
-  building the deterministic core on top of it.

-# examples/golden/
-
-Two **distinct** families of golden fixtures live here. Do not conflate them.
-
-| Family | Location | Maps | Consumed by | Purpose |
-|--------|----------|------|-------------|---------|
-| **Schema-shape fixtures** | `valid_report.json`, `invalid_report.json` | (a hand-authored report) → accept / reject | `scripts/validate_report.py` | Pin the frozen machine-report schema contract. |
-| **Classifier goldens** | `classifier/<n>-<name>/` | input doc-tree (`input/`) → expected classification (`expected.json`) | hermetic `tests/test_classifier_golden.py` + a live model-regression harness | Layer-2 reversion protection for the *classifier* — pin which subtype + op-kind + tier a given doc-tree should yield. |
-
-Both families are reversion-protection artifacts; changing either is **human-gated**
-per the META-RULE in `invariants.md`.
-
-## Schema-shape fixtures
-
-Hand-authored machine-report JSON files used to verify the schema-validator
-script (`scripts/validate_report.py`).
-
-## Contents
-
-| File | Purpose | Expected validator result |
-|------|---------|--------------------------|
-| `valid_report.json` | Well-formed machine report exercising a realistic spread of entry types: deterministic `delete-range` (confirm), deterministic `move-to-archive` (auto), deterministic `insert-frontmatter` (auto, no anchor — exercises the no-anchor path), and a generative distillation entry (confirm). | Exit 0 (accepted) |
-| `invalid_report.json` | Malformed report with a safety-critical invariant #10 violation: a `delete-range` entry (destructive, irreversible) that records `safety_tier: "auto"` when the derivation yields `"confirm"`. All other fields are otherwise valid so the validator reports only this specific violation. | Exit 1 (rejected), one violation on `entries[0].safety_tier` |
-
-## Invariants exercised
-
-- **Invariant #10** (`safety_tier` derivation): `invalid_report.json` is the
-  canonical fixture for this invariant — it is structurally sound except for the
-  safety-tier mismatch.
-- **Invariant #11** (`op_type`↔`exact_edit` biconditional): both fixtures
-  include deterministic entries with `exact_edit` and a generative entry without
-  one, exercising both directions of the biconditional.
-
-## Classifier goldens (`classifier/`)
-
-Input doc-tree → expected classification. See `classifier/README.md` for the full
-case table, the two harnesses (hermetic unit + live model-regression), and the
-regeneration recipe. Five cases, each pinning one taxonomy edge to a **distinct**
-`exact_edit.kind` (plus one generative case) so the suite covers the kind table +
-tier derivation:
-
-| Dir | class / subtype | kind | tier | scanner signal |
-|-----|-----------------|------|------|----------------|
-| `1-orphaned` | stale / orphaned | `delete-range` | confirm | `broken_reference` |
-| `2-superseded` | stale / superseded | `move-to-archive` | auto | `stale_name_location` |
-| `3-completed-in-place` | stale / completed-in-place | `insert-frontmatter` | auto | `archive_to_live_ratio` |
-| `4-duplicated` | stale / duplicated | `dedupe` | auto | `stale_name_location` (no dedicated dup signal — see case notes) |
-| `5-distill` | bloat / distill | (none, generative) | confirm | `archive_to_live_ratio` |
-
-Enforced hermetically by `tests/test_classifier_golden.py` (no model, no network).
