# v5.3.0 Release — Multi-Session Plan

_Status: PLANNED. No version bump yet. `plugin.json` = 5.2.0. All work below is gated on
explicit operator GO per session. Plans live next to STATE per the continuity system._

## Goal

Release **v5.3.0** (minor, backward-compatible) covering the work that has accumulated on
`main` since the v5.2.0 release (`1576909`, 2026-06-18), with a **fully updated README +
CHANGELOG**. The features are already implemented and on `main`; the bulk of this release is
documentation, changelog narrative, version sync, and a tag — plus a decision on whether any
remaining CC-gap items should ship in 5.3.0 first.

## Pre-verified facts (do NOT re-derive)

- Last release: **v5.2.0** = commit `1576909`, 2026-06-18. Prior: v5.1.0 (2026-05-01).
- Unreleased commits on `main` since v5.2.0 (8):
  | Commit | Type | 5.3.0 changelog section |
  |--------|------|-------------------------|
  | `0a631e3` | refactor(skl): extract skill-listing budget to shared lib | Internal |
  | `dfe9049` | feat(feature-gap): `disableBundledSkills` under listing pressure | Added |
  | `03949c6` | feat(dis): ineffective allow wildcards; `Tool(*)` = deny-all | Added |
  | `b0bf8c5` | feat(cml): context-window-scaled CLAUDE.md char budget | Added |
  | `d678765` | feat(dis): forbidden-param permission rules | Added |
  | `c6c5f17` | feat(plh): plugin namespace collision (same declared name) | Added |
  | `0874188` | fix(plh): cross-plugin command overlap HIGH→LOW | **Changed** |
  | `96743ec` | fix(readme): add SKL row to scanner table `[skip-docs]` | Fixed (docs) |
- **Scanner count unchanged: 13.** The 7 features extended EXISTING scanners (CML/DIS/PLH/GAP) —
  no new scanner file. So the `scanners-13` badge, the table (now 13 rows after `96743ec`), and
  `countScannerShape` need **no change** for 5.3.0. Do not bump the scanner badge.
- **One behavior change to call out** (`0874188`): the cross-plugin command-name finding went
  **HIGH → LOW** and was reframed from "conflict" to "ambiguity" (namespacing keeps both
  commands reachable). Scoring impact: any config with cross-plugin command-name overlap scores
  slightly higher now. Not a `--json`-shape break; no test asserted the old HIGH (verified
  2026-06-19). Document under **Changed**, not Breaking.
- Suite at HEAD: **936/936**. self-audit: configGrade A 97, pluginGrade A 100, readmeCheck.passed.
- Edit-target files (from the v5.2.0 release pattern, `docs/v5.2.0-release-plan.md`):
  `.claude-plugin/plugin.json`, `README.md` (badges + What's New + version-history row + TOC),
  `CHANGELOG.md` (`## [5.3.0]` block above `## [5.2.0]`), and `docs/cc-2.1.x-gap-matrix.md`.

---

## Session A — Release-readiness audit & scope decision (read/plan; 1 doc output)

**No code changes.** Decide exact 5.3.0 scope and surface the "build more first?" question.

1. **Reconcile `docs/cc-2.1.x-gap-matrix.md` against current code.** STATE flags it as stale.
   For each matrix row, mark which of the 7 feature commits closed it; list every still-open gap.
2. **Classify each still-open gap** → `ship-in-5.3.0` / `defer-to-5.4` / `wontfix`, with a
   one-line rationale and effort tag. **Operator GO required** on the ship-list before any build.
3. **Draft the CHANGELOG narrative** — map all 8 unreleased commits to Added/Changed/Fixed/Internal
   bullets (table above is the starting point). Draft the "What's New in v5.3.0" prose.
4. **Confirm version = 5.3.0** (minor) and write the Changed-note for the PLH severity downgrade.
5. **Knowledge review** — check whether any `knowledge/*.md` corpus file needs an update for the
   7 features (e.g. permission-rule or plugin-namespacing corpus). List files to touch, if any.

**Output:** updated `cc-2.1.x-gap-matrix.md`; a `## v5.3.0 scope decision` block appended to THIS
file (ship-list + operator GO + draft changelog bullets + knowledge-touch list).

**Verifisering (testbar):**
- Every one of the 8 unreleased commits appears in exactly one draft changelog bullet.
- Every still-open matrix gap has a `ship/defer/wontfix` verdict recorded.
- Operator GO on the ship-list is recorded verbatim in the scope-decision block.
- `git log 1576909..HEAD` count matches the number of mapped commits (no commit dropped).

---

## Session B — (conditional) implement approved remaining features

**Runs only if Session A's ship-list is non-empty.** If empty → skip entirely; 5.3.0 is a
docs-and-release-only version.

- One feature per chunk, **/tdd: failing test FIRST** (Iron Law), then minimal implementation.
- Per feature commit: self-audit gates + docs-gate (README **and** CLAUDE ≥3 substantive lines, or
  `[skip-docs]` for non-feature commits). Stage docs in a separate Bash call before commit.
- If a feature adds a **new scanner**, THEN (and only then) bump the `scanners-` badge, the table,
  and `countScannerShape` — and note it for Session C's "What's New".
- Checkpoint STATE + this plan after each feature (chunk-before-compaction).

**Verifisering (per feature):** new tests RED→GREEN; full suite N/N; self-audit configGrade ≥ A,
pluginGrade ≥ A, readmeCheck.passed; contamination-grep + gitleaks clean on any snapshot/fixture touch.

---

## Session C — Release v5.3.0 (version sync + docs + tag + push)

1. **Bump** `.claude-plugin/plugin.json` 5.2.0 → 5.3.0. (Version lives ONLY here per STATE.)
2. **README:**
   - `version-` badge → 5.3.0; `tests-` badge → current exact case count.
   - Replace "What's New in v5.2.0" with **What's New in v5.3.0** (+ update the TOC anchor at the top).
   - Insert a new **version-history table row** above the `**5.2.0**` row.
   - Sweep for stale prose. **Scanner count stays 13** unless Session B added a scanner.
3. **CHANGELOG.md:** insert `## [5.3.0] - <release-date>` block above `## [5.2.0]`
   (Added / Changed / Fixed / Internal / Test count / Verification — mirror the 5.2.0 block).
4. **Knowledge/docs:** apply any updates Session A flagged.
5. **Marketplace cross-repo (CONDITIONAL — verify first):** check whether the marketplace catalog
   (`../.claude-plugin/marketplace.json` or the marketplace README) references config-audit's
   version or feature list. If yes → update there too. Separate repo → **same push-window rules,
   separate push**. (Not yet confirmed to exist; Session C verifies before assuming.)
6. **Gates (all must pass before commit):**
   - `node --test 'tests/**/*.test.mjs'` → N/N green.
   - `node scanners/self-audit.mjs --json --check-readme` → readmeCheck.passed, configGrade A,
     pluginGrade A, scanner count consistent with badge+table.
   - SC-5 snapshot byte-equal (or re-seeded + contamination-grep clean); gitleaks clean.
7. **Commit** `release: v5.3.0 — <one-line summary>`, **tag** `v5.3.0`, **push** (plugin repo;
   marketplace repo if step 5 applies) inside the push window.

**Verifisering (testbar):**
- `git tag --list v5.3.0` returns `v5.3.0`.
- README `version-` badge value == `.claude-plugin/plugin.json` `version`.
- `self-audit --check-readme` → `readmeCheck.passed: true`, badge tests == suite case count.
- `git log -1` subject starts with `release: v5.3.0`.
- If marketplace updated: its config-audit entry shows 5.3.0.

---

## Key assumptions (test, don't trust)

- **5.3.0 is non-breaking.** Verify: `json-backcompat` + `raw-backcompat` + snapshot tests green
  (they are at HEAD); the PLH severity change alters a severity VALUE, not the `--json` shape, and
  no test/consumer asserts the old HIGH. If Session B adds anything that changes the JSON shape or
  scoring math materially → re-classify as a Breaking note (like the 5.0.0 row).
- **docs-gate** blocks any commit lacking ≥3 substantive lines in BOTH README and CLAUDE — use
  `[skip-docs]` for pure release/doc commits, or make both edits substantive. (Proven 2026-06-19.)
- **self-audit `--check-readme`** only checks badge NUMBERS vs filesystem, NOT prose-table
  completeness — so manually re-verify the scanner table and "What's New" by eye (the SKL-row gap
  `96743ec` slipped exactly because the gate is number-only).

## Out of scope (do not start without separate GO)

- New CC-gap features beyond Session A's approved ship-list.
- Any scanner refactor not required by an approved feature.
- Marketplace-wide changes beyond the config-audit catalog entry.

## v5.3.0 scope decision (Session A output, 2026-06-19)

### Operator GO (recorded verbatim)
> **"Release-only, ship-list tom"** — Session B SKIP; knowledge-backing (disableBundledSkills,
> 40k char-budget, forbidden-param) folded into Session C; open M-gaps → v5.4 backlog.

**Ship-list = EMPTY.** Session B is skipped entirely. v5.3.0 is a docs + knowledge + release
of the work already on `main`. No new feature build.

### Reconciliation result (matrix vs. current code)
The gap-matrix was the **v5.2.0** plan. Verified against HEAD: the entire HIGH-priority
false-positive cluster is **already CLOSED** — `settings-validator` (all 11 keys + `xhigh`),
`hook-validator` (28 events incl. `MessageDisplay`/`post-session`), `mcp-config-validator`
(POSIX/auto-injected env + `trust` removed), `claude-md-linter` (HIGH→MEDIUM reframe), DIS/CNF
(param-aware). The 8 unreleased commits add incrementally on top. **No active false positive or
behavior bug remains unshipped.** Full row-by-row verdicts appended to `cc-2.1.x-gap-matrix.md`.

### Still-open gaps → verdicts (all defer; none are bugs)
| Gap (matrix row) | Effort | Verdict |
|---|---|---|
| PLH shadow-folder: plugin.json key shadows default component folder (129) | M | defer-5.4 |
| permissions: acceptEdits prompts on shell-startup/build-config writes (141) | M | defer-5.4 |
| permissions: Read-deny hides Glob/Grep; Windows backslash/case path (140) | M | defer-5.4 |
| settings: autoMode.hard_deny nested-structure validation (144) | M | defer-5.4 |
| PLH: validate `skills:` array entries are dirs within plugin (130) | M | defer-5.4 |
| CLAUDE.md: nested `.claude` closest-wins conflict detection (104, 131) | M | defer-5.4 |
| Knowledge L-rows: env vars, model-lineup nuance, hook-output fields, plugin/skill doc rows | S | defer (rolling knowledge maintenance) |

### Draft CHANGELOG narrative (all 9 commits `1576909..HEAD` accounted for)

**Added**
- **DIS forbidden-param rules** (`d678765`) — flags `Tool(param:value)` whose key is the tool's
  own canonicalizing field (`command`/`file_path`/`path`/`notebook_path`/`url`); CC ignores these
  and emits a startup warning. Severity by intent: **deny/ask = false security (medium)**,
  **allow = dead config (low)**. Valid forms (`Bash(npm:*)`, `WebFetch(domain:host)`,
  `Agent(model:opus)`) never flagged. Predicate `forbiddenParamRule` in `permission-rules.mjs`.
- **DIS ineffective allow wildcards + `Tool(*)` deny-all** (`03949c6`) — flags unanchored
  tool-name globs in `permissions.allow` (`*`, `B*`, `mcp__*`) that CC silently skips (low);
  treats `Tool(*)` as deny-all (`Bash(*)` ≡ `Bash`) so a bare allow killed by it is reported
  as dead config. Valid `mcp__<server>__*` never flagged.
- **CML context-window-scaled char budget** (`b0bf8c5`) — new `CA-CML` finding mirroring CC's
  startup warning *"Large CLAUDE.md will impact performance (X chars > 40.0k)"*. Anchors on the
  conservative 200k window; discloses the relaxed ~200,000-char figure at 1M context. Severity
  **medium** (token cost). Char-keyed, complementary to the 200/500-line checks. Window constants
  in shared `scanners/lib/context-window.mjs`.
- **PLH plugin namespace collision** (`c6c5f17`) — flags 2+ discovered plugins declaring the same
  `name` in `plugin.json`. Namespaces collapse; CC picks an undocumented winner; the loser's
  commands/skills/agents go silently unreachable. Severity **medium** (dead config),
  `category: 'plugin-hygiene'`, COL-shaped `details.namespaces`. Keys on declared `name`, not
  `basename(dir)`; name-less plugins excluded.
- **feature-gap `disableBundledSkills` lever** (`dfe9049`) — conditional recommendation to set
  `disableBundledSkills` when the active skill listing is over budget; remediation companion to
  SKL `CA-SKL-002`.

**Changed**
- **PLH cross-plugin command-name overlap: HIGH → LOW** (`0874188`) — reframed from "conflict" to
  "ambiguity". Commands are namespaced (`/name:command`) so both stay reachable; only a same-`name`
  plugin collision loses components (covered by the new namespace-collision finding). Now
  group-first (one finding per command name listing every namespace), COL-shaped
  `details.namespaces`. The old HIGH `Cross-plugin command name conflict` finding **and its
  humanizer entry are removed**. Scoring impact: configs with cross-plugin command overlap score
  slightly higher. **Not a `--json`-shape break** — no test/consumer asserted the old HIGH.

**Fixed**
- **README scanner table** (`96743ec`) — added the missing SKL row (12 → 13 rows); the prose table
  lagged the badge/self-audit count (the `--check-readme` gate is number-only and didn't catch it).

**Internal**
- **Extract skill-listing budget to shared lib** (`0a631e3`) — `scanners/lib/context-window.mjs`
  as single source of truth for the 200k/1M window constants, re-exported by
  `skill-listing-budget.mjs` and consumed by the new CML char-budget finding.

**Excluded from changelog:** `9b828fa` `docs(plan): v5.3.0 multi-session release plan [skip-docs]`
— the plan meta-commit itself, not a product change. (9 commits total = 8 mapped + 1 excluded.)

### What's New in v5.3.0 (draft prose)
> **v5.3.0 — permission-rule & plugin-hygiene hardening.** Five additive scanner findings extend
> the permission, CLAUDE.md, and plugin surfaces: DIS now catches forbidden-parameter rules and
> ineffective allow-wildcards that Claude Code silently ignores; CML mirrors CC's own 40.0k-char
> "large CLAUDE.md" startup warning, context-window scaled; PLH flags two plugins that declare the
> same name (one silently shadows the other); and feature-gap recommends `disableBundledSkills`
> when the skill listing is over budget. The cross-plugin command-name finding is reframed from a
> HIGH conflict to a LOW ambiguity to match Claude Code's namespacing. Scanner count stays **13**
> (all extend existing scanners). `--json`/`--raw` remain byte-stable.

### Version & non-breaking confirmation
- **5.3.0** (minor). Additive findings + one severity downgrade (PLH HIGH→LOW). No envelope/JSON
  shape change; `json-backcompat` + `raw-backcompat` + SC-5 snapshot green at HEAD. The PLH change
  alters a severity VALUE, not the shape. **Document the downgrade under Changed, not Breaking.**

### Knowledge-touch list (apply in Session C step 4)
Three short backing entries for the v5.3.0 features (rows currently absent from the corpus —
verified by grep, 0 files each). Pure docs, no scanner/test impact:
1. `knowledge/prompt-cache-patterns.md` — `disableBundledSkills` as a token-efficiency lever
   (hides bundled-skill descriptions from the system prompt). (matrix row 167)
2. `knowledge/claude-code-capabilities.md` *or* `prompt-cache-patterns.md` — the CC 40.0k-char
   "Large CLAUDE.md will impact performance" startup warning + 2.1.169 context-window scaling
   (backs the new CML finding).
3. `knowledge/claude-code-capabilities.md` — `Tool(param:value)` permission semantics: param
   matching is deny/ask-only, and the canonicalizing-field rules CC ignores (backs DIS
   forbidden-param). (matrix rows 137, 139)

Everything else in the matrix (env-var rows, model-lineup nuance, hook-output fields, plugin/skill
doc rows) → **defer** to rolling knowledge maintenance; not required for 5.3.0 correctness.
