+name: Tag and release from CHANGELOG
+
+# Runs after each push to main. If CHANGELOG.md gained a new ## vX.Y.Z heading
+# anywhere in this push's commit range (compared to the push's `before` SHA):
+#   1. gate the release — the version in .claude-plugin/marketplace.json must
+#      match the new heading, and the validator + test suite must pass
+#      (the suite also asserts every plugin.json carries the same version), then
+#   2. create a lightweight tag with that version name at the pushed commit, and
+#   3. publish a GitHub Release for that tag with the matching CHANGELOG
+#      section as the notes.
+#
+# CHANGELOG is the source of truth; the tag and the Release are deterministic
+# projections of it. Adapted from phuryn/claude-usage's tag-on-merge workflow,
+# minus the .vsix build. Added headings whose tag already exists are treated as
+# backfilled history and skipped, so importing old releases is safe.
+#
+# No action when CHANGELOG wasn't touched, when an existing version heading was
+# edited (not added), or when the tag/release already exists. Safe to re-run on
+# force-pushes and amends.

+## Unreleased

+### pm-ai-shipping
+
+- Added the **code-review** skill: correctness is the core engine, with performance and security as optional sub-cases of it rather than separate methods. It anchors on agreements between participants across a boundary — the defects that stay invisible file-by-file because each side reads as reasonable alone — forces a violating execution, and refutes every candidate before reporting.
+- Added a correctness taxonomy reference built from real fix history, plus performance and security reference sheets the same engine reads.
+- `/ship-check` gained a correctness review as Step 3, before the security and performance audits, and an independent unsteered pass by a second model as Step 6.
+- `/security-audit-static` gained an OWASP Top 10 coverage backstop: every surviving finding is mapped to a category, and any category with zero findings is flagged "not covered — double-check" rather than silently passing. It is a coverage check, not a mandate to invent findings.
+
+## v2.1.0 — 2026-07-03
+
+### pm-ai-shipping
+
+- `/security-audit-static` findings now carry a mandatory **Evidence** line (`file:line` + verbatim snippet), and every citation is re-verified against the file before the final report ships.
+- Subagent fan-out has a concrete trigger (scope over ~30 files / ~5,000 lines) and a structured candidate-record contract, so parallel audit slices merge cleanly into one self-refute pass.
+- `/performance-audit-static` now hunts **N+1 queries and request waterfalls** — the most common perf failure in AI-generated code — alongside over-fetching, indexes, and caching, and gained a refute-before-reporting pass (dynamic field access, existing indexes, hot-path evidence).
+- Both audit commands pre-approve a read-only toolset (`allowed-tools`): read, search, fan out, and write under `reports/` — never edit the code under audit.
+- The audited repo is treated as untrusted input across the kit: instructions embedded in code, comments, or docs are data to analyze — a steering attempt is itself a finding — never directives to follow.
+- `/ship-check` runs the security and performance audits as parallel subagents once the docs exist.
+- Security reports gained severity anchors (what Critical/High/Medium/Low mean) and a consolidation rule (more than ~12 findings → lead with the worst, group the tail by root cause).
+- Docs and reports now use repo-relative paths (`documentation/`, `reports/`) — the old absolute forms (`/documentation`) could resolve to the filesystem root — and reports are always written, with the path announced, instead of "optionally".
+
+### Repo
+
+- Added this `CHANGELOG.md` as the release source of truth with auto-tag-and-release on merge (adapted from [claude-usage](https://github.com/phuryn/claude-usage)): pushing a new `## vX.Y.Z` heading to `main` tags that version and publishes a GitHub Release with the section as notes — gated on the test suite and a version-sync check.
+- Added a test suite (`tests/`) and a Tests workflow (every PR and push to `main`): plugin-spec validation plus docs consistency — README skill/command counts vs. disk, marketplace plugin list vs. directories, version sync across all manifests, CHANGELOG format.
+- CONTRIBUTING now documents the changelog convention (every user-facing change gets a bullet; contributors credited inline) and the release procedure.
+- Docs since v2.0.0: native Codex CLI install path; companion badges (burnstop, claude-usage).
+
+## v2.0.0 — 2026-06-05
+
+- Added the **pm-ai-shipping** plugin (AI Shipping Kit): `/ship-check`, `/document-app`, `/derive-tests`, `/security-audit-static`, `/performance-audit-static`, plus the `shipping-artifacts` and `intended-vs-implemented` skills.
+- Added the `strategy-red-team` skill and `/red-team-prd` command to pm-execution.
+- Refreshed the root README; added `CLAUDE.md` / `AGENTS.md` agent guidance.

+## Changelog & Contributor Credit
+
+Every user-facing change gets a bullet in [CHANGELOG.md](CHANGELOG.md). In a PR, add yours under a `## Unreleased` heading at the top (create it if it doesn't exist) and credit yourself at the end of the bullet — `(#123, thanks @your-handle)`. Credits ship verbatim in the GitHub Release notes and stay in the changelog permanently.
+
+## Releases (maintainer)
+
+`CHANGELOG.md` is the source of truth; tags and GitHub Releases are deterministic projections of it (`.github/workflows/tag-on-merge.yml`):
+
+1. Rename `## Unreleased` to `## vX.Y.Z — YYYY-MM-DD`. Semver: breaking changes = major, new skills/commands or changed behavior = minor, fixes and docs = patch.
+2. Set the same version in `.claude-plugin/marketplace.json` and every plugin's `plugin.json` — versions stay in sync across the repo (the test suite enforces this).
+3. Push to `main`. CI verifies the version sync, runs the validator and test suite, then tags `vX.Y.Z` and publishes a GitHub Release with the changelog section as notes. No new heading → no release; ordinary pushes are unaffected.

 - **shipping-artifacts** — The durable documentation set that makes an AI-built app reviewable: a core every app needs (architecture, user/permission flows, permissions, variables/secrets, test-coverage map) plus conditional docs added only when they apply (emails, cron, SEO, embedded agents/automation). Defines what each doc must capture and how a reviewer uses it.

+Audit **$ARGUMENTS**. If empty, review the whole repository, prioritizing list and dashboard views, frequently hit endpoints, and large tables.

+
+## Model and orchestration
+
+- **Run every subagent on the strongest model available** — Fable or Mythos when you have access, otherwise Opus 4.8. Match the **effort level of the current session** when the surface exposes it.

One level is the target; nest a second only when a cluster is too big for one agent's context. Don't reach for a self-generating workflow.
+- **Reroutes are unlikely here, but report them if they happen.** Unlike the security audit, performance work rarely trips Fable's safety classifiers. If a cluster does get rerouted to Opus 4.8, note it in the report so the reader knows the model mix.

 ## The audit

-### 1. Over-fetch in view payloads
+### 1. N+1 queries and request waterfalls
+
+The most common perf failure in AI-generated code. Review loops and per-item rendering paths for a query or fetch executed per row — a list view that runs one query for the list, then one more per item. Also flag sequential `await` chains where the calls are independent (could be batched, joined, or run in parallel) and unbounded reads (no `LIMIT`/pagination) feeding paginated UIs. Recommend the specific join, batch query, or parallelization that removes the loop.
+
+### 2. Over-fetch in view payloads

 Review components that render list or dashboard views. Identify fields fetched from the database but never used in the frontend, `SELECT *` on wide tables, missing pagination, absent lazy loading, and redundant loads. Suggest a minimal field set per component or route.

-### 2. Missing or inefficient indexes
+### 3. Missing or inefficient indexes

 Review queries, filters, and RPCs used in production views. Identify missing or inefficient indexes based on sort, filter, and join conditions, focusing on large tables and hot endpoints. Give specific index definitions, not "add an index."

-### 3. Caching opportunities
+### 4. Caching opportunities

 Review endpoints and data-access patterns for frequently called paths that return static or rarely changing data. Identify where frontend or backend caching helps, and specify the invalidation rule for each — caching without an invalidation plan is a correctness bug in waiting.

+### 5. Refute before reporting
+
+Try to disprove each finding; keep it only with cited evidence (file:line):
+
+- Before flagging an unused field, grep for dynamic access — `row[field]`, object spreads into props, serializers, CSV/export paths — that consumes it invisibly.
+- Before flagging a missing index, check the schema and migrations for an existing one; primary keys and unique constraints already have indexes.
+- Before proposing a cache, cite why the path is hot (rendered per page load, called in a loop, hit by bots) — caching a cold path adds invalidation risk for nothing.

This is recall-first work: a missed cross-file flow is the costly failure, so don't let a cluster silently drop to a cheaper model or a lower effort.
+- **Expect reroutes, and report them.** A security audit is exactly the content Fable's safety classifiers screen for, so some subagents will be **automatically rerouted to Opus 4.8**. That is fine for this work — but say so. Note in the report which clusters ran on the fallback model, so the reader knows the audit's model mix instead of assuming one model saw everything.
+- **Flat fan-out, not a workflow.** One level of parallel subagents (parent → cluster auditors → merge) is the target. Nest a second level **only** when a single cluster is too big for one agent's context. A deep org chart or a self-generating workflow adds coordination cost without improving recall here.

+Everything above is *steered*: each pass looks for the classes its own checklist names, which is exactly why each pass is blind in the same places twice. This step is the backstop, and on a real release it is the highest-yield step in this sequence.
+
+Hand the subject to a **fresh session of a different model** — Codex (`codex exec`) is the usual choice, but any capable second model works — under three rules:
+
+1. **Fresh, never a resume.** Not the thread that wrote the code, and not one that has seen the earlier findings. A session that already argued the code is correct will argue it again.
+2. **No checklist and no pointer to prior findings.** The value here is what an unprimed reader notices. Giving it the audit output converts an independent sample into a confirmation pass.
+3. **Define the subject mechanically, not in prose.** Diff against the last release tag or the deployed branch, plus the working tree — e.g. `git log --oneline <last-tag>..HEAD` and `git status`. A described subject drifts; a computed one does not.
+
+**Verify every finding against the code by hand before it enters the packet.** An unsteered reviewer has no refutation discipline imposed on it, so it will produce confident findings that the code already prevents. Apply the **code-review** skill's keep/drop rule to each one: a finding survives only with a supported obligation, a feasible execution, a concrete contradiction, an observable consequence, and a counterargument you actually checked.
+
+Distinguish defects the change **introduced** from defects it merely **revealed** — both belong in the packet, but only the first blocks the change itself. On a release pass, repeat the loop until a round surfaces no introduced findings above Low.

+
+# Code Review
+
+## Purpose
+
+Most review output is noise: a list of things that *look* wrong, unranked, unrefuted, and impossible
+to act on. This skill produces the opposite — a small number of findings, each with a required
+behaviour, a feasible trigger, a concrete contradiction, an observable consequence, and the strongest
+counterargument already checked.
+
+Its central bet: **the defects reviewers miss are rarely visible inside one file.** They are
+disagreements between two participants that each look reasonable alone — a caller and a callee, a
+producer and a consumer, a writer and a later reader, two branches that should establish the same
+state. A checklist applied file-by-file cannot see those, because the two halves are never in view at
+the same time. So the unit of review here is the **agreement**, not the file.
+
+## Structure: one engine, three anchors
+
+Code review is the skill. **Correctness is its core** — the dimension generic tooling covers worst,
+and the one described in full below. **Performance and security are sub-cases**: the same engine, the
+same refutation discipline, the same report contract, with a different anchor and one or two extra
+rules each.
+
+| Sub-case | Anchor | Where its rules live |
+|---|---|---|
+| **Correctness** *(core, default)* | Agreements between participants across a boundary | This file + `references/correctness-taxonomy.md` |
+| **Performance** | Workload → resource demand → growth or contention → consequence | `references/performance-review.md` |
+| **Security** | Source → trust boundary → sink, with an attacker controlling the source | `references/security-review.md` |
+
+Read a sub-case's file only when that sub-case is selected. Each is short on purpose: it states what
+*differs*, and the rest of this file still applies.
+
+Sub-cases are independently *activated*, not mutually exclusive. One root cause can carry correctness
+and security impact — report it once, with both impacts.

+- **Scope:** use what was asked. Otherwise review working changes if present, else the repository.
+- **State the selected dimensions, the scope and the comparison baseline before investigating.**
+- Reviewing changes means following dependencies *beyond* the changed lines, and distinguishing
+  defects the change **introduced** from defects it merely **revealed**.
+- Review and report. Apply fixes only when asked.
+
+## Shared engine
+
+Every sub-case uses one skeleton. Only the anchor and the refutation rules differ.
+
+**Map a flow → identify an obligation → inspect every participant → construct a violating execution
+→ trace the consequence → attempt refutation → report.**
+
+Build one minimal map first: inputs, major execution flows, who owns which state, external
+dependencies, observable effects. Each selected sub-case enriches it — do not build three maps, and
+do not make a security-only run wait on correctness mapping.
+
+## Correctness: the agreement engine
+
+A *boundary* is semantic, not a file split. It separates a caller and a callee, two callbacks, two
+executions of the same function, a producer and a consumer, or a value written now and read later.
+
+For each consequential agreement, hold these in working notes — not in the report:
+
+```
+Participants:
+Value, entity or effect exchanged:
+Authority (who decides the real answer):
+Identity and lifetime/version:
+Required relationship:
+Evidence for that relationship:
+Relevant transitions or orderings:
+Observable consumer or consequence:
+```
+
+**Establish the obligation without inventing intent.** Evidence comes from specifications,
+documented contracts, language or protocol semantics, tests that encode an expectation, or a
+necessary producer/consumer relationship. A consumer's implementation alone does not prove the
+consumer is right. Where participants disagree, say why the disagreement produces a *wrong outcome* —
+sometimes the contradiction is certain while which side should change is genuinely open. Missing
+documentation is a limitation, not automatically a finding.
+
+**Start where agreements are most likely to break:** values transformed or negotiated, identities
+reassigned, work becoming asynchronous, state persisted and reloaded, several effects that must
+agree. Then do a local pass over ordinary decisions, arithmetic, boundaries and error branches — the
+anchor must not become a filter that discards plain bugs.
+
+### Force a violating execution
+
+A suspicion is not a finding until you construct the execution that breaks it. Where the
+implementation permits:
+
+- make a **requested** value differ from the **accepted or effective** one;
+- keep two operations live at once and vary their completion order;
+- change the relevant identity or generation between observation and use;
+- compare distinct transitions that should end in equivalent state;
+- inject failure between effects, and interruption before completion;
+- exercise empty, exact-boundary and adjacent-boundary inputs.
+
+Establish that each case is actually reachable. Do not assume it.
+
+### Two lenses that need a forced probe, not a mention
+
+Across a large evaluation of planted runtime defects in real codebases, two classes were almost never
+*even reported* by strong agents — not missed at the fix, missed at the look. Naming them in a
+checklist will not help; each needs an explicit probe:
+
+1. **Authority reconciliation.** Follow a proposed value through validation, normalisation,
+   negotiation or commit, and find downstream state still derived from the **proposal** where the
+   authority can return something different. *A requested value is not an applied value.* Probe:
+   force them apart and ask what still reads the request.
+2. **Identity and correlation.** Trace how an operation's result finds its originating entity, then
+   establish that the key is unique, stable and live for long enough — under overlap, reordering,
+   removal and reuse. A label, a position or arrival order is suspicious exactly when those
+   properties can fail. Probe: run two operations concurrently and complete them out of order.
+
+The full set of thirteen diagnostic lenses, each with a detection tell, is in
+`references/correctness-taxonomy.md`. They are overlapping lenses, not a quota to fill.
+
+## Refutation: the discipline that makes this worth running
+
+A candidate becomes a finding only with all five:
+
+1. **A supported obligation** — what must hold, and on what evidence.
+2. **A feasible execution** — inputs, state and ordering the real system permits.
+3. **A concrete contradiction** — where the obligation fails.
+4. **An observable consequence** — wrong output, state, effect, completion or progress.
+5. **An examined counterargument** — the strongest mechanism that would prevent or repair it.
+
+Actively hunt for the refutation: an enclosing guarantee that makes the execution impossible;
+synchronisation excluding the interleaving; reconciliation before any consequential read; an
+intentional contract; a precondition excluding the input; a different owner responsible for it.
+
+| Outcome | Rule |
+|---|---|
+| **Keep** | Evidence establishes the defect; the counterargument checked does not prevent it. |
+| **Drop** | Cited evidence defeats the execution, the obligation or the consequence. |
+| **Unresolved** | An essential contract or runtime fact is unknown. List it *separately from findings*. |
+
+Do not import the security sub-case's attacker/victim test into correctness. **A correctness defect
+can harm only the person who triggered it and still be serious.** Equally, "keep unless disproved" is
+too permissive here — an ungrounded suspicion with no constructed execution is not a finding. When
+both sub-cases are active, apply each test only to its own dimension.
+
+**Absorption is not prevention.** The most expensive refutation mistake is finding something
+downstream that happens to hide the defect - a cache that usually holds the value, a retry that
+usually succeeds, a default that is usually right - and dropping the finding. That is not a
+guarantee, it is a coincidence with good odds, and it fails the day the absorber is cold, evicted or
+reconfigured. Drop only on a mechanism that makes the execution *impossible*, and say which mechanism
+it was. For the same reason, **"it works nearly always" describes a race, not a refutation** - a
+timing window that usually resolves correctly is a finding, and the fact that you had to reason about
+which side usually wins is the evidence.
+
+Passing tests, unfamiliar code, a suspicious name, a missing test and a sibling difference are
+evidence to investigate — none of them is proof, and none is refutation. Deduplicate by violated
+agreement and root cause, never by file. There is no findings quota; zero supported findings is a
+valid result.
+
+## Parallelism
+
+Fan out over **complete flows or connected groups of agreements** — never over files, and never one
+agent per taxonomy class. Partitioning by file is precisely the split that hides cross-boundary
+defects, which are the ones worth finding.
+
+1. The coordinator builds the initial map and identifies shared state.
+2. Each worker gets a bounded flow, its participants, the selected sub-cases and open questions.
+3. Workers inspect **both sides** of their agreements and may follow dependencies outside their list.
+4. Workers return candidates, cited evidence, completed refutations and unresolved relationships.
+5. The coordinator reconciles assumptions and any relationship that crosses assignments.
+6. Strong candidates get a separate verification pass before they are reported.
+
+**Allow overlapping reads.** Two workers reading the same authority is far cheaper than either one
+holding half its contract. Keep integration capacity in reserve: an unresolved relationship spanning
+two assignments stays unexamined until someone closes it. One level of fan-out is the target; if
+delegation is unavailable or the scope is small, run the same procedure sequentially.
+
+**Run workers on the strongest model available, and match the current session's effort level.** This
+is recall-first work: a missed cross-boundary flow is the costly failure, and a worker that silently
+drops to a cheaper model or a lower effort is the cheapest way to lose one. If any worker is rerouted
+or downgraded, say which in the report — a reader who assumes one model saw everything will
+misjudge the coverage.
+
+**One model. Name it on every worker.** Fan-out here buys coverage, not a second opinion. Pass the
+coordinator's own model explicitly on each spawn — "inherit" is not a routing decision, and a worker
+that quietly lands on a cheaper model is the easiest way to lose a finding. **Do not bring in a
+different model**, to review or to cross-check, unless you are explicitly asked: mixing models makes
+the result unattributable, and when this skill is being measured or compared across models, one
+foreign worker invalidates the number. The independent second-model pass is a separate,
+explicitly-invoked step (`/ship-check` Step 6), never something this skill reaches for on its own.
+
+**Tell workers they are reading, not editing.** A review worker needs to read, search and navigate;
+it must not modify the tree. State that in the worker's instructions — a worker that starts editing
+drifts from reviewing into "helpfully" fixing and stops reporting what it silently repaired, and the
+findings can no longer be checked against the code they describe. Say it in the prompt rather than
+assuming the host will enforce it, and confirm the tree is unchanged when the run ends.
+
+## Report
+
+Lead with supported findings, ordered by impact. Keep severity separate from evidential strength.
+
+```
+Review scope:
+Comparison baseline:
+Selected dimensions:
+
+[Severity] [Dimension] Concrete consequence
+  Expectation:  required behaviour, and the evidence for it
+  Trigger:      feasible preconditions and execution
+  Defect:       the violated relationship
+  Evidence:     source locations for EVERY participant
+  Impact:       observable consequence and affected scope
+  Refutation:   strongest counterargument checked, and why it fails
+  Remedy:       minimal correction to the violated relationship
+  Verification: what was executed, versus established from source
+
+Coverage:
+Unexamined areas and essential unknowns:
+```
+
+Cite **both** participants for a cross-boundary defect, and do not group findings only by file — that
+hides the relationship the review exists to find.
+
+**Coverage means work performed, not boxes ticked.** For each selected sub-case report: examined with
+supported findings · examined, none supported · not applicable, with reason · not examined, with
+reason. Zero findings in a category does **not** mean "not covered", and a table of ticks is not
+evidence of completeness. Say "no supported findings in the examined scope" — never that the code is
+bug-free.

+# Correctness taxonomy — thirteen lenses, with detection tells
+
+*Reference for the correctness sub-case — the core of the `code-review` skill. The performance and
+security sub-cases have their own files alongside this one.*
+
+Overlapping diagnostic lenses, not a classification scheme and not a quota. Each entry says **how you
+detect it**, because a class name alone changes nothing about what a reviewer looks at.
+
+Lenses 1 and 2 are the ones strong reviewers — human and machine — miss most often, and the only two
+that warrant an explicit forced probe rather than a read-through. Both are failures of *looking*, not
+of judgement: the code reads sensibly at each participant, and the defect exists only in the
+relationship between them.
+
+---
+
+### 1. Authority reconciliation
+Follow a proposed value through validation, normalisation, negotiation or commit. Identify downstream
+state still derived from the **proposal** when the authority can legitimately return something
+different. Check that reconciliation happens *before* the first consequential use.
+
+> **A requested value is not an applied value.** Anywhere a system can say "I heard you, and here is
+> what I actually did", the reply is the authority — and the request is not.
+
+**Probe:** construct an execution where the effective answer differs from the requested one, then ask
+which stored state, which UI, which later call and which log line still carry the request.
+
+### 2. Identity and correlation
+Trace how an operation's result finds its originating entity. Establish the correlation key's
+**uniqueness, stability and lifetime** under overlapping operations, reordering, removal and reuse. A
+label, an index, a position or arrival order is suspicious exactly when one of those can fail.
+
+**Probe:** run two operations concurrently and complete them out of order. Then remove one mid-flight
+and reuse its slot.
+
+### 3. Freshness and generations
+Mark every value captured before a yield, await, callback, timer or lock release. Determine what can
+change before it is used, and whether the operation still targets the intended entity *and version*.
+Check what the code actually does with a stale result — ignore, apply, or apply silently.
+
+### 4. Lifecycle and derived state
+Compare every reachable construction, replacement, restoration, reset, failure and termination path.
+Look for derived fields or cached decisions correctly re-established on one path and wrongly retained
+on another. Two paths that should end in equivalent state are an agreement like any other.
+
+### 5. Atomicity and partial failure
+Split multi-effect operations at each failure and cancellation point. Is partial state permitted,
+recoverable and accurately reported? Look for success reported before the required effects are
+durable.
+
+### 6. Replay and effect cardinality
+Follow retries, duplicate delivery, repeated callbacks and re-entry into effects. Compare the actual
+delivery guarantee against the required effect count — especially where an effect costs money, sends
+a message or mutates a shared total. Inspect deduplication scope, lifetime, and behaviour after
+partial success.
+
+### 7. Composition and precedence
+Trace independently produced pieces through merge, reduction, ordering and dispatch. Compare the real
+overwrite and selection rules against the intended authority or priority — including transformations
+applied *after* the merge that quietly re-order or re-key it.
+
+### 8. Bounds, units and accounting
+Follow counts, lengths, offsets, capacities and totals through every transformation. Check empty and
+boundary cases, overflow, rounding, and whether measurement and consumption use the same unit and
+representation.
+
+### 9. Framing and incremental processing
+Compare logical item boundaries against actual read, write, iterator and callback boundaries. Test
+split items, combined items, partial writes and early termination. Inspect buffering, flush and
+finalisation — especially the last item.
+
+### 10. Representation and information loss
+Compare the values a producer can emit against the distinctions a consumer relies on. Trace
+round-trips and derived outputs for distinctions that disappear. **This is the highest-frequency
+class in every corpus examined** - planted and natural - so give it more than one pass.
+
+Three sub-shapes carry most of it:
+
+- **The nullish family.** *Pending*, *absent*, *empty*, *zero*, *false* and *failed* are six different
+  states that collapse into each other with alarming ease. A failed read returning an empty result, a
+  never-started resource reported as broken, a guard that excludes `null` but not `undefined`, an
+  explicit null skipped as though the field were missing, a string `"false"` landing in a boolean, a
+  sentinel like `-1` standing in for "no answer" and then being counted. **Probe:** for each value
+  that can be missing, enumerate which of the six it can actually be, and check the consumer
+  distinguishes the ones that matter.
+- **Projection and field-set drift.** A producer - a query, a DTO, a serialiser, a mapper - stops
+  emitting a field, and consumers degrade silently rather than failing. **Probe:** diff the field set
+  a producer actually selects against every field its consumers read, including nested projections
+  and the fields a *renderer* touches. Also check for a field read under a name the producer never
+  emits.
+- **Unresolved values stored as resolved ones.** A promise, a future, a lazy handle or a
+  still-loading state persisted or compared as though it were the settled value. **Probe:** anywhere a
+  value has a "not ready yet" state, find who reads it without checking.
+
+Then the ordinary axes: signed versus unsigned, canonical forms, precision, encoding, equality
+semantics.
+
+**Tell:** a cast, an `any`, a non-null assertion or a suppressed warning at a boundary is where
+contracts go to die - the annotation exists precisely because the two sides disagreed and someone
+silenced the compiler rather than reconciling them. Treat every one of them on a boundary as a
+candidate.
+
+### 11. Ownership, completion and progress
+Trace who may mutate, release, cancel and complete an operation or resource. Inspect exceptional
+exits and competing terminal paths for premature release, missing completion, deadlock, or use after
+ownership changed hands.
+
+### 12. Decisions and dispatch
+Enumerate the meaningful states and inputs for consequential predicates and dispatch tables. Compare
+branches against supported expectations: overlapping conditions, inverted tests, missing cases, and
+what the fallback actually does. Check the *default* a framework or language supplies when the code
+specifies nothing - an unstated default is still a decision.
+
+**Include reachability, not just correctness.** Ask of each consequential branch whether any input
+can reach it, and of each scheduled or registered thing whether anything actually starts it. A
+predicate that can never be true, a handler never wired up, a writer whose output can never reach
+disk, and a job whose scheduler is never started are all defects that read as perfectly correct code.
+They are common in the wild and almost absent from planted corpora, so no checklist trained on
+planted bugs will prompt you to look.
+
+### 13. Verification and observability
+Follow what happens when each step *fails*, and ask what would make the failure visible. Look for
+checks that cannot fail, oracles that measure something other than the thing they claim to,
+exceptions swallowed into a success path, gates that skip their subject, and effects whose absence
+nothing would detect. A step that always passes is not a passing step.
+
+**Probe:** for each guarantee the system claims, name the observation that would break if it stopped
+holding. If there is none, the guarantee is decorative.
+
+> This lens exists because of a gap in the evidence, and the gap is worth stating. A *planted* defect
+> is detectable by construction - somebody planted it, so somebody can find it. Silent failure is
+> therefore systematically absent from planted corpora and heavily represented in real fix histories,
+> where "and nothing noticed" is a recurring phrase. Do not let a benchmark-shaped checklist talk you
+> out of looking here.

+## Using these
+
+- They overlap on purpose. One defect can be lens 1 and lens 3 at once; report the root cause once.
+- Absence of findings under a lens is a valid result. Do not manufacture one to fill the table.
+- Finding nothing under lenses 1 and 2 is worth a second look *only* if you never constructed their
+  probes — a read-through reliably returns nothing here, which is exactly the failure mode.
+- None of these is language- or framework-specific. If a lens seems inapplicable, say which property

+# Sub-case: performance review
+
+A specialisation of the parent engine. The anchor changes; the refutation discipline and the report
+contract do not.
+
+**Anchor:** workload → resource demand → growth or contention → material consequence.
+
+The agreement being tested is between what the code *assumes about its workload* and what the
+workload *will actually be*. Code written against seed data agrees with a world that will not exist
+in production. That is the same shape as any other broken agreement: two participants, each
+reasonable alone.

+## The universal core
+
+Language- and stack-agnostic. Apply before any technology-specific checklist.
+
+- **Repeated work** — scans, parsing, serialisation, allocation, initialisation or I/O performed
+  again where a single pass, a hoist or a reuse would do.
+- **Growth relationships** — how does resource use scale with input size, with concurrency, and with
+  elapsed time? Superlinear growth in any of the three is the finding; the constant factor is not.
+- **Retention** — queues, buffers, caches and collections that grow without a bound, an eviction
+  policy or backpressure. Unbounded retention is a failure with a delay on it.
+- **Copying and conversion** — data copied or converted between representations on a hot path,
+  especially at a boundary where both sides could have agreed on one representation.
+- **Serialisation and contention** — lock duration and scope, single-threaded chokepoints,
+  head-of-line blocking, and work held inside a critical section that did not need to be.
+- **Amplification** — retries, polling, fan-out and cache misses that multiply one logical request
+  into many real ones. Check the multiplier under failure, not under success.
+
+## Technology specialisations
+
+Apply only where the underlying technology exists — do not report the absence of a database concept
+in a program that has no database. For data-backed applications (over-fetching, `SELECT *`, missing
+pagination, index definitions, caching layers), `/performance-audit-static` holds the detailed
+checklist; use it rather than restating it here.
+
+## What makes a performance finding
+
+All three, or it is not a finding:
+
+1. **A reachable workload** — the input size, rate or concurrency is one the system will actually
+   meet, established from the code and its context rather than assumed.
+2. **A resource cost or growth relationship** — what is consumed, and how it scales.
+3. **A material consequence** — latency a user feels, a cost that is paid, a limit that is hit, or a
+   failure that results.
+
+## Refutation
+
+Refute against real bounds, amortisation, reuse, actual call frequency, and deliberate trade-offs. A
+nested loop over a collection with a hard bound of four is not a finding. A missing cache in code
+called once at startup is not a finding.
+
+**Distinguish measurement from static deduction, and label which you did.** Never invent a timing.

+
+**Anchor:** source → trust boundary → sink, with an attacker who controls the source.
+
+The agreement being tested is between what a component *trusts* and what an attacker can *supply*.
+Where correctness asks "can this happen", security asks "can someone make this happen on purpose" —
+and an adversary will construct the unlikely execution deliberately.
+
+## Where the procedure lives
+
+`/security-audit-static` owns the full specialised procedure — entry-point mapping, the four
+high-value paths, the keep/drop rule with its attacker-and-victim test, the OWASP Top 10 coverage
+backstop, and the high-miss checklist. **Run it rather than restating it.** This file exists to say
+what changes when security is selected as a dimension of a code review, and to supply the part of the
+engine that survives when the application has no web surface at all.
+
+## The universal core
+
+Applies to a CLI, a library, a daemon, a build tool — anything without an HTTP handler in sight.
+
+- **Trust boundaries** — every point where data crosses from a less-trusted origin into a
+  more-trusted context: arguments, environment, config files, stdin, filenames, archive members,
+  network responses, plugin and extension surfaces, deserialised state, and model output.
+- **Sinks** — where a value becomes an instruction rather than data: process execution, dynamic
+  evaluation, query construction, path resolution, template rendering, deserialisation, outbound
+  requests, permission and role writes, and logging.
+- **Injection by representation confusion** — a value interpreted in the syntax of the sink rather
+  than as an opaque datum. Encode for the *sink*, not at the input. This is the same disagreement as
+  correctness lens 10 (representation and information loss), with an adversary steering it.
+- **Validator/consumer differentials** — the check and the use disagree about what the value means:
+  unanchored patterns, prefix allowlists, normalisation applied on one side only, validation on one
+  representation and execution on another.
+- **Fail-open paths** — error, timeout, cancellation, cache-miss and boundary branches that default
+  to *allow*. Correctness lens 12 finds these; security decides what they cost.
+- **Secrets and sensitive data in transit to the wrong place** — logs, traces, error bodies,
+  temporary files, crash dumps, and anything an unprivileged local user can read.
+- **Privilege and identity** — which principal an operation runs as, whether the check and the action
+  name the same object, and what happens when they do not.
+
+## The inverted refutation rule
+
+Under correctness, a defect that harms only the person who triggered it is still a defect. Under
+security it usually is **not** a finding: if the only victim is the attacker, on their own machine,
+account, tenant or data, and no shared system or privilege boundary is crossed, drop it.
+
+The carve-outs where that refutation is **forbidden** — outbound-network sinks, shared billing or
+quota, data exposure, cross-tenant or cross-principal flows, and server-side execution or rendering —
+are listed in `/security-audit-static`. Use its list; do not reinvent one.
+
+**Do not let the two rules leak into each other.** Running both dimensions in one review, keep the
+tests separate per finding: a defect dropped as a security finding may still be a correctness finding
+with a real consequence, and should be reported as one.

+## What makes a security finding

+
+1. A supported obligation — the trust assumption, and what establishes it.
+2. A feasible execution — **including who the attacker is and what they control.**
+3. A concrete contradiction — the boundary that fails to hold.
+4. An observable consequence — **naming the victim**, who must not be only the attacker.
+5. An examined counterargument — a real check at the sink, an unreachable path, an upstream
+   validator, or a non-dangerous sink.

Pawel HurynandClaude Opus 5	8607e3b077	Merge origin/main (v2.1.0) into the code-review skill branch Both sides added real content and this merge keeps both rather than picking one. The branch predates the v2.1.0 release, so merging it straight would have REVERTED that release: every plugin.json back from 2.1.0 to 2.0.0, and tests/test_consistency.py and tests/test_validator.py deleted. Merged instead of pushed. Conflicts, all resolved by combining: - pm-ai-shipping/.claude-plugin/plugin.json - v2.1.0's version, the branch's description. - security-audit-static - both checks survive as two steps: verify citations (2.1.0), then report with the OWASP Top 10 coverage backstop (branch). - ship-check - the new correctness review becomes Step 3, and 2.1.0's parallel security + performance pair renumbers to Steps 4 + 5 behind it, keeping the branch's model-mix carry-through on the security bullet. - Notes - 2.1.0's untrusted-input rule and both of the branch's bullets. The v2.1.0 test suite then caught what the branch had missed: a third skill in pm-ai-shipping without the counts to match. Root README headline 68 -> 69 skills, its pm-ai-shipping summary 2 -> 3, and marketplace.json's total and description synced to plugin.json. 15/15 tests and the validator pass. No version bump. The CHANGELOG entry sits under `## Unreleased`, which the tag-on-merge workflow ignores by design, so this lands the skill without cutting a release - that call is Pawel's.

Pawel HurynandClaude Opus 5	c64c2d868d	code-review: state the worker constraints as instructions, not tool permissions A skill cannot restrict a subagent's tools - that is harness configuration, not something SKILL.md can assert. Reframed both worker rules as things the coordinator must SAY in the worker's prompt: name the coordinator's own model explicitly on every spawn and bring in no other model, and tell the worker it is reading rather than editing, then verify the tree is unchanged at the end.

Pawel HurynandClaude Opus 5	76c51f3ae8	code-review: fold in the classes only the natural fix history shows I had only used one repo's per-category survival table plus the other's aggregate numbers, and had not looked at the shipping repos' fix history at all. Reading all 105 planted bugs per-bug, and four weeks of real fixes, changed four things. Taxonomy is now thirteen lenses: - Lens 10 (representation and information loss) is promoted to the highest-frequency class in every corpus and given three named sub-shapes: the nullish family (pending/absent/empty/zero/false/failed collapsing into each other), projection and field-set drift (a producer quietly stops emitting a field, consumers degrade instead of failing), and unresolved values stored as resolved ones. Plus the cast/any/suppression tell - an annotation on a boundary marks where two sides disagreed and someone silenced the compiler. - Lens 12 gains reachability: a predicate nothing can satisfy, a handler never wired, a scheduler never started. Reads as correct code; common in the wild. - Lens 13, verification and observability, is new: the check that cannot fail, the oracle measuring the wrong thing, the effect whose absence nothing would notice. It carries a note on WHY it is new - a planted defect is detectable by construction, so silent failure is systematically absent from planted corpora and heavily represented in real fix histories. A checklist trained only on planted bugs will never prompt you to look here. Refutation gains "absorption is not prevention": a cache that usually holds, a retry that usually succeeds, a default that is usually right - none of those refute a finding, they postpone it. Drop only on a mechanism that makes the execution impossible. Corollary: "works nearly always" describes a race. Parallelism gains two constraints: - One model. Fan-out is for coverage, not a second opinion; workers run the coordinator's model. A single foreign worker makes a measured result unattributable. The independent second-model pass stays where it belongs, as an explicit /ship-check step. - Read-only workers. Read, search, navigate - no writes, edits or mutating commands. A worker that can edit drifts from reviewing into silently fixing, and the tree must end identical to how it started or findings cannot be checked against it.

Pawel HurynandClaude Opus 5	18032bc9f7	pm-ai-shipping: code-review becomes the top-level skill; perf + security are sub-cases Restructure, per the ask that code review be the parent and the other two dimensions its sub-cases: - SKILL.md gains a "one engine, three anchors" section. Correctness is the core and stays inline; performance and security move to their own reference files, loaded only when selected. - references/performance-review.md (new) — a universal, stack-agnostic core (repeated work, growth relationships, retention, copying, contention, amplification) plus the three-part bar for a performance finding. Defers the database/web checklist to /performance-audit-static instead of restating it. - references/security-review.md (new) — trust boundaries and sinks for code with no web surface, and the one rule that INVERTS relative to correctness: attacker-equals-victim refutes a security finding but never a correctness one. Defers the full procedure to /security-audit-static. - Both audit commands now say they are the specialisation behind their sub-case, so the narrow entry points still lead back to the skill. ship-check gains two stages it was missing: - Step 3, correctness review — the pass neither audit performs: logic and state defects that compile clean and pass the suite. - Step 6, independent unsteered review — a fresh session of a second model (Codex or equivalent), given no checklist and no prior findings, with the subject computed from a diff rather than described. Every finding is hand-verified against the code before it enters the packet, since an unsteered reviewer carries no refutation discipline of its own. The packet reports whether it ran clean or did not run at all - those are different signals. Also carries the working-tree edits already in progress: model-and-orchestration guidance on both audits, the OWASP A02/A06/A09 backstop, CSP in the output-encoding bullet, the prompt-injection/agent-abuse bullet, and the Audit Provenance section (now also naming the second model). No version bump - not tested against the benchmark yet. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> Claude-Session: https://claude.ai/code/session_01G42vsxSKL7je39AsHZ5aJm	2026-09-13 15:15:57 +02:00
Pawel HurynandClaude Opus 5	2e662ac04d	pm-ai-shipping: add the code-review skill (correctness / performance / security, each optional) NOT RELEASED. No version bump - versions stay at 2.0.0 across all 9 plugins and marketplace.json, because bumping is the release action and this ships only after it has been tested. On a branch for the same reason. WHY A SKILL AND NOT A FOURTH COMMAND. /security-audit-static is already mature - sink analysis, self-refutation with attacker/victim rules, OWASP backstop, fan-out. Rebuilding that inside something new would duplicate it. The hole in this plugin is CORRECTNESS: there is no bug-finding review at all. So this is one skill with three independently activated dimensions that defers to the existing command for security and points at intended-vs-implemented for the doc-vs-code axis. THE ANCHOR IS THE AGREEMENT, NOT THE FILE. The defects reviewers miss are rarely visible inside one file - they are disagreements between two participants that each read sensibly alone. Engine: map a flow, identify an obligation, inspect EVERY participant, construct a violating execution, trace the consequence, refute, report. Two lenses get a forced probe rather than a checklist mention: authority reconciliation (a requested value is not an applied value) and identity correlation (is the key unique, stable and live under overlap and reuse). Refutation discipline is deliberately stricter than the security command's: a correctness defect can harm only the person who triggered it and still be serious, so the attacker/victim test does not transfer, and 'keep unless disproved' is too permissive. Keep / Drop / Unresolved, with unresolved kept out of the findings list. Parallelism fans out over complete flows, never over files - partitioning by file is exactly the split that hides cross-boundary defects. Overlapping reads are allowed and encouraged. Coverage reports work performed in four states; zero findings is not 'not covered'. Co-designed with GPT-6 Astra (Codex CLI). Contains no project-specific content: no repo names, no paths, no bug identifiers, no defect text - verified by scan.
