 Prettier owns formatting. Run `make fmt` before committing; `make fmt-check` gates CI.
 
-## Task branches
+Everything in `scripts/` is TypeScript run directly by Node (`node scripts/foo.ts`) — Node 24 strips the
+types, so those files must stay within erasable syntax and must not use APIs newer than the `lib` in
+`tsconfig.json`. `scripts/tsconfig.json` enforces both.

-- Adding or moving a test, regenerating checked-in generated fixtures, running the local gate, reading a
-  coverage or drift failure, or changing managed-D1 scenarios: `docs/agents/verification.md`.
-- Preparing a release, changing `.github/workflows/release.yml`, or touching candidate identity, the release
-  manifest, or the R2 publication contract: `docs/agents/release.md`.

-### Issue tracker
+**The runtime is shipped text.** Only the lines between `// --- RUNTIME BEGIN ---` and `// --- RUNTIME END ---`
+in `src/runtime.d1.ts` reach consumers; `scripts/runtime-text-plugin.ts` inlines them as a string literal at
+build time. Reformatting or reindenting inside the markers changes the bytes every consumer receives, which is
+why the file is excluded from the root `tsconfig.json` and compiled only through the generated fixtures. Follow
+any edit with a rebuild and a fixture regeneration.
 
-Issues are tracked in this repository’s GitHub Issues. See `docs/agents/issue-tracker.md`.
+**Public versus private surface.** The public surface is what `test/types/consumer.ts` compiles against and
+what `docs/generated-code-tour.md` shows. Query descriptor internals, row parsers, generated private aliases,
+and `generatedInternals` members are private and may change freely.
 
-### Triage labels
+**Diagnostics are an identifier contract.** The `[CATEGORY/REASON]` strings produced by `src/diagnostics.ts`
+are public and documented in `docs/troubleshooting.md`. A diagnostic carries metadata locations — query name,
+column, position — and describes the shape of what it rejected; SQL text and bind values stay out of it.
 
-The tracker uses the default five-role triage vocabulary. See `docs/agents/triage-labels.md`.
+**Runtime error classes are a contract.**
 
-### Domain docs
+- `QueryArgumentError` — the arguments failed validation and D1 was never called.
+- `QueryUsageError` — a query descriptor or an executor was used in a way the API forbids.
+- `QueryResultError` — D1 succeeded and row mapping failed.
 
-This is a single-context repository. See `docs/agents/domain.md`.
+Native D1 errors pass through unwrapped, so a consumer can recognize them. A `QueryResultError` raised after a
+write means the write happened and the mapping failed; it is not evidence of a rollback.
+
+**Fail closed at the compatibility surface.** Metadata the plugin cannot translate safely produces a diagnostic
+and stops generation with no partial tree, rather than an approximated result shape or an unsafe cast.
+
+## Verification
+
+**One publication candidate, supplied everywhere.** Every exact-candidate target takes `CANDIDATE_WASM` and
+`CANDIDATE_SHA256` as 64 lowercase hex characters, and refuses to run without both. Pass the candidate path
+absolute: the sub-project targets run from their own directories and resolve it there. `make verify-local` is
+the only target that builds a candidate: it removes prior build output, builds once, and delegates to
+`make verify-candidate` with the digest it computed.
+
+Evidence binds to bytes. A rebuild partway through a gate invalidates every result already collected, because
+the collected results then describe two artifacts rather than one.
+
+The layers, each answering a different question about the same candidate: `generator` (pure request-to-file
+behavior), `types` (public-only strict compilation on the floor and current TypeScript), `candidate` (the same
+generator scenarios through the real WASM), `verification` (contracts over manifests, scripts, and workflow
+text), `miniflare` (isolated D1 with fresh storage per test), `example` (the canonical Worker), and
+`managed-d1` (real D1 seams only a live account can show).
+
+Adding a root test file means adding it to `ROOT_TESTS` and its bundle to `ROOT_DIST` in the `Makefile`, and to
+`include` in `test/tsconfig.json`.
+
+**Checked-in generated output and drift.** `test/miniflare/src/` and `examples/d1-worker/src/` hold plugin
+output. The hand-written `index.ts` in each is the only exception, and `scripts/check-generated-drift.ts`
+preserves them during regeneration. `.prettierignore` lists the emitted files because `make
+test-generated-drift` compares them byte for byte.
+
+`--mode mirror` regenerates into a temporary copy and leaves the worktree untouched. `--mode worktree`
+regenerates in a detached `git worktree` at `HEAD` and asserts `git status --porcelain` is empty. Both write
+the retained candidate to a `0400` temporary file and clean up unconditionally. Both need `sqlc` on `PATH`.
+
+**Regenerating the fixtures:**
+
+```
+make build
+SHA=$(shasum -a 256 build/plugin.wasm | awk '{print $1}')
+for dir in test/miniflare examples/d1-worker; do
+  node scripts/generate-candidate.ts --candidate "$PWD/build/plugin.wasm" --sha256 "$SHA" --config sqlc.yaml --cwd "$PWD/$dir"
+done
+```
+
+**Sub-project formatting.** `examples/d1-worker/` and `test/miniflare/` are bun sub-projects that keep their
+own Prettier configuration; Prettier resolves configuration per file, so their hand-written sources stay
+tab-indented. Use bun inside those directories.
+
+**Compatibility configuration is authoritative.** `verification/compatibility.json` is the only home for the
+sqlc samples and their rationale, the known exceptions, the TypeScript floor and current versions, the exact
+Cloudflare baseline, and the exact tool versions. `scripts/compatibility-config.ts` reads it,
+`scripts/workflows/emit-compatibility-outputs.ts` feeds workflows from it, and `docs/compatibility.md`
+presents it to consumers. Change the JSON; every other copy is derived.
+
+**Decided, against the obvious default:** sqlc is sampled strategically — the floor, the tested ceiling, and
+the intervening releases tied to a material protocol or metadata change. A matrix over every sqlc minor was
+considered and rejected ([#13](https://github.com/mkuznets/sqlc-d1-typescript/issues/13),
+[#38](https://github.com/mkuznets/sqlc-d1-typescript/issues/38)).
+
+## Managed D1 creates real resources
+
+Managed-D1 runs provision live Cloudflare resources under the reserved name grammar
+`sqlc-d1-ci-yyyymmddthhmmssz-<run-id>-<attempt>-<8-lower-hex>` (`RESOURCE_NAME_PATTERN` in
+`scripts/managed-d1-contract.ts`). Exact resource identifiers are persisted the moment they exist, primary
+cleanup runs unconditionally and reports separately from the test outcome, and **a cleanup failure is a failed
+release gate even when emergency recovery succeeds**. The weekly reaper (`make reap-managed-d1`) deletes only
+complete reserved names strictly older than 24 hours. Stateful scenarios run once; diagnose a failure rather
+than retrying it.
+
+Scenario ids are compiled in as `MANAGED_SCENARIO_IDS` in `scripts/managed-d1-contract.ts`. The deployed
+endpoint accepts those ids and returns scenario outcomes; SQL, bind values, and expected rows stay out of the
+protocol in both directions. Operations, the protected Environment, token scopes, and the audit checklist live
+in `docs/managed-d1-verification.md`.
+
+## Sensitive data stays inside the run
+
+Evidence, logs, artifacts, and issues carry candidate identity, configuration, scenario outcomes, exact
+resource identifiers, and cleanup facts. SQL text, bind values, result rows, session bookmarks, authorization
+headers, tokens, Cloudflare credentials, stack traces, error causes, and response bodies stay in the run that
+produced them. `inspectKeys` in `scripts/managed-d1-contract.ts` enforces this for managed evidence by
+rejecting any key outside its allow-list. Secret identifiers and minimum permission scopes are documentable;
+their values live only in the Environment.
+
+## Release
+
+`.github/workflows/release.yml` validates release intent, builds one publication candidate, runs the
+uncredentialed gates, calls managed-D1 verification through `.github/workflows/_managed-d1.yml`, assembles the
+release manifest, and then publishes.
+
+**A valid tag is the approval.** A strict SemVer `v*` tag on default-branch lineage is the maintainer's release
+approval, and it is the only one. There is no dry-run mode: to rehearse a release, cut the next patch version.
+**Decided, against the obvious default:** an additional required-reviewer click was considered and rejected;
+the `managed-d1` Environment is protected by ref and tag restrictions with no reviewer and no wait timer
+([#17](https://github.com/mkuznets/sqlc-d1-typescript/issues/17),
+[#40](https://github.com/mkuznets/sqlc-d1-typescript/issues/40)).
+
+**One candidate per run.** The `candidate` job builds exactly once per run and retains the bytes as
+`publication-candidate-<run_id>`. Every downstream job, the credentialed managed-D1 job included, downloads by
+artifact id and verifies the full SHA-256 before use. Evidence from one run describes one artifact, so a pass
+is assembled from a single run's evidence.
+
+**Publication order is the safety property.** R2 first, then the public origin is re-downloaded and compared to
+the candidate, then the GitHub Release is cut — the release notes may only advertise a URL that already serves
+the right bytes. The R2 write uses `--if-none-match '*'`, so a version key can never be replaced once
+published. `contents: write` appears on the `publish` job and nowhere else, and
+`test/verification-contracts.test.ts` holds the workflow to that. Operations live in
+`docs/release-publication.md`.
+
+**Canonical names.** `sqlc-gen-d1-typescript_<version>.wasm` and
+`sqlc-gen-d1-typescript_<version>.manifest.json`, with no aliases. The permanent artifact URL shape and the
+manifest contract live in `scripts/release-contract.ts`.
+
+## GitHub Actions workflows
+
+A `run:` block holds plain bash: a handful of commands, `test` and `echo` guards, and invocations of scripts.
+Anything beyond a few lines of bash goes into a file under `scripts/workflows/` that the workflow calls. Pass
+workflow values in through `env:` rather than interpolating `${{ }}` into the middle of a script. Shared
+helpers live in `scripts/workflows/lib.sh` for bash (`log`, `detail`, `warn`, `fail`) and
+`scripts/workflows/step.ts` for TypeScript (`fail`, `flagValue`, `writeStepOutputs`).
+
+Every job and step carries a `name:` that says what it does, announces what it is about to do and what it
+observed, and fails with a `::error::` annotation that says what failed **and what that means**. A bare
+`test a = b` guard that fails silently leaves the reader with an exit code and nothing else.
+
+The scripts the `intent` job runs execute before any job has run `npm ci`, so they must import only `node:`
+builtins and each other. `test/verification-contracts.test.ts` walks that import graph and enforces it.
+
+## Consumer skill
+
+`skills/sqlc-d1-typescript/` is the one thing here that leaves the repository and runs in a consumer's
+workspace. It promises one run, from a fresh consumer workspace to verified local behavior: bind to one
+release, write the sqlc configuration, generate, wire the Workers binding interface, typecheck, and pass one
+focused local D1 test. Then it reports and stops. Deployment, remote bindings, live D1 resources, and every
+Cloudflare credential are outside that promise and stay outside it.
+
+The skill ships inside the tagged tree. The install command in `README.md` clones the tag and writes it into
+`INSTALLED_TAG` in the consumer's workspace; step 1 of the skill reads that stamp, compares it to the version
+in the consumer's sqlc configuration, and stops on a mismatch. No version fact belongs in `SKILL.md` or its
+`reference/` files — they are fetched from the release record and from tag-pinned `docs/`.
+
+**Decided, against the obvious default:** a committed `VERSION` file under `skills/` was rejected — this
+repository publishes nothing at tag time, so it would need a hand bump before every tag and would be wrong on
+the default branch between releases ([#43](https://github.com/mkuznets/sqlc-d1-typescript/issues/43)).
+

-# sqlc D1 TypeScript
-
-A sqlc code-generation plugin that produces type-safe TypeScript for executing analyzed SQLite queries through Cloudflare Workers D1 bindings.
-
-## Language
-
-**Plugin**:
-The sqlc WASM component that translates sqlc’s analyzed SQLite query metadata into D1-oriented TypeScript.
-_Avoid_: Extension, driver
-
-**Workers binding interface**:
-The supported integration boundary in which generated code executes through a Cloudflare Worker’s `D1Database` or D1 session binding.
-_Avoid_: D1 HTTP API, Node SQLite interface
-
-**Query descriptor**:
-A typed description of one generated query invocation that can be passed to a query executor individually or in a batch.
-_Avoid_: Executed query, prepared statement
-
-**Query executor**:
-The generated runtime-facing API that executes query descriptors through a D1 database or session binding.
-_Avoid_: Database driver
-
-**Session executor**:
-A request-flow-local query executor backed by a D1 session, providing D1 session consistency and access to the latest session bookmark.
-_Avoid_: Persistent session, transaction
-
-**Session bookmark**:
-An opaque D1 string transferred between session executors to continue a consistency constraint across requests.
-_Avoid_: Session executor, authentication token
-
-**Compatibility surface**:
-The sqlc SQLite commands, macros, metadata shapes, and D1 value representations that the plugin promises to translate correctly.
-_Avoid_: Every SQLite feature
-
-**Bind value**:
-A TypeScript value accepted by a query factory for conversion to a parameter representation supported by the Workers binding interface.
-_Avoid_: Arbitrary JavaScript value
-
-**Row mapping**:
-The compatibility-surface conversion from a D1 result object's physical fields into a generated public query row.
-_Avoid_: Type assertion
-
-**Release gate**:
-The explicit evidence and checks required before publishing a plugin release as trustworthy for experienced sqlc and Cloudflare users.
-_Avoid_: Done, production-ready
-
-**Publication candidate**:
-The exact plugin WASM bytes selected for a version and evaluated by the release gate before becoming publicly advertised.
-_Avoid_: Rebuild, latest build
-
-**Published artifact**:
-A publication candidate made available at its permanent versioned URL and identified by its SHA-256.
-_Avoid_: Latest artifact, replaceable release
-
-**Version key**:
-The permanent object-storage key assigned to one plugin version; retries may confirm its bytes but never replace them.
-_Avoid_: Latest key, release channel
-
-**Release record**:
-The public metadata that connects a version and source commit to the published artifact's URL and SHA-256.
-_Avoid_: Artifact, changelog alone

-# Consumer skill
-
-The branch for changing the consumer skill under `skills/sqlc-d1-typescript/` or the installation guidance in
-`README.md`.
-
-Everything else under `docs/agents/` addresses an agent changing **this** repository. This one document
-addresses an agent changing what a **consumer's** agent reads: the skill is the only material here that leaves
-the repository and runs somewhere else.
-
-## What the skill promises
-
-One run, from a fresh consumer workspace to verified local behavior: bind to one release, write the sqlc
-configuration, generate, wire the Workers binding interface, typecheck, and pass one focused local D1 test.
-Then it reports and stops.
-
-The stopping point is the promise. Deployment, remote bindings, live D1 resources, and every Cloudflare
-credential are outside it, and stay outside it. Nothing the skill drives needs an account.
-
-## Tag-matched installation
-
-A valid SemVer `v*` tag on default-branch lineage is the maintainer's release approval, so the tag that
-authorizes a version is also the object a consumer can install the skill from. The skill ships inside the
-tagged tree and adds no publication object: the contract stays one WASM artifact and one release manifest per
-version, at the canonical filenames `scripts/release-contract.mjs` fixes.
-
-The install command in `README.md` clones the tag and writes the tag it cloned into `INSTALLED_TAG` in the
-consumer's workspace. Step 1 of the skill reads that stamp, compares it to the version in the consumer's sqlc
-configuration, and stops on a mismatch.
-
-**Decided, against the obvious default:** a committed `VERSION` file under `skills/` was rejected — this
-repository publishes nothing at tag time, so such a file would need a hand bump before every tag and would be
-wrong on the default branch between releases. Asking the human which tag they installed was rejected too: it
-is unverifiable, and it pushes a correctness check onto the one party with no way to answer it. The install
-command is the only moment the tag is known for certain, so the install command writes it.
-`test/consumer-skill.test.ts` asserts the repository ships no `INSTALLED_TAG` of its own, so a stale stamp can
-never reach a consumer.
-
-## Three tiers, and what may live in each
-
-| Tier                                      | Owns                                                           |
-| ----------------------------------------- | -------------------------------------------------------------- |
-| `skills/sqlc-d1-typescript/SKILL.md`      | The ordered process, completion criteria, fail-closed rules.   |
-| `skills/sqlc-d1-typescript/reference/`    | Branch-conditional detail: failure routing, local test wiring. |
-| Tag-pinned `docs/` and the release record | Every version-specific fact.                                   |
-
-No version fact belongs in the first two tiers. The supported sqlc range, the TypeScript evidence, the exact
-Cloudflare baseline, the artifact digest, and the compatibility surface are fetched from the release record and
-from the human documentation pinned to the installed tag's `blob` URLs, never copied down. A skill file
-containing a `MAJOR.MINOR` literal fails the gate, exactly as a maintainer guidance file does.
-
-Reference files are disclosed, not inlined, because they are genuine branches: most runs never hit a
-diagnostic, and a project that already tests its Worker never opens the local-test wiring.
-
-## What the gate enforces
-
-`test/consumer-skill.test.ts` is static, candidate-free, and runs inside `make test-generator`. It reads its
-expectations out of source rather than restating them, so changing the Plugin fails the skill's gate instead of
-silently invalidating the skill:
-
-- diagnostic phases against `DiagnosticCategory` in `src/diagnostics.ts`, all of them covered;
-- runtime error classes and the safe context fields against the shipped runtime in `src/runtime.d1.ts`;
-- the install command the skill quotes at its mismatch stop against the one in `README.md`, line for line;
-- the option surface against `src/validation.ts` — `interface: workers` and nothing else;
-- snippet imports and SQL against the canonical Worker in `examples/d1-worker/`;
-- the artifact URL, the manifest filename, and the digest shape against `scripts/release-contract.mjs` and
-  `verification/release-manifest.schema.json`;
-- every repository link pinned to the installed tag and resolving to a path that exists today;
-- the vocabulary fixed by `CONTEXT.md`;
-- no version literal, no credential, no deployment, no runtime interface other than the Workers binding
-  interface.
-
-Adding a file under `skills/sqlc-d1-typescript/` requires a pointer to it from another skill file; the gate
-rejects orphans.
-
-## Validating a change to the skill
-
-The gate is static. Before shipping a change to the skill's procedure, run it end to end from a workspace
-outside this repository, against a locally built candidate:
-
-```
-make build
-SHA=$(shasum -a 256 build/plugin.wasm | awk '{print $1}')
-WORK=$(mktemp -d)
-mkdir -p "$WORK/.claude/skills"
-cp -R skills/sqlc-d1-typescript "$WORK/.claude/skills/"
-printf 'v0-validation\n' >"$WORK/.claude/skills/sqlc-d1-typescript/INSTALLED_TAG"
-```
-
-Then follow `skills/sqlc-d1-typescript/SKILL.md` inside `$WORK` with two maintainer-side substitutions, neither
-of them part of the shipped guidance: step 1's release record becomes the retained candidate (`url:` a `file:`
-URL for the built WASM, `sha256:` the digest above, version-match satisfied by the stamp), and the
-version-specific facts step 1 would read from the release record come from the working tree's
-`docs/compatibility.md`. Everything from step 2 onward runs unmodified. Use the canonical schema and queries
-from `examples/d1-worker/` so the generated output can be compared with the checked-in canonical tree — the
-same `file:` URL substitution `scripts/generate-candidate.mjs` performs for fixtures.
-
-Exercise both fail-closed paths in the same run: a mismatched `INSTALLED_TAG`, and an input the Plugin refuses.
-Each must stop and report rather than degrade.
-
-No published artifact exists until [#44](https://github.com/mkuznets/sqlc-d1-typescript/issues/44) lands, so
-the skill's HTTPS path to a release record cannot be exercised before the first tag. That is an accepted
-assumption of the design, not an oversight.
-
-## Decisions governing this area
-
-Read the issue rather than re-deriving the decision:
-[#15](https://github.com/mkuznets/sqlc-d1-typescript/issues/15) (repository-agent guidance and the consumer
-skill boundary), [#16](https://github.com/mkuznets/sqlc-d1-typescript/issues/16) (the immutable release
-contract), [#43](https://github.com/mkuznets/sqlc-d1-typescript/issues/43) (the tag-matched consumer skill).
-
-When the change also touches a test registration, `docs/agents/verification.md` carries the coverage rules.

-# Domain Docs
-
-How the engineering skills should consume this repo's domain documentation when exploring the codebase.
-
-## Before exploring, read these
-
-- **`CONTEXT.md`** at the repo root, or
-- **`CONTEXT-MAP.md`** at the repo root if it exists — it points at one `CONTEXT.md` per context. Read each one relevant to the topic.
-- **`docs/adr/`** — read ADRs that touch the area you're about to work in. In multi-context repos, also check `src/<context>/docs/adr/` for context-scoped decisions.
-
-If any of these files don't exist, **proceed silently**. Don't flag their absence; don't suggest creating them upfront. The `/domain-modeling` skill creates them lazily when terms or decisions actually get resolved.
-
-## File structure
-
-Single-context repo (most repos):
-
-```
-/
-├── CONTEXT.md
-├── docs/adr/
-│   ├── 0001-event-sourced-orders.md
-│   └── 0002-postgres-for-write-model.md
-└── src/
-```
-
-Multi-context repo (presence of `CONTEXT-MAP.md` at the root):
-
-```
-/
-├── CONTEXT-MAP.md
-├── docs/adr/                          ← system-wide decisions
-└── src/

-    └── billing/
-        ├── CONTEXT.md
-        └── docs/adr/
-```
-
-## Use the glossary's vocabulary
-
-When your output names a domain concept (in an issue title, a refactor proposal, a hypothesis, a test name), use the term as defined in `CONTEXT.md`. Don't drift to synonyms the glossary explicitly avoids.
-
-If the concept you need isn't in the glossary yet, that's a signal — either you're inventing language the project doesn't use (reconsider) or there's a real gap (note it for `/domain-modeling`).
-
-## Flag ADR conflicts
-
-If your output contradicts an existing ADR, surface it explicitly rather than silently overriding:
-
-> _Contradicts ADR-0007 (event-sourced orders) — but worth reopening because…_

-## The runtime is shipped text
-
-Only the lines between `// --- RUNTIME BEGIN ---` and `// --- RUNTIME END ---` in `src/runtime.d1.ts` reach
-consumers; `scripts/runtime-text-plugin.mjs` inlines them as a string literal at build time. Reformatting or
-reindenting inside the markers changes the bytes every consumer receives, which is why the file is excluded
-from the root `tsconfig.json` and compiled only through the generated fixtures. Follow any edit with a rebuild
-and a fixture regeneration — `docs/agents/verification.md` owns that procedure.
-
-## Public versus private surface
-
-The public surface is what `test/types/consumer.ts` compiles against and what `docs/generated-code-tour.md`
-shows. Query descriptor internals, row parsers, generated private aliases, and `generatedInternals` members
-are private and may change freely. Changing the public surface changes the type fixtures, the consumer
-documentation, and `verification/coverage-manifest.json` in the same change.
-
-## Diagnostics are an identifier contract
-
-The `[CATEGORY/REASON]` strings produced by `src/diagnostics.ts` are public and documented in
-`docs/troubleshooting.md`. A diagnostic carries metadata locations — query name, column, position — and
-describes the shape of what it rejected; SQL text and bind values stay out of it. Adding one means adding a
-matching `diagnostic-*` promise to `verification/coverage-manifest.json`, which the surface inventory in
-`test/verification-contracts.test.ts` asserts.
-
-## Runtime error classes are a contract
-
-- `QueryArgumentError` — the arguments failed validation and D1 was never called.
-- `QueryUsageError` — a query descriptor or an executor was used in a way the API forbids.
-- `QueryResultError` — D1 succeeded and row mapping failed.
-
-Native D1 errors pass through unwrapped, so a consumer can recognize them. A `QueryResultError` raised after a
-write means the write happened and the mapping failed; it is not evidence of a rollback.
-
-## Fail closed at the compatibility surface
-
-Metadata the Plugin cannot translate safely produces a diagnostic and stops generation with no partial tree,
-rather than an approximated result shape or an unsafe cast. A consumer reads a hard failure at generation time
-as an honest limit; an unsound type is discovered in production.
-
-## Decisions governing this area
-
-Read the issue rather than re-deriving the decision:
-[#7](https://github.com/mkuznets/sqlc-d1-typescript/issues/7) (generated-code public model),
-[#8](https://github.com/mkuznets/sqlc-d1-typescript/issues/8) (command and macro semantics),
-[#9](https://github.com/mkuznets/sqlc-d1-typescript/issues/9) (type, value, and row-mapping semantics),
-[#10](https://github.com/mkuznets/sqlc-d1-typescript/issues/10) (batching and sessions),
-[#11](https://github.com/mkuznets/sqlc-d1-typescript/issues/11) (runtime error contract),
-[#19](https://github.com/mkuznets/sqlc-d1-typescript/issues/19) (safe emission and naming),
-[#20](https://github.com/mkuznets/sqlc-d1-typescript/issues/20) (boundary validation and diagnostics).
-
-## Finishing
-
-`docs/agents/verification.md` carries the primary owner rule for the behavior you changed, the regeneration
-procedure for the checked-in fixtures, and the exact-candidate rule that governs the gate. `AGENTS.md` carries
-the `make fmt` reminder that applies to every commit.

-When set to `yes`, PRs run through the same labels and states as issues, using the `gh pr` equivalents:
-
-- **Read a PR**: `gh pr view <number> --comments` and `gh pr diff <number>` for the diff.
-- **List external PRs for triage**: `gh pr list --state open --json number,title,body,labels,author,authorAssociation,comments` then keep only `authorAssociation` of `CONTRIBUTOR`, `FIRST_TIME_CONTRIBUTOR`, or `NONE` (drop `OWNER`/`MEMBER`/`COLLABORATOR`).
-- **Comment / label / close**: `gh pr comment`, `gh pr edit --add-label`/`--remove-label`, `gh pr close`.
-
-GitHub shares one number space across issues and PRs, so a bare `#42` may be either — resolve with `gh pr view 42` and fall back to `gh issue view 42`.
-
-## When a skill says "publish to the issue tracker"
-
-Create a GitHub issue.
-
-## When a skill says "fetch the relevant ticket"
-
-Run `gh issue view <number> --comments`.
-
-## Wayfinding operations
-
-Used by `/wayfinder`. The **map** is a single issue with **child** issues as tickets.
-
-- **Map**: a single issue labelled `wayfinder:map`, holding the Notes / Decisions-so-far / Fog body. `gh issue create --label wayfinder:map`.
-- **Child ticket**: an issue linked to the map as a GitHub sub-issue (`gh api` on the sub-issues endpoint). Where sub-issues aren't enabled, add the child to a task list in the map body and put `Part of #<map>` at the top of the child body. Labels: `wayfinder:<type>` (`research`/`prototype`/`grilling`/`task`). Once claimed, the ticket is assigned to the driving dev.
-- **Blocking**: GitHub's **native issue dependencies** — the canonical, UI-visible representation. Add an edge with `gh api --method POST repos/<owner>/<repo>/issues/<child>/dependencies/blocked_by -F issue_id=<blocker-db-id>`, where `<blocker-db-id>` is the blocker's numeric **database id** (`gh api repos/<owner>/<repo>/issues/<n> --jq .id`, _not_ the `#number` or `node_id`). GitHub reports `issue_dependencies_summary.blocked_by` (open blockers only — the live gate). Where dependencies aren't available, fall back to a `Blocked by: #<n>, #<n>` line at the top of the child body. A ticket is unblocked when every blocker is closed.
-- **Frontier query**: list the map's open children (`gh issue list --state open`, scoped to the map's sub-issues / task list), drop any with an open blocker (`issue_dependencies_summary.blocked_by > 0`, or an open issue in the `Blocked by` line) or an assignee; first in map order wins.
-- **Claim**: `gh issue edit <n> --add-assignee @me` — the session's first write.
-- **Resolve**: `gh issue comment <n> --body "<answer>"`, then `gh issue close <n>`, then append a context pointer (gist + link) to the map's Decisions-so-far.

-# Release
-
-The branch for preparing a release, changing the release spine, and touching candidate identity, the release
-manifest, or the R2 publication contract.
-
-## What the spine does today
-
-`.github/workflows/release.yml` validates release intent, builds or reuses one publication candidate, runs the
-uncredentialed gates, calls managed-D1 verification through `.github/workflows/_managed-d1.yml`, assembles the
-release manifest, and then publishes.
-
-Publication is one process, `scripts/publish-release.mjs`, and its order is the safety property: draft release,
-assets, create-only R2 write, independent downloads of every surface, and the GitHub Release published last.
-Nothing else in the workflow writes anywhere; `contents: write` appears on the `publish` job and nowhere else,
-and `test/verification-contracts.test.ts` holds the workflow to that. Operations, the protected Environment,
-token scopes, the dry-run procedure, and the recovery playbook live in `docs/release-publication.md`.
-
-The workflow still creates no tag. A dry run rehearses the whole path against the real accounts using a
-rehearsal object key and a draft name that can never become a tag, then deletes both.
-
-## A valid tag is the approval
-
-A strict SemVer `v*` tag on default-branch lineage is the maintainer's release approval, and it is the only
-one. **Decided, against the obvious default:** an additional required-reviewer click was considered and
-rejected; the `managed-d1` Environment is protected by ref and tag restrictions with no reviewer and no wait
-timer ([#17](https://github.com/mkuznets/sqlc-d1-typescript/issues/17),
-[#40](https://github.com/mkuznets/sqlc-d1-typescript/issues/40)). Keep the path from tag to evidence
-click-free.
-
-## One candidate per run
-
-The `candidate` job builds exactly once per workflow run and retains the bytes as
-`publication-candidate-<run_id>`. A rerun (`github.run_attempt` above one) reuses those bytes by numeric
-artifact id, and the reuse path is asserted to contain no build step. Every downstream job, the credentialed
-managed-D1 job included, downloads by artifact id and verifies the full SHA-256 before use.
-
-An infrastructure failure is rerun against the retained candidate inside the same run. Evidence from one run
-describes one artifact, so a pass is assembled from a single run's evidence.
-
-## Canonical names
-
-`sqlc-gen-d1-typescript_<version>.wasm` and `sqlc-gen-d1-typescript_<version>.manifest.json`, with no aliases:
-`test/verification-contracts.test.ts` asserts the earlier generic name, release-manifest.json, appears nowhere
-in the workflow. The permanent artifact URL shape and the manifest contract live in
-`scripts/release-contract.mjs` and `verification/release-manifest.schema.json`.
-
-## The permanent version-key boundary
-
-Before the R2 version key for a version exists, that version is still free: a failed tag may be deleted and
-recreated at the same version after fixing source, workflow, or configuration.
-
-Once the key exists, the version is permanently bound to those bytes, because the public URL may already be
-cached anywhere. A later retry re-uploads the exact retained bytes; any change to the artifact requires a new
-version. Publication is create-only (`If-None-Match: *`), and a `412` on an existing key is acceptable only
-after verifying full-byte identity.
-
-This is live behavior, not a plan. `scripts/publish-release.mjs` writes the key, then proves the artifact by
-downloading it from the S3 endpoint and again from the public URL unauthenticated, and only then publishes.
-Every failure names the phase and the recovery that applies to the side of the boundary it reached.
-
-**Decided, against the obvious default:** burning the version on any failed tag was considered and rejected
-([#16](https://github.com/mkuznets/sqlc-d1-typescript/issues/16),
-[#17](https://github.com/mkuznets/sqlc-d1-typescript/issues/17),
-[#44](https://github.com/mkuznets/sqlc-d1-typescript/issues/44)).
-
-## Agents prepare; the maintainer tags
-
-Prepare the change, run the gates that need no credentials, state precisely what remains, and hand the tag
-decision to the maintainer. Tag creation, tag movement, tag deletion, GitHub Releases, and publication
-workflows are the maintainer's to run.
-
-## Credentials
-
-Secret identifiers and minimum permission scopes are documented in `docs/managed-d1-verification.md` and
-`docs/release-publication.md`. Their values live only in the protected Environments.
-
-## Decisions governing this area
-
-Read the issue rather than re-deriving the decision:
-[#16](https://github.com/mkuznets/sqlc-d1-typescript/issues/16) (immutable R2 release contract),
-[#17](https://github.com/mkuznets/sqlc-d1-typescript/issues/17) (release gate),
-[#39](https://github.com/mkuznets/sqlc-d1-typescript/issues/39) (exact-artifact release spine),
-[#44](https://github.com/mkuznets/sqlc-d1-typescript/issues/44) (immutable GitHub and R2 publication).
-
-The gate the spine runs is described in `docs/agents/verification.md`; when the change lands in a workflow
-file, `docs/agents/workflows.md` carries the authoring rules.

-# Triage Labels
-
-The skills speak in terms of five canonical triage roles. This file maps those roles to the actual label strings used in this repo's issue tracker.
-
-| Label in mattpocock/skills | Label in our tracker | Meaning                                  |
-| -------------------------- | -------------------- | ---------------------------------------- |
-| `needs-triage`             | `needs-triage`       | Maintainer needs to evaluate this issue  |
-| `needs-info`               | `needs-info`         | Waiting on reporter for more information |
-| `ready-for-agent`          | `ready-for-agent`    | Fully specified, ready for an AFK agent  |
-| `ready-for-human`          | `ready-for-human`    | Requires human implementation            |
-| `wontfix`                  | `wontfix`            | Will not be actioned                     |
-
-When a skill mentions a role (e.g. "apply the AFK-ready triage label"), use the corresponding label string from this table.
-
-Edit the right-hand column to match whatever vocabulary you actually use.

-# Verification
-
-The branch for adding or moving a test, regenerating checked-in generated fixtures, running the local gate,
-reading a coverage or drift failure, and changing managed-D1 scenarios.
-
-## One publication candidate, supplied everywhere
-
-Every exact-candidate target takes `CANDIDATE_WASM` and `CANDIDATE_SHA256` as 64 lowercase hex characters, and
-refuses to run without both. Pass the candidate path absolute: the sub-project targets run from their own
-directories and resolve it there. `make verify-local` is the only target that builds a
-candidate: it removes prior build output, builds once, and delegates to `make verify-candidate` with the
-digest it computed. Everything downstream consumes those bytes.
-
-Evidence binds to bytes. A rebuild partway through a gate invalidates every result already collected, because
-the collected results then describe two artifacts rather than one. The focused targets are listed in the
-`Makefile`.
-
-## Layers and primary ownership
-
-Seven layers, each answering a different question about the same candidate:
-
-| Layer          | What it exercises                                                   |
-| -------------- | ------------------------------------------------------------------- |
-| `generator`    | Pure request-to-file behavior of the generator sources.             |
-| `types`        | Public-only strict compilation on the floor and current TypeScript. |
-| `candidate`    | The same generator scenarios executed through the real WASM.        |
-| `verification` | Contracts over manifests, publication, scripts, and workflow text.  |
-| `miniflare`    | Isolated D1 with fresh storage per test.                            |
-| `example`      | The canonical Worker in `examples/d1-worker/`.                      |
-| `managed-d1`   | Real D1 seams that only a live account can show.                    |
-
-`verification/coverage-manifest.json` assigns every promised behavior exactly one **primary owner** and any
-number of smoke tests; smoke tests are additional, never substitutes. Adding a behavior is three edits in one
-change: register the id literally in the test title, add the entry to `test/catalog.ts`, add the same entry to
-`verification/coverage-manifest.json`. A behavior that arrives in a new root test file adds two more: the file
-joins `ROOT_TESTS` and its bundle joins `ROOT_DIST` in the `Makefile`, and the file joins `include` in
-`test/tsconfig.json`. A coverage failure names the missing or duplicated owner — read it as "this behavior has
-no owner", not as a schema complaint.
-
-## Checked-in generated output and drift
-
-`test/miniflare/src/` and `examples/d1-worker/src/` hold Plugin output. The hand-written
-`test/miniflare/src/index.ts` and `examples/d1-worker/src/index.ts` are the only exceptions, and
-`scripts/check-generated-drift.mjs` preserves them during regeneration. `.prettierignore`
-lists the emitted files in those trees because `make test-generated-drift` compares them byte for byte; when
-their content should change, regenerate them from the candidate.
-
-`--mode mirror` regenerates into a temporary copy and leaves the worktree untouched. `--mode worktree`
-regenerates in a detached `git worktree` at `HEAD` and asserts `git status --porcelain` is empty. Both write
-the retained candidate to a `0400` temporary file and clean up unconditionally. Both need `sqlc` on `PATH`.
-
-## Regenerating the fixtures
-
-`scripts/generate-candidate.mjs` rewrites a copy of a fixture's sqlc configuration to point at the retained
-candidate `file:` URL and its digest, runs `sqlc generate`, and removes both temporaries. This block is the
-single source of the procedure:
-
-```
-make build
-SHA=$(shasum -a 256 build/plugin.wasm | awk '{print $1}')
-for dir in test/miniflare examples/d1-worker; do
-  node scripts/generate-candidate.mjs --candidate "$PWD/build/plugin.wasm" --sha256 "$SHA" --config sqlc.yaml --cwd "$PWD/$dir"
-done
-```
-
-## Sub-project formatting
-
-`examples/d1-worker/` and `test/miniflare/` are bun sub-projects that keep their own Prettier configuration;
-Prettier resolves configuration per file, so their hand-written sources stay tab-indented. Use bun inside those
-directories.
-
-## Compatibility configuration is authoritative
-
-`verification/compatibility.json` is the only home for the sqlc samples and their rationale, the known
-exceptions, the TypeScript floor and current versions, the exact Cloudflare baseline, and the exact tool
-versions. `scripts/compatibility-config.mjs` reads it, `scripts/workflows/emit-compatibility-outputs.mjs` feeds
-workflows from it, and `docs/compatibility.md` presents it to consumers. Change the JSON; every other copy is
-derived.
-
-**Decided, against the obvious default:** sqlc is sampled strategically — the floor, the tested ceiling, and
-the intervening releases tied to a material protocol or metadata change. A matrix over every sqlc minor was
-considered and rejected ([#13](https://github.com/mkuznets/sqlc-d1-typescript/issues/13),
-[#38](https://github.com/mkuznets/sqlc-d1-typescript/issues/38)).
-
-## Managed D1 creates real resources
-
-Managed-D1 runs provision live Cloudflare resources under the reserved name grammar
-`sqlc-d1-ci-yyyymmddthhmmssz-<run-id>-<attempt>-<8-lower-hex>` (`RESOURCE_NAME_PATTERN` in
-`scripts/managed-d1-contract.mjs`). Exact resource identifiers are persisted the moment they exist, primary
-cleanup runs unconditionally and reports separately from the test outcome, and **a cleanup failure is a failed
-release gate even when emergency recovery succeeds**. The weekly reaper (`make reap-managed-d1`) deletes only
-complete reserved names strictly older than 24 hours. Stateful scenarios run once; diagnose a failure rather
-than retrying it.
-
-Scenario ids are compiled in as `MANAGED_SCENARIO_IDS` in `scripts/managed-d1-contract.mjs`. The deployed
-endpoint accepts those ids and returns scenario outcomes; SQL, bind values, and expected rows stay out of the
-protocol in both directions. Operations, the protected Environment, token scopes, and the audit checklist live
-in `docs/managed-d1-verification.md`.
-
-## Publication is a verification layer too
-
-The `verification` layer also owns the publication contracts: object keys and their permanent HTTP metadata,
-the release body, the closed publication record, and the order in which surfaces may be written. Those rules
-live in `scripts/publication-contract.mjs`; ordering and the version-key boundary live in
-`scripts/publish-release.mjs`. Both are exercised without credentials and without touching the network — every
-seam is an injected `fetchImpl` whose double throws on any request it was not primed for. Operations and the
-audit checklist are in `docs/release-publication.md`.
-
-## Sensitive data stays inside the run
-
-`verification/evidence.schema.json`, `verification/managed-d1-evidence.schema.json`, and
-`verification/publication-record.schema.json` are closed schemas (`additionalProperties: false`); keep them
-closed, and add a field by naming it in the schema.
-
-Evidence, logs, artifacts, and issues carry candidate identity, configuration, scenario outcomes, exact
-resource identifiers, and cleanup facts. SQL text, bind values, result rows, session bookmarks, authorization
-headers, tokens, Cloudflare credentials, stack traces, error causes, and response bodies stay in the run that
-produced them. Secret identifiers and minimum permission scopes are documentable; their values live only in
-the Environment.
-
-## Running the gate
-
-`make verify-local` runs the full local gate from a clean build. `make verify-candidate` runs it against bytes
-someone else built, given `CANDIDATE_WASM` and `CANDIDATE_SHA256`. The focused targets each gate names are in
-the `Makefile`.
-
-## Decisions governing this area
-
-Read the issue rather than re-deriving the decision:
-[#13](https://github.com/mkuznets/sqlc-d1-typescript/issues/13) (verification strategy and disposable D1

 Publication turns one proven publication candidate into a published artifact. It runs only after every release gate has passed for that exact candidate, it writes the immutable R2 version key before it advertises anything, and it publishes the GitHub Release last.
 
-Everything below is executed by `.github/workflows/release.yml`. Nothing here is a manual procedure except the one-time configuration and the audit.
+Everything below is executed by the `publish` job in `.github/workflows/release.yml`. Nothing here is a manual procedure except the one-time configuration and the audit.
 
 ## What publication does, in order
 
-1. **Preflight** — read-only proof that the `sqlc` bucket is reachable, the R2 credential is scoped to that bucket alone, and the public custom domain answers for a known-absent key. It runs as its own job off the release identity, so a misconfigured account fails within a minute rather than after the full gate. Two checks report `not-verifiable` rather than passing: the immutable-releases setting and the Environment ref policy both need the Administration permission, which no job-scoped `GITHUB_TOKEN` can hold, so the manual audit below is what proves them.
-2. **Draft release** — create or reuse a draft whose body is byte-identical to the body this run would publish, and attach the retained WASM and its release manifest.
-3. **Draft verification** — download both assets again through the API and hash them.
-4. **Version key** — `aws s3api put-object` with `--if-none-match '*'` and `--content-md5`. A `412` is accepted only after a full-byte comparison proves the existing object is this candidate.
-5. **Direct verification** — `GetObject` from the S3 endpoint, hash the complete body, and assert `Content-Type`, `Content-Disposition`, `Cache-Control`, and the SHA-256 object metadata.
-6. **Public verification** — fetch the public URL unauthenticated, exactly as a consumer does, and hash the body. A `404` is propagation and is polled; a `200` with different bytes is an immediate hard failure.
-7. **Digest agreement** — one SHA-256 must equal the retained candidate, the release asset, the object metadata, the direct download, the public download, the manifest, and the digest quoted in the release body.
-8. **Publish** — `draft: false`. This is the moment the version becomes publicly advertised, and it is the last write of the run.
-9. **Record** — a closed JSON publication record is written as run evidence and uploaded as `release-publication-<run>-<attempt>`.
+1. **Revalidate** — the retained candidate bundle and the release manifest are validated once more against the release intent and the managed-D1 evidence, before anything is written.
+2. **Version key** — `aws s3api put-object` with `--if-none-match '*'` and `--content-md5`. The conditional write is what makes a version key immutable: if the key already holds bytes, R2 answers `412` and the step fails rather than replacing what is already advertised.
+3. **Public verification** — the public URL is fetched unauthenticated, exactly as a consumer does, and its SHA-256 compared to the candidate. The release notes may only advertise a URL that already serves the right bytes.
+4. **Publish** — `gh release create` attaches the WASM and its manifest and publishes the release. This is the moment the version becomes publicly advertised, and it is the last write of the run.
 
-No API response, ETag, `Content-MD5` acknowledgement, or `HEAD` result ever satisfies verification on its own.
+There is no dry-run mode. To rehearse a release, cut the next patch version — at pre-1.0 that is cheap, and it avoids a whole rehearsal-and-teardown apparatus that can only ever exercise a path the real release does not take.

 4. Confirm Actions artifact retention supports at least 30 days.
-5. Run the dry run below and confirm it leaves nothing behind.
-
-## Controlled dry run
-
-A dry run exercises the real GitHub and R2 accounts without creating a tag, without consuming a version key, and without publishing anything. It writes to a `rehearsal/<run-id>/` object key and a draft named `dry-run-v<version>-<run-id>`, a name that can never become a real tag, then deletes both.
-
-```sh
-gh workflow run release.yml --ref main -f version=0.0.0-dryrun1
-```
-
-Then:
-
-1. Rerun with the same `version`; the new run id produces a fresh rehearsal key.
-2. Rerun the publish job of the **first** run. It writes the same rehearsal key again from the retained candidate and reports `"outcome": "created"`, because teardown removed the previous attempt's object and draft before the run ended. What this proves is repeatability from retained bytes; it is not the conflict path. Neither the create-only conflict nor the draft-reuse path can be rehearsed at all — a dry run never leaves a surface behind for the next attempt to collide with — and `verification/publication-conflict` and `verification/publication-retry` own them instead.
-3. Download `release-publication-<run>-<attempt>` and validate it, once per attempt:
-
-   ```sh
-   make validate-publication-record RECORD=publication-record.json
-   ```
-
-4. Confirm the record shows `"mode": "dry-run"`, `"published": false`, and a `teardown` in which both surfaces are `deleted`.
-5. Confirm in Cloudflare that no `rehearsal/` object remains and that `plugins/` is untouched, and on GitHub that no release and no tag exist.
-
-To check the account configuration by hand, with the credentials exported in the shell:
-
-```sh
-make publication-preflight REPOSITORY=mkuznets/sqlc-d1-typescript VERSION=0.0.0-audit
-```
-
-Preflight reads only; it writes nothing to GitHub or R2.
 
 ## Recovery playbook
 
-The version key is the boundary. Before it exists the version is free; after it exists the version is permanently bound to those bytes, because the public URL is served with `Cache-Control: immutable` and may already be cached anywhere.
+The version key is the boundary. Before it exists the version is free; after it exists the version is permanently bound to those bytes, because the public URL may already be cached anywhere.
 
 | Situation                                  | What to do                                                                                                                                             |
 | ------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
 | Failure before the R2 key exists           | Nothing permanent happened. Delete the tag, fix the cause, and recreate the tag at the same version.                                                   |
-| Failure after the key exists               | Rerun the same workflow run so it resumes with the retained candidate. Only those bytes may ever occupy that key; changed bytes require a new version. |
-| Retained candidate lost before publication | Abandon the version. The candidate job refuses to rebuild on a rerun, and a rebuilt artifact is a different artifact.                                  |
-| Existing key with identical bytes          | Idempotent retry. Publication continues.                                                                                                               |
-| Existing key with different bytes          | Publication halts without writing. This is an immutable-key conflict; investigate before doing anything else.                                          |
-| Draft asset differs from the candidate     | Publication halts before touching R2. Inspect the draft by hand; a draft may be deleted manually only while no version key exists.                     |
-| Public download fails                      | The release stays a draft. Retry with the same bytes.                                                                                                  |
+| Failure after the key exists               | The bytes at that key are final. Rerun the workflow only if the retained candidate is still available; otherwise cut the next version.                 |
+| Retained candidate lost before publication | Abandon the version. A rebuilt artifact is a different artifact.                                                                                       |
+| Existing key with different bytes          | The conditional write halts with a `412` before anything is replaced. Investigate before doing anything else.                                          |
+| Public download fails or differs           | The release is not cut. Investigate the custom domain before retrying.                                                                                 |
 | After publication                          | Never replace or delete the tag, the release, the assets, or the object. Add a superseded notice to the release notes and publish a corrected version. |
 
-Every failure emits one `::error::` annotation naming the phase, plus the recovery sentence that applies to the side of the boundary the run reached.
-
 ## Release notes
 
-The maintainer writes the changelog in the annotated tag message; nothing generates it. The publish job reads `%(contents:body)` from the tag and renders it as the `## Changelog` section of the release body. A tag with no message body renders a commit-history link instead.
-
-The rest of the body is derived from the release manifest and is deterministic: the same manifest and tag message always produce the same Markdown, which is why a retry can byte-compare an existing draft instead of rewriting it. The body may quote no SHA-256 other than the artifact's and the manifest's.
+The maintainer writes the changelog in the annotated tag message; nothing generates it. `scripts/workflows/read-tag-notes.sh` reads `%(contents:body)` from the tag and the publish job passes it to `gh release create --notes-file`. A tag with no message body renders a commit-history link instead.
 
 ## Manual audit checklist
 
-1. Confirm the Environment ref rules, the absence of a reviewer, and the secret identifiers above.
+1. Confirm the Environment tag rule, the absence of a reviewer, and the secret identifiers above.
 2. Confirm the R2 token grants Object Read & Write on `sqlc` only, and that it is account-owned.
-3. Confirm `gh api repos/mkuznets/sqlc-d1-typescript/immutable-releases` reports `enabled: true`. This is the only proof there is: the same call from inside a workflow answers `403`, and preflight records it as `not-verifiable`.
+3. Confirm `gh api repos/mkuznets/sqlc-d1-typescript/immutable-releases` reports `enabled: true`. The same call from inside a workflow answers `403`, so this is the only proof there is.
 4. Confirm repository artifact retention supports 30 days.
-5. Run a dry run; download its record and validate it with `make validate-publication-record`.
-6. Confirm the record's `order` ends with the publish phase, and that on a dry run there is no publish phase at all.
-7. Confirm no `rehearsal/` object and no dry-run draft release survive.
-8. Inspect logs, the record, and the preflight artifact for credentials, tokens, signatures, authorization headers, and response bodies. The record schema rejects those fields structurally; the audit confirms the logs agree.
-9. Confirm the published release body quotes exactly the artifact digest and the manifest digest and no other.
+5. After a release, confirm the published release body quotes exactly the artifact digest and no other, and that the public URL serves the same SHA-256 the manifest records.
