Merge remote-tracking branch 'origin/master' into worktree-plugin-config-guideline

Master's docs-overhaul stack (#142-#144) rewrote AGENTS.md into the
slim budget-gated form and repointed the review skill's citations.
Resolutions:
- AGENTS.md: master's rewrite wins; the no-hardcoded-tunables
  convention is re-added as one terse bullet in the new style, after
  'Explicit > implicit at package seams'. Within the verify-doc-budgets
  ceiling, so no displacement or raise needed.
- dsh-code-review SKILL.md: master's repointed citations win; the
  hardcoded-tunables reviewer check and the Conventions keyword are
  re-applied on top.
- packages/README.md: master replaced the hand-maintained dependency
  list (which carried this branch's chars-per-token wording) with a
  pointer to the generated module graph — master's side taken whole;
  the estimator wording lives on in the compact package READMEs.

 1. **Docs in sync.** If the PR changes a config key, default, error code, wire field, or event name, it must update the package README + module/JSDoc in the same diff. The `doc-sync` gate (check #4) does not catch prose drift in config keys, defaults, error codes, or wire fields — that is on the reviewer, but it is still required, not optional.
 2. **Core-data-structures catalog in sync.** If the PR adds, removes, or reshapes a type the [core-data-structures catalog](../../../docs/core-data-structures/core.md) documents — a new `…Map` variant, a new content-block/session-event type, a field on `GenerateOptions`/`Agent`/`ToolDefinition`/a bash type, or a whole new core/seam type — it must update that catalog in the same diff (prose + any verbatim ` ```ts type-equiv ` block + the 1:1 `scripts/type-equiv.manifest.json`). The `verify-type-equiv` gate (part of `doc-sync`) catches a *drifted paste* of an already-documented type, but it cannot tell you a brand-new core type went undocumented — that judgment is yours. Confirm a genuinely spine-level type landed in core.md and a new capability's vocabulary on a sub-page, per the spine-vs-seam line in [core.md § What counts as "core"](../../../docs/core-data-structures/core.md#what-counts-as-core). A pure internal type with no cross-package reach needs no catalog entry — say so if it's a judgment call.

 ## Reviewer-only checks (gates can't catch these — judgment required)
 
 Where your independent reasoning earns its keep. Start here, then keep going across the broader aspects above.
 
-- **e2e verifies the world, not the agent's self-report.** For real-API tests, confirm the assertion re-runs the command/checks the file externally — a keyword probe lets a cheating agent pass (see AGENTS.md e2e bullet). For a behavior change to the agent's real flows, a no-key/mock test alone is usually insufficient: a with-key e2e (especially a smoke test that boots the real example and checks the world) is cheap here and catches "green units, broken product" — encourage it rather than treating real-API tests as expensive (see AGENTS.md § Secrets / .env).

 - **Plugin export shape + real-loader coverage.** A new/changed `cordis.yml`-loaded plugin: is it a function/namespace plugin (`name`/`inject`/`Config`/`apply` named exports) with NO `export default`? A stray default export makes the Loader's `unwrapExports` drop `inject` and the plugin crashes at load with `cannot get property … without inject` — invisible to hand-built `ctx.plugin({...})` tests and to line coverage. Confirm there's a test driving it through the REAL loader path (the no-key subprocess e2e for ACP is the model). And any opportunistic read of a service NOT in `static inject` should use `ctx.get(name)`, not `ctx.<name>` (the property proxy throws through a foreign shadow). See [packages/AGENTS.md](../../../packages/AGENTS.md) and [docs/postmortem/0001](../../../docs/postmortem/0001-acp-default-export-drops-inject.md).
 - **Seam discipline.** New swappable capability? Check it's split per the capability-seams RFC (interface / impl / consumer), and that the consumer injects the interface key, never an implementation type.
 - **Hardcoded tunables that should be plugin config.** A literal timeout, grace period, output/truncation cap, result-count limit, retry count, buffer size, model name, API base URL, user agent, or filesystem path introduced inside a plugin belongs on the plugin's schemastery `Config` with the shipped value as its default (AGENTS.md § Conventions "No hardcoded tunables in plugins"). A named `DEFAULT_*` constant or a test-only injection seam is not configurability — the question to ask is whether a `cordis.yml` deployment can change the value without a code edit. Protocol/wire constants, semantic constants, values pinned by an external spec, and security invariants are exempt; a new `Config` field also needs its README row and range validation. No gate detects a hardcoded tunable — this check is entirely on the reviewer.
-- **Test quality — sufficiency, not just coverage.** 100% per-file coverage and a green suite are necessary, not sufficient: they prove the lines *ran*, not that the feature *works the way it ships*. Judge whether the tests are sufficient on two axes. (1) **Would they fail if the behavior regressed?** A test that passes but asserts the wrong thing — or restates the implementation instead of the contract (events fired, disposal reached, the world changed) — is worse than none. (2) **Do they exercise the REAL thing, the way it's actually used?** Prefer the genuine collaborator over a fake, drive the change through its real entry path (the cordis Loader, the ACP bridge, a booted subprocess — not a hand-built `ctx.plugin({...})` that bypasses `unwrapExports`), and verify the WORLD (re-read the file/log/registry externally), not the agent's self-report. A test that fakes the inputs just enough to cover every line will agree with whatever the author assumed; the real thing won't. When a test sets up a *clean/happy* path to reach a line, ask whether the line's PURPOSE is exercised — e.g. a durability/teardown path "tested" by a fully-completed turn never proves the mid-flight teardown it exists for; a torn-tail recovery branch covered by a well-formed log never proves recovery. Flag tests that hit the line but not the scenario. See AGENTS.md § Defensive patterns "Line coverage is not behavior coverage" and "Prefer the REAL implementation over a mock/stand-in in tests".

 - **Snapshot coverage for transcript/UX changes.** If the PR changes the editor-facing transcript or end-to-end agent UX — the ACP bridge's event→update translation, the agent loop's observable output, tool presentation, or anything an editor renders — it must add or update a snapshot scenario (`examples/*/tests/**/*.snapshot.ts`, goldens under `examples/acp-agent/tests/snapshots/`) or note explicitly why none applies (AGENTS.md § Conventions). Review the golden diff itself: a changed `stdout.golden.txt` / `session.golden.txt` is a behavior change in disguise — confirm it's intended, not an accidental regression someone re-recorded away. A pure internal refactor with no observable-output change is exempt, but the PR should say so. See [docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md](../../../docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md).
 - **Bilingual docs: review translation quality, not just pairing.** If the PR adds or edits a doc pair, read the changed English and Chinese sides and compare the meaning, not only the mechanical diff. Verify terms against [terminology.md](../../../docs/i18n/terminology.md), including first-occurrence annotations and "do not translate as" prohibitions; if a new term has no established precedent, the PR should keep it in English, list it under `待定术语`, and update the terminology table once the rendering is decided. A green `verify-translation-pairing` only proves hashes, switchers, and structure were recorded — it does not prove the translation is faithful, natural, or correctly termed. Treat [translation-rules.md](../../../docs/i18n/translation-rules.md) MUST/MUST NOT violations as blocking.
-- **Intent and contracts.** Does the change do what the PR says, and honor the documented contract on *both* sides of every seam it touches (see AGENTS.md "Honor cross-seam contracts on BOTH sides")?
