Tianyi Cui 26339144e3 fix(docs): address Codex review round 2 — repoint every remaining moved-policy citation
The definitive sweep (audit every AGENTS.md mention in packages/, docs/,
examples/, scripts/) found thirteen more citations of relocated policy
and two citations of rules that never existed as quoted:

- with-key policy comments (web deepseek/perplexity e2e headers) ->
  docs/testing.md; real-impl-over-mock comments (acp harness, load,
  stream-update specs) -> docs/testing.md; defensive-pattern quotes
  (acp index.ts x3, stream-update) -> docs/defensive-patterns.md.
- md-tier repoints: real-api-e2e RFC, tool-schema-catalog RFC,
  postmortem 0001 guardrail row, adding-a-package cookbook,
  drop-bash-output-spill-files RFC, acp-subagent-backend RFC phrasing.
- Two false attributions dropped in favor of self-contained reasoning:
  tool-todo's 'don't validate scenarios that can't happen' and the
  bash-stdin-env RFC's 'Don't add features beyond what the task
  requires' (neither rule ever existed under those names).
- Citations of the two 'not golden truth' doctrines stay: those bullets
  survive verbatim in the root conventions.

Note: packages/support/ui-stdio readline TTY spec flakes under full
coverage on a heavily loaded box (passes standalone and passed the
same tree's coverage run minutes earlier); untouched by this stack.

# Cookbook: adding a workspace package
The file-by-file checklist for a new `@deepseek-ai/dsh-<name>` package. (Verified by the bash and adapter packages; if it drifts, fix it here.)
## 1. Create the package
```
packages/<group>/<pkg>/
package.json # copy from packages/core/tools, adjust name/description/deps
tsconfig.json # extends ../../../tsconfig.base.json, rootDir src,
# outDir lib/types, references: ../../../vendor/cosmokit,
# ../../../vendor/cordis (+ ../../../vendor/schemastery if
# you use Config, + ../../<group>/<dep> for each dsh dep)
src/index.ts # service default export or plugin (name/inject/apply/Config)
tests/<x>.spec.ts
README.md # service API, events, extension points, design notes
```
Choose an existing group when one matches the package's role (`core`, `llm`, `bash`, `compact`, `subagent`, `todo`, `session-persistence`, `ui`, `util`, or `support`). A new group is allowed, but it is a pure container: no `package.json`, no source files, and packages still sit exactly one level below it.
package.json invariants (enforced by `pnpm run constraints` / `scripts/check-workspace-constraints.ts`): `private: true`, `version: 0.0.1`, `type: module`, `main: "lib/index.js"`, `types: "lib/types/index.d.ts"`, `exports["."].types: "./lib/types/index.d.ts"`, `exports["."].default: "./lib/index.js"`, `cordis` in BOTH peerDependencies and devDependencies (same range). Mirror every dsh peer dependency in devDependencies. `schemastery` goes in `dependencies` (it is a runtime validator), matching agent-loop. The `files` list is precise: `lib/index.js`, `lib/types/**/*.d.ts`, `lib/types/**/*.d.ts.map`, and `src`; do not publish `lib/types` JS or JS-map intermediates or stale root declaration files. CLI app packages with a package `bin` include `lib/bin.js` immediately after `lib/index.js` in `files`.
In-package relative imports use explicit `.ts` specifiers in source (for example, `export * from './types.ts'`). The compiler rewrites those to `.js` in emitted JS and leaves explicit `.ts` specifiers in declarations, which standard NodeNext/Node16 TypeScript consumers resolve to the sibling `.d.ts` files.
## 2. Register it in the root configs
| File | Change |
|---|---|
| `tsconfig.base.json` | no edit for an existing group; for a new group, add a `./packages/<group>/*/src` candidate to the `@deepseek-ai/dsh-*` wildcard |
| `tsconfig.json` | add `{ "path": "./packages/<group>/<pkg>" }` to `references` |
| `tsconfig.build.json` | add `{ "path": "./packages/<group>/<pkg>" }` to `references` |
| `knip.json` | only if the package has non-`*.spec.ts` entries (e.g. `*.e2e.ts` → add a per-workspace override like `packages/llm/llm-deepseek`) |
Covered automatically by globs or package-manifest discovery — no edits needed: root `package.json` workspaces, `scripts/publint-all.ts`, `tsdown.config.ts`, `vitest.config.ts`, `eslint.config.mjs`, `scripts/check-workspace-constraints.ts`.
## 3. Decide the package topology
For a swappable capability, split interface / implementation / consumer into separate packages (see docs/architecture.md § "Capability seams" — the bash trio is the template). A single-purpose plugin stays one package.
## 4. Verify
```sh
pnpm install # registers the workspace
pnpm run constraints && pnpm run typecheck && pnpm run lint
pnpm run test:coverage # 100% per-file over src (types.ts exempt)
pnpm run build && pnpm run hygiene
```
Test expectations: every registry/registration needs an HMR-safety test (register from a child fiber, dispose it, assert cleanup). Excessive tests are welcome — see [docs/testing.md](../testing.md).
