Add a placement table to the Definition section: which `groupTree`
position a Chat Node declares for an opening human input, another Turn
input, a Turn notice outside folding, an independent folded row, and
ordinary process content, with links to the contract and the built-in
positions, and a pointer to `exclusive` claims.
State in the `exclusive` JSDoc and the Conversation reference that the
claimed target's fallback does not run and that a fallback's own claim
has no effect. Reword the `input` position as the Turn's opening input
and separate the finalized-answer exemption from position-less
`assistant-step` rows. Point both package READMEs at the claim and the
group-tree positions.
Add the exclusive Conversation matches Agent Note; bring the group-tree
note up to the `input` position and the migrated kind lists, and the
timed-question note up to claim-based reply deduplication. Pair the
Chinese Conversation reference and Chat grouping README with the
English updates.
Move `docs/defensive-patterns.md` into `docs/defensive-patterns/`, one page per
artifact plus a README router, and state each rule as its requirement, the
condition a reviewer judges it by, its boundary and approver, and a correct and
a wrong example.
- `general.md` (the moved page): the existing bug-class rules plus timing,
value representation, shared-state ownership, decentralization, performance
evidence, and migrations.
- `package-surface.md`, `remote-and-api.md`, `client-components.md`,
`conversation-and-session.md`: the review requirements for those artifacts,
linking type definitions and semantics to `docs/subsystems/` instead of
restating them.
- `README.md`: the habits behind the rules and the route from artifact to page.
- `dsh-code-review` reads the owning pages before judging a diff; the
`dsh-architecture-discipline` routing skill is retired in favour of the
directory, and every inbound reference is repaired.
- Chinese counterparts, pairing records, and the documentation tier table are
updated together.
