- Correct the SessionStore signature: `get(id: string)` is non-optional,
not `get(id?: string)` (only create/prepare take an optional id).
- Broaden the ACP brand-erosion description and the acceptance criterion
beyond `Map<string>`: the session-id surface also includes the
`bySession` WeakMap, the `loadingIds` Set, and the exported
`streamSessionEventUpdate(sessionId)` signature.
- Use bare inline code spans for code paths instead of markdown links,
matching the house style of the other architecture RFCs and removing the
link/bare-span inconsistency within this file (doc-to-doc cross-links
stay markdown links per docs/AGENTS.md).
Extend the existing Branded<B> machinery (CallId/SessionId/AgentId) to the
unbranded cross-boundary IDs that meet the brand.ts policy bar — chiefly the
model-facing bash task id (BashTask.id, the `bash-N` counter that shares
SessionId's `name-N` shape) and a distinct OwnerToken brand for the bash
owner token — and fix the brand erosion where existing brands decay back to
`string` at Map keys and method params.
Scoped focused per the "not every string needs a brand" policy: ModelId,
ToolName, numeric ordinals, and validated construction are listed as
deferred extensions, not in-scope work. Filed under proposed/architecture.
Add a second axis to every RFC — its class (feature, bug-fix,
simplification, architecture, process, testing) — encoded in the path
as docs/rfc/{lifecycle}/{class}/file.md. The folder is the label, so
the closed set is enforced by structure rather than a parsed field.
Two new doc-sync gates back it:
- verify-rfc-classification: every RFC sits in a valid class folder and
the README index lists it under the matching lifecycle→class heading.
- verify-doc-refs: every docs/*.md path cited in a packages|examples TS
comment resolves — closes a drift class verify-md-links can't see, and
catches the four comment refs this reorg moved.
The README gains a Classification section explaining the taxonomy and
per-class index sub-sections. A self-referential process RFC records why
the scheme is path-encoded and gated.
