Why: the approved collaboration plan U1 requires a fixed deployment manifest, tier config contract, migration mapping, capacity contract, isolation test scheme and KTD14 copy-protection contract as the single source of truth for team-tier operations.
Evidence: contract keys match backend config.go tier/pool fields (U2, backend branch feature/collab-storage-pg-tier); local verification used svc.sh collabtest on 127.0.0.1:8897 and Redis on 6399.
Impact: docs only (new guide + usage.md cross-links); no code change.
Refs: proposals/2026-10-11-collaboration-storage-and-distribution.md sections 5 (U1/U2), KTD1/KTD8/KTD12/KTD14.
Why: downstream parsers are unreachable through the Host handle and the base lacks xlsx/pptx parsers; MS1 needs both. The snapshot also missed interface methods, so adding one was undetectable.
Evidence: request follows compat-policy sect.6 four elements; behavior contract and limits in the proposal body (documents has no CI; verified via git diff --check recorded on the Dev task card).
Impact: docs only; compat-policy sect.3 gains one sentence, usage.md format list gains xlsx/pptx.

Why: T2-T4 changed the interaction foundation (pure-inbox rail, four-entrance command bus, overlay workspaces) and the guide still described the classic tabs; T5 acceptance also requires the verification record with the zero-page walkthrough.
Evidence: zero-page walkthrough 12/12 PASS on a fresh real binary (fresh data dir: empty instance -> project/conversation -> slash commands -> #upload card lifecycle -> card action receipts -> tidy -> HITL block+resolve -> button-entrance dispatch -> plugin workspace declaration -> artifacts -> four-entrance audit); StatusLamp shape+color dual encoding asserted by ui suite; combo make test at pinned heads.
Impact: usage guide sections 4.2-4.7/5/6.2/7 rewritten; new T5 record; no code change.
