Architecture & design:
- Arch A: introduce resolveProvenance() as the single source of truth for
deriving a write's actor/aiChatId from the SIGNED identity, and wire it into
BOTH transport seams — the REST jwt.strategy and the collab
authentication.extension. Previously the collab seam derived actor from the
token claim alone and ignored user.isAgent, so a flagged service account's
page-content edits over the websocket persisted as lastUpdatedSource='user',
drifting from REST. The seams now share one resolver and can't diverge.
- Arch B: drop AiAgentBadge's page-history coupling. The generic ui/ badge no
longer imports historyAtoms; it exposes an onActivate callback fired after the
deep-link, and the history row passes onActivate to close its own modal.
Suggestions/warnings:
- S1: soften the jwt.strategy provenance comment (applies to every REST write).
- S2/suggestion-3: drop the redundant comment-list-item null-aiChatId test
(covered by ai-agent-badge.test.tsx).
- S3: de-duplicate jwt.strategy.spec test #3 (the no-claim→'user' half
duplicated test #2); keep only the signed actor='agent' claim assertion.
- W2: add keyboard-activation tests for the badge (Enter/Space, unrelated key).
- W3: flip the design doc status to "реализовано (#143)".
Tests:
- new auth-provenance.decorator.spec.ts unit-tests resolveProvenance +
agentSourceFields.
- new collab-seam test: is_agent user with no claim → actor='agent'
(Arch A regression guard).

Document Variant B for showing MCP-created comments (and pages) as AI
rather than as the service-account user, reusing the existing agent
provenance infrastructure (§15 C3).
- Root cause: MCP logs in via a plain service-account token, so
provenance.actor stays 'user' and created_source defaults to 'user';
the comment sidebar also renders no AI badge.
- B1 (backend): mark the MCP identity as agent via a new users.is_agent
flag; jwt.strategy derives req.raw.actor from it (non-spoofable).
Relax the provenance aiChatId type to string | null for external MCP.
- B2 (frontend): extend IComment with createdSource/aiChatId, extract a
shared AiAgentBadge, render it in comment-list-item.
- Includes edge cases, tests, scope decisions, and acceptance criteria.
