Changes

• Bind chat drafts, attachments, submit/stop callbacks and late results to the current actor/application/view lifecycle.
• Correct generation dispatch boundaries, persistence-only recovery, tool/message association and SSE/moderation handling.
• Protect effective credential changes and unresolved quota with an additive database migration and shared locking.
• Preserve structured errors through the LangChain client/hook/product page and distinguish effective actions from backend support.
• Update public integration/governance documentation; no site-specific configuration or internal evidence is included.

Validation

• Dev Node 24.22.2 / pnpm 10.34.9: 229 suites, 2192 tests pass, including isolated PostgreSQL/HTTP/RLS regression.
• Root/API/shared types, changed-file formatting, 11 guards, and shared/API/Web production builds pass.
• Lint: zero errors; 11 pre-existing warnings, no new warnings compared with the baseline.
• Full public source hashes match the validated snapshot; source and commit-range publication scans pass.
• Existing containers and active build artifacts preserved. Stage validation of this candidate is pending and will follow develop integration.

Deployment

• Apply the additive 20261114170000_protect_pending_agent_credentials_and_quota.sql before updating the matching API/Web; do not rewrite old migrations.
• Stage migration, production-mode PM2 build, HTTPS automatic checks, representative dual-API checks and user manual acceptance remain separate gates.
• No production deployment, version tag or Release is included.
