BigBrain v0.27.0

Added

• Added canonical components, products, and processes page collections,
  filing rules, and folder recommendations for infrastructure knowledge.
• Added focused graph network and timeline views with provenance-aware timeline
  updates.

Changed

• Added optional per-feed RSS guidance so each registered feed can define what
  to prioritize, what to ignore, and how its article events should be handled.
• Tightened the source-article relevance gate so low-value articles can be
  ignored before creating a raw artifact or Brain page.
• Preserved the RSS listener description as source identity while using the
  dedicated guidance field for ingestion scope, with legacy descriptions kept
  as a compatibility fallback.

Agent update actions

• Source installs: update to the v0.27.0 tag, run npm install, npm link,
  and npm run build:dashboard, then restart the BigBrain desktop, dashboard,
  and source-managed MCP services. Verify bigbrain sync --json,
  bigbrain health --json, MCP initialization, and npm test.
• Review registered RSS listeners and move any ingestion instructions that are
  currently in description into the new guidance field. Keep description
  for the feed's identity and purpose. Existing feeds remain compatible because
  RSS descriptions are used as a fallback when guidance is absent.
• No Brain page, timeline, or database migration is required. The new
  components, products, and processes collections are created by the
  normal Brain layout setup when needed.
• Active Codex skill copies remain machine-local. Refresh the packaged source
  article-ingestion skill from the release and restart event-ingestor services
  so the relevance gate and per-feed guidance are active.

Verification

• Full test suite passed.
• Dashboard production build passed.
• Standalone MCP bundle build passed, including its release manifest and
  checksum.
• Package dry-run and source version, lockfile, tag, and artifact metadata
  checks passed.
