brainless 0.4.0

• Concept pages. A summary says what one source said; a concept page says what the
  vault knows about one idea, and every new source updates it in place.
  • A disagreement keeps both positions with sources and dates.
  • An outdated claim is struck through, never deleted.
  • Every claim carries a confidence label.
  • tools/concepts.py validates each rewrite.
  • New concepts are proposed into _Agent-Context/concepts.md and wait for a yes.
  • The old articles phase is retired, and --only concept-migrate moves its pages over.
• A connected graph.
  • A deterministic linker ties summaries to the people, companies and concepts they
    mention. It holds back when a first name belongs to someone else.
  • INDEX.md gives one line per page, with topic indexes in .wiki/_index/.
  • Aliases in _Agent-Context/aliases.md catch the words people actually use.
  • Search folds Turkish letters.
  • A project mirror that shares a name with an entity becomes "(project)".
• Measured.
  • tools/wiki_metrics.py tracks the orphan rate, links per page, the main component and
    the bridge pages, week on week, in the scorecard and in HEALTH.md.
  • tools/retrieval_eval.py scores golden questions every night.
  • tools/wiki_dedupe.py proposes merges and never merges.
  • brainless graph writes a Gephi file coloured by page type.
• Checks, not requests.
  • Claude Code hooks (tools/hooks/claude_guard.py) ask before human-area writes and
    deletions, and refuse secrets and misplaced briefings.
  • tools/output_guard.py refuses model chatter and nested pages before they are
    written.
  • tools/run_log.py records every scheduled run with its counts, so a job that ran and
    did nothing shows up.
  • The nightly job no longer swallows a failed digest or the compiler's exit code.
• New doors.
  • brainless media turns YouTube and Apple Podcasts episode links into timestamped
    transcripts, queued and transcribed locally.
  • brainless chats brings Claude or ChatGPT history in, triaged and filtered first.
• Backups. brainless backup seals the vault and its history with age once a month,
  into a folder sync does not reach. verify is the restore test.
• Answer rule. Answers from the vault cite a page for every claim, keep outside
  knowledge under its own heading, and end with what was read and what is not covered.
