Skill System BH-CNS

BH central nervous system surface with scaffold status, component/plugin registry, consciousness bootstrap registry, common sense/terminology registry, shadow cron registry inventory, and project-local behavior registry plumbing.

• Single binary: bin/bh-cns
• Implemented now: status, cron list/register/verify
• Implemented now: memory status/search/store/metabolism-plan/cold-search/mcp-check
• Implemented now: component list/verify/status/enable/disable
• Implemented now: consciousness list/bootstrap/verify
• Implemented now: knowledge list/verify/lookup/add-common-sense/add-term
• Implemented now: behavior list/register/verify/diff
• Implemented now: fail-soft antigen recognition in behavior verify for inbox direct patch and behavior read-gate warnings
• Implemented now: neural contract substrate self-test (neural --self-test) over registry/neural/*
• Still stubbed: runtime immune, runtime neural actions (autopilot|sensory|sendkey)
• No cron install, no global hook install, no hard immune blocking, no neural runtime migration in this layer

Source contracts

• /datas/store162/arthur0824hao/Work/.tkt/meetings/2026-04-13-bh-cns-immune.md
• /datas/store162/arthur0824hao/Work/.tkt/artifacts/dispatch-bhcns-v1-draft.md
• /datas/store162/arthur0824hao/Work/.tkt/bundles/B-bhcns-01-scaffold/bundle.yaml

Current surface

• bh-cns status reports bundle metadata and registry paths.
• bh-cns component list/verify/status/enable/disable treats BH-CNS as a lightweight plugin substrate and checks or overrides pluggable organ health. skill-system-memory is the first registered organ; MCP is only an optional edge surface.
• bh-cns memory status/search/store/metabolism-plan/cold-search/mcp-check is the plugin-direct memory API. It sets SKILL_PGDATABASE=Work-memory, calls the registered memory organ entrypoint instead of depending on native MCP transport, and can inspect MCP config drift as an optional-edge lesion.
• bh-cns consciousness list/bootstrap/verify declares per-consciousness postcompact/session-start context injection: iron rules, persona/soul profile, nerve map, sensor map, memory hints, and inbox route.
• bh-cns knowledge list/verify/lookup/add-common-sense/add-term owns BH common sense and Arthur-approved terminology. "把這件事變成常識" maps to add-common-sense; accepted names map to add-term. Add commands update the registry and attempt Work-memory writeback unless --no-memory is passed.
• bh-cns cron list refreshes registry/cron/discovered.yaml from live crontab -l, .tkt/scripts/*.sh, and hook config surfaces without mutating them.
• bh-cns cron register writes manual shadow rows into registry/cron/state.yaml only.
• bh-cns cron verify checks W-3 required fields across manual plus discovered rows.
• bh-cns behavior register stores {file_path, file_hash, behavior_spec, registered_by, registered_at, last_verified} rows with a 7-day grace expiry.
• bh-cns behavior verify compares current hashes and reports infection-style findings when drift occurs.
• bh-cns behavior verify --operation-target <file> --behavior-read-age-hours <n> emits fail-soft warning bh-problem://behavior/missing-read-gate when no recent read/write evidence exists.
• bh-cns behavior verify --probe-inbox-file <.../.tkt/inbox/*/inbox.md> --writer <cmd> emits fail-soft warning bh-problem://inbox/direct-patch for non-approved writers.
• bh-cns behavior diff shows registered vs current hash for one file.
• bh-cns behavior verify --bypass-with-incident --incident-root <fixture> writes a 7-day TTL incident artifact only inside the explicit fixture root.
• bh-cns immune ... is a stub for B-bhcns-04/B-bhcns-05.
• bh-cns neural --self-test --json validates neural hierarchy contract registry/fixtures without mutating runtime pathways.
• bh-cns neural autopilot|sensory|sendkey remains stub for B-bhcns-06 runtime migration.

Cron registry rules

• W-2 private cron registration rule and W-4 emergency bypass notes live in registry/cron/README.md.
• registry/cron/registry.yaml remains the comment-level contract source.
• registry/cron/state.yaml and registry/cron/discovered.yaml are the mutable/runtime artifacts.

Behavior registry rules

• registry/behavior/registry.yaml remains the comment-level row contract source.
• registry/behavior/state.yaml stores active registrations.
• registry/behavior/read-gate.yaml stores read/write evidence used by fail-soft behavior-read gate checks.
• registry/behavior/README.md documents per-project scope, fixture-only bypass, and the 1-week grace rule.

Antigen envelope rules

• registry/antigen/envelope.schema.yaml defines stable antigen IDs and condition envelope fields.
• registry/antigen/state.yaml is append-only warning ledger for v02 recognition stage.
• v02 stays fail-soft: warnings and reports only, no hard block.
