Vault knowledge now reaches the agent at the moment it matters: an opt-in hook injects a bounded, fenced recall brief on every prompt (hard caps, confidence floor, one audit line per decision, nothing injected on any error), the morning brief renders a typed age-labeled activity timeline, and recurring recall gaps stop evaporating - they become durable task notes, surface as a session-start agenda, and close themselves once the gap is filled.

MCP agents gain the full write lifecycle - `brain_update_note`, `brain_append_note`, and the all-or-nothing `brain_write_batch` - and `o2b doctor --readiness` answers the Day-0 wiring question with three functional probes and a real exit code.

The hook process itself stays fail-open for the session. +- Trust gate (t_5f61130a): deterministic quarantine classification from structural and provenance signals already in the codebase (untrusted-source provenance, contamination entity signals, self-approval guardrail state); zero-ranked items keep zero prompt influence but are counted with reasons in the receipts; receipts are compact references consistent with the existing context-receipt model, never repeated payloads. +- Supersede fade (t_c4a9cef8): inbound supersedes or superseded_by relation on an unchanged note applies a fade multiplier through kernel 1 on both search paths; the existing superseded-non-tip tombstone drop is untouched; fade factor is a named constant beside the freshness multipliers. +- Update and append tools (t_3ff3fe77): target must exist (typed error otherwise); same safety envelope as create (path traversal, Brain machinery root, vault-scope exclusions); frontmatter patch merges keys, body update replaces, append appends; all through kernel 2 so a mid-write failure rolls back. +- Batch tool (t_7718ab22): whole batch validated and projected in memory before any disk write; first invalid operation aborts the batch with a typed error naming the operation index; fail-closed, no partial application. +- Timeline (t_4adb0b8b): presentation only over existing brief data; type marker derives from the existing eventType and item kind, age label from stored timestamps; a fixed structural marker vocabulary (config-free), no natural-language classification. +- Gap loop (t_67d38036): recurrence detection over existing gap_counts telemetry with a tunable threshold; promotion creates a durable vault task file at session end; agenda renders open gap tasks at session start through the same rendering helper; auto-close mirrors the dream freshness auto-resolve precedent; opt-in via env flag. +- Clip protection (t_5be0654d): agent_id joins session_id on pack and continuity identity; the clip routine preserves both under any output budget; regression test with a tiny budget. +- Doctor readiness (t_cc234ff5): new probes are additive checks with per-check timeout and a non-zero exit code contract behind an explicit flag so existing doctor output stays byte-identical without it; probes report pass, fail with reason, or skipped-not-configured, never a silent pass. +- Rider de-flake: the test derives the expected log day from the returned loggedAt, removing the wall-clock dependence. + +## File changes + +- New: src/core/search/rank-adjust.ts (kernel 1), src/core/brain/write-batch.ts (kernel 2), src/core/brain/trust/retrieval-gate.ts, src/core/brain/receipts (trust assessment and decision trace builders), src/core/brain/render/activity-line.ts (shared rendering helper), src/core/brain/gaps/gap-loop.ts, hooks/recall-inject.ts (or hooks/lib extension per existing hook layout), src/mcp/brain note update, append, and batch tool registrations, doctor readiness probe module. +- Modified: src/core/search/ranker.ts and result-filters.ts (mount kernel 1 on both paths), src/core/brain/session-recall.ts and src/mcp/brain/recall-tools.ts (include_raw plus discriminator), src/core/brain/token-impact.ts (protected fields), src/core/brain/morning-brief.ts (timeline render), src/core/doctor.ts and the doctor CLI verb (probes, exit code), hooks/hooks.json (UserPromptSubmit registration), src/mcp/brain/notes-tools.ts and context-tools.ts (ride kernel 2), tests beside every change, tests/core/brain/lifecycle/temporal-replace.test.ts (rider). +- Exact paths follow the codebase layout discovered during TDD; implementers adapt names to neighboring conventions and record deviations in the commit body. + +## Risks and open questions + +- Kernel 1 touches the hottest ranking path; mitigated by byte-identical behavior when no adjuster is registered and by regression tests on both paths. +- The operation vocabulary of kernel 2 must not leak MCP shapes into the core; the core takes typed operations, the MCP layer maps params. +- UserPromptSubmit hook latency budget: the recall path must stay within a small fixed time budget; on timeout it abstains and logs. +- Gap-loop task files must not trigger unrelated agents; they live under the vault Brain area as plain durable notes, not on the Hermes board. +- Registry guards cap tool description lengths; new tool descriptions are written to the 300 and 160 character limits from the start. diff --git a/docs/brainstorm/recall-trust-and-write-surface/plan.md b/docs/brainstorm/recall-trust-and-write-surface/plan.md new file mode 100644 index 00000000..971da5f9 --- /dev/null +++ b/docs/brainstorm/recall-trust-and-write-surface/plan.md @@ -0,0 +1,75 @@ +# Trusted recall and memory write surface - implementation plan + +Sequence follows consultant Variant 3.

Seams 3 and 4 are deliberately NOT abstracted: the recall hook, timeline, and gap agenda each stay at their own existing hook/brief anchor sharing only a rendering helper, and clip-protected identity is a small protected-field contract in `token-impact.ts` that `include_raw` simply respects.
