Phase 9 Commit B from the agreed plan. With Commit A capturing what
AtoCore fed to the LLM and what came back, this commit closes the
weakest part of the loop: when a memory is actually referenced in a
response, its confidence should drift up, and stale memories that
nobody ever mentions should stay where they are.
This is reinforcement only — nothing is promoted into trusted state
and no candidates are created. Extraction is Commit C.
Schema (additive migration):
- memories.last_referenced_at DATETIME (null by default)
- memories.reference_count INTEGER DEFAULT 0
- idx_memories_last_referenced on last_referenced_at
- memories.status now accepts the new "candidate" value so Commit C
has the status slot to land on. Existing active/superseded/invalid
rows are untouched.
New module: src/atocore/memory/reinforcement.py
- reinforce_from_interaction(interaction): scans the interaction's
response + response_summary for echoes of active memories and
bumps confidence / reference_count for each match
- matching is intentionally simple and explainable:
* normalize both sides (lowercase, collapse whitespace)
* require >= 12 chars of memory content to match
* compare the leading 80-char window of each memory
- the candidate pool is project-scoped memories for the interaction's
project + global identity + preference memories, deduplicated
- candidates and invalidated memories are NEVER reinforced; only
active memories move
Memory service changes:
- MEMORY_STATUSES = ["candidate", "active", "superseded", "invalid"]
- create_memory(status="candidate"|"active"|...) with per-status
duplicate scoping so a candidate and an active with identical text
can legitimately coexist during review
- get_memories(status=...) explicit override of the legacy active_only
flag; callers can now list the review queue cleanly
- update_memory accepts any valid status including "candidate"
- reinforce_memory(id, delta): low-level primitive that bumps
confidence (capped at 1.0), increments reference_count, and sets
last_referenced_at. Only active memories; returns (applied, old, new)
- promote_memory / reject_candidate_memory helpers prepping Commit C
Interactions service:
- record_interaction(reinforce=True) runs reinforce_from_interaction
automatically when the interaction has response content. reinforcement
errors are logged but never raised back to the caller so capture
itself is never blocked by a flaky downstream.
- circular import between interactions service and memory.reinforcement
avoided by lazy import inside the function
API:
- POST /interactions now accepts a reinforce bool field (default true)
- POST /interactions/{id}/reinforce runs reinforcement on an existing
captured interaction — useful for backfilling or for retrying after
a transient error in the automatic pass
- response lists which memory ids were reinforced with
old / new confidence for audit
Tests (17 new, all green):
- reinforce_memory bumps, caps at 1.0, accumulates reference_count
- reinforce_memory rejects candidates and missing ids
- reinforce_memory rejects negative delta
- reinforce_from_interaction matches active memory
- reinforce_from_interaction ignores candidates and inactive
- reinforce_from_interaction requires minimum content length
- reinforce_from_interaction handles empty response cleanly
- reinforce_from_interaction normalizes casing and whitespace
- reinforce_from_interaction deduplicates across memory buckets
- record_interaction auto-reinforces by default
- record_interaction reinforce=False skips the pass
- record_interaction handles empty response
- POST /interactions/{id}/reinforce runs against stored interaction
- POST /interactions/{id}/reinforce returns 404 for missing id
- POST /interactions accepts reinforce=false
Full suite: 135 passing (was 118).
Trust model unchanged:
- reinforcement only moves confidence within the existing active set
- the candidate lifecycle is declared but only Commit C will actually
create candidate memories
- trusted project state is never touched by reinforcement
Next: Commit C adds the rule-based extractor that produces candidate
memories from captured interactions plus the promote/reject review
queue endpoints.
Phase 9 Commit A from the agreed plan: turn AtoCore from a stateless
context enhancer into a system that records what it actually fed to an
LLM and what came back. This is the audit trail Reflection (Commit B)
and Extraction (Commit C) will be layered on top of.
The interactions table existed in the schema since the original PoC
but nothing wrote to it. This change makes it real:
Schema migration (additive only):
- response full LLM response (caller decides how much)
- memories_used JSON list of memory ids in the context pack
- chunks_used JSON list of chunk ids in the context pack
- client identifier of the calling system
(openclaw, claude-code, manual, ...)
- session_id groups multi-turn conversations
- project project name (mirrors the memory module pattern,
no FK so capture stays cheap)
- indexes on session_id, project, created_at
The created_at column is now written explicitly with a SQLite-compatible
'YYYY-MM-DD HH:MM:SS' format so the same string lives in the DB and the
returned dataclass. Without this the `since` filter on list_interactions
would silently fail because CURRENT_TIMESTAMP and isoformat use different
shapes that do not compare cleanly as strings.
New module src/atocore/interactions/:
- Interaction dataclass
- record_interaction() persists one round-trip (prompt required;
everything else optional). Refuses empty prompts.
- list_interactions() filters by project / session_id / client / since,
newest-first, hard-capped at 500
- get_interaction() fetch by id, full response + context pack
API endpoints:
- POST /interactions capture one interaction
- GET /interactions list with summaries (no full response)
- GET /interactions/{id} full record incl. response + pack
Trust model:
- Capture is read-only with respect to memories, project state, and
source chunks. Nothing here promotes anything into trusted state.
- The audit trail becomes the dataset Commit B (reinforcement) and
Commit C (extraction + review queue) will operate on.
Tests (13 new, all green):
- service: persist + roundtrip every field
- service: minimum-fields path (prompt only)
- service: empty / whitespace prompt rejected
- service: get by id returns None for missing
- service: filter by project, session, client
- service: ordering newest-first with limit
- service: since filter inclusive on cutoff (the bug the timestamp
fix above caught)
- service: limit=0 returns empty
- API: POST records and round-trips through GET /interactions/{id}
- API: empty prompt returns 400
- API: missing id returns 404
- API: list filter returns summaries (not full response bodies)
Full suite: 118 passing (was 105).
master-plan-status.md updated to move Phase 9 from "not started" to
"started" with the explicit note that Commit A is in and Commits B/C
remain.
