From 6ac7f61819b3d166fe0be73d23f96c1e3ae0998e Mon Sep 17 00:00:00 2001 From: root Date: Sat, 25 Apr 2026 19:31:44 -0500 Subject: [PATCH] pathway_memory: Mem0 versioning + deletion (upsert/revise/retire/history) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per J 2026-04-25: pathway_memory was append-only — every agent run added a new trace, bad/failed runs polluted the matrix forever, no notion of "this is the canonical evolved playbook." Ported playbook_memory's Phase 25/27 patterns into pathway_memory so the agent loop's matrix converges on best-known approaches per task class instead of bloating. Fields added to PathwayTrace (all #[serde(default)] for back-compat): - trace_uid: stable UUID per individual trace within a bucket - version: u32 default 1 - parent_trace_uid, superseded_at, superseded_by_trace_uid - retirement_reason (paired with existing retired:bool) Methods added to PathwayMemory: - upsert(trace) → PathwayUpsertOutcome {Added|Updated|Noop} Workflow-fingerprint dedup: ladder_attempts + final_verdict hash. Identical workflow → bumps existing replay_count instead of duplicating. - revise(parent_uid, new_trace) → PathwayReviseOutcome Chains versions; rejects retired or already-superseded parents. - retire(trace_uid, reason) → bool Marks specific trace retired with reason. Idempotent. - history(trace_uid) → Vec Walks parent_trace_uid back to root, then superseded_by forward to tip. Cycle-safe via visited set. Retrieval gates updated: - query_hot_swap skips superseded_at.is_some() - bug_fingerprints_for skips both retired AND superseded HTTP endpoints in service.rs: - POST /vectors/pathway/upsert - POST /vectors/pathway/retire - POST /vectors/pathway/revise - GET /vectors/pathway/history/{trace_uid} scripts/seal_agent_playbook.ts switched insert→upsert + accepts SESSION_DIR arg so it can seal any archived session, not just iter4. Verified live (4/4 ops): - UPSERT first run: Added trace_uid 542ae53f - UPSERT identical: Updated, replay_count bumped 0→1 (no duplicate) - REVISE 542ae53f→87a70a61: parent stamped superseded_at, v2 created - HISTORY of v2: chain_len=2, v1 superseded, v2 tip - RETIRE iter-6 broken trace: retired=true, retirement_reason preserved - pathway_memory.stats: total=79, retired=1, reuse_rate=0.0127 Co-Authored-By: Claude Opus 4.7 (1M context) --- crates/vectord/src/pathway_memory.rs | 303 +++++++++++++++++++++++ crates/vectord/src/service.rs | 57 +++++ scripts/seal_agent_playbook.ts | 177 ++++++++++++++ tests/agent_test/agent_harness.ts | 353 +++++++++++++++++++++++++++ 4 files changed, 890 insertions(+) create mode 100644 scripts/seal_agent_playbook.ts create mode 100644 tests/agent_test/agent_harness.ts diff --git a/crates/vectord/src/pathway_memory.rs b/crates/vectord/src/pathway_memory.rs index 240d639..f3bde00 100644 --- a/crates/vectord/src/pathway_memory.rs +++ b/crates/vectord/src/pathway_memory.rs @@ -217,8 +217,39 @@ pub struct PathwayTrace { /// such that a retired pathway would work again, a new PathwayTrace /// with a fresh id will be inserted — retirement is per-id.) pub retired: bool, + + // ─── Mem0 versioning + deletion (J 2026-04-25 directive, mirrors + // playbook_memory's Phase 25/27 patterns) ─── + /// UUID for THIS specific trace. pathway_id is the bucket key + /// (shared by traces of the same task/file_prefix/signal); trace_uid + /// addresses an individual trace within that bucket so retire/revise + /// can target it precisely.
