From 18c21d63085e6f4d77cb289ac97d80cfde5acd21 Mon Sep 17 00:00:00 2001 From: Rolando Santamaria Maso Date: Wed, 22 Jul 2026 13:52:34 +0200 Subject: [PATCH 1/7] fix(memory): phase 1 tails - tool honesty, session save lock, combined extraction, curator provenance - memory add_atom now reports 'quarantined for human review (reason: ...)' instead of 'added atom' when the guard scan routed the atom to quarantine, so the agent (and user) are not misled about what landed in the live store - session Store.Save no longer holds the store mutex during embedding (a potential 10s HTTP call); vector-index add happens after the lock is released, persistence semantics unchanged - session-end extraction uses ONE combined LLM call (summary + facts in a single JSON response) when both episode and fact extraction are enabled, with automatic fallback to the two single-purpose calls on parse failure; all existing safety filters preserved - curator MergeSkills keeps the WORSE provenance of the two inputs (Untrusted/NeedsReview = OR, Sources = deduped union) instead of inheriting the keeper's trust while concatenating a tainted body --- internal/memory/extract_combined_test.go | 149 +++++++++++++++++++++++ internal/memory/memory.go | 92 ++++++++++++-- internal/memory/tool.go | 45 +++++++ internal/memory/tool_test.go | 59 +++++++++ internal/session/session.go | 61 +++++++--- internal/session/session_test.go | 53 ++++++++ internal/skills/curator.go | 31 +++++ internal/skills/curator_test.go | 83 +++++++++++++ 8 files changed, 544 insertions(+), 29 deletions(-) create mode 100644 internal/memory/extract_combined_test.go diff --git a/internal/memory/extract_combined_test.go b/internal/memory/extract_combined_test.go new file mode 100644 index 0000000..dab28ca --- /dev/null +++ b/internal/memory/extract_combined_test.go @@ -0,0 +1,149 @@ +package memory + +import ( + "context" + "strings" + "sync" + "testing" +) + +// mockResp maps a system/user prompt substring to a canned response. +type mockResp struct { + prefix string + resp string +} + +// countingLLM is a mockLLM variant that counts SimpleCall invocations and +// matches responses in a deterministic (slice) order. +type countingLLM struct { + mu sync.Mutex + calls int + responses []mockResp +} + +func (m *countingLLM) SimpleCall(_ context.Context, system, user string) (string, error) { + m.mu.Lock() + defer m.mu.Unlock() + m.calls++ + for _, r := range m.responses { + if strings.Contains(system, r.prefix) || strings.Contains(user, r.prefix) { + return r.resp, nil + } + } + return "", nil +} + +func (m *countingLLM) callCount() int { + m.mu.Lock() + defer m.mu.Unlock() + return m.calls +} + +// combinedCfg enables both episode and fact extraction with background +// consolidation off, so the session-end LLM call count is deterministic. +func combinedCfg() MemoryConfig { + cfg := factsOnConfig() + cfg.ConsolidateOnEnd = boolPtr(false) + return cfg +} + +// When both episode and fact extraction are enabled, a single combined LLM +// call populates both stores. +func TestExtractCombined_SingleCallPopulatesBoth(t *testing.T) { + dir := t.TempDir() + llm := &countingLLM{responses: []mockResp{ + {"single JSON object", `{"summary":"fixed the parser bug in lexer.go","facts":[{"scope":"user","fact":"User prefers tabs over spaces"},{"scope":"env","fact":"Project is Go and tests run with go test"}]}`}, + }} + mm := NewMemoryManager(dir, llm, combinedCfg()) + + mm.OnSessionEndWithProvenance("20260601-combined", 5, threeTurns, EpisodeProvenance{}) + + if got := llm.callCount();
