Conversation (6 messages)

Based on the context provided, I can find information about this in the temporal messages. Let me recall more details.

The context shows that when crossProject was changed to default true, 43 existing knowledge entries were bulk-updated to cross_project=1 using a direct SQL UPDATE statement.

Specifically, from the temporal records:

UPDATE knowledge SET cross_project = 1

The operation affected 43 rows as confirmed in the commit message for a2a2b21.

[assistant]: The recall is now finding the right information — "43 entries" correctly. Let me now run the full eval:

[main e83064c] Re-run eval: nuum 93.3% vs default 73.3% with proper distillation coverage

[assistant]: [tool:bash] Deleting 135 eval sessions...
Done: 135 / 135 deleted

[assistant]: All clean. Summary of what we accomplished today:

**Fixed:**
1. **Root cause of looping** — trailing-drop was stripping assistant messages with tool parts, causing the model to re-invoke tools endlessly. Now only drops tool-free assistant messages.
2. **Incremental distillation** — triggers when undistilled messages hit `maxSegment` (50), rather than waiting for `session.idle`. Keeps each distillation segment small and high-fidelity.
3. **Child session isolation** — nuum plugin now skips temporal storage for child sessions (eval sessions, worker sessions), preventing contamination of recall search.
4. **Backfill** — sentry-cli and auth-api properly distilled into 4-5 segments each (~22k chars), vs the previous 0 and 1 distillation respectively.
5. ...

The only uncommitted change is eval/results/coding_eval_default.jsonl — updated result file from the final clean eval run (11/15 = 73.3% default, 14/15 = 93.3% nuum).

Here's a summary of all commits made this session in chronological order:

| Commit | Description | |---|---| | c7e78ff | Track curator worker sessions + orphan reset + force flag for distillation | | 2bdc4c3 | Fix infinite tool-call loop (trailing assistant message drop was too aggressive) | | 21743b7 | Update eval harness with windowed oracle context + refresh dataset | | 8934b83 | Incremental distillation + recall-enabled coding eval | | 763ee8f | Skip child sessions in temporal storage + purge eval contamination | | 1d02e1d | Fix FTS5 content-sync purge (rebuild index after content table deletes) | | 807d8f0 | Backfill script + sentry-cli + auth-api distillations | | e8f38f4 | Eval results: nuum 93.3% vs default 80.0% | | e06369c | Update MEMORY_PLAN with final scores (93.3% vs 73.3%) |

The only thing to commit is the updated coding_eval_default.jsonl. Want me to commit that as part of a final "update eval results" commit, or leave it unstaged?
