From 5c6685cb0753635a55f012feea65b1b190508ac2 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Fri, 18 Sep 2026 07:07:29 +0000 Subject: [PATCH 001/126] test(mcp): prove tracedecay_dependency_depth behavior Call the production MCP server with a fixture whose call chains are known, and assert the JSON a caller observes. The previous check only rejected one absent edge, so an empty chain list still passed.

The exact read could only borrow one already mounted on a peer checkout of the same repository (mount_query_authority_from_project_peer), and that peer's own mount is deferred until it seats a text generation. When the read landed before the main checkout's deferred mount, the borrow found nothing, the executor fell through with no authority, and execute_query_search_on_text returned the non-retryable AuthorityUnavailable above even though the branch generation was published and servable. Proven by forcing the peer borrow to yield nothing: the journey then failed 3/3 at that exact assertion with the byte-identical wire, and passes 3/3 with this change. The publication now mounts the branch worktree's own authority from the project's durable cursor-key provider once its provenance commits, so the sealed generation is queryable without depending on an unrelated worktree's activation order. It stays best effort: the generation is already committed, so a missing session mount or cursor key logs and leaves the peer borrow as the fallback. Verified under taskset -c 0-3: target test 5/5 pass, the whole cli_non_interactive_test::branch set 6/6 pass, clippy clean on tracedecay and tracedecay-cli under the CI partition lens (tracedecay/test-helpers).

Reproduced locally at ~30% under `taskset -c 0-3`. Root cause: `authority_changed` for the Cursor and Codex hook routes was derived only from the projections the pass drained itself. The projection queue is per scope and consumed on projection, and the daemon's project catch-up sweep (`ingest::project_provider::run_cursor`) drains the whole scope's queue, not just the rows it admitted. On a slow runner the scheduler tick lands between the ingest's admit and its own drain, so the ingest finds an empty queue and reports zero, discarding the two observations it had just persisted. Daemon debug evidence from a failing run: `transcript_admission_batch phase=complete total_frames=2 bytes_consumed=175 source_deferred=false` followed by `messages_upserted: 0`. Admission is the durable commit; projection is downstream materialization. Carry `observations_committed` (frames persisted) from the Cursor and Codex admit loops through to the capture outcome, count it as an authority change, and report it in the ingest payload so a zero-projection pass is readable without guessing which drainer won. A second, distinct state was equally vacuous: a pass that re-scans a source already at its stored cursor, whose rows a peer drained earlier, persists nothing and finds nothing. That is `exact_duplicate`, but Cursor had no way to say so: `CursorProjectionDrainStats::into_transcript_stats` dropped `exact_duplicates`, and `exact_duplicate` was derived only from Claude observation stats, which are always `None` for Cursor. Both gaps are closed; `JsonlObservationAdmissionProgress::resumed` supplies the evidence that a source was already admitted rather than empty, so a first-ever scan is never reported as a duplicate. A genuinely deferred pass still reports that honestly: `source_deferred` and the backpressure mapping are untouched. The acceptance assertion now accepts `committed` or `exact_duplicate` and still rejects `accepted_for_replay`. Both prove the transcript is durable; the retry path (a first pass deferred by an incomplete projection rebuild, then a re-scan of the exhausted source) legitimately terminates in the latter. Verification: `taskset -c 0-3` acceptance run 12/12 pass (was 2/6 and 0/1 before the fix, same binary shape); three new deterministic tests in `runtime::hosts::cursor::tests` cover the peer-drain steal, the replay, and the empty-source negative; `tracedecay-sessions --lib` 569/569, `tracedecay-mcp --lib` 367/367, `tracedecay-host-admission` 1/1.

Acquire it in each test body instead, matching `affected_tests_behavior_test.rs`.
