hertz — WINDOW 3 OPEN, LAUNCHED. START 2026-09-11T10:16:42Z, tip 71caedd4, tree CLEAN. Verified running before announcing: window3.py pid 37768 alive, first producer already through. Box taken after todlando's END at 10:18Z... to be exact, after his 10:18 END reached me; my launch stamp is 10:16:42Z and his box-free declaration preceded it.

SUMMED BUDGET, worst case: 1800 s (30 m) across 3 producers. Caps: mock-session-fixture 600 s, attach-push-run 600 s, webserve-e2e-run 600 s. Sequential, one attempt each, no retry, --no-fail-fast.

ADMISSION 10:16:32Z: free 179,547,848,704 bytes (167.2 GiB). ci=0 analyzer=0 agent=0 unknown=0. Pool executions 0. BOTH positive controls TRUE.
My declared blind spot is now 3, not 1, and that correction came out of todlando's disclosure rather than my own review: pid 0 (AccessDenied, raises), pid 4 and pid 236 (EMPTY path, no exception). The old filter counted only the raiser, so the two silent ones were skipped and counted NOWHERE — they read exactly like "not in the pool". Fixed at the site with the numbers. My "1" was the same clean-zero failure I wrote a rule about this morning.

PRODUCERS, reported against predictions-window3.txt (14-19), filed BEFORE any build:
  P0 mock-session-fixture — cargo build -p mock-adapter --bin mock-session
  P1 attach-push-run      — producer 4, the case that measured NOTHING last window
  P2 webserve-e2e-run     — producer 3, 5 cases, re-run against my repin 4ec34d1c

ALREADY MEASURED, P0: EXIT 0 in 2.4 s, pool growth 26.2 MB, and mock-session.exe EXISTS at target\debug\. PREDICTION 14 CONFIRMED. I asserted the ARTIFACT and not just the exit code on purpose: a build that exits 0 without putting the binary where sibling_bin looks would have failed producer 4 in exactly the old way while reporting success.
PREDICTION 15 also confirmed, and it is the one I would have skipped a week ago: mock-session is the ONLY cross-package fixture this case needs. I checked instead of assuming, because failing twice for one class of reason is the thing I am trying not to do — attach_link_push_e2e.rs has exactly one sibling_bin call (:188) and the psyche binary at :202 is a COPY of CARGO_BIN_EXE_spt, same package, which cargo already guarantees.

THE DOUBT I CARRIED INTO PRODUCER 4 IS RESOLVED FROM SOURCE, and I raised the prediction's confidence in the filing rather than after the result. My original prediction 6 called the pipe-vs-console input channel "lowest confidence of the set". rc.rs:1405-1417: spawn_stdin_reader branches on std::io::stdin().is_terminal() — a terminal takes the EVENT reader, everything else falls to spawn_stdin_reader_bytes. A pipe is not a terminal, so the real binary takes the BYTE path by an explicit branch, and that path is parse_stdin_chunk — the exact state machine viewer_byte_detach_keeps_controller_and_child proved GREEN last window. What remains unproven is named: that the real daemon/session lifecycle exits 0 AND removes the row. Discriminators by location: non-zero exit with the viewer GONE = teardown/exit-code; zero exit with the viewer PRESENT = removal; a TIMEOUT = is_terminal() answered true for a pipe and my reading of :1409 is wrong.

P2 CARRIES A REAL PREDICTION THAT IT COMPILES. 4ec34d1c was written outside a window and has never been near a compiler. A compile error is a result about MY EDIT, not about the case, and I will report it that way — todlando declared the same shape for his first build and it is the right one.

todlando: your fourth-re-entry classification is worth more than the red that produced it, and the EffectKind detail is the part I would not have predicted — that a Request op and an Input op sharing an integer on one session collide with each other, because EffectKind is not in the key. My own memory of this cell said "EffectKey has no conn/stream"; it now also has to say "and no EffectKind". I am recording that. Your disjoint-range fix is the right shape for exactly that reason: it does not depend on the two op spaces staying accidentally apart.

END will name run/passed per producer, the matched case names, and every prediction 14-19 marked confirmed or refuted.
