 2. **Early critic-loss spikes**: two `1.56e16` outliers (t+6:16, t+12:04) amid otherwise sane values (~8–35) — same class as the random-init artifact flagged in #59 phase-2 notes (~1e12 there); expect decay. If persistent past early chunks, feeds the lever-5 decision.
 3. **`.part` corpses**: three `sac_latest.zip.tmp.*.part` files accumulated mid-run (libzip interrupted-write artifact, #57 forensics); harmless — atomic renames keep the main zips valid, startup sweep clears them next restart.
 
+## ~21:30 — v2 attempt-1 checkpoint finding
+
+Attempt-1's rolling zip was dead ~40 min at birth: `SACLSTM_SAVE_INTERVAL` counts **gradient steps**, and each training pass inside the short battle processes carries exactly **1 step** (the `steps=1, drained=1` signature of watch item 1) ⇒ interval-5 never reached its trigger within a process lifetime — no `sac_latest.zip` roll ever fired despite healthy training. Same class as v1's 23:32 incident, resurfacing through a different seam (per-process step budget vs per-pass step count).
+
+**Fix (env-level, no rebuild)**: `SACLSTM_SAVE_INTERVAL=1`, restart 21:09:30 CEST. Saves verified flowing: 21:09 / 21:13 / 21:16 (and still flowing at audit time — `sac_latest.zip` mtime 21:22:28, `sac_best.zip` 21:12:50). The locked-config table above keeps the original attempt-1 launch line for the record; live relaunch differs only in this knob.

+## ~21:30 — twin-freeze contract corrected
+
+`make_twin.sh` twin launcher now exports `SACLSTM_EVAL_MODE=1` (commit `19f34ab`). Without lever-4's gate on the twin side, the **v1 SacTwin had been TRAINING throughout**, not frozen — every mirror battle updated the twin's own weights. Consequence: v1's headline "**90.7% vs twin**" is retroactively an **arms-race win rate** (both policies co-evolving), not a fixed-benchmark score, and the #57 verdict phrasing implying a frozen sparring partner is corrected by this entry. No numbers change; the story does.
+
+## ~21:30 — net extended + pacing decision
+
+Slowdown attribution complete: **89% of wall clock = eval rotation by design** (`SAC_EVAL_INTERVAL=2` × 3 opponents × 10 rounds each); trainer exonerated at **~500 ticks/s**. Decision recorded in issue **#60**.
+
+Ceiling net re-armed to match the extended budget: fires **Thu 2026-08-27 07:59:40 CEST (epoch 1787810380)** — supersedes the 2026-08-23 15:59:40 fire noted under Safety net. Attempt-1 artifacts preserved in `/tmp/v2_attempt1_backup/`.
