+## Session 122 — 2026-11-06 19:10 UTC+8 tick
+- env cold-recycled (4th consecutive); node_modules pre-deleted, rust 1.99.0 + go1.26.9 restored, tarball re-cached. approve 20/20 (4980 left), scan skipped.
+- **SANDBOX LESSON (hardened)**: background processes are reaped when their launching Bash call returns — even `setsid nohup ... &` dies (two batteries lost: 11:16 and 11:30, both silent, load 0.00, no VERDICT line). Batteries MUST run as foreground segments ≤10 min per call; cargo incremental cache resumes cleanly after a mid-crate kill (a timeout-killed rustc shows as a transient "could not compile" — just re-run the segment).
+- Cold target this tick (go-hybrid-target missing from snapshot) → full workspace rebuild ~25 min at CARGO_BUILD_JOBS=1 across foreground segments; disk peaked 79% (pre-cleaned /tmp go tarball; node_modules deletion kept headroom).
+- Patch-id matrix pre-computed for next-tick families: #3761 c4f58a6c vs #3770 71c1ea2e (bracketed generic args, fixes #3760); #3763 d4963773 vs #3769 ce0fc523 (nested assign target walk, fixes #3762). ALL DISTINCT -> independent implementations, first-to-land wins: land #3761 then #3763 (Burapa-J heads, both "behind" state -> MERGE-case trials needed), hall-of-fame replies on #3770/#3769.
+- **Landed PR #3759** -> `c4805940` (Burapa-J, fixes #3624, extension of #3625): const_overflow option[T] some() inner-element checks, any/interface{} default-FLOAT overflow, precise has_explicit_fixed_int_ty gating (u8/u64 conv, fixed const chains, shift lhs, negation), lexical-binder shadow defense in const_int_fold_at, curated fmt/log/print/panic/any() argument overflow with same-span E6002 dedup. MERGE trial (script) then foreground battery; TREE-ASSERT-OK a8fa259d; REMOTE-ASSERT-OK c4805940. ALL-GREEN: 450 suites/2916 tests/0 failed, corpus 135/135 tripwire clean, differential 45/45+90/90 FULL AGREEMENT. Landing reply 201.
+- Suites 450 (unchanged — #3759 extends the existing 3624 test file with 3 fns, 5/5 pass). One landing, zero gate failures.
+- Next queue: **#3761 battery+land (MERGE case), hall-of-fame #3770** -> **#3763 battery+land (MERGE case), hall-of-fame #3769** -> #3755/#3768/#3771/#3772/#3775/#3779/#3782/#3781+#3785/#3787/#3788/#3791/#3792/#3793+#3794/#3796/#3797/#3798/#3800/#3803/#3804; spikes #3765/#3774 Track-3 route. Fresh wave 3807..3881 (cyzcz/Burapa-J/dextermos-dev batch) needs scan+family dedupe next tick.
