 - uberWAVE reads ngspice RAW (binary or ASCII). Its `wp2-parser/golden/top.spice` (SAR ADC, xschem, IHP SG13G2) is GPL-2.0: test against it at run time, never vendor it.
 - A module-level one-element array literal `[798915]` lowers to a Zig array type (#10512); write `[798915] ** 1` until it is fixed.
 - Seal only with `ZIG_GLOBAL_CACHE_DIR` set in a sandboxed session: otherwise the seal's test run cannot create the zig cache and the seal records a false "blocked" verdict plus a home path, which turns `scan` red (#10521). Never write a home path into a committed file; derive it from `git rev-parse`.
+- 2026-10-19 Closing a Terminal tab kills the script running in it (a remote-job poller and a ledger patch were lost this way); read the tab or wait for the script's marker file before stop_terminal_tab with close. Remote containers started with docker run -d survive and can be fetched again. (#11063)

+- 2026-10-19 The L1 check reads every commit message of a PR for Closes/Fixes/Resolves/Refs/Updates #N and rejects 'Part of #N'; pushed history is not rewritten, so tell lane agents to end each commit message with 'Updates #N' before the first push. (#11106)
+- 2026-10-19 One seal the emitter PR did not re-save (ml_host_io_model after the gen-verilog fix) turns coverage and spec-guards red on master for every open PR; read 'tools/check_seal_currency.py' output for the one name, and run it with TRI_T27C set when the tree has no target/. (#11102)
+- 2026-10-19 On a Mac a spec that no longer compiles under Zig cannot be re-sealed: 't27c seal --save' refuses, rightly. If gen_hash_zig, c and rust still MATCH in 'seal --verify', the recorded test pass is still the evidence for that Zig and only the moved hash is set, to the value verify prints; say so in the PR.
