Read the memory notes before declaring a blocker: the recipe was there.

Sandboxed sessions: `export ZIG_GLOBAL_CACHE_DIR=$TMPDIR/zig-cache ZIG_LOCAL_CACHE_DIR=$TMPDIR/zig-local`; commit with `git -c core.hooksPath=.githooks commit`; `gh` fails TLS, use curl with `$(gh auth token)`. There is no `t27t` in this repository (searched 2026-10-18); do not invent one.

- `t27b-native-ratchet` red with only UNLISTED rows for new specs is expected: spec PRs do not edit the ledger; the steward lists them from master runs (#8656).
- 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`.
