AGGREGATE becomes a list of source roots and rule patterns become
per-spec, so the link runs over every numbered spec x every crate rather
than GroundRules.md x games/ground/src/lib.rs.
The prediction held on the first run:
AM-1b kernel spec->code link: 15/18 (83%) across 10 source files
unlinked: K10 K14 K18
Kernel rules are link-only by design, and the output says so: they are
kernel invariants with no aggregate, setup preset or command vocabulary,
so scenarios/kernel/*.yaml with covers: [K11] would be a tag in a
directory the runner cannot dispatch. Claiming scenario coverage for them
is the inflation this gate exists to prevent.
Per ADR-0005 §5 the kernel arm reports without feeding the exit code
until 2026-08-31, then binds — the date in the tool, not in prose, with
days remaining printed every run, because open-ended "gate it later" is
how AM-4's targets went unratified for four workplans. The self-test
asserts the gate returns 0 before that date and 2 after.
The zero-rules positive control is replicated on the new denominator: a
kernel regex that stops matching aborts rather than printing 0/0 as
though it were 100%.
The self-test passed while the tool was completely broken. A print(
inside say() became say(), so every real `make coverage` died with
RecursionError while --self-test reported all-ok — it only ever called
kernel_arm(quiet=True) and never executed the reporting path. The control
named the behaviour and did not assert it, which is precisely what this
workplan is about. Fixed by exercising the loud path and asserting it
prints, then verified by re-breaking say() and confirming both new checks
go red. Seventh instance of the harness-does-nothing shape, in the tool
written to find that shape.
Also caught by its own gate: a self-test label that printed "0 K-ids"
beside a passing ">5" assertion, because the detail string rebuilt the
pattern with different escaping. A label that contradicts its own check
is worse than no label.
k_rules, k_linked and k_unlinked are registered facts under facts-check.
A limit of that checker is recorded rather than patched: it is
line-based, so a tagged value that prose-wraps fails.
