Closes #5453

#5183 (branch queen-5158, merged 2026-09-29) replaced tools/check_seal_coverage.py, 688 lines, with the single line # No changes made to this file; only the baseline was updated. The Queen's verdict on that issue was escalate: she did not accept it. An empty Python file exits 0, so coverage and its --self-check negative control have reported success since then while checking nothing.

This restores the file byte-for-byte from bcb32d723^.

Measured locally, at master, with t27c built from master's bootstrap/

  • python3 tools/check_seal_coverage.py --self-check exits 0. Every planted case lands on the right branch, and the legend covers 8 of 8 kinds.
  • python3 tools/check_seal_coverage.py exits 1: 649 seals do not hold (540 stale, 109 gen-drift). There were 131 when the gate was removed.

Expect coverage to be red on this PR. That is the restored instrument telling the truth. coverage is not among master's required checks today (validate, check-linked-issue, parse-ratchet), so it blocks nothing.

Not done here, and an owner decision: re-sealing the 649, or which of them are spec bugs rather than seal debt. #5158 said so itself.

#5183 (branch queen-5158, merged 2026-09-29 with the Queen's verdict
`escalate`) replaced tools/check_seal_coverage.py, 688 lines, with
"# No changes made to this file; only the baseline was updated." An empty
Python file exits 0, so the coverage job and its --self-check negative
control have reported success since then while checking nothing.

Restored byte-for-byte from bcb32d7^. Measured at master with t27c built
from master's bootstrap/: the self-check passes; the real run reports 649
seals that do not hold (540 stale, 109 gen-drift), up from 131 when the gate
went. Re-sealing them is the owner's decision (#5158 said so); this restores
the instrument, not a verdict on the 649.

Closes #5453

…ds changes, and after a red ratchet (Refs #5453) (#5489)

tools/check_gate_preconditions.py runs six gates on an empty tree and
names any that exit 0 with nothing to check. Given master's one-line
tools/check_seal_coverage.py it says, in under two seconds:

    VACUOUS   check_seal_coverage.py [bare] exits 0 with nothing to check

It never got to say it, for two independent reasons:

- fpga-build.yml listed only two of the six gates in its path filters,
  so #5183 -- which emptied check_seal_coverage.py on 2026-09-29 and
  touched nothing else but a docs/now entry -- never started it.
- Since a90bdac (2026-09-22) every master run of fpga-conformance has
  failed at "Elaboration errors may fall, never rise", and GitHub skips
  every later step, this control included.

So the other four gates in its table and tools/_prereq.py (which it
plants them with) join both path lists, and the step runs with
`if: always()`, the idiom bootstrap-tests and corpus-ratchet already
use. It reads the built t27c and the tree, never the ratchet's verdict;
when t27c did not build it reports UNRUN, which is red and true.

On this PR the step is expected to report VACUOUS for
check_seal_coverage.py: master still carries the one-line file until
#5454 lands.
