has_match/count_lines in _wake-common.sh: rc 0 -> match, rc 1 -> no-match,
anything else -> loud abort naming the call site, the raw exit code, and the
arguments — an error never becomes a verdict. The abort escapes subshells,
pipelines, and $() substitutions by signalling the suite's main shell, so
the suite dies verdict-less; loudness survives call-site 2>/dev/null via a
wake_assert_init-saved stderr fd (dynamically allocated >= 10, no collision
with the wake lock fd 8 or detector run-loop fd 9).
Validate instrumentation (evidence only, inert in production):
WAKE_ASSERT_LEDGER appends "<helper> <file>:<line>" BEFORE the grep runs, so
an aborting site's row has already landed and the counted ledger can never
go quiet in the one condition it exists to report.
WAKE_ASSERT_FORCE_GREP_ERROR_AT=<file>:<line> routes exactly that call site
through a REAL grep driven onto its real error path (rc 2) and emits a
positive ARMED confirmation first, so arm-never-matched (no ARMED line) and
error-path-broken (ARMED line, no abort) are separable on stderr alone.
validate-973/microtest-wake-assert.sh: nine checks (C1..C9) proving the
instrument before any conversion trusts it — ledger set equality across two
files, truncation detection behind an early exit, per-shape abort proofs
(subshell, 2>/dev/null canary shape, $() count capture, pipeline tail),
count-of-zero on grep rc 1, env-prefix reaching the grep child, and a
no-match arm loud by omission. All nine pass; C1 pins BASH_LINENO's
first-physical-line convention for backslash continuations, matching the
denominator artifact's coordinates.
Production tools (store.sh, ack.sh) source this file but call none of the
new helpers.

The conversion target, frozen BEFORE any conversion so completeness can be
asserted by set equality against a list that predates the batch (a control
keyed on the post-fix source can only agree with it). Derived per the amended
charter A1: frozen 257 @ 8d1d6e5 forward-mapped with per-row drift disposition
(214 unchanged / 43 moved / 0 deleted / 0 text-changed, byte-verified) UNION a
fresh six-form derivation at 089615f (self-checked by exact 257 reproduction at
8d1d6e5). Delta = exactly the four T17 sites introduced by 47f8689 (#967),
independently derived twice. A 204 (167 OR / 37 AND-inverted), count-capture 28,
B 6, C 10, D-if 9, F 4. Canaries 19 (9 same-line, 3 continuation, 7 if-form),
all AND-polarity: every one fails toward GREEN on grep error.
