dtourolleandClaude Opus 5 71354e862a docs: VR-013 and VR-014 results; AR-002 raised to 40px
Records study results and the requirement change that follows from them.

VR-013 measures minimum face size end to end — gallery from one recording,
probes from another — rather than by degrading an already-aligned crop. Holding
90% of the plateau needs ~50 px that way against VR-005's ~22 px, the gap being
detection and landmark error rather than the embedder. AR-002 therefore takes
40 px, not 32: VR-005 isolates the embedder and is an upper bound, and 32 admits
faces in the falling region. FPI stayed 0.0% at every scale, and the ceiling is
cross-view rather than resolution.

VR-014 exercises audio-signature offset recovery on real film audio instead of
the synthetic golden tone. Forty random in-cap offsets, every one recovered to
the nearest frame, worst error 46 ms against a 500 ms budget — and 46 ms is the
quantisation floor rather than a result, since offsets land on whole 92.88 ms
frames. The runtime/2 anchor is confirmed through head-trimmed files.

The soft spot VR-014 found is tier labelling, not accuracy: the score drops with
sub-frame misalignment, so 27 of 40 correct alignments were demoted to `loose`.
One frame of slack in the score restores all forty to `audio` with false matches
unmoved.

Denominators are read from [`requirements.md`](requirements.md) at run time, never hardcoded. Coverage counts a requirement only when it is tagged in source **and** has a verification tier this repo's CI host can execute (`T1, T2, T3, static`).

## Not executable in CI
These requirements have no verification tier this repo's CI host can run, so a tag on them is evidence of *intent*, not of verification. They are never counted as covered.

**Tagged but unexecuted:** AR-027, VR-001, VR-002, VR-003, VR-004 — a test exists and is tagged, but this CI host cannot run it. Report those runs separately.
## Orphan tags
A tag naming an ID `requirements.md` does not define. This is what renumbering produces, and what a typo produces.
_None._
## Requirements tracing up to nothing
A register row whose `Traces to` cell names no parent. Work serving no stated goal is how scope creeps in, and it is invisible unless something looks.
_None._
## Recorded exceptions
Deliberate, documented departures from an invariant (`EXCEPTION: XX-nnn <reason>`). Reported separately and never counted as coverage — an exception is a decision to be reviewed, not evidence a requirement is met.
_None._
