CB-WP-0027 T01-T04: the commentary track

The meta view beside the table, and a note channel that provably cannot
carry a move.

T01 (ADR-0014). ADR-0007 D5 is SCOPED, NOT AMENDED, and the reason it was
easy is that PointerFact::parse already refuses any unrecognised field --
a comment could not reach the command path even by accident. So /command
carries pointer facts, /note carries text, and Note has no code path to
GroundCommand. Comments live in trials/<date>-<slug>.md, not in
ScenarioFile: a scenario is executed, replayed and hashed, and prose in it
is data the runner must ignore, which is how a format rots. The state hash
binds; round and step are for reading. And the retention question, decided
before any comment was written: RAW NOTES NEVER LEAVE clay-borg. A note
reaches ground-game only by being promoted to a register finding, by a
human, with the wording chosen then -- "the DARVO sequence is infuriating"
is useful signal and a bad way to open a message to the game's designer.

T02. CSS grid, minmax(0,1fr) on both tracks -- load-bearing, because a
grid child defaults to min-content width and without it the SVG table
refuses to shrink and pushes the meta column off-screen, looking correct
on the developer's monitor and broken everywhere else. Single-column
fallback under 64rem. The running tally moved into the panel so it is
visible WHILE PLAYING; it only appeared on the ending page before, and a
score you see once the game is over informs nothing.

T03. A plain <form method="post">, so the box works with the script
disabled; the command channel needs JavaScript because a drag is not a
form submission, a comment is one. 303 See Other so a reload does not
re-post. esc()'s first hostile input: <script>alert(1)</script> renders
escaped AND STILL READABLE -- escaping that eats the player's words is its
own defect. Verified over real HTTP: note posted 303, hostile note stored
as text, empty note refused 400, game did not advance.

T04. tools/trials.py and make trials. THE REPORT'S DESIGN CHANGED BECAUSE
I RAN IT: the first version called any note without a recording an orphan,
so a live session reported every note as broken -- the recording is only
written at game end. A metric that cries wolf is one nobody reads, which
is the exact failure this pass exists to prevent. Now ok / pending /
orphan, and only orphan is a target-0 number. The self-test exercises the
REPORTING path, not just the parser, because design-baseline.py had a
green self-test and an unexercised reporting path and that is where it
rotted.

And a latent Makefile defect surfaced: make trials did nothing, because
trials is also a directory and Make saw an up-to-date file. design,
difficulty and trials -- added by CB-WP-0022, CB-WP-0025 and this pass --
were ALL missing from .PHONY; only the one that collided revealed it.

make all: exit 0. 49 render tests, 26 cb-play, loop-lint clean.
