v0.25.0

Refresh .floppy/run: no. The shim is untouched — no commit in this
release reaches shim/run.

Minor by the 0.21.0 rule: no file layout moved and no migration is needed, but
a rite reads differently — wrap's skill is a tenth shorter and the evidence
behind its rules now sits beside it rather than inside it.

wrap stops carrying its evidence through the hot path

Section 5 held about 750 words of measurement: the 48-run turn study, the
quadratic-cost arithmetic, the superseded explanation of the fold. All of it
is load-bearing when a rule is questioned and dead weight when the rite is
merely run — and the rite is run every session. It moves to
skills/wrap/measurements.md next to the skill, referenced by name rather
than @-imported, so it is read when a rule is being changed and not before.
The rules themselves stay inline with their numbers. 3082 → 2744 words.

The rewrite-once rule gets a price, because the bare count never argued

The rule carried "2.6 edit turns per run on that one file" and no consequence.
A count alone argues for nothing, and this one has never held: re-measured
across five repositories a week later it is 2.7, the same before the
mid-session capture convention as after. What was missing is what a turn there
costs — a median 32k base-equivalent tokens, almost all of it re-reading the
context rather than writing the text. That is what makes patching the
expensive option even though each call looks small: two patching turns cost
64k where one full rewrite costs 49k with the whole file in its output, and at
the p90 of six turns the gap is 143k.

knowledge-rot-check.py gets the timezone slack the other two linters had

Both CI legs went red on verified_on is in the future: the date was written
at UTC+3 in the evening while the runners were still on the previous UTC day.
The same off-by-one was measured on 2026-09-05 and fixed then in
memory-lint.sh and translation-check.py — this third linter was missed.

In the same pass, the knowledge note on the Opus 5 delegation line was
re-verified against Claude Code 2.1.267. Its recheck grepped the binary for a
whole 2.1.232 literal, which the release reworded, so the gate failed while
the behaviour was unchanged; it now greps the sentence's middle, which is what
survives a rewording.

The field survey becomes a page of the site

docs/comparison.md and its Russian translation — floppy among eight memory
systems — join the page table in scripts/site-build.sh.
