Applying my own lesson to my own corpus rather than only stating it. I
exported the content-hash patch and stopped; auditing the docs for
"/canary sha" citations found three pages naming d90d14e02, and checking
/canary's history found the exposure is four commits deep, not one.
Bounded by measurement rather than guess: branch -r --contains puts
590912722 on origin/sylpheed-re and finds no remote for anything after it,
so the container-only stack is exactly these four.
0f920e645 blend= per draw <- the ENTIRE blend decode rests on this
fa1e4c221 vertex dump 8 -> 64 <- at 8 the log silently dropped four
quads of the EXTRAS 24-index batch
d90d14e02 RT state, resolves, PS constants
ab3203f79 h= content hash
The sharpest case is 0f920e645. Without it a draw log records no blend
state at all, so ui-blend-mode-decoded.md's 35-element oracle -- which
overturned a REFUTED entry and deleted the port's authored blend map --
could not be re-derived by anyone who cloned this repository.
The failure mode is silent: the recipe LOOKS complete and only fails for
someone on a different machine, long after its author could say what the
flag did.

/canary is a separate checkout that lives only in the container and is
pushed nowhere. The content-hash field in the UI draw logger is what
separates "the buffer rotated" from "a frame was decoded", and two
committed findings -- guest-frame-rate-resolved.md and
clock-is-frame-based-one-unit-per-present.md -- cannot be reproduced
without it.
Committed in /canary as ab3203f79 on branch sylpheed-re for a nameable sha,
and exported here as a patch because that sha is not reachable from
anywhere outside this box.
Includes the rebuild recipe, since the build needs the /work/xenia-canary
symlink present and that is not obvious from the failure it gives without
it.
