The database mount below was one of three ways the decoder could not reach its
own oracle. The other two are here.
`run-canary` never looked in `Checked/`. It tried `Release/` then `Debug/`, and
both of those exist on this box -- an Aug 28 binary and a Jul 19 one. They boot
the game perfectly well and carry NO `audit_61` branch probe, so a probe run
against either returns zero hits that read as a finding about the game rather
than as a stale binary. Configuration is now the outer loop and location the
inner one, so a `Checked` build anywhere beats a `Release` build anywhere;
`$XENIA_BIN` still overrides everything. Measured here: `Checked` has
`audit_61_branch_probe_pcs`, `Release` and `Debug` do not.
The launcher also now says which instrumentation is missing BEFORE the run,
because the alternative is reading an empty log afterwards and guessing.
`build-canary` built `$PROJECT_DIR/xenia-canary`, which does not exist in this
container -- the source is bind-mounted at `/canary` and the launcher already
exports `XENIA_SRC=/canary`. CONTAINER-NOTES has carried that defect since
2026-08-29 with a symlink workaround and a warning to remember to delete the
symlink afterwards. It now reads `$XENIA_SRC` first, so there is nothing to
remember. Its default configuration moves Release -> Checked to match what
`run-canary` picks; the old default spent a full build on a binary nothing ran.
Two documented blockers are refuted rather than deleted, since the sequence of
wrong readings is what makes the right one checkable: the CONTAINER-NOTES
symlink dance (the warm build volume it was configured against is gone too,
removed in the 2026-09-18 cleanup, so the next build configures cleanly against
`/canary`), and `upstream-baseline.md`'s "`version.h` is never generated" --
`CMakeLists.txt` generates it at configure time now, with a stub fallback.
`decoder-loop.md` claimed the oracle was at `Linux/Release/` and that the probe
was on two side branches; both were true when written and neither is now.
Verified: five pick_bin cases against the extracted function body, and `strings`
on all three real binaries.
