* test: fix environment-dependent failures on built and partial-clone checkouts
Canvas A2UI fixtures now pin the resolved root through a new canvas
test-api hook: dev checkouts with a locally built a2ui.bundle.js won
candidate resolution and shadowed the fixture root. Speech-core prefs
tests resolve the canonical tmpdir (macOS /tmp symlink breaks fs-safe
store roots), and the bundled plugin install test asks discovery for
the canonical bundled path instead of hardcoding the source tree.
* fix(release): keep evidence verifier blob reads local-deterministic
git show against a forged or missing SHA lazily fetched from the
promisor remote on partial clones, hanging a security check on network
state (266s observed). GIT_NO_LAZY_FETCH pins verification to local
objects; missing blobs fail closed as before.
* perf(test): pay the command-handler barrel once and merge subagent command tests
commands-name and commands-login imported the full handler barrel
(~1,700 modules) for registration assertions; those now live in a
dedicated registration test, dropping the two files from 12.6s/4.6s to
1.4s/1.0s locally. Five subagent command test files merged into one so
the auto-reply module graph evaluates once instead of five times.
* perf(ci): stripe node test bins by measured file cost
Round-robin striping packed the whale files together, leaving
auto-reply-commands-1 at ~220s while sibling stripes idled at ~30s.
Greedy LPT over advisory per-file seconds hints balances the commands,
cli-runner, and tooling stripes deterministically; group hints for the
restriped bins are equalized at the old totals.
