Two test files cover the voyage-code-3 default landed in the previous
commits:
test/gbrain-init-voyage-code-3.test.ts — free, deterministic, gate-tier.
Mirrors gbrain-init-rollback.test.ts: runs the skill template's
PGLite-init bash against a fake \`gbrain\` that logs argv to a sentinel
file, asserts the right flags pass under VOYAGE_API_KEY set/unset/empty.
Also includes belt-and-suspenders grep checks that the template literally
contains the voyage gate at all 3 PGLite init sites.
test/gbrain-sync-voyage-code-3-integration.test.ts — real, paid,
skip-if-no-key. Inits a sandbox PGLite with voyage-code-3 in a tempdir,
registers a 3-file fixture git repo as a source, runs
\`gbrain sync --strategy code --skip-failed\`, asserts pages imported +
embedded > 0. Also asserts \`gbrain doctor\` reports no dimension
mismatch and the column width is 1024d. \`gbrain code-def\` smoke test
confirms symbol extraction works against the embedded fixture.
The integration test deliberately omits a \`gbrain query\` assertion:
query produces correct output but \`gbrain query\` hangs ~2 min on a
fresh PGLite before exiting. The smoking-gun assertion for "embeddings
worked" is the "N pages embedded" line from sync output. Symbol-aware
correctness is covered by the code-def assertion.
Caught one real bug during test development: gbrain reads
\`.gbrain-source\` from CWD and tries to sync that source too. The test
sets cwd to the sandbox root to avoid the parent worktree's pin
polluting the sandbox brain. Documented in the runGbrain() helper.
Runtime: ~22s when VOYAGE_API_KEY is set, instant skip otherwise.
Cost: ~\$0.001 per run (3 tiny fixture files, ~500 tokens of Voyage
embeddings).
