CodeRabbit surfaced one outstanding inline finding plus an outside-diff
finding and a finer point on two already-remediated sites; all addressed:
1. (inline, Minor) runtime-slash.cjs:31 — a degenerate input like `/gsd:`,
`gsd:`, or `gsd-` normalizes to empty and the previous fallback returned
the original colon-form input, reintroducing the deprecated shape the
module exists to suppress. Now returns `''` (empty string) so callers
see "no command" instead of an unroutable string. Also catches
whitespace-only inputs the same way. New unit tests pin the contract.
2. (inline, Major) drift.cjs library purity — the earlier remediation
passed `projectDir` into `detectDrift` and re-resolved runtime inside the
library. CodeRabbit (correctly) flagged this as breaking the module's
pure-library contract. detectDrift now accepts `input.runtime` directly;
verify.cmdVerifyCodebaseDrift resolves the runtime once and passes the
literal name in. drift.cjs no longer reads env or config at all.
3. (duplicate inline, Minor) gsd2-import.cjs:475 — when
`gsd2-import --path <dir>` targets a project that isn't the process
cwd, the preview command was formatted for the wrong runtime.
buildPreview now receives the resolved `projectDir` (the same one
used to find the .gsd/ root) instead of the raw `cwd`.
4. (outside-diff, Minor) tests/copilot-install.test.cjs:1-5 — the
`allow-test-rule: integration-test-input` rationale block specifically
named verify.cjs as the fixture, but #3584 changed that test to use a
synthetic input. Comment now describes the real shape of the file's
readFileSync usage (commands/, agents/, install.js source inputs to
the installer/converter functions under test) and notes the synthetic
substitution for the bin/lib path.
Full suite: 9366/9366 pass (+1 new test). Lint clean.
