typescript-cli-documented-flag-silent-noop
Solution written to ~/CLI-WAIT-001-solution.md.
I located the real repo (wojons/duckbrain, branch feat/native-s3), reproduced the bug, applied the known fix (534eb78), and verified it end-to-end.
remember --wait was in the flag whitelist and usage text but never read by rememberCommand. Every write printed will be committed in batch; the commit landed only via the process-exit handler flushAllCommits(), which runs after all await points — invisible to scripts that git-verify immediately. The debounced write path returns an already-resolved promise, so naively awaiting it proves nothing.
src/git/autocommit.ts — new additive waitForNamespaceCommit(namespacePath): calls the synchronous flushNamespaceCommit to force the debounce window now, then a drainAsyncCommits-style settle loop over the per-namespace asyncChains tail (terminate when empty or already-seen).src/cli/human.ts — consume flags.wait: await the commit, print committed to git (namespace: X); on failure warn and keep exit 0 (row is already durable). Without the flag the legacy line is byte-identical.src/cli/remember-wait-cliwait001.test.ts — drives the real CLI in a scratch env-redirected root and asserts committed+clean git state immediately after exit.| Check | Result |
|---|---|
| Targeted suite (fix) | 3/3 passed |
RED control (revert human.ts) |
1 failed — only the stdout committed to git assertion; git-state assertions still pass (proving exit-flush makes git state non-discriminating) |
npx tsc --noEmit |
clean |
| Full unit suite | 158 files / 1250 tests passed |
The doc also documents the two false designs the description warned about (git-state assertions aren't a discriminator; the inverted snapshot-equality settle check returns without awaiting) and includes the full regression file.
