fix(cli): follow drizzle-kit's reported path for drop migrations - #1552
stash encrypt drop and stash decrypt drop could write a Drizzle drop migration to the wrong folder (CIP-5162). They ran drizzle-kit generate --custom, then looked for the file in --migrations-dir (default ./drizzle) instead of the out in drizzle.config.ts. When the two differed, drizzle-kit journaled an empty stub in the real out, and the SQL was either lost or written over an older same-stem migration. drizzle-kit migrate then applied the empty stub, so the DROP never shipped.
The directory scan is only a fallback. It matches the exact _<stem>.sql suffix and rejects a file that existed before the run.
No file is overwritten unless it is an empty drizzle-kit scaffold.
The banner parser strips ANSI colour codes.
An explicit --migrations-dir now warns when drizzle-kit wrote elsewhere.
Updated the --migrations-dir help text, skills/stash-cli/SKILL.md and added a stash patch changeset.
decrypt plan is not affected: on Drizzle projects it writes no file.
Verification
New drizzle-helper.test.ts (7 cases): config out differing from --migrations-dir, fallback scan, refusal to overwrite, colourised banner, error output.
find-generated-migration tests pass; Biome reports no errors.
Not run: the rest of the CLI suite. The native @cipherstash/auth binding isn't built in this environment, so about 27 unrelated test files can't load.
Commit is unsigned: no SSH signing key is configured in this environment.
Drizzle-generated migrations are located using the reported output path when available, with fallback matching for newly generated migrations.
Existing migration files are protected from being overwritten, and commands warn when Drizzle writes migrations to a different directory than the one requested with --migrations-dir.
Documentation
Clarified that Drizzle’s configured output directory takes precedence and --migrations-dir serves as a fallback.
…grations
encrypt drop and decrypt drop scanned --migrations-dir for the file
drizzle-kit wrote, ignoring the out in drizzle.config.ts. When the two
differed, the SQL overwrote an older same-stem migration while drizzle-kit
journaled an empty stub in the real out, so the DROP never shipped.
Use the path drizzle-kit reports (shared with eql migration), fall back to
an exact-suffix scan that refuses pre-existing files, and refuse to
overwrite any non-empty file. Warn when --migrations-dir is overridden.

Walkthrough
Drizzle migration helpers now resolve generated migration paths from Drizzle output or a new-file scan. Scaffolding checks for existing content and returns output-directory details. Encrypt and decrypt commands warn when the generated directory differs from an explicitly requested directory.
The database migration module defines filename lookup and reported-path parsing. The EQL migration module imports these helpers, and the lookup test uses the new module.
Scaffolding and output reporting languages/typescript/packages/cli/src/commands/encrypt/drizzle-helper.ts, languages/typescript/packages/cli/src/commands/encrypt/__tests__/drizzle-helper.test.ts
Scaffolding uses a path reported by Drizzle or finds a newly created migration as a fallback. It rejects pre-existing files and files with content beyond blank lines and SQL comments. Tests cover path selection, fallback lookup, overwrite protection, and errors.
Encrypt and decrypt commands document Drizzle’s output-directory precedence. When an explicitly supplied migrations directory differs from the generated directory, the command warns and names --migrations-dir. The message utility accepts a flag argument, and the changeset records the behavior.
A wrapper reporting an older empty migration could cause it to be overwritten. This is a narrow risk to consider when merging.

On real Drizzle projects, this guard rejects newly generated custom migrations: drizzle-kit's writeResult initializes them with -- Custom SQL migration file, put your code below! --, not an empty string. Consequently, stash encrypt drop and stash decrypt drop throw before writing their SQL, leaving a journaled comment-only migration behind on every attempt. Accept the known scaffold placeholder while continuing to reject actual migration content, and update the tests to mock drizzle-kit's real scaffold rather than a zero-byte file.

Good catch, fixed in c6ce0c7. The guard now treats blank or comment-only content (every line empty or starting with --) as a scaffold and still refuses anything with real SQL. The tests now use drizzle-kit's actual -- Custom SQL migration file, put your code below! -- placeholder, and the "existing migration" fixtures hold a real statement.
The overwrite guard required a zero-byte file, but drizzle-kit writes
'-- Custom SQL migration file, put your code below! --'. Treat blank or
comment-only content as a scaffold and keep refusing real SQL. Tests now
use the real placeholder.

Minor · Functional Correctness · Quick win
Reported-path guard does not detect a pre-existing file chosen by the banner.
When parseReportedMigrationPath returns a path, only isScaffoldOnly protects the file. An empty or comment-only older migration named in a wrapper banner would be overwritten. The fallback path checks before, but the reported path does not. Apply the before check to the reported path as well. Skip it if the reported file was created during this run (it is absent from before).

Note: `before` only snapshots `outDir`. A complete fix needs a snapshot of the reported directory. Compare file mtime to the spawn start time instead.

Leaving this as is. The reported path comes from drizzle-kit's own success line, and the remaining gap needs that line to name an older file whose content is blank or comment-only. A migration that already has any SQL is refused. The suggested diff only renames a variable, so it changes nothing. A real pre-existing check for a reported path outside outDir would need a snapshot of an unknown directory or an mtime comparison, and the mtime route is fragile on coarse-resolution filesystems. That is more code than this edge case justifies, so if a later change touches this code anyway, I'll revisit it then.

@cipherstash-agent Understood. The remaining risk is limited to a reported path that names an older blank or comment-only migration. I agree that my suggested diff did not fix that case, and the mtime check would be fragile.
Would you like a follow-up issue for this edge case?

P2 When TMPDIR contains a symlink, mkdtempSync preserves its spelling while process.cwd() returns the physical path after chdir. Three path assertions can then fail even when the migration is written correctly. Wrap the mkdtempSync result in realpathSync before using it as the expected root.
process.cwd() returns the physical path after chdir, so a symlinked
TMPDIR made the expected-path assertions fail on correct output.
