## Thinking Path > - Paperclip manages work for AI agents. > - Server startup applies database migrations before accepting work. > - Some older embedded databases use SQL_ASCII encoding. > - Migration 0355 uses a Unicode escape literal that PostgreSQL rejects on those databases. > - A source rebuild can pass but the updated server cannot start. > - This change makes that migration portable and preserves its shipped receipt. > - Existing databases retain their newer connector triggers during upgrades. ## Linked Issues or Issue Description **What happened?** A source deployment failed at startup with `conversion between UTF8 and SQL_ASCII is not supported`. Migration 0355 could not compile its connector policy function on an older embedded database. The previous app was restored while this repair was prepared. **Expected behavior** Supported legacy databases complete startup migrations. Connector selector trimming matches JavaScript `trim()`. A database that already applied 0355 must not replay it over the later 0356 connector trigger definition. **Steps to reproduce** Create a PostgreSQL database from template0 with SQL_ASCII encoding, then apply the current migration chain. The new regression fails with the observed conversion error before this change. **Paperclip version or commit** Reproduced on `92b238137ba716cdf1746dd49969e2f5ab7af8fe`. The branch includes current master `f57ed25385`. **Database mode** Embedded PostgreSQL 18.1; legacy SQL_ASCII database. The UTF-8 path is also covered. Related background: #645 fixed encoding for new databases. Existing SQL_ASCII installations still need portable migrations. #16956 fixes a separate workspace lock timeout that motivated this deployment. ## What Changed - Build the whitespace pattern from UTF-8 bytes instead of a Unicode escape literal. - Match whole whitespace sequences so SQL_ASCII does not trim partial multibyte characters. - Recognize the original 0355 checksum as a valid receipt. This prevents replay of its older trigger body over 0356. - Add real PostgreSQL coverage for both encodings, selector behavior, and preservation of the later trigger definition and receipt count. - Document the legacy encoding and migration-history contract. ## Verification - Red: SQL_ASCII migration failed with the same conversion error; UTF-8 passed. - Second red: fixing only the SQL caused an existing receipt to replay and overwrite the later connector function. - Green: 29 focused tests passed across the new regression, migration replay tests, and database client tests. - Rebased regression: all 29 focused tests passed. - `pnpm -r typecheck`, `pnpm build`, and `pnpm --filter @paperclipai/db check:migrations` passed. - Linux ARM64: clean build and 37 focused tests passed, including both encoding and workspace-lock regressions. - Live acceptance: the same legacy SQL_ASCII database completed all seven remaining migrations. The server reports the tested commit and healthy status. The restart report has no lost runs. - All 55 current-head checks passed; two unrelated Storybook checks were skipped. Full test, typecheck, build, runner, release, and E2E CI gates passed. The complete suite ran in CI; local verification used focused tests. - Greptile reviewed this exact commit at 5/5 with no findings. - Preserved failures: the initial unmodified-master startup failed at migration 0355 and was rolled back. A later build-cache path error in the deployment commands was corrected before the successful clean build; it required no source change. ## Risks The migration content changes, so receipt compatibility matters. The original checksum remains recognized to avoid replaying historical DDL. The tests compare complete later function definitions and receipt counts. The whitespace pattern contains encoded bytes; tests cover every ECMAScript whitespace character and preserve non-whitespace Unicode input. Database data and schema shape are unchanged by this repair. ## Model Used OpenAI GPT-6 through Codex, with repository tools, code execution, and browser verification.
