Deploy failed on prod (MariaDB) while the test job was green: backend startup
threw during Database.Migrate(), so deploy.sh's post-deploy health check exited.
Root cause: AddCvVariants/AddAiInteractions were scaffolded against SQLite, so
they bake SQLite type names into their DDL — DateTimeOffset emits `TEXT`, bool/int
emit `INTEGER`, and the PK gets no AUTO_INCREMENT. Run against MariaDB that yields
a structurally wrong table, and the composite index over a TEXT column then trips
"ERROR 1071: Specified key was too long; max key length is 3072 bytes". SQLite
accepts all of it, which is why local/container verification passed.
Fix, following the pattern already used for CareerProfiles/AiWorkspaceNotes:
- both migrations become no-ops; the three tables are reconciler-owned
- reconciler provisions them idempotently per dialect (MySQL: varchar/int
AUTO_INCREMENT/datetime(6); SQLite: CREATE TABLE IF NOT EXISTS)
- DropMalformedMySqlTable rebuilds a half-built table left by the failed
migration, guarded on row count so a table with ANY rows is never dropped
- bound the indexed string columns with HasMaxLength so the model matches
Verified against a real MariaDB 11 container: reproduced error 1071, then
confirmed the corrected DDL yields auto_increment PKs, varchar/datetime columns
and all previously-failing indexes. 306 backend tests green; SQLite container
starts clean.

Phase 5 backend. A unified AI Workspace for each application, orchestrating the
five suggestion modules through the existing ISummarizerService provider
abstraction and storing every generation as append-only history (AiInteraction)
so outputs can be reused, compared, and deleted — distinct from the existing
AiWorkspaceNote cache (one row, overwritten).
Modules (all suggestion-only, "never invent facts" guardrail, never mutate the
profile/variant/application): job-analysis, career-match, cover-letter (6 modes),
interview, application-review. Each builds a prompt from the job + master profile
text and returns markdown.
- Models/AiInteraction.cs + migration AddAiInteractions (verified on container)
- Services/AiWorkspaceService.cs (prompts, history, delete)
- Controllers/AiWorkspaceController.cs (/api/jobapplications/{id}/ai:
generate, history, delete, modules+provider)
- 7 tests (store, history filter/order, delete, mode normalization, unknown
module, empty output, tenant scoping); 306 backend green
