All remaining backend files renamed:
src/middleware/auth.ts, logging.ts (2 files)
src/utils/*.ts (20 files: ai, auditQueue, config, crypto,
embeddings, errors, fileType, logger, models,
notify, passwords, platform, promptSafe,
prompts, redact, sessions, transcribe*,
ttsGoogle)
src/db/database.ts, migrate.ts (2 files)
Spot-fixes to satisfy tsc (all within the spirit of 'no behavior
change' — added `: any` annotations where the original JS relied on
duck typing that tsc's default inference narrows too aggressively):
utils/ai.ts — body, converseParams, request literals + fallback
result object + err.code/model/message casts. AI client has lots
of provider-specific ad-hoc object shapes; Day 5 will replace the
`any`s with proper provider-response interfaces.
utils/embeddings.ts — payload + request as `any`; generateEmbedding
call sites pass `undefined as any` for the now-required second
arg (model) until we refactor the signature.
utils/prompts.ts — PROMPTS typed as Record<string, any> so
.loadFromDb / .updatePrompt / .getAllPrompts attachments after
the const literal compile.
utils/transcribeLocal.ts — buildArgs() has two `var args = [...]`
in the same function scope (var-hoisted); both now typed as
any[] so they don't type-clash across conditionals.
Backend is now 54 of 54 TypeScript files, permissive mode.
`npm run typecheck` EXIT 0. Prod container still running the old
JS image — no Dockerfile change yet.
Next: Day 5 flips strict: true, fixes every error tsc surfaces, adds
Vitest + Zod + Knip tooling.
