Phase 1 of AUDIT-2026-Q3.md item P1.1.
app/main.py was referenced by Makefile, AGENTS.md, CONTRIBUTING.md,
and external `uvicorn app.main:app` invocations, but the file did not
exist (refactored to app/factory.py in a prior session — the docs were
never updated). This restores the canonical entrypoint.
The reported symptom (AttributeError: module 'bcrypt' has no attribute
'__about__') was misleading. passlib 1.7.4 (the latest released version
— the project is unmaintained) actually traps that AttributeError with
a bare `except:` and continues. The real failure occurs later in
`passlib.handlers.bcrypt._finalize_backend_mixin`:
detect_wrap_bug -> verify(secret, bug_hash)
where secret = (b"0123456789"*26)[:255] # 255-byte test secret
bcrypt 4.0+ removed silent 72-byte truncation and now raises
`ValueError: password cannot be longer than 72 bytes`, breaking the
backend probe and crashing every `pwd_context.hash()/verify()` call.
Three options were considered:
A. Upgrade passlib — impossible, 1.7.4 is the latest PyPI release.
B. Pin bcrypt<4.0 — conflicts with chromadb 1.1.1 (>=4.0.1 required),
even though chromadb's bcrypt usage is optional and still works
at runtime in practice.
C. Shim bcrypt.__about__ — doesn't fix the actual truncation error.
Chosen: refactor app/auth.py to use bcrypt directly for backup-code
hashing too (the main `hash_password`/`verify_password` already did).
Drops the passlib dependency entirely, restoring bcrypt 5.x for chromadb
compatibility and eliminating the unmaintained passlib pin.
Verified:
* hash_password / verify_password round-trip OK
* _hash_backup_code / _verify_backup_code round-trip OK on
freshly generated 8-digit backup codes
* `pytest tests/unit` -> 717 passed, 32 warnings, 60 subtests passed
Gitleaks flagged 4 production secrets in rmi-backend source:
app/caching_shield/solana_tracker.py: st_ZMzXzdUI54TXQPx5E6JkG
app/databus/arkham_ws.py: ws_Z5x09Rcr_1780418740765322917
app/routers/webhooks_router.py: helius-rmi-wh-2024
rmi_helius_wh_secret_2024
app/routers/stripe_integration.py: pk_test_51Tn13MAXseReicQtM...
Each replaced with os.getenv() reads. Placeholder env lines added to
/srv/rmi-infra/.env.secrets. Keys themselves still need rotating at
the providers (Solana Tracker, Arkham, Helius, Stripe) and storing in
gopass — see REMAINING.md.
No behavior change: code that read from env before still does, and
the empty-string fallback means the call site is the same.
Note: this commit scrubs the keys from the working tree. They remain
in git history. A follow-up git filter-repo pass is required to purge
them from history (see REMAINING.md). After that, all clones and
external remotes must be force-updated.
