refactor: restore runtime module boundaries and remove obsolete paths - #239
Merged
Merged
Conversation
Separate turn snapshots, task scheduling, provider transports and database repositories so each module owns one responsibility. Enforce application layering and remove execution helpers superseded by native Pydantic AI runs. Preserve validated state and accumulated usage, roll back partially started services, and propagate database failures consistently. Add regressions for the confirmed defects.
Keep memory-only prompt snapshots with their session, drain lifecycle shutdown despite repeated cancellation, and let shared database error handling serve every artifact route. Restrict the settings import exception to the assistant configuration schema.
An oversized response could leave the reader task's exception unobserved and detach the process before its pipes were closed. Drain and reap the failed subprocess before waking dependent calls, and assert complete cleanup in the existing failure regression.
Keep waiter failure and closure delivery unconditional if draining is interrupted, and let normal server shutdown await reader finalization after process exit. Cover shutdown with an outstanding RPC and subscriber.

Merge Risk: ⚪ Minimal · up to Malformed Codex schema entries no longer hide supported methods, and shutdown handles the process-exit race. Normal startup rollback and shutdown protect cleanup from cancellation, leaving no actionable merge-blocking risk in the supplied context.

57-65: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueType the token fields in
CodexCliAuthasSecretStr.
CodexCliAuthholdsaccess_token,refresh_token, andid_tokenas plainstr. Arepr()of the model, or a traceback or log that includes it, prints the raw tokens. The service passes this object around (sync_from_codex_clicalls_use_codex_cli_auth(tokens)), so accidental exposure is plausible.Use
SecretStrfor these fields. Call.get_secret_value()in_use_codex_cli_auth.CodexSession.access_tokenhas the same exposure, but I did not trace its consumers, so check them before changing it.This is a hardening change. The current code does not log the tokens.
Based on learnings: "type sensitive fields (passwords, API keys, tokens, secrets) as
SecretStr(orSecretBytes) instead of plainstr."🤖 Prompt for AI Agents

Continue collecting method names from valid variants so malformed entries do not
hide the others.

Recent additions concentrated unrelated responsibilities in turn execution, background tasks, provider adapters, and persistence. This restores the existing module boundaries and strengthens import checks so application services cannot depend on transport edges.
Validation: Ruff and formatting pass; 2,966 tests pass with one database-dependent skip. All 202 compatibility tests also pass with Pydantic AI 2.40. The voice cleanup regressions also passed with unraisable warnings treated as errors. Database validation runs in CI. Three surveyor reviews completed. Local review used separate CLI processes at high effort: an initial Claude Fable round found four medium issues (all fixed); Astra reviewed the full final diff and found one P2 shutdown race (fixed); Astra's follow-up found no actionable regressions and passed 20 focused shutdown checks. A further Astra high follow-up cleared both CodeRabbit corrections with zero findings. Four completed local review rounds; mis-scoped or interrupted attempts are excluded from the gate. Final reviewed head:
ebe3b7d.Scope: 75 files, +3,200/-3,112 lines, mostly responsibility-preserving moves. No new features or schema changes. README and architecture invariants updated to match.
Part of #83.
