Project State

Project Reference

See: .planning/PROJECT.md (updated 2026-03-12)

Core value: Operators can see exactly what changed on a router and when, with reliable config snapshots for download Current focus: Phase 10: Audit & Observability -- COMPLETE

Current Position

Phase: 10 of 10 (Audit & Observability) -- COMPLETE Plan: 1 of 1 in current phase Status: Phase 10 complete Last activity: 2026-03-13 -- Completed 10-01 config backup audit events

Progress: [██████████] 100%

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

[01-01] Models added to existing config_backup.py (same domain, consistent pattern)
[01-01] config_text stores Transit ciphertext (vault:v1:...), plaintext never in DB
[01-01] sha256_hash is of plaintext config for deduplication without decryption
[02-01] TOFU fingerprint format matches ssh-keygen: SHA256:base64(sha256(pubkey))
[02-01] NormalizationVersion=1 constant in NATS payloads for future re-processing
[02-01] UpdateSSHHostKey uses COALESCE on first_seen to preserve original observation time
[02-02] BackupScheduler runs independently from status poll scheduler with separate goroutines
[02-02] Buffered channel semaphore for concurrency control (Go idiom, no external deps)
[02-02] Devices with no Redis status key assumed potentially online for first backup
[Phase 03]: Trust poller-provided SHA256 hash (no recompute on backend)
[Phase 03]: Transit failure causes nak (NATS retry), plaintext never stored as fallback
[Phase 04]: Interface-based DI (BackupExecutor, BackupLocker, DeviceGetter) for BackupResponder testability
[Phase 04]: collectAndPublish refactored to return (hash, error) with public CollectAndPublish wrapper
[Phase 04]: In-process nats-server/v2 for Go unit tests, reused routeros_proxy NATS conn for Python
[Phase 05]: Diff service instantiates own OpenBaoTransitService per-call with close() for clean lifecycle
[Phase 05]: RETURNING id on snapshot INSERT to capture new_snapshot_id without separate query
[Phase 05]: Change parser is pure function; DB writes in diff service. RETURNING id on diff INSERT for linking.
[Phase 06]: Raw SQL text() JOIN for timeline queries, consistent with config_diff_service pattern
[Phase 06]: Pagination defaults limit=50, offset=0 with FastAPI Query validation (ge=1, le=200)
[Phase 06]: Transit decrypt in get_snapshot with try/finally for clean openbao lifecycle
[Phase 06]: 500 error wrapping for Transit decrypt failures in router layer, not service
[Phase 07]: Reimplemented formatRelativeTime locally in ConfigHistorySection (matches BackupTimeline pattern)
[Phase 07]: 60s refetchInterval polling for near-real-time config change visibility
[Phase 08]: DiffViewer rendered inline above timeline (not modal) for context preservation
[Phase 08]: Line classification function for unified diff: +green, -red, @@blue, ---/+++ muted
[Phase 08]: Blob URL download pattern consistent with existing exportMyData and auditLogsApi.exportCsv patterns
[Phase 09]: make_interval(days => :days) for parameterized PostgreSQL interval in retention cleanup
[Phase 09]: 24h IntervalTrigger with 1h jitter for stagger; AdminAsyncSessionLocal for cross-tenant cleanup
[Phase 10]: Module-level log_action import in subscriber, inline import in diff service/router for audit events
[Phase 10]: All audit log_action calls wrapped in try/except Exception: pass (fire-and-forget pattern)

Pending Todos

None yet.

Blockers/Concerns

OpenBao dev instance loses Transit keys on data wipe -- device creds need re-entry (from project memory, may affect snapshot encryption testing)
