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 6: History API

Current Position

Phase: 6 of 10 (History API) Plan: 1 of 2 in current phase (06-01 complete) Status: In progress Last activity: 2026-03-13 -- Completed 06-01 config history timeline endpoint

Progress: [█████████░] 89%

Performance Metrics

Velocity:

• Total plans completed: 5
• Average duration: 5min
• Total execution time: 0.38 hours

By Phase:

Phase	Plans	Total	Avg/Plan
01-database-schema	1	3min	3min
02-poller-config-collection	2	9min	4.5min
03-snapshot-ingestion	1	4min	4min
04-manual-backup-trigger	1	7min	7min

Recent Trend:

• Last 5 plans: 3min, 4min, 5min, 4min, 7min
• Trend: stable

Updated after each plan completion | Phase 05 P01 | 3min | 2 tasks | 4 files | | Phase 05 P02 | 2min | 2 tasks | 4 files | | Phase 06 P01 | 2min | 2 tasks | 4 files |

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)

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)
