- migration 002: use current_database() instead of hardcoded 'tod'
- ci.yml: use Go 1.25 (required by nats-server dep), mark golangci-lint
as continue-on-error until it supports Go 1.25
- go.mod: keep at 1.25.0 (nats-server v2.12.5 requires it)

- Create BackupResponder for NATS request-reply on config.backup.trigger
- Extract public CollectAndPublish from BackupScheduler returning sha256 hash
- Define BackupExecutor/BackupLocker/DeviceGetter interfaces for testability
- Create RedisBackupLocker adapter wrapping redislock.Client
- Wire BackupResponder into main.go lifecycle
- All 6 tests pass with in-process NATS server

- Test subscribe registers subscription
- Test valid request returns success with sha256_hash
- Test lock held returns locked status
- Test invalid JSON returns error
- Test Stop unsubscribes cleanly
- Test device not found returns failed status

- Create BackupScheduler with all dependencies injected
- Run as goroutine parallel to status poll scheduler
- Shares same context for graceful shutdown via SIGINT/SIGTERM
- Startup logged with interval, max_concurrent, command_timeout

- BackupScheduler manages per-device backup goroutines independently from status poll
- First backup uses 30-300s random jitter delay to spread load
- Concurrency limited by buffered channel semaphore (configurable max)
- Per-device Redis lock prevents duplicate backups across pods
- Auth failures and host key mismatches block retries with clear warnings
- Transient errors use 5m/15m/1h exponential backoff with cap
- Offline devices skipped via Redis status key check
- TOFU fingerprint stored on first successful SSH connection
- Config output validated, normalized, hashed, published to NATS
- SSHHostKeyUpdater interface added to interfaces.go
- All 12 backup unit tests pass

- Bind tunnel listeners to 0.0.0.0 instead of 127.0.0.1 so tunnels
are reachable through reverse proxies and container networks
- Reduce port range to 49000-49004 (5 concurrent tunnels)
- Derive WinBox URI host from request Host header instead of
hardcoding 127.0.0.1, enabling use behind reverse proxies
- Add README security warning about default encryption keys

Poller publishes session end events via JetStream when SSH sessions
close (normal disconnect or idle timeout). Backend subscribes with a
durable consumer and writes ssh_session_end audit log entries with
duration.

- Gap 1: Add tenant ID verification after device lookup in SSH relay handleSSH,
closing cross-tenant token reuse vulnerability
- Gap 2: Add X-Forwarded-For fallback (last entry) when X-Real-IP is absent in
SSH relay source IP extraction; import strings package
- Gap 3: Add @limiter.limit("10/minute") to POST /winbox-session and POST
/ssh-session using existing slowapi pattern from app.middleware.rate_limit
- Gap 4: Add TODO comment in open_ssh_session explaining that SSH session count
enforcement is at the poller level; no NATS subject exists yet for API-side
pre-check

Add TunnelManager, TunnelResponder, SSH relay server, and SSH relay HTTP
server to the poller startup sequence with env-configurable port ranges,
idle timeouts, and session limits. Extends graceful shutdown to cover the
HTTP server (5s context), tunnel manager, and SSH relay server via defer.

Implements the SSH relay server (Task 2.1) that validates single-use
Redis tokens via GETDEL, dials SSH to the target device with PTY,
and bridges WebSocket binary/text frames to SSH stdin/stdout/stderr
with idle timeout and per-user/per-device session limits.

Implements Manager which orchestrates WinBox tunnel lifecycle: open,
close, idle cleanup, and status queries. Uses PortPool and Tunnel from
Tasks 1.2/1.3. DeviceStore and CredentialCache wired in for Task 1.5.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implements Tunnel type that listens on a local port, accepts WinBox client
connections, dials the remote RouterOS device, and proxies traffic
bidirectionally. Uses activityReader to atomically update LastActive on
each read for idle timeout detection. Per-connection contexts derive from
the tunnel context so Close() terminates all connections cleanly.

Implements PortPool with mutex-protected allocation, bind verification
to skip ports already in use by the OS, and release-for-reuse semantics.

- poller/docker-entrypoint.sh: convert from CRLF+BOM to LF (UTF-8 no BOM)
Windows saved the file with a UTF-8 BOM which made the Linux kernel
reject the shebang with 'exec format error', crashing the poller.
- infrastructure/openbao/init.sh: same CRLF -> LF fix
- poller/Dockerfile: add sed to strip CRLF and BOM at image build time
as a defensive measure for future Windows edits
- docker-compose.override.yml: add 'restart: on-failure' to api and poller
so they recover from the postgres startup race (TimescaleDB restarts
postgres after initdb, briefly causing connection refused on first boot)
- .gitattributes: enforce LF for all text/script/code files so git
normalises line endings on checkout and prevents this class of bug
