Closes #1574

Node maintenance mode (graceful drain before update/reboot)

Summary

Adds a maintenance / drain mode an admin can toggle with a signed command. Today the only
admin lever is stopNode, which kills the process immediately and loses every running compute
job and service-on-demand. Maintenance mode gives the missing intermediate state: the node
finishes what it already committed to while refusing new work, so an admin can drain it
cleanly before an update or reboot.

While maintenance is ON:

• New commitment is rejected — startCompute, freeStartCompute, initializeCompute,
  serviceStart, serviceExtend return HTTP 503 with a machine-readable
  code: "MAINTENANCE_MODE". initializeCompute is rejected before any order/payment, so
  clients never pay for an order they can't use.
• Everything already running keeps working — getComputeStatus, getComputeResult,
  getComputeStreamableLogs, stopCompute, serviceGetStatus, serviceGetResult,
  serviceStop, serviceGetStreamableLogs, and serviceRestart (no new commitment) are all
  allowed, so every running service has a known end time and the node drains predictably.
• Everything unrelated is untouched — download, DDO queries/validation, indexer, P2P,
  admin commands, fees, nonce, persistent storage, access lists, escrow events, auth tokens.

The state is persisted and sticky across restarts by design, and exit is manual only.

Design decisions

• Toggle: new signed admin command setMaintenance { enabled, nonce, address, signature },
  gated identically to every other admin command (ALLOWED_ADMINS / admin access list,
  nonce + signature). Also reachable via REST POST /api/admin/maintenance.
• Persistence: flag stored in the SQLite config DB (createOrUpdateConfig), mirrored
  by an in-memory boolean on OceanNode so the hot path (every compute/service start) never
  hits SQLite. Reloaded into the cache at startup.
• Boot flag: env MAINTENANCE_MODE lets a node boot straight into maintenance. Only exact
  true/false are honored (case/space-insensitive); any other value is logged and ignored,
  falling back to the persisted flag. Env wins at boot and is written through to the DB.
• Manual exit only: no TTL, no auto-clear on drain. When running work reaches zero the
  node stays idle in maintenance until an admin sends setMaintenance { enabled: false }.
  Because the flag is persisted, a node that reboots mid-drain comes back still in
  maintenance (prevents silent re-acceptance of work).
• Error discrimination — 503 + code: 503 is the correct "temporarily unavailable, retry
  elsewhere" family, but it is already used in these same handlers for "subsystem
  unavailable" (e.g. serviceStart → 503 "Compute engines not configured"). So clients must
  branch on the code field, not the status. Both the HTTP body { error, code } and the
  P2P frame (response.status.code) carry it. Backwards compatible: older clients still see a
  readable 503 error body.
• Visibility: status.maintenance.enabled is always present (the signal clients/dashboard
  read). detailedStatus additionally reports runningComputeJobs, runningServices, and
  latestExpectedEndTime so the admin knows when it's safe to reboot. Counts and ETA come only
  from aggregate values (no job/consumer details exposed).
• Incentives: out of scope for the node — it only exposes status.maintenance.enabled;
  how the monitor treats a draining node is handled on their side.

Changes

New files

File	Purpose
src/components/core/admin/setMaintenanceHandler.ts	SetMaintenanceHandler — signed admin command; validates enabled is a strict boolean on top of the admin auth gate, toggles and persists state
src/components/core/utils/maintenance.ts	Shared maintenanceGuard(node) + buildMaintenanceResponse() (uses import type to avoid a runtime cycle with OceanNode)
src/components/httpRoutes/maintenance.ts	REST route POST /api/admin/maintenance
src/test/unit/maintenanceMode.test.ts	Handler / OceanNode cache / status unit tests
src/test/unit/maintenanceRoutes.test.ts	HTTP/REST-level tests: 503 + code for all 5 routes
src/test/unit/maintenanceCoverage.test.ts	Transport × command coverage: real dispatch, /directCommand, REST, P2P code, allowed-command differential, persistence/restart, env-boot matrix, status/ETA
src/test/integration/maintenanceMode.test.ts	Drain-scenario integration (self-contained — runs without a live engine)
src/test/integration/maintenanceDrain.test.ts	Live free-compute drain test: starts a real freeStartCompute job, enables maintenance, proves the running job survives (status/logs/result/stop still work) while new jobs are rejected

Modified

• src/utils/constants.ts — SET_MAINTENANCE in both PROTOCOL_COMMANDS and
  SUPPORTED_PROTOCOL_COMMANDS; MAINTENANCE_MODE env var; MAINTENANCE_MODE_CONFIG_KEY,
  MAINTENANCE_MODE_CODE, MAINTENANCE_MODE_ERROR.
• src/@types/commands.ts — AdminSetMaintenanceCommand.
• src/@types/OceanNode.ts — code? on P2PStatusResponse; maintenance? block on
  OceanNodeStatus.
• src/OceanNode.ts — isInMaintenance(), setMaintenanceMode() (serialized via a write-lock;
  cache updated only after a successful DB write, else throws), loadMaintenanceMode()
  (env-override + write-through, warns on unreadable DB, guards missing sqliteConfig).
• src/index.ts — loadMaintenanceMode() at startup after the node is built.
• src/components/core/handler/coreHandlersRegistry.ts — register the handler.
• src/components/core/compute/startCompute.ts — guard in CommonComputeHandler.prepareAndAuthorize()
  (covers both paid and free start) before auth/order/escrow.
• src/components/core/compute/initialize.ts — guard before any order/payment work.
• src/components/core/service/{startService,extendService}.ts — guards before auth/escrow.
• src/components/core/utils/statusHandler.ts — maintenance.enabled set per-request (outside
  the module-level status cache so it never goes stale); detailed-only drain counts + ETA in
  try/catch with throttled logging (a node without C2D won't error).
• src/components/httpRoutes/compute.ts — initializeCompute route now branches on
  httpStatus === 200 (not stream presence) so a 503 isn't mis-sent as 200; shared
  sendCommandError surfaces { error, code } on computeStart, freeCompute,
  initializeCompute, serviceStart, serviceExtend.
• src/components/httpRoutes/index.ts — mount the REST route.
• docs/API.md, docs/env.md, .env.example, CLAUDE.md — documented the command, the
  503 + code contract, the status.maintenance fields, the MAINTENANCE_MODE env semantics,
  and the sticky-across-restarts sharp edge.

Acceptance criteria

• Admin enables/disables maintenance via a signed admin command.
• In maintenance, new compute jobs, new services, and service extensions are rejected with a
  distinct error (503 + code); status, results, logs, and stop for running work still succeed.
• The flag persists across restarts (SQLite config DB + boot reload).
• status reports maintenance state and what is still running.
• Covered by unit tests for handler gating and an integration test for the drain scenario.
• docs/API.md and docs/env.md updated.

Notes for operators

MAINTENANCE_MODE is sticky: a node that reboots while in maintenance stays in maintenance.
Returning to normal service requires an explicit setMaintenance { enabled: false } and
unsetting the env var (a leftover MAINTENANCE_MODE=false will clear a persisted drain at the
next boot).

Summary by CodeRabbit

• New Features
  • Added maintenance mode to reject new compute and service requests, including compute initialization and service extensions, while allowing existing work to be managed.
  • Administrators can enable or disable maintenance mode through a signed command or HTTP endpoint. The setting persists across restarts and can be configured at startup with MAINTENANCE_MODE.
  • Status responses show whether maintenance mode is enabled; detailed status can also report active work and its expected completion time.
  • Rejected requests return HTTP 503 with a machine-readable maintenance error code.
• Documentation
  • Documented maintenance mode behavior, configuration, and administration.

Test disabling maintenance with a signed admin request.

This test discards the handler response and disables maintenance directly. It can pass even if every admin disable request is rejected. Use an authorized signature, assert the handler succeeds, and check the resulting state without calling the setter directly.

Review comments at @src/components/core/admin/setMaintenanceHandler.ts:
- Line 23: Update the command-processing flow around `validate` to call

when no pre-runtime delay is present.

Review comments at @src/index.ts:

Fail startup if the maintenance override cannot be persisted

If the write for MAINTENANCE_MODE=true fails, the node continues with maintenance enabled only in memory. A later restart without the override can load false and accept new work.

Retry the write or fail startup. If startup fails, also block or close P2P dispatch before flushing logs: throwing alone leaves the registered handler active until the process exits.

Coordinate maintenance enable with in-flight commitments

A start or extension can pass maintenanceGuard before enable and commit after the enable response. A status check can report no running work before that commitment, so an admin can stop the node while new work is starting.

Coordinate the toggle with the lock, job creation, and extension commitment paths. Ensure admitted requests commit or abort before enable returns, while allowing already-committed work to continue. Another independent guard check would leave a race.
