From 3a35eaf7c6b6ecf2a5f349029c3f7db76d8d1231 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/8] coord-T9: integration test suite (Gap #3) +
 fl_round_number seq fix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add internal/testutil package: MustDB (skips when OWM_TEST_DSN unset,
  runs migrations, returns pgxpool), TruncateAll, Logger, NodeFixture/Sign
- Fill in 7 skipped integration tests across 4 packages:
    registry: TestRegisterIntegration (register → activate → re-register)
    scheduler: TestScheduleIntegration, TestRequeueTimedOutIntegration
    fl: TestOpenRoundIntegration, TestSubmitGradientIntegration,
        TestTryAggregateIntegration (nil storage → placeholder fedAvg)
    stake: TestSlash_MockForceClose (mock LN, real DB, verifies
           slashing_events + node status + stake_status)
- Add migration 000009: fl_rounds.round_number now has an auto-increment
  default via a dedicated sequence (INSERT in OpenRound omitted the column;
  without a DEFAULT the insert would violate NOT NULL)

Subject: [PATCH 2/8] coord-T10: task eligibility validation (Gap #4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Migration 000010: add supported_task_types TEXT[] DEFAULT '{}' to nodes
- registry.Node: add SupportedTaskTypes []string field; persist it through
  Register upsert and return it from GetByPublicKey / ListActive
- scheduler.filterEligible: enforce task type match in addition to tier —
  a node with an empty SupportedTaskTypes list accepts all task types
  (backward-compatible); non-empty list must contain the requested task type
- New supportsTaskType() helper (pure, no imports)
- eligibility_test.go (package scheduler): 6 unit tests covering tier-only,
  empty list, mismatch, combined tier+type, nil input, and supportsTaskType table
- TestScheduleIntegration_TaskTypeMismatch: integration test confirms Schedule
  errors when no node supports the requested type and succeeds when one does

Subject: [PATCH 3/8] coord-T11: config validation hardening (Gap #5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extend validate() with four new rule groups:

Tier minimums (BRS-POS-02):
  - Each of t1/t2/t3 must meet its BRS floor (100k/500k/2M sats)
  - Ordering t1 ≤ t2 ≤ t3 is enforced; equal boundaries are allowed
  - Nil map is caught cleanly (all values read as 0)

Stake operational config:
  - verify_interval_hours, degraded_grace_period_hours, slash_cooldown_days ≥ 1
  - t1_auto_slash_signals ≥ 3 and t2t3_maintainer_acks ≥ 2 (SRS-STAKE-04)

FL config bounds:
  - min_participants ≥ 2, gradient_l2_clip_norm > 0,
    anomaly_std_dev_threshold > 0, round_interval_minutes ≥ 1,
    top_k_sparsification_pct ∈ [0, 1]

S3 group check:
  - If any of endpoint/bucket/access_key/secret_key is non-empty,
    all four must be set (partial config is rejected)

Add validate_test.go: 31 targeted tests (29 new), each mutating exactly one
field of a passing base config to verify the specific error message substring.

Subject: [PATCH 4/8] coord-T12: reliability scoring with uptime fraction (Gap
 #6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements SRS-SCHED-04: reliability = task_success_fraction × uptime_fraction
over a rolling 7-day window (clamped to node registration time).

Migration 000011: heartbeat_log table (node_id, recorded_at) with a DESC index
on (node_id, recorded_at) for efficient 7-day window queries. Includes a
pruning note for rows older than 8 days.

RecordHeartbeat: now appends to heartbeat_log on every heartbeat, preserving
the existing last_heartbeat update in the nodes table.

UpdateReliability: replaced the placeholder with three focused scalar queries
plus the Go-side computeReliability helper:
  - task_success_fraction = completed / max(total, 1)  [1.0 if no tasks yet]
  - uptime_fraction       = received_hb / expected_hb  [1.0 if window < 60 s]
  - expected_hb           = windowDuration / 60 s      (SRS-NODE-04 rate)
  - reliability           = clamp(task × uptime, 0, 1)

computeReliability is a pure function — no DB, fully deterministic.

reliability_test.go (package registry): 10 unit tests covering normal,
edge (new node, no heartbeats, extra heartbeats, sub-interval window, zero
tasks) and boundary cases; plus 2 integration tests for the full DB path.

Subject: [PATCH 5/8] ci: fix four CI failures (SSL, mTLS, observer key, gRPC
 deprecation)

- testutil/db.go: append sslmode=disable to the migration DSN so
  golang-migrate's pq driver works against the CI Postgres service
  container (no TLS configured)
- rpc/server_test.go: also accept "broken pipe" as a valid mTLS
  rejection indicator; Linux TCP stack can reset the connection before
  the TLS handshake message reaches the client
- observer/client.go: check raw-bytes length before bytes.TrimSpace in
  decodeSigningKey; binary keys whose first/last byte is ASCII whitespace
  were silently truncated, causing intermittent NewClient failures
- lightning/lnd_client.go: replace deprecated grpc.DialContext+WithBlock
  with grpc.NewClient (lazy connect, no startup timeout)

Subject: [PATCH 6/8] ci: fix three remaining test failures

- observer/client.go: gate the early raw-bytes check with !hexEncoded so
  64-char hex strings (also 64 bytes) are correctly hex-decoded rather
  than treated as a raw key; fixes TestDecodeSigningKey_64CharSeedHex
- registry/reliability_test.go: backdate registered_at by 2 hours after
  registration so the seeded historical data (heartbeats/tasks) falls
  inside the clamped window; fixes TestUpdateReliabilityIntegration
- registry/registry.go: use COALESCE(onion_address,'') in ListActive and
  GetByPublicKey so a nullable TEXT column never causes "cannot scan NULL
  into *string"; fixes TestScheduleIntegration_TaskTypeMismatch

Subject: [PATCH 7/8] ci: fix TestUpdateReliabilityIntegration window math
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pin registered_at to base-1s (1 second before the earliest seeded
heartbeat) so the rolling window is ~61 minutes.  The previous fix used
a 2-hour interval, giving expectedHB=120 against only 60 seeded
heartbeats → uptime=0.5 → reliability=0.375, failing the ≈0.75 target.
With a ~61-minute window: expectedHB≈61, uptime≈60/61≈0.98,
reliability≈0.735, safely within ±0.05 of 0.75.

Subject: [PATCH 8/8] ci: align protobuf generated file headers with CI's
 protoc version

CI installs protoc via apt-get (v3.21.12) and protoc-gen-go-grpc
(v1.6.2), then runs git diff --exit-code to guard against stale stubs.
The committed files were generated locally with v7.34.0/v1.6.1, causing
a spurious diff on every run.  Update the header comment-only version
strings to match what CI regenerates so the diff check is clean.
No functional code changes in the generated files.
