kjh2064 7515b1ba81 Slice G: Apply consistent Hangfire lock timeout guards to all RecurringJob registrations (DEBT-015)
Problem: Program.cs:216 (RegisterModelOperationsSchedules) was the first
Hangfire Postgres touch at startup, with zero timeout protection. When
Hangfire.PostgreSql attempts PrepareSchemaIfNecessary and advisory lock
contention occurs, app hangs indefinitely with no logs after "Registered 12
endpoints", blocking Kestrel from binding.

Solution: Wrap all 6 RecurringJob registrations (lines 216, 226, 240, 260,
267, 273, 279) in consistent try/catch(Timeout) guards. Log WARN and continue
if lock times out, instead of silent infinite wait. Allows Kestrel to bind
even if Hangfire schema initialization is contentious.

Resolves DEBT-015 (Medium Impact / High Effort). Same pattern already existed
for outbox-poller/downstream-consumer; now applied consistently across all
scheduler jobs.

Tests: dotnet build KArtSell.sln -c Release passes with 0 errors/warnings.
Gate 3 execution will validate Kestrel startup now proceeds normally.

Quick Wins — Q3 2026 (Completed)

Rationale (per AGENTS.md v16.0 "Paydown Target: 20% quarterly"):

  • DEBT-001 (CA1822): static method hints — Completed in PR 4b. Applied static to ScheduleOccurrencePlanner.GetNextDueAt, PromotionGateEvaluator.Evaluate, EvaluationWindowPlanner.Plan; removed unnecessary DI registrations (+1 pt).
  • DEBT-002 (CA1873): array logging — Already compliant: all logging uses LoggerMessage delegates. Verified in PR 4b build with CA1873 enabled: 0 warnings. No action needed (+0 pts, marked "No Action").
  • Result: +1 pt resolved (25% of 4pt target). Target rate achievable by completing additional small-effort items from remaining backlog.

Batch During Feature Work

  • DEBT-001, DEBT-002 — Moving to Quick Wins (PR 4 priority)

Monitor & Defer (No Action)

Rationale (per AGENTS.md "Keep in backlog; revisit if conditions change"):

  • DEBT-003 (CA1305 culture): Locale formatting. Accept as-is for Serilog. Breaking change risk > benefit. Status: Permanently defer
  • DEBT-004 (CA1707 test naming): xUnit convention (underscores). No fix needed; convention not a defect. Status: Permanently defer
  • DEBT-005 (CA1861 array overhead): Static readonly arrays. Negligible perf; readability priority. Status: Permanently defer
  • DEBT-006 (xUnit2031 filter): Assert.Single overload vs .Where(). Style preference, not safety. Status: Permanently defer
  • DEBT-008 (Namespace consistency): Per-project AssemblyName intentional (DLL clarity). No action needed. Status: Accepted
