fix: isolate per-organization aggregation failures

[yyiilluu]

Summary

A repair, claim, or finalization exception from one organization currently aborts the rest of the aggregation scheduler tick. Continue processing later organizations and defer the failed organization for five minutes, preventing a persistent storage failure from monopolizing subsequent ticks.

Changes

• Catch organization execution failures independently from context-provider failures.
• Use a monotonic five-minute cooldown and clear it after a successful attempt.
• Record repair-attempt time before storage access so failed repairs respect the existing interval.
• Log the organization and failing stage; preserve sequential execution, durable retry rules, lease durations, and lease fencing.
• Document failure isolation and add repair/claim/finalization failure, cooldown/recovery, provider failure, and healthy-organization completion regressions.

Test Plan

• 93 tests passed: scheduler, aggregation lineage, soft deletion, and SQLite aggregation-state integration tests, including lease-loss rejection.
• Ruff lint/format and Pyright passed for changed Python files.
• No request or response schemas change.

Summary by CodeRabbit

• Reliability

  • Processing now continues for healthy organizations when another organization encounters a failure.
  • Failed organizations are temporarily deferred before retrying, reducing repeated failures.
  • Recoverable context-provider and repair failures no longer interrupt processing for other organizations.

• Diagnostics

  • Logs identify the affected organization and processing stage, making failures easier to understand.

📝 Walkthrough

Walkthrough

The aggregation scheduler now tracks execution stages, isolates organization failures, defers retries for five minutes, continues processing later organizations, and logs stage-specific failures. Tests and documentation cover throttling, recovery, and provider failures.

Changes

Scheduler resilience

Layer / File(s)	Summary
Stage tracking and retry suppression reflexio/server/services/playbook/aggregation_scheduler.py	The scheduler records execution stages, timestamps repair attempts, suppresses retries after organization failures, clears suppression after success, and labels context-provider failures.
Resilience validation and documentation tests/server/services/playbook/test_aggregation_scheduler.py, reflexio/server/services/playbook/README.md	Tests cover failure isolation, retry throttling, recovery, and stage-specific logs. The README documents sequential processing and five-minute deferral.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c26dc

The scheduler now isolates organization failures and retries them after cooldown, but aggregation-operation failures lack the intended stage-specific diagnostic field. This does not change retry behavior, but it reduces operational visibility for one failure path.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Include the aggregation stage in the local failure log.

When aggregation work raises, _run_context catches the exception and finalizes the claim. The organization-level handler does not run. The retryable_failed log therefore has no stage=aggregation, despite the stage set on Line 172. Add the explicit stage field to that log and add a regression test for an aggregation-operation failure.
