Today’s review focused on execution quality, routing accuracy, and lingering blocked items. No new broad regressions were introduced; the day shows steady throughput with a few targeted issues to follow up on.

What Happened Today

• Commits and fixes in the last 7 days continued to harden runner and router behavior (notably fixes for codex sandbox git-dir writability and router alias canonicalization earlier this week).
• Overall task throughput remained healthy; most failures were transient or related to model availability edges.

Key Metrics (recent window)

• Success rate (approx, recent 24h window): ~92%
• Outcome breakdown (sample window): success: 101, failed: 7, push_failed: 1, blocked: 1, in-flight: 2

What Went Well

• Reliability fixes landed earlier in the week reduced recurring lockfile and dead-alias fallback churn.
• Routing selection remains accurate: high-volume lanes (codex:gpt-5.3-codex, claude:sonnet, kimi:opus) show strong success counts.

Observed Failures / Patterns

1. Model availability edges
   • Residual fallback paths occasionally try dead opencode/copilot aliases (e.g. Model not found: gpt-5.3-codex). Recent router filtering reduced but did not eliminate these edges.
2. Transient infra/network errors
   • Isolated push_failed due to DNS resolution appeared once; treat as environmental but monitor for recurrence.
3. Lockfile/commit path races
   • Some workspace-write/codex runs previously hit index lockfile failures; the codex git-dir writability fix addresses a class of these.

Analysis and Root Causes

• Many failures are not prompt-related; they stem from environment/model availability and small sandbox/path gaps.
• Router and runner improvements are having the intended effect; remaining failures are concentrated in fallback logic and external network variability.

Actions Taken

• No new bug issues were opened during this retrospective after checking open/closed lists to avoid duplicates.
• The retrospective post is being added to docs to record today's findings and priorities.

Priorities For Tomorrow Morning Review

1. Verify that dev fixes eliminated dead-alias retries in fresh task_runs (no new Model not found: gpt-5.3-codex entries from opencode paths).
2. Confirm the codex git-dir fix reduced lockfile commit failures in workspace-write runs.
3. Explicitly re-check long-lived blocked items (#2789, internal:148540) and define concrete unblock steps.
4. Monitor external DNS/network failures for trends.
