[Jamkris]

Summary

Round 3 audit log. ECC moved 67 commits forward of the baseline recorded at the end of round 2 (#71 reported 65 when the drift tracker opened; ECC merged 2 more before triage).

Notable findings

• df60af9 (code-reviewer guardrails) — adds Pre-Report Gate, HIGH/CRITICAL proof rules, "zero findings is valid" guidance, and a Common False Positives catalog to ECC's code-reviewer agent. All harness-agnostic. Port target.
• 393d397 (prompt defense baselines) — adds a uniform 6-bullet prompt-defense block to ECC's CLAUDE.md and every agent file (71 files total upstream). Port target — apply to EGC's GEMINI.md and all agents.

Deferred (8 net-new features)

ECC added meaningful new surfaces this round that exceed a sync-round port scope: PRD planning command, network architect agents, motion system skills, Quarkus handling, Django Celery workflow, cost tracking + skill scout, frontend design guidance, homelab config skills. These join the deferred net-new candidates from round 2 (tinystruct-patterns, ios-icon-gen, flox-environments) — should be opened as a dedicated "ECC net-new" PR set in a future round.

Follow-up PRs

1. `port: code-reviewer guardrails + prompt defense baselines from ECC`
2. `docs: sync upstream baseline to 393d397` — closes #71

Test plan

• `npm run lint` clean
• `npm test` 279/279
• Doc-only change

Walkthrough

This PR adds upstream/sync-rounds/2026-05-13.md, a triage inventory document for the ECC→EGC synchronization round dated 2026-05-13. It records 65 commits of drift, enumerates triage outcomes across eight categories (skills, agents, docs, needs-review, shared-logic, ci/packaging, other-harness, meta), summarizes port/defer/skip counts, lists suggested follow-up PRs, and explicitly marks deferred net-new items out of scope for this round.
