Review and action non-Claude provider parity audit report

[julianknutsen]

Problem

We now have a report for the docs/non-Claude provider parity audit: w-7ed35a727f.

The earlier tracking issue, #350, was for running the audit and producing a maintainer-useful punch list. This follow-up issue is to review the actual report output, confirm which findings are still real on current main, and convert the actionable items into concrete implementation work.

Context

Related prior tracker:

• Audit non-Claude hook and runtime parity for Codex, Copilot, and related providers #350

Relevant repo context:

• engdocs/archive/analysis/gastown-upstream-audit.md
• Section 35 currently calls out two non-Claude parity themes that need confirmation/actioning:
  • hook/runtime parity for Codex, Copilot, and other non-Claude providers
  • queued/deferred nudge delivery parity for non-Claude providers

Scope

• review report w-7ed35a727f
• compare each finding against current Gas City behavior on main
• separate stale/already-fixed findings from real remaining gaps
• turn the real gaps into concrete follow-up issues or patches
• update the audit/report status so maintainers can see what remains open

Acceptance Criteria

• each finding in w-7ed35a727f is classified as one of:
  • already fixed
  • stale / no longer applicable
  • still actionable
• actionable findings are linked to discrete follow-up issues or PRs
• any confirmed parity gaps cite the relevant code/doc locations
• the resulting tracker state is specific enough that maintainers can execute the remaining work without re-running the audit from scratch

Notes

This issue is intentionally separate from #350:

• Audit non-Claude hook and runtime parity for Codex, Copilot, and related providers #350 = perform the audit
• this issue = review and action the report output
