Included review availability: Your plan includes up to 10 reviews per rolling hour; 6 remain after this review. 📝 WalkthroughWalkthroughAdds per-model OpenAI auto-compaction budgets. The budgets are validated, clamped against context and input limits, propagated through catalog discovery and synchronization, exposed through provider management APIs, and covered by catalog, convergence, configuration, and management tests. ChangesPer-model auto-compaction budgets
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The new per-model compaction policy can produce catalog entries whose compaction or input limits exceed effective provider bounds, while configured Sol budgets may be reduced unexpectedly; this can cause ineffective compaction or invalid runtime metadata, so the PR needs fixes or explicit owner acceptance before merge.

Inline comments:
In `@src/codex/catalog/metadata.ts`:
- Around line 150-153: Update the gpt-5.6-sol metadata declaration and its
adjacent comment so the auto-compaction budget matches the shared 90% clamp of
829,800 tokens: either lower autoCompactTokenLimit to that effective ceiling or
remove the ineffective override and describe the shared limit accurately.
In `@tests/claude-models-discovery.test.ts`:
- Around line 222-226: Update the test loop over
config.providers.openai.modelAutoCompactTokenLimits to assert
auto_compact_token_limit equals expected for both the bare slug and the
corresponding desktop/ account-qualified slug, preserving the existing
configured-value expectation for each row.
In `@tests/codex-convergence-contract.test.ts`:
- Around line 415-426: Guard the end anchor in the contract test by storing the
index of "// Field-mask editor", asserting it is found and occurs after
handlerStart, then slicing between the validated anchors. Keep the existing
assertions scoped to the canonical ChatGPT provider handler.
In `@tests/management-provider-validation.test.ts`:
- Around line 3105-3108: Update the test’s management API dependency object to
provide createManagementConvergeCodex using the existing
catalogConvergenceFactory, matching the wiring used elsewhere in the file. Keep
refreshCodexCatalog only if required by the route, and ensure the test uses the
stubbed convergence implementation instead of dynamically importing real catalog
convergence.

lookup and merged fields so autoCompactTokenLimit is clamped after contextWindow
is backfilled from replaced. Ensure the published budget never exceeds the final
merged contextWindow, including when customContextWindow is undefined, while
preserving existing values when no window is available.
