Review Change Stack

Walkthrough

The change renames hierarchical routing to composite routing, updates stage-router probability handling, removes routing tier metadata, adds pre-delivery streaming fallback, and recognizes Codex apply_patch as an edit signal.

Changes

Routing and streaming updates

Layer / File(s) Summary
Routing terminology and metadata contracts
CHANGELOG.md
Routing terminology and configuration values use composite. The Classifier::routing_tier hook and tier log field are removed.
Stage-router probability selection
CHANGELOG.md
Stage-router selection uses probability thresholds, classifier fallback, picker confidence, and probability metrics.
Streaming fallback and edit signals
CHANGELOG.md
Streaming retries the next candidate when context overflow occurs before content delivery. Codex apply_patch is treated as an edit signal.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 8b090

This changelog-only PR is merge-ready after correcting one localized description that could otherwise mislead readers about composite-router configuration; no actionable merge-blocking risk remains.

Poem

A rabbit reviews the routes at dawn
Composite paths replace the old names drawn
Probabilities guide each hop
Overflow waits before streams can drop
apply_patch marks edits with a gentle pop

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the composite-router judge description.

The entry says that a composite stage router with its own judge is rejected. CompositeRouter allows this configuration. Its own judge runs before the composite router's fall-open tier. Update the entry to describe the actual restriction, such as rejecting only classify_trigger = every_request.

Understood — thanks @grahamking. I'll batch changelog catch-ups to at most once every two weeks from now on (and accumulate the uncovered commits in between, so each PR is still a complete sweep of the window).
