# Changelog

## Unreleased

- Add native remote compaction v2 for `sub-api` with `openai-responses`, using the configured public Responses URL and gateway authentication.
- Restore SubAPI native checkpoints on subsequent requests and preserve the existing Codex transport, portable model-switching summary and failure fallback.
- Cover provider eligibility, URL/authentication handling and both providers' native checkpoint lifecycles with offline tests.
- Preserve explicit SubAPI Authorization headers over API keys, support header-only Authorization/proxy authentication, and reject missing credentials without weakening Codex JWT requirements.
- Pass small tool results through unchanged: projection now replaces a tool result only when the summary plus its `Source:` recovery line is strictly shorter than the original text content.
- Preserve original content parts, including non-text parts, for every tool result that is not replaced. Indexed evidence remains recoverable through `context_tree_query` either way.
- Align the implementation with the documented "replace large tool results" behavior; add regression tests for pass-through and for recoverability without replacement.

## 1.0.0

- Introduce one incremental Context Authority for provider requests, threshold decisions, UI metrics, and native compaction.
- Add deterministic tool-result compaction with source-backed recovery.
- Add a bounded asynchronous semantic-summary worker.
- Add Codex remote compaction using the effective projection rather than the raw Session branch.
- Add portable checkpoint text for provider/model switching.
- Add `context_tree_query` and `/compaction-status`.
- Deliberately omit legacy pi-condense and Codex checkpoint/config compatibility.
