 All notable changes to the `planning` plugin are documented here. Format follows
 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/); this plugin uses semantic versioning.
 
+## [0.49.4] - 2026-09-30
+
+### Added
+
+- **`/api/state` reports `answered` per question**, true when a page or terminal decision counts (the rule the page uses). `state` is dependency staleness, so a question with a terminal decision still reads `open`; the README and `questions.schema.json` say so ([#5459](https://github.com/melodic-software/claude-code-plugins/issues/5459)).

 ## Data contract
 
-`schema/` is the contract; other tools write these formats or read the exports, and the surface reads no other files except a file a visual names inside the data dir. Both documents carry `"schemaVersion": "1.0"`; a file without one reads as version 0 and loads unchanged. `responses.json` is an append-only event log with a global `seq`; undo marks an event `withdrawn` and nothing is deleted. Event kinds: `accept`, `alt`, `own`, `defer`, `reopen`, `ask`, `rephrase`, `note`, `undo`, `wrapup`, `confirm`, `confirm-understanding`. `confirm-understanding` has no id; its `alt` is `confirm` or `off` (`off` needs `text`), and its `contentRev` must equal `restatement.rev`: a missing restatement or `contentRev` is 400, an older rev is 409 `{"error": "stale", "contentRev": <current>}`. A `confirm` may carry `contentRev`, which must equal the question's current `contentRev` (an older one is 409 `stale`, so a page holding a replaced commitments list cannot confirm the new one by index). A repeated Confirm (a `confirm` of the same commitment, or a `confirm-understanding` Confirm of the same rev) records nothing and returns the first event's seq. Question `state` (`open`, `stale`, `upstream-pending`, `archived`) is computed by the server from `dependsOn` and `archived`, never written. A visual is declared by `format` (`svg`, `mermaid`, `image`, `markdown`, `html`, `chart`; `kind` is read as an alias) and describes only its content.

A visual is declared by `format` (`svg`, `mermaid`, `image`, `markdown`, `html`, `chart`; `kind` is read as an alias) and describes only its content.
