+# v0.30.4
+
+Patch release fixing two issues, one of them breaking historian and dreamer runs for many Pi users.
+
+## Pi: historian and dreamer can now use models from provider extensions
+
+Pi subagents (historian, dreamer, sidekick, recomp) were spawned with extension discovery disabled. If your configured model came from a provider extension — Antigravity, Anthropic OAuth, or any other auth extension — every subagent run failed instantly with `Model "..." not found`, so the historian and dreamer never ran at all. Models defined in `models.json` were unaffected, which is why this only hit extension-based setups.
+
+Subagent processes now load your extensions, so extension-provided models resolve the same way they do in your interactive session. What changed underneath:
+
+- Recursion protection moved from disabling all extensions to a targeted guard: the full Magic Context extension detects it is inside a Magic Context subagent and stays inert there.
+- Every subagent now runs under an explicit per-agent tool allow-list. Unknown agents get no tools at all. Extension tools you have installed cannot leak into a subagent that was not meant to use them.
+- Dreamer code-reading tasks (memory mapping, verification, docs maintenance, primer investigation) now get AFT's read-only navigation tools on Pi when the AFT extension is installed, matching OpenCode.
+
+## Pi: retrospective and refresh-primers read sessions through the right API
+
+The Pi dreamer's session readers probed an API that does not exist in pi-coding-agent (`SessionManager.listSessions`), so the retrospective task failed with `Pi session APIs unavailable` and refresh-primers silently fell back to closed-book seeds. Both providers now share one resolver using the real API (`SessionManager.listAll` + `parseSessionEntries`), with tests against the installed package so a future Pi API change fails in CI instead of degrading quietly.
+
+## OpenCode: the sidebar entry in tui.json is yours again
+
+The plugin used to re-add its TUI sidebar entry to `tui.json(c)` on every OpenCode start. If you removed the sidebar deliberately, it came back on the next launch. The entry is now written only by the setup wizard and `doctor` — removing it from `tui.jsonc` disables the sidebar permanently.
