* fix(native-chat): agents need only a minimum version for chat; newer releases and prereleases run
OpenCode chats accepted only the 1.x and 2.x lines and Pi only 0.x and 1.x,
every prerelease was refused, and a slow or failed --version run counted as
unsupported. A new major would open as a terminal and existing chats said
"Orca can't run this agent in a chat here."
Each agent now lists ascending minimum versions; a version must reach the
latest one on or below its own major line, compared by semver. The check
answers ready, too old, unknown (slow, failed or wordless run) or missing
(did not start). Only too old refuses a launch, as Codex already did, with
"<Agent> X is too old for chats. Update to Y or newer." carried in a new
optional refusal fact agentInstallation; Codex keeps sending
codexInstallation for older clients. Codex's reader and error fold into the
same check.
* refactor(native-chat): a launch check declares its minimum versions; create support and the agent health snapshot run the one shared check
* fix(native-chat): read an agent's version from stderr too, so Pi 0.73 is known too old instead of unreadable
* Require Codex 0.136.0 for native chats
* Add host-owned Codex install and update actions
* Bind Codex checks and maintenance to the selected installation
* Resolve Windows updater cleanup through system helpers
* Use one child environment for Codex checks and launch
* Expire Codex readiness and reconcile current host jobs
* Resolve Codex checks against the child command search path
* Restrict global npm repair to the selected Codex install layout
* Pin the host updater directory through Windows supervision
* Synchronize Codex maintenance fixtures on readiness
* Unify Codex notices and recover version-refused chats
* Route Codex recovery to the operation that remains
* Preserve Codex setup execution errors in the job log
* Preserve UTF-8 in Codex setup logs
* Remove unused Codex host installation detector
* Require host administration for Codex maintenance
* Show a missing Codex explanation once
* test(native-chat): give scripted Codex runtimes their installation fact; keep the registry out of the relay
Runtime tests that drive a scripted Codex app-server still ran the new
version check against whatever codex was on the machine's PATH: refused
on CI (no codex), and on a dev machine it ran the real codex --version.
A scripted transport now must state the Codex it stands for
(readCodexInstallation), asserted at install, and the tests get it from
one scriptedCodexTransport fixture.
The relay's Codex maintenance path reached @orca/windows-registry through
resolvePathEnvKey's re-export in windows-environment-path; import it from
its registry-free module instead.
Also update the catalog-probe test for the shared child environment.
* refactor(native-chat): drop the Update Codex action; keep Install for a missing Codex
A too-old Codex now gets only the plain message ("Codex X is too old for
chats. Update to 0.136.0 or newer.") with no button and no job. The
existing rechecks (window focus, the <=30 s expiry of a saved result)
retry the refused chat once the user has updated Codex themselves.
A missing Codex keeps the Install Codex button: `npm install -g
@openai/codex` with the npm on the chat's PATH, as a host-run job with
its log, then a recheck and recovery. A configured Command that is
missing gets the message only, since a global npm install would not
land at that path.
Removed: the `codex update` command and its 0.126 floor, manual
instructions, npm layout and launcher identity detection, the action
descriptor (install|update) and its titles, the legacy capability, and
the SSH relay maintenance path (structured chat never runs over SSH or
WSL), so the relay preflight handler is back to main's.
* refactor(native-chat): keep Install Codex in Settings only
When Codex isn't installed, main already hides Codex from the New tab menu,
so the in-chat Install button was almost never reachable. Settings → Agents
already shows "Codex isn't installed." with Install Codex.
- Chats and the new-workspace composer now only state "Codex isn't
installed." (no button, no install job from the chat).
- The Install action, its busy spinner and the host-busy subscription move
into the Settings Codex row, the only place that starts the job.
- The store no longer re-checks every other workspace context when a job
finishes. A refused chat recovers through the same re-check a too-old
Codex uses (window focus, or the <=30 s expiry of a saved result).
- The chat recovery key no longer includes the install job id.
- Tests: Settings drives the install; a new test proves a chat refused for
a missing Codex recovers through focus after a Settings install, not
through the job; the expiry recovery test covers missing and too old.
* refactor(codex): check chat compatibility when acquiring the child
* Restore workspace submit guard and simplify Codex maintenance
* Keep only the Codex chat minimum version
