## Summary
Retire the prerelease private OpenCode installation completely as an
executable source. Automatic selection now uses PATH and the
conventional shared user npm installation. Existing private files are
neither migrated nor deleted.
- Remove the private installer, receipt reader and fallback
introduced/retained by #756.
- Ignore saved private selections and reject validation/launch from
`~/.local/share/codenomad/opencode`, including private PATH entries.
Prevent installation into that retired prefix.
- Remove private-copy descriptions from all ten locales and update the
runtime policy documentation.
- Keep supported custom installations, native shared-service
ownership/authentication and explicit restart behavior.
## Reproduction and scope
The initial genuinely empty-profile test passed, but it did not match
the affected machine: that machine had no Git and retained a private
prerelease OpenCode copy.
On the exact installed `v0.20.0-dev-20260923-baf674fc` Tauri artifact,
seeding a valid private copy plus its `selected` receipt and `current`
marker makes setup report `state: ready`, `installationSource: legacy`,
and suppresses the missing-installation screen. The new desktop
regression fails against that release with `ready !== missing`.
With rebuilt server/UI resources in an isolated copy of the same Tauri
host, the identical private-copy scenario reports missing, offers
installation, installs the shared npm package, authenticates OpenCode
2.0.15 and resumes the requested folder without Git. This demonstrates
the missing-setup cause; it does not claim to explain every initially
reported startup slowdown.
## Validation
- 59 targeted server tests passed: discovery/install/update, retired
paths, binary selection, Windows/WSL spawn and binary validation routes.
- 13 real-component setup browser tests passed.
- 23 focused retirement/launch tests passed after the final network-path
preflight adjustment.
- UI TypeScript check passed; production server/UI/automation/pruning
build passed.
- Installed-release private-copy reproduction failed as expected;
corrected isolated Tauri acceptance passed.
- `git diff --check` passed.
Desktop qualification uses isolated profiles, services and databases.
The sole simulated installation side effect is HKCU PATH registration,
captured by a fixture preload; bundled npm installation, package
verification, native-parent service start and authenticated API checks
are real. The shared user daemon and installed application were not
replaced by the fix. Remote CI is pending.
## Maintenance notes
Existing oversized files touched: `packages/server/src/api-types.ts`
(~583 lines) and `packages/ui/src/lib/i18n/messages/*/settings.ts`
(~625–639 lines). No size-only refactor is included.
Replace the arbitrary 2.0.11 floor with the 2.0.7 native step-timestamp boundary, keeping 2.0.11 as the separately recommended qualification target. Unlisted, prerelease and custom runtimes negotiate authenticated API requirements; preserve complete CLI labels so unknown builds neither fail solely by name nor enable unintended automatic upgrades.
Finish retiring pre-2.0.4 location/worktree/credential/Form serialization and obsolete catalog events while preserving internal identity, import/cursor authorization, pruning claims and connection fences. Remove the unused global package-manager installer and clean generated server output before packaging so deleted modules cannot survive incremental builds.
Distinguish missing setup, technical incompatibility and optional updates in the shared UI, including minimum rationale and optional restart wording. Retain a usable daemon through older discovery CLIs, check reload capability independently, and suppress installation when bundled npm is unavailable.
Validated 622 server tests, 7 browser scenarios, real reducers and fixture guards, production native suites on 2.0.7 and 2.0.10, and synthetic 2.0.3-to-2.0.7 history migration. Independent gatekeeper re-review closed the production version-parser finding. CI now qualifies the source-defined minimum and latest; rebuilt desktop acceptance is recorded separately.
Do not treat a newer CLI's stopped status as proof that its older shared daemon is absent. Resolve native service metadata read-only through the selected execution host, match the channel's credential/configuration unambiguously, and authenticate historical metadata routes before admitting the registered endpoint. Repeat discovery inside ensure before starting.
Fail closed for malformed or oversized records, ambiguous identity, authentication failures, timeouts and existing WSL registrations with forwarding errors. Distinguish fresh configuration with no native registration, preserve the shared loopback policy including 127.0.0.2, and translate mounted/aliased WSL metadata through the selected distro.
Add lifecycle regressions and bounded, isolated packaged desktop acceptance. Both rebuilt Electron and Tauri retain an actual 2.0.3 daemon through installation until explicit restart, then activate 2.0.11 and resume the pending folder. Normal installation/reload and all three WSL modes pass. Final gatekeeper review reports no actionable findings; full server suite passes 621 tests with two skips.
