• 🔴 (02:39) User’s upgrade path-normalization code strips a trailing path separator but never strips it from a bare root such as /; samePath(a: string, b: string) compares filesystem paths while tolerating a trailing separator.
• 🔴 (02:39) User’s upgrade source resolution contract states that the caller receives the successful probe response so it never repeats the successful source request; the implementation is resolveUpgradeSource(...).
• 🔴 (02:39) User’s upgrade implementation includes getLegacyInstallDirs(homeDir: string): string[], parseInstallationMethod(value: string): InstallationMethod, isNightlyVersion(version: string): boolean, getBinaryDownloadUrl(...), PRIMARY_UPGRADE_SOURCE = UPGRADE_SOURCES[0], and installation methods including "yarn".
• 🔴 (02:39) User’s source probing reports UpgradeError("No CLI upgrade source was found: every source returned HTTP 404") when all configured CLI upgrade sources return HTTP 404; probe cancellation recognizes errors whose name === "AbortError".
• 🔴 (02:39) User’s nightly-channel tests are in /home/byk/.local/share/opencode/worktree/0e8c2f3bbe145a3280d6fb6ed900a5121f382cf0/toolkit-bridge-upgrade/packages/cli/test/commands/cli/upgrade.test.ts; GHCR nightly checks use the /manifests/nightly endpoint and test version 0.0.0-dev.1740000000.
• 🔴 (02:39) User’s CLI tests specify that the positional argument "nightly" switches the release channel to nightly, while positional "stable" resets a previously persisted nightly channel to stable; omitting a positional channel uses the persisted channel.
• 🔴 (02:39) User’s nightly --check tests invoke ["cli", "upgrade", "--check", "--method", "curl", "nightly"], require output containing "Channel: nightly" and the valid nightly target, and require an upgrade hint when a newer nightly is available.
• 🔴 (02:39) User’s test "downloads nightly binary from GHCR for nightly channel" invokes ["cli", "upgrade", "--method", "curl", "nightly"] and verifies that at least one captured URL includes /manifests/nightly.
• 🔴 (02:39) User requires switching to nightly while using the npm installation method to trigger migration from an npm install to a standalone binary. The test "migrates npm install to standalone binary for nightly channel" calls setReleaseChannel("nightly"), invokes ["cli", "upgrade", "--method", "npm", "nightly"], and mocks a 307 redirect to https://blob.example.com/nightly.gz.
• 🔴 (02:39) User’s upgrade tests include handling the spawn error EBUSY: resource busy or locked, uv_spawn.
