Do not let config archiving abort recovery.
archiveBrokenOpenCodeConfigFile() awaits readOpenCodeConfigSnapshot() and writeHealthWatchArtifact() without a catch. If either operation rejects, the settings rollback returns 500 before deleting the broken config or restarting. The supervisor records seedDefaultConfig() as a failed recovery action before it can seed the default config or restart. Archiving only provides diagnostic data, so catch archive errors, log them, and return null.
🛡️ Proposed fix to keep the archive best-effort
export async function archiveBrokenOpenCodeConfigFile(): Promise<string | null> {
- const snapshot = await readOpenCodeConfigSnapshot()
- if (snapshot.sources.length === 0) {
- return null
- }
-
- const payload = serializeOpenCodeConfigSnapshot(toOpenCodeConfigFile(snapshot))
- const archivePath = await writeHealthWatchArtifact(OPENCODE_CONFIG_SNAPSHOT_ARTIFACT_PREFIX, () => payload)
- logger.warn(`Archived broken OpenCode config to ${archivePath}`)
- return archivePath

Problem
The manager treated
opencode.jsonas the only global config file, but OpenCode mergesconfig.json,opencode.json, andopencode.jsoncfrom the workspace config directory in that order. Anything set in a source the manager did not read was invisible in the UI and could silently override what the UI wrote.Saves had two further problems: they rewrote the whole file as JSON, dropping JSONC comments and formatting, and they applied the config to the running server through the OpenCode API patch, which could silently drop fields OpenCode rejected (
removedFields).Fix
opencode-config-file.tsreads every existing source, deep-merges them in OpenCode's order (later file wins), and exposes the merged content, the per-source files, and arevisionhash over the source set and raw contents.jsonc-parsermodify/applyEditsinto the preferred writable source (opencode.jsonc, thenopencode.json, thenconfig.json), preserving comments and inherited values. Removing a key deletes only its override in the write target.PUT /opencode-configacceptssourceandexpectedRevision. A stale revision returns409with the expected and actual revisions; an unknown source returns400. Saves never silently drop unsupported fields.config-recovery.tsand the API patch path are removed. The manager writes files and restarts;OPENCODE_CONFIGis no longer injected, so OpenCode discovers all sources itself.reloadConfigrestarts the server and routes through the restart coordinator when one is attached.opencode-config-brokenhealth-watch artifacts before seeding or deleting; last-known-good config is stored as a multi-source snapshot instead of a single file body.GET /opencode-config/effectiveproxies the running server's/global/config; the manager tool allowlist and assistant instructions document the merge order, revision guard, and the separate effective endpoint.Testing
