Use a unique ownership key for reused virtual sources.

resetBlankedEnvVars stores one owner per source key. These calls pass a project directory for source identifiers that can be reused by multiple instances: the well-known URL, "OPENCODE_CONFIG_CONTENT", and ${url}/api/config.

When Project B loads one of these sources, it deletes Project A's record and assigns ownership to Project B. Project A then loses its diagnostics.

Use a project-qualified source key for project-scoped sources. Pass ConfigVariable.SHARED_CONFIG for sources that are process-wide. Keep any internal scoped key separate from the display source.

Clear diagnostics when an optional source disappears.

These resets run only when the source has content. A missing or invalid remote configuration returns before Line 168. An empty OPENCODE_CONFIG_CONTENT skips Line 629. A missing organization configuration skips Line 659.

If a source was loaded earlier, its old blanked-variable names remain visible after the source is removed. Move each reset and ownership declaration before its optional-source guard.

WARNING: Shared config sources are scoped to a single project, dropping their blank-env diagnostics for every other project

OPENCODE_CONFIG_CONTENT (here), the account/org remote config ${url}/api/config (line 659), and the well-known remote config (line 168 / projectDir: ctx.directory at line 495) are process/user-wide — every instance loads identical content — so a blank {env:VAR} in them affects every project and should be reported to all of them.

Scoping them to ctx.directory means that in a serve process with two live projects, only the last project to load wins _sourceOwner for these sources, so blankedEnvVars(projectA) silently drops the shared warning (and, if the projects differ, may attribute it to the wrong one). This contradicts the PR description ("OPENCODE_CONFIG_CONTENT, a remote config URL — remain visible to all of them") and regresses the pre-ownership behavior, where the path-based filter treated non-absolute sources as shared. Use ConfigVariable.SHARED_CONFIG as the owner for these three call sites instead of ctx.directory/input.projectDir.

Reply with @kilocode-bot fix it to have Kilo Code address this issue.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Keep shared TUI configuration sources shared.

load() handles global, managed, and project-local files. Line 110 assigns every source to ctx.directory. A later load from another project overwrites the owner of a global source. The first project then loses its unresolved-variable diagnostic.

Pass ownership into load() or mergeFile(). Use ConfigVariable.SHARED_CONFIG for global and managed sources. Use ctx.directory only for project-local sources.

SUGGESTION: _sourceOwner grows without bound in a long-lived server

Entries are added on every resetBlankedEnvVars (line 60) and are only ever removed by the test-only resetAllBlankedEnvVars. A long-lived altimate serve process accumulates one entry per distinct config-source path it has ever loaded (each project's opencode.json/altimate-code.json, and every well-known/org URL), with no eviction path in production. This is the same slow leak this PR just fixed for discover.ts's per-project buckets. Storing the owner alongside the names — e.g. Map<string, { names: Set<string>; owner: string }> — would let a reset drop the entry when a source is never re-added, instead of a parallel map that outlives every source.
