Assemble Working Context Spec (4.1)

Outcome

From any root, one command produces the OpenSpec working context its declarations describe: the resolved OpenSpec root plus referenced stores. The result is consumable as an agent brief (JSON), human listing, or optional .code-workspace file. Unresolvable references are reported, not guessed.

The earlier code-repo declaration/map experiment is removed. openspec context does not infer implementation repos; users compose code folders explicitly with personal worksets.

Locked Decisions

1. Assembly is a local convenience, not a planning system. The selected OpenSpec root remains the source of truth; references provide read-only upstream context.
2. The primary interface is an agent brief. The editor file is one consumer of the same assembled data.
3. No machinery. No clone, pull, push, sync, branch, worktree, dashboard, launch, or edit-boundary enforcement.
4. Unresolvable references are reported, not guessed.

JSON Shape

{
  "root": { "path": "/abs/root", "source": "store|declared|nearest", "store_id": "...", "role": "openspec_root" },
  "members": [
    { "role": "referenced_store", "id": "upstream-context", "path": "/abs/store", "fetch": "openspec show <spec-id> --type spec --store upstream-context", "status": [] },
    { "role": "referenced_store", "id": "design-system", "status": [{ "code": "reference_unresolved" }] }
  ],
  "status": []
}

Available members have path and empty status. Unavailable members are kept in the brief with their diagnostics and fixes. The top-level status carries cross-cutting degradation such as an unreadable registry.

Human Output

$ openspec context
Working context for team-context (/Users/dev/src/team-context)

OpenSpec root
  team-context  /Users/dev/src/team-context

Referenced stores
  upstream-context  /Users/dev/openspec/upstream-context
    Fetch: openspec show <spec-id> --type spec --store upstream-context

Not available on this machine
  - design-system: not registered
    Fix: git clone -- https://github.com/acme/design-system.git /Users/dev/openspec/design-system && openspec store register '/Users/dev/openspec/design-system' --id design-system

.code-workspace Emission

--code-workspace <path> writes {folders: [{name, path}...]} with the root first, then available referenced stores named ref:<id>. Existing files refuse without --force; missing parent directories fail; JSON mode keeps stdout as a single brief and sends write confirmation to stderr.

Scope

In scope:

• src/core/working-set.ts: pure working-set assembly and workspace JSON builder.
• src/commands/context.ts and src/commands/shared-gather.ts: root relationship data gather, human/JSON output, code-workspace write handling.
• Deletion of old workspace opening machinery.
• Docs and tests for root + referenced-store assembly.

Out of scope:

• Editor integrations beyond .code-workspace; terminal session launchers.
• Any code-repo inference or implementation-folder discovery.
• Per-change context narrowing.

Acceptance Criteria

Assembly From References

• GIVEN a store-backed root with one resolvable and one unresolvable reference
• WHEN openspec context runs in human and JSON modes
• THEN JSON contains the root and referenced-store members only, resolved members carry absolute paths and fetch recipes, unresolved members carry existing diagnostics verbatim, and exit code is 0

Nothing Declared

• GIVEN a root with no references
• WHEN context runs
• THEN the set contains only the root, members: [], and human output says the working set is this root alone

Code-Workspace Emission

• GIVEN the mixed-reference fixture above
• WHEN openspec context --code-workspace out.code-workspace runs
• THEN the file contains folders for the root plus resolved referenced stores only, unresolved members are reported on stderr, overwrite requires --force, and no other files or registry state change

Old Machinery Is Gone

• GIVEN the post-4.1 tree
• WHEN the suite runs and the ledger is read
• THEN old workspace state machinery is gone and assembly works without any workspace or initiative state
