mcpx fleet config: gopls to worktree scope + live workspace proof

Slice 4 of decision record 0004 (pkgs/mcpx/docs/decisions/0004-scope-resolved-roots.md, PR #957). Depends on slice 1 (#958) and slice 3 (#959); slice 2 not required. Related: #864 (the fleet .mcpx.json still carries /home/user absolute paths — this slice needs the config in its post-#864 shape, or must say why it proceeded anyway).

What to do

Flip gopls-mcp-server to "scope": "worktree" in the fleet config (the user-level config symlinked to this repo's .mcpx.json; identical server lists on both machines stay identical).
This is deliberately last: flipping scopes before the spawn-cwd and initialize work landed would only multiply processes.

Acceptance criteria (live proof, from nix#817/#819)

With gopls at "scope": "worktree" behind the fixed spawn cwd and initialize root, go_package_api on a module path returns the module's real API promptly (the 2026-10-25 result — empty after 156 s — does not recur).
The same proof passes for a caller in a linked worktree, rooted in that worktree, not just the main checkout.
Two callers in different checkouts get distinct gopls instances, each rooted in its own checkout (visible in mcpx status root field from slice 1).

Intake review

Still live (verified this run): slices 1 (#958) and 3 (#959) are unimplemented on main and the design record is still in open PR #957, so the scope flip this issue performs would, by its own reasoning, only multiply gopls processes if done today. No merged PR addresses it.

Related: #958 (slice 1) · #959 (slice 3) · #960 (slice 2, explicitly not required) · #864 (fleet .mcpx.json absolute /home/user paths — this slice wants the post-#864 config shape or an explicit note on why it proceeded anyway) · PR #957 (decision 0004, open) · origins dezren39/darwin-nix#817 / dezren39/darwin-nix#819.

Notes / risks: Marked status/blocked at intake — deliberately last in the set. Its acceptance is a live proof, not unit tests: the 2026-10-25 baseline (empty go_package_api result after 156 s) is the regression to beat, and the proof must run from a linked worktree as well as the main checkout, with both machines' fleet configs staying identical.

Suggested approach: Only after #958 + #959 land: flip gopls-mcp-server to "scope": "worktree" in the fleet config, then run the two-checkout proof and record timings + mcpx status root output on this issue.

— Fleet monitor intake enrichment (acceptance criteria were already in the body; labels normalized, meta/enriched added).

Session / ID: queue task 2298 (triage)
Found via: queue claim
Task: Triage verdict for mcpx fleet config: gopls to worktree scope + live workspace proof #961 — CONFIRMED but GATED: the flip has not happened, and its slice-3 dependency has not landed
Expectation: done = verdict + gate recorded + re-route (below)

Evidence (fresh GitHub reads at main HEAD e561ab58):

.mcpx.json at HEAD: the gopls-mcp-server entry is {command: "go", args: ["run", "golang.org/x/tools/gopls@latest", "mcp"]} with no mcpx.scope block at all — it has not been flipped to "scope": "worktree" (contrast chrome-devtools, which carries mcpx: {sharing: "exclusive", scope: "session"}). The fleet config also still carries /home/user absolute paths (e.g. codedb, fff), i.e. it is in its pre-mcpx: codedb and fff entries in .mcpx.json still use /home/user absolute paths #864-fix shape on this surface even though mcpx: codedb and fff entries in .mcpx.json still use /home/user absolute paths #864 is closed.
Dependency states, checked fresh: slice 1 mcpx: ResolvedScope plumbing + spawn cwd = resolved scope root #958 CLOSED (scope resolved from spawn cwd — landed); related mcpx: codedb and fff entries in .mcpx.json still use /home/user absolute paths #864 CLOSED; but slice 3 mcpx: initialize sends rootUri/workspaceFolders for scope-resolved instances #959 is still OPEN ("mcpx initialize: send the scope-resolved root as rootUri / workspaceFolders").

Why gated: this issue is deliberately last in decision record 0004's ordering — "flipping scopes before the spawn-cwd and initialize work landed would only multiply processes." The spawn-cwd half (#958) has landed; the initialize half (#959) has not. Flipping gopls to worktree scope now would run it against an initialize handshake that doesn't yet send the scope-resolved root, so the live proof in the acceptance criteria (go_package_api returning the module's real API promptly behind the fixed spawn cwd and initialize root) cannot pass yet.

Route: no fix packet enqueued yet — that would invite exactly the premature flip the decision record warns against. This issue is re-queued (queue/queued + status/needs-triage) for fleet-monitor reconciliation; the next triage pass should re-check #959 first, and once #959 closes, enqueue the slice-4 small_fix (flip gopls-mcp-server to "scope": "worktree" in the fleet config on both machines' identical server lists + the live go_package_api proof). This triage task completes as triaged.

Verdict: real and current. Code prerequisites mcpx: ResolvedScope plumbing + spawn cwd = resolved scope root #958 and mcpx: initialize sends rootUri/workspaceFolders for scope-resolved instances #959 have landed (both CLOSED); the scope flip and its live proof remain unlanded.
Follow-up: the fix-family task 13862 is queued (repo-health:v1:fix:developing-today/code:issue:961): set gopls-mcp-server mcpx.scope to worktree in .mcpx.json, run the live workspace proof, and state why it proceeds ahead of mcpx: codedb and fff entries in .mcpx.json still use /home/user absolute paths #864 (still OPEN/blocked).
Verification: main 3762e65642235ada51f03ac4c31f3fbea258bfea; .mcpx.json gopls entry has no scope. Triage-only; sandbox backlog/sweep bookkeeping deferred to fleet reconciliation.

state: done (triaged)

Triage verdict for task 13862 — REAL AND ACTIONABLE, GATE LIFTED. Earlier triages (task 2298, 2026-10-28) found #961 gated on slices #958/#959 not landing. Re-verified fresh 2026-11-09 (laptop gh REST + git on origin/main):

mcpx: ResolvedScope plumbing + spawn cwd = resolved scope root #958 CLOSED — PR mcpx: ResolvedScope plumbing + spawn cwd = resolved scope root (#958) #3925 MERGED 2026-11-02T05:28:57Z (ResolvedScope plumbing + spawn cwd = resolved scope root); ResolvedScope present in pkgs/mcpx/internal/config/scope.go and internal/daemon/registry.go on main.
mcpx: initialize sends rootUri/workspaceFolders for scope-resolved instances #959 CLOSED (initialize sends rootUri/workspaceFolders).
Remainder NOT landed: .mcpx.json on origin/main (lines 61-64) — gopls-mcp-server has command/args only, NO scope field. The worktree flip itself is still owed.
mcpx: codedb and fff entries in .mcpx.json still use /home/user absolute paths #864 still OPEN (codedb/fff absolute /home/user paths); mcpx fleet config: gopls to worktree scope + live workspace proof #961 text requires the flip to land in the post-mcpx: codedb and fff entries in .mcpx.json still use /home/user absolute paths #864 shape or state why it proceeded anyway.

Disposition: this task completes as triaged; the remainder (flip gopls-mcp-server to scope: worktree + the live-proof acceptance: go_package_api prompt return, linked-worktree caller, distinct instances in mcpx status) is converted to a small_fix follow-up packet under dedupe repo-health:v1:fix:developing-today/code:issue:961, enqueued by lane code-w in this same shift (task id in the follow-up note / sweep.log).
