 **Tasks.**
 - **#80** [EPIC] LSP validation gate — real per-stage gate + terminal typecheck replacement. Design finalized in the task body; break into the 5 sub-tasks listed there. Container for the work below.
   - **#310** ✅ LSP diagnostics runner: anchor read on server readiness, not the 750ms timer (kills phantom unresolved-import).
-  - **#311** LSP gate: lint-class diagnostics (unused/deprecated) must not fail the run — classify by `DiagnosticTag`, not severity.

 - **#267** Verify build-gate actually fires + re-scope #40 (LSP obsoletes the typecheck alias) — one live run settles both. Acceptance gate for the whole goal; do last.
 
 **Exit.** One live freestyle run where every write stage gets LSP diagnostics scoped to its write blast-radius, terminal build-gate fires, and a stranded-scaffold case goes to recovery instead of `WorkflowFailed`.

+- **#310 ✅** (commit `a95475be`). `awaitDiagnostics` waits for one push per URI then a *quiescent*
+  period anchored to the last server publication (`awaitAll` + `awaitQuiet`), not a 750ms timer
+  started at `didOpen`. Kills the half-loaded-project phantom unresolved-import.
+- **#311 ✅** (commit `f61864ff`). `LspDiagnostic.tags` (lowercased `DiagnosticTag` names) is carried
+  from LSP4J through the event; `SessionOrchestratorGates2` gates on `severity == error && !isLint`.
+  A `noUnusedLocals` tsconfig promoting TS6133 to *error* no longer hard-fails a run that no rewrite
+  could clear. Lint diagnostics stay recorded and visible, just non-gating. Classification by
+  protocol tag, not a TS-code whitelist. Test: `core/events/.../LspDiagnosticTest.kt`.
+- **#263 ✅** (commit `867e99d1`). Two findings on trace:
+  - The *reported* selection bug was already fixed by `159b3f1e` (#277) — `autoGateStages` is every
+    write-declaring stage **plus** `terminalStageId(plan)`, so a non-writing review terminal is
+    gated and `runExecutionGate` promotes it to PROJECT off the real `FileWritten` manifest. The
+    2026-07-18 evidence was stale.
+  - The hole that remained: any stage declaring `build_expectation: project|tests` zeroed the whole
+    auto-gate set, so a plan building at stage 3 of 9 had nothing verifying the six stages written
+    after it. A declared build now suppresses only the redundant *per-writing-stage* gates; the
+    terminal floor always stays.
+  - Left deliberately: the gate chain still short-circuits before the execution gate when the
+    contract gate fails. The stage fails either way — cheap gates first, no COMPLETE-lie.
+
+**Goal 1 remaining: #267 only** — the acceptance live run. Needs the #191 `setup = "npm ci"` alias
+first, or the now-firing gate fails on absent `node_modules` rather than on real code. Fold the
+unverified #312/#313 trailing-mandate check into the same run.
