chore: sprint handoffs + Lsp4j runner live-proof

Add per-agent sprint handoff docs (Sonnet/Codex/opencode) mapping the
1-week sprint's two goals to concrete Vikunja tasks. Kept in repo root
(docs/ is gitignored). Includes hanging Lsp4jDiagnosticsRunner change +
its live-proof test.

 - AGENTS.md files are binding work contracts for their subtrees

+## Project Architecture
+
+- Correx is a local-first, event-sourced orchestration kernel for LLM workflows, built with Kotlin/JVM 21 and Gradle.
+- The event log is the sole source of truth. State is rebuilt from events; projections are disposable and owned by their bounded context.
+- Keep deterministic core logic separate from nondeterministic inputs: LLM and tool outputs are untrusted proposals until validation; policy denials are terminal and cannot be overridden.
+- Record each nondeterministic environment observation (for example filesystem, network, retrieval, or clock data) as an event when observed. Replay and downstream logic must use recorded facts and make no external calls.
+- Tools must declare an execution tier and record every side effect as events. Compression and other derived representations are non-authoritative and cannot replace original events.
+- New `EventPayload` implementations must be registered in `core/events/.../serialization/Serialization.kt` in the `eventModule` polymorphic block; otherwise runtime deserialization can fail silently.
+
+## Module Boundaries
+
+- `core/` contains domain logic and may not depend on `infrastructure/` or `apps/`.
+- `infrastructure/` implements adapters against core contracts; `apps/` composes core and infrastructure into runnable processes.
+- Do not introduce circular dependencies or dependencies from a module to a sibling core module unless the module architecture explicitly establishes one. Shared event vocabulary belongs in `core:events`.
+- Inject dependencies rather than constructing concrete collaborators inside domain classes; use existing interfaces at boundaries.
+
+## Kotlin Work Guidance
+
+- Keep reducers limited to deterministic state transitions; do not put domain decisions or side effects in reducers.
+- Convert exceptions to sealed domain results at the earliest practical boundary. Do not use broad `try`/`catch` that silently returns a fallback.
+- Use coroutine-safe patterns: put blocking I/O in `Dispatchers.IO`, never use `Thread.sleep()`, and do not swallow `CancellationException`.
+- Before finalizing a Kotlin file, remove unused imports and verify direct imports only.
+
+## Verification and Context
+
+- Tests for production modules may live under `testing/`; search there before deciding a module has no tests.
+- Run focused tests with `./gradlew :path:to:module:test --rerun-tasks`. Run `./gradlew check` for the full test, Detekt, and Kover verification suite.
+- Detekt failures are enforced. Prefer correcting violations; use the narrowest suppression only for a genuine false positive.
+- Use `python scripts/ctx.py <query>` for ranked code context and `python scripts/ctx.py --deps <file>` for symbol dependency context when relevant.
+
+## Task Tracking
+
+- Use the Vikunja **Correx** project (`project_id: 4`) as the cross-session, user-visible backlog for follow-up work the user wants retained, such as deferred fixes, unverified QA gates, and designed-but-unimplemented work.
+- Use the available Vikunja integration to review, create, and close tasks. Keep each task self-contained with its root cause, chosen fix, and relevant file paths so it can be resumed without prior session context.

+
+## Tasks
+
+### #266 — Retire `pm.repoRoot()`, unify session workspace-root to ONE source
+The workspace root is plumbed through THREE sources that can diverge (boot-static `ProjectMemoryService.repoRoot()`, per-session `boundWorkspace?.workspaceRoot`, `sessionConfig.workspace?.workspaceRoot`). A stopgap already made `sessionWorkspaceRoot(sessionId)` read the bound value; this task RETIRES the vestigial boot root.
+Collapse to canonical `boundWorkspace?.workspaceRoot` (invariant #9, replay-safe). ⚠️ The shared L3 namespace `project:<repoRoot>` is used by ProjectMemoryService AND ArchitectContradictionChecker AND the concept compiler — all must switch together or memory keys drift.
+Pointers: `ServerModule.kt`, `memory/ProjectMemoryService.kt`, `BootWorkspace.kt`, `Main.kt`, `workspace/WorkspaceResolver.kt`, `git/GitRunBranchTransport.kt`.
+**Do this before #189.**
+
+### #189 — Server repo-map scan uses cwd, not session workspace_root
+Symptom of the same #266 divergence (`repoRoot()` vs `bindWorkspace`). Read #266 first — its canonical-root fix may absorb this. **Confirm #189 still needs its own change after #266 lands**; if not, close it referencing #266.
+
+### #191 — Resolve/validate generated manifest dependencies before plan lock or scaffold accept
+A scaffolded manifest (e.g. package.json) needs its deps resolvable / a `setup` step (`npm ci`) before the build gate can pass — otherwise the gate fires into absent `node_modules`.
+**Land this EARLY** — Sonnet's #263/#267 live run depends on it going green.
+
+### #264 — Review loop can't converge
+The review loop loops back `changes_requested` indefinitely with scope drift. Bound iterations + anchor the reviewer to the fixed DoD so it can't keep expanding scope. Kill the drift.
+
+### #40 — Build-gate: toolchain-aware command resolution
+A flat command alias can't serve two toolchains (e.g. npm vs gradle). Resolve build commands per detected toolchain. Related to #263 (the build gate) and #191.

+## Tasks
+
+### #295 — TUI: token usage display for router/talkie (like narrator)
+The narrator already shows token usage in the TUI. Mirror the same display for the router and talkie streams. Follow the existing narrator pattern — don't invent a new widget.
+
+### #296 — TUI: execution plan viewer (freestyle sessions + general)
+Add a view that renders the session's execution plan (stages/transitions) in the TUI. Useful for freestyle runs especially. Reuse whatever plan data already comes over the WS.
+
+### #298 — TUI output view: show CoT/reasoning on artifact + tool-call turns
+The reasoning/CoT stream is already captured (reasoningArtifactId on InferenceCompleted). Surface it in the output view on artifact and tool-call turns so the operator can see the model's reasoning.
+
+### #265 — TUI clarification modal not dismissed when answered externally
+When a clarification is resolved on the server (or answered outside the TUI), the modal stays open. Dismiss it on the server-resolve / external-answer signal. Contained bug — find the modal state and the resolve message.

+## Tasks
+
+### #299 — Single provider death → unrecoverable session kill
+A retryable provider connection drop collapses into a hard `NoEligibleProvider` abort that fails the WHOLE session.
+On a retryable inference failure, tolerate a briefly-absent provider (bounded wait/backoff for the capability) before declaring terminal. Distinguish "provider temporarily down" from "capability never configured".
+Files: `CapabilityAwareRoutingStrategy.kt:31`, `DefaultInferenceRouter.kt:54`, `ServerModule.runSession` (the catch that fails the session), SessionOrchestrator retry path.
+
+### #300 — HealthMonitor detects provider loss ~18s too late
+Same incident as #299. Health status must GATE routing/retry, not just log reactively. Mark a provider unhealthy immediately on the connection drop (event-driven), and have the retry consult health + wait for recovery.
+**Do #299 first — #300 completes the health-gating half.**
+
+### #297 — Analyst CoT indecision loop burns full budget, emits nothing
+Analyst maxed 16384 reasoning tokens and emitted an empty artifact because the request maps to a PARENT epic, not a single task, and the DoD prompt says "the single task this run owns" → endless oscillation.
+Primary fix: pre-resolve which task the run owns before the analyst, OR make the DoD prompt explicit ("define the DoD for the epic as a whole; do NOT pick a child"). Optional backstop (can be a separate task): reasoning-token soft cap.
+
+### #263 + #267 — Auto build-gate never fires on real freestyle scaffold
+The terminal build gate produced ZERO `StaticAnalysisCompleted` events across a 60-file run. Root cause traced in the ticket: writes-based terminal-stage selection can't pick a non-writing REVIEW terminal stage, and the last writing stage's build gate is shadowed by its own contract gate short-circuiting.
+Fix direction: attach the auto build-gate to the last WRITING stage, or run it as a workflow-terminal check on the `done` transition independent of per-stage autoBuildGate. Reconcile code (per-stage writes filter) vs comment (terminal-only) — they disagree today.
+**#267 is the settle-it-live half: one live run confirms the gate fires. Do them together.**
+**Depends on #191 (Codex) landing** — the gate fires into missing `node_modules` without `setup=npm ci`. Coordinate so your live run goes green.
+
+### #301 — Escalate repeated scope/manifest write-block to user approval (Goal 2)
+After N same-path scope/manifest rejections (config `escalate_scope_after_n`, default 3), stop rejecting: reach back to the FIRST rejected invocation's pristine write args in the event log, present via the existing approval/pause flow, approve→widen scope + execute, reject→continue. No branching/replay-engine — plain forward event-log read.
+Wiring pointers in the ticket: `SessionOrchestratorToolExec.kt` ~234-282 (BLOCK branch) and ~284-422 (existing approval flow + `OutsidePathAccessGrantedEvent` widen-and-execute template).
+**This is the natural carry-over if the lane is over-full — it's a feature, not a run-killer.**
+
+## Sequencing
+299 → 300 (same owner). 263/267 needs 191 (Codex) landed first.

+- Optional `[git]` transport creates `run/<sessionId>` from a server-local checkout and pushes it at terminal state; clients review with ordinary Git and never supply a remote URL as `cwd`.
+- Repo-map L3 embeddings use bounded, recorded source descriptors (module/package, imports, leading purpose comment, symbols); raw file bodies are never embedded. Their versioned `repomap:v2` namespace forces a one-time re-embed when the semantic document format changes.
+- At boot, `tools.workspace_root` is the authoritative tool jail and project-observation root. A configured `tools.working_dir` may only remain distinct when it is contained by that root; an outside value is clamped to `workspace_root`.

 - `SubagentRunner` / `InSessionSubagentRunner` — runs sub-agent invocations within an active session.
 - `StaticAnalysisRunner` / `ProcessStaticAnalysisRunner` — runs static analysis tools and records results as events.

 - `StageCheckpointReconciler` — reconciles checkpoint state across stage transitions.
+- Capability-gated failures first retry in place when the stage holds the required tool; an unchanged-fingerprint gate-budget exhaustion routes to the recovery/intent-holder stage when one is available, so capability possession alone cannot cause a frozen owner loop to fail the workflow.
+- Three repeated `REFERENCE_EXISTS` blocks for the same build prerequisite within one stage become a `workspace_precondition` gate failure, which is eligible for file-write recovery rather than remaining disconnected tool-call noise.
