feat(orchestration): escalate repeated scope/manifest write-block to user approval (#301)

Small models frequently fail to comply with the WRITE_SCOPE/PATH_OUTSIDE_MANIFEST
remediation ("add its path via task_update affected_paths") and instead thrash the
same out-of-scope write call turn after turn, burning the session without ever
completing. After `tuning.escalateScopeAfterN` (default 3) consecutive rejections
of the SAME path for a scope/manifest reason, the orchestrator now reaches back to
the FIRST rejected invocation of that path (its pristine, pre-degraded arguments),
and routes it through the existing approval/pause flow instead of rejecting again.
On approval, a new WriteScopeGrantedEvent widens the effective write manifest for
that path for the rest of the session (mirroring how OutsidePathAccessGrantedEvent
already widens out-of-workspace reads) and the first attempt's write is executed.
On denial, the call is rejected as before. escalateScopeAfterN = 0 preserves the
old hard-block-forever behavior.

-## 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.

-### #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.

-### #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.

-### #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.

 - Config is read from disk; it is not event-sourced. Do not add event/state/reducer structures here.
 - `ConfigHolder` is the shared mutable reference injected into consumers. Never read the file directly in domain code — always go through `ConfigHolder`.
 - `CorrexConfigWriter` regenerates TOML from the in-memory model; round-tripping loses comments by design.
-- `[git]` is opt-in server transport configuration (`enabled`, `remote`, `base_branch`, optional `author`); it is off by default.
-- `[orchestration].review_loop_max_cycles` bounds review→rework cycles before recovery escalation; default `3`.
-- `ModelConfig.contextSize` defaults to 24,576 tokens; explicit `context_size` remains the operator override for smaller local-model windows.

 - Domain event files: `ApprovalEvents`, `ArtifactEvents`, `ContextEvents`, `InferenceEvents`, `OrchestrationEvents`, `RouterEvents`, `SessionEvents`, `TaskEvents`, `ToolEvents`, `IntentEvents`, `RiskAssessedEvent`, `JournalCompactedEvent`, and many more — all payload definitions live here.
-- `LspDiagnosticsCompletedEvent` records pulled language-server diagnostics or a graceful skip reason; replay consumes this observation and never contacts the server.
 - Shared vocabulary: `IdentityTypes` (SessionId, TaskId, etc.), `Tier`, `TokenUsage`, `ToolReceipt`, `ToolRequest`, `RiskLevel`, `RetryPolicy`, `GrantScope`, `GrantLedger`.

 - **SILENT FAILURE TRAP**: After adding any `EventPayload` subclass, immediately add it to `Serialization.kt` `eventModule` block. Run `./gradlew check` to verify. Tests may pass without it but runtime replay will fail silently.
 - `AnyMapSerializer` — custom serializer for `Map<String, Any?>`; use it for dynamic payloads, don't roll another.
 - Event classes are `@Serializable data class` with no mutable state. No methods beyond data accessors.
-- `RunBranchPushedEvent` records an optional server Git transport push only after it succeeds; its branch/base/head SHAs are observations, not values replay recalculates.
-- `RepoMapEntry.descriptor` is a bounded source-purpose observation recorded with the repo map and used when constructing semantic L3 embeddings.
 - Do not add domain logic to events. They are records, not actors.
 - `EgressAllowlistProjection` — special projection kept in this module because it is used by both `core:toolintent` and `core:events` consumers; it is a shared cross-cutting projection.

 - `SubagentRunner` / `InSessionSubagentRunner` — runs sub-agent invocations within an active session.
 - `StaticAnalysisRunner` / `ProcessStaticAnalysisRunner` — runs static analysis tools and records results as events.
-- `LspDiagnosticsRunner` — injected pull-diagnostics seam; diagnostics are filtered to stage-written files, recorded, and enforced before build/review.
-- Review→rework loops use the configured three-cycle default, then route accumulated notes to recovery once and fail if the fixed DoD still cannot be approved.
 - `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.
-- Every stage receives a small curated operating-guidance system entry: verify observed state, create required project setup, and resolve necessary scope edges without re-deliberating.
