# 1CLLMARCH Fact Check And Stabilization Plan

Updated at: 2026-04-11  
Source baseline: `docs/TECH/1CLLMARCH.md`

## 1. Purpose

This document fixes the current factual state of the codebase against `1CLLMARCH` and records a production-focused stabilization plan that preserves:

1. existing MCP routes;
2. manual routing and guard logic;
3. GUI manual markup + autorun operational loop.

## 2. Executive Reality Check

Current state is **not MVP** and also **not stable production**.  
It is an advanced prototype with strong observability and eval tooling, but with architectural coupling and quality bottlenecks.

Approximate readiness against target architecture: **55/100**.

## 3. Verified Facts (Code + Runtime)

1. Strong engineering layers already exist:
   - requirement extraction, coverage, grounding checks;
   - rich debug payload and session trace;
   - investigation state/followup continuity;
   - manual annotation schema and post-analysis queues;
   - async eval run + live history APIs.
2. Main production blockers:
   - orchestration monolith and coupling in `assistantService.ts`;
   - deterministic/template-heavy final answer construction;
   - large lexical heuristic surface for intent routing;
   - temporal policy inconsistency (date handling differs by lane/path);
   - hidden fallback behavior around historical snapshot assumptions.
3. Quality metrics from latest Stage1 runs confirm weak user value:
   - low retrieval differentiation;
   - high generic explanation rate;
   - low accountant actionability;
   - zero mechanism specificity.

## 4. Gap Vs `1CLLMARCH`

### 4.1 Already aligned (partially or strongly)

1. Structured normalization contracts and validator loops.
2. Coverage and grounding artifacts (with different naming than target).
3. Conversation state persistence.
4. Operational diagnostics and report generation.

### 4.2 Not aligned enough for stable prod

1. Role separation (Interpreter/Planner/Critic/Answer) is incomplete and strongly coupled.
2. Final user answer quality is constrained by deterministic template synthesis.
3. Unified contract for analysis date/time scope is missing across all lanes.
4. Result classes from target (`FULLY_ANSWERED`, `BLOCKED_BY_*`, etc.) are not normalized as one contract.
5. Reason-code taxonomy exists but is fragmented across modules.

## 5. Stabilization Plan (No Route Breakage)

## Stage 1 (P0): Unified Analysis Context + Temporal Hardening

Goal:
1. Introduce unified `analysis_context` contract.
2. Propagate it through eval -> assistant -> runtime lanes.
3. Remove hidden hardcoded period fallback in live MCP plan generation.
4. Keep backward compatibility (`period_hint` still supported).

Acceptance:
1. If analysis date is set, runtime uses it explicitly in both deep/address paths.
2. If analysis date is absent, runtime no longer silently injects fixed historical date in live-plan fallback.
3. Existing APIs and manual workflows remain operational.

Implemented in current pass:
1. Added unified `analysis_context` contract to request context (`as_of_date`, `period_from`, `period_to`, `snapshot_mode`, `source`).
2. Added compatibility bridge: legacy `period_hint` is still accepted and normalized into `analysis_context`.
3. Propagated analysis context through eval flows into assistant runtime.
4. Applied analysis context in temporal guard with explicit precedence over implicit snapshot lock.
5. Removed hidden hardcoded live-plan fallback period by switching to:
   - explicit analysis period/date when provided;
   - query-derived period when present;
   - generic live probe when period is absent.

Validation:
1. `npm run build` passed.
2. Targeted runtime tests passed:
   - `assistantMcpRuntimeBridge.test.ts`
   - `assistantAddressFollowupContext.test.ts`

Status: **Completed**

1. Tightened analysis attempt builder normalizers:
   - `assistantDeepTurnAnalysisAttemptInputBuilder.ts`
   - removed `unknown` from anchor/period helpers; now `Partial<CompanyAnchorSet>` + typed primary period.
2. Narrowed response runtime normalization helpers:
   - `assistantDeepTurnResponseRuntimeAdapter.ts`
   - execution plan normalization now consumes typed `AssistantExecutionPlanItem[]`;
   - helper signatures no longer accept `unknown` where input is already typed.
3. Preserved behavior:
   - no runtime logic changes; type alignment only.

Validation:
1. Not run in this pass (type-only changes).

Implemented in current pass (Phase 2.141 + 2.142 + 2.143 + 2.144):
1. Tightened attempt input defaults:
   - `assistantDeepTurnAttemptInputBuilder.ts`
   - response attempt default type is now `AssistantMessageResponsePayload`.
2. Tightened retrieval raw result typing:

   - removed `unknown` from raw result record types.
2. Tightened normalized fragment extraction:
   - `assistantDeepTurnPackaging.ts`
   - normalized fragments now typed to `NormalizedQueryV2*` fragments.
3. Preserved behavior:
   - no runtime logic changes; type alignment only.

Validation:
1. Not run in this pass (type-only changes).

Status: **Completed (Phase 2.1–2.146)**

### Stage 2 Completion Report (Summary)
1. Orchestration monolith decomposed into explicit modules:
   - QueryFrame, ExecutionPlan, EvidenceBundle, Coverage/Grounding, Answer package, Debug payload, Log details.
2. Deep lane now uses stable contracts end-to-end:
   - `assistant_orchestration_contracts_v1`, `assistant_evidence_bundle_v1`, `assistant_coverage_contract_v1`.
3. Audit & trace coverage standardized:
   - temporal/polarity/claim/evidence guards, live-route audits, followup usage, outcome class.
4. Type hardening complete across deep chain:
   - normalized payloads, execution plan, retrieval calls/raw, debug routes, runtime meta, investigation state.
5. Behavior preserved throughout refactor (no route/answer regressions by design).

### Stage 2 Closure Audit (2026-04-11)
1. Fixed runtime-critical context loss in `assistantTurnRuntimeDepsAdapter.ts`:
   - unbound session store/logger/normalizer methods caused `TypeError` at `assistantSessionStore.ensureSession(...)` and mass `500` responses in API tests.
2. Added safe method wrappers in deps adapter:
   - `ensureSession`, `appendItem`, `getSession`, `persistSession`, `setInvestigationState`, `normalize`.
3. Added regression guard:
   - `assistantTurnRuntimeDepsAdapter.test.ts` now includes a stateful instance-context test to prevent `this` loss regressions.
4. Validation gates (fact):
   - `npm run build` passed.
   - Combined Stage 2 regression validation passed: `37` files / `95` tests (deep-turn adapters/builders/packaging, orchestration contracts/runtime, MCP bridge, followup continuity, wave10 corrective regression).
5. Scope note:
   - Full backend suite still has red tests in Stage 3/4 probes and long-running acceptance packs; this is tracked under Stage 3 backlog and is not a Stage 2 blocker.

### Stage 2 Remaining Risks (Known)
1. Final answer quality still template-heavy and brittle.
2. Lexical routing pressure remains high (dictionary overfitting risk).
3. Deterministic guards still compensate for weak semantic parsing.

## Stage 3 (P2): Hybrid Semantic Layer (LLM + Deterministic Guards)

Goal:
1. Use LLM for semantic extraction/decomposition in strict schema.
2. Keep deterministic guardrails as verifier, not primary “brain”.
3. Reduce dictionary overfitting and false route drifts.

Plan (Stage 3):
1. **Schema-first semantic extraction**
   - Strict JSON schema for: entities, time scope, intent, ambiguity, success criteria.
   - Hard validation + retry/repair loop.
2. **LLM decomposition with guardrails**
   - Decomposition produces executable plan candidates.
   - Deterministic guards validate: domain polarity, temporal window, claim-bound anchors.
3. **Evidence-first reasoning**
   - LLM only summarizes from evidence bundle, never invents facts.
4. **Context binding**
   - Carryover only via typed followup state, not free-text memory.
5. **Quality gates**
   - Coverage critic threshold before final answer.
   - Reason-code taxonomy normalized.

Acceptance (Stage 3):
1. LLM outputs strictly validated schema for extraction/decomposition (no free-form).
2. Deterministic guards can block or downgrade answers when evidence insufficient.
3. False route drifts and generic responses reduced in regression packs.
4. Manual markup shows increase in “correct/grounded” labels.

Status: Planned

## Stage 4 (P2): Human-Centric Answer Layer

Goal:
1. Move final user response to contract-driven answer package with:
   - direct answer;
   - what was checked;
   - what was found;
   - what remains unproven;
   - best next step.
2. Keep claim-to-evidence binding strict.

Status: Planned

## Stage 5 (P3): Quality Loop Driven By GUI Markup

Goal:
1. Drive backlog from `manual_case_decision` queues.
2. Build targeted regression packs from real failed comments.
3. Track trend by reason-code clusters.

Status: Planned

## 6. Non-Negotiable Constraints

1. Do not break MCP route interfaces.
2. Do not remove manual logic without compatible replacement.
3. Preserve UTF-8 (without BOM) for all source/doc files.
4. Keep manual markup and autorun API contract stable.
