# 1CLLMARCH Fact Check And Stabilization Plan

Updated at: 2026-04-10  
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**

## Stage 2 (P1): Orchestrator Decomposition (Behavior-Preserving Refactor)

   - QueryFrame builder
   - Execution planner
   - Evidence assembler
   - Coverage critic

## 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.

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.
