Product briefing
ArcoreNarrator
ProductionDeveloper Tooling
Deterministic code analysis and review platform where the machine provides evidence and the LLM only narrates. ArcoreNarrator enforces evidence-linked claims, explicit coverage gaps, and citation-linted narratives across a multi-plane pipeline (Miner → Indexer → Auditor → Narrator → Studio).

What changed
May 15, 2026: Added governance-aligned copy, compare tooling support, and transparency notes.
Key Features
- 1Miner for deterministic evidence extraction (diffs, AST spans via tree-sitter)
- 2Indexer builds symbol graphs, dependency edges, routes, and ORM models
- 3Auditor generates claims/findings and coverage metrics with policy rules
- 4Coverage gaps elevated as first-class (no silent failures)
- 5Narrator renders manifests with enforced citations and post-gen linting
- 6Studio tri-pane UI linking code, evidence, and narrative with gap highlights
- 7Plan mode validates feasibility against the actual codebase before claiming coverage

- •**Scopes:** Pipeline triggers, manifest access, and narrative rendering governed by RBAC.
Compliance & Security
Compliance
- ✓Deterministic pipeline outputs with full evidence links
- ✓Coverage gaps surfaced explicitly (no silent failures)
- ✓Evidence stored in object storage; manifests/indexes in PostgreSQL; pipeline queues via Redis/Celery
- ✓Policy-driven findings and audit logs; citation linting rejects uncited text
Security
- ✓TLS 1.3
- ✓AES-256 encryption
