docs: README label refresh + per-module reference + Graphviz diagrams
Three things in one commit because they're tightly coupled (README
points at the diagrams; diagrams index in modules/index.md points
back at README; module pages embed the diagrams).
(1) README — label refresh:
- Quickstart label changed from STRICT/HYBRID/UNGROUNDED to the
four-rung ladder POINTER-LINKED → ANCHOR-WARRANTED →
EVIDENCE-WARRANTED → UNGROUNDED with -PARTIAL suffix on HYBRID.
- Verifier section spells out both layers (schema trichotomy +
display ladder), the seven hard checks of claim_lattice, and
the five anchor classes of warrant.
- Architecture tree updated: concepts/ package added, qa/
sub-modules expanded (warrant, evidence, parse_claims, dag),
verify.py described as quote/span/entity/paraphrase + claim_lattice.
- Concept overlay description updated for corpus-derived layer
(concept_relations table, link_reciprocity extractor, 1.6%
tax cite).
- Test count: 326+ → 641+.
(2) docs/diagrams/ — Graphviz dot sources:
- aborist-modules.dot — top-level package graph (substrate /
storage / sources / retrieval / qa / mesh / cli)
- query-pipeline.dot — question → cache → retrieval → LLM →
verify → render → cache write, with phase budgets
- ingest-pipeline.dot — source doc → canonicalize → chunk →
Merkle → upsert (+ optional distill)
- verifier-ladder.dot — (audit_mode, violations) → display rung
decision tree
Existing mesh-*.dot kept as-is. Makefile `make docs` target
extended to also emit .svg alongside the existing .png so the
diagrams render in markdown viewers.
(3) docs/modules/ — per-module reference pages:
- index.md (links to every diagram + every module page)
- merkle.md, document.md, store.md, ingest.md, evict.md,
sources.md, search.md, concepts.md, qa.md, distill.md,
wikitext.md
Each page is a one-screenful concise reference: what the
module is for, public API, key invariants, embedded diagrams
where useful, link to source. Mesh stays at the existing
docs/mesh.md + docs/mesh-deploy.md (already comprehensive).
Tests: 641 passed (no code change).
