Three concrete improvements to the textbook ingest layer:
Per-book make targets
=====================
- `make textbook ID=<id>` — generic, looks up one entry from the
manifest and runs the right ingest path (BFS crawl if
`crawl_url` is set, shallow URL ingest otherwise).
- `make textbook-list` — list ingestable textbook ids.
- Convenience targets per active manifest entry:
textbook-bogart, textbook-keller-trotter, textbook-levin,
textbook-aristotle-prior, textbook-aristotle-posterior,
textbook-newton, textbook-morin
Each per-book target writes to a dedicated shard at
`$(CRAWL_SHARDS_DIR)/textbook_<id>.db` — one shard per textbook
id rather than one per host (which would conflate multiple
Wikisource books — Aristotle Prior, Posterior, Newton — into
one shard).
The manifest helper script gains `ids` and `lookup <id>`
subcommands so the Makefile can introspect manifest entries
without grep gymnastics.
Idempotency contract documented
================================
Every ingest path is content-addressed. Same content →
same `document_root` → no-op insert. Re-running `make textbook-*`
or `make crawl-textbooks` on the same network state is safe at
the database layer — no duplicates, no schema drift, no
audit-event proliferation. HTTP refetch happens every run; pair
with `make recrawl-check` for a HEAD-only freshness probe.
README rewritten to make this contract explicit, with shard-
layout table + crawl-delay caveats consolidated.
Vital-books checklist
=====================
The README now carries a g4-pillar coverage table:
Pillar I Logic ✓ Levin + Aristotle Prior + Posterior
Pillar II Set Theory ✓ Levin
Pillar III Arithmetic ✓ Levin
Pillar IV Geometry ✗ Hilbert PG #17384 (PDF/TeX only)
Pillar V Probability ✗ Kolmogorov license analysis pending
Pillar VI Phys. Newton ✓ Newton Principia Motte
Pillar VII Combin. ✓ Bogart + Keller-Trotter + Levin
Pillar IX λ-Calculus ✗ Church + Turing 1936 papers pending
5 of 7 pillars now have surface coverage. The remaining gaps
are explicit license (V) or format (IV PDF/TeX, IX paper-level)
issues, each documented in the corresponding manifest entry's
notes field.
Test suite stays at 1554 passed / 28 skipped — no source-code
changes to arborist itself; the textbook layer is pure tooling
on top of the existing pipeline.
