Comprehensive survey of every pack in the tree across five layers
(primitives → language → teaching → policy → selection axes → style)
with per-pack stats, cross-pack lemma overlap, teaching-chain graph
topology, and a ranked top-leverage-gaps list.
Key findings:
* **Layer 4 (selection axes) is the densest by far** — 24 packs
(17 anchor lenses + 7 registers). Greek and Hebrew lens
families are at parity (8 each).
* **Layer 2 (teaching corpora) is the load-bearing thin layer** —
only 41 reviewed chains across 18 subjects, with just 2 intent
shapes covered (CAUSE / VERIFICATION) and 7 connectives total.
No COMPARISON / PROCEDURE / CORRECTION chains exist; those
intents route through pack composers only.
* **Layer 1 EN is solid** — 354 lemmas across 12 mounted packs
with 93% gloss coverage; 24 ungloss'd lemmas remain.
* **Cross-language is structurally present but content-light** —
grc / he micro-packs ship and mount; the bigger
``*_cognition_v1`` siblings ratify but are not in the default
mount; no glosses exist on any non-EN pack.
* **Three drafted ethics packs are unratified** (legal /
research / engineering) — the highest-leverage low-effort gap.
* **Rhetorical-style axis ships substrate only** — one
null-lift pack; ADR-0087 consumer phase pending.
Top-leverage gaps ordered by ratio of unblocked value to effort
are enumerated in §7 of the doc itself. No code lands here.
