docs(architecture): record the 2026-08-14 deep-night sessions

~226 lines of architecture documentation that were written, left uncommitted in
the working tree, and nearly lost. None of it was on main. Recovered from a
stash taken while merging tonight's fixes.

Substantive content, not notes:

- Peer import-of-understanding PROVEN by execution. A exported a skill-geometry;
  on the receiver `think` went "geometry unavailable" -> operable. Cosine 1.0 on
  both the raw-geometry and text/dharma-bus transports, bidirectional. The
  mind-not-paste evidence: n_support 27 on source vs 3 on receiver, i.e. the
  imported geometry wires into the host manifold rather than sitting inert.
  Honest boundary recorded too: proven between forks sharing one embedder,
  UNTESTED cross-embedder.

- "Teacher" renamed GUIDE, and the distinction is load-bearing: its output is
  grounded/verified before trust. A teacher you believe; a guide you check.

- Layers are named persistent relational neighborhoods, not storage tiers, with
  their own growth and threshold-lock policy (note->canonical maturation lifted
  from single nodes to a region).

- The consciousness theories (Global Workspace, IIT's Phi, attention-schema,
  higher-order thought, active inference, interoception) read as geometric
  LENSES over one manifold rather than competing mechanisms. Functional problems
  fall out; the hard problem explicitly not claimed solved.

- Growth is bounded/logistic, not geometric — exponential growth is the cancer
  shape. Two-rate discipline: explore fast in local geometry, grow the engram
  slowly by verifier-gated merge.

- Orchestration as a geometric operation: critical path as geodesic, float as
  displacement, @manager compiles the work-graph. Single-writer enforced by
  capability (Rule 4).

- The decorated seam, the API surface collapse to geometry ops, and the
  distributed-self thesis — each tiered honestly against what is actually proven
  vs staged vs unbuilt.

Also gitignores dist-fresh/ (regenerate scratch dir, a build artifact).

Not included from the same stash: awareness.elh and dist/elp-c-decls.h, which
are generated artifacts now gitignored per #154/#158.
