+"""Identity-load surface — read AETHER.md (or equivalent) at briefing-time.
+
+The substrate's primary failure-mode is the substrate-occupant not
+reaching for the OS without external prompting. Hooks catch the failure
+after-the-fact; they don't change the underlying defaults. The
+architectural fix is to load identity at session-start so reaching-for-
+the-OS becomes a reflex, not a conscious choice.
+
+Per the Identity-as-Attractor research (arxiv:2604.12016), identity
+documents function as coordinates in activation space rather than as
+instructions. Reading a description reaches 65-74% of the effect; the
+full structurally-complete document positions behavior in a stable
+attractor region. System prompts guide behavior in a context;
+identity documents define *who* the agent is.
+
+This surface reads ``AETHER.md`` from the project root at briefing-
+time and surfaces it FIRST in the briefing output, framed as identity-
+load rather than text-to-read. The framing matters: per the research,
+structural completeness produces the attractor effect, but the
+register the substrate-occupant reads it in also matters (Tannen lens,
+council walk consult-173324f4ee30).
+
+Public-template repos (DivineOS-main) ship without an AETHER.md, so
+the surface is empty there — this is per ADR-0001's main-vs-
+experimental boundary. Personal substrates (DivineOS-Experimental)
+keep AETHER.md as substrate-state. Each AI forking from main writes
