docs: add "what EACS actually does" page (button-press → re-enroll)#46
Merged
Conversation
Adds docs/eacs.html, the missing prequel to the deep dive: what macOS does between the MDM EraseDevice command and the moment a host is re-enrolled, where every relops-bootstrap reprovision begins. Covers the EraseDevice/ObliterationBehavior command and the escrowed Bootstrap Token that gates it, the Secure Enclave cryptographic erase (no reinstall, no image download — hence the sub-5-minute wipe), what survives (SSV/Preboot/Recovery) vs what dies (Data volume + keys), the Setup Assistant → activation → ADE → MDM enrollment sequence, the ordered Apple network traffic + ports, and the MDC1 firewall allowlist. Also the Apple Silicon vs T2 vs pre-T2 split, a macOS 12→26 change timeline, an honest "what we couldn't confirm" section, and cited sources. Scope deliberately stops at enrollment complete; the deep dive picks up there. Wires cross-links from index.html, deep-dive.html, and the README.

What
Adds
docs/eacs.html— "What actually happens when you press Erase All Content and Settings" — the missing prequel to the deep dive. Every relops-bootstrap reprovision begins withEACS wipe → DEP re-enroll, and the deep dive explicitly assumes the host is already enrolled. This page fills that gap and stops the instant enrollment completes (the deep dive picks up from there).Built in the same GitHub-dark theme as the existing docs (same CSS vars, numbered sections, typed callouts, tables, TOC, footer) so it reads as one set.
Contents (11 sections)
EraseDevice/ObliterationBehaviorcommand table, and a danger callout for the escrowed-Bootstrap-Token gate (macOS 12.0.1+) — the load-bearing prerequisite for our reprovision loop, with the two classic failure modes17.0.0.0/8over hand-picked subnets)Cross-links wired
