章节标题：“Description”

On 2026-09-22 the owner, after reading the evaluation bizplan/product/switch/air/evaluations/ti-cc2340-touch-battery.md, wrote "电池考虑 CR2450". Read as a decision, this returns the Air battery to the single CR2450 Li-MnO2 coin cell that the 2026-09-11 decision replaced with 2×AAA Li-FeS2, which in turn requires a first-version SoC that runs from 2.0 V without a boost converter and with ≤11 mA radio peaks; the ESP32-H2 cannot (3.0 V minimum, 0.35 A peak). The change therefore touches the Level 1 spec (battery, thickness, budget, AIR-01, AIR-O-05/06), the design appendix (platform recommendation, diagram, budget, electrical requirements), the brief, the line spec and brief, the package index, the H2 evaluation, the product plan §P5 and the open-questions register.

Acceptance criteria:

  1. Every page that states the Air battery, thickness or budget carries the CR2450 values, and the 2×AAA values survive only in change logs and dated notes.
  2. The design appendix names a first-version SoC whose datasheet supply floor and radio peak are compatible with a CR2450 fed directly, and records why the ESP32-H2 is no longer it.
  3. Requirement and open-item IDs are unchanged; new obligations (child-resistant compartment, coin-cell transport, storage capacitor, low-battery threshold under load) are attached to existing IDs or open items.
  4. bun run docs:lint && bun run docs:build && git diff --check passes.
