 # gstack inventory: every part, its load per run and its evidence
 
-Generated by `bin/gstack-inventory` from [evidence.json](inventory/evidence.json), the hand-kept ledger, and lib/context-bill.ts. Measured at commit dc218faa6 (2026-11-02). This is a dated snapshot: rerun `bin/gstack-inventory` to refresh it; `bin/gstack-inventory --check` validates the ledger. The rule: [ETHOS.md: 9. Earn Its Place](../ETHOS.md#9-earn-its-place).
