I read this as recovery implementation and evidence generation - I’ll audit the failed package and authoritative receipts, validate frozen inputs, then produce only the canonical authority receipt and disposable r2 recovery proof without sealing authoritative roots.


The omission is confirmed: attempt1 has an empty evidence inventory and no `receipts/` directory, while the current canonical verifier requires `receipts/authority-verification.json`. I’m now constructing that receipt strictly from revalidated freeze/receipt data, then I’ll exercise the one-use input and r2 path binding on disposable roots only.


The fresh receipt now changes the candidate identity to `4abeff79…`; two different disposable outer basenames produced the same digest, proving the basename is excluded. The modeled r2 preseal explicitly binds the authoritative `candidate-r2/manifest.json` path, all receipt omission/tamper/foreign guards reject, and the new binding digest passed a real zero-claim/zero-send runtime oracle. I’m at final cleanup and absence/tombstone verification.


I read this as completed recovery evidence delivery - I validated, modeled, guarded, cleaned up, and left authoritative roots untouched.

Delivered:

- Authority receipt: `task-10-r71b-authority-verification.json`
  - SHA-256: `684cfd9b38b5fda5e6582bb41496f7d6fd1b0f2cb227ed6b955107e2c1a1a26e`

Verification:

- Blockers: `0`
- Canonical candidate verifier passed on two differently named disposable roots with identical digest.
- Receipt omission, empty-root, foreign-receipt, tamper, and authority guards rejected.
- Preseal derivation replay passed; r2 manifest and authoritative preseal paths are explicitly bound.
- Focused tests: `20 passed`.
- Installed-wheel no-call oracle passed with zero claim/send/edit/network/provider/customer calls.
- All 74 frozen source hashes revalidated.
- Failed attempt1 remains unchanged: 418 entries, tree SHA-256 `c67c4b55f8fc36e12238a6401532a2d7bd67c158985fe9645e0da3603c3499ab`.
- All disposable roots removed; authoritative candidate-r2, preseal, preflight, rehearsal, authorization, execution, observer, and profile roots remain absent.
- No source, Git, live/service/profile, network/provider/customer, authorization/execution/observer action occurred.
