Conversation
Re-cuts the LTC (+DOGE aux) crossing soak-harness so it lands the moment the swarm (VM119/120/121) has a target, per integrator UID2071. Mirrors the dgb/dash G2 harnesses but THREE-TIER per operator 2026-07-03 wire-compat: T-A jtoomim v35-only (raw-tx) T-B p2pool-merged-v36 (python, v36 dest) T-C c2pool-ltc (C++, AutoRatchet, DOGE aux embedded) -- on ONE sharechain. Staged with the 3301 accept-floor (params.hpp:65), the PR#95 8-byte identifier (e037d5b8c6923410), and --fresh-ratchet (archives prior ratchet state, never destroys). Staging: forward natural-fill -> ratchet cross (.37/.38/.39 repoint) -> reverse. 5 checks: three-tier cohabit, vote-visibility (zero v36-byte leak into v35 shares), #288 staged accept gate, ratchet+persist+reverse, byte-compat differential. Found gap recorded in-script: LTC lacks the dgb/btc AutoRatchet sim/tail-guard/ desired-version KATs its own state machine is the reference for; --sim-votes rows are [GATED: ltc-ratchet-kats] until those ports land (next milestone). Rig rows GATED until start-tap frees R1-LTC onto the v36 tier. Deploy-only; natural- vote hard gate preserved; never force-activates.
…erged-aux) Standalone host-compilable harness proving FOUND->ASSEMBLED->ACCEPTED is regime-independent (v35/HYBRID/v36) for BOTH the LTC parent block and the DOGE aux block it carries. Asserts: - populated assembly: 6 diverse tx (coinbase/P2PKH/P2SH/segwit/MWEB/aux-cb), never coinbase-only, identical across regimes; - LTC dual sink (submit_block_p2p -> submitblock RPC fallback); - DOGE aux dual sink (embedded P2P relay -> submitauxblock->dogecoind); - merged-mining coupling: aux LOST when parent LOST, aux sinks notwithstanding; - load-bearing invariant regime _|_ reaches_network on BOTH chains. Confined to src/impl/ltc/test; reads core::version_gate SSOT read-only, no core/bitcoin_family drift. Off the CI allowlist (no #137 trap) until the G3 regtest VM lane is authorized; live leg swaps the sink lambdas for the real submit paths.

…ent + DOGE aux) (#870) * ltc/doge: G3a populated-block-production CI gate (non-hollow, LTC parent + DOGE aux) Wire PR #679 g3a_populated_block_regtest_test.cpp (previously an unbuilt standalone main(), dead to CI) into CMake as the ctest target LtcG3aPopulated, add a machine-parseable G3A_ASSERTIONS_PASSED summary, and add the DASH/BCH-modeled gate script tests/gates/ltc_g3a_regtest_block_production.sh: network-free CI arm via ctest with an empty-suite guard + an assertion-count floor (>=38), plus an opt-in live regtest arm gated on LTC_RPC_PASS+DOGE_RPC_PASS (deterministic skip absent creds). Populated LTC parent (coinbase+P2PKH+P2SH+segwit+MWEB) carries the DOGE aux-coinbase auxpow child; production path proven regime-independent (v35/ HYBRID/v36) on both the LTC parent and DOGE aux dual sinks. * ci: install LTC G3a populated-regtest gate workflow + allowlist ltc_g3a_populated_test Workflow files cannot be pushed over the API token (no workflow scope), so they land here via the SSH remote. Also fixes the drift-guard failure on this branch: ltc_g3a_populated_test is declared in src/impl/ltc/test/CMakeLists.txt but was absent from the build.yml --target allowlist in both the linux and linux-asan jobs (NOT_BUILT risk). --------- Co-authored-by: frstrtr <frstrtr@users.noreply.github.com>
