+# DASH Greenlight Gate G2 — RATCHET Staged-Migration — Evidence
+
+Gate sequence: G1 (version_gate SSOT boundary KAT) → **G2 (this)** → G3a/G3b (regtest block production, **already PROVEN**: populated won blocks crossed + submitblock-accepted on regtest).
+Harness: `scripts/dash_g2_ratchet_staged_migration_harness.sh` (mirrors DGB #427 / BTC #436).
+Oracle (conformance reference): `frstrtr/p2pool-dash @9a0a609` — sharechain share **VERSION=16** (NOT v35).
+c2pool-dash drives the **16 → 36 ratchet**, backward-compatible with the v16 oracle during the migration window. This is the DASH per-coin migration gate against its OWN oracle — a **separate X11 sharechain**, NOT the LTC v35 crossing (DASH is UNFENCED from the LTC soak; never gated on it).
+
+## Testbed (self-provisioned, isolated — bucket-1 isolation primitives kept per-instance)
+| Field | Value |
+|---|---|
+| Net | isolated **dashd regtest** (DASH **has** a `--regtest` parent — same substrate as the G3a/G3b populated won blocks), diff held low |
+| Sharechain IDENTIFIER (bucket-1, `--network-id`) | `d3a5c0920263617` (private; both pools peer as ONE sharechain) |
+| Sharechain PREFIX (bucket-1, `--prefix`) | `446173686721` (independent constant — no algebraic tie to IDENTIFIER) |
+| POOL O (oracle v16 p2pool-dash, ver=16) | p2p `7903`, stratum `7902` |
+| POOL V (v36 c2pool-dash) | p2p `8903`, stratum `8902`, web/stats `8350` |
+| Parent dashd | rpc `19998`, p2p `19999`, self-service creds (600, not on any card; VMID 200/201 via `ssh pve`) |
+| Staged-migration shape | `STAGES=7` miners staged ONE AT A TIME |
+| Run SHA (c2pool-dash) | `__________` |
+| Date / operator-acked | `__________` |
+
+## The 5 checks
+
+| # | Check | Property under test | Evidence | Verdict |
+|---|---|---|---|---|
+| G1/anchor | VERSION_GATE SSOT + weighted rule | The 16→36 boundary the ratchet keys off: `core::version_gate` `is_v36_active(36)=true` / `(16)=false`, `V36_ACTIVATION_VERSION=36`, plus the weighted accept/activate rule. **Rig-free, provable NOW on master.** | **PASS** `test_dash_conformance` — `DashConformanceVersionNeg.{SuccessorGuard60PercentWeightedKat, V36GateWeighted95PercentKat, GateUsesWeightNotPlainCount, SwitchClassifier5CaseKat}` + `DashConformanceVersionWiring.*` | ☑ PASS (no rig dependency) |
+| C1 | BASELINE COHABIT | v36 c2pool-dash peers the v16 p2pool-dash oracle on the private `IDENTIFIER` and **accepts** v16 shares (backward-compat in-window). No sharechain split. Work-weighted tally **readout mechanism** (`sampling_desired_version` / `shares_by_desired_version` on `/local_stats`) confirmed reachable. | substrate + readout reachable on provision / live-peer+v16-accept: `__________` | ☐ substrate reachable · live [GATED: rigs] |
+| C2 | VOTING MINT | In VOTING, c2pool-dash mints `base_version=16` (oracle-faithful) and advertises `desired_version=36` (the vote); **no premature v36-format mint**. **LOGIC sim-proven** by `DashConformanceVersionWiring` (`SameVersionAdmitted` / `StalePreV36ShareRejected`). | logic PASS (master) / LIVE mint: `__________` | ☑ logic PASS · live [GATED: rigs] |
+| C3 | STAGED ACCEPT GATE (#288-class) — **THE acceptance criterion** | Miners staged **ONE AT A TIME**; after each stage the work-weighted v36 tally (`sampling_desired_version`) must advance **MONOTONICALLY** (hard-fail on any regression at a stage boundary), and the 95%-**by-COUNT** activation must NOT flip `VOTING→ACTIVATED` until work ≥ **60%**. Mint **cannot outrun accept**. **Per-stage tally captured in the RESULT line.** **ORDERING LOGIC sim-proven** by `DashConformanceVersionNeg` (weighted 60% / weighted 95% / weight-not-count / 5-case switch). | logic PASS (master); asserts armed (monotonic + #288 ordering) / per-stage LIVE tally readout: `__________` | ☑ logic PASS · live [GATED: rigs] |
+| C4 | RATCHET + PERSIST | On 60%-by-work + 95% sustained for `2*CHAIN_LENGTH`: VOTING→ACTIVATED→CONFIRMED; v36-format mint begins; v16 oracle still accepts in-window; **CONFIRMED survives c2pool-dash restart**. Persisted-latch state machine = **Component A #466** (tap-bound); its **8/8 KAT** sim-proves the transitions + restart-survival off the master gate. | latch sim lands with #466 / LIVE: `__________` | latch sim ☐ (#466) · live [GATED: rigs] |
+| C5 | ALGO POSTURE | DASH is **single-algo by construction** — X11 is THE one validated/work-weighted algo; there is no multi-algo leg to gate (contrast DGB's scrypt-among-5; same posture as BTC's SHA-256d). Recorded explicitly — **not a skipped check**. | by construction (no other DASH PoW algo exists) | ☑ PASS (no rig dependency) |
+
+## DASH advantage over BTC #436 (why more rows are sim-green here)
+BTC had **no AutoRatchet ctest** — its C2/C3/C4 staged-gate logic could only be proven LIVE/rig-fed. DASH (like DGB #427) carries a real **weighted-gate KAT suite on master** (`test_dash_conformance` `VersionNeg.*` + `VersionWiring.*`), so the staged-gate **LOGIC** — weighted accept ≥60%, weighted v36 gate ≥95%, weight-not-count, the 5-case switch classifier, and the wired-path admit/reject — is **sim-proven rig-free NOW**. Only the **LIVE work-weighted tally** through staged X11 stratum miners needs the rig window. DASH also **has a real `--regtest` parent** (BTC had to fall back to an isolated testnet).
+
+## Rig dependency (why C1–C4 LIVE rows are GATED)
+C1/C2/C3/C4 **live** work-weighted evidence needs real **X11 hashrate** to move `sampling_desired_version` through staged stratum miners. The valid rig set is in the **LIVE LTC crossing-soak** (owner: ltc-doge-production-steward). Per the DGB #427 / BTC #436 precedent: **author first, then request the rig window — do NOT pull rigs off a live soak.** The harness arms the monotonic + #288-ordering asserts and confirms the readout mechanism now; the LIVE rows carry a verdict once a rig-fed run drives non-zero work weights.
+
+→ **Open to integrator:** request the X11 rig window to run C1–C4 **live**. No sim gap to close (unlike BTC): DASH's staged-gate logic is already sim-covered on master; C4's persisted-latch sim lands when **Component A #466** is tapped.

+# Greenlight gate G2 -- DASH RATCHET STAGED-MIGRATION test harness.
+#
+# Gate sequence (mirrors DGB #427 / BTC #436, per integrator 2026-06-24):
+# G1 (version_gate SSOT boundary KAT) -> G2 (this: ratchet staged-migration) ->
+# G3a/G3b (regtest block PRODUCTION, already PROVEN: populated won blocks
+# crossed + submitblock-accepted on regtest, c2pool-dash).
+#
+# WHAT G2 PROVES
+# --------------
+# DASH conforms to its OWN oracle frstrtr/p2pool-dash @9a0a609 (sharechain
+# share VERSION=16, NOT v35); c2pool-dash drives the 16 -> 36 ratchet while
+# staying backward-compatible with the v16 oracle during the migration window.
+# This is the DASH per-coin migration gate against its OWN oracle -- a SEPARATE
+# X11 sharechain, NOT the LTC v35 crossing (never wait on the LTC soak; DASH is
+# UNFENCED from it, operator 2026-06-17).
+#
+# The single axis under test is the work-weighted desired-version TALLY: miners
+# are staged onto the v36 vote ONE AT A TIME (not a flat flip), and the
+# work-weighted v36 tally (sampling_desired_version) must advance MONOTONICALLY
+# per stage, while the 95%-by-COUNT activation trigger stays GATED behind the
+# 60%-by-WORK accept (the #288-class rule) so mint cannot outrun accept.
+#
+# SSOT: core::version_gate (is_v36_active / V36_ACTIVATION_VERSION=36) governs
+# the share encoding / consensus revision. The DASH gate-logic the ratchet keys
+# off is already on master as dash::verify_version_transition + the weighted
+# accept/activate rule, exercised by test_dash_conformance
+# (DashConformanceVersionNeg.* + DashConformanceVersionWiring.*). The persisted
+# VOTING -> ACTIVATED -> CONFIRMED state-machine latch is Component A (#466,
+# tap-bound) -- its sim arrives when #466 lands; the gate it latches off is on
+# master NOW.
+#
+# DASH ADVANTAGE OVER BTC #436: BTC had NO AutoRatchet ctest, so its C2/C3/C4
+# staged-gate logic could only be proven LIVE/rig-fed. DASH (like DGB) carries
+# a real weighted-gate KAT suite on master, so the staged-gate LOGIC -- weighted
+# accept >=60%, weighted v36 gate >=95%, weight-not-count, the 5-case switch
+# classifier, and the wired-path admit/reject -- is SIM-PROVABLE RIG-FREE NOW.
+# Only the LIVE work-weighted tally readout through staged X11 stratum miners
+# needs the rig window.
+#
+# ISOLATED TESTBED (bucket-1 isolation primitive, operator 2026-06-17 3-bucket
+# rule): unlike BTC, DASH HAS a --regtest parent (dashd regtest, the same
+# substrate that produced the G3a/G3b populated won blocks). The private
+# sharechain is pinned by --network-id (IDENTIFIER) + --prefix (PREFIX). These
+# are the per-coin / per-instance isolation boundary -- KEPT, never
+# standardized -- so this testbed is namespaced away from public DASH and every
+# other coin. diff-1 share target on the private sharechain; regtest diff held
+# low. Self-service RPC creds (no secret on any coordination card; dashd lives
+# on VMID 200/201, reachable via `ssh pve` -> `qm guest exec`).
+#
+#   POOL O (oracle v16)  : frstrtr/p2pool-dash @9a0a609 (share VERSION=16),
+#                          mints share version=16 / desired=16, P2P 7903.
+#   POOL V (v36 c2pool)  : c2pool-dash, ratchet VOTING->ACTIVATED->CONFIRMED,
