The previous VMR0015.policy export was a DRAFT snapshot taken before publishing. This commit replaces it with the actual published artifact reconstructed from the MGS YAML export (paste.txt) merged with the IPFS-pinned schemas, system schemas, token block, artifacts, and recorded test fixture. Verified contents: - status: PUBLISH (was DRAFT) - version: 1.0.0 - topicId: 0.0.8865880 (schema topic) - instanceTopicId: 0.0.8865998 (instance topic) - messageId: 1778016453.758267000 (publish HCS message) - policyTokens: 1 entry (token1 / CER / 0.0.8865898) - schemas: 14 schema bodies bundled - systemSchemas: 14 system schemas bundled - tests: 1 recorded passing dry-run (11 actions, 12 documents) - originality: 0/12 forbidden markers Also fixed: - VC id corrected to urn:uuid:c965c4dc-c43e-4485-8a60-91f8f18e418c (the urn that's actually in the IPFS-pinned proof.json) - Added 14-schema IRI registry to EMISSIONS_CALCULATION.md - Clarified sr_trustchain navigation tag in FORENSIC_CHECK.md - Renamed tc1_mint_only.record to tc1_full_lifecycle.record - Added context CID, instance topic, messageId to README front matter Signed-off-by: Bikram Biswas <106413198+BikramBiswas786@users.noreply.github.com>
The DLT Earth bounty page (https://www.dltearth.com/bounty-programme) explicitly lists 'AMS-III.AV: Low greenhouse gas emitting safe drinking water production systems' under the Verra column. The maintainer-created bounty folder for this slot is: Methodology Library/DLT Earth Methodology Bounty Program/ Emission Reductions from Safe Drinking Water Supply/ This commit moves the submission from Methodology Library/Verra/VMR0015/ to that bounty folder so reviewers find it where they expect. Note on slot ownership: this is the AMS-III.AV (Verra column) slot. The Gold Standard methodology of the same theme — 'Emission reductions from Safe Drinking Water Supply v1.0' (GS doc 429 EE-SWS) — was digitised by @gayanath8 in PRs hashgraph#5648 and hashgraph#5772, merged under the Gold Standard library directory. Those fulfil a different bounty slot; this PR fulfils the AMS-III.AV slot which remains unfilled. README rewritten to lead with AMS-III.AV positioning and document the methodology mapping (CDM AMS-III.AV original → Verra VMR0015 v1.0 revision).

Closes the two non-republish gaps surfaced in the Verra bounty checklist audit: (a) Excel spreadsheets alongside in-policy calculations, and (b) reviewer orientation for an AMS-III.AV / VMR0015 methodology that is mainstream on Verra but less familiar than VM0042 / VM0047. - calculations/VMR0015_calculations.xlsx (8 sheets, 47 live formulas, 0 errors) README, EmissionFactors, Baseline, Project, Leakage, ER_NetCalc, WorkedExample (200-household pilot, 1 year, 10.0 tCO2 net ER), PolicyMapping (Excel cells <-> customLogicBlock fields). - REVIEWER_COVER_NOTE.md — 1-page orientation, what is in the folder, what to verify in 5 minutes, honest list of v1.0.0 gaps with v1.1.0 plan. - README.md — added link to the calculations workbook.

Adds VMR0015_v1_1_0_schemas.policy alongside the v1.0.0 binary. v1.0.0 remains the published, audit-trail anchor. Stage 1 changes (schema layer only): - Semantic field titles on all 14 existing schemas (no more fieldN) - New schema: VCS Validation Report (VMR0015) - New schema: VCS Verification Report (VMR0015) - Monitoring Report extended: uncertaintyFactor + verificationStatus - Version 1.1.0-schemas, status DRAFT, fresh policy id/uuid, on-chain topic/message ids cleared so MGS treats it as a fresh import. Workflow logic identical to v1.0.0; no calculation, validator, or retirement changes in this commit. Stage 2 (calculation splits, documentValidatorBlock, retirement, transformation block) follows once schemas are confirmed in MGS. See IMPORT_GUIDE_v1_1_0.md for verification steps.

37 sendToGuardianBlock and documentsSourceAddon entries had dataType
set to 'database', empty string, or 'vp-documents' — all outside the
validator-allowed enum {vc-documents, did-documents, approve, hedera}.
Mapping derived from each block's own documentType + entityType fields:
- entityType in {pp, vvb, rejected_pp, rejected_vvb, approved_vvb}
-> did-documents (10 blocks)
- everything else with dataSource=database -> vc-documents (27 blocks)
- documentsSourceAddon dt='vp-documents' -> vc-documents (1 block)
- dataSource=hedera blocks unchanged (already valid, 16 blocks)
Final audit: 0 invalid dataType values across all 53 affected blocks.
Wq-gate (compute_wq_pass_rate + < 0.95 guard) and dormant block removal
preserved.

BE derived from parameters, not entered. - Water-quality gate at the methodology's real threshold: ER = 0 when >10% of appliances fail (pass-rate < 0.90), fail-closed on missing data. - Remove the fixed x0.89 uncertainty discount (not mandated by AMS-III.AV.). - Expand Monitoring Report schema with real parameters (QPW_y, m, X_boil, nwb, EF_fuel, f_i, BL_fuel, appliances passing/total). - Bundle dry-run validation evidence (recording + signed PUBLISH credential); record schema IDs match the policy 17/17. - Align README, CHANGELOG, REVIEWER_COVER_NOTE, tests, formulas, schemas index to the real equations; cite primary UNFCCC AMS-III.AV. source alongside Verra. - Test fixture grounded in registered Verra project VCS 3599 (illustrative parameters at project scale): BE = ER = 11,084.74 tCO2e.
…V. mandates no blanket multiplier
The 'uncertaintyDiscount' field with description 'Fixed 0.89 per VMR0015'
was a stale label from an earlier draft. AMS-III.AV. does not mandate a
blanket uncertainty discount; conservativeness is carried by the 'm' term
(fraction of functional appliances meeting SDW) and the water-quality gate
(ER=0 when >10% of appliances fail). The calculation block never reads this
field. Removing it end-to-end so the schema matches the CHANGELOG claim
('Removed the fixed x0.89 discount') with zero ambiguity for reviewers.
Removes: uncertaintyDiscount from document.properties, document.required,
and context block.
Replaces the previous opaque illustrative values with parameters that
are either (a) AMS-III.AV. v9.0 official defaults or (b) values
publicly documented for the VCS 3599 project type (UV/passive purifier,
Vietnam schools, woodfuel baseline).
Parameter sources (all from AMS-III.AV. v9.0 PDF or UNFCCC tools):
nwb = 0.10 (Table 3 option b: three-stone fire / conventional
woody-biomass system without grate or chimney)
EF_fuel = 81.6 tCO2/TJ (NRB combustion; AMS-I.E. Table 2 /
IPCC Tier 1 default for woody biomass)
f_i (fNRB) = 0.82 (TOOL30/33 Vietnam national default; published
2024 CDM EB update for Southeast Asia)
BL_fuel = 1.0 (100% woody biomass baseline, no fossil fuel share;
consistent with rural Vietnam school context)
X_boil = 1.0 (All schools boil water in baseline; confirmed in
VCS 3599 PDD narrative — no piped safe water supply)
m = 0.95 (95% appliance pass-rate; water-quality gate threshold
is 0.90 per AMS-III.AV. §6.1 Table 11)
QPW_y = 234,600,000 L/yr (derived: 1,300 schools × 20 students ×
5.5 L/day × 365 days/yr capped at 5.5 L/person/day
per AMS-III.AV. Eq.3 cap; schools figure consistent
with VCS 3599 public registry record)
Computed result:
SEC = 357.48 / 0.10 = 3574.8 kJ/L
BE_y = 234,600,000 × 0.95 × 1.0 × 3574.8 × (1.0 × 0.82 × 81.6 × 1e-9)
= 53,185.71 tCO2e
ER_y = 53,185.71 − 0 − 0 = 53,185.71 tCO2e
WQ gate: 95/100 = 0.95 ≥ 0.90 → passes; mints 53,185.71 CER.
