Draft consultation shape

TLA-EVID — Landscape evidence / audit pack

Draft orbit: open evidence and audit pack shape for sustainability, climate, and botanical claims.

Schema id: la.archive.audit-pack.v1 · Spine: TLA-185

Purpose

Define a portable audit / evidence pack so a project handover can answer which sustainability, climate, or botanical claims were made; which TLA-185 fields those claims sit on; what evidence URIs or method notes support them; and what remains professional judgement versus documented evidence.

This orbit packages how claims point at evidence. It does not replace Archive Seal, Foundation Approved criteria (when published), or a second field dictionary.

Out of scope

Not this orbit	Where it lives
GHG inventory methodology	Specialist carbon protocols
Legal / statutory filings	Jurisdiction-specific compliance
Archive Seal issue or crypto manifests	Commercial Archive attestation
World flora dump	Forbidden expansion path

Enumerations (draft — freeze later)

Field	Allowed values (draft)
`claims[].topic`	`botanical \| climate \| sustainability \| risk \| cultural \| synthetic \| other`
`claims[].evidence[].kind`	`method_note \| dataset \| report \| photo \| survey \| standard_ref \| other`
`claims[].confidence`	`documented \| partial \| asserted_without_uri \| unknown`

Normative intent (when elevated from Draft)

When elevated from draft: claims that appear in TLA-185 sustainability / climate fields should be linkable from an audit pack via tla185.field_id or json_path.
Missing evidence is expressible (confidence, residual_judgement) — silence is worse than “asserted without URI”.
Cultural restricted material may be flagged and excluded from the open pack; do not dump sensitive content into a public evidence URI list.

Foundation vs Archive

Foundation	Archive
Publishes the open evidence structure — free to cite when elevated.	May implement richer audit tooling and paid attestation products.
Foundation Approved (when criteria published) is open-spec conformance assessment.	Archive Seal is commercial period-bound attestation.
