Work definition Stable undertaking identity and its physical context.
Identity and scope
Preserve the work identifier across revised scope, completion and later defects. Classification and supersession are explicit local decisions.

What it is Filled
A persistent work entity for construction, alteration, repair or demolition of built assets, carrying scope, site references, responsibilities, plans, observations and outcome evidence. All structures and functions below are proposed local research design informed by cited sources, not prescribed universal schemas or operational engineering instructions.
In scope
- Work identity, classification and scope revisions
- Sites, affected assets and external project or task references
- Profile-specific authority, role and permit assertions
- Baselines, sequencing, progress, suspension and change evidence
- Material traceability, environmental disposition and safety governance references
- Inspection, nonconformity, partial acceptance and handover records
Out of scope
- Portfolio and contract accounting, wages, invoices and ownership transfer
- Asset geometry masters, structural calculations, design approval or autonomous site control
- Issuing permits, certifying occupancy, accepting works or ordering suspension through model functions
- Detailed hazardous-material, demolition or emergency-response procedures
Why it exists Filled
Describe and review one bounded construction undertaking from definition through execution, partial outcomes and retained completion history.
Distinguishing features Derived, awaiting review
- Unlike WM-ACT-005 Project: Project governance, finance and portfolio identity remain external. This root is a persistent construction undertaking with its own execution scope; a small undertaking need not have a separately instantiated project record.
- Unlike WM-ACT-006 Task / Work Item: Tasks are execution units referenced by the work breakdown. A task completion event does not close the undertaking or certify its product.
- Unlike WM-BLT-001 Building / Structure and WM-BLT-003 Infrastructure Network: Produced, altered or removed assets retain separate identities before and after acceptance. A demolition undertaking may produce no new asset. Work history does not change class into the product.
- Unlike WM-PLC-002 Land Parcel: Site and affected parcel references locate work; they do not establish title, access rights or property boundaries.
- Unlike WM-POL-004 Permit / Authorization: Permit decisions and their authoritative terms are referenced. An undertaking can lack a permit because none is required, an application is pending, or unauthorized work occurred; these states must remain distinguishable.
- Unlike WM-ACT-013 Maintenance: Maintenance management can commission a bounded construction undertaking. Permit presence alone does not distinguish maintenance from construction; record the adopted classification and link both masters without duplicating work.
- Unlike WM-ACT-019 Incident / Emergency: Incident reports and emergency response remain externally mastered; this record carries restricted references and effects on work status.
- Unlike Contract, design and inspection masters: Contracts, approved designs, formal tests and legal decisions are referenced with revisions and issuer scope. This model stores work-specific assertions and trace links, not replacement legal or engineering masters.
Note: Derived from boundary notes against neighbouring models.
What robots and AI may and may not do Derived, awaiting review
Must not
- Record unauthorized, unsafe or disputed observations honestly while flagging the exception; never suppress facts to satisfy a readiness rule.
- Deny by default; grant purpose-limited role access to the minimum work scope, fields and artifact revisions.
May
- Register work identity: Proposed, unimplemented local operation. Create a proposed local undertaking record with scope and separately mastered context.
- Record baseline revision: Proposed, unimplemented local operation. Preserve a previous baseline and record a new decision-backed revision.
- Record progress evidence: Proposed, unimplemented local operation. Capture an observation and assess its measurement basis without certifying completion.
- Link inspection or correction review: Proposed, unimplemented local operation. Attach scoped evidence and record a qualified review state.
- Record an external outcome: Proposed, unimplemented local operation. Record a partial acceptance, suspension or other externally issued decision as evidence.

Note: Derived from functions, policies, CRUD and access rules; prohibitions were not authored for agents as such.
Moral aspects Derived, awaiting review
- Delete eligible payloads only under authorized retention and privacy policy, retaining only lawful minimal tombstones and non-sensitive referential metadata; history does not justify indefinite personal-data storage.
Note: Sentences mentioning harm, privacy, consent or similar, collected from the specification.

Open questions

- Independent external review is absent; Claude and Grok skipped under the owner waiver.
- Direct HTTP checks unattempted under the owner-reported sandbox restriction; browser readings are not measured HTTP status or independent verification.
- Current applicable law, contract deviations, permit and occupancy regimes, translations and licensing require qualified adopter review.
