Supply identity and responsibility Define the system, use profile and accountable interfaces.
System identity and service boundary
Proposed aggregate boundary ties a service area and intended use to time-qualified member references; membership does not transfer asset ownership.
System identity and service boundary
Proposed aggregate boundary ties a service area and intended use to time-qualified member references; membership does not transfer asset ownership.
- Which master identifier and aliases identify this supply system across renaming or operator change? identity
- Which intended uses and delivery modes define the service profile and its exclusions? classification
- What service-area geometry and effective dates determine the included zones and delivery points? spatial
Responsibility and applicable profile
Responsibility, regulatory applicability and data stewardship are distinct assertions. A supplier handoff need not coincide with a legal compliance location.

Sources and resource availability Connect source context to recorded abstractions and supply availability.
Source context and protection
Source context references catchment and raw-water risk evidence. This model does not calculate hydrology or grant abstraction rights.

- Which hazard categories and hazardous events are covered by the current supply risk assessment? quality
- Who accepted the residual-risk assessment and prioritized improvements using which method? decision

- Which operational deviations were observed and which authorized corrective-action records address them? event
Observations and quality interpretation Preserve sampling provenance and constrain what a quality assessment can establish.
Sampling and observation context
Observation identity and target must survive correction. A sample applies to its declared location, time and method, not automatically the entire supply.

- How do collection time, phenomenon interval, result time and ingestion time differ? temporal
- Which property, location, value, unit, detection qualifier and uncertainty describe the result? measurement
Quality assessment and limits
An authored assessment links observations to the applicable versioned rule and comparison method. Unknown, pending and invalid inputs cannot silently become passing results.

- What assessment status and competent review evidence distinguish an exceedance flag from a safety determination? state
Distribution and storage Time-qualified network and storage assertions describe delivery without inventing complete physical traceability.
Network connectivity and delivery context
Topology, pressure and delivery evidence have separate time and confidence. Continuous-flow mixing makes exact lot-to-tap attribution an unsupported default.

What it is Filled
One declared supply-system aggregate links independently mastered sources, facilities, zones and delivery points across an effective period. Drinking-water service is the core profile; nonpotable use must carry an explicit separate profile. The aggregate owns supply-specific assertions and evidence references, not the assets, water bodies, regulator, laboratory or physical controls.
In scope
- System identity, service area, intended use, accountable roles and responsibility interfaces
- Source and abstraction evidence, treatment assurance, monitoring and quality assessment references
- Time-qualified distribution, storage, supply quantity, continuity and authorized communication records
Out of scope
- Food production, agricultural lots, food processing, cold chains and food recalls belong to WM-FLW-003
- Water body hydrology, land and asset master lifecycles, energy dispatch, generic consignment custody, wastewater and residuals processing
- Engineering design, treatment dosing, network actuation, emergency command, public notice issuance, billing and legal compliance certification
Why it exists Filled
Describe a governed water supply system and its evidence of source, treatment, delivery, quality and continuity.
Distinguishing features Derived, awaiting review
- Unlike Legacy F4 and WM-FLW-003 Food Supply Chain: F4 mixed water and food. Retain only water supply concerns. Do not require a batch for continuous flow or retain agriculture and cold-chain layers. The unreviewed supplement repeats this scope leakage and is not evidence.
- Unlike WM-PLC-003 Water Body and WM-PLC-002 Land Parcel: Reference catchments, water bodies and locations; keep hydrologic behavior, rights registers and parcel identity externally mastered.
- Unlike WM-FLW-004 Goods Movement / Logistics and WM-FLW-001 Energy: Optional delivery and energy dependency references do not imply generic logistics inheritance for a continuous pipe network.
- Unlike Premise plumbing, wastewater and treatment assets: Record the point of supply separately from the compliance point and consumer tap. Link premise responsibilities and residual handoffs without taking ownership of those systems.
Note: Derived from boundary notes against neighbouring models.
What robots and AI may and may not do Derived, awaiting review
Must not
- Treat public health restrictions and control changes as externally authorized decisions; local functions cannot issue notices or actuate systems.
- Deny detailed infrastructure and personal-data access unless authorized by purpose and role; release only approved public views.
May
- Register supply boundary: Proposed local operation records a versioned system boundary and external master references.
- Link qualified observation: Proposed local operation attaches evidence without changing a laboratory or sensor master record.
- Record scoped assessment: Proposed local operation records a reviewed comparison and flags unknown inputs; it does not determine potability.
- Record delivery scenario: Proposed local operation links a supplied simulation result; it does not run hydraulic calculations or operate equipment.
- Record continuity event: Proposed local operation links interruption and recovery evidence without executing response actions.
- Prepare authorized evidence view: Proposed local operation prepares a locally reviewable summary with approved notice links; it does not send or publish a notice.
Note: Derived from functions, policies, CRUD and access rules; prohibitions were not authored for agents as such.
Moral aspects Derived, awaiting review
- Use minimum necessary personal data, scoped infrastructure access and approved public views.
Note: Sentences mentioning harm, privacy, consent or similar, collected from the specification.
