Data Model: Verification Checklist Framework V1.5 (075)

Date: 2026-02-05
Phase: Phase 1 (Design)
Status: Draft (design-complete for implementation planning)

Existing Entity (reference)

OperationRun (existing)

Purpose: Canonical operational record. Verification reports are stored in operation_runs.context.verification_report (JSONB).

Key fields (relevant):

id
tenant_id
workspace_id
type (verification flow identifier)
run_identity_hash (identity hash used for active dedupe + identity matching)
status
context (JSONB)

Verification report storage:

context.verification_report (JSON object)

New Persistent Entity

VerificationCheckAcknowledgement (new table)

Table name: verification_check_acknowledgements

Purpose: First-class governance record that a failing/warning check is acknowledged for a specific report (report == operation run).

Fields:

id (primary key)
tenant_id (FK or scalar; used for tenant-scoped filtering and isolation checks)
workspace_id (FK or scalar)
operation_run_id (FK to operation_runs.id) — the “report”
check_key (string)
ack_reason (string, max 160)
expires_at (timestamp, nullable) — informational only in v1.5
acknowledged_at (timestamp)
acknowledged_by_user_id (FK to users.id)
created_at, updated_at

Uniqueness constraint (required):

unique (operation_run_id, check_key)

Indexes (recommended):

(tenant_id, workspace_id, operation_run_id)
(operation_run_id)

Validation rules:

ack_reason: required, string, length ≤ 160
expires_at: optional, must be a valid timestamp, should be >= acknowledged_at (implementation may enforce)

State transitions:

Immutable per report/check in v1.5: create once; no update/delete/unack flows.

Contracted Document (stored in JSON)

VerificationReport (JSON in `OperationRun.context.verification_report`)

Purpose: Structured, versioned report of verification results used by the DB-only viewer.

Identity:

report_id: operation_runs.id
previous_report_id: previous run id for same identity (nullable)

New v1.5 fields:

fingerprint (string; lowercase hex; SHA-256)
previous_report_id (nullable integer/uuid depending on OperationRun PK type)

Existing core fields (from 074, reference):

schema_version (SemVer string; major 1)
flow (verification flow identifier; aligns with OperationRun.type)
generated_at (timestamp)
summary (counts + overall outcome)
checks[] (flat array) including:
- key
- title
- status (pass|fail|warn|skip|running)
- severity (info|low|medium|high|critical or empty string)
- blocking (boolean)
- reason_code (string)
- safe evidence pointers
- next_steps[] (navigation-only links)

Fingerprint normalization input (strict):

Flatten all checks across checks[].
Sort by check.key.
Contribute the stable tuple string:
- key|status|blocking|reason_code|severity
- severity must always be present (missing normalized to empty string).

Derived/Computed View Data (not persisted)

Change indicator

Computed in the viewer by comparing:

current verification_report.fingerprint
previous verification_report.fingerprint

States:

no previous report → no indicator
fingerprints match → “No changes since previous verification”
fingerprints differ → “Changed since previous verification”
