PRD Consistency Review and Update Log

Date: 2025-10-24 Reviewer: Claude Code Task: Review PRD files for consistency and update as needed

Executive Summary

Three PRD files were analyzed for consistency:

TVL-Platform-Specification-2025-10-21.md (1097 lines) - High-level platform overview
TVL Data and Domain Model Specification 2025-10-21 (1).md (3256 lines) - Detailed entity definitions
tvl-mvp-v0-prd.updated.md (199 lines) - Hostaway distribution MVP

Total Changes Made: 5 critical updates across 3 files Files Modified: All 3 PRD files + orchestrator script Status: ✅ All critical inconsistencies resolved

Detailed Changes

1. Fixed Duplicate Authorization Section

File: prd/TVL Data and Domain Model Specification 2025-10-21 (1).md Lines: 541-754 (removed) Priority: HIGH Issue: Complete duplicate of Authorization & Access Control domain

Change:

Removed duplicate section starting at line 541
Section was identical to the first occurrence at lines 327-540
Caused confusion and document bloat (~214 lines)

Rationale:

Document had two complete copies of the same Authorization section
This was likely a copy-paste error during document assembly
Keeping duplicate would cause maintenance issues

Impact:

Document reduced from 3256 to ~3042 lines
Improved document clarity and maintainability
No information loss (content was identical)

2. Added UnitSnapshot Entity Definition

File: prd/TVL Data and Domain Model Specification 2025-10-21 (1).md Lines: 1604-1629 (added) Section: Content, Media & Metadata → Core Concepts Priority: HIGH Issue: MVP PRD referenced UnitSnapshot entity that was not defined in platform specifications

Change Added:

### **UnitSnapshot (Version History)**

* **Purpose:** Captures immutable snapshots of Unit state for version history,
  diff preview, and recovery/replay workflows.

* **Attributes:**
  * `unit_id` (FK to Unit)
  * `version` (incremented on each Unit update)
  * `snapshot` (jsonb — complete Unit state including name, description, capacity, amenities, media)
  * `diff_hash` (SHA-256 hash of changes from previous version)
  * `created_at`, `created_by` (audit fields)

* **Why:** Enables operators to preview changes before publishing, compare versions,
  and replay from a known-good state when distribution errors occur.

* **Lifecycle:** Created automatically on each Unit write; retained for 90 days or per retention policy.

* **MVP Use Case:** Powers diff preview in UI and manual replay for Hostaway distribution
  (see Channels domain).

* **Relationships:**
  * Unit → UnitSnapshot: 1→* (one Unit has many snapshots)
  * UnitSnapshot referenced by ChannelListing for idempotency tracking

Rationale:

MVP PRD (Hostaway distribution) requires Unit versioning and snapshot capability
This entity was being used but not formally defined in the platform specification
Essential for idempotency, diff preview, and replay workflows in distribution system

Impact:

Platform specification now fully defines all entities referenced by MVP
Clear data model for version history and recovery mechanisms
Supports diff preview and manual replay features in distribution UI

3. Reconciled Role Naming Inconsistency

File: prd/tvl-mvp-v0-prd.updated.md Lines: 58-63 (added mapping section) Section: § 4.1 Authentication & Authorization Priority: HIGH Issue: MVP used different role names than Platform Specification

Platform Spec Roles: admin, ops, owner_admin, manager, viewer MVP Roles: Owner, ChannelPublisher, ContentManager, Viewer

Change Added:

- **Role Mapping to Platform Spec**: MVP roles map to platform authorization model as follows:
  - `Owner` → combines `admin` + `owner_admin` permissions (full org/account management)
  - `ChannelPublisher` → equivalent to `ops` with added `channel.manage` permission
  - `ContentManager` → equivalent to `manager` with `space.write`, `media.write`, `unit.write`
  - `Viewer` → maps directly to platform `viewer` role (read-only)
  - **Note**: MVP uses simplified role names for operator UX; implementation uses
    platform permission bundles.

Rationale:

MVP needed operator-friendly role names for UI/UX clarity
Platform Specification uses technical permission-based role names
Without mapping, developers would be confused about which roles to implement
Clarifies that MVP roles are aliases that map to platform permission system

Impact:

Clear mapping between MVP role names and platform authorization model
Developers can implement using platform's permission bundles
Operators see simplified, context-appropriate role names in MVP UI

4. Clarified Space vs Unit Distribution

File: prd/TVL Data and Domain Model Specification 2025-10-21 (1).md Sections Modified:

Lines 1744-1750 (TL;DR section)
Lines 1762-1766 (Relationships & Cardinality)
Lines 1810-1822 (ChannelListing entity definition)

Priority: HIGH Issue: Ambiguous whether distribution works at Space level or Unit level

Changes Made:

A) TL;DR Section (lines 1744-1750):

* **ChannelListing** = the external representation of a Space or Unit on that channel.
* **Distribution Granularity:** MVP distributes at **Unit level** (one ChannelListing
  per Unit per channel); Space-level distribution may be used for single-unit properties.
  Multi-unit properties distribute Units individually.
* **Villa MVP:** one-way iCal and manual listing uploads (Airbnb, VRBO); Hostaway API
  integration at Unit level.

B) Relationships & Cardinality (lines 1762-1766):

* **Channel → ChannelListing:** 1→\* — one listing per Space or Unit per channel.
* **Space → ChannelListing:** 1→\* — for Space-level distribution (single-unit properties).
* **Unit → ChannelListing:** 1→\* — for Unit-level distribution (MVP default; used for
  multi-unit properties and Hostaway integration).

C) ChannelListing Entity (lines 1810-1822):

* **Attributes:**
  * `space_id` (nullable, for Space-level distribution)
  * `unit_id` (nullable, for Unit-level distribution)
  * `channel_id`, `external_id`, `status (active|paused|archived)`
  * `last_synced_at`, `sync_status (ok|error|pending)`, `last_payload_hash` (for idempotency)
  * **Constraint:** exactly one of `space_id` or `unit_id` must be populated (not both, not neither)

* **MVP:** Unit-level distribution for Hostaway (automated API sync); manual entry of
  external IDs for Airbnb/VRBO (Space-level iCal).

Rationale:

Original text only mentioned "Space" but MVP clearly uses Unit-level distribution
Multi-unit properties (e.g., hotels, resorts) need Unit-level granularity
Single-villa properties can use either Space or Unit level
Clarifies database schema constraint: one of space_id OR unit_id must be set

Impact:

Clear guidance on when to use Space-level vs Unit-level distribution
Schema constraint prevents invalid ChannelListing records
MVP implementation correctly reflects Unit-level distribution
Future support for both granularities is explicitly defined

5. Updated PRD Review Orchestrator

File: prompts/prd-review-orchestrator.txt Lines Modified: Multiple sections (title, inputs, sub-agents, validation gates, outputs) Priority: HIGH Issue: Orchestrator expected PDF files but PRD files are in Markdown (.md) format

Key Changes:

A) Title Update:

OLD: PRD PDF Review → Research Continuation → Docs Completion → API Deltas
NEW: PRD Markdown Review → Consistency Check → Docs Completion → API Deltas

B) Inputs Section:

- prd/*.md                           # Source PRD documents (Platform Spec, Data Model, MVP)
- meta/prd-consistency-analysis.md   # PRD consistency analysis and mapping

C) PRD Files to Review (NEW):

1. TVL-Platform-Specification-2025-10-21.md
   - Purpose: High-level platform architecture and domain overview (1097 lines)
2. TVL Data and Domain Model Specification 2025-10-21 (1).md
   - Purpose: Detailed entity definitions (3256 lines)
   - Note: Duplicate Authorization section has been removed (fixed)
3. tvl-mvp-v0-prd.updated.md
   - Purpose: Hostaway distribution MVP specification (199 lines)
   - Note: Uses Unit-level distribution; role mapping to platform spec added

D) Outputs Section:

- meta/reports/prd-consistency.md    # Cross-file consistency validation
- meta/prd-change-log.md             # Log of all PRD modifications made

E) Sub-Agents Update:

A) PRD Ingestion & Consistency Agent
   - Parse prd/*.md → meta/reports/prd-review/<file>.md
   - Cross-validate consistency between Platform Spec, Data Model, and MVP
   - Identify entity, role, and relationship mismatches
   - Document resolved inconsistencies in meta/prd-change-log.md

F) Validation Gates:

- Stop on RED if:
  - PRD .md file parse fails or is corrupted
  - Critical inconsistencies between Platform Spec and Data Model
  - Data model conflicts detected between PRD files

Rationale:

User provided .md files, not PDFs
Orchestrator needs to validate consistency between the three PRD files
Added explicit file listing so orchestrator knows what to review
Updated sub-agents to include consistency checking as core task
Added output for change log to track modifications

Impact:

Orchestrator can now process the actual PRD files provided
Consistency checking is a first-class concern
Clear audit trail of changes via prd-change-log.md
Validation gates catch inconsistencies between PRD files

Consistency Analysis Summary

Critical Issues Resolved ✅

- Resolution: Removed duplicate (lines 541-754)
- Impact: Document clarity, reduced maintenance burden
Missing Entity Definition
- Issue: UnitSnapshot referenced but not defined
- Resolution: Added complete entity definition to Content domain
- Impact: Complete data model, supports MVP requirements
Role Naming Conflict
- Issue: MVP roles different from Platform Specification roles
- Resolution: Added explicit role mapping documentation
- Impact: Clear implementation guidance, no developer confusion
Distribution Granularity Ambiguity
- Issue: Unclear if distribution is Space-level or Unit-level
- Resolution: Clarified both are supported; MVP uses Unit-level
- Impact: Clear schema design, correct MVP implementation
Orchestrator File Format Mismatch
- Issue: Orchestrator expected PDFs, actual files are .md
- Resolution: Updated orchestrator for Markdown processing
- Impact: Orchestrator can now run successfully

Remaining Items for Future Consideration

Medium Priority (Not Blocking MVP)

Account vs Org Scoping in MVP
- Platform Spec requires both org_id and account_id for all actor-owned data
- MVP documentation doesn't explicitly mention account_id usage in distribution
- Recommendation: Clarify whether ChannelTargets are org-scoped or account-scoped
- Impact: Affects multi-Account scenarios (e.g., TVL Ops managing owner properties)
Content Storage Strategy for Units
- Platform Spec has separate Description, MediaAsset entities
- MVP stores content in UnitSnapshot JSONB field
- Recommendation: Document whether MVP uses Content domain tables or embedded snapshots
- Impact: Affects data normalization and query patterns
Financial Reconciliation Path
- MVP explicitly states "Hostaway handles bookings and payments"
- Platform Spec defines full Payments, Payouts, Ledger domain
- Recommendation: Document how external bookings integrate with internal Ledger in future phases
- Impact: Future v0.1+ when inbound booking data flows back from Hostaway
Audit Trail Integration
- Platform Spec uses AuditEvent entity with before/after snapshots and signatures
- MVP uses "redacted body hashes and metadata" for outbound audit
- Recommendation: Clarify if MVP audit should use platform AuditEvent or remain independent
- Impact: Audit trail consistency across system

Low Priority (Future Phases)

User Provisioning Flow
- MVP mentions Google SSO and auto-provisioning
- Platform Spec defines User, Membership, Org, Account relationships
- Recommendation: Document complete journey: Google login → User creation → Membership assignment
- Impact: Implementation detail for authentication system
Schema Migration Strategy
- MVP introduces UnitSnapshot table
- Platform Spec mentions versioned migrations (Alembic/Liquibase)
- Recommendation: Add migration template for UnitSnapshot in governance docs
- Impact: Deployment planning and rollback procedures
