--- phase: 13-data-flow-architecture-document verified: 2026-03-22T10:15:00Z status: passed score: 7/7 must-haves verified re_verification: false gaps: [] human_verification: [] --- # Phase 13: Data Flow Architecture Document — Verification Report **Phase Goal:** Create DATA-FLOW.md authoritative data flow reference document with agent rules, four data layers, sync pipeline, storage architecture, and CLAUDE.md enforcement. **Verified:** 2026-03-22T10:15:00Z **Status:** PASSED **Re-verification:** No — initial verification --- ## Goal Achievement ### Observable Truths | # | Truth | Status | Evidence | | --- | ----------------------------------------------------------------------------------------- | ---------- | ---------------------------------------------------------------------------------------------- | | 1 | DATA-FLOW.md exists as a layered reference with field tables and ASCII flow diagrams | VERIFIED | `.planning/DATA-FLOW.md` exists, 811 lines, Unicode box-drawing diagrams in Overview, Sync Pipeline, Transformation Pipeline sections | | 2 | Document covers all four data layers: Recipients, Cards, Products, Serial Instances | VERIFIED | Sections confirmed at lines 179, 243, 295, 351 | | 3 | Document includes prescriptive AGENT RULES section at the top | VERIFIED | `## AGENT RULES` at line 13 with RULE-01 through RULE-08, each with Status/Background/Action | | 4 | Document defines SQLite full-mirror cache architecture | VERIFIED | `## Storage Architecture` at line 594; nine normalized tables, schema philosophy, offline mode, conflict resolution documented | | 5 | Document defines GH Issues storage model (ww-card, ww-product) | VERIFIED | `ww-card` and `ww-product` storage in `BigscreenVR/beyond-outgoing` documented in Layer 2 (line 246), Layer 3 (line 297), and Storage Architecture sections | | 6 | Document corrects github_profile_url assumption prominently | VERIFIED | RULE-01 (line 19) is PROHIBITED status; `github_profile_url` appears 7 times across the document with REMOVE/PROHIBITED designations in field tables | | 7 | CLAUDE.md contains mandatory read + update obligation for DATA-FLOW.md | VERIFIED | CLAUDE.md lines 3-13: `## Data Architecture` section with mandatory read obligation, four enforced rules referencing DATA-FLOW.md, and explicit update obligation | **Score:** 7/7 truths verified --- ### Required Artifacts | Artifact | Expected | Status | Details | | ------------------------- | ------------------------------------------------ | ---------- | ----------------------------------------------------------------------------------------- | | `.planning/DATA-FLOW.md` | Authoritative data flow reference, min 300 lines, contains "github_profile_url" | VERIFIED | Exists, 811 lines (>300), contains "github_profile_url" 7 times, all 4 data layers, AGENT RULES, ASCII diagrams, SQLite schema | | `CLAUDE.md` | Agent enforcement blurb pointing to DATA-FLOW.md | VERIFIED | Contains `## Data Architecture` section with 4 enforcement rules, mandatory read/update obligation, pointer to DATA-FLOW.md | --- ### Key Link Verification | From | To | Via | Status | Details | | --------- | --------------------- | --------------------------------- | -------- | ---------------------------------------------------------------------------------------------- | | `CLAUDE.md` | `.planning/DATA-FLOW.md` | pointer and obligation text | VERIFIED | CLAUDE.md line 5 and 8 and 11 and 13 all reference `DATA-FLOW.md` directly; mandatory read obligation and update obligation both present | --- ### Requirements Coverage No formal requirement IDs were assigned to this documentation phase (`requirements: []` in PLAN frontmatter). No REQUIREMENTS.md cross-reference needed. No orphaned requirements found for Phase 13 in `.planning/REQUIREMENTS.md`. --- ### Anti-Patterns Found | File | Line | Pattern | Severity | Impact | | ------------------------- | ---- | -------------- | -------- | ------------------------------------------- | | `.planning/DATA-FLOW.md` | 756 | "Transitional placeholder" in deprecated-fields table | Info | Documents an existing placeholder field (`package_id`/`active_item_id`) as migration debt — this is intentional documentation of technical debt, not an anti-pattern in the document itself | No TODOs, FIXMEs, or stub-style content found. The single "placeholder" occurrence is describing a deprecated Rust field, not a documentation gap. --- ### Human Verification Required None. This is a documentation-only phase. All observable truths are verifiable against file content. --- ### Commit Verification Both documented commits exist in repository history: - `5df751a` — `feat(13-01): create DATA-FLOW.md authoritative data architecture reference` - `11aeab1` — `feat(13-01): add DATA-FLOW.md enforcement blurb to CLAUDE.md` --- ### Document Quality Notes The DATA-FLOW.md contains: - RULE-01 through RULE-08 with Status/Background/Action format at document top (lines 13-131) - Unicode box-drawing diagrams in Overview (line 138), Sync Pipeline (line 421), and Transformation Pipeline sections - Field tables with Field | Type | Source | Status | Notes columns for all four layers - Nine-table SQLite schema with column definitions and FK constraints - Shipment status mapping table, customer_id extraction rules, and write-back path documentation - Slint CardData field mapping table (14 fields) within Transformation Pipeline section - Deprecated fields consolidated table (7 deprecated fields with replacement guidance) - Open questions documented as OQ-01/OQ-02/OQ-03 The CLAUDE.md enforcement blurb contains "you and your subagents MUST read" (slightly expanded from the plan's "you MUST read") — this is strictly stronger enforcement and not a deviation. --- ### Gaps Summary No gaps. All 7 must-haves are fully verified. The document is substantive (811 lines against a 300-line minimum), all required sections are present and non-stub, and the key link from CLAUDE.md to DATA-FLOW.md is wired with mandatory language. The phase goal is achieved. --- _Verified: 2026-03-22T10:15:00Z_ _Verifier: Claude (gsd-verifier)_
