# Phase 20.5: Modal State Architectural Audit — Verification Report

**Phase Goal:** Inventory every modal in the app, document every callback in/out, identify every place modal state is read or mutated, and produce a canonical state diagram in `.planning/MODAL-STATE.md`. Subsequent modal changes must update this doc.
**Verified:** 2026-04-16
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | MODAL-STATE.md contains a section for every overlay component in the app (9 total) | VERIFIED | Inventory table has 9 rows (`grep "^| [0-9]"` = 9); 9 modal sections (`grep "^## [0-9]"` = 9) |
| 2 | Each modal section has a Mermaid stateDiagram-v2 block | VERIFIED | `grep -c "stateDiagram-v2"` = 9; one per modal section confirmed in file |
| 3 | Each modal section has a callback table with columns: Callback Name, Direction, Source, Handler, Side Effects | VERIFIED | `grep "Callback Chains"` = 9 matches; all 9 sections contain the table with correct column headers |
| 4 | Full callback chains are documented end-to-end (Slint -> dashboard -> main.rs -> side effects) | VERIFIED | All callback tables include Source (slint file), Handler (dashboard.slint routing + main.rs line numbers), and Side Effects columns with real data. E.g., LookupModal `close-requested()` traces to main.rs:4671 |
| 5 | Known fragile patterns are documented inline with RETRO cross-references | VERIFIED | 11 occurrences of C-3/D-4/F1/bac9584 in FRAGILE blockquotes across modal sections. RETRO IDs reference real entries in RETRO-AGENT-FAILURE-PATTERNS.md |
| 6 | Agent Rules section with RULE-M-01 through RULE-M-04 | VERIFIED | `grep "RULE-M-0[1-4]"` = 14 hits; all 4 rules present in `## Agent Rules` section |
| 7 | Esc Priority Chain section documents all 5 levels plus 5 gap modals | VERIFIED | `## Esc Priority Chain` present; 5 numbered priority levels documented; GAPS block lists all 5: StateTransitionModal, AddProductForm, Delete-item modal, Start-return modal, RecipientPickerModal |
| 8 | Cross-Modal Interaction Map table exists | VERIFIED | `## Cross-Modal Interaction Map` present; 6 data rows + 1 header + 1 separator = 8 table lines (`grep "^|"` = 8 in section) |
| 9 | Known Pitfalls section with 6 numbered pitfalls | VERIFIED | `grep "### Pitfall [1-6]:"` = 6 matches; all have What/Why/How/Warning-signs format |

**Score:** 9/9 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `.planning/MODAL-STATE.md` | Complete modal state architecture reference, min 350 lines, contains "stateDiagram-v2" | VERIFIED | 863 lines; contains 9 `stateDiagram-v2` blocks; no placeholder text ("TBD" / "to be populated" = 0 matches) |

---

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `.planning/MODAL-STATE.md` | `.planning/RETRO-AGENT-FAILURE-PATTERNS.md` | C-3, D-4, F1, bac9584 cross-references | WIRED | Pattern `C-3\|D-4\|F1\|bac9584` matches 11 lines in MODAL-STATE.md; RETRO-AGENT-FAILURE-PATTERNS.md confirmed to exist and contain all 4 IDs |
| `.planning/MODAL-STATE.md` | `code_tips/CALLBACK_PIPELINE.md` | INV-2 references | WIRED | Pattern `INV-2` matches 7 lines in MODAL-STATE.md; CALLBACK_PIPELINE.md confirmed to contain `INV-2` section header |

---

### Data-Flow Trace (Level 4)

Not applicable — this is a documentation-only phase. No components render dynamic data. The artifact is a Markdown reference document.

---

### Behavioral Spot-Checks

Not applicable — documentation-only phase, no runnable entry points added.

---

### Requirements Coverage

Phase 20.5 declares `requirements: []` in PLAN frontmatter and ROADMAP.md states "Requirements: None (infrastructure phase)". No requirement IDs to trace.

REQUIREMENTS.md traceability table does not map any requirement to Phase 20.5 — consistent with the plan declaration. No orphaned requirements found.

---

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | — | — | — | — |

No placeholder text, no stubs, no TODO/FIXME comments found in MODAL-STATE.md.

---

### Human Verification Required

None. This is a documentation-only phase with no visual UI, runtime behavior, or external service integration to verify. The artifact is fully verifiable programmatically.

---

## Gaps Summary

No gaps. All 9 must-have truths pass verification. The document is substantive (863 lines), complete (9 modal sections, 9 state diagrams, 9 callback tables, Esc chain, cross-modal map, 6 pitfalls, 4 rules), and correctly cross-references live source files (RETRO-AGENT-FAILURE-PATTERNS.md and CALLBACK_PIPELINE.md).

The mandatory-read enforcement in `CLAUDE.md` was already in place before this phase and explicitly references MODAL-STATE.md — the "subsequent modal changes must update this doc" requirement is satisfied by the existing CLAUDE.md rule.

Commit `5072834` confirmed in git log: `docs(20.5-01): write complete MODAL-STATE.md architectural audit (9 modals)`.
