# Phase 14: Multi-Signer Schema Verification Report
|
||
|
|
|
||
|
|
**Phase Goal:** The database schema is ready for multi-signer documents — signers are first-class records on documents, tokens carry signer identity, and the completion guard column prevents race conditions — with zero breakage to existing single-signer documents
|
||
|
|
**Verified:** 2026-04-03
|
||
|
|
**Status:** passed
|
||
|
|
**Re-verification:** No — initial verification

|
| # | Truth | Status | Evidence |
|
||
|
|
| --- | ---------------------------------------------------------------------------------------------- | ---------- | ---------------------------------------------------------------------------------------------- |
|
||
|
|
| 1 | Existing single-signer documents continue to prepare, send, and sign with zero code changes | VERIFIED | All 3 new columns are nullable; `signerEmail?` on interface is optional; no existing column or function changed |
|
||
|
|
| 2 | `SignatureFieldData` has an optional `signerEmail` field for field ownership routing | VERIFIED | Line 21 of schema.ts: `signerEmail?: string; // Optional — absent = legacy single-signer or agent-owned field` |
|
||
|
|
| 3 | `signingTokens` has a nullable `signerEmail` column for per-signer token identity | VERIFIED | Line 140 of schema.ts: `signerEmail: text('signer_email'),` (no `.notNull()`) |
|
||
|
|
| 4 | `documents` has a `signers` JSONB column typed as `{ email: string; color: string }[]` | VERIFIED | Lines 113-114 of schema.ts: `signers: jsonb("signers").$type<DocumentSigner[]>()` backed by `DocumentSigner { email: string; color: string }` interface at lines 87-90 |
|
||
|
|
| 5 | `documents` has a nullable `completionTriggeredAt` timestamp column for race-safe completion | VERIFIED | Lines 114-115 of schema.ts: `completionTriggeredAt: timestamp("completion_triggered_at"),` (no `.notNull()`) |
|
||
|
|
| 6 | Drizzle migration 0010 applies cleanly with no data loss | VERIFIED | `0010_sharp_archangel.sql` contains exactly 3 additive `ALTER TABLE...ADD COLUMN` statements, no DROPs, no ALTER TYPEs, no backfills; journal entry idx 10 present |
|
||
|
|
|
||
|
|
**Score:** 6/6 truths verified

### Required Artifacts
|
||
|
|
|
||
|
|
| Artifact | Expected | Status | Details |
|
||
|
|
| -------------------------------------------------------------- | ------------------------------- | ---------- | ------------------------------------------------------------------------------------------- |
|
||
|
|
| `teressa-copeland-homes/src/lib/db/schema.ts` | Multi-signer schema additions | VERIFIED | Contains `signerEmail?` on interface (line 21), `getSignerEmail` helper (lines 49-51), `DocumentSigner` interface (lines 87-90), `documents.signers` (line 113), `documents.completionTriggeredAt` (line 115), `signingTokens.signerEmail` (line 140) |
|
||
|
|
| `teressa-copeland-homes/drizzle/0010_sharp_archangel.sql` | Drizzle-generated migration SQL | VERIFIED | File exists; contains `signer_email`, `signers`, and `completion_triggered_at`; 3 lines total, all ADD COLUMN |
|
||
|
|
|
||
|
|
### Key Link Verification
|
||
|
|
|
||
|
|
| From | To | Via | Status | Details |
|
||
|
|
| --------------------- | ------------------------------- | ----------------- | -------- | ---------------------------------------------------------------------------------------------- |
|
||
|
|
| `schema.ts` | `0010_sharp_archangel.sql` | `drizzle-kit generate` | VERIFIED | Migration SQL matches schema.ts additions exactly: `ALTER TABLE "signing_tokens" ADD COLUMN "signer_email" text`, `ALTER TABLE "documents" ADD COLUMN "signers" jsonb`, `ALTER TABLE "documents" ADD COLUMN "completion_triggered_at" timestamp` |
|
||
|
|
| `drizzle/meta/_journal.json` | migration 0010 | journal entry | VERIFIED | Entry idx 10 tag `0010_sharp_archangel` present in `_journal.json`; `0010_snapshot.json` also exists |
|
||
|
|
|
||
|
|
### Data-Flow Trace (Level 4)
|
||
|
|
|
||
|
|
Not applicable. Phase 14 is schema-only — no components, no API endpoints, and no data-rendering code paths were added or modified. The only artifacts are type definitions and a SQL migration.
|
||
|
|
|
||
|
|
### Behavioral Spot-Checks
|
||
|
|
|
||
|
|
| Behavior | Command | Result | Status |
|
||
|
|
| -------------------------------- | ---------------------------------------------------------- | ------------ | ------- |
|
||
|
|
| TypeScript compiles cleanly | `npx tsc --noEmit` | exit 0, no output | PASS |
|
||
|
|
| `signerEmail` appears 6 times in schema.ts | `grep -c signerEmail src/lib/db/schema.ts` | 6 | PASS |
|
||
|
|
| Migration contains no DROP statements | `grep -i DROP drizzle/0010_sharp_archangel.sql` | no matches | PASS |
|
||
|
|
| Migration contains no audit_event_type changes | `grep audit_event_type drizzle/0010_sharp_archangel.sql` | no matches | PASS |
|
||
|
|
| `Partially` not added to documentStatusEnum | `grep Partially src/lib/db/schema.ts` | no matches | PASS |
|

### Requirements Coverage
|
||
|
|
|
||
|
|
| Requirement | Source Plan | Description | Status | Evidence |
|
||
|
|
| ----------- | ----------- | ---------------------------------------------------------------------- | ---------- | ---------------------------------------------------------------------------------------------------------- |
|
||
|
|
| MSIGN-08 | 14-01-PLAN | Server enforces field ownership — a signer can only submit fields assigned to them | SATISFIED (foundation) | Phase 14 scope is schema-only per CONTEXT.md D-06. MSIGN-08 enforcement requires `signerEmail` on `SignatureFieldData` and `signingTokens` — both columns now exist. Enforcement handler logic is Phase 15 scope. Traceability table marks MSIGN-08 as Complete at Phase 14. |
|
||
|
|
|
||
|
|
**MSIGN-08 scope note:** The requirement reads "server enforces field ownership." Phase 14 establishes the data columns that make enforcement possible (`signerEmail` on `SignatureFieldData` interface for field-level ownership, `signerEmail` on `signingTokens` for identity binding). The actual enforcement handler (Phase 15) reads these columns to reject mismatched submissions. Phase 14 as defined in CONTEXT.md decision D-06 explicitly defers the sign handler rewrite to Phase 15 — this boundary is intentional and reflected in the traceability table marking MSIGN-08 as Complete for Phase 14.

### Anti-Patterns Found
|
||
|
|
|

|
|
| File | Line | Pattern | Severity | Impact |
|

| ---- | ---- | ------- | -------- | ------ |
|

|
|
| — | — | None found | — | — |
|
||
|
|
|
||
|
|
No TODO/FIXME comments, no placeholder stubs, no empty implementations. The schema changes are complete and substantive. No files outside `schema.ts` and `drizzle/` were modified.
|
||
|
|
|
||
|
|
### Human Verification Required
|
||
|
|
|
||
|
|
**1. Migration applied to Neon production database**
|
||
|
|
|
||
|
|
**Test:** Connect to the Neon production database and run `\d signing_tokens` and `\d documents` to confirm the three columns exist in the live schema.
|
||
|
|
**Expected:** `signing_tokens` has a `signer_email` text column (nullable); `documents` has `signers` jsonb (nullable) and `completion_triggered_at` timestamp (nullable).
|
||
|
|
**Why human:** Cannot verify live database state programmatically from this environment. The SUMMARY.md reports the migration applied successfully; this cannot be confirmed without a live DB connection.
|
||
|
|
|
||
|
|
### Gaps Summary
|
||
|
|
|
||
|
|
No gaps. All 6 must-haves are fully verified:
|
||
|
|
|
||
|
|
- `SignatureFieldData.signerEmail?` is in schema.ts at line 21
|
||
|
|
- `getSignerEmail(field, fallbackEmail)` helper is in schema.ts at lines 49-51
|
||
|
|
- `DocumentSigner { email, color }` interface is in schema.ts at lines 87-90
|
||
|
|
- `documents.signers` JSONB column is in schema.ts at line 113 and migration line 1
|
||
|
|
- `documents.completionTriggeredAt` timestamp column is in schema.ts at line 115 and migration line 2
|
||
|
|
- `signingTokens.signerEmail` text column is in schema.ts at line 140 and migration line 3
|
||
|
|
- Migration is strictly additive (3 ADD COLUMN statements, no drops, no type changes)
|
||
|
|
- TypeScript compiles cleanly (exit 0)
|
||
|
|
- All existing single-signer code paths are unaffected (all additions nullable/optional)
|
||
|
|
- Committed at hashes c658f13 and 3639491
