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

Goal Achievement

Observable Truths

#	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
