E7 D4 Failed Attempt Log — 2026-04-27

Actor: Opus 4.6 (Claude.ai) Gateway: Directus MCP Prompt: E7 D4 Execution Gate v0.1

Pre-flight

#	Check	Result	Status
1	DOT-TAC-* = 0	0 items	PASS
2	API healthy	responding	PASS
3	Payload matches E7 v0.1	yes	PASS

Execution

#	Code	HTTP	Error	Status
1	DOT-TAC-SCHEMA-ENSURE	400	Invalid foreign key for field "domain" — "tac.infrastructure" not in vocabulary	FAIL

Partial State

0 DOT-TAC- rows created.* No cleanup needed.

Root Cause

D1–D3 dry-run validated payload logic (paired dots, cron, P8 cross-check) but did NOT validate dot_tools.domain FK constraint against production vocabulary. 19 payloads used tac.* domain values that don't exist.

Remediation

Option 2: remap to existing domain vocabulary values. See E7 v0.2.

Verdict: FAIL — FK domain blocker. Remediated in v0.2.
