Verdict

Status: APPROVED_FOR_AGENT_B3F1C_A_SHAPE_PROBE_COMPILE_WITH_GPT_PATCHES

Opus direction is accepted: B3-F1c must be shape-probe-first and two-pass. B3-F1c-a may run as read-only + compile-only after the GPT patches below. B3-F1c-b execution remains disallowed until GPT reviews compiled artifacts.

GPT patches applied

1. Reworded completion language: B3-F is not complete from this design alone. It may be marked complete only after B3-F1c execution and GPT review.
2. Removed implicit extension-install path: pg_cron available but not installed is BLOCKED_FOR_EXTENSION_DECISION; no extension installation is allowed in B3-F1c-a.
3. Manual Agent/human call is documented only as emergency fallback and does not satisfy automatic coverage.
4. Hard boundaries now require read-only SELECTs only and existence checks before querying candidate tables such as dot_tools or directus_flows.
5. Directus Flows / DOT scheduler probes must first confirm table and column existence; no schema assumptions.
6. system_health_checks summary write logic must be compiled only after shape is proven live; exact columns must be derived from live shape.
7. Scheduler cadence must be configuration/policy, not a hardcoded cron expression. Any example cadence is only a candidate for later approval.
8. Rollback wording now drops only B3-F1c-created artifacts; it must not touch B3-F1b, B3-A, dot_config policy, system_issues data, or system_health_checks history.
9. Final fields now make clear:
   • pg_cron_extension_install_allowed=false
   • external_tool_install_allowed=false
   • manual_fallback_counts_as_automatic=false

PG-first / PG-native / PG-driven assessment

Approved for B3-F1c-a because:

• the scheduler mechanism will be selected from live probe evidence, not assumptions;
• full-scan logic reuses reviewed PG SQL;
• sibling scope continues to be read from dot_config;
• no runtime sibling collection list should be embedded;
• no hardcoded OIDs or snapshot counts should be used as gates;
• function/scheduler artifacts are compiled before execution.

Remaining caveat

B3-F1c must not assume pg_cron. If pg_cron is absent, do not install it in this path. Opus/Agent must either find an existing PG-native scheduler/health-check mechanism or report BLOCKED_FOR_SCHEDULER_DECISION.

Execution approval

Agent may run B3-F1c-a only:

• read-only scheduler/shape probe;
• compile SQL artifacts;
• write report/artifacts to KB;
• no PG DDL/DML execution.

Use prompt:

• knowledge/dev/laws/dieu44-trien-khai/prompts/p3d-birth-system-b3f1c-full-scan-automation-shape-probe-prompt-DRAFT.md revision 7 or latest.

Still forbidden

• No B3-F1c-b execution.
• No CREATE FUNCTION.
• No scheduler creation.
• No CREATE EXTENSION.
• No system_issues/system_health_checks writes.
• No external tool installation.
• No hard gate.
• No Phase 5C2.
• No UI cutover.

Required Agent report
