gz task envelope diagnose

Render TASK ID declarations from all four discovery channels side-by-side for an OBPI.

Usage

Bash
gz task envelope diagnose OBPI-0.0.64-04
gz task envelope diagnose OBPI-0.0.64-04 --json

Description

Shows per-channel TASK declarations for the named OBPI. When gz validate --task-envelope-coherence fails with a layer-drift (signature c) error, this command names which channel needs updating.

The four discovery channels are:

Channel Source
@advances (ch1) Python @advances decorator registrations
frontmatter tasks: (ch2) tasks: list[str] in OBPI brief frontmatter
commit trailers (ch3) Task: commit trailer in git history
ledger task_id (ch4) task_started events in .gzkit/ledger.jsonl

Layer-drift is reported when two or more non-empty channels declare different TASK IDs.

Flags

Flag Description
--json Machine-readable JSON output

1 Brief not found or legacy shape

Examples

Bash
# Table output showing per-channel TASK IDs
uv run gz task envelope diagnose OBPI-0.0.64-04

# JSON output for tooling
uv run gz task envelope diagnose OBPI-0.0.64-04 --json
