K1 Single-Skill Directness Control

This material intentionally co-locates the two K2 components. Execute the embedded components in their original order. Any reference to an embedded component is internal sequencing, not a request to load a separate skill. This is a structural directness control and does not preserve the source cross-skill authority boundary.

Embedded component: pedestrian-traffic-counting-wob-k2-prep-producer

Combined WOB Workflow Stage

Execute component roles below in order. A component instruction that routes to another component in this same skill is an internal checkpoint: continue directly to the next component and do not read a separate skill. Do not reinterpret a sealed non-self binding or replace the packet consumer's responsibility.

Combined role: pedestrian-traffic-counting-intake-checkpoint

Stage 1 — Pedestrian checkpoint

Run exactly:

python3 /root/.codex/skills/pedestrian-traffic-counting-wob-k1-monolith/scripts/build_checkpoint.py

This helper is the only authority for artifacts/pedestrian-traffic-counting/workbook-checkpoint.json. Do not count videos or create count.xlsx here. Do not hand-write a checkpoint. On success, stop and proceed to pedestrian-traffic-counting-resolved-workbook-state.

Combined role: pedestrian-traffic-counting-resolved-workbook-state

Stage 2 — Pedestrian resolved state

Require the checkpoint from stage 1. Run exactly:

python3 /root/.codex/skills/pedestrian-traffic-counting-wob-k1-monolith/scripts/build_resolved_workbook_state.py

The helper performs the task-native video analysis and writes artifacts/pedestrian-traffic-counting/resolved-workbook-state.json. Do not invent counts, write the workbook, build a packet, or modify its state manually. On success, stop and proceed to pedestrian-traffic-counting-count-packet.

Count-Study Continuation

After this stage's local outputs are complete, read pedestrian-traffic-counting-wob-k2-consumer-writer before continuing. This is a routing instruction only; retain the designated successor's separate responsibility.

Embedded component: pedestrian-traffic-counting-wob-k2-consumer-writer

Combined WOB Workflow Stage

Execute component roles below in order. A component instruction that routes to another component in this same skill is an internal checkpoint: continue directly to the next component and do not read a separate skill. Do not reinterpret a sealed non-self binding or replace the packet consumer's responsibility.

Combined role: pedestrian-traffic-counting-count-packet

Stage 3 — Pedestrian packet

Require artifacts/pedestrian-traffic-counting/resolved-workbook-state.json from stage 2. Run exactly:

python3 /root/.codex/skills/pedestrian-traffic-counting-wob-k1-monolith/scripts/build_packet.py

This stage may read only the resolved state. It must not revisit videos, recount pedestrians, or write /app/video/count.xlsx. Do not hand-write the packet. On success, stop and proceed to pedestrian-traffic-counting-count-writer.

Combined role: pedestrian-traffic-counting-count-writer

Stage 4 — Pedestrian workbook writer

Require artifacts/pedestrian-traffic-counting/count-write-packet.json from stage 3. Run exactly:

python3 /root/.codex/skills/pedestrian-traffic-counting-wob-k1-monolith/scripts/write_workbook.py \
  artifacts/pedestrian-traffic-counting/count-write-packet.json \
  artifacts/pedestrian-traffic-counting/count-write-receipt.json

This stage may consume only the packet. It must not inspect videos, recount values, or revise the packet. The helper writes /app/video/count.xlsx and the receipt; finish after it succeeds.
