Pull request overview
Adds a new per-partner observation feature to expose “how long this partner agent has been stopped” (normalized and capped), aligning partner observations with the existing ego seconds_stopped signal.
Changes:
- Bump
PARTNER_FEATURESfrom 8 → 9 to reflect the expanded partner observation vector. - Extend
write_partner_obsto appendfminf(1.0f, other->seconds_stopped / MAX_STOPPED_SECONDS)as the 9th partner feature.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
The interactive obs viewer hardcoded the partner block stride as 8, so with PARTNER_FEATURES=9 it mis-parsed partners and shifted every subsequent obs block (lanes/boundaries/traffic). Add partner_features to the replay header and use H.partner_features (mirroring how target_features is already handled). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Update the notebooks with the new partners features
The smoke golden is only bit-reproducible inside the QEMU/Haswell smoke image, so it cannot be regenerated on an arbitrary dev box. This adds a push-triggered (marker-gated) CI job that builds the image, runs the train smoke test with SMOKE_UPDATE_GOLDEN=1, uploads the result as an artifact, and commits it back to the branch.

- Regenerate smoke golden in the pinned QEMU image (via CI workflow); it now reflects the 9th partner feature plus the obs/reward_components metrics the current pipeline logs. - Mark partner seconds_stopped obs as a temporary hack in drive.h. - 05_inference.ipynb: add seconds_stopped to partner_labels, drive the per-feature loop off len(partner_labels) instead of a literal 8, and fix stale shape comments + the markdown obs spec. Also corrects a pre-existing length/width label swap to match the C write order. - Workflow: git add -f the golden (tests/smoke_tests/data is gitignored).

The partner heatmap sets xticks to range(env.partner_features) (now 9) but xticklabels to partner_labels; without the 9th label the ticks/labels mismatch. Append seconds_stopped to match. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

partner observation block.
