# Changelog

## V9

- Added a stricter LongCat full-inference gate.
- `full-inference-gated` is now the default LongCat implementation mode.
- Pi must either attempt the closest real inference path or produce `TECHNICAL_BLOCKERS.json` with evidence.
- The prompt now requires investigation of PyTorch SDPA, xformers, and HF Kernels flash-attn alternatives before declaring flash-attn blocking.
- Health-only validation is no longer reported as full inference success. The worker writes `inference_gate.json` and uses statuses such as `technical_blocker`, `health_only`, or `full_inference_candidate_health_passed`.


## V8

- Added robust LongCat Phase 8 behavior.
- Added HTTP `/health` validation before Gradio Client fallback.
- Added best-effort Space runtime/log diagnostics collection.
- Made hardware requests non-blocking and stop retrying on clear OAuth/auth 401 failures.
- Added recursive workspace upload so Pi-generated packages are not lost.
- Added `IMPLEMENTATION_MODE` for `full-inference-attempt` vs `safe-scaffold`.
- Switched default Pi model for LongCat runs to `Qwen/Qwen3-Coder-Next`.

## V7.3

- Fix Phase 7 worker syntax error in README metadata sanitizer by escaping embedded newlines in the generated worker script.
- Add a compile test for the extracted LongCat worker payload.


## v7.1

- Fixed Phase 7 UI launcher import: `launch_longcat_article_job` is now imported in `app.py`.
- Updated app description title to V7.

# Changelog

## v5.2

- Fix Phase 5 generated Space runtime dependency conflict by pinning `huggingface_hub>=0.34.0,<1.0.0` in target Space `requirements.txt`.
- Add a Pi instruction not to remove the `huggingface_hub` compatibility pin.


## V5

- Added Phase 5: `model_id` → model metadata analysis → Pi-adapted Gradio template → private Space → live API validation.
- Added `model_analysis.json` in the Bucket run folder.
- Increased default Job timeout to 30 minutes for model Space builds.

# Changelog

## V3

- Added Phase 3 Pi smoke test.
- Added `launch_pi_space_smoke_job` in `src/jobs.py`.
- Added `PI_SPACE_WORKER_SCRIPT` in `src/worker_payload.py`.
- Added a new Gradio tab to run Pi in a controlled HF Job.
- Pi modifies a minimal Gradio app before the worker creates a private Space.
- The live Gradio API validation now requires the Pi marker phrase.
- Pi output and traces are copied to the Bucket with best-effort redaction.

## V2.3

- Fixed Gradio API endpoint discovery.
- Avoided hardcoded `/predict` by using `client.view_api()` and fallbacks.

## V2.2

- Confirmed Gradio Client auth compatibility helper.
- Improved stdout logging for worker events.

## v4 — Pi gist recipe

- Added Phase 4 tab: Pi reads the HF Spaces Agent Quickstart gist and is asked to use the `hf` CLI to create/upload a private target Space.
- Added a new `pi_gist_recipe` worker payload.
- The wrapper still performs independent final validation through the live Gradio API before declaring success.
- Saved artifacts include `generated/GOAL.md`, optional `generated/PI_SUMMARY.md`, Pi logs, traces, API schema, and API test result.


## v5.1

- Fixed Phase 5 Pi invocation for Pi 0.73.x: use `pi -p` instead of removed `--prompt`.
- No architecture changes; Phase 5 remains wrapper-owned for Hub operations and live API validation.


## V6

- Added Phase 6 Runtime Recommender.
- Adds a no-build HF Job that analyzes model metadata, estimated file sizes, task/library, risks, and recommends CPU Basic / CPU Upgrade / ZeroGPU candidate / manual review.
- Writes `model_analysis.json`, `runtime_recommendation.json`, `state.json`, `events.jsonl`, and `report.md` to the Bucket.

## V7 — LongCat article reproduction pass

- Added Phase 7: LongCat article-style reproduction workflow.
- Adds a dedicated HF Job worker that asks Pi to adapt a LongCat Space scaffold using the HF Spaces gist.
- Creates the target Space privately.
- Requests `zero-a10g` first, with optional fixed GPU fallback (`l40sx1` by default).
- Validates a cheap `/health` endpoint live via `gradio_client` before marking success.
- Stores hardware attempts, model analysis, generated files, Pi logs, traces, and report in the bucket.

## V7.2

- Fixed Phase 7 README metadata upload failures by sanitizing `short_description` to <= 60 characters before upload.
- Moved Space hardware requests after file upload to avoid newly-created private Space propagation issues.
- Made hardware requests more tolerant by passing hardware strings directly and retrying with backoff.
- Added `read-billing` to OAuth scopes metadata to help with paid hardware/fallback checks.
