Changed the pastebin tutorial so it now starts skeletal: no prebuilt Flask behavior, no pre-generated task tests, and .gitkeep placeholders under templates/ and tests/. The new pipeline in nightshift/project_templates/tutorial-pastebin/nightshift.yaml:1 now runs:
plan -> semantic_context -> context -> write_tests -> review_tests -> implement -> pytest -> review
────────────────────────────────────────────────────
Added nightshift/project_templates/tutorial-pastebin/.nightshift/agents/test-writer.md:1, tightened the planner/implementer/reviewer/debugger prompts, mirrored the pipeline docs/
example, and raised default retries to 6 for the basic starter plus pastebin.
I also fixed the retry policy issue in nightshift/escalation.py:17 and nightshift/pipeline.py:251: configured repeated-failure thresholds are now respected instead of hard-stopping in nightshift/project_templates/tutorial-pastebin/
early after three same-stage/same-cause failures. Non-implementation file_writer stages now get stage-specific retry artifacts so test generation does not collide with implementation
repair artifacts
