Capture three rollout-process lessons in BACKLOG

[Gimpleberry]

Captures three patch-script-template improvements surfaced during the validate.sh / CI lint parity rollout (PR #3):

1. Sandbox must include kai.shared so Tenet 1 violations in generated Python files surface during pre-delivery QC.
2. Patch scripts that create Python files should run ruff format on them as a final edit step.
3. Parity-test pattern generalizes per CI workflow with a local mirror; defer meta-test until 2nd pair exists.

All three are PRIORITY: triggered by next applicable patch, not by clock time.

Summary

Captures three patch-script-template improvements surfaced during PR #3 (validate.sh / CI lint parity rollout). Pure documentation change, no functional impact.

Changes

• path/to/file.py — what changed and why

Linked work

Follow-up to PR #3. No BACKLOG item closed (this PR adds to BACKLOG rather than completing an item).

• Closes #
• Backlog: <name of phase + item>
• ADR: (if this introduces an architectural change)

Validation checklist (Tenet 5)

• 1. Lint — ruff check + format --check clean on every modified file
• 2. shared.py uniqueness — no symbol duplicated outside shared.py
• 3. Encoding sweep — no non-ASCII in Python source
• 4. Plugin registry — every entry has start()/stop()
• 5. Import chain — no circular imports
• 6. Lifecycle — main.py --check passes
• 7. Docs present — README/CHANGELOG/DECISIONS/BACKLOG/PROJECT_KNOWLEDGE
• 8. Config valid — kai validate-taxonomy passes
• 9. Unit tests — all green
• 10. Integration boot — main.py --boot-order works

scripts/validate.sh summary:

Passed: __ / 10

Documentation updated

• CHANGELOG.md entry added under appropriate version
• PROJECT_KNOWLEDGE.txt updated if architecture or folder map changed
• DECISIONS.md ADR added if this is a non-trivial architectural choice
• BACKLOG.md updated (phase items moved/completed/added)
• In-app Help section added/updated if user-facing behavior changed

Risk + rollback plan

Pure documentation. git revert is a clean undo. No code, schema, or behavior changes.
