Observations addressed

• Observation 11 (journology/log.md): Shakedown fixes need persisted-data invariant checks → added: "Generated-data invariant checks" subsection — browser/unit success doesn't prove generated data quality; run a focused DB/API invariant check for the exact bug before closing the loop.
• Observation 14 (journology/log.md): Shakedown triage should treat optimistic flicker as a bug class → added: "Triage severity" subsection — optimistic flicker, stale cache, and revert-then-correct are first-class bugs; orientation affordances route to enhancements.
• Observation 15 (journology/log.md): Bug bashes need principle and enforcement capture → added: "Bug-bash immunity loop" subsection — capture root cause, principle, anti-pattern, current enforcement, and next enforcement candidate after each deterministic fix; promote repeating lessons via /learn.
• Observation 18 (journology/log.md): Product shakedown needs realistic scale and neglected surfaces → added: "Scale realism" subsection — keep a scenario backlog with large fixtures, full product surface coverage, and treat hidden single-entity assumptions as a first-class risk class.
