Game Move layout feedback analytics (`layout-feedback-analytics`)

Nightly aggregation of beta Game Move layout feedback events (LAYOUTFB# in DynamoDB) into private ops S3 for developer review and optional ML analysis.

Schedule

Daily 03:00 UTC (same window as records-rec-analytics).

Inputs

Live scan of abstract-play-{stage} for:

pk begins with LAYOUTFB#
sk >= watermark (with 5-minute overlap on incremental runs)

Event types: session_start, feedback, feedback_note, switch_to_classic, layout_switch.

Outputs (private ops S3)

Prefix: gamemove-layout/analytics/

Key	Description
`_state.json`	Watermark and dedupe state
`daily/YYYY-MM-DD.json`	UTC daily rollups including full note text in `notes[]`
`summary.json`	Latest window + rolling 7d/30d + `recentNotes` (up to 500)
`report/YYYY-MM-DD.md`	Human-readable summary with recent notes table

Note records include userHash (SHA-256 of Cognito sub from pk) for correlating multiple notes without raw user ids in reports. Full pk remains in DynamoDB until manual purge.

serverless invoke -f layout-feedback-analytics --stage dev
serverless invoke -f layout-feedback-analytics --stage prod

DynamoDB cleanup

Layout feedback items have no TTL. When the layout experiment concludes, delete LAYOUTFB#* items manually (one-off admin script or console).
