- Ring scheduler: use DynamoDBCrudPolicy (resolve_shift needs Query)
- Button pickup: update 3CX for active shift type, not just night
- Pick/drop/swap commands: only update 3CX when shift type is active
- Swap command: add missing past-date guard
- add_roster_entry: reject if extension already exists
- Apply ruff formatting
- Store schedule message timestamp in DynamoDB (SCHEDULE_POST record)
- Delete previous week's schedule post before posting the new one
- Live-update the schedule post via chat_update after any
pick/drop/swap/button-pickup so it always reflects current state
- Slack bot token and signing secret now read from Secrets Manager
- 3CX credentials (domain, client-id, client-secret) moved to
Secrets Manager under afterhours-shift-manager/3cx-* prefix
- Channel ID is now a non-secret CloudFormation parameter (ShiftChannel)
- Add shared secrets.py helper for Secrets Manager reads
- Remove SSM and KMS IAM policies, add secretsmanager:GetSecretValue
Move from flat src/ to per-function directories:
- src/slack-bot/ — Slack Bolt Lambda handler
- src/weekly-post/ — Monday schedule + pay post
- src/roster-sync/ — Daily 3CX roster sync
- src/shared/ — Lambda Layer with schedule, blocks, three_cx_client
Each function has its own requirements.txt and CodeUri. Shared
modules are deployed as a SAM Layer (afterhours-shared) importable
as `from shared.X import Y`.
