Phase 1 of the mgmt (328440206208) -> seahaven-prod (011934824531)
migration. No behavior change in-account; everything here is additive or
account-portability hygiene:
- infra/deploy-role/: reviewed OIDC deploy-role artifacts for prod
(trust main-only, cdk-hnb659fds-* AssumeRole, smoke-invoke-lambda scoped
to exactly the two email-processor fn ARNs). Codifies the previously
out-of-band smoke-invoke grant.
- Table resource policies: make_slack_bot_read_policy in cdk/common.py,
applied to purchase-orders, verified-sites, WorkOrders,
WorkOrderComments (NOT pending-site-review; no bot consumer). Grants the
mgmt-resident seahaven-slack-bot roles read-only cross-account access
post-move (bot-side identity grants land in the slack-bot repo).
- scripts/migrate_tables.py: dry-run-default backfill tool implementing
the plan's per-table semantics (superset overwrite, ingested_at cutoff
for WorkOrderComments, backup-gated truncate-and-load for the two
site tables) plus a verify subcommand (count parity, spot checks,
sticky-Cancelled drift check).
- tests/test_resource_policy_helper.py: statement-shape unit tests +
static pins that exactly the four bot-read tables carry the policy.
- Account-literal fixes: account-agnostic fixture bucket in
test_reprocess_contract; runbook/README/po-template-parser account
references updated to prod with historical mgmt notes; README gains the
account-prerequisites list (imported-by-name dependencies).
deploy.yaml is deliberately unchanged (push-to-main auto-deploy kept).
Merge is held until migration Phase 0 completes; flipping the
AWS_DEPLOY_ROLE_ARN repo secret and merging this PR IS the first prod
deploy.
