Migrate to seahaven-prod: deploy role, backfill tooling, account-portability fixes (#125)
* feat(migration): prepare stacks and tooling for the seahaven-prod account move

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.

* fix(migration): verify backup AVAILABLE pre-truncate; document wildcard risk acceptance (cross-review FIX/NIT)

* refactor(migration): drop cross-account read grants (slack-bot decommissioned); harden backfill + deploy role

seahaven-slack-bot was decommissioned 2026-07-23 (stack DELETE_IN_PROGRESS,
consumer Lambdas gone); its successor sh-mcp is undeployed and uses
same-account DynamoDB access. So no live consumer reads these tables
cross-account. Per Adam's call, drop the cross-account grants entirely and
re-add correctly-scoped ones if/when sh-mcp deploys to a different account.

- Remove the four table resource policies + make_slack_bot_read_policy helper
  + its constants (cdk/common.py, po_stack.py, wo_stack.py) and the helper's
  unit test. Both stacks synth with zero table ResourcePolicy.
- scripts/migrate_tables.py hardening (fixes from the sh-security-review
  fan-out on the destructive backfill tool):
  * validate --cutoff strictly (parse ISO-8601, require aware UTC, re-emit
    canonical second-precision form) so a malformed cutoff can't silently
    copy dual-window rows or drop history;
  * reject `copy --all` up front (must run tables individually, in order,
    with the stream-drain wait) instead of writing three tables then erroring;
  * truncate backup gate now also checks recency (<1h) and TableId, not just
    status+name;
  * verify requires --cutoff whenever a cutoff table is in scope (else it
    false-flags dual-window rows as MISSING);
  * sticky-cancel is now PREVENTED copy-side (a non-Cancelled source item
    never overwrites a dest-Cancelled PO), and the verify comment no longer
    overstates what its source-side scan covers;
  * spot-check all modes (truncate_load keys are verbatim, so key-existence
    is sound there too).
- Deploy role: scope cloudformation:DescribeStacks to this repo's stacks +
  CDKToolkit (was Resource:*, disclosed all tenant stacks in the shared prod
  account); add a drift check warning on unexpected role policies and drop the
  dead SMOKE_POLICY_NAME var; document the shared-account bootstrap-role
  accepted risk in the deploy-role README.

* docs(deploy-role): fold in cross-review NITs (DescribeStacks maintenance note, warn-only drift rationale)

* ci: update workflow to use new workflow tag (ruff versioning fix)

* fix(migration): address Open SWE review findings on migrate_tables.py

- Validate the truncate backup on dry-run as well as --execute so a
  missing/stale/wrong-incarnation --backup-arn surfaces on the rehearsal
  run (finding f_24a48b8900).
- Assert configured keys match the live key schema of both tables before
  any key projection, turning config/schema drift into a descriptive
  abort instead of a mid-backfill KeyError (finding f_cb6b5a6c59).
- Clarify why key-existence spot-checks are sound for WorkOrderComments:
  the copy Puts source items verbatim and the sample uses the same
  cutoff filter, so per-account comment_id divergence never enters the
  check (finding f_390b7d6c3b is a false positive; comment hardened).

# Creates / updates the GitHub Actions OIDC deploy role

# Part of the mgmt -> seahaven-prod migration. The mgmt-account role of the

#
# GATE - DO NOT EXECUTE until BOTH of the following have passed on these
# exact artifact files:
# 1. GPT-4.1 cross-family review (IAM policy / trust-policy change) via
# cross_review.py in the security-review repo.
# 2. /sh-security-review (deep agentic pass - IaC/IAM is a gated surface).
#
# The SmokeInvokeLambda statement is REQUIRED, not optional: deploy.yaml runs
# scripts/post-deploy-smoke.sh under this role's session (not the assumed
# cdk-* roles), and the smoke gate fails closed without lambda:InvokeFunction
# on exactly the two email-processor function ARNs. The mgmt-era equivalent
# of this policy was applied out-of-band and documented nowhere; these
# artifacts are the fix for that debt.
#
# Resolved facts (verified 2026-07-23, read-only):
# Account : 011934824531 (seahaven-prod)
# Region : us-east-1
