docs: say what permissions a summary-schedule deploy needs - #90
Conversation
`docs/log-table/` and `docs/query-workgroup/` each say what a narrowed CloudFormation execution role has to hold, and `docs/summary-schedule/` said nothing while creating more kinds of resource than either. A deploy of the defaults writes ten schedules, a function, a log group, two roles and a bucket, so the page now lists `scheduler:`, `lambda:`, `logs:`, `iam:` and `s3:` with the actions each one takes. `scheduler:` is the one an account misses, since `lambda:` is usually allowed for other reasons already. The job's own role sends `athena:`, `glue:`, `s3:` and `ssm:GetParameter` when it runs, and a deploy role sends none of them. That is its own section, because a service control policy denies an unlisted prefix whichever role sent the call, and an account that allows only the deploy list deploys cleanly and fails on the first schedule that fires. The resource counts come from synthesising the construct with its defaults. Nothing here has been deployed under a role narrower than `AdministratorAccess`, and the page says so the way its neighbours do.

📝 WalkthroughWalkthroughThe documentation now describes scoped deployment-role permissions and scheduled-run permissions for summary schedules. It also documents deployment versus runtime failures and manual creation of the visitor-salt SecureString parameter. ChangesSummary schedule permissions
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🟡 Moderate · up to The documentation currently recommends permission guidance that can cause deployments to fail, grant access beyond the intended schedules and resources, and omit required S3 actions or object scopes.

In `@docs/summary-schedule/README.md`:
- Around line 294-303: Split logs:DescribeLogGroups out of the PolicyStatement
identified by sid "TheRainlyticsSummaryLogs" into a separate statement with
Resource "*"; keep logs:CreateLogGroup, logs:PutRetentionPolicy, and
logs:DeleteLogGroup in the existing log-group-scoped statement.
- Around line 269-277: Update the schedule policy documentation around the
schedulePrefix resource ARN to require a deployment-unique prefix, or explicitly
document that the policy is shared when prefixes can collide. Clarify that
CfnSchedule names use this prefix and that matching default-group schedules may
be updated or deleted, so the chosen prefix must not overlap another deployment.
- Around line 291-302: Update the PolicyStatement resources for Lambda and
CloudWatch Logs to use deployment-specific names or synthesized-name patterns
instead of broad function:* and log-group:* wildcards. Preserve
logs:DescribeLogGroups with a * resource, while scoping the remaining log
actions and Lambda permissions to resources created by this deployment.
- Around line 358-360: Update the S3 permissions section in the README to
replace the broad s3 entries with the exact generated actions and resource
scopes: distinguish log-bucket bucket ARN permissions from object ARN read
permissions, enumerate the Athena results bucket grantReadWrite actions
including applicable s3:List*, s3:PutObject*, and s3:Abort* permissions, and
document the summaries bucket grantPut object scope.

Review points on the section this branch added.
`logs:DescribeLogGroups` has no resource type in IAM, so a statement
naming a log group authorises it for nothing. It gets its own statement
on `*`, and `CreateLogGroup`, `PutRetentionPolicy` and `DeleteLogGroup`
stay scoped to the group.
The function and the log group are scoped to `${stackName}-*` the way
the roles already were. CloudFormation names all four after the stack
and the logical id, and the truncation trap on the log bucket page
covers each of them.
The schedule wildcard matches on the prefix alone, so a second
deployment calling itself `rainlytics-docs-` sits inside a statement
quoting `rainlytics-*`. The page now says to pick a prefix that is not
the opening of another one's.
The running job's `s3:` line is replaced by the actions CDK's
`grantReadWrite` and `grantPut` produce, read off a synthesised
template rather than inferred.

docs/summary-schedule/now carries the permissions section its two neighbours carry. A deploy of the defaults writes ten schedules, one function, one log group, two roles and a bucket, and the page lists thescheduler:,lambda:,logs:,iam:ands3:actions that takes, withscheduler:called out as the prefix an account is likely to miss. What the job's own role sends when it runs (athena:,glue:,s3:andssm:GetParameter) is a separate section, because a deploy role sends none of those and a service control policy has to allow them anyway. The resource counts come from synthesising the construct, the actions are inferred from what it creates, and the page says so the waydocs/log-table/anddocs/query-workgroup/do. It also points at theSecureStringparameter nothing in the template creates.Resolves #86
