## Problem
On 4XL and larger compute sizes, Supabase disk IO is sustained rather
than burst-budget based. Baseline equals max, so there is no extra burst
balance to track (the instance can still be throttled if it hits its
configured IOPS or throughput limit, but that is unrelated to a burst
credit pool). The "Disk IO Burst Balance" / "Disk IO % Remaining" /
"Disk IO % Consumed" charts in custom reports are therefore meaningless
on 4XL+, yet they are currently still offered in the picker and rendered
as empty/misleading charts.
Custom reports persist their layout, so a report created when a project
was on a smaller compute and later upgraded to 4XL+ can still contain a
saved burst chart that we need to handle gracefully.
## Fix
- Add a shared \`hasBurstableIO(infra_compute_size)\` helper in
\`DiskManagement.utils.ts\` (replaces the local
\`BURSTABLE_IO_VARIANTS\` set previously defined inline in
\`database-charts.ts\`).
- Filter \`disk_io_budget\` and \`disk_io_consumption\` out of the
custom report chart picker (\`MetricOptions\`) when the project is on a
non-burstable compute size.
- In \`ReportBlock\`, detect saved burst charts on a 4XL+ project and
render a new \`UnavailableChartBlock\` that explains the chart no longer
applies and can be removed.
- The database observability burst balance chart already gated on
\`hasBurstableIO\`; updated to use the shared helper.
- Infrastructure activity page already has equivalent handling via the
dedicated-IO admonition, so no change needed there.
Linear: FDBKPRI-1404
## Test plan
- [ ] On a project below 4XL, the custom report picker still lists "Disk
IO % Remaining" and "Disk IO % Consumed", and they render normally
- [ ] On a 4XL+ project, neither metric appears in the picker
- [ ] Open an existing custom report that contains a saved burst balance
chart on a 4XL+ project, and confirm the placeholder block renders with
a clear explanation and a remove action
- [ ] Database observability page on 4XL+: the burst balance chart
remains hidden, all other charts render

## Summary by CodeRabbit
* **New Features**
* Disk IO metrics are now filtered based on your project’s compute size
so only relevant charts appear.
* Metrics tied to burstable IO are hidden when the current instance does
not support burstable IO; deprecated metrics remain excluded.
* When a disk IO chart isn’t available for your instance, the UI shows
an explanatory unavailable-chart block with text about burst-balance
limits for very large instances and optional actions to remove the
unavailable chart.

- Fix gp3 max-IOPS calculation: was `3000 × size`, is slightly more complicated. The old multiplier let Studio accept IOPS values that the platform API would reject.
- Block IOPS/throughput edits when the disk is smaller than the minimum required for custom IOPS (6 GB for gp3). Previously, a throughput-only change on a 2 GB disk would still ship `provisionedIOPS: 3000` in the payload and get rejected with: `Invalid IOPS value for gp3 volume 3000. Minimum is 3000. Max is 500 IOPS per GB or 16,000, whichever is lower.`
- Show a NoticeBar prompting users to grow the disk first, with a one-click button to bump it to the minimum (mirrors the existing "Change to LARGE Compute" pattern).
- Surface the helpful "Larger Disk size required" message for all disk sizes instead of a cryptic "Invalid IOPS value due to invalid disk size" fallback for disks < 8 GB.
https://linear.app/supabase/issue/FE-2226/fix-incorrect-baseline-and-max-iopsthroughput-values
- Centralized compute/disk limits in
packages/shared-data/compute-disk-limits.ts (MB/s, baseline+max
IOPS/throughput) and re-exported from shared-data.
- Hooked Docs compute/disk table into shared data, converted docs
text/table to MB/s baseline/max.
- Removed duplicated compute IOPS/throughput constants from Studio,
Studio now imports shared data.
- Updated Studio disk schema: compute-aware MAX IOPS/throughput
validation (MB/s), defaults computeSize to ci_micro, and gp3/io2 checks
use compute caps.
- Clarified disk update mutation to send throughput as MB/s despite
backend throughput_mbps field name.
- Added tests for compute-size mappings and IOPS helper logic.
- Added Infra ownership for shared compute/disk data in CODEOWNERS.
- Locked zod version via catalog and added zod dep to shared-data.

## Summary by CodeRabbit
* **New Features**
* Added a reusable Compute Disk Limits table and centralized compute
disk limits dataset for dynamic display.
* **Documentation**
* Replaced static per-size tables with a component-driven MB/s view;
clarified baseline vs. burst behavior and updated guides and
troubleshooting.
* **Bug Fixes**
* Validation and UI guidance now honor compute-size limits for IOPS and
throughput.
* **Tests**
* Expanded unit tests for sizing, mappings, and edge cases.
* **Chores**
* Published shared-data exports, added a validation schema, pinned a
dependency, and added ownership entries.
