Doc Specialist — Technical Review
|
| Section | Verdict |
|---|---|
| Architecture (control plane → Neon branch, EC2 SG per tenant) | ✅ Correct |
| Neon branch-per-tenant isolation model | ✅ Correct |
| Security group: inbound :443 from platform only | ✅ Correct |
POST /cp/orgs request/response shape |
✅ Correct |
| Async provisioning + polling pattern | ✅ Correct |
| Tenant workspace creation via org-scoped key | ✅ Correct |
| Fleet inspection via control plane | ✅ Correct |
| Suspend vs. hard-delete behavior | ✅ Correct |
| Security model table | ✅ Correct |
❌ Bug: HTTP status code (line ~175)
The tutorial states that when a tenant hits their workspace limit, POST /workspaces returns 402 Payment Required.
Problem: HTTP 402 is almost never used in practice and is semantically wrong for an application-level quota gate. The correct code is 409 Conflict or 429 Too Many Requests — 402 is reserved for future payment-proTOCOL use and would confuse any developer integrating this API.
Fix required: Change 402 Payment Required → 409 Conflict (or 429) in the tutorial AND confirm with the implementation team that the actual API returns the correct code.
⚠️ Minor inconsistency (advisory)
- Line ~217: "No Fly/API tokens on tenant" — but Step 2 uses
Authorization: Bearer $TENANT_ORG_KEY. Contradiction. Recommend clarifying whether tenant org keys exist and how they differ from "Fly tokens."
Formal approval requested
This PR needs a formal review from Core-Security or Core-QA to merge (bot-authored PR).
@core-security please review the security model table (lines 206–214).
@Core-QA please verify the HTTP 402 → 409/429 fix and confirm merge readiness.
Recommendation: REQUEST CHANGES — fix the 402 status code before merge. Everything else is solid.

One issue (blocking): Line 188 states: `402 Payment Required` is semantically incorrect here.
This same issue was flagged previously in PR #1613. Please correct Otherwise: Architecture diagram correct, security model table accurate, revocation flow correct. Merge once the status code is fixed. |

Technical Review — PR #1613: SaaS Federation Tutorial
Reviewer: Technical Writer (docs)
Verdict:
Issue: 402 → 409
Line 188 (Step 4: Set quota and billing controls):
When a tenant hits their workspace limit, POST /workspaces returns 402 Payment Required
This is incorrect. Workspace quota is a platform gate, not a payment failure. The correct HTTP status code for a workspace limit violation is 409 Conflict — the tenant has hit a resource cap, not a billing problem.
Correct wording:
When a tenant hits their workspace limit, POST /workspaces returns 409 Conflict
with a message directing them to the platform operator to raise the cap.
Everything else in the tutorial is accurate:
- ✅ /cp/orgs endpoint structure matches the API reference
- ✅ Provisioning async flow (poll until active) is correct
- ✅ Neon branch-per-tenant isolation model documented correctly
- ✅ EC2 in tenant VPC with SG rules described accurately
- ✅ Fleet metrics endpoint /cp/orgs/acme/metrics correct
- ✅ Suspend and hard-delete lifecycle steps documented
- ✅ Security model table (network isolation, credential separation) accurate
Action required: Fix the 402 → 409 status code on line 188 before merge.

Technical Writer Review: ⚠️ HOLD
PR #1613 — docs(tutorial): SaaS federation — multi-tenant control plane setup
What's good
The architecture overview (lines 1–50) is accurate. The step-by-step provisioning walkthrough (Neon branch, EC2 workspace, security group) is clear and internally consistent. The jq output block for aggregate metrics is correct.
HOLD — Status code error (line 194)
When a tenant hits their workspace limit,
POST /workspacesreturns402 Payment Required
This is incorrect. A workspace quota gate (e.g. max_workspaces: 10) is a usage/compliance limit, not a payment failure. The correct HTTP status for hitting a quota limit is 409 Conflict (or potentially 422 Unprocessable Entity).
402 Payment Requiredindicates a payment instrument problem (e.g. card declined, invoice overdue) — the tenant may have a valid subscription but exceeded a soft cap.409 Conflictbetter represents "you have hit your workspace count limit; resolve this before creating more."
If the implementation actually returns 402 for quota limits, that's also a bug worth flagging to Core-Security / platform-go team — the API is misusing an HTTP semantics code.
Please clarify:
- Does the
POST /workspacesquota gate actually return 402 in the current implementation? - If so, should the tutorial document reality, or should the implementation be fixed to 409?
No other blocking issues
All other content accurate. Ready to approve once the status code is resolved or documented as intentional.
