Repair SvelteKit Form Action CSRF Origin Rejection
Example session with this skill installed
Case: A web form stops saving changes after reverse proxy deployment.
Provided: SvelteKit action requests and reverse proxy origin forwarding headers (illustrative, partial). Potential exception: origin mismatch check rejects a legitimate proxied POST request. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

Repair SvelteKit Form Action CSRF Origin Rejection — SYNTHETIC EVIDENCE-LIMITED REVIEW
Case received
A web form stops saving changes after reverse proxy deployment.
Evidence register
- S1: SvelteKit action requests and reverse proxy origin forwarding headers — PARTIAL / UNVERIFIED.
- S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
- S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
- S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.
Investigation checks
- Establish the identity, timestamp basis and revision lineage of SvelteKit action requests and reverse proxy origin forwarding headers; document missing or contradictory records. — PENDING CORROBORATION.
- Reconstruct the event sequence surrounding origin mismatch check rejects a legitimate proxied POST request, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
- Compare the evidence with the approved baseline; test the competing explanations for: A web form stops saving changes after reverse proxy deployment. — PENDING CORROBORATION.
- Draft a non-executing, owner-approved validation sequence and rejection criteria for form security origin regression fixture. — PENDING CORROBORATION.
Deliverables
- time-aligned evidence index for SvelteKit action requests and reverse proxy origin forwarding headers: DRAFT / INCOMPLETE until inputs are validated.
- exceptions and alternative hypotheses for origin mismatch check rejects a legitimate proxied POST request: DRAFT / INCOMPLETE until inputs are validated.
- approval-gated form security origin regression fixture and verification criteria: DRAFT / INCOMPLETE until inputs are validated.
Decision gate
INCOMPLETE — HUMAN REVIEW REQUIRED. Sources, scope, time basis and sign-off remain unverified. No live change or approval has occurred.
