+# M13-04C Status
+
+status: done  
+task: server job resource budget gate  
+updated: 2026-08-19 America/New_York  
+enablingTask: false  
+parityStateChange: false
+
+## Scope
+
+Server jobs now have fixed CPU, memory, process, file, wall-time and output-byte limits. Budget
+parsing rejects undeclared fields and out-of-range values. A usage receipt is marked
+`enforced=true` only when every measured value is within its corresponding limit; each of the six
+over-limit cases returns `SERVER_JOB_BUDGET_EXCEEDED` and remains `execution=DISABLED`.
+
+This is the resource contract and usage gate. OS/container enforcement is proven by the later real
+process task and is not claimed here.
+
+## Evidence
+
+- `node --test web/tests/unit/server-job-resource-budget.test.mjs` passed 2/2.
+- `npm --prefix web run test:server-job-resource-budget` passed unit 2/2 and the independent checker.
+- `node tools/web/check-server-job-resource-budget.mjs` passed:
+  `server-job-budget-ok cpu=bounded memory=bounded process=bounded files=bounded wall=bounded output=bounded overages=6 execution=DISABLED next=M13-04D`.
+- `npm --prefix web run typecheck`, `npm --prefix web run lint` and `git diff --check` passed.

+## Next Task
+
+`M13-04D`: default-deny network policy with explicit declared-origin admission.
+
+## Rollback
+
+Remove the resource budget protocol, focused tests/checker, report, manifest, package command and
+this status entry; restore M13-04B as the queue tail and move `nextTask` back to `M13-04C`.
