Competition Browser Persistence

Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.

Use this skill when the decisive branch lives in browser-held state rather than only in visible HTML or backend source.

Quick Start

  1. Identify the active persistence surface first: cookie jar, localStorage, sessionStorage, IndexedDB, Cache Storage, or service worker.
  2. Record origin, scope, domain, path, expiry, and key names before mutating state.
  3. Tie stored state to one concrete effect: request header, rendered branch, cached response, offline behavior, or hidden route access.
  4. Separate boot-time state from runtime-mutated state.
  5. Reproduce the smallest stateful sequence that reaches the decisive branch.

Workflow

1. Map Browser State Surfaces
