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

• Inspect cookies, storage buckets, service worker registrations, cache entries, and transient globals exposed during boot.
• Record which origin, host, route, or feature flag each state item actually applies to.
• Keep auth tokens, refresh material, CSRF state, cached responses, and feature toggles in separate evidence blocks.

2. Tie State To Runtime Behavior

• Show how stored state becomes request headers, role derivation, route visibility, cached API data, or offline fallback behavior.
• Compare clean-state and mutated-state runs with one variable changed at a time.
• Distinguish UI-only state from backend-accepted state.

3. Reduce To The Decisive Persistence Chain
