CRK — Civilization Reboot Kit

Bundle your local snapshots, hash them with SHA-256, and verify an incoming bundle byte-for-byte. Everything below runs in your browser — no server, no upload. Syncing to another node requires an offline transfer (USB stick, QR, satellite, mesh) that this page doesn't automate.

Verification spec

SHA-256 WebCrypto SubtleCrypto.digest("SHA-256", bytes)
JSON Deterministic stringify: object keys sorted recursively.
Signature Out of scope for static site; HTML hash carries the receipt.

Storage keys

Each CRK thread owns its own localStorage namespace. Other pages do not overwrite these.

tasks: serviceofothers_sln_tasks
ledger: serviceofothers_sln_crk_ledger
queue: serviceofothers_sln_crk_queue

Bundle export & import

Export reads serviceofothers_sln_tasks, computes SHA-256, and downloads a JSON file with the hash embedded. Import verifies the hash before letting you apply the contents.

Import:

Last imported bundle preview

Cryptographic ledger

simulated

Capped at the last 50 entries. Every export appends the bundle header; every import appends a verification record.

Sync queue

hybrid

Local placeholder for offline sync. Status flips queued → synced once you press "Mark all synced".
