Two root-cause fixes for the sandbox failure where an inline Dockerfile came back from the store as `ARG REDACTED` and the Daytona snapshot build died on the unset variable. Entropy redaction measures values, not assignment pairs. The detector matched `NAME=value` as one token, so an uppercase name merged its charset into a pure-hex value (which alone can never exceed 4.0 bits) and pushed the pair over the 4.5-bit threshold — then replaced the whole pair, destroying the name. `find_entropy_regions` now strips an identifier-shaped `NAME=` prefix before measuring and redacts only the value, matching the gitleaks layer's `key=REDACTED` shape. Execution no longer reads redacted content. Every stored event passes through the redaction sink, and `load_from_store` rehydrated the worker's RunSpec from the projection folded from those events — so a redactor false positive silently rewrote the spec the sandbox builds from (and changed its snapshot identity). The creation path now writes the exact spec bytes to the content-addressed blob store and records `spec_blob` on run.created; `load_from_store` loads the spec from the blob, keeping the event stream authoritative for run identity, provenance, and event-recorded blob ids. Retry and fork carry the source run's `spec_blob` forward, so derived runs stop inheriting the redacted copy. Runs created before the blob existed fall back to the folded spec. The projection and every API surface keep serving the redacted fold; blobs were already stored unredacted (the workflow bundle carries the same bytes), so this adds no new exposure at rest.
