feat: accept openBenches handoff environment - #341
Conversation
Reviewer's GuideMigrates handoff environment inputs to OPENBENCHES_CLAUDE_* with WORKBENCHES_CLAUDE_* fallback, rejecting conflicting dual values before side effects and documenting and testing the contract across both handoff implementations.

<issue_to_address>
**Environment values execute shell code**
When an `OPENBENCHES_CLAUDE_*` or `WORKBENCHES_CLAUDE_*` value contains shell syntax such as `$(...)`, `eval` reparses each environment value as shell syntax, so command substitutions or other shell commands embedded in a value execute during the check. The handoff therefore runs code supplied through the launcher environment.
Avoid `eval` for reading these variables; select among the fixed variable names with a `case` statement and expand the selected value directly.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 1 finding to address first, and a lone new environment value can supply the window or checkout recorded by a handoff; if that value is wrong, the handoff record can be wrong too. Reverting restores the old variable behavior but does not remove an already-written record, though that bounded record can be corrected or refreshed.

FindingsS1, SHOULD, for lane 3 to rule: the refusal fires even where the run never reads the variables.
S2, SHOULD, proven: the tests clear only the legacy names, so a host's
S3, SHOULD: surviving mutants show three gaps.
N1, NIT: Sourcery's blocking finding at
N2, NIT: the refusal message. N3, NIT: the precedence order is never observable. M1, which swaps the order, is an equivalent mutant, because every disagreement is refused before the reads. If S1 moves the refusal to the point of use, or to a skip, precedence needs its own test. CoverageNothing else in the repository reads or writes either prefix. A launcher that sets only
