3. **Verify a peer exactly as you verify yourself.** Peer status buys nothing: check the claim

against the code, and re-run the build. A peer's correction gets the same treatment — right or

wrong on the evidence, not on who said it. Neither of you merges the other's work unreviewed.

**N observations are N data points only if they differ in the axis you are trusting.** This cuts

4. **Ask a peer to read your project addendum.** Your addendum is instruction surface: every future

/**
|

* fleetd #394 follow-up: the blanking loop's {@code eval "export ${n}="} splices {@code n} into
|
||||
* a string that zsh then interprets as shell syntax. That is only safe because every name
|
||||
* reaching {@code _cb633_blank} already passed an identifier check in the ENUMERATION loop
|
||||
* (20 lines away, in a different loop) — so the fix re-asserts the identical check immediately
|
||||
* before the {@code eval} call, rather than trusting that distant guard to keep holding.
|
||||
*
|
||||
* <p>This test plants a value with an embedded newline, exploiting the exact "junk from
|
||||
* multi-line values" gap the enumeration loop's own comment already documents: {@code command
|
||||
* env}'s text output is read line-by-line, so a value's second line becomes a spurious extra
|
||||
* "name" that was never a real exported variable. The fragment used here ({@code
|
||||
* junk.fragment}) is merely non-conforming (it contains a dot) — never command-shaped; this
|
||||
* test must never demonstrate command execution and plants no command-shaped payload.
|
||||
*
|
||||
* <p>Exercises the real artefact end-to-end: {@link EnvAllowListScrub#scrubScript} runs
|
||||
* verbatim under a real {@code /bin/zsh}, exactly as {@code generate()} would produce it — this
|
||||
* is not a synthetic call into just the blanking loop.
