Subject: [PATCH] test: red for show's no-project refusal blaming the id (#300
 fieldtest)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Outside any project, show_process/show_campaign print 'not found in the
project store' — asserting a store that does not exist and blaming the
id, where the sibling verbs (campaign_runs, validate) degrade honestly
naming the missing Aura.toml. The in-process RED pins: the refusal
stays Err, its prose names 'no Aura.toml found up from', and does NOT
claim 'not found in the project store'. Diagnosed cause: both show fns
lack the env.provenance().is_none() guard their siblings use, so the
no-project fallback store's Ok(None) masquerades as an unregistered id.
