The team does not ship a test suite. It ships a product into a
particular environment for particular people.
That is why release readiness cannot be reduced to the percentage of
green checks.
/carbon-release turns the available technical and
product evidence into a scoped recommendation: ship, canary, hold, roll
back, or gather more evidence.
Match the
recommendation to the consequence
A feature available to ten internal users with an easy off switch has
a different release boundary from an automated action affecting every
customer. The same observed failure can lead to different
recommendations depending on exposure, reversibility, and
mitigations.
CARBON should consider severe failures separately from averages,
inspect the relevance of the evidence, and examine monitoring and
rollback readiness. A canary is not a magic compromise if nobody can
detect the failure or contain its effects.
Name the proposed release
/carbon-release assess a limited internal canary for the new assistant; use current evidence and identify monitoring, rollback, and unresolved blockers
The report should explain the recommendation, its scope, what remains
uncertain, and what observation would change the decision. A missing
critical check is not made irrelevant by twenty easy passes
elsewhere.
The command does not deploy the product or accept risk for the
organization. Release authority stays with the people responsible for
the consequences.
The useful outcome is a decision you can discuss and challenge with
evidence in front of you. Not a green badge that quietly asks everyone
to stop thinking.
