Hosts set GENTLE_AI_CHANNEL in ad hoc conf.d files and disagreed (beta on agent-dev, nan, agent-refactoria; stable on agent-gentle, tars, Mac). gs sync installs from main, so 10-core.fish now defaults it to beta; 99-local.fish can override. Tested in w7 (default + override kept).

Post-merge QA (glm)

Defaults GENTLE_AI_CHANNEL to beta in 10-core.fish when unset or empty, overridable by 99-local.fish. The w7 test covers both the default and the override-kept case with a clean env. Guard logic is correct for both unset and empty-string values. No defects found.

No findings.

Verdict: clean

Post-merge QA (deepseek)

Lens: evidence + test design.

The change is small and well evidenced. 10-core.fish now sets GENTLE_AI_CHANNEL to beta only when the variable is unset or empty, so an explicit host value (including an empty-but-deliberate value edge handled by the -z test) still wins, and 99-local.fish.example documents the override in the file operators actually copy. w7-gentle-ai-path.fish exercises both halves against the real file with env -i: the default expands to beta and a pre-set stable survives sourcing. The fish condition (if not set -q GENTLE_AI_CHANNEL; or test -z "$GENTLE_AI_CHANNEL") is safe because a quoted expansion of an unset fish variable yields one empty argument, so test -z never sees the wrong arity.

No defects found. One note: the tests source 10-core.fish directly, so they prove the variable's value but not the downstream channel selection it is meant to influence.

Suggestion (1)

• Only the variable value is asserted, not the effect on gentle-ai (fish/tests/w7-gentle-ai-path.fish:27): The stated motivation is that hosts disagreed about which channel gentle-ai install/upgrade and engram downloads follow. The test proves GENTLE_AI_CHANNEL ends up beta (and that an override survives), which is the mechanism, but nothing asserts that a gentle-ai invocation under this environment actually receives the channel — e.g. a shim that echoes the variable it was launched with. That is acceptable for a dotfiles repo, but it should be stated as the boundary of the evidence.

Verdict: clean
