A Chainsaw `script` op runs its shell under exec.CommandContext with stdout and stderr wired to in-process buffers. When the op timeout fires it SIGKILLs the shell process alone, not its descendants, and cmd.Wait() does not return until every process that inherited the pipe fds closes them. An mc that keeps retrying an S3 call after the shell is gone holds the pipe open, so the op runs to mc's own exhaustion instead of stopping at its ceiling. This is why the bucket suite's verify-every-bucket-takes-a-write step ran 606s under a 300s ceiling. verify-s3-access shares that shape, so wrap each S3 and apiserver read in its own `timeout`: a hung read dies at a known budget and the op timeout stays a backstop. The 30s kubectl cap matches the terminal `k` wrapper the redis suite carries. The two `mc cp` PUTs take 45s, the budget verify-every-bucket-takes-a-write already gives a write, because a working PUT can still wait while the master grows a volume for a freshly created bucket; 15s left too little headroom on that grow and could turn a slow-but-healthy write red on an unrelated PR. The 15s cap on the mc reads has no terminal precedent: the backup-access preflight caps `mc cp` at 15s too, but inside a retry loop where a 124 costs one attempt rather than the step, so it is not one. Land each secret's encoded value in a file before base64 -d so a timed-out kubectl read (exit 124) stops the step under set -e rather than masking as an empty-credential mc alias set further down. The readonly-upload deny probe branched on mc directly (if mc cp ...), which suspends set -e, so a timeout there (exit 124) was indistinguishable from the access-denied non-zero the probe expects: a hung deny path would exit 124, take the false branch, and reach a green cleanup, the exact window this change bounds. Capture the status instead: exit 0 is the readonly regression, 124 is a timed-out probe, both fail; any other non-zero is the expected denial. The suite's own catch read (the `kubectl get pods` in namespace cozy-objectstorage-controller) carried neither an op timeout nor an inner cap, so it inherits timeouts.exec (5m) and can hold the pipe the same way; give it a 30s inner cap and a 1m op timeout so the rule the rest of the file follows holds for it too. The .chainsaw.yaml notes still read the op ceiling as a reliable cut, the old SIGKILL as a de-facto cap and a smaller timeout as guaranteeing a kill; correct them, since the shell-only kill plus the pipe wait are why an inner cap on every read is required rather than optional.
