stephrobert/feint v0.4.1 on GitHub

feint clean collects the state directories nobody was collecting.
Measured on a development station after one day: fourteen directories under
XDG_RUNTIME_DIR for two live emulators, twelve of which described nothing at
all. stop clears the record and leaves the directory holding the log — right
on its own, since a crash is read after the fact or not at all — but nothing
ever swept them, so the state directory stopped being readable as an answer to
"what is running". A live emulator is never touched, whatever its age.
feint clean --vm off now exits 0. It swept, it said so, and it exited 1,
because the sweep used to be reachable only through a machine runtime. off
is the default of serve and the majority of runs, so this was the common
path rather than an edge — and a success that exits like a failure is the
ambiguity this project refuses everywhere else. A runtime that genuinely
cannot be swept still fails.
The message nothing was left behind gains on the runtime, and is now
printed in every mode. tools/conformance/scaleway/network.sh decides the
runtime is clean by matching that line, and it must not change its answer
because a directory was collected.

The roadmap carries the queue that came out of comparing this project with
LocalStack, paid tiers included, and the refusals that comparison forced.
Three items outrank a batch, on one filter — which of them lower the cost of
coverage: recording what a real client and a real cloud say to each other, the
emulator as an importable package, and fault injection. The refusal to
intercept DNS and terminate TLS is reopened as a question rather than
decided: the measurement it rests on stands, the cost estimate that followed
it was never made.
CONTRIBUTING.md says how an issue title reads. A defect is titled by the
symptom, because the diagnosis is often wrong when the issue is opened and the
title outlives it; a unit of delivery carries its batch code, which is what a
commit closes it by naming.
