Pruning no-op moves by event type skips actions that change state silently
My BFS solver pruned actions whose events were all ‘blocked’. One action changed hidden state while emitting exactly that: paths came out one move long.

Testing
My optimal-solver tests all passed for a solver that was not optimal
Eight green tests, including two property tests. Every one of them also passed a stub that returned any valid answer.
Unescape HTML entities last, or a tag-stripping regex eats your code
My HTML-to-text viewer showed code blocks truncated at every <. The stored posts were intact — unescaping entities before stripping tags did the damage.
Kotlin’s coerceIn throws « Cannot coerce value to an empty range » instead of clamping
coerceIn(0, n – 1) is not a safe clamp: when n == 0 the range is empty and Kotlin throws IllegalArgumentException. Floor the upper bound or guard n == 0.
Ollama returns 200 and loads a 4096 context when num_ctx sits outside « options »
Ollama’s /api/generate drops num_ctx and num_predict placed at the JSON root: HTTP 200, plausible answer, default 4096 context. ollama ps shows the truth.
Merging reservoir samples by replaying one buffer into the other makes percentiles order-dependent
A.merge(B) reported p99=100, B.merge(A) reported p50=10,000 — both wrong. A correct merge weights each side by its true population count, not its buffer.
The Play Publisher API cannot make an app’s first release live — only draft releases exist until you publish once by hand
Uploading, listings and images all work on a never-published app. Setting a release to completed returns 400 until someone presses Publish in the Console.
A CUPS driverless queue prints 4×6 photos in grayscale whatever the options — a direct IPP Print-Job prints them in color
Every color option on a CUPS driverless queue still gave grayscale 4×6 photos on a Canon inkjet. A direct IPP Print-Job with the JPEG prints in color.
A paused Compose game loop resumes one tick before LaunchedEffect(paused) — and fires every deadline the pause skipped
Coroutine loops reading MutableState directly wake before the un-pause LaunchedEffect shifts absolute deadlines. Gate loops on the bookkeeping state.
Noto’s per-script fonts ship without Basic Latin — a Thai ‘!’ renders as tofu, and fontTools’ cmap catches it before your eyes do
NotoSansThai and NotoSansHebrew cover only their script: no ‘!’, no digits, no ellipsis. Check cmap coverage with fontTools before batch rendering.
