Commits on Oct 19, 2026
- fix(code-execution): a call's entry frees both functions if it can't be made; tests for the pieces none reached
  
  Gladys-2592
  and
  claude
  committed
  437312b
- fix(engine): vendor.sh replaces the copy only once it's whole; CI checks the copy against the pin
  
  Gladys-2592
  and
  claude
  committed
  8f9f427
- fix(code-execution): an ending is serialized once; a thrown object with no message is told by its JSON; the engine's own stdio is kept to its bound
  
  Gladys-2592
  and
  claude
  committed
  bcd3041
- fix(code-execution): the engine holds results to a depth, ends a run on a slot's failure however it shows, and keeps the script's code from the host once its ending is fixed
  
  Gladys-2592
  and
  claude
  committed
  7f04c8f
- fix(engine): vendor.sh applies patches and refuses over files it would erase; build.sh takes relative paths
  
  Gladys-2592
  and
  claude
  committed
  ae0628f
- fix(code-execution): an ending is read once even when reading fails, a stop while it's read is a stop, and the jobs a read queues can't reach the host
  
  Gladys-2592
  and
  claude
  committed
  dec7786
- fix(engine): vendor.sh refuses patches it would skip or drop, orders them by byte, and says how to recover a failed rename
  
  Gladys-2592
  and
  claude
  committed
  53c7413
- fix(code-execution): an ending past the engine's limit names the limit, and the allocator's comment says when its headroom can be spent
  
  Gladys-2592
  and
  claude
  committed
  68e02b0
- fix(code-execution): QuickJS's stack limit is 192 KiB at most, so deep recursion gets its catchable RangeError before the host's stack runs out
  
  Gladys-2592
  and
  claude
  committed
  50b55da
- fix(code-execution): a result's copy is freed once parsed, a stop after a whole ending leaves that ending, and dispose frees a runtime a slot's failure left whole
  
  Gladys-2592
  and
  claude
  committed
  f66b1e0
- fix(engine): vendor.sh sees every entry in engine/patches, checks each changed path whole, and puts the committed copy back if the new one can't go in
  
  Gladys-2592
  and
  claude
  committed
  115714e
- fix(code-execution): an exception that escapes the script's promises ends the run as failed, and a settle says when its result was dropped
  
  Gladys-2592
  and
  claude
  committed
  5c691cb
- fix(engine): vendor.sh refuses a listed file the patches change in kind, a link among the patches and an engine/patches that isn't a directory, and puts the committed copy back if stopped
  
  Gladys-2592
  and
  claude
  committed
  c492521
- fix(code-execution): a settle whose resolve call was stopped on its way in is dropped, and a failure stays the run's answer, after its ending and through a stop
  
  Gladys-2592
  and
  claude
  committed
  1e3e806
- fix(engine): vendor.sh cleans up whenever it exits, puts the copy back or says how, and names what it refuses
  
  Gladys-2592
  and
  claude
  committed
  efc9c49
- fix(code-execution): a stop stays a stop, a throw as the run starts is the script's own ending, and what a stop cuts off a failure's read is left out
  
  Gladys-2592
  and
  claude
  committed
  297b8e7
- fix(engine): vendor.sh's restore command puts back what's committed, its cleanup reports what it can't remove, and its comment says which signals run it
  
  Gladys-2592
  and
  claude
  committed
  bd62c6f
- fix(code-execution): once a stop has come, a failure with no message gets no stand-in for one, its string form included
  
  Gladys-2592
  and
  claude
  committed
  6f9c7bf
- fix(engine): vendor.sh's restore drops what the commit doesn't hold, it refuses over leftovers of a run killed outright, and its cleanup holds against a second signal
  
  Gladys-2592
  and
  claude
  committed
  0fd437a
- fix(code-execution): a stop ends a failure's read, and nothing after it is read
  
  Gladys-2592
  and
  claude
  committed
  6062d65
- fix(engine): vendor.sh's leftover refusal says what the entries are and to restore before removing them, and each notice about the committed copy is given once
  
  Gladys-2592
  and
  claude
  committed
  34f6bed
- fix(code-execution): the script's code QuickJS runs after a stop can't reach the host, and each part of a failure is a string before the next is read
