Retained state on the SSH stream path was unbounded in three places. Stream assembly and pre-metadata buffering - `ssh-stream-reader-memory.ts` adds two shared budgets: an aggregate assembly ceiling (128 MiB across all in-flight streams) and a pre-metadata frame budget (256 frames / 32 MiB). Every reader sees all stream frames and cannot filter by streamId until its own sentinel resolves, so a foreign flood previously grew unbounded while a reader waited. - The per-frame oversize check is load-bearing beyond memory: without it the eviction loop can never satisfy its exit condition on an empty buffer and spins forever. Covered by test. - Assembly is split into `ssh-file-stream-assembler.ts` and `ssh-git-response-stream-assembler.ts`, both reserving from the shared budget and releasing on every terminal path. - Git response stream markers are validated against client-side byte and chunk ceilings before allocation, so a relay-advertised size cannot force the allocation directly. Frame decoder - An oversized frame header is now answered by retaining only the 13-byte header and stream-discarding the advertised payload, so a malicious length field cannot pin up to 4 GiB waiting for bytes that never arrive. - Adversarially tiny transport fragments are coalesced pairwise, bounding the chunk-wrapper array without copying ordinary chunks. - Frame encode/decode route through the bounded stringify and parse helpers. Multiplexer dispose - Dispose handlers unsubscribe themselves while running, so iterating the live array skipped every other handler and stranded the assembly budget of half the in-flight streams. Detach before dispatch. WSL hook fs bridge - The bridge and its host adapter now pass and enforce the directory-entry and read-byte ceilings the shared contract already declared, so a listing of an arbitrarily large guest directory is refused at the source rather than serialized into a multi-megabyte frame. All new bounds are mutation-tested: reverting each one fails at least one test. Co-authored-by: Orca <help@stably.ai>
