ADR 0017 capped a module route at 1 MiB and said large media belonged to a future storage design. That design arrived — ADR 0030 gave modules a bucket, ADR 0031 took Ekklesia out of the read path — and it did not solve the write path: signed write URLs were deliberately declined, so the only way bytes reach a bucket is a module's own route, and a photograph is not 1 MiB. Extend the route contract rather than adding a second HTTP system. A route declares `bodyMode`: `buffered` (the default, and what every existing route already meant) keeps the 1 MiB ceiling and materializes the body before the handler runs; `streamed` raises the ceiling to 32 MiB and counts bytes as the handler consumes them, holding nothing. The mode is explicit rather than inferred from the size, because inferring it would mean an author who raised a limit silently changed how their own handler receives its body and when a 413 can reach their own code. 32 MiB holds one 25 MiB image plus bounded overhead and is also the platform's absolute ceiling: no route in any mode may declare more, and no unbounded option exists in the contract. The unit is one file per request — twenty images are twenty individually bounded requests, and nothing here can express a 500 MiB aggregate whose failure would waste everything already sent. Replace the buffering dependency with the platform's own limiter. A declared Content-Length over the limit is refused synchronously, before authorization and before a byte is read. Buffered mode now counts what actually arrives rather than trusting the header, which closes a gap the previous implementation had. Streamed mode wraps the body in a counting transform; on overflow the stream errors, the source is cancelled, and the response is replaced with the same sanitized 413 even if the handler swallowed the error — a limit a handler can swallow is not a limit. An unread body is cancelled so an abandoned upload releases its socket, and an abort stays an ordinary failed request rather than becoming a 413. Ordering is unchanged and now strictly better: in streamed mode no byte is read until the handler reads it, and the handler runs only after authorization succeeds, so an unauthorized caller cannot push an upload through at all. The live suite uploads a real 25 MiB body over a real socket end to end. Co-Authored-By: Claude Opus 5 <[email protected]>

# Architecture decision records
|
|
|
|
ADRs capture durable choices that affect more than one package or phase.
|
|
|
|
- Filenames use a four-digit sequence followed by a short kebab-case title.
|
|
- Status is `Proposed`, `Accepted`, `Superseded`, or `Rejected`.
|
|
- Accepted ADRs are immutable except for status and cross-reference corrections.
|
|
- A changed decision receives a new ADR that links to and supersedes the old one.
