Add `media.maxBytes` to the top-level media config block (Zod schema, types, labels, help text) so users can override the hardcoded 5 MB inbound media staging/store limit. - Add setMediaMaxBytes()/getMediaMaxBytes() to store.ts (follows existing setMediaStoreNetworkDepsForTest pattern for module-level state) - Wire config read in gateway boot (server.impl.ts), always resetting to default when config omits the field - Update server.ts and stage-sandbox-media.ts to use the getter - Add formatBytesAsMb() helper for accurate error messages (toFixed(2)) - Schema caps the value at 500 MB; default remains 5 MB when unset Closes openclaw#40880

Enforce global media cap when per-channel maxBytes is passed
saveMediaBuffer now defaults maxBytes to the configured global limit, but the check still uses only the caller-provided argument, so any channel path that passes its own limit can bypass media.maxBytes. For example, inbound paths in src/web/inbound/monitor.ts and src/telegram/bot/delivery.resolve-media.ts pass channel-specific values, which means setting media.maxBytes lower (e.g. 10MB) does not prevent larger files from being persisted in the media store despite the new config being documented as the maximum accepted inbound size for store/staging.

Import getMediaMaxBytes in sandbox media staging
stageSandboxMedia now calls getMediaMaxBytes() when copying attachments, but this module never imports that symbol from src/media/store.ts. In runtime, each call throws a ReferenceError inside the try, then the catch logs and continues, so valid inbound files are silently skipped instead of being staged into the sandbox.

Import getMediaMaxBytes in media download route
The /media/:id handler uses getMediaMaxBytes() without importing it. When this line executes, it throws ReferenceError, which falls into the generic error path and returns 404, so valid media IDs can no longer be served by this route.

Wire media.maxBytes into startup limit initialization
This commit adds setMediaMaxBytes and a new media.maxBytes config field, but no startup path actually calls the setter (repo search for setMediaMaxBytes( at this commit only finds this declaration). As a result, the effective limit stays at the default 5 MB and the new configuration knob has no effect.

Thanks for the context here. I swept through the related work, and this is now duplicate or superseded. Close this PR as superseded by the open canonical issue: the requested configurability remains valid, but this stale conflicting branch has correctness blockers, no real behavior proof, and no longer matches current main closely enough to keep as the landing path. Canonical path: Keep #40880 as the canonical tracker and replace this stale branch with a current-main PR that defines the config contract, wires store/staging/chat preflight consistently, and includes real gateway proof. So I’m closing this here and keeping the remaining discussion on #40880. Review detailsBest possible solution: Keep #40880 as the canonical tracker and replace this stale branch with a current-main PR that defines the config contract, wires store/staging/chat preflight consistently, and includes real gateway proof. Do we have a high-confidence way to reproduce the issue? Yes, by source inspection and existing coverage: current main still has fixed 5 MiB store, sandbox staging, and chat preflight caps, and the gateway test constructs a 6 MiB PDF that is rejected as over the sandbox staging limit. I did not run a live gateway transfer because this review is read-only. Is this the best way to solve the issue? No, this branch is not the best current solution because it is stale, conflicting, has runtime import bugs, and does not initialize or thread the configured cap through the current Security review: Security review needs attention: No dependency or workflow supply-chain concern was found, but the media resource-limit boundary is inconsistently defined and not applied by the PR head.
