Robert Allan JamesandClaude Sonnet 5 8a2ee0fdad Payload bound and chunking -- FABRIC-3.6.md task 3.5
sk_hermes_publish() now enforces SK_HERMES_CHUNK_MAX_PAYLOAD (1024) on
every message's payload_len uniformly, chunked or not -- closing the
gap task 3.3 explicitly parked. A chunk carrier is
[SkHermesChunkHeader][content slice], slice capped at
1024 - sizeof(header) rather than 1024 itself, so every message on the
wire satisfies the same one-block bound vm_interpret()'s own drain
limit already requires -- a future chunk-aware drain never has to
special-case a carrier that can't be handed to vm_interpret() as-is.

Deliberately no chunking-sender API: building one would need
kernel-Hermes to own chunk-buffer memory with a real lifetime it has no
way to track (kept alive until every subscriber drains it). Sending is
a loop pattern a caller writes with sk_hermes_chunk_count() +
sk_hermes_publish(), demonstrated by this task's own self-test.
sk_hermes_reassemble() is pure and memory-agnostic: validates msg_id
agreement, exact seq coverage, and per-chunk slice sizes before a
single memcpy, with the total length computed once and checked against
the caller's buffer once -- never order-dependent on which chunk
happens to overflow.

Verified live on all three architectures: a 1024-byte payload as one
message, a 1025-byte send refused outright with the ledger untouched,
and a 3000-byte payload split into 3 chunks, drained, and reassembled
byte-exact against the original. dict_hash unmoved and identical
across architectures.

logs/

QEMU acceptance-run history and Tripod smoke-test results.

  • <timestamp>/{amd64,aarch64,riscv64}/ — 255 timestamped three-arch QEMU acceptance run directories, one per invocation of the kernel QEMU acceptance workflow.
  • qemu-screenshot-*.png, qemu-screenshot-*.log, qemu-{amd64,aarch64,riscv64}-*.log, fbtest-console-*.png — loose timestamped QEMU serial captures and framebuffer screenshots from individual manual runs (not part of the timestamped-directory convention above).
  • hermes-tripod-smoke-results.md, hermes-channel-smoke-results.md — captured output from tools/hermes_tripod_smoke.sh and tools/hermes_channel_smoke.sh.
  • hermes-tripod-integration-design.md — design notes for the Tripod integration test.

Note: QEMU_BASELINE.log at the repo root (not in this directory) is the primary kernel regression baseline referenced by .claude/CLAUDE.md; the logs here are supplementary historical captures. See also logs2/ (a separate, flatter QEMU log archive) and experiments/bare_metal/runs/ (DoE-specific run output).
