Codex convergence findings on the delegate-and-fold fix (code path verified
correct, prose only):
- The hook-bridges RFC claimed a downstream `block` "carries the bridge context
too" for BOTH seams. True for `tools/post-execute` (PostToolDecision.block has
an additionalContext field) but false for `agent/prompt-submit`
(PromptDecision.block is `{kind,reason}` with no context field). The code is
already correct — a blocked prompt drops the context, which is right since the
prompt never reaches the model. Reworded the RFC to state the per-seam
difference accurately.
- Two test comments narrated "Before the fix…", which the current-state-only
doc rule forbids. Reworded to describe the behavior, not its history.
- Documented on concatContext (both bridges) why the merged block carries a
single source: a HookContext holds one MessageSource and the seam cannot
represent mixed provenance; rendering distinguishes only by source.kind, so a
downstream plugin's text stays framed as plugin context.
