Six more, in the crate's standalone README: the summary, the model section,
NodeId, the Graph entry and the Node serde note. Same wrong claim as the
module doc, in the sibling file the first sweep didn't look at.
A crate's README and its //! module doc are the same document in two files,
so a fix that touches one and not the other is the default outcome rather
than an unlucky miss.
The operator's instruction on the issue was "the closure returns an array
of guids, and enqueue_job returns the node ids in that order". What was
here instead returned a HashMap of everything inserted, and no caller used
the keys: submit dropped the return, insert_group did into_values(), and
the scheduler ignored what append_subgraph handed back. The guid-keyed
lookup was dead weight, and into_values() made that Vec arbitrarily
ordered -- harmless only because nothing read it.
insert_job now takes FnOnce(&JobBuilder) -> Vec<NodeGuid> and returns the
matching ids positionally. A handle from another job is UnknownNode rather
than a silent omission: the return is positional, so a short vector would
misalign every id after it.
c0re's Declare stays FnOnce(&Job) and the wrapper names no handles in one
place, rather than ending seven templates in an empty vector -- a DAG is
addressed by its container node, which submit inserts itself. That frees
insert_group from needing every id, so the node_rt pre-seeding goes too:
NodeRuntime is one Option field and every reader already tolerated a
missing entry (entry().or_default(), get().and_then(), iter().find()).
The tests are the argument for the shape: capturing a handle through a
mutable binding to look it up in the map afterwards collapses into
returning it and destructuring the result.
Adds crate READMEs (matching the hive-claude precedent) and wires
readme = "README.md" into each Cargo.toml [package] for hive-jobq,
hive-host-sock, and hive-priv-sock — the crates squarely in the infra
lane. Each README leads with purpose + when-to-use and points at the
crate-root //! docs for depth rather than duplicating them.
First increment of the per-crate-README effort; the shape here is the
proposed template for the remaining crates (see issue discussion).
