`age_seconds` is documented on the LooseEnd enum as saturating to zero on
any clock anomaly, but the derivation was in three places: hive-c0re had a
named `saturating_age` helper with tests, and the in-agent socket server
hand-rolled the same two lines twice, untested.
Move the helper to hive-sh4re::inbox, beside the enum whose contract it
implements and inside the one crate both producers already depend on. Its
three tests move with it (not dropped) and gain two arms: the whole-i64
range, where the saturating_sub is what stops the subtraction overflowing,
and a far-past control so those zeros are the clamp firing rather than the
function bottoming out on large inputs.
The two clamps are not redundant, which is what `to_loose_end`'s doc got
wrong: it credited "saturating" for the zero, but saturating_sub bottoms
out at i64::MIN, still negative. The try_from is what yields 0.
Also cover the two projections themselves, which is the part the shared
helper cannot: that a reminder ages from created_at rather than due_at,
and a todo from updated_at, with a future timestamp reading 0 through
both and a past-timestamp control on each.
Per mara's go-ahead on hyperhive#3902 ("getting started is good, but
terminal rendering does not go in there i think"):
Moved 21 top-level docs/*.md files into 7 new topic subdirectories
(existing web-ui/, turn-loop/, swarm/, tools/, crates/ untouched):
getting-started/ setup.md
agent-lifecycle/ agent-hierarchy.md, approvals.md, persistence.md
trust-boundary/ boundary.md, security.md
integrations/ forge.md, matrix.md, github.md, knowledge.md
networking/ gateway.md, network.md, snapshot-store.md
scheduler/ jobq.md, coordinator.md, ci.md, observability.md
process/ conventions.md, gotchas.md, pr-review-gate.md
web-ui/ terminal-rendering.md (moved into the EXISTING dir,
per mara's correction to the original getting-started
guess -- it's UI implementation detail, not onboarding)
The physical layout now matches docs/README.md's own topical headers,
which already amounted to this taxonomy -- see the scoping comment on
the issue for the two findings that motivated this (a genuine
duplication between CLAUDE.md's old "Reading paths" list and
docs/README.md's grouped one, since drifted out of sync with each
other; and the flat layout not matching the grouping we already had).
Fixed every cross-reference this moved across the whole repo (~120
files: docs/ internal links at every depth, Rust doc comments, nix
module option docs, crate READMEs) -- verified two ways: a grep sweep
confirming zero remaining references to any old path, and a script
that resolves every markdown link in docs/**/*.md + CLAUDE.md +
README.md against the filesystem and reports anything that doesn't
exist (zero broken links).
Collapsed CLAUDE.md's "Reading paths" section (the duplicate) down to
a pointer at docs/README.md, now the single index. Rewrote
docs/README.md itself to use the new subdirectory paths and added the
one doc it was missing that CLAUDE.md's old copy had (pr-review-gate.md).
Classified all 22 docs/*.md files first via a haiku subagent (mara's
suggestion) on two axes -- proposed grouping and operator-vs-
implementation focus -- before finalizing the taxonomy; spot-checked
the report and found internal inconsistencies (its classification
table disagreed with its own summary section for a few files), so this
taxonomy is my original proposal + the one correction mara gave
directly, not a blind application of the subagent's table. The
operator-focus data it gathered is still useful for a follow-up
content pass (docs skewing 'mixed' rather than pure operator-facing),
not addressed in this PR -- structure only.
nix fmt clean, both pre-push lints clean.
Closes the #3110 split — lib.rs is now just the crate doc comment and
the pub mod list.
journal.rs's new doc comment fixes a pre-existing bug: the old
JournalPriority doc text in lib.rs was actually half Capability's doc
(a leftover from an earlier reorder that moved the code but not the
comment above it).
