`topology.json` was a map of `name -> parent | null`, and that value fed
the whole agent hierarchy: `<parent>` / `<children>` recipient sentinels,
the reparenting API (CLI verb, wire verb, dashboard endpoints, DAG node),
the dashboard tree, the rebuild depth sort, and an unconditional
bind-mount grant giving every agent RW on its direct children's state.
Per the operator's ruling the field goes, and with it all of the above.
The file survives as what remains once the value is gone: the roster of
agent names, which is the set `ManageRootAgent` grants mounts over. It is
now a JSON array; `read` still accepts the old map shape and keeps its
keys, so a hive that upgrades across this does not blank its roster (and
so no capability holder loses its mounts for the length of that window).
Two sites kept their behaviour under a different recipient rather than
losing it. Both addressed `<parent>`, which the broker already resolved to
`operator` for a root agent, and every agent is now what that fallback
called a root:
- the harness's turn-failure / plugin-failure notification
(`Surface::send_to_parent` -> `send_to_operator`), and
- the send allow-list's always-permitted escape hatch, so an agent with a
restrictive allow-list still has a way to say it is stuck.
What is NOT preserved, deliberately: an agent with no capability no longer
sees any other agent's dirs. `ManageRootAgent`'s own grant is unchanged --
still every agent in the roster, still state RW + config RO, still no
`harness`.
The dashboard's reparenting control (the M0V3 picker) is deleted with its
CSS. The tree rendering that reads `ContainerView.parent` is left for the
frontend owner -- it degrades to a flat list with the field gone.
Both agent-facing tools go away end to end, with no replacement. This is
an intentional capability removal: agents can no longer enumerate their
own subtree, and can no longer queue a meta-flake input bump.
The system prompt and docs/tools/lifecycle.md land in this same commit
on purpose. A tool named in the prompt but absent from the server makes
agents confidently call something that doesn't exist, and the failure
then surfaces far from its cause.
Removed:
- MCP registrations and bodies (hive-agent-mcp), plus the now-unused
UpdateMetaInputsArgs.
- Wire variants Request::ListDescendants,
Request::RequestUpdateMetaInputs and Response::Containers, plus
ContainerInfo, whose only consumer was that response.
- hive-c0re's handle_list_descendants (its whole module) and
handle_request_update_meta_inputs, the two dispatch arms, and the
require_group(agent, "approvals", ...) gate on the meta-inputs verb.
- The stream_enrich emoji entry and argument formatter.
- docs/tools/lifecycle.md (both tools it documented are gone), its two
referrers, the tool-group tables and the agent-hierarchy prose.
Tool groups are kept, deliberately. ToolGroup::Lifecycle listed exactly
one tool and now lists none — it is vestigial, but the variant stays so
existing meta/capabilities.json grants still parse; retiring it is a
separate decision. ToolGroup::Approvals also listed exactly one tool,
but the group is NOT dead: check_can_cancel_approval still gates
cancel_loose_end's approval-cancel arm on it server-side.
ApprovalKind::UpdateMetaInputs stays too. Nothing in production code
produces it any more, but pre-existing approval rows may still carry it,
and the operator's own path to a meta update is unaffected — the
dashboard's POST /api/meta-update inserts the meta_update job directly,
bypassing approvals entirely.
The two format_ack tests in hive-agent-mcp that named
request_update_meta_inputs were only using it as a label string while
exercising the generic OkWarn/Ok renderer, so they are retargeted to a
surviving tool rather than deleted.
Note hive-c0re's priv_client::list_containers is a different thing (the
host-side privileged container listing behind hive-priv) and is
untouched.
Closes#4591
is_running collapsed every non-active state into false, so a container that
exhausted its bounded restarts read as plain "down" -- indistinguishable
from one an operator stopped deliberately. Bounding the restarts made that
gap sharper: a slow-failing agent used to grind on visibly, now it can stop
quietly.
Adds UnitState + unit_state() beside is_running rather than widening it.
is_running has ~8 call sites and nearly all are reconcile/power logic asking
"is it up? if not, start it" -- a question with two answers. Only the view
builder needs more, and it gets both facts from one systemctl call, since
is-active prints the state when not passed --quiet.
Surfaces as a flat failed flag on ContainerView and AgentStatusRow, matching
the shape those types already document: independent, orthogonally-observed
facts rather than a state machine. serde(default) keeps it order-independent
with the frontend half.
No behaviour change: nothing acts on the flag, per the ruling.
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).
