read_only was the whole decision on the Hexis act path, which flattened three
answers into two. A capability that wipes the thing it names got the same
single spoken "да" as one that restarts a service, and requires_confirmation —
which the Hexis contract calls server-derived and never settable by a caller —
was read by nobody. docs/ecosystem.md §17.3 says confirmation follows risk.
RiskOfCapability reads Hexis's risk, read_only and requires_confirmation and
returns one of the three tiers internal/tool already had. It takes plain values
rather than a Capability, so internal/tool keeps no dependency on the Hexis
client. RiskOf keeps deriving, because a shell row the owner ticked on /tools
has no upstream to ask.
Every disagreement between the three fields goes up, never down: safe and
mutating is a contradiction and takes the confirm, an unrecognised tier takes
the confirm, and requires_confirmation may only raise. Same default as an
unrecognised dispatch shape — argue your way down, never up.
The irreversible refusal was a Go literal in two places and is now one deck
entry, act_needs_authed_surface. It lost four words to the persona ceiling.
Two caller-side halves of the same review.
«экосистема недоступна» named nothing. Nexus, Praxis and Hexis fail
independently, and every one of the six call sites already knew which one it was
talking to — it writes that name into the trace on the line above. So eco_down
and eco_denied now take {name}, and he hears which service refused him.
The list entries are single-variant and placeholder-only, so an empty list has
no shorter wording to fall back on: attention_list would render as its own label
and a colon. Both Praxis readers checked the response length and neither checked
what survived formatting, so an item with no title counted toward a list it
could not appear in. They skip the untitled item and fall to the _none entry
when nothing is left.
The ecosystem tests asserted the substring "выполнена", which was a literal out
of the act file that review has now reworded. Seventeen sites go through actRan,
which asks the file.

Several assertions passed against code with the behaviour removed. The
independent-outage test shared no state to begin with, the capability
fixture used to prove read-only filtering was already mutating, and
route-level faults were simulated with a separate fake instead of the
shared one. The harness now takes per-route faults and a ticking clock,
so durations are measurable and one dead endpoint can be shown not to
mute a whole service. New cases cover a resolved reference with no
entity, a rejected credential, a malformed Praxis body, foreign items
in a scoped response, named truncation, traces staying out of facts,
and enrichment making progress while its oldest batch is backed off.
Found in review of #82.
Vikunja #268 (P0): handleHexisAct swallowed genuine Nexus resolve errors
and Hexis capability-discovery errors into "" or an empty capability list,
which fell through to the local system command executor — a dependency
outage silently looked identical to "not an ecosystem entity" or "no
capabilities registered", violating the spec's degrade-independently /
never-silent-all-clear invariant.
- resolveEntityReference's error is now distinguished from a legitimate
not_found: only the latter falls through.
- discoverCapabilities now returns (caps, err) instead of collapsing a
Hexis failure into an empty slice; a real error stops the action with
a degraded-mode spoken reply instead of reaching h.tools.Exec.
- nexusResolveResult gains a custom UnmarshalJSON to accept the flat
entity_id/entity_type/display_name shape from ECOSYSTEM-SPEC.md §1.5
(Nexus now emits both shapes; Maven now reads both).
- Added regression tests: flat-shape resolve, Nexus error fails closed,
Hexis error fails closed, not_found still falls through to local exec.
Bring the Nexus/Praxis/Hexis integration in line with
MAVEN_ECOSYSTEM_ARCHITECTURE.md:
- Praxis over HTTP: drop the in-process praxis.db open (praxisstore/
praxistools) and call praxisd's /api/v1/tools/* API via a new praxisClient.
Honors the "no component reads another's DB" invariant (AC#12).
PraxisConfig.DBPath -> URL.
- Hexis confirmation gate: mutating capabilities (ReadOnly=false) now park a
bound pendingHexis confirmation and require a spoken "да" before executing;
read-only run immediately (AC#7, no auto attention->action).
- Capability safety: >1 verb match is ambiguous -> ask instead of firing the
first; ambiguous Nexus resolution asks for clarification (AC#2).
- Correlation IDs on Hexis execute, recorded in the cross-service trace.
- Bug: importance arrives as JSON float64 over HTTP, not int.
- Tests: confirm-gate, decline, read-only, and ambiguity paths.
Build: vendor/ bakes in the hexis client (replace-directed at a sibling repo
outside the Docker context); Dockerfile builds from vendor and no longer
`go mod download`s the unreachable replace paths.
