From da418575620efd3598a88f5777f59e4d29dcea40 Mon Sep 17 00:00:00 2001 From: Pal Lakatos-Toth Date: Sun, 28 Jun 2026 07:08:02 +0200 Subject: [PATCH 01/17] feat(team): KarsTeam standing-team primitive with charter cadence loop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the durability-axis primitive (design note §11): a KarsTeam CRD plus reconciler that materializes a principal KarsTask (full envelope) and member KarsTasks (attenuated, parented to the principal), then runs a charter cadence loop that mints and launches task-force KarsTasks on schedule — the autonomous monitoring mechanism for standing operations (monitoring a repo/org, periodic checks). The reconciler authors KarsTasks rather than re-implementing sandbox materialization, so all existing attenuation enforcement, mesh agent loop, receipts, and metering are reused unchanged. Fully additive: a cluster with no KarsTeam objects behaves identically. - controller/src/kars_team.rs: KarsTeam CRD (charter, envelope, roster, cadence, blueprint, reporting_to, knowledge_commons, paused), validation + commons_name - controller/src/kars_team_reconciler.rs: principal/member materialization + charter cadence loop (PHASE_ACTIVE/DEGRADED/HIBERNATING) - crd_validations.rs: kars_team_crd() + CEL (tier range, ceiling<=tier, charter) - helm crd-karsteam.yaml + helm_drift dump/match tests - phase.rs: PHASE_HIBERNATING; field_managers.rs: CLAW_TEAM; main.rs: wire reconciler Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- controller/src/crd_validations.rs | 54 ++ controller/src/field_managers.rs | 5 + controller/src/helm_drift.rs | 30 +- controller/src/kars_team.rs | 354 +++++++++++ controller/src/kars_team_reconciler.rs | 520 +++++++++++++++++ controller/src/main.rs | 9 + controller/src/status/phase.rs | 6 + deploy/helm/kars/templates/crd-karsteam.yaml | 584 +++++++++++++++++++ 8 files changed, 1560 insertions(+), 2 deletions(-) create mode 100644 controller/src/kars_team.rs create mode 100644 controller/src/kars_team_reconciler.rs create mode 100644 deploy/helm/kars/templates/crd-karsteam.yaml diff --git a/controller/src/crd_validations.rs b/controller/src/crd_validations.rs index 7a42de24b..9428726bf 100644 --- a/controller/src/crd_validations.rs +++ b/controller/src/crd_validations.rs @@ -57,6 +57,7 @@ use crate::kars_memory::KarsMemory; use crate::kars_receipt::KarsReceipt; use crate::kars_sre_action::KarsSREAction; use crate::kars_task::KarsTask; +use crate::kars_team::KarsTeam; use crate::mcp_server::McpServer; use crate::tool_policy::ToolPolicy; @@ -617,6 +618,59 @@ pub fn kars_task_crd() -> CustomResourceDefinition { .expect("kube-rs derive must produce a spec property on KarsTask") } +/// Admission CEL for `KarsTeam` — the standing-team envelope must obey the same +/// anti-amplification rules as a task (tier range, ceiling <= tier, depth >= 0), +/// plus a non-empty charter (the mandate that generates the team's work). +pub fn kars_team_validations() -> Vec { + vec![ + ValidationRule { + rule: "size(self.charter) > 0 && size(self.charter) <= 8192".into(), + message: Some("spec.charter must be 1-8192 characters".into()), + reason: Some("FieldValueInvalid".into()), + ..ValidationRule::default() + }, + ValidationRule { + rule: "self.envelope.tier >= 1 && self.envelope.tier <= 5".into(), + message: Some("spec.envelope.tier must be in 1..5".into()), + reason: Some("FieldValueInvalid".into()), + ..ValidationRule::default() + }, + ValidationRule { + rule: "self.envelope.authorityCeiling >= 1 && self.envelope.authorityCeiling <= 5".into(), + message: Some("spec.envelope.authorityCeiling must be in 1..5".into()), + reason: Some("FieldValueInvalid".into()), + ..ValidationRule::default() + }, + ValidationRule { + rule: "self.envelope.authorityCeiling <= self.envelope.tier".into(), + message: Some( + "spec.envelope.authorityCeiling must be <= spec.envelope.tier (a team cannot grant a member more authority than it holds)".into(), + ), + reason: Some("FieldValueInvalid".into()), + ..ValidationRule::default() + }, + ValidationRule { + rule: "self.envelope.delegationDepth >= 0 && self.envelope.delegationDepth <= 16".into(), + message: Some("spec.envelope.delegationDepth must be in 0..16".into()), + reason: Some("FieldValueInvalid".into()), + ..ValidationRule::default() + }, + ValidationRule { + rule: "!has(self.cadence) || !has(self.cadence.everyMinutes) || self.cadence.everyMinutes >= 1".into(), + message: Some("spec.cadence.everyMinutes, when set, must be >= 1".into()), + reason: Some("FieldValueInvalid".into()), + ..ValidationRule::default() + }, + ] +} + +/// `KarsTeam` CRD — the standing-team / org primitive (design note §11). +#[must_use] +pub fn kars_team_crd() -> CustomResourceDefinition { + inject_spec_validations(KarsTeam::crd(), kars_team_validations()) + .expect("kube-rs derive must produce a spec property on KarsTeam") +} + #[must_use] pub fn kars_receipt_validations() -> Vec { vec![ diff --git a/controller/src/field_managers.rs b/controller/src/field_managers.rs index 2f33aa20b..99419481d 100644 --- a/controller/src/field_managers.rs +++ b/controller/src/field_managers.rs @@ -57,6 +57,11 @@ pub const CLAW_EVAL: &str = "kars-controller/karseval"; /// envelope digest + lifecycle phase on status. pub const CLAW_TASK: &str = "kars-controller/karstask"; +/// `KarsTeam` reconciler — the standing-team primitive.

Append-only, provenance-tracked entries (id, author, source run, timestamp, content digest, size), budget-bounded with oldest-first pruning. ensure_commons / record_entry / prior_knowledge. Two load-bearing paths make this functional memory, not a display: - Write path (autonomous): when a standing-operation run completes with a substantive deliverable (tokens spent or artifacts produced — harness-neutral), the reconciler harvests its output into a commons entry, then retires the run's sandbox (launch=false) so runs never pile up. Backpressure caps concurrent runs so the charter loop can't outrun completion. - Read path (functional): when minting the next run, the most recent commons entries are injected as prior knowledge into the run objective, so the team builds on what it already knows instead of starting cold each tick. Runs are driven to completion autonomously via the existing mesh run-request annotation. Verified live: run (13646 tokens) -> harvested with provenance -> sandbox retired -> next run objective carries the prior-knowledge preamble.

Only after the warm-up budget is spent is a terminal 'agent never came online' result written. Tracked via the run-attempts annotation. - team retire: a run's sandbox is torn down only once delivery is terminal (deliverable landed AND run-completed stamped), so the team never pulls a sandbox out from under a run that's still warming up / retrying. Verified live: a fresh standing run delivered ok with 28291 tokens and no timeout, then retired cleanly.

A KarsTeam with spec.profileRef inherits the profile's charter (if empty) + roster (if empty) — domain-blind platform, domain in the profile. - Governed promote (§12): KarsTeam.spec.requestedTier opens a human tierRaise KarsApproval against the principal; only on approval does the controller widen the envelope (controller-only raise — enforced by the envelope-write VAP), and the approval is bound into the principal's receipt (human-approved + ledgered). - Capability-readiness gate (§19): the charter loop checks every referenced MCP server is provisioned + Ready before minting a run; if not, it pauses-with- reason (clear status detail) instead of dispatching a doomed run that loops.
