Completes the run-critic seam so a host adapter (mort's agentcritic) has full
fidelity, closing the two limitations gadfly surfaced on mort #1334.
- RecordStep(iter int, resp *llm.Response): the completed step's model response
is now passed to the critic (was index-only), so a host that records a trace
(mort's ProgressRecorder) can show what the agent actually produced, not just
an iteration count. The executor forwards s.Response; the battery ignores it
(its Progress is count-based).
- CriticHandle.KillCause() error + ErrCriticKill: the executor now distinguishes
an explicit critic KILL from a natural backstop expiry. runCtx uses a
cause-carrying cancel (WithCancelCause + a MaxRuntime timer cancelling with
DeadlineExceeded); the deadline-watch cancels with ErrCriticKill when
KillCause()!=nil, else DeadlineExceeded. statusFor reads context.Cause →
killed / timeout / cancelled are now distinct (were all "cancelled"). The
battery sets killCause from Decision.KillReason on a Kill.
Tests: statusFor "killed" case (cause=ErrCriticKill, err=Canceled); fake handle
+ battery RecordStep/KillCause signatures. Core stays battery-free.

Prerequisite for a full-fidelity mort agentcritic adapter (which adjusts a
healthy-but-long run's iteration budget, not just its deadline). executus's
CriticHandle was deadline+steer only; this adds the dynamic step ceiling above
an unchanged majordomo (which already exposes WithMaxStepsFunc).
- run.RunInfo += MaxIterations (the run's base ceiling, so a critic can raise it
relative to the baseline).
- run.CriticHandle += MaxSteps() int — polled by the executor each step via
agent.WithMaxStepsFunc; <=0 defers to the base. The executor uses
WithMaxStepsFunc(critic.MaxSteps) when a critic is active, else WithMaxSteps.
- critic battery: handle.maxSteps (initialised from RunInfo.MaxIterations) +
MaxSteps(); Decision gains RaiseStepsBy so an Escalator can raise the ceiling
alongside ExtendBy. ExtendOnce default is unchanged (time-only).
Test: a critic returning MaxSteps=5 lets a base-MaxIterations=1 run complete two
tool-dispatch steps past the base ceiling. Core stays battery-free (run doesn't
import critic).

majordomo's step observer fires post-iteration, so the critic's activity clock
refreshes per-iteration, not mid-tool — a single long tool call won't refresh it
until it returns. Documented + the host-progress-bridge mitigation (mort's
pattern). A true pre-dispatch hook needs majordomo support (follow-up).

From PR #9 (minimax + deepseek):
- Run now has a top-level recover() — the "never propagates a panic" promise was
unenforced; a panicking host Port (Critic/Audit/Palette) on the run goroutine
now becomes Result.Err instead of unwinding into the caller.
- The critic deadline-watch goroutine recovers panics from a host Deadline()
(it's a separate goroutine, so Run's recover can't catch it) — a buggy
CriticHandle can't crash the process.
- CriticHandle interface documents its concurrency contract (Record*/Steer on the
run goroutine vs Deadline()/Stop() from the watch goroutine — impls must be
concurrent-safe; the critic battery already is).
- startCritic's dead `soft <= 0 -> noop` guard (withFallbacks already coerces to
90s) replaced with a defensive inline 90s default, so a bypass of withFallbacks
still gets a working critic instead of silently none.
- Delivery tests made honest: the old "error path" test only checked the
early-return (no delivery); added TestDeliverErrorOnRunFailure (in-loop model
error -> DeliverError to the target) + renamed the early-return test.
Graded all #9 findings in the gadfly MCP.

Continues finishing the executor's run.Ports wiring (after C0's Palette).
Critic (run/critic.go): when Ports.Critic is set and the agent enables it, the
executor calls Monitor at run start, feeds RecordStep/RecordToolStart from the
step observer, drains the critic's Steer messages into the loop via
agent.WithSteer, and binds the run's hard cancellation to the critic's
(extendable) Deadline through a watch goroutine — a healthy-but-slow run gets
room while a hung one is killed. Stop() on run end. Soft timeout from
Defaults.CriticSoftTimeout (default 90s). nil-safe: no critic / not-enabled =
no-op.
Delivery (run/executor.go deliver): after the run, when Ports.Delivery is set
and inv.DeliveryID is non-empty, the executor posts Result.Output (or
DeliverError on failure) to a host-interpreted deliver.Target
{inv.DeliveryKind, inv.DeliveryID}. Empty target = caller reads Result.Output
itself (the synchronous default; the `.agent run` canary). Best-effort +
detached.
tool.Invocation gains DeliveryKind/DeliveryID (host-set egress target).
Tests: critic monitored/fed/steered/stopped when enabled, untouched when not;
delivery posts on a target, skips without one. Deferred: Checkpointer (needs a
majordomo hook to snapshot the running message history).

From the PR #8 review (all graded in the gadfly MCP):
- skip empty palette names + dedupe by final tool name, instead of producing a
"skill__" tool or an opaque box.Add duplicate error.
- delegationResult: no trailing blank line when a non-ok child produced no output.
- delegationErr: fold a child's partial output into the hard-failure error so it
isn't silently dropped.
Deferred to C0b (design-level, not trivial): route delegation through the
tool.Registry gate/audit wrappers; expose the skill's real input schema to the
LLM instead of a generic inputs map. typed-nil PaletteSource is left as a caller
contract (the == nil guard catches the untyped-nil interface).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The first cutover prerequisite: the executor now turns an agent's SkillPalette /
SubAgentPalette into delegation tools so a mort agent that delegates works
through run.Executor (the piece the `.agent run` canary needs beyond the
already-wired audit/budget).
- run/palette.go: addDelegationTools builds a skill__<name> tool (structured
inputs) per SkillPalette entry and an agent__<name> tool (prompt) per
SubAgentPalette entry, each invoking run.Ports.Palette as a CHILD of the
current run (parentRunID = inv.RunID, inheriting caller + channel). A non-ok
child status is surfaced to the parent with the partial output. nil-safe: no
PaletteSource or empty palette → no delegation tools (unchanged behavior).
- executor.go: call it right after building the low-level toolbox.
Tests: the model calls skill__helper → routed through Palette with the right
name/caller/inputs/parent; nil palette → run still works.
Deferred to C0b (the remaining run.Ports executor wiring): Critic (soft-timeout
monitor + deadline binding + steer), Delivery (output egress for surfaces that
need executor-side delivery), Checkpointer (needs a majordomo message-history
hook to snapshot resumable state). The `.agent run` canary delivers its returned
Result.Output itself, so these aren't on its critical path.

Independently verified all 18 gadfly findings against the code (18-agent
fan-out). Fixed the 9 real ones; the other 9 were false-positive /
hallucinated / valid-tradeoff (no change).
High:
- F1 nil model: a Models resolver returning (ctx,nil,nil) flowed into the
agent loop and nil-panicked. Now a clean error (Run never panics). +test.
- F9 compactor data-leak: renderTranscript sent tool-call args verbatim to
the summarizer (a possibly-different provider/tier); secret-bearing tool
args (mcp_call/email_send/http_*/webhook_*) are now redacted, with a doc
note that result bodies still flow (summary needs them).
Medium/minor:
- F2 compactor error path returned the folded slice, not the original msgs
(contradicting the documented non-fatal contract) -> return msgs.
- F3 RunStats.Status only ok/error; now timeout (DeadlineExceeded) /
cancelled (Canceled) via statusFor. +test.
- F4 step-zip emitted empty-name "ghost" steps when results>calls; now pairs
min(calls,results) only.
- F5 SetIteration was never called -> RunState.Iteration always 0; the step
observer now updates it each loop.
- F6 matchPending fallback was LIFO; now FIFO (matches the per-key queue).
- F7 estimateTokens had no default arm (future Part kinds counted as 0);
unknown parts now counted conservatively.
- F8 cloud_sync silently truncated >1MiB responses -> opaque JSON error; now
a clear "response exceeded N bytes" via readCapped.
- F12 step observer captured the caller ctx; now the merged runCtx.
- F13 compaction onFire was nil (doc claimed it logged); now wired to
audit LogEvent("compaction_fired").
- F11 (no pre-dispatch hook in majordomo) documented honestly as a known
limitation; F18 UsageSink doc clarified cache tokens are subsets of input.

The capstone of the run kernel: run.Executor.Run(ctx, RunnableAgent, inv)
ties model resolution + the tool registry + majordomo's agent loop +
context compaction + run-bounding + step/audit instrumentation into one
path, with every host concern behind the nil-safe run.Ports.
- run/executor.go: New(Config{Registry, Models, Defaults, Ports, Compactor,
ContextTokens, SystemHeader}) + Run -> Result{RunID, Output, Steps, Usage,
Err}. Budget gate (pre-run), model resolve, Audit StartRun/recorder
(satisfies RunTally, stamped on inv.RunState), toolbox build, step observer
(zips tool calls/results -> emitter + recorder.OnStep/OnTool), V10
detached-MaxRuntime context with caller-cancel merged back, compaction wired
from ContextTokens×ratio, audit Close + Budget Commit on a detached cleanup
ctx. Zero Ports = a bounded in-memory run (gadfly's case).
- run/executor_test.go: hermetic end-to-end run against majordomo's fake
provider (hello-world), Budget-rejection (no model call), Audit-port wiring
(StartRun + Close with terminal status/output). All green under -race.
- examples/minimal upgraded to the real "hello, agentic world" (~15 lines:
Configure tiers -> run.New -> Run -> print). README/CLAUDE.md updated.
Remaining P2 follow-ups (incremental): wire Critic/Checkpointer/PaletteSource/
Delivery into the loop, multi-phase Pipelines, and the no-tools direct path.

- compact/compactor.go: the per-run stateful context compactor (token-threshold
gate, fast-tier middle summarisation, fold memory) lifted from mort's
skillexec/compactor.go. Self-contained; its only dependency is a ModelResolver
func (model.ParseModelForContext satisfies it) + a token threshold.
- run/steps.go: the step-emission/instrumentation (stepEmitter, tool->kind/
summary mapping with redaction, Result.Steps accumulation) from agentexec,
repointed onto executus/tool.
Both build green. With the run-loop mechanics, RunnableAgent DTO, run.Ports,
compactor, and step instrumentation now all in place, the remaining P2 work is
the run.Executor itself (wiring these + majordomo's agent loop), which makes
executus runnable.

Add run/ports.go: the host seams the executor will consume, every one
nil-safe so a light host runs with the zero Ports (no persistence/audit/
budget/critic/delegation/delivery) and a heavy host wires each to a battery.
Ports mirror mort's existing interfaces so the batteries implement them
directly:
- Audit + RunRecorder (mort skillaudit.Storage/Writer): StartRun -> per-run
recorder (OnStep/OnTool/LogEvent/Close), recorder satisfies RunTally.
- Budget (mort skillexec.BudgetTracker): Check / Commit.
- Critic + CriticHandle (mort agentcritic): Monitor -> handle with
RecordStep/RecordToolStart/Steer/Deadline/Stop (the loop wiring finalizes
with the executor merge).
- Checkpointer (mort agentexec.RunCheckpointer): Save/Complete/Fail.
- PaletteSource (mort SkillInvokerForPalette + AgentInvokerForPalette):
Resolve/Invoke skill + agent delegation.
Plus host-neutral RunInfo / RunStats.
This completes the P2 inversion DESIGN; the agentexec+skillexec ->
run.Executor merge that consumes these Ports is the remaining P2 work.

Stand up the executus/run kernel foundation, decoupled from mort:
- runengine.go: the shared run-loop scaffolding (MergeCancellation,
CleanupContextTimeout, RunFinalizer/FireFinalizers, RunStateAccessor) moved
from mort. The accessor's *skillaudit.Writer dependency is inverted to a
narrow run.RunTally interface (TokenStats + ToolCallsCount) — the kernel
reads live tallies without importing the audit battery.
- submit.go: the legacy submit-capture compat tool (stdlib + majordomo/llm).
- agent.go: RunnableAgent DTO — the kernel's view of "a thing to run" (tier,
prompt, caps, palette, phases, critic config). The persona Agent and saved
Skill will LOWER into this DTO so the kernel never imports a noun battery.
This is the spine of the agentexec.Run(*agents.Agent) inversion.
run/ builds with only majordomo + executus/tool. The executor merge
(agentexec+skillexec -> run.Executor) and the nil-safe run.Ports
(Audit/Critic/Budget/Checkpointer/PaletteSource) are the next P2 block.

Batteries-included agent-harness base, extracted from mort's agent layer.
This first cut establishes the module + the zero-coupling core primitives:
- lane, dispatchguard, pendingattach, run/progress.go: moved verbatim from mort
- config: host config Source seam + env-var default (nil-safe helpers)
- deliver: output-egress seam + Discard/Stdout defaults
- identity: AdminPolicy + MemberResolver seams (nil-safe)
- fanout: programmatic N×M swarm (bounded global + per-key concurrency)
- README/CLAUDE.md with the vibe-coded banner; CI with Go gates +
the "core stays majordomo+stdlib only" invariant
Core builds with stdlib only today; majordomo enters at P1 (model/structured).
go build/vet/test -race all green.
