Add /graph G6: plan-boundary topology optimizer
A restricted optimizer pass now reviews the graph at plan boundaries —
right after initial planning and piggybacked on each replan version
boundary, never mid-execution. An optimizer subagent may emit four ops
over Waiting/Ready nodes only: remove_dep (delete a false dependency,
restoring parallelism — the highest-value edit), reorder (pending
priority for the serial scheduler), merge (fold two tiny nodes; specs
concatenate, deps union, dependents re-point, absorbed self-deps drop),
and split (2-3 focused replacements inheriting the original's deps and
dependents). The optimizer changes graph DATA only; the executor stays
pure deterministic Rust. KIGI_GRAPH_OPTIMIZER=0 disables it entirely.
apply_optimization enforces the contract twice: per-op checks
(pending-only targets, known ids, terminal node untouchable, dead-node
deps rejected as DeadDep, merge/split targets with non-pending
dependents rejected with the true reason instead of tripping the
immutable invariant later), then FINAL invariants — every non-pending
node byte-identical in the result, the gn-final gate rebuilt over all
survivors, node cap, whole-graph acyclicity, and a BIDIRECTIONAL status
re-derivation for pending nodes (adversarial review caught the critical
hole: a merge grafting unsatisfied deps onto a Ready node would
otherwise dispatch it ahead of its new prerequisites, since
recompute_ready is promote-only). Applied passes bump plan_version,
freeze an immutable baseline, and consume a slot of the SHARED replan
cap; an explicit {"ops": []} is a respected free no-op; any failure
degrades to keeping the current plan. Plumbing reuses a new shared
artifact-pass runner (stale-artifact delete, size cap, missing-file
fail-closed) extracted from the replanner.
Tests: remove_dep parallelism restore + loud no-such-dep, immutable and
terminal-node rejections across all four ops, merge/split dependent
rewiring incl. final-gate rebuild and intra-split dep resolution,
result-cycle rejection, dead-dep splits, Ready-demote-on-merge, and
three e2e flows — false-dep removal proven ACTUALLY parallel by the
held-reply fan-out gate, OPTIMIZER=0 spawning zero passes, and the
shared-cap guard. kigi-shell 4959 lib tests green; clippy clean.

Add /graph G3: dynamic replan from DISCOVERED work items
Workers, verifiers, and serial node goals can now surface out-of-scope work
as line-anchored 'DISCOVERED: <text>' markers (fence-stripped and
placeholder-filtered — the templates' own examples are fenced so verbatim
echoes never parse; worker summaries embedded in verifier prompts get the
marker neutralized alongside NODE_RESULT/NODE_VERDICT). Discoveries queue on
the orchestration as persisted state and fold into the graph at dispatch
boundaries: a replanner subagent produces a strictly APPEND-ONLY appendix,
validated against the live graph (existing-id deps allowed; edges onto
gn-final rejected — they would cycle the moment the final-gating extension
lands; Blocks deps on Failed/Blocked nodes rejected as DeadDep so the
attempt-2 feedback loop repairs the artifact). Installing an appendix bumps
plan_version, freezes an immutable graph.baseline.v{N}.json next to the
prior versions, extends gn-final's gate (demoting a Ready final back to
Waiting), and recomputes readiness.
DiscoveredFrom edges are audit metadata, never scheduling gates: an origin
is always terminal at replan time, so gating on it is either a no-op or a
permanent wedge — and a failed node's discoveries are still real work.
Replanning is bounded by KIGI_GRAPH_REPLAN_CAP (default 3; 0 disables it
quietly): past the cap, after the final node has achieved, or on replan
failure, discoveries drain to history only — a working graph is never
paused for a failed enhancement pass, and it always converges. The budget
gate now precedes the replan boundary (a budget-dead graph keeps its
discoveries queued for a later --budget top-up instead of spending two
replanner runs first), and both planner runners delete stale artifacts
before spawning so a child that responds without writing can never get a
previous pass's file validated as its own output.
Tests: validate_replan unit coverage (existing-id resolution,
DiscoveredFrom dedup, collisions, dead deps vs dead origins, terminal-node
edges, combined-graph cycles), tracker appendix/regate/audit-edge tests,
and two e2e flows — discovery → replan → appended node runs to Achieved
with both baselines frozen, and cap-0 draining to history while the graph
still converges. kigi-shell 4935 lib tests green; workspace clippy clean.

Add /graph G0: serial graph engineering mode over the goal engine
A deterministic DAG scheduler layered on the existing goal engine: /graph <objective> decomposes the objective via a graph-planner subagent, gates the result through Agentproof-style static validation (cycles, unknown deps, duplicate slugs, caps), appends a structural final-verification node, then executes each node as one ordinary goal — planner, worker loop, adversarial verifier, budget and pause machinery all reused verbatim. The in-turn loop advances nodes within the same turn (multi-loop closed loop); goal-side auto-pauses cascade to the graph at a single chokepoint; node goals are armed with the remaining graph budget so mid-node overruns trip graph-wide. Gated by KIGI_GRAPH=1 (default off) + the goal harness. State persists to <session_dir>/graph/state.json with a clear-tombstone; per-version immutable baselines and per-node artifact archives live under graph/<graph_id>/. Restore demotes Active->UserPaused and Running->Ready (verifier-gated re-run). Review hardening (adversarial multi-agent pass, 24 confirmed findings fixed): the goal-inactive loop break now consults the graph seam (mid-turn classifier-disabled completions can no longer strand an Active graph), the pause cascade fires even when no node goal is in flight (cancel during planning), node bookkeeping precedes the long setup await, /graph clear only resets the engine it owns, budget trips terminally fail the in-flight node, and the pause transitions in /goal pause + /graph pause no longer hide inside debug_assert! (a release-build no-op inherited from upstream). Tests: 4908 kigi-shell lib tests green, including a serial 4-node closed-loop e2e, restore/resume, cascade, mutual-exclusion, planning-retry, persistence round-trip + tombstone, and status rendering. |
