ZacharyZhang-NY 02cf5deebd 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.

# Kigi — agent/developer notes
Single source of truth for how this repository is organized and the
constraints every change must respect. Update this file whenever the tech
stack or product direction changes.
## What this is
Kigi is an unofficial Kimi Code CLI community build: a hard fork of
xai-org/grok-build (Apache-2.0, Rust) re-targeted at the Kimi Code
subscription API and the Moonshot open platform. It coexists with the
official `kimi` CLI: binary `kigi`, config dir `~/.kigi`
(`KIGI_SHARE_DIR` override), keyring service `kigi`, env prefix `KIGI_*`.
Never read or write `~/.kimi` (except the explicit one-time read-only
import) or any `KIMI_*` env var.
## Hard constraints
- **Zero egress**: outbound connections are limited to
`auth.kimi.com`, `api.kimi.com`, `api.moonshot.cn`, `api.moonshot.ai`,
GitHub Releases domains, and user-configured MCP servers. No telemetry,
no analytics, ever. `crates/codegen/kigi-env` is the single home of
first-party endpoints.
- **Toolchain**: Rust 1.97.0 (rust-toolchain.toml), edition 2024.
- **Gates** (all must stay green):
`cargo check --workspace --all-targets`,
`cargo clippy --workspace --all-targets` (zero warnings),
`cargo fmt --all --check`, `cargo deny check advisories`.
- **Observability is local**: `kigi-log` (unified session log, `--debug`
firehose, subsystem file logs, opt-in instrumentation) writes under
`~/.kigi` only. Its zero-network property is a contract.
- The root `Cargo.toml` is hand-maintained (upstream's generator is not in
this repo). Members sorted; versions inherited from
`workspace.package.version` (0.1.0).
## Layout
- `crates/codegen/` — the bulk of the application (62 `kigi-*` crates).
Key ones: `kigi-bin` (binary `kigi`), `kigi-tui` (full-screen TUI +
headless `-p` mode + `acp`/`mcp` commands), `kigi-shell` (agent runtime,
leader-follower IPC, sessions), `kigi-sampler` (inference client;
ChatCompletions/Responses/Messages backends), `kigi-auth` (credentials),
`kigi-config` (config layering, `~/.kigi` paths), `kigi-env` (endpoints),
`kigi-tools` (tool implementations incl. codex/opencode ports — see its
THIRD_PARTY_NOTICES.md), `kigi-workspace` (FS/VCS/exec/permissions,
checkpoint/worktree), `kigi-log` (local observability).
- `crates/common/`, `crates/build/`, `prod/mc/` — shared libs, proto build,
proxy wire types (the latter to be redefined against Kimi in M1).
- `third_party/` — vendored Mermaid rendering stack (untouched policy).
- `bin/protoc` — dotslash launcher used by proto codegen.
## Storage discipline
- Tests that touch the filesystem MUST use `tempfile::TempDir` (drop
cleans up) — never bare `std::env::temp_dir()` + `create_dir_all`,
which leaks directories into the OS temp root forever.
- `target/` grows past 150GB across repeated full-workspace builds
(incremental is already off); run `cargo clean` when it exceeds
~50GB and at milestone boundaries.
- Graph node worktrees are removed right after a successful merge-back;
only FAILED nodes keep theirs for postmortem.
## Test seams
Cross-crate test hooks are behind the `test-support` cargo feature
(kigi-workspace, kigi-pager-render, kigi-config, kigi-tui), enabled via
dependents' `[dev-dependencies]`. Don't expose new test seams as plain
`#[cfg(test)]` items across crate boundaries.
## Graph mode (`/graph`, post-0.1.x — plan.md in the parent dir)
A deterministic DAG scheduler layered over the goal engine: `/graph
<objective>` decomposes the objective into nodes (graph planner subagent
→ Agentproof-style static gate in `graph_plan.rs`), then executes each
node as one ordinary goal — the agentic loop lives INSIDE the node; the
edges stay deterministic Rust. The harness appends a terminal
`gn-final` verification node depending on every planner node.
- Feature flag `KIGI_GRAPH=1` (default off); availability additionally
requires the goal harness (`BuiltinGate::Graph`).
- Key modules (kigi-shell): `session/graph_tracker.rs` (pure state
machine; reuses `GoalStatus`/`GoalPhase`/`GoalPauseReason`),
`session/graph_plan.rs` (planner-JSON contract + validation + fnv id
canonicalization), `session/graph_planner.rs` (planner runner, reuses
the goal planner spawn plumbing),
`session/acp_session_impl/graph.rs` (orchestration seam).
- Seam points: `handle_prompt` intercepts GraphSet/GraphResume; the
in-turn loop's `EndTurn` arm calls `run_graph_round_end()` to advance
nodes within the same turn; goal auto-pauses cascade to the graph in
`auto_pause_goal_if_active_inner`; node goals are armed with the
REMAINING graph budget so `enforce_goal_token_budget` cascades trips.
- Persistence: `PersistenceMsg::GraphModeState(Option<..>)`
`<session_dir>/graph/state.json` (`None` tombstones after clear);
immutable per-version baselines `graph/graph.baseline.v{N}.json`;
per-node goal artifacts archived to `graph/<node_id>/`. Restore
demotes `Active``UserPaused` and `Running``Ready` (re-run is safe:
the verifier gates completion).
- `/goal` and `/graph` are mutually exclusive while the graph owns the
engine; e2e suite: `acp_session_tests/graph/graph_e2e_tests.rs`.
- Parallel fan-out (G1): with `KIGI_GRAPH_CONCURRENCY > 1` (default 3,
clamp [1,8]) and ≥2 `Ready` nodes, `drive_graph` runs batches via
`acp_session_impl/graph_workers.rs` — per node a bounded
worker↔verifier subagent loop (`KIGI_GRAPH_NODE_ROUNDS`, default 3;
`general-purpose` children; worktree isolation on round 1, resume
keeps context+worktree on later rounds; `NODE_RESULT:` /
`NODE_VERDICT:` terminal contracts parsed fail-closed), then
SEQUENTIAL merge-back via `kigi_workspace::worktree::apply_worktree`
(`ApplyMode::Merge`); a conflict fails the node and blocks its
dependents while other chains continue. `gn-final` always runs
serially on the full goal engine. Concurrency=1 is byte-identical to
the serial G0 path. Ceiling: a worker round exceeding the foreground
subagent await budget (600s) is cancelled and retried via resume.
- G2: `BudgetLimited` is resumable — a budget trip demotes in-flight
nodes to `Ready` (resource stop, not a verdict) and
`/graph resume --budget <tokens>` re-arms with fresh headroom. The
pager shows a graph status chip driven by the `GraphUpdated` wire
variant (`extensions/notification.rs`), emitted from the single
`persist_graph_state` chokepoint (checkpoint ⇔ badge tick); old
pagers degrade via `#[serde(other)] Unknown`. PTY scenarios:
`graph_slash_presession{,_disabled}.yaml`.
- G3: dynamic replan. `DISCOVERED: <text>` line markers (fence-stripped,
placeholder-filtered) from workers/verifiers/the serial node's final
text queue as `pending_discoveries`; at each dispatch boundary
`maybe_replan_graph` (`acp_session_impl/graph_replan.rs`) runs a
replanner subagent producing an APPEND-ONLY appendix
(`validate_replan`: existing-id deps allowed, edges onto `gn-final`
rejected — they would cycle after the final-gating extension),
bumps `plan_version`, freezes `graph.baseline.v{N}.json`, and regates
`gn-final` (Ready→Waiting). Bounded by `KIGI_GRAPH_REPLAN_CAP`
(default 3, 0 = off); past the cap — and after the final node has
achieved — discoveries drain to history only. Replan failure degrades
(history + notice); it never pauses a working graph.
- G4: the graph follows the repo. Every checkpoint projects to
`.kigi/graph.jsonl` at the git root (`session/graph_project.rs`,
header line + one node per line, atomic write); single writer via an
fs2 flock sidecar; other instances get read-only `/graph status`.
Fresh sessions revive via `/graph resume` (load UNDER the lock,
from_snapshot demotions apply). All lock-then-mutate sites
identity-check the projected `graph_id`; kigi never commits the file.
- G5: `/graph show` renders box-drawing DAG art
(`session/graph_render.rs`, Sugiyama-lite: longest-path layers, dummy
pass-throughs, barycenter ordering, bus lanes). Wider than 120 cols
degrades to the status tree.
- G6: plan-boundary topology optimizer
(`acp_session_impl/graph_optimize.rs`; `KIGI_GRAPH_OPTIMIZER=0`
disables). Restricted ops (`remove_dep`/`reorder`/`merge`/`split`)
validated by `graph_plan::apply_optimization`: pending-only targets,
immutable nodes byte-identical in the result, terminal gate rebuilt,
whole-graph acyclicity. Applied passes bump `plan_version` and share
the replan cap; `{"ops": []}` is a respected free no-op; failures
degrade.
## Milestones (PRD §8.3)
- M0 (done): rename, deletions (voice/telemetry/announcements/marketplace/
relay-gateway), toolchain, gates.
- M1: Kimi device-flow auth (F1), Moonshot API-key channel (F2), inference
via ChatCompletions (F3), dynamic model sync (F4). The auth stack in
`kigi-shell/src/auth` + `kigi-auth` gets rewritten here; transitional
grok.com references live only there and in `kigi-sampler`/proxy types.
- M2: server-side search/fetch (F5), command parity with kimi-cli 1.49.0
(F6), one-time `~/.kimi/config.toml` import (F7), F9 smoke list, perf CI.
- M3: GitHub Releases distribution, install scripts, self-update (F8).
