From a1b963776e3de61efeaf5d4f28ae2140f2c035fc Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 6 Jul 2026 02:11:03 +0000 Subject: [PATCH 01/53] =?UTF-8?q?feat(workflows):=20orchestration=20engine?= =?UTF-8?q?=20=E2=80=94=20IR=20compiler,=20extended=20grammar,=20native=20?= =?UTF-8?q?executor,=20akm=20workflow=20run?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements P0 + P1 of docs/technical/akm-workflows-orchestration-plan.md, plus the open P0 hygiene items: - IR: Workflow Plan Graph (src/workflows/ir/schema.ts, compile.ts). Linear workflows compile to one agent node + gate per step — no behavior change; fan-out steps compile to a map node with collect/vote reducers. - Extended Markdown grammar: ### Runner / Model / Timeout / Fan-out / Schema / Env / Depends On step subsections (parser-orchestration.ts), additive and backward-compatible, errors accumulated; Depends On ids validated in validator.ts. - Persistence: migration 004 workflow_run_units (+ failure_reason), unit CRUD on WorkflowRunsRepository, serialized writer queue (exec/unit-writer.ts) so N parallel unit completions never contend on SQLite's single writer. - Native executor (exec/native-executor.ts): fan-out via a scheduler built on concurrentMap (cap min(16, cores−2), lifetime unit cap, per-unit timeout default 10m), schema-validated structured output via the runStructured core + a bounded JSON-Schema-subset validator (core/json-schema.ts), unit preamble asset, env bindings through the akm env run machinery extracted to env-binding.ts (secret tokens, dangerous-key policy, keys-only audit), workflow_unit_* events. - Engine loop (exec/run-workflow.ts) + `akm workflow run` CLI: advances the gated spine strictly through completeWorkflowStep; gate rejections stop the engine and surface corrective feedback. Marked experimental in STABILITY.md. - Hygiene (check-in review C2/M1): plain-text formatters render the CONTINUE directive; every run-detail response evaluates the check-in; validator error message lists name/updated; removed the phantom `workflow step` alias from docs. - Model tiers: new `fable` built-in alias (claude-fable-5 / opencode/claude-fable-5); docs recommend fast/balanced/deep tiers with deep → fable.

All template replacements now use function callbacks. - `akm workflow run` on a failed/blocked run dispatched the terminal step's units (real cost) before completeWorkflowStep's preflight threw. The engine now refuses non-active runs before any dispatch. - The llm runner ignored per-unit timeout, abort signal, ### Model, and native structured output; chatCompletion now receives timeoutMs (### Timeout none → max 32-bit delay), signal, responseSchema, and a model override resolved through the global alias tiers. - The lifetime unit cap reset per invocation; it is now seeded from the run's workflow_run_units journal so it is truly per-run. - ### Env bindings were silently dropped on sdk/llm runners (audit event fired, nothing injected). Units now fail loudly with env_unsupported; docs updated (env requires the agent runner). - Fan-out concurrency defaulted to the engine cap, violating the repo's local-model-first LLM-defaults rule; it now defaults to 1 and the cap only clamps. - Resume re-dispatched and clobbered completed unit rows; completed units with a matching input_hash are now reused from the journal (durable-row resume at unit granularity). - ### Depends On was parsed and validated but never consulted; the engine now asserts dependencies are completed/skipped before dispatching a step.

Two further defects independent of +determinism: the completion gate judged an engine-generated summary +("Executed 3 units…") instead of the work, and no failure policy existed +despite `failure_reason` being persisted expressly to enable one. The +markdown grammar was meanwhile accreting program semantics (routes, gate +loops, data flow) one subsection at a time — becoming a bad programming +language instead of either staying simple or being a real one. + +### Owner decisions (recorded verbatim, supersede conflicting text above) + +1. **Direction → program format, YAML.** Orchestrated workflows are a + deterministic orchestration *program* expressed in **YAML** (chosen over + markdown for lintability/parseability — a published JSON Schema in + `schemas/` validates it, and `akm workflow validate` lints it). The + durable, gated step spine remains the organizing principle; YAML is how + the program is written, not a change to what a run is. +2. **Determinism bar → full replay semantics.** The compiled plan is frozen + per run; orchestration decisions are pure functions of (frozen plan, + params, journaled unit results). No wall-clock, randomness, or ambient + lookup exists in the expression language *by construction*, so a resumed + run is byte-reproducible in every decision the engine makes. The only + nondeterminism is inside agent/LLM calls — and those are journaled. +3. **Rework scope → break the P1 surface freely.** The P1 markdown + orchestration subsections (`### Runner`/`### Fan-out`/`### Schema`/ + `### Route`/…) are **removed**, not kept alongside (they were shipped + experimental and unreleased). Classic **linear markdown workflows remain + fully supported and unchanged** — they compile to a linear plan exactly + as today (that CLI contract is stable). `workflow.db` evolution stays + strictly additive; migrations 001–005 are untouched. +4. **Failure policy → explicit surface, fail-fast default.** Per-unit + `on_error: fail | continue` and bounded `retry` (keyed on the persisted + `failure_reason` taxonomy). The default remains fail-fast so nothing + silently degrades. + +### The YAML workflow format (v1 sketch — normative schema ships in R1) + +```yaml +version: 1 +name: review-changes +description: Review changed files and route the outcome +params: + changed_files: { type: array, items: { type: string } } +defaults: # run-level defaults, overridable per unit + runner: sdk # llm | agent | sdk | inherit + model: balanced + timeout: 10m + on_error: fail + +steps: + - id: discover + title: Discover targets + unit: + instructions: | + List the files that need review for ${{ params.changed_files }}. + output: # TYPED step artifact (JSON Schema) + type: object + properties: { files: { type: array, items: { type: string } } } + required: [files] + gate: + criteria: [every target is listed] + + - id: review + title: Review files + map: + over: ${{ steps.discover.output.files }} # EXPLICIT producer address + concurrency: 8 + reducer: collect + unit: + runner: agent + profile: reviewer + model: deep + timeout: 5m + retry: { max: 1, on: [timeout, llm_rate_limit] } + on_error: continue + instructions: | + Review ${{ item }} for correctness bugs. + output: { type: object, properties: { file: { type: string }, verdict: { type: string } }, required: [file, verdict] } + output: # step artifact produced by the reducer + type: object + properties: { verdict: { type: string } } + gate: + criteria: [every changed file has a verdict] + max_loops: 2 # evaluator-optimizer, bounded + + - id: triage + route: # routing on an EXPLICIT input + input: ${{ steps.review.output.verdict }} + when: { pass: ship, fail: rework } + default: manual-triage +``` + +**The expression language is the whole trick.** `${{ … }}` references are +*parsed*, not string-replaced: a closed grammar of `params.`, +`steps..output.`, `item`, `item_index` — nothing else.

Every + subsequent invocation executes the frozen plan; the source file is never + re-read for an in-flight run. Re-planning is an explicit new run. +- **Journal + replay.** Unit identity is **content-derived**: + `unit_id = :` (`:solo` for + non-fan-out), so identity survives list regeneration and reordering. A + completed journal row with matching `input_hash` IS the result on replay; + same identity with a different hash is a **replay divergence error** + (impossible under a frozen plan unless the journal was tampered with — + fail loudly, never silently re-run). Failed/missing units dispatch live. + Gate evaluator calls are journaled like units (they are LLM calls); + human gate approvals are never cached (a blocked gate stays blocked). +- **Typed artifacts, honest gates.** A step's `output` schema is validated + against the reducer result; the gate judge receives the **artifact** + (plus criteria), not engine-generated prose. `collect` produces the array + of unit outputs; `vote` produces the majority value; a step with no + `output` declaration carries its units' raw results as an untyped + artifact (permitted, but the validator warns). +- **Run lease.** The engine takes a lease (`engine_lease_until` + + holder id, migration 006) before dispatching and renews it while running; + a second `workflow run` on a leased run refuses up front. The manual + `next`/`complete` loop also respects the lease. +- **Failure policy.** `on_error: fail` (default) fails the step on the + first unit failure; `continue` records failures in the artifact and lets + the gate decide. `retry: { max, on: […] }` re-dispatches + transient failures (same unit identity, attempt counter on the row). +- **What carries over unchanged from P0–P2:** the gated spine and + `completeWorkflowStep` invariant, `workflow_run_units` + writer queue + + migrations, the scheduler caps, `runStructured` + the JSON-schema-subset + validator, the unit preamble, env bindings, model-alias tiers, and all + seven P2 harness adapters (the dispatch seam is untouched by this + redesign — only what feeds it changes). + +### What is deleted or replaced + +- **Deleted:** the P1 markdown orchestration subsections and their parser + (`parser-orchestration.ts` grammar surface), the evidence-search data + flow, positional unit ids, the synthetic step summaries, and the P5 + "replay as opt-in mode" design (full replay is now the *only* mode — + durable-row behavior is its degenerate case when the journal is empty). +- **Replaced:** the P3 Claude-Code-delegation backend (a compiler emitting + CC-proprietary `Workflow` scripts + report-back) is replaced by a + **harness-neutral driver protocol**: `akm workflow brief ` emits the + frozen plan's pending units + report contract as plain markdown/JSON; + *any* agent session (Claude Code, opencode, Codex, a human) executes and + reports via `akm workflow report`. CC becomes documentation, not a + compile target. The `min(16, cores−2)` cap becomes an akm config knob + (`workflow.maxConcurrency`) with a conservative default, not a CC + constant. +- **Still explicitly out of scope (owner):** the GitHub Copilot + coding-agent cloud delegate; the stash MCP server. + +### Revised phases (replace P3–P5) + +- **R1 — format + frozen plan.** YAML schema (`schemas/akm-workflow.json`) + + parser/linter (`workflow validate`), expression-language parser, + compiler to the (revised) IR, migration 006 (`plan_json`, `plan_hash`, + lease columns), plan freezing in `workflow start`/`run`.

Re-land the P4 features on this foundation: + budget ceilings, `workflow watch`, `isolation: worktree` (resolving SDK + seam decision 1 properly — server keyed by cwd — so isolation and env + bindings work on the DEFAULT runner), bounded gate loops. +- **R3 — driver protocol.** `workflow brief` + `workflow report` ingest + + unit-level check-in; the harness-neutral replacement for CC delegation. +- **R4 — hardening.** Cross-surface conformance (engine-driven vs + brief/report-driven runs must produce identical unit graphs), chaos + tests (crash/resume, lease contention, hostile content), docs, and the + status sweep of this document. From fa0267d7b38366af44818f6ebd63bf1d1761c2a6 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 6 Jul 2026 16:17:47 +0000 Subject: [PATCH 07/53] =?UTF-8?q?wip(workflows):=20R1=20checkpoint=20?= =?UTF-8?q?=E2=80=94=20expression=20language=20+=20YAML=20format=20landed;?= =?UTF-8?q?=20compiler=20mid-flight?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Paused snapshot of the R1 workflow run (wf_35e2cd58-5d6), resuming on a timer. State: - DONE (green, tested): src/workflows/program/ expression language (closed ${{ }} grammar, parsed AST, single-pass resolution) + program-expressions tests; schemas/akm-workflow.json + YAML program parser/validator (src/workflows/program/{schema,parser}.ts) + program-parser tests. - IN FLIGHT (agent died mid-task; will re-run on resume): src/workflows/ir/schema.ts is rewritten to IR v2, but ir/compile.ts and the executor still expect v1 — THIS COMMIT DOES NOT TYPECHECK. Migration 006 and asset plumbing not started. Do not build on this commit; the resumed workflow completes the compiler, frozen-plan, asset-plumbing, and engine-cutover phases.

charset=UTF-8 Content-Transfer-Encoding: 8bit Mid-run durability checkpoint of the resumed R1 workflow (wf_35e2cd58-5d6). Landed since fa0267d (compiler + frozen-plan phases, both green): - ir/schema.ts + ir/compile.ts at IR v2: compileWorkflowProgram (YAML, full expression validation, defaults merged at compile) and compileWorkflowPlan (linear markdown golden) both lowering to one plan graph; ir/plan-hash.ts canonical JSON + sha256. - Migration 006: plan_json/plan_hash + engine lease columns; setRunPlan in the repository; startWorkflowRun compiles and freezes the plan in the same transaction as the run insert; run-workflow executes the frozen plan with hash integrity check + legacy fallback. - ir-compile/conformance/migration tests rewritten for v2. Asset-plumbing agent still running; engine cutover pending — tree may not fully typecheck. Do not build on this commit.

charset=UTF-8 Content-Transfer-Encoding: 8bit R1 run wf_35e2cd58-5d6: the r1-core adversarial review returned 6 findings (4 actionable); the fix agent resolved all four at root cause with regression tests — notably a route-dispatch defect in run-workflow.ts and a `templating: verbatim|expressions` discriminator on IR agent nodes so linear-markdown instructions are never expression-parsed. Tree is green (tsc clean, 603 workflow/agent tests). The docs agent wrote its doc updates (CHANGELOG/STABILITY/workflows.md/ plan annotations) but died before journaling a result; it re-runs on resume, followed by the final verify + final review phases.

charset=UTF-8 Content-Transfer-Encoding: 8bit Closes R1 of the redesign addendum (run wf_35e2cd58-5d6). This commit lands the docs phase and the final whole-diff review's three confirmed fixes (7 regression tests): - Step-output contract: engine steps journal a promoted artifact under evidence.output (solo result/text; collect -> per-item array with null slots for on_error:continue failures; vote -> winner), and the exported projectStepOutput() is the single projection used by both the unit-template scope and route evaluation — so the documented ${{ steps..output. }} addressing resolves against real results end-to-end. Manual/pre-R1 evidence is exposed as-is. - Cascaded routing: a skipped router's own targets are marked skip-on-reach (live path AND journaled decisions on resume), so an unselected branch's downstream branch targets never dispatch and the skipped router's input is never resolved. - Lifetime unit cap is now consumed per ACTUAL journaled dispatch (retries included, durable-row reuses free) via a DispatchBudget in the executor; the pre-batch check that made large partially-completed fan-outs unresumable is removed. Capped steps fail hard regardless of on_error. Docs: workflows.md rewritten for the YAML program format (expression table, frozen-plan semantics, failure policy, step-output contract), STABILITY + CHANGELOG updated, plan addendum annotated R1 SHIPPED. Verified post-fix: biome clean (12 intentional template-literal warnings in test fixtures), tsc clean, unit 23780 pass / integration 735 pass with only the documented pre-existing failures.

Landed since aa1dbc7, tsc clean + 287 workflow tests green: - Typed artifacts: outputSchema validated against the promoted artifact before completion; artifact-judging gates (judge receives the artifact, canonical JSON clipped, not engine prose); gate evaluator calls journaled as unit rows (.gate:l); bounded gate loops (max_loops) with feedback threaded into re-run prompts, loop rows journaled as ~l. - Review r2-a: 5 findings, actionable ones fixed — notably the run-workflow !result.ok branch failing runs unconditionally, which broke on_error: continue semantics at the engine level.

This commit lands the final whole-diff review's confirmed fix plus the final-check's test relocation: - Budget-seed accounting: gate-evaluation journal rows (now stamped phase="gate" at insert) are excluded from the resume-time seed for budget.max_units and the lifetime unit cap — resumed runs no longer hit spurious "budget exceeded" failures from counting judge calls as dispatches. Discriminator is the phase column (step ids may contain dots, so a node_id suffix match could collide). Regression test proven to fail against the pre-fix code. - tests/workflows/worktree.test.ts moved unchanged to tests/integration/workflow-worktree-leftovers.test.ts: it spawns real git subprocesses, which unit scope forbids (lint-tests-isolation Rule 5); integration scope is the rule's own remedy. R2 delivered across this run (see the wip checkpoints for detail): content-derived unit identity + replay divergence, single-driver run lease, typed step artifacts + artifact-judged gates + bounded max_loops with journaled gate evaluations, budget ceilings, workflow watch + onEvent, SDK-per-cwd seam + worktree isolation + sdk env bindings. Verified: biome clean (12 intentional template-literal warnings), tsc clean, unit 24020 pass / integration 747 pass with only the documented pre-existing failures.

The runner now owns the spawn (createManagedOpencode; the SDK package is used only for createOpencodeClient): after the URL handshake the child and its pipes are unref'ed/destroyed, and close() sends SIGTERM with an unref'ed 2s grace timer escalating to SIGKILL.

Its single shared `timerCb` let the later drain-timer registrations clobber the wrapper-timeout callback, which then never fired — the hanging spawn wedged the test to its 30s limit. Fire each callback independently (matching the array-based fakes in the agent-spawn suites); no production change.
