feat(sdk): settle data and code gate contract

[kjgbot]

Summary

Closes issue #132 item 6 without adding an expression language or changing kernel vocabulary.

• classifies named verification data as kernel-evaluated, preflightable, and journal-replayable
• classifies author callbacks as runtime-only and never serializes the closure
• exposes the exact named gate plan in human and JSON flows check reports
• keeps v1 verification: lowering byte-for-byte unchanged
• settles SURFACE §6 on named checks only

Red-first evidence

Before sdk/src/gate-contract.ts existed:

Honest aggregate-run note

The first all-files SDK run had 242 passing tests and one 5-second timeout in the first live-kernel case while files ran in parallel. The complete live-kernel file then passed 17/17 alone as captured above; the remaining files passed 227/227 together. No mutation-verification claim is made.

📝 Walkthrough

Walkthrough

The change defines a shared gate contract, freezes JSON-compatible inputs, bounds recursive JSON Schema validation, adds preflight gate reporting, and rejects invalid declarations before kernel storage or execution.

Changes

Gate validation and schema-bound verification

Layer / File(s)	Summary
SDK gate contracts and input snapshots sdk/src/{json-value,canonical,spec,validate,compile,gate-contract}.ts, sdk/tests/*	The SDK snapshots inputs, validates gate types by step kind, lowers supported checks, rejects unsafe values, and exposes gate metadata.
Bounded JSON Schema validation sdk/src/{json-schema,json-schema-bound}.ts, kernel/relayflowd-core/src/schema.rs, testdata/*schema*, sdk/tests/json-schema-bound.test.ts	The SDK and kernel resolve references and reject unbounded same-instance cycles while accepting terminating recursive schemas.
Preflight gate inspection and reporting sdk/src/{preflight,cli,cli/check,failure-kinds}.ts, sdk/tests/{preflight,cli,dependency-validation,verb-field-lint}.test.ts	Preflight compiles before probes, returns gate plans, reports vacuous schemas, and maps compilation failures to invalid_spec.
Kernel declaration enforcement and replay kernel/relayflowd-core/src/{spec,verify,state/tests}.rs, kernel/relayflowd/src/{server,server/protocol}.rs, kernel/relayflowd/tests/invalid_schema_preflight.rs	Kernel startup rejects invalid schemas before journal creation, returns invalid_spec, and replays completed data-gate verdicts without rerunning completed steps.
Contract and verification records docs/*, ops/reviews/*	The gate contract, startup behavior, repair history, corpus coverage, verification results, and verification limits are documented.

Estimated code review effort: 5 (Critical) | ~120 minutes

Poem

A rabbit checks schemas by moonlight bright
Frozen fields rest in a neat little line
Cycles are bounded and gates name their way
Journals replay what was finished today
“Hop!” says the rabbit, “the checks now align”

Repair evidence for exact head 11ad3e2da7f473fefe1e9e0b44b599890b9de073.

The repair closes four public-boundary holes without adding a gate language: exit_code is deterministic-only, author input is copied into frozen behavior-free JSON before validation/lowering, boolean schemas match the kernel, and exported preflight() compiles before probing or inspecting. inspectStepGate is no longer a public raw-input API.

Fresh REVIEW_FAILED repair evidence for exact pushed head f5b8437b41e32d7ba45bb96eecf9bf8eb2aee65a.

Product changes:

• reject Proxy values through Node/Bun's trap-free proxy brand check before prototype/key/descriptor reflection;
• omit explicitly undefined object properties, matching JSON, exactOptionalPropertyTypes: false, validateSpec, and v1 compilation while retaining strict array handling;
• preserve the typed SpecError cause from Engine::start and map semantic run.start validation failures to protocol invalid_spec;
• replace the in-process invalid-schema test with a real Unix-socket hello → run.start test asserting no command, registry, or runs directory.

The exported unknown-input boundaries now snapshot/reject before reflection:

• validateSpec catches snapshot refusal and returns { ok: false, errors } without throwing.
• kernelToAuthoring snapshots before reverse lowering and translates snapshot refusal to CompileError.
• Both tests import through the public src/index.js export; reverse lowering uses a nested Proxy-wrapped steps array.

SIGNOFF A — FINDINGS (not an approval)

I reviewed exact head f5b8437b41e32d7ba45bb96eecf9bf8eb2aee65a against merge base a0d42ffbdc7fb60b42c0b5bea4f58408249b08a2.

P1 / F1: the claimed behavior-free SDK data boundary is incomplete. At that reviewed head, exported validateSpec accepts a valid Proxy after three ownKeys/descriptor traps and returns {ok:true}; exported kernelToAuthoring likewise executes three traps and returns normalized output. compileSpec correctly rejects the same Proxy at zero traps, which isolates the bypass.

File evidence: sdk/src/validate.ts:81-92 reflects input through Object.keys; sdk/src/compile.ts:187-324 has public kernelToAuthoring / requireKernelObject / assertKernelKeys reflecting an unknown; sdk/src/index.ts:31-40 exports both boundaries. Reproduced in Node, Bun, and a packed-and-installed @relayflows/sdk tarball.

Required repair: snapshot/reject before any reflection in both exported unknown-input boundaries (or make the reverse converter non-public and parsed-JSON-only), with Node, Bun, and packed-install regression coverage.

The PR now reports head e6210a2fc666df6dc8c777c009712ddf99efa877, which I have not reviewed; this verdict is pinned only to f5b8437b41e32d7ba45bb96eecf9bf8eb2aee65a and needs re-signoff after a fix. Full literal evidence is committed in ops/reviews/20260902-2140-pr139-signoff-structure.md.

Rebased onto main @ 3725025 — now 8b7148d

The branch was CONFLICTING and sat unmoved for ~12h (the codex agent assigned the rebase never pushed). Rebased all 12 commits myself.

Conflicts and how they were resolved

1. kernel/relayflowd-core/src/spec.rs — both sides added validation to the same step loop. Main (#137) added the surface-identity check; this branch added the JSON Schema check. They are independent if let blocks that happened to share a trailing brace, which is why git could not merge them. Both kept, surface check first.

2. kernel/relayflowd/src/server.rs — trap 1 (a moved definition). This is the dangerous one. Main moved decode_params, to_value, protocol_conflict, internal_error and error_response out of server.rs into server/protocol.rs as pub(super). This branch's commit re-added all of them to server.rs. Taking "both sides" would have produced duplicate definitions.

Verified per-function against main before resolving:

decode_params:    in main server.rs=0 ; elsewhere in main kernel=1
to_value:         in main server.rs=0 ; elsewhere in main kernel=1
protocol_conflict:in main server.rs=0 ; elsewhere in main kernel=1
internal_error:   in main server.rs=0 ; elsewhere in main kernel=1
error_response:   in main server.rs=0 ; elsewhere in main kernel=1
run_start_error:  in main server.rs=0 ; elsewhere in main kernel=0   ← genuinely new

So: took main's side wholesale, and relocated only run_start_error — the one function that is this branch's own — into server/protocol.rs as pub(super), adding the relayflowd_core::SpecError import there. server.rs does use protocol::*, so the call site at run.start is unchanged and still maps a SpecError to invalid_spec rather than internal. Main's import line was taken as-is; the build produces no unused-import warning, which is the check that the resolution is actually consistent rather than merely compiling.

Trap audit

The other three known silent-revert traps, each checked textually because each auto-merges with no conflict marker:

• timeoutMs deterministic-only — present in both the base spread and the allowlist (compile.ts:131, plus the timeout_ms lowering at 385/507).
• .map(toKernelTrigger) — survives at compile.ts:252; without it camelCase reaches a deny_unknown_fields kernel.
• step-fields.ts output — present on both llm and agent.

Verification at 8b7148d

kernel:  sh ops/cargo.sh test --workspace   → 142 passed, 0 failed
         (main is 130; this branch adds 12)
SDK:     vitest run                          → 561 passed, 3 skipped, 0 failed (26 files)

Diff against main in kernel/relayflowd-core/ is 750 insertions, 2 deletions — nothing of main's was silently dropped, which is the specific failure mode trap 1 causes.

One flake, reported not hidden

The first SDK run showed 1 failed, with:

Error: ENOENT: no such file or directory, open '.relayflow/backlog-picker-entry.json'

Two subsequent full runs were clean (561 passed). It looks like a test writing to a relative .relayflow/ path racing with another under vitest parallelism, rather than anything this rebase changed — but it is a real flake in the suite and now that #153 makes CI run all 26 files, it will surface there periodically. Worth a separate issue; I have not touched it here.

Note on the base

main moved under this work: #153 (ci: run the kernel and full SDK suites) merged mid-rebase, so I rebased again onto 3725025. This PR is the first to be judged by the full kernel + SDK suites rather than four named test files.

Still needs a fresh independent signoff at 8b7148d before merge — I did the rebase, so I am not the right party to clear it.

Correction to my previous comment

I wrote that "the codex agent assigned the rebase never pushed" and that the branch "sat unmoved for ~12h." That framing is wrong and I want it corrected in the record.

flows-pr139-rebase-codex-0904 completed the rebase, at 22:59Z — about an hour before I started mine. It committed locally as df7cc1c1 and deliberately did not push, because its brief required my approval before pushing. It then reported and waited. That is exactly the behaviour I asked for. What I observed was an unmoved remote branch, and I read a correct hold as a failure without checking my inbox first.

So the duplicated work is mine, not its.

Its independently-produced result matches mine, which is a useful cross-check on both:

	codex df7cc1c1	mine 8b7148d
kernel	142 passed (114 → 142, +28, 0 removed)	142 passed
SDK	561 passed / 3 skipped (538 → 561, +23, 0 removed)	561 passed / 3 skipped
tsc	3 × exit 0	clean

It also reached the same conclusion on the conflict I hit: server-side error mapping belongs in #137's extracted server/protocol.rs, with #137's canonical surfaces and #139's URI-aware termination gate both preserved.

The one substantive difference is the base: it pinned 27b7151 and, per its rails, did not chase main when 3725025 landed mid-run. Mine is rebased onto 3725025, so the pushed head stands — but it got there first and on the merits.

Its full evidence is at ops/reviews/20260903-pr139-repair-0903.md §14, including a one-sided-file enumeration and a P0 check I did not run: URI ladder with 0 effects and the daemon alive, seven URI attacks live=0, and child-applicator recursion accepted.

It also independently disclosed the intermittent capacity failure — see #155.

VERDICT: PASSED

Independent signoff: PR #139 at 8b7148d

Scope: assessment only. I did not fix product code, push, merge, or resolve review
threads. The review worktree began at exactly
8b7148da9050a14996ecdcd80bb867c2813241c1; its merge-base with the requested
main baseline is exactly 372502560ffcc1de14cb3fe72c852e0490dbfb30.

The rebase preserved both sides of both conflict resolutions and all four
named silent-revert traps. Every semantic claim below has a source mutation,
a changed SHA-256, a failing witness, byte-for-byte restoration, and a passing
witness. The final full gates are 142/142 kernel tests and 561/561 SDK tests
with the expected 3 skips.

Conflict 1: protocol helper relocation plus run_start_error

Textual result

Command:

rg -n 'fn (decode_params|to_value|protocol_conflict|internal_error|error_response|run_start_error)\b' kernel --glob '*.rs' --glob '!target/**'

Literal output:

kernel/relayflowd/src/server/protocol.rs:38:pub(super) fn decode_params<T: DeserializeOwned>(params: Value) -> ProtocolResult<T> {
kernel/relayflowd/src/server/protocol.rs:42:pub(super) fn to_value(value: impl Serialize) -> ProtocolResult<Value> {
kernel/relayflowd/src/server/protocol.rs:46:pub(super) fn protocol_conflict(error: anyhow::Error) -> (&'static str, String) {
kernel/relayflowd/src/server/protocol.rs:65:pub(super) fn run_start_error(error: anyhow::Error) -> (&'static str, String) {
kernel/relayflowd/src/server/protocol.rs:73:pub(super) fn internal_error(error: anyhow::Error) -> (&'static str, String) {
kernel/relayflowd/src/server/protocol.rs:86:pub(super) fn error_response(id: Value, code: &str, message: String) -> Response {

Exact definition counts across kernel/**/*.rs:

decode_params=1
to_value=1
protocol_conflict=1
internal_error=1
error_response=1
run_start_error=1

All six are defined only in server/protocol.rs; none is duplicated in
server.rs. server/protocol.rs imports relayflowd_core::SpecError, and
server.rs calls .map_err(run_start_error) for engine.start.

Clean compiler output, with warnings visible:

There are no unused-import or duplicate-definition warnings.

Mutation: the five upstream-moved helpers remain the live definitions

I renamed all five moved definitions in protocol.rs while leaving their
callers unchanged.

Mutation: SpecError is mapped to invalid_spec, not internal

I changed the SpecError arm in run_start_error from invalid_spec to
internal and temporarily added a direct unit witness. A direct witness is
needed here because handle_request performs an earlier explicit validation;
the contract under review is the error mapper itself.

Silent-revert trap 1: upstream-moved definitions were not dropped

This is covered in two independent ways:

1. The five server helpers have exactly one definition each, all in upstream's
   server/protocol.rs; renaming them caused 48 compiler errors, and restoring
   them produced a warning-free cargo check.
2. The upstream-moved SDK descriptor is byte-identical to main:

$ sha256sum sdk/src/step-fields.ts
3d66671e4af82bf5f9e3940d7c2681882aa0a9f648351985f026763efbe1e8ca  sdk/src/step-fields.ts

3d66671e4af82bf5f9e3940d7c2681882aa0a9f648351985f026763efbe1e8ca  -

The descriptor mutation under trap 3 below also proves its test witness is
live: changing the moved table failed both its exact descriptor assertion and
the validator behavior.

Silent-revert trap 2: compileStep base/per-verb output lowering

Textually, base contains only id, type, dependsOn, and
maxIterations. All three verb branches read the shared
verification = typedOutputVerification(step) binding; the llm and agent
branches pass that lowered value through outputGate.

I reproduced the silent revert by changing the llm and agent branches to
read raw s.verification.

Silent-revert trap 4: trigger lowering survives

compiled.triggers.

The build command exited 0 with no output. Final suite literal summary:

Flakes and reruns

I hit the documented issue #156 ENOENT on both full SDK invocations:

Error: ENOENT: no such file or directory, open '.relayflow/backlog-picker-entry.json'
  path: '.relayflow/backlog-picker-entry.json'

On the first full invocation, the suite also had one transient failure while
still enumerating the expected total:

FAIL tests/live-kernel.test.ts > built flows CLI against live relayflowd > follows a live worker dispatch through flows run
FAILED [protocol_error] relayflowd could not complete the run request: relayflowd returned status parked without a classifiable completion
Test Files  1 failed | 25 passed | 1 skipped (27)
Tests  1 failed | 560 passed | 3 skipped (564)

The exact test immediately passed:

Test Files  1 passed (1)
Tests  1 passed | 26 skipped (27)

It is a reproducible pre-existing default-capacity dispatch race, consistent
with issue #155 rather than a #139 regression. Ten isolated runs at this head
produced FAILURES=4/10. As a control, I created a detached worktree at the
exact main baseline 372502560ffcc1de14cb3fe72c852e0490dbfb30, built the SDK,
and ran the same test ten times; it produced FAILURES=1/10 with the identical
parked/protocol_error signature. No #139 change touches that dispatch path;
the only server.rs diff from main is internal_error to run_start_error on
the engine.start error mapper. The required final full SDK rerun passed all
561 tests.

CI at 1ed9023: two separate problems, one of them new and specific to this branch

Rebased onto the new main (ee28397) so this picks up #154's CI repair. The run then found two things.

1. worker_capacity — not this PR

06:16:41  test worker_capacity::default_capacity_one_reopens_only_after_durable_completion_or_crash ... FAILED

That is #155, pre-existing on main. #158 fixes it (27 runs/4 failures → 60 runs/0 failures). Nothing owed here.

2. A kernel test hangs on the runner — this one looks like ours

06:17:00  test agent::rung_c_sigkill_boundaries_resume_only_unfinished_steps_via_real_cli
            has been running for over 60 seconds
06:42:29  ##[error]The operation was canceled.

Test kernel ran for 30m15s and was cancelled; every later step was skipped, so the SDK suite never ran at all.

Why I think it is this branch and not the runner:

• the same test finishes inside a 38s binary run on feat(sdk): flows tick start — keep a scheduled relayflow firing #157 and feat(surface): add unpublished authored contract foundation #134, whose whole jobs took 4m31s against the same main;
• it passed locally on this exact branch — I ran the full kernel suite at the pre-rebase head and got 142 passed, in normal time;
• the rebase onto ee28397 carried only .github/ changes from main, so nothing in this branch's kernel code moved.

So: environment-sensitive, and only on this branch. This PR reworks gate and termination handling, which is a plausible place for a run that never terminates — rung_c_sigkill exercises kill/resume boundaries against a real CLI, so a resume path that waits on something that never arrives would look exactly like this.

Worth noting it was previously invisible: before #153 the kernel suite never ran in CI at all, so a hanging kernel test cost nothing and showed nothing.

What this needs

Not a rebase and not #158. Someone should reproduce agent::rung_c_sigkill_boundaries_resume_only_unfinished_steps_via_real_cli under runner-like conditions (Linux, cold target, no warm binaries) and find what it waits on. Until then this PR cannot go green even once #158 lands, because the hang is upstream of the SDK step.

The independent signoff at the previous head remains valid for the code — it covered both conflict resolutions and all four traps, with 7 hash-verified mutations. This is a runtime behaviour the signoff's local run did not surface.

[kjgbot]

Correcting my previous comment: the hang is NOT specific to this branch

I said the rung_c_sigkill hang "looks like ours" and gave three reasons. One of them has since been contradicted, so the claim does not stand.

#158 — which is main plus a single-expression kernel change, nothing to do with gates or termination — hangs in the same test, at the same place, for the same duration.

#139  Test kernel 30m15s   agent::rung_c_sigkill_... running >60s   → cancelled
#158  Test kernel 30m16s   agent::rung_c_sigkill_... running >60s   → cancelled

So "only this branch" was wrong. What the four runs actually show:

PR	touches kernel?	rung_c_sigkill
#157 (tick runner)	no	passed, 38s binary
#134 (surface)	no	passed, 38s binary
#139 (gates/termination)	yes	hung, cancelled at 30m
#158 (retry timing)	yes	hung, cancelled at 30m

That is a suggestive split but it is n=2 on each side, and it is equally consistent with a Linux-only flake that the two kernel PRs happened to hit. I have re-run #158's job to tell those apart; if it hangs a second time the split is real, if it passes the hang is a flake and this PR needs no work for it.

Either way the correction stands on its own: do not treat the hang as evidence against this PR's gate/termination changes until the re-run says something. I reached for the most specific explanation available and stated it more confidently than two data points support.

The worker_capacity failure in this PR's run is still #155 and still fixed by #158 — that part is unaffected, and #158's run confirms it on the runner:

test worker_capacity::default_capacity_one_reopens_only_after_durable_completion_or_crash ... ok

Merging: green CI, independent signoff carried, zero unresolved threads

CI green at 4da825b — linux-x64-artifact pass 6m21s.

Getting there took three runs, and the two reds in between were not this PR:

• run 1 — the agent::rung_c_sigkill_... hangs on Linux runners ~half the time, costing 30min and cancelling the job #160 hang, cancelled at 30m14s. That is the ~50% Linux-only kernel hang; I twice wrongly attributed it to this branch's gate work before proving it reproduces on a commit that also passes.
• run 2 — failed 12m49s on live-kernel > follows a live worker dispatch through flows run and cli-hn-monitor > terminates (exit 1) when the worker emits an error asynchronously. Both pass locally on this branch (live-kernel 27/27) and both passed on feat(sdk): flows tick start — keep a scheduled relayflow firing #157's and feat(surface): add unpublished authored contract foundation #134's runs. Catalogued on SDK suite flake: ENOENT '.relayflow/backlog-picker-entry.json' under vitest parallelism #156 as Linux-only flakes.
• run 3 — clean.

I re-ran rather than attributing, which is the rule I wrote up on #156 after getting it wrong twice.

The signoff carries, proven rather than assumed. It returned PASSED at 8b7148d; this head is 4da825b after a rebase onto 4df6d94. Every one of the PR's own non-workflow files hashed at both heads:

PR touches 39 non-workflow files
differing from signed-off head 8b7148d: 0

Only .github/ differs. That signoff was a serious one — 7 mutations, each with before/mutated/restored SHA-256 plus a failing and a passing witness, covering both conflict resolutions and all four known silent-revert traps:

• all six protocol helpers defined exactly once, in server/protocol.rs, none duplicated into server.rs
• run.start maps SpecError → invalid_spec, not internal
• both spec.rs validations (surface identity, JSON Schema) fire
• timeoutMs deterministic-only in both the base spread and the allowlist
• .map(toKernelTrigger) survives
• compileStep's base/per-verb output lowering intact

Zero unresolved review threads.

For the record on the rebase itself: the conflict was trap 1 — main had moved five protocol helpers out of server.rs into server/protocol.rs, and this branch re-added all five. Taking "both sides" would have silently duplicated them. I verified each function's definition count against main before resolving, kept main's, and relocated only run_start_error — the one genuinely new. The signoff independently re-derived the same conclusion.
