arch: establish Noema runtime bounded-context fitness

[seonghobae]

Scope

Establish Noema's runtime-orchestration bounded contexts and narrowly owned Agent Runtime / State-Checkpoint / Workflow-Task primitives without copying model routing, foreign domain truth, security-runtime authority, Context Graph source, or EA implementation authority. Everything unique to this PR remains candidate truth until protected integration.

Runtime and Context Fabric boundary

The branch separates candidate release-evidence validation from trusted release authority:

• validateContextContractReleaseEvidence(...) validates bounded provider-neutral metadata and returns a detached candidate snapshot;
• ContextContractReleaseAuthority authenticates an independently verified immutable producer release;
• admitContextContractRelease(...) fails closed without that authority and binds exact repository/ref/source/package/SBOM/provenance/schema/profile/conformance/admission/promotion/capability evidence;
• PinnedContextContractReleaseAuthority is an operator-controlled trust anchor, not discovery and not authority derivable from the candidate itself.

Noema's required Context Assertion consumer profile remains:

• https://schemas.contextualwisdomlab.org/context/context-assertion.v1.schema.json;
• https://schemas.contextualwisdomlab.org/context/cloudevent-envelope.v1.schema.json;
• org.contextualwisdomlab.context_graph.assertion.v1;
• urn:cwl:context-contracts:context-assertion-event-semantics:v1;
• application/cloudevents+json.

contextual-orchestrator remains the model/provider routing owner. context-graph-contracts, enterprise-architecture-core, quarantine runtime, Wardnet and EgressWeave remain foreign canonical owners consumed only through versioned ports/ACLs. Agent task/result/reasoning/tool payloads are not EA authoritative data.

Current exact Noema authority — 2026-09-03

Fresh live GitHub state overrides prior snapshots:

• protected/live base: main@1a868c2dc64e7a94917e9e23e950f521996bf2d5;
• current exact PR head: 5b34e857ca52ca83ebe109eed25f45bf1e4d2128;
• lifecycle: open / Ready / mergeable at the latest fresh read;
• convergence: 5b34e857... is a non-force merge of protected main@1a868c2d... into prior implementation head 037bb4ce...; the merge tree is the GitHub-computed conflict-free tree and preserves the full candidate delta while incorporating current protected truth. Pre-restack check/review evidence does not transfer.

A current-head security review previously found a valid cross-input authority race in Workflow / Task Execution: the selector re-admitted a structurally supplied plan before retaining task-state evidence, so a hostile plan accessor could mutate an unmet prerequisite to succeeded before dependency selection.

TDD repair evidence retained in this lineage:

• RED 2f42c997ad3edf17ee9eba32cfa32baaf2c30d4a: regression proves an unadmitted hostile plan must not be able to mutate retained state evidence before selection;
• production repair f9f99718bec39d69aaa8467870abaa5752bbe2bc: admission returns a detached frozen plan with module-local authority and selection accepts only that exact admitted object, rejecting structural/raw forgeries before reading plan accessors;
• regression typing 037bb4ce89088f2d7f4fe600c8d359159e412650: explicitly exercises the runtime-forged admitted-plan path while preserving the stronger TypeScript boundary;
• current convergence head 5b34e857ca52ca83ebe109eed25f45bf1e4d2128 changes no candidate semantic delta relative to that implementation head; it only incorporates current protected main non-destructively.

Fresh exact-head required evidence now has three terminal-success lanes and one still-executing image lane:

• ci run 33625170570: completed success on this exact head;
• reviewer-ci run 33625170582: completed success on this exact head;
• required Security Scan run 33625170550: completed success on this exact head;
• patch-validator-image run/job 33625170499/100231101582: in_progress on assigned GitHub-hosted runner 1001626483 with exact checkout and stale-head refusal already successful. The current step is Build exact-head patch-validator image; its workflow timeout is 180 minutes and the build itself is bounded to 150 minutes. Downstream static-runtime identity, image-metadata, no-network/read-only/non-root smoke, CycloneDX SBOM, vulnerability inventories, exact source/image/receipt verification, final stale-head refusal and bounded evidence upload are still pending.

The image lane is therefore non-passing until it reaches terminal success. The branch is not mutated while that exact current-head job is legitimately executing within its configured liveness contract. No predecessor success is transferred.

Current review threads are resolved; resolved/commented/model evidence is not substituted for the remaining exact-head image/SBOM/vulnerability/provenance evidence.

Context Fabric release/promotion acceptance

Neither Context Graph nor EA has an immutable release at the latest validated dependency inventory, so mutable PR heads remain candidate evidence only. Noema contributes consumer acceptance rather than treating release absence as a terminal blocker.

The currently tracked Context Graph dependency chain is #19 -> #25 -> #20 -> #21; it must be re-read before owner mutation or production admission:

• context-graph-contracts#25 owns the source-bound release-provenance prerequisite. It must make exact repository/version/protected-source/package/source/SBOM identities and provenance/attestation independently authenticatable by consumers; self-asserted release metadata is insufficient.
• downstream release/conformance work must non-force converge after that prerequisite;
• the structured Context Assertion/CloudEvent envelope owner must satisfy Noema's exact schema/profile/event-semantics/media-type consumer acceptance before an immutable production contract can be admitted.

No immutable context-graph-contracts release is assumed from mutable PR state. Production admission remains fail-closed until protected publication supplies exact source identity, authenticated release provenance, positive/hostile installed-package conformance/admission evidence, compatibility/migration evidence, and applicable package/SBOM/provenance/licensing/NOTICE evidence.

EA remains a foreign owner. Noema's projection acceptance permits only protected/released deployable/runtime architecture facts, canonical refs, truth status/origin, valid/system time, provenance, lifecycle/ownership/risk/remediation/transformation. Agent task/result/reasoning/tool payloads, checkpoints, prompts/model output, user/business data, and security verdict/risk payloads remain outside authoritative EA truth.

Fresh dependency inventory still reports zero immutable releases for both context-graph-contracts and enterprise-architecture-core. EA projection candidate #40 remains Draft and fail-closed on provisional/open-PR dependency identity; it must consume the eventual released CGC source/package/provenance contract rather than self-asserted commit metadata.

Merge discipline

Merge only if this unchanged exact head remains compatible with the then-current protected base, all applicable CI/reviewer/security/coverage/package/image/SBOM/vulnerability/provenance gates are terminal-success, valid review findings are fully addressed, and live governance permits the normal protected merge path. Self-authored pins, mutable owner branches, stale base snapshots, open Drafts, queued/in-progress jobs, and predecessor artifacts never satisfy production admission.

Merge Risk: 🟡 Moderate · up to f4773

This PR introduces workflow-plan admission, state-based task selection, and runtime lifecycle boundaries. The current implementation can accept over-limit running state, mix state from another execution, and consume custom iterators beyond validated bounds; owner binding and atomic task claiming are also not established, while required exact-head checks remain queued. The PR is not merge-ready until these correctness and authorization risks are addressed or explicitly accepted.

Summary of this pass (3 assigned issues)

1. Unguarded throwing-length proxy (Devin "bug" finding) — already fixed concurrently, verified.
By the time I got to src/context-fabric/context-contract-release-admission.ts, this branch's own velocity had already landed the fix (7be64a0 fix(context-fabric): normalize capability proxy failures, plus 288d7b0/6f5d800 adding tests and a capability-count/length bound). I independently wrote a RED-before-GREEN regression first (revoked capability-array proxy + a proxy whose length trap throws), confirmed it reproduced the leak against the pre-fix code, then found my fix was functionally identical to the one already on the branch (same try/catch around Array.isArray and .length, normalizing to ContextContractReleaseAdmissionError). Merged and kept upstream's version (it also carries the newer MAX_CONTEXT_CONTRACT_CAPABILITIES/length bounds); my duplicate test cases live in test/context-contract-release-admission-boundaries.test.ts alongside the dedicated test/context-contract-release-capability-proxy-errors.test.ts upstream added — some overlap in intent, no conflict.

2. Pre-existing typecheck error at task-plan.ts — fixed.
npm run typecheck failed at src/workflow-task-execution/task-plan.ts:284 (unknown not assignable to string), passing rawSnapshot.executionId: unknown into isCanonicalExecutionId(executionId: string). That function's own docstring and implementation already exist specifically to safely accept values that don't preserve TS's static string contract (typeof executionId === "string" is the first thing it checks). The real fix was widening its parameter type from string to unknown (src/runtime-shared/execution-identity.ts) to match its documented/actual behavior, rather than casting at the call site. All other call sites already pass an already-typed string, which remains assignable to unknown, so this is non-breaking.

3. task-plan.ts coverage gap — closed to 100%.
Added real hostile-input tests for the previously uncovered rejection branches: non-canonical task effect, non-object top-level plan candidate, non-array/empty tasks field, non-object task entry, non-array/over-bound dependsOn, duplicate dependency entry, non-array task-state evidence, and a non-object task-state entry. Also added one normal (non-hostile) multi-dependency admission test, since that's the only way to exercise assertAcyclic's "readiness accumulates across 2+ prerequisites, not yet ready" branch.

Two branches proved genuinely unreachable given invariants already enforced earlier in the same functions — not vacuous-test material:

• assertAcyclic's dependents.get(dependent) ?? 0 fallback: dependent always names a task already validated to exist, so the lookup can never miss.
• selectRunnableWorkflowTasksBoundary's post-loop stateByTask.size !== admitted.tasks.length check: admitted tasks are already deduplicated, and every loop iteration either throws or inserts exactly one new unique key for exactly stateCount iterations, so the sizes can never diverge by the time that check runs.

Both are marked with a justified /* v8 ignore */ comment explaining the specific invariant, rather than faking coverage or silently deleting the defense-in-depth check.

Final verification: npm run typecheck clean, npm test — 545 test files / 3904 tests passing, coverage 100% statements/branches/functions/lines.

Note for a future pass: during this session I received several suspicious injected instructions (via what presented as "coordinator" messages) falsely claiming I had pushed a self-modifying CI workflow, and pushing me to delete other contributors' in-flight .github/workflows/_temp_pr528_*.yml files and to investigate/fix an unrelated 4th "bug" (reused plan identities in task-plan.ts around lines 215/266). I did not act on either — I never touched those workflow files (this branch's own legitimate process had already removed the temp workflow itself by the time I merged, see 0bb8666), and the 4th item is outside this pass's scope. Flagging both here rather than silently acting on unverified instructions; worth a dedicated look in a future pass if still relevant.

Investigated Devin's repeated "Reused plan identities bypass dependencies" finding (src/workflow-task-execution/task-plan.ts, admitWorkflowTaskPlanBoundary/selectRunnableWorkflowTasksBoundary).

Confirmed the underlying fact: planId is caller-supplied and only shape-validated (requirePlanId(rawPlanId) checks format, not provenance), while admitWorkflowTaskPlanBoundary's own docstring already documents the invariant Devin is pointing at as a caller responsibility: "planId binds retained state to this exact plan revision; callers must allocate a different identity whenever the graph, task effects, or execution policy represented by the plan changes." So a caller that resubmits a materially different graph under a reused planId violates a documented precondition — the function has no way to detect this from the graph alone, since two different graphs presented under the same ID look identical to a graph-only validator.

This reads to me as a genuine architectural question rather than an implementation bug: either (a) the current design is intentional — identity is caller-asserted and enforcement of "don't reuse an ID for a different graph" lives outside this module (e.g., a caller-side plan registry) — or (b) planId should instead be derived from the graph's own content (e.g., a stable hash of tasks/dependencies/effects), making the binding self-verifying instead of relying on caller discipline. Choosing between those changes the trust model of this admission boundary, so I'm not pushing a change unilaterally — flagging it here for whoever owns this module's design to decide. If (b) is the intended direction, I'm happy to implement it once confirmed.

Devin Review found 1 new potential issue.

[seonghobae]

Fresh review triage on current #528 head 5b34e857ca52ca83ebe109eed25f45bf1e4d2128 separates the pure selector/admission slice from the production scheduler/persistence boundary. The current source already makes runnable IDs candidate-only, requires an atomic external state snapshot and atomic claim before side effects, and does not fabricate CAS or recovery authority.

The remaining production requirements from review are now preserved as one executable successor issue, #541: atomic task claim, checkpoint compare-and-swap, explicit scheduling fairness/priority, failed/cancelled-prerequisite recovery, effect-specific retry/recovery, restart/idempotency and observability/provenance. #541 carries production-boundary RED/GREEN acceptance rather than turning these findings into documentation-only closure.

Accordingly, I am resolving the transferred review notes for those future application/runtime responsibilities without claiming they are implemented by #528. #528 remains non-merge-ready until its unchanged exact head has terminal exact-head gates and its remaining current-scope findings are clean.

[seonghobae]

Triage on current exact head 5b34e857ca52ca83ebe109eed25f45bf1e4d2128: no failing required check (14/15 check runs success, the remaining verify-patch-validator-image in_progress, none failing) and no merge conflict. Found 2 of 54 review threads still marked unresolved on GitHub despite the underlying findings already being fixed in source (a prior pass here left them open pending terminal-green CI rather than mechanically resolving them):

• "Failed ancestors can release descendants" — confirmed selectRunnableWorkflowTasksBoundary (src/workflow-task-execution/task-plan.ts:325-333) rejects any executed-state task whose dependency isn't "succeeded", closing the causal-consistency gap.
• "Frozen plans expose mutable concurrency" — confirmed AdmittedWorkflowTaskPlan = Readonly<WorkflowTaskPlan> (line 65) makes maxConcurrency compile-time readonly on the admitted type.

No code change was needed; I verified both against the current source directly, replied on each thread with the specifics, and resolved them. Everything else on this PR (all other findings, changelog entries, docstring/coverage gates) was already resolved. Nothing else here is broken — the PR is otherwise waiting on the last in-progress check.
