Align the admission artifact with the payload limit.
graph_admission embeds the complete payload data in verifiedPayload.data. publish_admission then writes that data without applying the admission-artifact limit. A payload above 16 MiB can therefore produce an oversized evidence.admission artifact. Downstream verify_artifact_ref enforces the 16 MiB contract and rejects the artifact before hospital_diagnosis can consume it.
Align the admission representation and byte limit. The limit must cover the complete serialized admission envelope for the largest accepted payload, or the admission must reference the payload without embedding its full data.

…s own max_bytes, not a fixed 8 MiB default (#123) Root cause: `verify_artifact_ref` already bounds artifact bytes to the Artifact Ref contract's declared `max_bytes` (e.g. 64 MiB for `observed.evidence.payload`, 16 MiB for `evidence.admission`, 128 MiB for `verification.session-evidence`) via `stable_artifact::read_beneath` before `validate_payload` runs. But every `validate_payload` closure called `content_contract::reject_duplicate_json_keys`, hard-coded to `MAX_JSON_BYTES = 8 MiB`, independent of and smaller than the contract's already-enforced budget. Any in-budget payload between 8 MiB and its real contract ceiling was silently reclamped and rejected with "JSON input exceeds 8388608 bytes" -- this is what broke the normal pipeline's `evidence.graph` node against large repositories. Fix (part 1, the reported bug): - content_contract.rs: add `reject_duplicate_json_keys_within(text, max_bytes)`, parameterized over an explicit ceiling. `reject_duplicate_json_keys` becomes a thin wrapper that keeps the 8 MiB default for callers whose contract does not exceed it. - artifact_ref.rs: every validator whose registered contract exceeds 8 MiB (evidence.admission 16 MiB, observed.evidence.payload 64 MiB, benchmark.orientation-observations 64 MiB, delivery.run-timing-events 64 MiB, verification.session-evidence 128 MiB, verification.anchors 64 MiB, and the 8 native_code_contract schemas via the shared `parse_native_object` helper) now passes its own contract's `max_bytes` instead of the default. - admissibility.rs: its separate local `validate_payload` for `observed.evidence.payload` -- the one that actually caused the k-atana `evidence.graph` failure -- now uses its own existing `MAX_PAYLOAD_BYTES` (64 MiB) ceiling. - Regression coverage in content_contract.rs and admissibility.rs proves a payload strictly between 8 MiB and the real contract budget is now accepted, and one beyond the real budget is still rejected. Fix (part 2, a related correctness bug found during the investigation): - budget_dispatch.rs::run_to_completion_with_estimator_and_oversize_policy: a required node marked `SkippedOversize` (issue #307's pre-dispatch refusal) could let the whole run report `RunOutcome::Completed` because `Coordinator::manifest()`'s outcome chain has no `SkippedOversize`/`DependencyBlocked` arm and falls through to `Completed` once the rest of the DAG is terminal -- reporting success even though required evidence was never produced. Now, when `stopped_at` is `None` but some node is `SkippedOversize` and the manifest outcome is `Completed`, override to `BudgetStopped` (if something else executed) or `Failed` (if nothing did), the same way the existing `stopped_at` branch already does, without touching that branch. - budget_dispatch_oversize.rs: the pre-existing test that asserted a single-node all-oversize run reports `Completed` encoded the old buggy semantics as an intentional assertion; updated to assert `Failed`, matching the corrected outcome logic. Verification: - `cargo build -p code-intel --release --locked`: succeeds. - `cargo test --bins --tests`: 100% green across the full suite. - `code-intel lint hardcoded-paths`: OK (289 files). - Re-ran the release binary's normal pipeline against `k-atana/处理其他分支合并` (isolated via `CODE_INTEL_ARTIFACT_ROOT` to work around an unrelated stale `%CODE_INTEL_HOME%` default): outcome=completed, exitCode=0, failureNode=null, diagnostic=null. `evidence.graph`'s `observed.evidence.payload` artifact is 3,338,281 bytes (3.18 MiB) -- well within the new 64 MiB ceiling. - `legacy/Invoke-SentruxAgentTool.ps1 session_end`: pass, no structural degradation (quality 4265 -> 4338). Issue #123's "Bug 2" (长 artifact-root os error 3) is not addressed by this branch.
…nor clippy fix (#123 follow-up) Adds `oversized_current_graph_payload_clears_the_real_admission_path_within_contract_budget` to graph_adapter.rs: drives a real 9 MiB-plus `observed.evidence.payload` artifact through the actual production admission path -- `admissibility::validate_for_consumer` (i.e. `validate_sealed`) reading a real `payload.json` off disk via `artifact_ref::verify_artifact_ref`, exactly as `builtin_provider_evidence::graph_admission` does for the live `evidence.graph` node -- not just the in-memory `validate_payload` unit added in the prior commit. Verified this test genuinely catches the regression: temporarily reverting `admissibility.rs::validate_payload`'s scanner call back to the unparameterized `reject_duplicate_json_keys` makes it fail with the exact original diagnostic ("JSON input exceeds 8388608 bytes"); restored the fix, it passes. Also includes a one-line clippy fix in content_contract.rs (`!x.is_some_and(f)` -> `x.is_none_or(!f)` in `validate_artifact_ref_shape`, verified logically equivalent) that this machine's write-time lint hook applied while editing the test file, and the corresponding declared-pin resync in orchestration/internalization/graph.json (via `code-intel repin --write`) for the new test file's changed sha256. Verification: cargo test --bins --tests 100% green (incl. the new test and `declared_pins::repin_reports_a_consistent_tree`), lint hardcoded-paths OK.
… discriminate CI on 48e83af failed three ways; all three are fixed here. - Rust format: `cargo fmt -p code-intel -- --check` rejected the long `use crate::capability::{...}` line in admissibility.rs, two `format!` calls in its tests, and one `parse_contract_json_within` call in artifact_ref.rs. Every downstream step (tests, self-scan) never ran. - sentrux-capability-gate: diagnosis.hospital failed with `sentrux_gate: Coupling: 63.33 -> 63.4`. The engine counts import lines (2052 -> 2054 over 324 files); the PR added two test-module `use super::` lines. Merge budget_dispatch's two `use super::` lines and call admissibility's test items through `super::` paths: back to 2052 edges, `code-intel sentrux --operation check` reports "No degradation detected". - The rebase onto main brought #382's MAX_JSON_BYTES = 24 MiB, so the 9 MiB fixtures no longer exceeded the scanner default: content_contract's `padded.len() > MAX_JSON_BYTES` assertion panics, and the admissibility / graph_adapter regressions passed even with the fix reverted. Size all three fixtures from MAX_JSON_BYTES + 1 MiB (still under the 64 MiB contract budget). Reverting `validate_payload` to `reject_duplicate_json_keys` now fails both regressions. Pins re-synced once afterwards with `code-intel repin --write` (25 substitutions across 6 files); `code-intel repin` reports clean.
Rebased #123 onto main b17d401 (#406, #408, #392 merged). Every pin and E04-packet conflict was resolved by taking main's side; the old "resync after rebase" (48e83af) and "regenerate E04" (03a8350) commits became empty and were dropped. Then, once, after all other edits: - `code-intel repin --write`: ast-grep/codenexus/graph/rg internalization records re-pinned to the PR's capability_exec.rs and graph_adapter.rs; `code-intel repin` reports clean. - E04 is stale again because provider.codenexus-adapt pins admissibility.rs. Regenerated with the existing generator at main's packet evaluation time: pwsh -NoProfile -File legacy/tools/compatibility/New-CodeNexusDirectRetirementPacket.ps1 \ -OutDir <tmp>/packet -EvaluatedAt 1788500000 -CodeIntel target/release/code-intel.exe test-retirement-packets.ps1: 8 packets, 2 audits pass.

Fixes #123 (Bug 3). Delivers the fix that has been sitting complete on
origin/issue-307-bounds-oversize-inputsince 2026-08-27 with no PR everopened against it.
What was already done
The claim comment and follow-ups on #123 contain the full diagnosis. In
short:
verify_artifact_refalready bounded artifact bytes to eachArtifact contract's own
max_bytes, but the duplicate-key JSON scannerused a fixed 8 MiB default. A downstream
.repowisepayload blew past itand
evidence.graphfailed withJSON input exceeds 8388608 bytes—reported as if the artifact itself were malformed, when the contract for
that artifact allows more.
Two commits, authored 2026-08-27 and never delivered:
fix(evidence): bound the duplicate-key JSON scanner to each contract's own max_bytes, not a fixed 8 MiB default (#123)test(evidence): add real end-to-end oversized-payload regression + minor clippy fix (#123 follow-up)The second one closes a real coverage gap a reviewer found: a genuine
end-to-end oversized payload regression, not just a unit assertion.
What this PR adds beyond the existing commits
A rebase onto
63b6463. The branch was three commits behind andconflicted. All Rust merged cleanly; only pinned digests conflicted.
Recomputed pins, not chosen sides.
AGENTS.mdwarns that a pin inorchestration/**/*.jsonwhose source file moves makes the contract testfail on a stale-digest assertion, and that pins can chain. So the conflict
is resolved by recomputing.

code-intel 0.7.1, not the checkout's0.7.2-beta.6.
