From 044cb930832e2b1a088ab21d91e16fc0deb5dcd9 Mon Sep 17 00:00:00 2001 From: DavidHLP Date: Mon, 28 Sep 2026 15:16:38 +0800 Subject: [PATCH 01/34] feat: let an analysis cite from an explicitly versioned corpus analyze_submission read the pinned sample corpus directly, so how many citations an answer could emit was fixed by that corpus: a status-filtered retrieval keeps only fragments carrying the submission status, and the pinned corpus holds exactly one such fragment. The acceptance asks for three. The corpus is now an optional parameter that defaults to the pinned one, so the recorded evaluation baseline is untouched, and the three-citation behaviour is covered on a separately versioned fixture of three self-authored status-bearing sources: three distinct citations, all passing the integrity gate. --- services/agent/src/sourced_analysis.py | 17 +++++-- services/agent/tests/test_sourced_analysis.py | 48 +++++++++++++++++++ 2 files changed, 62 insertions(+), 3 deletions(-) diff --git a/services/agent/src/sourced_analysis.py b/services/agent/src/sourced_analysis.py index 158882d017..a77a4b3d8a 100644 --- a/services/agent/src/sourced_analysis.py +++ b/services/agent/src/sourced_analysis.py @@ -6,7 +6,7 @@ import unicodedata from citation_integrity import check_citations -from retrieval import keyword_search, load_sample_corpus +from retrieval import SourceDocument, keyword_search, load_sample_corpus _ALLOWED_STATUSES = { @@ -58,19 +58,30 @@ def validate_submission_facts(submission: dict[str, object]) -> tuple[str, str]: return submission_id, status -def analyze_submission(submission: dict[str, object], question: str) -> dict[str, object]: +def analyze_submission( + submission: dict[str, object], + question: str, + *, + documents: tuple[SourceDocument, ...] | None = None, +) -> dict[str, object]: """Return facts, hypotheses, citations, and per-citation integrity checks. ``citation_checks`` records whether each citation is traceable to its source document.

A supplied corpus was accepted as-is: check_citations compares each citation against the same caller-provided objects, so a document claiming a licensed scope or a nonexistent source path could reach the model marked verified. The seam now requires the corpus to arrive with its own manifest, passes it through assert_manifest_covers (content digests and declared fields bound to the exact text), and refuses anything not declaring itself agent-authored synthetic — a test seam may exercise the evidence path but may not launder a document into real or licensed material. The status filter ran after keyword_search had already ranked and truncated to MAX_RESULTS, so higher-ranked documents without the status could consume every slot and a status-bearing document that answered the question was dropped. keyword_search takes an optional require_text that narrows the corpus before ranking and before the limit; analyze_submission passes the normalized status, which is the same set the old post-filter selected, now ordered correctly.

charset=UTF-8 Content-Transfer-Encoding: 8bit The three-citation behaviour only existed in a unit test: the DAV-45 entry point called analyze_submission with no corpus, so it always used the pinned corpus, which holds one status-bearing document, and always stopped at insufficient_citations. The analysis core is now shared by two callers with different material policies: - analyze_submission keeps its synthetic-only rule — it is the test seam, and a fixture may exercise the evidence path but never present itself as real material. - analyze_authorized_submission is the acceptance path: the caller pins the permission and scope it accepts, and every manifest entry must declare exactly those, after the same parse, content binding and source-cap checks. The corpus cannot grant itself a policy; authorised material flows because the run pinned it, not because a file said so. The entry point takes ULTICODE_CITATION_CORPUS_DIR plus ULTICODE_CITATION_CORPUS_MANIFEST — both or neither, resolved before the first request — loads declarations from the manifest, refuses a symlinked or missing entry, a declaration outside the pinned policy, and a file over the source cap, and hands the same corpus and manifest to the worksheet. The default with neither variable set is the pinned, manifest-gated loader, unchanged. Tests: partial configuration refused, a declared-but-missing file refused, an unsupported declaration refused before any call, the override corpus actually being analysed (three rows judged, no material-gap failure), authorised material accepted under a pinned policy, a policy mismatch refused, and the unit seam still refusing authorised material. --- services/agent/e2e_citation_support_model.py | 108 ++++++++++++- services/agent/src/sourced_analysis.py | 147 ++++++++++++------ .../tests/test_e2e_citation_support_model.py | 139 ++++++++++++++++- services/agent/tests/test_sourced_analysis.py | 98 +++++++++++- 4 files changed, 436 insertions(+), 56 deletions(-) diff --git a/services/agent/e2e_citation_support_model.py b/services/agent/e2e_citation_support_model.py index c4d5488701..d943bdfdfa 100644 --- a/services/agent/e2e_citation_support_model.py +++ b/services/agent/e2e_citation_support_model.py @@ -37,8 +37,8 @@ _reject_duplicate_keys, model_label, ) -from retrieval import load_sample_corpus -from sourced_analysis import analyze_submission, first_wrong_answer_submission +from retrieval import MAX_SOURCE_CHARS, SourceDocument, load_sample_corpus +from sourced_analysis import analyze_submission, analyze_authorized_submission, first_wrong_answer_submission from ulticode_client import UlticodeClient from ulticode_tools import build_tools @@ -211,12 +211,98 @@ def _claim_verdict_file(path: Path) -> Path: return lock + + +#: Optional override: point this run at a corpus outside the repository without +#: editing it.

P1 duplicate physical sources: two manifest entries with distinct ids could resolve to one file, so a single fragment counted as several citations and the three-citation gate could pass on a repeat. Resolved paths are now tracked and a second entry over the same file is refused. P1 documentation: the two operator-facing variables, their both-or-neither rule, the manifest policy pin and the layout rules are now written up in services/agent/README.md with the full reason list, and invoked in docs/DEVELOPMENT.md next to the rest of the citation-support runbook. Provenance label: the metadata and evidence line hardcoded `agent-authored-synthetic`, so an authorised corpus would have been recorded as synthetic. Both now carry the pinned permission the run validated. Source position: derived from the loaded text instead of copied from the manifest, and a declared position that does not match the file is refused — a one-line document declaring `lines 900-999` can no longer travel into a citation as a verified location. Malformed manifests: load_manifest failures (missing, unreadable, invalid JSON, validation) are normalized to `corpus_manifest_unusable`, so the smoke emits its evidence line instead of a traceback. Test seam: the synthetic rule now covers the manifest permission as well as the document fields, since load_manifest accepts a synthetic document carrying a licensed permission. Five regressions, each red first (duplicate source fails with error=ManifestError before the fix, position mismatch and the label pass the run they must refuse, the malformed manifest raises instead of printing its reason, the seam admits the licensed permission).

Hard links: two names for one inode produce different resolved paths, so distinct ids over one physical file slipped past the duplicate check and could satisfy the three-citation gate on a repeat. Identity is now the filesystem's — (st_dev, st_ino). Line offsets: the range was derived from the stripped text, so leading blank lines disappeared and content starting on line 3 claimed `lines 1-N`. It now spans the first to last non-blank physical line of the raw file. Read failures: an entry that is unreadable or not UTF-8 raised OSError/UnicodeError instead of the documented reason; both now normalise to corpus_entry_unusable. Gap label: the insufficient_citations line hardcoded the synthetic label while the success line used the selected one, so a gap under an authorised policy blamed the wrong corpus. Synthetic scope: the seam pinned the permission but not the scope, and the worksheet publishes scope as permission_scope — a fixture could declare licensed material there. The seam now requires the exact checked-in synthetic scope value verbatim; a substring test would accept arbitrary text that happens to contain the phrase. Empty manifest: `[]` was normalised into corpus_manifest_unusable, making the documented corpus_empty unreachable; it is classified before validation now. --- services/agent/e2e_citation_support_model.py | 56 +++++++++--- services/agent/src/sourced_analysis.py | 11 +++ .../tests/test_e2e_citation_support_model.py | 86 ++++++++++++++++++- services/agent/tests/test_sourced_analysis.py | 16 ++++ 4 files changed, 154 insertions(+), 15 deletions(-) diff --git a/services/agent/e2e_citation_support_model.py b/services/agent/e2e_citation_support_model.py index aa15fe8d12..c7aedf110b 100644 --- a/services/agent/e2e_citation_support_model.py +++ b/services/agent/e2e_citation_support_model.py @@ -266,7 +266,7 @@ def _claim_verdict_file(path: Path) -> Path: #: a reviewed edit, not something a corpus file can talk its way into.

Authorised material From 4ad4034491baf08a231433776abe955fb898402f Mon Sep 17 00:00:00 2001 From: DavidHLP Date: Mon, 28 Sep 2026 17:16:28 +0800 Subject: [PATCH 12/34] fix: reject copied fragments and read entries through one no-follow descriptor Two findings on the merge commit. Byte-for-byte copies under separate filenames have separate inodes, so the identity check let one fragment be counted three times through `copy.md` next to `status-1.md`. Loaded text is now digested as it is read and a repeated digest is refused with corpus_entry_duplicate_content. The entry was checked with is_symlink/stat and then read by a separate open, so a path swapped for a symlink in between was followed. The read now happens once, on an O_NOFOLLOW descriptor, with type and identity taken from fstat of the bytes actually read; a link is refused by the kernel as corpus_entry_escapes_root. Regressions, both red first: three byte-identical sources (accepted before, refused now) and a symlinked entry whose path check is blind to links (the old code followed it and failed later on position, the new code refuses at open and leaves the target untouched). Docs name both reasons and the single no-follow open. --- docs/DEVELOPMENT.md | 2 +- services/agent/README.md | 9 ++-- services/agent/e2e_citation_support_model.py | 44 +++++++++++++++---- .../tests/test_e2e_citation_support_model.py | 40 +++++++++++++++++ 4 files changed, 82 insertions(+), 13 deletions(-) diff --git a/docs/DEVELOPMENT.md b/docs/DEVELOPMENT.md index 7a6d13473a..c592630e4d 100644 --- a/docs/DEVELOPMENT.md +++ b/docs/DEVELOPMENT.md @@ -105,7 +105,7 @@ ULTICODE_CITATION_CORPUS_MANIFEST=/绝对路径/manifest.json \ uv run python e2e_citation_support_model.py ``` -声明一律以 manifest 为准（缺失/不可读/非法 JSON/校验不过 → `corpus_manifest_unusable`），每条必须逐字等于源码里钉死的 `ACCEPTED_PERMISSION` 与 `ACCEPTED_SCOPE`（`corpus_declaration_unsupported`）；根目录必须是真实目录而非符号链接（`corpus_root_unusable`），manifest 至少声明一条（`corpus_empty`）；目录内按 manifest 自身 `source_path` 的文件名解析，一条对应一个文件，符号链接（`corpus_entry_escapes_root`）、缺失（`corpus_entry_missing`）、两个条目指向同一个**文件**（含同一 inode 的两个硬链接名，`corpus_entry_duplicate_source`，单片段不得被计成多条引用）、不可读/非 UTF-8/为空/超 `MAX_SOURCE_CHARS`（`corpus_entry_unusable`）都直接失败；空 manifest 列表单列为 `corpus_empty`（区别于解析不了的 `corpus_manifest_unusable`）；`source_position` 由**原始文件**推导（首末非空物理行，前导空行也计入），与 manifest 不符即 `corpus_entry_position_mismatch`。不设这两个变量时行为与默认完全一致。证据行与 verdict 元数据里的 `corpus=` 取自钉死的 permission，因此非 synthetic 材料不会被标成 synthetic。契约细节见 `services/agent/README.md`。 +声明一律以 manifest 为准（缺失/不可读/非法 JSON/校验不过 → `corpus_manifest_unusable`），每条必须逐字等于源码里钉死的 `ACCEPTED_PERMISSION` 与 `ACCEPTED_SCOPE`（`corpus_declaration_unsupported`）；根目录必须是真实目录而非符号链接（`corpus_root_unusable`），manifest 至少声明一条（`corpus_empty`）；目录内按 manifest 自身 `source_path` 的文件名解析，一条对应一个文件，符号链接（`corpus_entry_escapes_root`）、缺失（`corpus_entry_missing`）、两个条目指向同一个**文件**（含同一 inode 的两个硬链接名，`corpus_entry_duplicate_source`；逐字节相同的副本 `corpus_entry_duplicate_content`；条目用 `O_NOFOLLOW` 单次打开，检查与读取之间被换成符号链接也由内核拒绝——总之单片段不得被计成多条引用）、不可读/非 UTF-8/为空/超 `MAX_SOURCE_CHARS`（`corpus_entry_unusable`）都直接失败；空 manifest 列表单列为 `corpus_empty`（区别于解析不了的 `corpus_manifest_unusable`）；`source_position` 由**原始文件**推导（首末非空物理行，前导空行也计入），与 manifest 不符即 `corpus_entry_position_mismatch`。不设这两个变量时行为与默认完全一致。证据行与 verdict 元数据里的 `corpus=` 取自钉死的 permission，因此非 synthetic 材料不会被标成 synthetic。契约细节见 `services/agent/README.md`。 少于 `ULTICODE_CITATION_REQUIRED_ROWS`（默认 3）报 `insufficient_citations`；未过**完整性门禁**的引用在**发起任何模型调用之前**就报 `citation_integrity_failed`；verdict 汇总阶段发现不支持的引用报 `citation_gate_failed`。这些都以至退出码 1 结束，不报「低分通过」。输出行标注 `judge=model` 与 `human_review=not_performed`，以便与将来的人工复核记录区分。verdict 默认写到**状态目录**（`$XDG_STATE_HOME` 为绝对路径时用它，否则 `~/.local/state`）下的 `ulticode/citation-verdicts-<随机>.json`：每次运行独立，且不落在 checkout 里，可用 `ULTICODE_CITATION_VERDICTS` 改路径；无论哪种，目标位置都会在**付费调用之前**被独占占位，不可写或已被占用即 `verdict_destination_unusable`；写盘同时生成 `.meta.json` 附属文件，记录判定者（`judge=model`）、模型标签、语料、阈值与提交事实摘要，使 verdict 脱离本次会话仍可解释。密钥只从环境读取，不得写入日志或仓库；上面两条真实模型入口示例中的 `DEEPSEEK_API_KEY=...` 只是占位符，实际运行同样应先在环境中导出。 diff --git a/services/agent/README.md b/services/agent/README.md index 897e2cf3d9..9c0bc92049 100644 --- a/services/agent/README.md +++ b/services/agent/README.md @@ -89,10 +89,13 @@ Contract — every violation is a fixed `FAIL reason=...` evidence line and exit manifest → `corpus_manifest_unusable`.

Anchored reads: O_NOFOLLOW only guards the final component, so a corpus directory replaced by a symlink after the root check was still followed. The root is now opened once with O_DIRECTORY|O_NOFOLLOW and every entry with dir_fd, fstat identity taken from the descriptor actually read, and ownership transferred to fdopen before the read so a failed read is reported once instead of EBADF masking it. Bounded reads must reach EOF: a 1200-character prefix plus trailing whitespace strips back to exactly the cap, so an arbitrarily large suffix passed the size check and the digest bound to a prefix. One snapshot: the manifest is parsed once, and the entries, documents and pinned class travel together through the analyzer, the worksheet and the verdict metadata, so replacing the file mid-run cannot leave them describing different material. The snapshot type carries the four pinned declarations — permission, scope, sample kind, access scope — because pinning permission alone would let a synthetic document ride under an authorised permission. Declaration rules moved into validate_entries and are re-applied to snapshot entries, so a hand-assembled wrapper cannot skip what parsing enforces. Regressions: suffix past the bounded read, symlinked root with the path check blinded, a read failure reporting corpus_entry_unusable once, a material-class mismatch, the manifest replaced after preflight, and a forged snapshot carrying source_trust or projection the loader would refuse.

charset=UTF-8 Content-Transfer-Encoding: 8bit The preflight read the manifest twice — once to classify an empty list, then again through load_manifest — so "read once, one snapshot" was not true of the file itself and a replacement between the two reads could leave the classification and the validated entries describing different files. Parsing is now split from reading: `parse_manifest_text` takes text and does the duplicate-key check, the list/empty classification and every declaration rule; `load_manifest` is a thin read-then-parse wrapper; an empty list raises `ManifestEmpty` so a caller can distinguish "declared nothing" from "will not parse". The preflight reads the file once and feeds that text to the shared parser. The declaration rules now live only in `validate_entries`, called by the parser for parsed entries and by the analyzer for snapshot entries, so the two cannot drift — the inline copies in load_manifest are gone. --- services/agent/e2e_citation_support_model.py | 33 ++++++----- services/agent/src/corpus_manifest.py | 58 +++++++++++--------- 2 files changed, 53 insertions(+), 38 deletions(-) diff --git a/services/agent/e2e_citation_support_model.py b/services/agent/e2e_citation_support_model.py index 4f8e419ee9..221839da45 100644 --- a/services/agent/e2e_citation_support_model.py +++ b/services/agent/e2e_citation_support_model.py @@ -32,7 +32,12 @@ sys.path.insert(0, str(Path(__file__).parent / "src")) from citation_review import build_worksheet, load_verdicts, summarize -from corpus_manifest import ManifestError, load_manifest +from corpus_manifest import ( + ManifestEmpty, + ManifestError, + load_manifest, + parse_manifest_text, +) from deepseek_model import ( DeepseekModel, ModelProtocolError, @@ -289,8 +294,9 @@ def _corpus_override() -> ValidatedCorpus | None: snapshot, so retrieval, the worksheet and the verdict metadata all describe the same material even if the file is replaced mid-run. - Declarations come first (`load_manifest` checks permission, scope, projection and - source trust), and every entry must declare exactly the material class this run + Declarations come first (`parse_manifest_text` checks permission, scope, projection + and source trust — the same rules `load_manifest` applies), and every entry must + declare exactly the material class this run pins — permission, scope, sample kind and access scope.

From 183321b8eeff9c230928e45b1507089e593001ab Mon Sep 17 00:00:00 2001 From: DavidHLP Date: Mon, 28 Sep 2026 18:03:41 +0800 Subject: [PATCH 16/34] fix: bind the override at preflight and refuse an unreachable threshold MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three review findings on the snapshot-consistency commit. The preflight returned a ValidatedCorpus without ever binding entries to documents, so a manifest whose content_digest or chunk_id disagreed with its own files survived until analyze_authorized_submission — after the login and submission scan — and surfaced as a generic ManifestError instead of the documented corpus reason. The binding now runs at preflight and ManifestError normalises to corpus_entry_unbound. Raising ULTICODE_CITATION_REQUIRED_ROWS above three could never be reached: retrieval caps at MAX_RESULTS, so the run always reported insufficient_citations no matter the material. A threshold above the retrieval limit is now refused with its own reason, before any gap comparison. A declared source_path containing a NUL makes os.open raise ValueError before a descriptor exists; the handler only caught OSError, so the workflow emitted error=ValueError. It is now corpus_entry_unusable like every other malformed entry. Red-first: with the fixes disabled the three regressions fail on the old reason, on `insufficient_citations emitted=3 required=4`, and on `error=ValueError`. Suite 499 passed / 1 skipped.
