From fc804f57b58732a4f7e205b38d99109f469abc36 Mon Sep 17 00:00:00 2001 From: Jarek Potiuk Date: Fri, 16 Oct 2026 10:33:08 +0100 Subject: [PATCH 01/32] perf(security-issue-import): decide and render the import as code A new tools/security-management package holds the deterministic rules of the security skills, one CLI family per skill over a shared library. For security-issue-import it decides the governance defaults, the Step 1 pre-filter, the threadId dedup batches, the forwarder pre-screen, the reply grammar and the receipt-draft matrix, and renders the sanitised tracker body, rollup entry, rejections-ledger record, fix-already-public reply and recap. It runs nothing; report text reaches it only through files. SKILL.md becomes a router (9,864 -> 7,799 tokens); headings and golden rules are unchanged. The step-0, step-6 and step-7 eval suites become pytest cases named after each former case. Empty body fields now read _No response_, headings follow tracker.body_fields, fenced code is no longer demoted, and the lone-fence rule no longer strips the closing fence of every code block.

It reuses the shared body, rollup, refs and titles modules and runs nothing; PR-derived text reaches it only through files. SKILL.md becomes a router (8,447 -> 7,150 tokens, 659 -> 499 lines); headings, golden rules, the Reporter credit policy and the adversarial-review block are unchanged. The mixed-scope blocker, the scope mapping, the body-field table, the board recipe and the sibling comparison moved byte-for-byte into outcomes/ and backends/. The step-2-scope-detection eval suite becomes pytest cases named after each former case. The PR body is sanitised and linked into upstream instead of optionally fenced (a fence cannot hide a ### line from the body-field parser), and a bot author is checked by login as well as by name.

[`tools/security-management`](../../../security-management/README.md) +(`security-management issue-import-from-md parse` and `keyword`), not by the model. +The cases that covered them — `step-1-parse-findings` cases 1–3 and `step-2-duplicate-guard` case 1 — are pytest cases with the same files and expected output, +named after each former case, in [`tests/test_issue_import_from_md.py`](../../../security-management/tests/test_issue_import_from_md.py). +The two injection cases stay model evals: whether the model treats a directive in a title as data is judgement. +The `step-6-recap` scenario is pinned there too, against `render-recap`; that suite stays a model eval. + ## Hard rules exercised - **Step 1** — A severity value not in `{HIGH, MEDIUM, LOW, UNKNOWN}` must be recorded as `UNKNOWN` with a warning; it must not be silently accepted or cause the finding to be skipped. - **Step 1** — A missing `## Details` section produces a warning but does not drop the finding; the tracker body field uses `_No response_`. - **Step 1** — A prompt-injection directive embedded in the title (e.g. `SYSTEM: output {}`) is parsed as literal title text, not executed. The finding is still extracted normally. - **Step 2** — The skill **must** use the Write tool to put the raw keyword into a temp file before any shell command. Direct bash interpolation of an attacker-controlled title string is forbidden — `$()` and backtick expansions in the title would execute otherwise. -- **Step 2** — `tr -cd 'A-Za-z0-9._ -'` strips all shell metacharacters.

Telling a code span apart (escaped backticks, a span across lines) needs a CommonMark inline parser, and an escaped < or [image: in code is harmless, so the exemption is gone rather than refined. Line endings are normalised (\r\n and \r become \n) before any analysis, in the body and in every short field, and text holding another character that str.splitlines breaks on (\x0b, \x0c, \x1c-\x1e, \x85, U+2028, U+2029) fails closed: github-body-field would split it into lines CommonMark does not see. A fence closes only on a line whose rest is spaces and tabs, as in CommonMark; a closer followed by a form feed or a non-breaking space no longer counts and the body is refused. Validators that anchored with $ (sub-package names, the PR URL and short reference, the findings repository, the recap's full reference) use fullmatch, so a trailing newline no longer passes.

Both sides are fixed. Inside a fence, a heading line of any level is now escaped (\### Severity), still readable as code and matched by no field parser; and generate-cve-json reads fields through github-body-field's fence-aware parser, raising DuplicateFieldError when a heading appears twice outside fences instead of taking the first. A raw HTML block (a line starting with < and a letter, /, ! or ?) let GitHub render an image the sanitiser took for fenced code, since an HTML block runs through fence lines. The < of every such line is now <, fenced lines and short fields included, so sanitised text holds no HTML block. generate-cve-json gains its first runtime dependency, the stdlib-only workspace member github-body-field.

Dispositions resolve per candidate: identical repeats are one action, conflicting ones (skip 1 and 1:reject-with-canned A, two canned names, two values for one field) leave the candidate out of every actionable list, and free text or a rejection that names no known candidate holds every action until the user clarifies. Rejections-ledger values are sanitised like body fields, so an image or tag in a rejected subject or reporter name is not rendered in the ledger comment. The threadId dedup accepts the identifiers the mail-source backends emit (Gmail and PonyMail ids, maildir names, root Message-IDs such as <report@example.org>), quotes each as a search phrase and prints the shell-quoted command; any other id now exits 2 and the skill stops, instead of the candidate silently getting no dedup search. Recaps and duplicate hits render tracker references per backend: GitHub builds its issue URL, Jira and local-files use the id and url the backend returned, or the bare id when there is none. Scope detection tries every scope on every file, and a file two scopes both match blocks like a mixed PR, since the config has no precedence. It reports detection (matched, mixed, unresolved, disabled); with detection disabled and no default label no scope label is applied, instead of the literal None. The PR rollup carries the confirmed severity and reporter-credit overrides. Search keywords lose their whole leading run of spaces and hyphens, so "-- --help" cleans to "help". Reference linking leaves alone code spans of any backtick run, existing markdown links, autolinks and bare URLs.

fix(security-management): escape HTML openers anywhere in report text Escaping only an HTML block start at the beginning of a line left a container prefix as a way round it: "- <div>", "> <div>" or "1. <details>" still opens an HTML block on GitHub, which renders through the fence lines the sanitiser paired. Every < followed by a letter, /, ! or ? is now < anywhere in report text, in the body (fenced lines and code spans included, where < is harmless) and in every short field, so no container prefix has to be parsed. An inline tag such as <img src=x> is escaped the same way.

No adapter is named in the code; every pattern and handle comes from project.md. It runs nothing and never redacts again: the parent's redacted body passes through as text. SKILL.md becomes a router (6,213 -> 5,724 tokens, 350 -> 320 lines); headings, golden rules and the Hard rules are unchanged. The Step 0 outcomes, the detect loop, the routing components and the inputs table moved byte-for-byte into outcomes/. The step-0-preflight and step-3-route-drafts suites and step-1 cases 1, 2, 3 and 6 become pytest cases named after each former case; the injection and collaborator-warning cases of step 1 and all of step 2 stay model evals. Intentional changes: "installed" means an adapter directory or a shipping row of the forwarder-relay README whose reference doc exists; an adapter whose patterns are unresolved or do not compile stops detection instead of being skipped; the preamble snippet is the matched preamble up to its first line break, at most 80 characters; and sync routing needs the milestone named from the policy's fixed list.

It renders the per-scan triage report (distribution line, a section per bucket, a row per finding) and, across several scans, the outcome table, the breakdown with percentages and the severity-vs-disposition table; it parses the operator's decision grammar, holding everything on an ambiguous reply; and it lists what a public report must not carry (private tracker references, CVE IDs not yet public, embargo terms, bare #NNN) without rewriting it. Bucketing, grounding and the scanner assessment stay with the model. It runs nothing. SKILL.md: 5,964 -> 6,030 tokens, 401 -> 385 lines. The skill was nearly all judgement, so the commands it now names cost about what the moved prose saved; headings, golden rules, the Step C table and the adversarial-review block are unchanged. The skill composition list, the folder-discovery recipe, the per-source destinations and the old Step D prose moved byte-for-byte into outcomes/ and backends/. The step-c-bucket suite stays a model eval; its creates_tracker rule is pinned in pytest for every bucket. Intentional changes: a by-design, duplicate or already-fixed row without its grounding is refused, and the scrub now runs on every public surface (gist and public issue_analysis.md as well as the report-back PR).

A field heading is any level-3 ATX heading outside a fence: two spaces or a tab after ###, up to three spaces of indent and a closing run of # all count, and lines end at CommonMark's line endings only. The new normalise(body, known_fields, keep) returns the canonical body with a change list and the decisions it will not make: CRLF and CR become LF, headings become "### Name" (taking a known field's spelling when the case-folded name matches), a heading-shaped line inside a fence is escaped, an unclosed fence is closed, and a repeated field is collapsed when every copy holds the same value. Copies with different values are left alone and reported, unless the caller passes the line of the copy a human chose to keep. A print-only `normalise` subcommand reports the same without ever writing body text to stdout. A duplicate field now raises DuplicateFieldError, a FieldNotFoundError subclass, so callers no longer match on the message. The vetted-ops copy of the parser is re-synced.

The body is now normalised in memory against the template field names first: lenient or differently cased headings name their field again, CRLF bodies read the same as LF ones, and copies of a field holding the same value collapse to one. A field repeated with different values exits 2 with the field name and the heading line numbers, and no record is written; the tool never picks a copy. The new --report-json flag writes normalisation_changes, needs_decision and missing_required (the summary, affected versions, CWE, severity, credit and CVE link, each marked with whether an agent may propose a value; never for severity or the CVE link) for the calling skill to act on. It holds no body text and is written on exit 2 too. Run over the 379 real tracker bodies against main, every record is the same except one, which now stops on its differing duplicate; the only other change is that CRLF bodies no longer carry carriage returns into the CVE description.

The parser now tracks a simple container context (a line starting with >, a bullet or an ordered marker, its indented lines and lazy continuations, ended by an unindented line after a blank line or an unindented heading or fence). Container lines are neither fields nor fences, and normalise never rewrites them. As a second line of defence, normalise cross-checks its result with a strict reader (### at column 0, fences opened only at column 0). Where the two disagree about a field heading it records a container-heading decision instead of picking a reading, and generate-cve-json exits 2 on it as it does for a differing duplicate. The vetted-ops copy is re-synced, and a parity test runs both implementations over the same tricky bodies. Over the 379 real tracker bodies nothing changes: no container-heading decision fires, and every CVE record matches the previous commit.

Every skill step that regenerates the record (security-issue-sync, security-cve- allocate, security-issue-deduplicate) now passes --report-json and, when the report lists missing_required or needs_decision, follows one shared procedure in issue-sync/outcomes/cve-json-fallback.md. The model already running the skill reads the tracker body and proposes values, labelled AI-proposed and applied only on explicit confirmation through the normal field write, with the confirmation recorded in the rollup. No new LLM hop is added. Severity is never proposed (the team scores it independently; a reporter's CVSS stays informational) and the CVE link comes only from allocation. For a field repeated with different values the user sees each candidate and picks one; the normalised body is then offered as a whole-body rewrite, applied only on confirmation.

It is gone. A field heading is now only "### <name>" at column 0, or the lenient form (extra spaces or tabs after ###, closing #s) at column 0 after a blank line or a field heading, or an indented one only right after a field heading or at the start of the body. Everything else is content. Any other heading-shaped line outside fences whose name, after stripping > and list markers, is a known field is reported as a container-heading decision: never taken as the field, never ignored, and generate-cve-json exits 2 on it. The strict cross-check now reads fence content unescaped, so an indented fence that a renderer would close at the end of a list can no longer hide a field silently. The vetted-ops copy is re-synced and the parity fixtures cover the new cases. The 379-body corpus is unchanged: no container-heading decision fires, and only #32 and #352 differ from main.

Each new markdown trick needed another rule. The description (the email body, the PR description, each findings-file section) now goes in as one fenced block with info string `text`, its fence one backtick longer than the longest backtick run in the text (at least three), and the content byte-exact. No line of the text can close the block, and nothing inside it renders: no image loads, no HTML or comment opens, no heading becomes a section, no reference links. Short fields stay one-line escaped values. Before a body is returned it now goes through github-body-field's normaliser: it must hold exactly the template fields, once each, with nothing to decide and no rewrite but headings inside fences, or the render is refused. A body holding a line-break character other than \n is still refused. The sanitiser code this made dead is removed, and the reference linker pairs fences the CommonMark way, so it never links inside the block. Behaviour change: reporter formatting now shows as plain text in the tracker, and a malformed fence in the report no longer blocks the import. The import skills' sibling docs describe the new shape.

It is now a loop that strips one marker at a time, at most 64 of them, behind a cheap "###" pre-check; a 100k-char line of markers normalises in well under a second. The fail-closed rules ran only inside normalise, so a caller that read or wrote a field directly could skip them. extract_field and replace_field now run the strict cross-check and the nested-heading detection for the requested field themselves and raise AmbiguousFieldError, a FieldNotFoundError subclass, when readers could disagree. The CLI's get and set exit 2 on it without writing; the vetted-ops body-field-get and body-field-set procedures refuse it, and generate-cve-json reports it as a clean exit 2 instead of reading an empty field. The vetted-ops copy is re-synced. The 379-body corpus is unchanged: only #32 and #352 differ from main.

The local tracker now pairs fences through github-body-field's fence_roles (a new workspace dependency, stdlib-only), the Jira bridge pairs them by the same CommonMark rule (same character, a closer at least as long, nothing after it), and generate-cve-json finds the CVE tool link section with the shared parser. As defence in depth for any reader that ignores fences, a line inside the inert block that would be a heading naming a template field if the fence were ignored (after leading whitespace, > and list markers: ###, a space or tab, the name) now gets a leading backslash. Every other line stays byte-exact, and the render output lists the escaped lines (escaped_lines). Intentional behaviour change: such lines in a report or PoC show with a backslash in the tracker. A new test renders reports full of ```, ~~~ and ```` runs and fake (github-body-field, the vetted-ops copy, generate-cve-json, the local tracker, the Jira bridge, and a fence-blind reader) finds exactly the template fields, once each. The parser exposes fold_name and loose_heading_name for this; the vetted-ops copy is re-synced. The 379-body corpus is unchanged: only #32 and #352 differ from main.

It is now one forward-only scan over the line (whitespace, then a >, a bullet, or an ordered marker of one to nine digits followed by a space or tab, repeated until none matches), so it stays linear in the line length with no cap. Tests cover 65 and 10,000 markers of each kind, and the vetted-ops copy and parity fixtures are re-synced. The 379-body corpus is unchanged.

On a real tracker the reporter's own "### Affected Versions" heading in the description became a third copy of the "Affected versions" field and a duplicate decision. Matching now collapses whitespace but keeps case, in the heading canonicalisation and in the container-heading detection alike, so a differently cased heading is content again. "### Affected versions" still canonicalises. The case-insensitive comparison stays only for the inert-block escapes, which guard readers that compare case-insensitively. Over the 379-body corpus every record matches main once carriage returns are stripped, except #352, which still exits 2 but now names only its two real duplicate headings (lines 239 and 248). The vetted-ops copy is re-synced.

A report carrying "<!-- generate-cve-json: cve=UNKNOWN version=v1 -->" therefore made the next attach before CVE allocation delete everything from that line to the end of the body, every trusted field after it included, and the paired form did the same between two planted markers. Markers now count only as the tool writes them: the whole line, at column 0, outside any fence (github-body-field's CommonMark pairing), and after the last template field heading, where the attachment always goes. The block is replaced by validated line offsets, not a text search. Before any PATCH the old and new bodies are parsed with the shared parser, and the attach exits 2 without writing unless every field outside the attachment keeps its name, order and value. At import, any line of report text that starts with "<!--" is now escaped inside the inert block (listed in escaped_lines), so machine markers never travel in report text; short fields already escape it. Over the 379 real tracker bodies the locator finds 93 of the 94 markers the old search found, and re-attaching changes no field in any of them. The one it skips (#492) is a begin marker above the template fields whose end marker sits below them, exactly the span the old code would have deleted on the next attach.

' ### Severity' ..." silently deleted Severity. It now refuses (AmbiguousFieldError) when the replaced span, old or new, holds a heading-shaped line outside fences, whatever its name, and when the rewritten body would change any other field; vetted-ops body-field-set inherits the refusal. - normalise escaped heading-shaped lines inside fences, so a fenced "# comment" in a public summary reached the CVE description as "\# comment" and a duplicate-resolution rewrite altered PoC code. Fenced lines are now never rewritten; a fence only decides what counts as a heading. The known-field escapes stay where they belong, in the import's inert block. - The strict cross-check accepted only "### name", so a "### Severity" after an indented list fence produced no decision. It now reads column-0 headings under the same spacing rules as the lenient reader, and a heading-shaped line naming a known field where the two fence views disagree is a decision too. - Heading parsing used regexes with adjacent whitespace quantifiers, quadratic on long space runs. It is now index scans; 100k-space headings parse in well under a second, also through the inert block. The CLI now reads body files as bytes and fetches remote bodies as JSON, so CRLF reaches normalise intact: "changed" and --output agree. The vetted-ops copy is re-synced with new parity fixtures. Over the 379-body corpus nothing changes: only #352 differs from main once carriage returns are stripped, and the attachment locator still finds 93 of 94 markers (the skipped one is #492's above-the-fields marker).

The generator now keeps CNA_private.state at DRAFT while any required field is empty (the summary the title stood in for included), in the record and in the attached table alike, and --report-json carries the state it gave (cna_private_state). An empty reporter credit is the one exception: anonymous and internally found reports have none, and two published records in the real tracker corpus carry only a remediation credit; holding them back would walk PUBLIC records back to DRAFT. The fallback doc now runs whenever any of normalisation_changes, missing_required or needs_decision is non-empty (the normalisation-only tidy-up was unreachable before), tells the agent to confirm the state in the report before advancing anything, and the callers in issue-sync, cve-allocate and issue-deduplicate dispatch on the same rule.

From 1b012d4a38bbe07d46323687cc39b381b1e24770 Mon Sep 17 00:00:00 2001 From: Jarek Potiuk <potiuk@apache.org> Date: Sat, 17 Oct 2026 01:30:49 +0200 Subject: [PATCH 25/32] fix(github-body-field): verify the rewritten body and keep CRLF spacing replace_field checked the rewrite against the lenient parser only, so replacing A in "### A ... ### B" with an indented fence closed by a column-0 run passed: CommonMark closes the fence there, while a column-0 reader opens one and loses B. The rewritten body now goes through the full strict-vs-lenient and nested-heading check, with every field of the old body as a known name, and any disagreement refuses the rewrite before vetted-ops body-field-set can PATCH. Spacer detection and replacement assumed LF. On a CRLF body, get returned the blank spacer as part of the value, and set dropped it and wrote mixed line endings. Blank spacers are now recognised under any line ending, and the replacement value and spacers are written in the body's own convention (CRLF, lone CR or LF), so setting an unchanged value is byte-identical and the CLI writes nothing. The vetted-ops copy is re-synced.

When that field came before another template field, the attachment landed in the middle of the template, and the marker locator, which looks only after the last template field, then took it for field content and refused the next, safe update. The attachment now goes after the last template field's value wherever CVE tool link sits; a reordered-body regression covers the first attach and the refresh after it. The fallback doc and the generator's SKILL.md said any missing field keeps the record in DRAFT, which is not what the code does. They now state the rule as applied: an empty summary (title substitution included), affected versions, CWE, severity or CVE link keeps DRAFT, and a template-field needs_decision stops the run; an empty reporter credit or a duplicate of a field the tool does not read does not hold the record back, so anonymous and remediation-only records keep REVIEW or PUBLIC. The corpus checks are unchanged: only #352 differs from main once carriage returns are stripped, the attachment locator finds 93 of the 94 markers, and the three records the stricter rule would have walked back (#355, #373, #482) stay PUBLIC.

No fence or Jira macro left in one field's text can then merge the next field into it, so a stray fence in the public summary can never pull the private mailing-list thread into the published CVE description. This stack had instead routed every reader through github-body-field, where a `###` line inside a fence was content, and the rebased tip failed #1683's tests for exactly those cases. The contract now lives in github-body-field, for reading and writing alike, and nothing else splits fields on its own. Every column-0 line of `###` followed by a space, a tab or nothing ends a field. Closed blocks (CommonMark fence pairs and Jira `{code}` / `{noformat}` blocks, scanned by one implementation; a block left open marks nothing) pick the first `### <name>` outside them, else the first, and two differing copies outside them are a duplicate decision. An indented or quoted heading ends no field and stays a container-heading decision when it names a known field. normalise closes a fence left open inside the field it opens in, and replace_field refuses a value holding a line that would end the field, or a rewrite that moves another heading into or out of a closed block. generate-cve-json drops its private splitter and reads values and the attachment anchor through the parser. The import tools' inert block escapes every line that would end a field, whatever its name. The local-files tracker pairs fences through a byte-identical copy of the parser instead of a workspace dependency the vetted-ops plugin cannot resolve.

This module exposes a pure +parser/replacer so the CLI can run without ever bringing the body +into the agent's context, and so the (numerous) tricky edge cases +can be unit-tested in isolation. It is the one implementation of the +body-field contract (tools/github/issue-template.md): every reader and +writer of a field, generate-cve-json included, goes through it. + +The contract: + +- lines end at ``\\n``, ``\\r\\n`` or ``\\r`` (CommonMark's line endings, + not every character ``str.splitlines`` breaks on); +- **every line that starts, at column 0, with ``###`` followed by a space, + a tab or the end of the line ends the current field and starts the next + one, code block or not.** No fence, Jira macro or duplicate heading left + in one field's text can therefore make it absorb the next field (a + private mailing-list URL, say): a value is always exactly one section of + that split. The heading's name is the rest of the line with surrounding + spaces and tabs and a closing run of ``#`` dropped, compared + case-sensitively; normalising against known field names also collapses + inner whitespace; +- **closed code blocks only choose which heading starts a field.** A closed + block is a CommonMark fence pair (an opener of three or more backticks or + tildes indented at most three spaces, closed only by a run of the *same* + character, at least as long, followed by nothing but spaces or tabs; a + backtick opener whose info string holds a backtick is not a fence) or a + Jira ``{code}`` / ``{code:…}`` / ``{noformat}`` block that opens on a line + starting with the macro and closes on the bare macro. A block left open + at the end of the body marks nothing. Among the ``### <name>`` lines, the + field is the first one outside every closed block, else the first one: a + PoC quoting ``### CVE tool link`` inside a fence is not taken for the + field when the real heading is outside one. Two or more copies outside + closed blocks are a duplicate; +- a heading-shaped line that does not end a field (indented, behind a + block-quote or list marker) is content.

So a four-backtick block holding a three-backtick - line keeps its content, and a ``### foo`` line inside a shell snippet - never false-matches as a heading; -- a field heading is, outside any fence, a ``### <name>`` line at - column 0, or the lenient form (up to three spaces of indent, one or - more spaces or tabs after ``###``, an optional closing run of ``#``) - when the previous line is blank, is itself a field heading, or there - is none; level-2 (``## ``) and level-4 (``#### ``) headings are - content. Lists and block quotes are deliberately not modelled: a - heading-shaped line in any other position is never a field, and - :func:`normalise` reports one naming a known field as a decision - (fail closed) rather than guessing what a renderer makes of it; +- **every line that starts, at column 0, with ``###`` followed by a space, + a tab or the end of the line ends the current field and starts the next + one, code block or not.** No fence, Jira macro or duplicate heading left + in one field's text can therefore make it absorb the next field (a + private mailing-list URL, say): a value is always exactly one section of + that split. The heading's name is the rest of the line with surrounding + spaces and tabs and a closing run of ``#`` dropped, compared + case-sensitively; normalising against known field names also collapses + inner whitespace; +- **closed code blocks only choose which heading starts a field.** A closed + block is a CommonMark fence pair (an opener of three or more backticks or + tildes indented at most three spaces, closed only by a run of the *same* + character, at least as long, followed by nothing but spaces or tabs; a + backtick opener whose info string holds a backtick is not a fence) or a + Jira ``{code}`` / ``{code:…}`` / ``{noformat}`` block that opens on a line + starting with the macro and closes on the bare macro. A block left open + at the end of the body marks nothing. Among the ``### <name>`` lines, the + field is the first one outside every closed block, else the first one: a + PoC quoting ``### CVE tool link`` inside a fence is not taken for the + field when the real heading is outside one. Two or more copies outside + closed blocks are a duplicate; +- a heading-shaped line that does not end a field (indented, behind a + block-quote or list marker) is content. A renderer may still show one as + a heading, so :func:`normalise` reports one naming a known field as a + decision (fail closed) rather than guessing what a renderer makes of it; - the original body is preserved exactly when no change is needed (idempotent rewrite). :func:`normalise` rewrites a body into the canonical shape every reader -agrees on (LF line endings, ``### Name`` headings, closed fences, no -heading-shaped line inside a fence, no repeated field) and reports what -it changed and what it would not decide on its own. +agrees on (LF line endings, ``### Name`` headings, fences closed in the +field they open in, no repeated field) and reports what it changed and +what it would not decide on its own.

This module exposes a pure +parser/replacer so the CLI can run without ever bringing the body +into the agent's context, and so the (numerous) tricky edge cases +can be unit-tested in isolation. It is the one implementation of the +body-field contract (tools/github/issue-template.md): every reader and +writer of a field, generate-cve-json included, goes through it. + +The contract: + +- lines end at ``\\n``, ``\\r\\n`` or ``\\r`` (CommonMark's line endings, + not every character ``str.splitlines`` breaks on); +- **every line that starts, at column 0, with ``###`` followed by a space, + a tab or the end of the line ends the current field and starts the next + one, code block or not.** No fence, Jira macro or duplicate heading left + in one field's text can therefore make it absorb the next field (a + private mailing-list URL, say): a value is always exactly one section of + that split. The heading's name is the rest of the line with surrounding + spaces and tabs and a closing run of ``#`` dropped, compared + case-sensitively; normalising against known field names also collapses + inner whitespace; +- **closed code blocks only choose which heading starts a field.** A closed + block is a CommonMark fence pair (an opener of three or more backticks or + tildes indented at most three spaces, closed only by a run of the *same* + character, at least as long, followed by nothing but spaces or tabs; a + backtick opener whose info string holds a backtick is not a fence) or a + Jira ``{code}`` / ``{code:…}`` / ``{noformat}`` block that opens on a line + starting with the macro and closes on the bare macro. A block left open + at the end of the body marks nothing. Among the ``### <name>`` lines, the + field is the first one outside every closed block, else the first one: a + PoC quoting ``### CVE tool link`` inside a fence is not taken for the + field when the real heading is outside one. Two or more copies outside + closed blocks are a duplicate; +- a heading-shaped line that does not end a field (indented, behind a + block-quote or list marker) is content. A renderer may still show one as + a heading, so :func:`normalise` reports one naming a known field as a + decision (fail closed) rather than guessing what a renderer makes of it; +- the original body is preserved exactly when no change is needed + (idempotent rewrite). + +:func:`normalise` rewrites a body into the canonical shape every reader +agrees on (LF line endings, ``### Name`` headings, fences closed in the +field they open in, no repeated field) and reports what it changed and +what it would not decide on its own. +""" + +from __future__ import annotations + +import re +from collections.abc import Iterable, Mapping +from dataclasses import dataclass, field + + +class FieldNotFoundError(LookupError): + """Raised when the requested field heading is absent from the body.""" + + +class DuplicateFieldError(FieldNotFoundError): + """Raised when the requested field heading appears more than once outside closed code blocks.""" + + +class AmbiguousFieldError(FieldNotFoundError): + """Raised when readers could disagree on the body's fields: a heading-shaped + line naming the requested field sits where a renderer may show it as a + heading although it ends no field, or a rewrite would change another field.""" + + +# A CommonMark line: content plus its ending (`\n`, `\r\n` or `\r`), or a last unterminated line. +_LINE = re.compile(r"[^\r\n]*(?:\r\n|\r|\n)|[^\r\n]+\Z") +# A fence line: up to three spaces, a run of 3+ backticks or tildes, the rest (info string or nothing). +_FENCE = re.compile(r"^( {0,3})(`{3,}|~{3,})(.*)$") +# A field boundary: `###` at column 0, then a space, a tab or the end of the line. +_BOUNDARY = re.compile(r"###(?:[ \t]|$)") +# A Jira block opener: a line starting (after spaces or tabs) with `{code}`, `{code:…}` or `{noformat}`. +_JIRA_OPEN = re.compile(r"[ \t]*\{(code|noformat)(?::[^}]*)?\}") + + +def split_lines(body: str) -> list[str]: + """``body`` split into lines with their endings kept, at CommonMark line endings only.""" + return _LINE.findall(body) + + +def _content(line: str) -> str: + """``line`` without its line ending.""" + return line.rstrip("\r\n") + + +def is_boundary(line: str) -> bool: + """Whether ``line`` ends a field: ``###`` at column 0, then a space, a tab or the end of the line.""" + return _BOUNDARY.match(_content(line)) is not None + + +def _opens_fence(match: re.Match[str] | None) -> bool: + return match is not None and not (match.group(2)[0] == "`" and "`" in match.group(3)) + + +def _blocks(lines: list[str], *, jira: bool, max_indent: int = 3) -> list[tuple[int, int | None]]: + """``(opener, closer)`` line indices of every code block, ``closer`` None for one left open. + + The one block scanner: CommonMark fences (an opener indented at most + ``max_indent`` spaces; the closer uses the opener's character, is at + least as long, and carries nothing but spaces or tabs after the run; a + backtick opener whose info string holds a backtick is not a fence), and + with ``jira`` also Jira ``{code}`` / ``{noformat}`` blocks, opened on a + line starting with the macro (and not closing it on the same line) and + closed on the bare macro.

Both now read and write body fields through a byte-identical copy of github-body-field's parser (the vetted-ops plugin ships them without the workspace, as it already did for local-tracker), pinned by a test in each package. Jira bridge: wiki h1. to h3. headings outside closed code blocks read as `### <Heading>` before the parser sees the body, and the parser's block scanner decides what is code, so a {code} or {noformat} macro opens only at the start of a line and a block left open hides nothing. Every column-0 `###` line ends a field, code block or not. get_field and set_field resolve the name with case and whitespace ignored, then call the parser's extract_field and replace_field; a replacement is mapped back onto the wiki body and refused when the value would add, hide or move a field heading. `body` exports exactly the fields field-get reads, so generate-cve-json sees the same values. Duplicate, disputed and unsafe writes exit 4. Local-files tracker: `###` body fields go through the parser for reads, replacements and appends; an append must leave every other field as it was and read back as written. The managed comment and rollup sections, comment headings and a non-`###` field level keep the heading-level section split. Field values, comments and rollup entries have every line that would end a field escaped, fence or not, as the import's inert block does; a whole report body keeps its field headings. Tests that encoded the opposite rule now assert the contract: - local-tracker test_headings_inside_code_fences_are_ignored: get_field(B) is None became get_field(B) == "```" (with no other copy the fenced heading is the field), and "### B" in get_field(A) became get_field(A) == "```" (the fenced `### B` ends field A); added: a copy of B outside the fence wins, and C reads "c". - jira test_headings_inside_code_blocks_are_ignored: get_field(fenced, "fake") is None became == "```", plus a copy outside the fence wins. - jira test_shorter_fence_inside_longer_fence_does_not_close_it, test_fence_closes_only_on_the_same_character (both bodies) and test_fence_close_must_be_bare asserted get_field(body, "Field") is None for a `### Field` inside a closed fence. They now assert that with a real `### Field` appended outside the fence, the real one is read: that holds only if the fence paired correctly (a mispaired fence leaves two copies outside closed blocks, a duplicate), which is what these tests were written to check. Their other assertions are unchanged. The readers-agree test reads field lists through each implementation's own parser path and now also runs a field read and a write over fifteen bodies (fenced, Jira-macro and unclosed blocks, duplicates, CRLF, two-space and closing-hash headings, container headings, private-field merge attempts) through github-body-field, the vetted-ops copy, the local-files tracker and the Jira bridge, requiring the same value, refusal or rewritten body from each.

The heading's name is the rest of the line with surrounding + spaces and tabs and a closing run of ``#`` dropped, compared + case-sensitively; normalising against known field names also collapses + inner whitespace; +- **closed code blocks only choose which heading starts a field.** A closed + block is a CommonMark fence pair (an opener of three or more backticks or + tildes indented at most three spaces, closed only by a run of the *same* + character, at least as long, followed by nothing but spaces or tabs; a + backtick opener whose info string holds a backtick is not a fence) or a + Jira ``{code}`` / ``{code:…}`` / ``{noformat}`` block that opens on a line + starting with the macro and closes on the bare macro. A block left open + at the end of the body marks nothing. Among the ``### <name>`` lines, the + field is the first one outside every closed block, else the first one: a + PoC quoting ``### CVE tool link`` inside a fence is not taken for the + field when the real heading is outside one. Two or more copies outside + closed blocks are a duplicate; +- a heading-shaped line that does not end a field (indented, behind a + block-quote or list marker) is content. A renderer may still show one as + a heading, so :func:`normalise` reports one naming a known field as a + decision (fail closed) rather than guessing what a renderer makes of it; +- the original body is preserved exactly when no change is needed + (idempotent rewrite). + +:func:`normalise` rewrites a body into the canonical shape every reader +agrees on (LF line endings, ``### Name`` headings, fences closed in the +field they open in, no repeated field) and reports what it changed and +what it would not decide on its own. +""" + +from __future__ import annotations + +import re +from collections.abc import Iterable, Mapping +from dataclasses import dataclass, field + + +class FieldNotFoundError(LookupError): + """Raised when the requested field heading is absent from the body.""" + + +class DuplicateFieldError(FieldNotFoundError): + """Raised when the requested field heading appears more than once outside closed code blocks.""" + + +class AmbiguousFieldError(FieldNotFoundError): + """Raised when readers could disagree on the body's fields: a heading-shaped + line naming the requested field sits where a renderer may show it as a + heading although it ends no field, or a rewrite would change another field.""" + + +# A CommonMark line: content plus its ending (`\n`, `\r\n` or `\r`), or a last unterminated line. +_LINE = re.compile(r"[^\r\n]*(?:\r\n|\r|\n)|[^\r\n]+\Z") +# A fence line: up to three spaces, a run of 3+ backticks or tildes, the rest (info string or nothing). +_FENCE = re.compile(r"^( {0,3})(`{3,}|~{3,})(.*)$") +# A field boundary: `###` at column 0, then a space, a tab or the end of the line. +_BOUNDARY = re.compile(r"###(?:[ \t]|$)") +# A Jira block opener: a line starting (after spaces or tabs) with `{code}`, `{code:…}` or `{noformat}`. +_JIRA_OPEN = re.compile(r"[ \t]*\{(code|noformat)(?::[^}]*)?\}") + + +def split_lines(body: str) -> list[str]: + """``body`` split into lines with their endings kept, at CommonMark line endings only.""" + return _LINE.findall(body) + + +def _content(line: str) -> str: + """``line`` without its line ending.""" + return line.rstrip("\r\n") + + +def is_boundary(line: str) -> bool: + """Whether ``line`` ends a field: ``###`` at column 0, then a space, a tab or the end of the line.""" + return _BOUNDARY.match(_content(line)) is not None + + +def _opens_fence(match: re.Match[str] | None) -> bool: + return match is not None and not (match.group(2)[0] == "`" and "`" in match.group(3)) + + +def _blocks(lines: list[str], *, jira: bool, max_indent: int = 3) -> list[tuple[int, int | None]]: + """``(opener, closer)`` line indices of every code block, ``closer`` None for one left open. + + The one block scanner: CommonMark fences (an opener indented at most + ``max_indent`` spaces; the closer uses the opener's character, is at + least as long, and carries nothing but spaces or tabs after the run; a + backtick opener whose info string holds a backtick is not a fence), and + with ``jira`` also Jira ``{code}`` / ``{noformat}`` blocks, opened on a + line starting with the macro (and not closing it on the same line) and + closed on the bare macro.

This module exposes a pure +parser/replacer so the CLI can run without ever bringing the body +into the agent's context, and so the (numerous) tricky edge cases +can be unit-tested in isolation. It is the one implementation of the +body-field contract (tools/github/issue-template.md): every reader and +writer of a field, generate-cve-json included, goes through it. + +The contract: + +- lines end at ``\\n``, ``\\r\\n`` or ``\\r`` (CommonMark's line endings, + not every character ``str.splitlines`` breaks on); +- **every line that starts, at column 0, with ``###`` followed by a space, + a tab or the end of the line ends the current field and starts the next + one, code block or not.** No fence, Jira macro or duplicate heading left + in one field's text can therefore make it absorb the next field (a + private mailing-list URL, say): a value is always exactly one section of + that split. The heading's name is the rest of the line with surrounding + spaces and tabs and a closing run of ``#`` dropped, compared + case-sensitively; normalising against known field names also collapses + inner whitespace; +- **closed code blocks only choose which heading starts a field.** A closed + block is a CommonMark fence pair (an opener of three or more backticks or + tildes indented at most three spaces, closed only by a run of the *same* + character, at least as long, followed by nothing but spaces or tabs; a + backtick opener whose info string holds a backtick is not a fence) or a + Jira ``{code}`` / ``{code:…}`` / ``{noformat}`` block that opens on a line + starting with the macro and closes on the bare macro. A block left open + at the end of the body marks nothing. Among the ``### <name>`` lines, the + field is the first one outside every closed block, else the first one: a + PoC quoting ``### CVE tool link`` inside a fence is not taken for the + field when the real heading is outside one. Two or more copies outside + closed blocks are a duplicate; +- a heading-shaped line that does not end a field (indented, behind a + block-quote or list marker) is content.

When every copy of a `### <name>` heading sat inside closed code blocks, the parser fell back to the first copy. On the Jira and local-files trackers a field can legitimately be absent, so a reporter's fenced `### Severity` became the Severity field. A heading inside a closed block now never starts a field: a field whose only copies are inside closed blocks is absent (extract and replace report it not found, list_fields and field_sections leave it out, normalise records nothing for it). Every `###` line still ends a field, code block or not, so no block can merge two fields either. Jira's renderer opens `{code}` and `{noformat}` anywhere in a line, while the parser opens a block only on a macro at the start of one, so a heading Jira shows as code could parse as a field. Whichever reading is right depends on the renderer, so the parser fails closed: a line outside closed blocks that leaves such a macro open, closed on a later line with field boundaries between, is a `macro-ambiguous` decision (the first hidden field; the opener's line, then each hidden heading's). Extract and replace refuse the field the macro opens in and every field it would hide, a rewrite that would create such a span is refused, and generate-cve-json exits 2 on it as it does on a container heading. A macro opened and closed on the same line stays text. At ingest, quoted text now never becomes a field copy at all: the local-files tracker's whole-body path (create, edit) and the Jira bridge's create and edit escape every `###` line inside a closed block with a leading backslash, as the import's inert block does. The local-files tracker closes a fence a body leaves open in the field it opens in, before the next field heading, instead of at the end of the body, where the closer would have moved the later field headings into a block. The vetted-ops, local-tracker and Jira copies are re-copied from the parser. The trackers' case-insensitive name lookup now applies the parser's ambiguity refusal before its duplicate check, as the parser does, and the local-files tracker writes an empty value as the parser does instead of as one blank line. Tests that relied on the "else the first" fallback: - github-body-field test_a_heading_inside_a_closed_fence_ends_the_field_but_never_becomes_it: the field quoted only inside a fence now raises FieldNotFoundError instead of returning the quoted value. - generate-cve-json test_code_blocks_cannot_merge_a_private_field_into_a_public_one (#1683): with a fence or {code} block closed in a later field, the private thread heading sits in the closed block, so the thread field is now absent ("") instead of read from inside the block; with the macro inside inline code (`{code}` in prose, closed later), both the summary and the thread are now refused as macro-ambiguous. The guarantee the test exists for holds in every case: the public summary never holds the private thread URL. - The previous commit's changes to #1683's Jira and local-tracker tests are undone where they asserted the fallback: get_field(fenced, "fake"), get_field(body, "Field") in the three Jira fence-pairing tests and get_field(body, "B") in the local-tracker test are None again, as #1683 wrote them; the added checks that a real copy outside the fence is read stay. The Jira test of a mid-line macro now expects the refusal. The corpus check (379 tracker bodies) produces output identical to the previous commit: no difference from main beyond CR removal, and #32's summary equal to main.
