+# doc-agent
+
+Automated documentation agent for the xrpld C++ codebase. Built on the
+Claude Agent SDK.
+
+## What it does
+
+Three modes:
+
+- **document** — Add Doxygen `/** */` documentation to a C++ file or
+  directory. For each target file, the agent reads the sibling
+  `<file>.ai.md` (high-signal prose generated by the athenah-ai pipeline),
+  the module skill, and the file itself, then writes Doxygen comments per
+  the standards in `docs/DOCUMENTATION_STANDARDS.md`.
+- **review** — Given a git diff range, detect documentation drift. Used by
+  the `doc-review` GitHub Action and locally for testing.
+- **regen-skills** — Rebuild a module's skill file at
+  `docs/skills/soul/<module>.md` from the `.ai.md` files in that module
+  and the existing skill content.
+
+## Requirements
+
+- Node.js >= 20.12 (for native `--env-file` support)
+- `ANTHROPIC_API_KEY` (in `.env` or exported in shell)
+- Tools the agent uses: `git`, `gh` (for `--pr`)
+
+## Install
+
+```sh
+cd .github/scripts/doc-agent
+npm install
+cp .env.example .env
+# edit .env and set ANTHROPIC_API_KEY
+```
+
+The npm scripts auto-load `.env` via Node's `--env-file-if-exists` flag.
+You can also export the variables in your shell — both work.
+
+## Build and lint
+
+```sh
+npm run typecheck     # type check without emitting
+npm run build         # compile to dist/
+npm run lint          # biome lint
+npm run format        # biome format --write
+npm run check         # lint + format check (read-only)
+npm run check:fix     # lint + format + fix
+```
+
+## Usage
+
+```sh
+# Document a single file (reads sibling .ai.md if present)
+npm run document include/xrpl/basics/base_uint.h
+
+# Document an entire module
+npm run document include/xrpl/basics/
+
+# Review a git range
+npm run review develop..HEAD
+
+# Review a PR
+npm run review -- --pr 1234
+
+# Regenerate a skill file from this module's .ai.md inputs
+npm run regen-skills protocol
+npm run regen-skills ledger
+```
+
+When invoked outside the xrpld repo, set `XRPLD_ROOT` in `.env` to the path
+of the checkout you want to operate on.
+
+## ai.md context files
+
+The doc-agent reads a sibling `<file>.ai.md` next to each source file when
+documenting it. These are produced by the upstream `athenah-ai` pipeline
+and treated as the authoritative source of intent. They are gitignored
+(`*.ai.md` in `.gitignore`) and should be removed once the initial
+documentation pass is complete.
+
+## Outputs
+
+The `review` mode writes two files in the current directory:
+
+- `doc-review-report.md` — markdown summary, posted as the PR comment
+- `doc-review-comments.json` — array of inline review comments, posted
+  individually on the PR diff
+

+    ├── regen-skills.ts      # Regen-skills mode
+    └── types.ts             # Shared types
+```
+
+## Module skills
+
+The agent injects per-module context from `docs/skills/soul/*.md` into its
+system prompt based on the file path being processed. The mapping lives in
+`src/config.ts` (`MODULE_SKILL_MAP`).
+
+## Notes
+
+- Prompts live in markdown files, not source, so they can be edited without
+  touching code.
+- The `document` mode uses `permissionMode: 'acceptEdits'` so the agent
+  writes directly to the target files. Run against a clean git tree so you
+  can review and revert if needed.

+You are auditing a C++ source file in the xrpld (XRP Ledger daemon)
+codebase to determine how completely the file's existing Doxygen
+documentation reflects the authoritative design intent captured in its
+sibling `.ai.md` file.
+
+This is a read-only audit. Do NOT modify the file.
+
+## Input
+
+You receive up to four pieces of context:
+- A **primary** C++ file (.h, .hpp, or .cpp) — the file this audit is
+  scoped to.
+- The **primary's `.ai.md`** — authoritative prose about the primary file's
+  purpose, design, invariants, failure modes, and non-obvious behavior.
+- A **partner** file — the header/source counterpart of the primary
+  (e.g., the `.h` partner of a `.cpp` primary), if one exists.
+- The **partner's `.ai.md`** — authoritative prose about the partner
+  file, if one exists.
+
+The **primary's `.ai.md`** is the source of truth for what concepts must
+be documented for the primary file. The partner's `.ai.md` is context:
+it tells you which concepts the project considers a *partner-file*
+responsibility (e.g., a "this class is the public contract for X" theme
+that naturally lives in the header). Use it to avoid flagging concepts
+that the project's own intent assigns to the partner.
+
+Documentation that satisfies a primary-file concept may live in **either**
+the primary file or the partner file — both count as "reflected." Header
+docs (the contract) and source docs (the implementation) together form
+the full documentation surface, so a concept covered on the header is
+not "missed" on the source even if the primary is the source.
+
+## Task
+
+For every distinct concept, invariant, design decision, state transition,
+ordering constraint, or failure mode in the `.ai.md`, decide:
+
+1. **Where it belongs.** Each concept has a *correct home* in the
+   documentation:
+   - `"header"` — the public *contract*: what the function/class promises
+     to its caller. Examples: parameter meanings, return-value semantics,
+     thread-safety guarantees, when an exception is thrown, "this class
+     represents X". These belong on the declaration in the header.
+   - `"source"` — the *implementation*: algorithm, ordering of checks,
+     state transitions, internal invariants, failure modes, the **why**
+     behind non-obvious choices. These belong on the definition in the
+     `.cpp` file.
+   - `"either"` — concepts that are equally at home in either place
+     (e.g., a file-level `@file` block describing overall role).
+2. **Whether it is reflected** in the correct home. A concept is
+   reflected if a reader of that file's docstrings can understand the
+   same point without reading the `.ai.md`. Verbatim wording is not
+   required; equivalent meaning is enough. A concept whose correct home
+   is the source but only appears on the header is **not** correctly
+   placed — it should also (or instead) be on the `.cpp` definition.
+
+A concept is **missed** if it is silent, paraphrased so thinly the
+reader cannot rely on the docstring, or documented only in the wrong
+home (e.g., implementation depth on the header instead of the source).
+
+Do **not** flag implementation details the `.ai.md` does not call out as
+design-significant. Do **not** invent concepts not in the `.ai.md`.
+
+## Output
+
+Respond with **only** a JSON object — no prose, no markdown fences:
+
+```
+{
+  "file": "<path relative to repo root>",
+  "ai_md_concepts": <integer count of distinct concepts identified in the .ai.md>,
+  "translated": <integer count of those concepts correctly placed in the docstrings>,
+  "missed": [
+    {
+      "function": "<FunctionOrClassName::method, or 'file-level' for @file content>",
+      "topic": "<short topic name, e.g. 'Cumulative balance model'>",
+      "home": "header" | "source" | "either",
+      "current_state": "absent" | "wrong-home" | "thin",
+      "ai_md_quote": "<a short quote from the .ai.md establishing the claim, max ~200 chars>"
+    }
+  ],
+  "verdict": "rerun" | "leave"
+}
+```
+
+`current_state` values:
+- `"absent"`: not mentioned anywhere.
+- `"wrong-home"`: present in the partner file but not in the correct home
+  (e.g., implementation invariant lives on the header but not the source).
+- `"thin"`: mentioned in the correct home but too briefly to convey the
+  point.
+
+## Verdict rules
+
+The bar is 100% correctly placed coverage.
+
+- `"leave"` if and only if `missed` is empty — every `.ai.md` concept is
+  reflected in its correct home with adequate depth.
+- `"rerun"` otherwise. Any missed concept (absent, wrong-home, or thin)
+  produces a `"rerun"` verdict.
+
+Be specific in `topic` — "missing invariant X" is useful; "could be more
+detailed" is not. Quote the `.ai.md` directly in `ai_md_quote` so a
+human can verify the call. Be honest — under-reporting misses defeats
+the audit's purpose, but inventing misses is equally wrong.

+the generic reminder and proceed with the Edit tool to add comments.
+
+## Documentation Standards
+
+Read `docs/DOCUMENTATION_STANDARDS.md` for the full specification. Key rules:
+
+- Use `/** ... */` Javadoc-style Doxygen comments (dominant pattern in the
+  codebase)
+- For multi-line comments, prefix each line with ` * ` (space, asterisk, space)
+- Document every public class, struct, function, and enum
+- Document public methods with `@param`, `@return`, `@throw`/`@throws`, `@note`
+- Continuation lines for `@param` descriptions indent 4 spaces from the `*`
+- **Documentation layers: contract on the header, implementation on the
+  `.cpp`.** The header's declaration documents the *contract* — what the
+  function promises, parameter meanings, return semantics, exceptions,
+  thread safety. The `.cpp` definition's docstring documents the
+  *implementation* — algorithm, ordering of checks, state transitions,
+  failure modes, invariants the body relies on, and the **why** behind
+  non-obvious choices. These layers are complementary, never duplicative.
+- **Whether a `.cpp` function definition gets its own docstring is
+  decided by the `.ai.md`, not by style.** If the `.ai.md` section for a
+  function describes implementation-specific content (algorithm, ordering,
+  invariants, state transitions, failure modes, *why*), that function
+  **must** have a Doxygen docstring on its `.cpp` definition translating
+  that prose. Target 5–15 lines for substantive implementation. If the
+  `.ai.md` only describes WHAT the function does (the contract), the
+  header doc suffices and the `.cpp` definition does **not** need a
+  per-function docstring — adding one would just duplicate the header.
+  Use the `.ai.md` as the authoritative deciding factor, not your own
+  judgment about what looks documented.
+- `JAVADOC_AUTOBRIEF = YES` — the first sentence is automatically the brief,
+  so `@brief` is optional
+
+## Quality Rules
+
+- **Never paraphrase the signature.** `/** Returns the account ID. */` on
+  `AccountID getAccountID()` is worse than no doc.
+- **Document behavior, invariants, and the WHY.** What does this function do
+  in terms a developer can use? What can go wrong? What's the contract?
+- **Read the implementation before writing the doc.** Don't guess what the
+  function does — read it.
+- **Cross-reference test files** to find edge cases worth documenting in
+  `@note` tags.
+- **Length matches the layer.**
+  - **Header declarations** (the contract): be terse. 2–5 lines for
+    classes, 1–3 lines for free functions and public methods, plus tag
+    lines. The contract should fit on one screen.
+  - **`.cpp` function definitions** (the implementation): be thorough.
+    5–15 lines for non-trivial functions is normal. Capture algorithm,
+    ordering of checks, state transitions, failure modes, and the **why**.
+    The `.ai.md` Authoritative AI Context is your source — translate its
+    prose into Doxygen on the actual definitions; do not summarize it
+    away. A function whose `.ai.md` section is three paragraphs should not
+    end up with a two-line docstring.
+- **When you are not sure what the code does, the `.ai.md` is
+  authoritative.** Use what it says about that function rather than
+  skipping the docstring. Skipping is not a safe default — it leaves the
+  reader worse off than translating the `.ai.md`'s explanation onto the
+  declaration. Inventing facts not in the code, the `.ai.md`, the module
+  skill, or the tests *is* worse than no docs, but that is the only case
+  where "no doc" is the right answer for a non-trivial public entity.
+
+## Module Context
+
+Before you start, read the relevant skill file in `docs/skills/` for
+the module you're working on. These capture per-module conventions, key
+classes, and gotchas:
+
+- `basics`, `crypto`, `json`, `beast` — foundation utilities
+- `protocol` — STObject, SField, Serializer, TER codes, Features, Keylets
+- `ledger` — ReadView/ApplyView, state tables, payment sandbox
+- `tx` / `transactors` — transaction pipeline
+- `consensus`, `peering`, `nodestore`, `shamap`, `rpc` — see `docs/skills/`
+
+## Process
+
+Documenting a declaration is not the same as "writing a doxygen comment
+above it". It is producing the **total** set of comments that should
+surround the declaration after this pass — which includes the docstring
+and any inline comments that remain inside the function body or next to
+a data-literal initializer. Existing comments in the file are inputs,
+not outputs you are preserving.
+
+For each entity (class, struct, public method, free function in a header,
+enum, public field):
+
+1. **Read** the declaration, its full implementation, and **every comment
+   that is currently attached to it** — the Doxygen above it, any `//!`
+   line, any inline `// ...` annotations next to its initializer or
+   inside its body. Treat all of these as raw information about intent.
+2. **Cross-reference** the ai.md context (already injected in your
+   prompt) and the module skill file. Also grep for the entity's name
+   to find callers and tests where the behavioral contract is exercised
+   — those are often the best source of what to write.
+3. **Decide what the reader needs**, in this order:
+   a. A docstring that captures behavior, contract, invariants, and the
+      WHY. This is the primary deliverable.
+   b. Inline comments **only** where they document something the
+      docstring cannot reasonably hold — typically a non-obvious local
+      invariant, a workaround for a specific bug, a tricky branch whose
+      WHY is genuinely local. If the inline comment just narrates what
+      the next line does, it does not belong.
+4. **Produce a single edit** that replaces the entity's full comment
+   surface with the result of step 3. Concretely:
+   - If you wrote a docstring whose contents subsume an existing `//!`
+     or section-header prose comment, **remove** the old comment as part
+     of the same edit. Do not leave both.
+   - If you wrote a docstring whose `@note` or body covers the meaning
+     of an inline annotation on a map row, array literal, or magic
+     constant inside the entity, **remove** that inline annotation.
+     Leaving it duplicates what the docstring says.
+   - If you wrote a docstring on a function whose body has line-by-line
+     narration of control flow (`// check this`, `// now do that`),
+     **remove** the narration unless a specific line documents a real,
+     non-obvious WHY.
+   - Section banner comments (`// --- Avalanche tuning ---`) may stay as
+     short visual dividers if they help scanning a long struct, but any
+     multi-line prose in them that is now in the per-field Doxygen
+     should be cut.
+5. **Do not delete** comments that capture a WHY the docstring does not
+   cover: a workaround for a real bug, a non-obvious invariant local to
+   one branch, a reference to a ticket or RFC. If a pre-existing
+   comment contains information you did not put in the new docstring,
+   either fold it into the docstring or leave it in place.
+
+## Worked examples
+
+These show the exact transformations expected. The "AFTER" column is the
+state the file must be in when you finish. If your edit leaves the file
+in the "BEFORE" state, the pass has failed.
+
+### Example 1: section-header prose → short banner
+
+BEFORE:
+```cpp
+//-------------------------------------------------------------------------
+// Validation and proposal durations are relative to NetClock times, so use
+// second resolution
+
+/** Maximum age of a validation relative to its ledger's close time.
+ *  ... (rest of docstring already explains NetClock semantics) ...
+ */
+std::chrono::seconds const validationVALID_WALL = std::chrono::minutes{5};
+```
+
+AFTER:
+```cpp
+// --- NetClock-domain parameters ---
+
+/** Maximum age of a validation relative to its ledger's close time.
+ *  ... (rest of docstring already explains NetClock semantics) ...
+ */
+std::chrono::seconds const validationVALID_WALL = std::chrono::minutes{5};
+```
+
+The multi-line prose was redundant with the new per-field Doxygen and the
+file-level `@file` block. Replace with a single-line banner.
+
+### Example 2: inline annotations on a data literal → removed
+
+BEFORE:
+```cpp
+/** Avalanche state machine cutoffs.
+ *
+ *  | State  | Time | Yes-vote | Next   |
+ *  |--------|------|----------|--------|
+ *  | Init   | 0    | 50       | Mid    |
+ *  | Mid    | 50   | 65       | Late   |
+ *  ...
+ */
+std::map<AvalancheState, AvalancheCutoff> const avalancheCutoffs{
+    // {state, {time, percent, nextState}},
+    // Initial state: 50% of nodes must vote yes
+    {AvalancheState::Init,  {.consensusTime = 0,   .consensusPct = 50, .next = AvalancheState::Mid}},
+    // mid-consensus starts after 50% of the previous round time, and
+    // requires 65% yes
+    {AvalancheState::Mid,   {.consensusTime = 50,  .consensusPct = 65, .next = AvalancheState::Late}},
+    // ...
+};
+```
+
+AFTER:
+```cpp
+/** Avalanche state machine cutoffs.
+ *
+ *  | State  | Time | Yes-vote | Next   |
+ *  |--------|------|----------|--------|
+ *  | Init   | 0    | 50       | Mid    |
+ *  | Mid    | 50   | 65       | Late   |
+ *  ...
+ */
+std::map<AvalancheState, AvalancheCutoff> const avalancheCutoffs{
+    {AvalancheState::Init,  {.consensusTime = 0,   .consensusPct = 50, .next = AvalancheState::Mid}},
+    {AvalancheState::Mid,   {.consensusTime = 50,  .consensusPct = 65, .next = AvalancheState::Late}},
+    // ...
+};
+```
+
+The per-row inline comments restate the table that is now in the
+docstring above. They go. The schema comment `// {state, {time, percent, ...}}`
+also goes — the designated-initializer field names make the schema obvious.
+
+### Example 3: body narration in a documented function → removed
+
+BEFORE:
+```cpp
+/** Query the avalanche state machine.
+ *  ...
+ *  @note `at()` calls on `avalancheCutoffs` are safe because the map is
+ *      constructed with all four valid keys.
+ */
+inline std::pair<...> getNeededWeight(...)
+{
+    // at() can throw, but the map is built by hand to ensure all valid
+    // values are available.
+    auto const& currentCutoff = p.avalancheCutoffs.at(currentState);
+    // Should we consider moving to the next state?
+    if (currentCutoff.next != currentState && currentRounds >= minimumRounds)
+    {
+        // at() can throw, but the map is built by hand to ensure all
+        // valid values are available.
+        auto const& nextCutoff = p.avalancheCutoffs.at(currentCutoff.next);
+        // See if enough time has passed to move on to the next.
+        XRPL_ASSERT(...);
+        if (percentTime >= nextCutoff.consensusTime)
+        {
+            return {nextCutoff.consensusPct, currentCutoff.next};
+        }
+    }
+    return {currentCutoff.consensusPct, {}};
+}
+```
+
+AFTER:
+```cpp
+/** Query the avalanche state machine.
+ *  ...
+ *  @note `at()` calls on `avalancheCutoffs` are safe because the map is
+ *      constructed with all four valid keys.
+ */
+inline std::pair<...> getNeededWeight(...)
+{
+    auto const& currentCutoff = p.avalancheCutoffs.at(currentState);
+    if (currentCutoff.next != currentState && currentRounds >= minimumRounds)
+    {
+        auto const& nextCutoff = p.avalancheCutoffs.at(currentCutoff.next);
+        XRPL_ASSERT(...);
+        if (percentTime >= nextCutoff.consensusTime)
+        {
+            return {nextCutoff.consensusPct, currentCutoff.next};
+        }
+    }
+    return {currentCutoff.consensusPct, {}};
+}
+```
+
+Every removed comment was either restating what the next line does
+(`// Should we consider moving to the next state?` on an `if`) or
+duplicating the docstring's `@note` (`// at() can throw...`). None of
+them documented a non-obvious WHY local to that line.
+
+### Calibration: when an inline comment STAYS
+
+If the body contains a comment that documents a real local WHY —
+something the function-level docstring cannot reasonably hold — keep it.
+
+```cpp
+// Workaround for boost #12345: pass nullptr instead of the empty buffer.
+boost::asio::buffer(nullptr, 0);
+
+// We deliberately do not lock here: the caller is required to hold
+// lock_ across this method and the recursion would deadlock.
+internalUpdate();
+```
+
+These are non-removable. They are not restating the code; they are
+explaining something the reader cannot derive from the line.
+
+## Rules that apply throughout
+
+- Do NOT modify code logic — only adjust comments and Doxygen.
+- Do NOT document entities that don't need it (private members with
+  obvious purpose, trivial defaulted constructors, getters whose name is
+  self-explanatory).
+- Do NOT read the primary's `.ai.md` file yourself — it is already in
+  your prompt as "Primary's Authoritative AI Context."
+- The partner's `.ai.md` (if any) is also already in your prompt as
+  "Partner's Authoritative AI Context." Use it to understand what
+  concepts the project assigns to the partner file, so you don't
+  duplicate them on the primary.
+- The "Primary's Authoritative AI Context" is the source of truth for
+  this file's intent. Your task is to translate that prose into Doxygen
+  on the actual declarations in the primary file, in the layer
+  (header vs. source) where each concept correctly belongs.
+- **Only modify the primary file.** Use Read (not Edit) on the partner
+  file — it is reference context, not an editing target.
+
+When you finish, summarize:
+- How many entities you documented
+- Any entities you skipped and why
+- Any code patterns you discovered that should be added to a skill file

+You are updating a per-module skill file for the xrpld codebase.
+
+A "skill" is a single markdown file at `docs/skills/<module>.md` that
+captures the institutional knowledge for one module: what it does, key
+classes, conventions, gotchas, and how to work in it. The skill file is
+loaded as context whenever an agent works on code in that module.
+
+## Inputs
+
+You will be given:
+- The current skill file for the module (the baseline to update)
+- A list of `.ai.md` files describing the source files in this module
+  (one per source file, with high-signal prose about purpose and design)
+
+## Your task
+
+Produce a new, improved skill file that integrates the knowledge from the
+ai.md files into the existing skill. Specifically:
+
+1. Update the description of the module's responsibility if the ai.md files
+   reveal more accurate or detailed framing
+2. Add any classes, patterns, or invariants the skill is missing
+3. Update lists of key files / entry points / conventions
+4. Add gotchas and non-obvious behavior surfaced by the ai.md files
+5. Keep the structure of the existing skill (don't reorganize for the sake
+   of it — only restructure if the existing structure is genuinely failing)
+6. Be terse. A skill file is a reference card, not a textbook. 200-500 lines
+   is typical; over 1000 means you're padding.
+
+## Quality rules
+
+- **Do not duplicate the ai.md content.** Aggregate, synthesize, distill.
+  The skill is the module-level view; individual file details belong in
+  ai.md (and eventually in inline Doxygen comments).
+- **Preserve accurate existing content.** Don't rewrite working sections.
+- **Cite file paths** for specific claims (e.g., "see `STAmount.h:roundToScale`").
+- **Flag contradictions.** If two ai.md files describe the same concept
+  differently, surface the conflict rather than silently picking one.
+- **Keep prose grounded.** No marketing language. No "robust, scalable,
+  enterprise-grade" filler. Engineers reading this need facts.
+
+## Output — Chunked Writing (REQUIRED)
+
+You have a per-turn output cap (32K tokens). For larger modules, a
+complete skill file will not fit in a single tool call. You MUST write
+the file in chunks across multiple tool calls. Do not try to emit the
+whole file in one Write — it will be truncated mid-content.
+
+Process:
+1. **First chunk (Write)**: Call the `Write` tool with the start of the
+   skill: the title heading, the opening overview, and the first 1–2
+   major sections. Keep this chunk under ~20K characters of content.
+2. **Subsequent chunks (Edit)**: For each remaining section, call the
+   `Edit` tool with:
+   - `old_string` = the last line currently at the end of the file (must
+     be unique enough to match unambiguously — use the full last line)
+   - `new_string` = that same last line **plus the next 1–2 sections**
+   appended
+   Keep each chunk under ~20K characters.
+3. **Repeat** until the skill is complete. There is no maximum number
+   of Edit calls.
+
+After the file is fully written, respond with a one-line confirmation
+listing how many chunks you wrote.
+
+DO NOT emit the skill content in your text response. The file is the
+output; the text response is only for confirmation.

+You are reviewing a pull request to the xrpld (XRP Ledger daemon) codebase
+for documentation drift.
+
+Your job: given a git diff, determine whether the changes invalidate
+existing Doxygen documentation comments, or introduce new public API
+surface that lacks documentation.
+
+## Rules
+
+- Only flag REAL semantic drift: changed behavior, new parameters, removed
+  functionality, changed return values, new error conditions, changed
+  invariants.
+- Do NOT flag cosmetic changes (whitespace, formatting, internal renames
+  that don't change semantics).
+- Do NOT suggest docs for private implementation details unless the logic

+- Do NOT paraphrase function signatures. Good docs explain WHY and what
+  BEHAVIOR — not what the code literally does.
+- Be terse: 1-3 sentences per finding.
+
+## Process
+
+1. For each changed file, get the git diff and the current file content
+2. Read existing doc comments on the modified entities
+3. For each modified entity, ask:
+   - Did behavior change in a way the docs miss?
+   - Did parameters or return values change?
+   - Are there new error conditions?
+   - Did the contract / invariant change?
+   - Is this a NEW public API surface with no docs?
+4. Read the module's skill file in `docs/skills/soul/` for context
+5. Read related tests if it helps you understand the change
+6. Output findings as structured JSON (see below)

+- `severity: warning` = doc is now incorrect / misleading
+- `severity: suggestion` = new code lacks docs, would be nice to add

 For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
 
-The API version controls the API behavior you see. This includes what properties you see in responses, what parameters you're permitted to send in requests, and so on. You specify the API version in each of your requests. When a breaking change is introduced to the `rippled` API, a new version is released. To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.

To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.
 
 The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
 
-For a log of breaking changes, see the **API Version [number]** headings. In general, breaking changes are associated with a particular API Version number. For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`rippled`) release.

+- Peer Crawler: The `port` field in `overlay.active[]` now consistently returns an integer instead of a string for outbound peers. [#6318](https://github.com/XRPLF/rippled/pull/6318)
+- `ping`: The `ip` field is no longer returned as an empty string for proxied connections without a forwarded-for header. It is now omitted, consistent with the behavior for identified connections. [#6730](https://github.com/XRPLF/rippled/pull/6730)

 ### Running clang-tidy locally
 
 Before running clang-tidy, you must build the project to generate required files (particularly protobuf headers). Refer to [`BUILD.md`](./BUILD.md) for build instructions.
 
+#### Via pre-commit (recommended)
+
+If you have already installed the pre-commit hooks (see above), you can run clang-tidy on your staged files using:
+
+```
+TIDY=1 pre-commit run clang-tidy
+```
+
+This runs clang-tidy locally with the same configuration/flags as CI, scoped to your staged C++ files. The `TIDY=1` environment variable is required to opt in — without it the hook is skipped.
+
+You can also have clang-tidy run automatically on every `git commit` by setting `TIDY=1` in your shell environment:
+
+```
+export TIDY=1
+```
+
+With this set, the hook will run as part of `git commit` alongside the other pre-commit checks.
+
+#### Manually
+
 Then run clang-tidy on your local changes:
 
 ```
-run-clang-tidy -p build src tests
+run-clang-tidy -p build -allow-no-checks src tests
 ```
 
-This will check all source files in the `src` and `tests` directories using the compile commands from your `build` directory.

+# XRPLD Automated Documentation System — Scope of Work
+
+## 1. Problem Statement
+
+The XRP Ledger daemon (`xrpld`) is a ~275,000 line C++ codebase with 1,183
+source files across the core library, protocol layer, and application server.
+It is the single implementation of the XRP Ledger protocol and processes
+billions of dollars in value.
+
+Despite this criticality, the codebase has minimal inline documentation. Only
+569 of 1,183 files contain any Doxygen-style doc comments, and most of those
+are sparse — a class-level sentence or two, rarely covering individual methods,
+parameters, or behavioral invariants.
+
+The only formal documentation effort — an external specification by Common
+Prefix — has fundamental structural problems:
+
+- **Drift is the default state.** The spec lives in a separate repository
+  with no CI linkage to the codebase. Every commit to `rippled` that changes
+  behavior silently invalidates the spec. Even one week of drift makes
+  the spec unreliable.
+- **Separate repo, separate context.** No contributor has both repos open.
+  When a bug comes in, the developer reads the code, not the spec. A
+  recent bug would have been caught if the code itself was documented.
+- **No code-level documentation.** The spec describes system-level behavior
+  (payment engine, DEX) but does not document individual functions, classes,
+  parameters, or invariants. A developer working on a specific function
+  gets no help.
+- **Vendor dependency.** Ripple has a critical documentation dependency on a
+  single external firm. If the contract ends, the spec orphans.
+- **Perverse incentive.** The vendor profits from complexity and drift.
+  Cleaner code and better inline docs reduce the need for external
+  specification work.
+
+## 2. Solution as Built
+
+An automated, in-repo documentation system with five components, all living
+alongside the code with no external repos and no external vendor dependency:
+
+1. **Module skills** — Per-module knowledge files in [docs/skills/](docs/skills/)
+   that capture the "soul" of each subsystem (key files, patterns, pitfalls,
+   invariants). These are the durable, human-maintained context that the
+   automated agent and human contributors both consult.
+2. **doc-agent (Claude Agent SDK app)** — A TypeScript tool at
+   [.github/scripts/doc-agent/](.github/scripts/doc-agent/) with three modes:
+   `document` (write Doxygen comments), `review` (detect drift on a diff),
+   and `regen-skills` (rebuild a skill file from current code).
+3. **Doc-review GitHub Action** — Runs the review mode on every PR; posts
+   inline comments and a sticky summary. Currently warning-only.
+4. **Coverage enforcement** — CI-enforced documentation coverage thresholds
+   that ratchet up over time, preventing regression.
+5. **Developer slash commands** — Claude Code commands in
+   [.claude/commands/](.claude/commands/) for onboarding, architecture
+   questions, doc review, and bug pattern detection.
+
+Documentation accuracy is enforced by CI the same way code style and test
+coverage are enforced today.
+
+## 3. Deliverables — Built
+
+### 3.1 Documentation Standards
+
+[docs/DOCUMENTATION_STANDARDS.md](docs/DOCUMENTATION_STANDARDS.md) — canonical
+format guide defining:
+- Javadoc-style `/** ... */` Doxygen comments (matches existing convention)
+- Documentation levels: file, class, public method, free function, enum
+- Required Doxygen tags: `@param`, `@return`, `@note`, `@invariant`
+- Quality rules: document behavior and invariants, never paraphrase
+  signatures, terse style (2–5 lines for classes, 1–3 for functions)
+
+### 3.2 Doxygen Configuration Changes
+
+[docs/Doxyfile](docs/Doxyfile):
+- `EXTRACT_ALL = NO` (was `YES`) — undocumented entities are flagged rather
+  than silently extracted
+- `GENERATE_XML = YES` (was `NO`) — required for coverxygen to parse and
+  measure documentation coverage
+
+### 3.3 Module Skills
+
+Thirteen module-level skill files in [docs/skills/](docs/skills/), each one
+a self-contained guide to a subsystem's responsibilities, key types, control
+flow, conventions, and common pitfalls:
+
+| Skill | Covers |
+|-------|--------|
+| [consensus.md](docs/skills/consensus.md) | XRPL consensus algorithm + RCL adapters |
+| [cryptography.md](docs/skills/cryptography.md) | CSPRNG, secure erasure, key handling |
+| [ledger.md](docs/skills/ledger.md) | ReadView/ApplyView, state tables, sandbox |
+| [nodestore.md](docs/skills/nodestore.md) | RocksDB/NuDB/Memory backends |
+| [peering.md](docs/skills/peering.md) | Overlay + peerfinder |
+| [protocol.md](docs/skills/protocol.md) | STObject, SField, Serializer, TER, Keylets |
+| [rpc.md](docs/skills/rpc.md) | RPC handler conventions |
+| [shamap.md](docs/skills/shamap.md) | SHA-256 Merkle radix tree |
+| [sql.md](docs/skills/sql.md) | SOCI database wrapper, checkpointing |
+| [test.md](docs/skills/test.md) | Beast unit test framework conventions |
+| [transactors.md](docs/skills/transactors.md) | Full transactor template |
+| [websockets.md](docs/skills/websockets.md) | WS subscriptions/streams |
+| [index.md](docs/skills/index.md) | Top-level codebase map |
+
+These skills serve a dual purpose: they are reference docs for human
+contributors, and they are injected as system-prompt context by the
+doc-agent (mapping in [src/config.ts](.github/scripts/doc-agent/src/config.ts)).
+
+[install-skills.sh](.github/scripts/doc-agent/install-skills.sh) installs
+the same files as Claude Code skills under `.claude/skills/<name>/SKILL.md`,
+so any Claude Code session in the repo picks them up automatically.
+
+### 3.4 doc-agent (Claude Agent SDK)
+
+A TypeScript application at [.github/scripts/doc-agent/](.github/scripts/doc-agent/),
+built on `@anthropic-ai/claude-agent-sdk`. Three modes:
+
+| Mode | Purpose |
+|------|---------|
+| `document` | Add Doxygen comments to a file or directory. Reads sibling `<file>.ai.md` context, the module skill, and the source file; uses `permissionMode: 'acceptEdits'` to write directly. |
+| `review` | Given a git range or PR number, detect doc drift. Emits `doc-review-report.md` (sticky comment) and `doc-review-comments.json` (inline comments). |
+| `regen-skills` | Rebuild a module's skill file at `docs/skills/<module>.md` from the module's `.ai.md` files plus existing skill content. |
+
+Layout:
+
+```
+doc-agent/
+├── package.json          # Node >= 20.12, @anthropic-ai/claude-agent-sdk
+├── biome.json            # lint + format
+├── install-skills.sh     # copies docs/skills/*.md → .claude/skills/*/SKILL.md
+├── prompts/              # System prompts as markdown (editable without code changes)
+│   ├── document-file.md
+│   ├── review-diff.md
+│   └── regen-skill.md
+└── src/
+    ├── index.ts          # CLI entry (document | review | regen-skills)
+    ├── config.ts         # Paths, model, MODULE_SKILL_MAP
+    ├── prompt-loader.ts  # Loads prompts + injects module skill
+    ├── document.ts
+    ├── review.ts
+    ├── regen-skills.ts
+    └── types.ts
+```
+
+Notable design decisions:
+- **Prompts as markdown, not strings.** Operators tune prompts without
+  touching TypeScript or redeploying.
+- **`.ai.md` sidecar input.** When documenting a file, the agent reads a
+  sibling `<file>.ai.md` (high-signal prose generated upstream by the
+  `athenah-ai` pipeline) as the authoritative source of intent. These are
+  gitignored (`*.ai.md` in [.gitignore](.gitignore)) and discarded once
+  the initial pass is complete.
+- **Model selection via env.** `DOC_AGENT_MODEL` env var; default
+  `claude-sonnet-4-6`.
+- **Repo root override.** `XRPLD_ROOT` env var allows running the agent
+  against a different checkout (useful in CI and local testing).
+
+### 3.5 Documentation Coverage Pipeline
+
+| File | Purpose |
+|------|---------|
+| [.github/doc-coverage-thresholds.json](.github/doc-coverage-thresholds.json) | Per-module thresholds + quarterly ratchet schedule |
+| [.github/scripts/doc-coverage-check.py](.github/scripts/doc-coverage-check.py) | Parses coverxygen LCOV, checks thresholds, generates PR report |
+| [.github/workflows/doc-coverage.yml](.github/workflows/doc-coverage.yml) | CI workflow: builds Doxygen XML, runs coverxygen, posts coverage to PR |
+| [cmake/XrplDocs.cmake](cmake/XrplDocs.cmake) | `docs` CMake target wiring |
+
+Flow:
+1. On every PR touching C++ files, the workflow builds Doxygen XML for
+   both the PR branch and the base branch (using
+   `ghcr.io/xrplf/ci/tools-rippled-documentation`).
+2. Coverxygen generates LCOV-format coverage from the XML.
+3. The check script compares coverage against per-module thresholds.
+4. Ratchet mode (`no_decrease`) prevents any PR from reducing coverage.
+5. New files added in a PR require ≥ 80% doc coverage.
+6. Results are posted as a sticky PR comment with per-module breakdown.
+
+### 3.6 Doc-Review GitHub Action
+
+| File | Purpose |
+|------|---------|
+| [.github/workflows/doc-review.yml](.github/workflows/doc-review.yml) | CI workflow: runs on PR, posts review |
+
+The workflow invokes the doc-agent `review` mode (Section 3.4) directly —
+there is no separate CI script. The same code path serves CI and local use,
+so prompt and logic changes are tested in one place.
+
+Flow:
+1. On every PR, the workflow runs `npm run review -- "$BASE..$HEAD"` in the
+   doc-agent directory.
+2. doc-agent enumerates C++ files changed in the range, extracts diff
+   hunks plus existing doc comments, and asks Claude per file whether the
+   docs are still accurate.
+3. Outputs `doc-review-report.md` (sticky PR comment) and
+   `doc-review-comments.json` (inline review comments via
+   `actions/github-script`).
+4. Runs in **warning-only mode** — does not block merge.
+
+Local invocation uses the same command:
+`npm run review develop..HEAD` or `npm run review -- --pr 1234`.
+
+Cost: only changed files and changed hunks within those files are
+processed. Estimated ~$0.05–0.15 per PR.
+
+### 3.7 Claude Code Slash Commands
+
+Four developer-facing commands in [.claude/commands/](.claude/commands/):
+
+| Command | Purpose |
+|---------|---------|
+| [doc-review](.claude/commands/doc-review.md) | Review doc accuracy for files changed on current branch |
+| [explain-module](.claude/commands/explain-module.md) | Explain a module's architecture, classes, control flow, entry points |
+| [how-does-x-work](.claude/commands/how-does-x-work.md) | Trace a feature through the codebase with file/line references |
+| [find-bug-patterns](.claude/commands/find-bug-patterns.md) | Scan code for common xrpld bug patterns (unchecked TER, integer overflow, missing amendment gates, etc.) |
+
+### 3.8 Full Codebase Documentation
+
+The initial documentation pass covers 1,183 C++ files organized into 21
+module-level PRs (see Section 5). The doc-agent `document` mode produces
+each PR in parallel across modules; each file's output is then
+domain-expert reviewed before merge.
+
+## 4. Resources Required
+
+### 4.1 People
+
+| Role | Responsibility |
+|------|---------------|
+| **Documentation lead** | Runs `doc-agent document` per module, reviews output, submits PRs, iterates on prompts in [prompts/](.github/scripts/doc-agent/prompts/) |
+| **Domain reviewers** (rotating) | Review doc PRs for semantic accuracy in their area of expertise |
+| **CI/infrastructure** | Deploys workflows, monitors costs, tunes false-positive rate on doc-review action |
+
+### 4.2 Infrastructure & Tools
+
+| Resource | Purpose |
+|----------|---------|
+| **Anthropic API access** | Powers the doc-agent (`document`, `review`, `regen-skills`) and the doc-review GitHub Action |
+| **Claude Agent SDK** | `@anthropic-ai/claude-agent-sdk` Node package |
+| **Node.js >= 20.12** | Native `--env-file` support; runs the doc-agent |
+| **GitHub Actions minutes** | Doc-coverage workflow (Doxygen XML build + coverxygen) and doc-review workflow |
+| **Coverxygen** | Python package, open source (MIT) |
+| **Doxygen** | Already configured — uses existing `ghcr.io/xrplf/ci/tools-rippled-documentation` container |
+| **GitHub Actions secret** | `ANTHROPIC_API_KEY` — for doc-review workflow |
+| **athenah-ai pipeline output** | Generates `.ai.md` sidecar context files consumed by `doc-agent document`; gitignored, removed post-pass |
+
+### 4.3 Access & Permissions
+
+- Write access to the `rippled` repository (or a fork for initial PRs)
+- Ability to add GitHub Actions secrets (`ANTHROPIC_API_KEY`)
+- Ability to modify required status checks (when promoting doc-review from
+  warning to required)
+
+## 5. Execution Plan
+
+Module passes run in parallel — the doc-agent operates per-module
+independently, so foundation, protocol, and application layers are
+generated concurrently rather than sequentially. Module groupings below
+reflect dependency layering for review purposes, not a serial schedule.
+
+### Phase 0: Infrastructure — Complete
+
+Tooling shipped as the foundation PR:
+
+- [x] [docs/DOCUMENTATION_STANDARDS.md](docs/DOCUMENTATION_STANDARDS.md)
+- [x] [docs/Doxyfile](docs/Doxyfile) modifications
+- [x] [docs/skills/](docs/skills/) — 13 module skills + index
+- [x] [.github/scripts/doc-agent/](.github/scripts/doc-agent/) — Agent SDK app (document / review / regen-skills)
+- [x] [.github/scripts/doc-agent/install-skills.sh](.github/scripts/doc-agent/install-skills.sh)
+- [x] [.github/doc-coverage-thresholds.json](.github/doc-coverage-thresholds.json)
+- [x] [.github/scripts/doc-coverage-check.py](.github/scripts/doc-coverage-check.py)
+- [x] [.github/workflows/doc-coverage.yml](.github/workflows/doc-coverage.yml)
+- [x] [cmake/XrplDocs.cmake](cmake/XrplDocs.cmake)
+- [x] [.github/workflows/doc-review.yml](.github/workflows/doc-review.yml) — invokes doc-agent `review` mode directly
+- [x] [.claude/commands/](.claude/commands/) — 4 developer slash commands
+
+**Exit criteria met:** All workflows pass on a test PR. Coverage report
+renders correctly. Doc-review action posts comments without false positives
+on a sample PR.
+
+### Phase 1: Foundation Modules
+
+Lowest-level modules — everything else depends on these:
+
+| PR | Module | ~Files | ~Lines |
+|----|--------|--------|--------|
+| 1 | `include/xrpl/basics/` + `src/libxrpl/basics/` | 63 | ~15K |
+| 2 | `include/xrpl/crypto/` + `src/libxrpl/crypto/` | 6 | ~1.5K |
+| 3 | `include/xrpl/json/` + `src/libxrpl/json/` | 18 | ~4K |
+| 4 | `include/xrpl/beast/` + `src/libxrpl/beast/` | 88 | ~20K |
+
+**Process per PR:**
+1. Create branch `docs/module-<name>` from `develop`.
+2. Run `npm run document <path>` from `.github/scripts/doc-agent/`. The
+   agent reads each file's `.ai.md` sidecar, the matching module skill,
+   and the file itself, then writes Doxygen comments per the standards.
+3. Domain expert reviews for semantic accuracy.
+4. Run Doxygen build to validate no doc errors.
+5. Merge; ratchet that module's threshold up to actual coverage level.
+
+### Phase 2: Protocol & Transaction Engine
+
+| PR | Module | ~Files |
+|----|--------|--------|
+| 5 | `include/xrpl/protocol/` + `src/libxrpl/protocol/` | 150 |
+| 6 | `include/xrpl/ledger/` + `src/libxrpl/ledger/` | 68 |
+| 7 | `include/xrpl/conditions/` + `src/libxrpl/conditions/` | 8 |
+| 8 | `include/xrpl/tx/` (core framework: Transactor, ApplyContext) | 15 |
+| 9 | Payment transactors | 9 |
+| 10 | DEX/AMM transactors | 25 |
+| 11 | Escrow transactors | 7 |
+| 12 | Other transactors (NFT, token, vault, check, etc.) | 60 |
+| 13 | Pathfinding + invariants | 30 |
+
+### Phase 3: Server & Application Layer
+
+| PR | Module | ~Files |
+|----|--------|--------|
+| 14 | `include/xrpl/server/` + `src/libxrpl/server/` | 35 |
+| 15 | `include/xrpl/nodestore/` + `src/libxrpl/nodestore/` | 30 |
+| 16 | SHAMap | 25 |
+| 17 | Resource management | 17 |
+| 18 | Overlay + peerfinder | 56 |
+| 19 | Consensus | 15 |
+| 20 | Application core (ledger, main, misc, rdb) | 133 |
+| 21 | RPC handlers | 131 |
+
+Once Phases 1–3 are merged, the doc-review action is promoted from
+warning to a **required check**.
+
+### Phase 4: Tests & Polish
+
+- Document test files (brief docs only — test name + what it validates)
+- Remove `.ai.md` sidecar files (they were transitional input only)
+- Retrospective: false-positive rate, API costs, contributor feedback
+
+## 6. Coverage Threshold Ratchet
+
+Coverage thresholds are enforced per-module via
+[.github/doc-coverage-thresholds.json](.github/doc-coverage-thresholds.json):
+
+- **`no_decrease` ratchet** — no PR may reduce coverage on a module
+  below its current level.
+- **New files** require ≥ 80% doc coverage regardless of module threshold.
+- **Per-module floors** are raised manually as each module's PR lands,
+  pinning the achieved coverage as the new floor.
+
+There is no calendar-based ratchet; thresholds advance with the work.
+
+## 7. Risk Assessment
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| LLM generates plausible but wrong docs | Medium | High | Every doc PR requires human domain expert review. `.ai.md` sidecars (athenah-ai) ground the agent in source-derived intent rather than free generation. |
+| Doc-review action false positives annoy contributors | Medium | Medium | Warning-only mode initially. Promote to required only when FP rate < 5%. Prompts live in markdown ([prompts/](.github/scripts/doc-agent/prompts/)) and can be tuned without a code release. |
+| Coverage enforcement blocks unrelated PRs | Low | Medium | `no_decrease` ratchet only; per-module floors raised manually as modules land. |
+| Reviewer bandwidth bottleneck | Medium | Medium | PRs scoped to single modules. Reviewers rotate. |
+| API costs exceed budget | Low | Low | Only diff hunks processed. Monthly budget cap with alerting. |
+| Doxygen XML build adds CI time | Low | Low | Runs in parallel with existing checks. Uses existing documentation container. |
+| Doc comments add code noise | Low | Low | Terse style enforced by standards. 2–5 lines per class, 1–3 per function. |
+| Skill files drift from code | Medium | Medium | `doc-agent regen-skills <module>` rebuilds a skill from current `.ai.md` files; intended to be run periodically. |
+
+## 8. Success Metrics
+
+| Metric | Measurement |
+|--------|-------------|
+| Documentation coverage (public API) | Coverxygen LCOV reports in CI |
+| Doc drift catch rate | Sample audit of merged PRs vs doc-review output |
+| False positive rate (doc-review action) | Track dismissed vs accepted suggestions |
+| Spec-vs-code contradictions | Bug reports citing wrong documentation |
+| Contributor satisfaction | Periodic survey: "docs helped me understand the code" |
+| Onboarding time | Measure across new contributors before/after |
+| API cost | Anthropic API billing dashboard |
+
+## 9. What This Replaces
+
+This system does **not** replace the Common Prefix formal verification
+work directly — formal verification and code documentation solve different
+problems. However, it eliminates the need for an external specification as
+the "source of truth" for how xrpld behaves:
+
+| Need | Before | After |
+|------|--------|-------|
+| "What does this function do?" | Read the code, guess | Read the inline Doxygen doc |
+| "How does the payment engine work?" | Read Common Prefix spec (maybe stale) | Read [docs/skills/transactors.md](docs/skills/transactors.md) or run `/explain-module` |
+| "Did this PR break any documented behavior?" | Manual review, hope someone notices | Doc-review action flags it automatically |
+| "What's our documentation coverage?" | Unknown | Measured per-module in every PR |
+| "Is the spec up to date?" | Check manually, probably not | Docs are in-repo, enforced by CI |
+| "Where do I start in module X?" | Ask in chat | Read the module skill in [docs/skills/](docs/skills/) |
+
+## 10. Out of Scope
+
+- **Formal verification.** This project documents code behavior; it does
+  not prove correctness. Formal verification is a separate discipline.
+- **External-facing API documentation.** This covers the C++ source code,
+  not the JSON-RPC API documentation on xrpl.org.
+- **Test coverage.** Test file documentation is brief and optional. Test
+  coverage measurement is handled by existing Codecov integration.
+- **Architectural decision records.** Module-level READMEs already exist
+  for key subsystems. This project adds function/class-level docs and the
+  module skills layer, not system-level ADRs.

+This program allows us to recognize and reward individuals or groups that identify and report bugs.
 
-1. **In scope**. Only bugs in software under the scope of the program qualify. Currently, that means `rippled`, `xrpl.js`, `xrpl-py`, `xrpl4j`.
-2. **Relevant**. A security issue, posing a danger to user funds, privacy, or the operation of the XRP Ledger.
-3. **Original and previously unknown**. Bugs that are already known and discussed in public do not qualify. Previously reported bugs, even if publicly unknown, are not eligible.
-4. **Specific**. We welcome general security advice or recommendations, but we cannot pay bounties for that.
-5. **Fixable**. There has to be something we can do to permanently fix the problem. Note that bugs in other people’s software may still qualify in some cases. For example, if you find a bug in a library that we use which can compromise the security of software that is in scope and we can get it fixed, you may qualify for a bounty.
-6. **Unused**. If you use the exploit to attack the XRP Ledger, you do not qualify for a bounty. If you report a vulnerability used in an ongoing or past attack and there is specific, concrete evidence that suggests you are the attacker we reserve the right not to pay a bounty.
-
-The amount paid varies dramatically. Vulnerabilities that are harmless on their own, but could form part of a critical exploit will usually receive a bounty. Full-blown exploits can receive much higher bounties. Please don’t hold back partial vulnerabilities while trying to construct a full-blown exploit. We will pay a bounty to anyone who reports a complete chain of vulnerabilities even if they have reported each component of the exploit separately and those vulnerabilities have been fixed in the meantime. However, to qualify for a the full bounty, you must to have been the first to report each of the partial exploits.

-   Configure sanitizers based on environment variables.
+   Apply sanitizer flags built by the Conan profile.
 
-   This module reads the following environment variables:
-   - SANITIZERS: The sanitizers to enable. Possible values:
-     - "address"
-     - "address,undefinedbehavior"
-     - "thread"
-     - "thread,undefinedbehavior"
-     - "undefinedbehavior"
+   Parsing, validation, and flag construction are performed in conan/profiles/sanitizers.
+   This module reads the following CMake variables injected by the Conan toolchain via extra_variables:
 
-   The compiler type and platform are detected in CompilationEnv.cmake.
-   The sanitizer compile options are applied to the 'common' interface library
-   which is linked to all targets in the project.
+   - SANITIZERS:                The active sanitizers (e.g. "address,undefinedbehavior").
+   - SANITIZERS_COMPILER_FLAGS: Space-separated compiler flags.
+   - SANITIZERS_LINKER_FLAGS:   Space-separated linker flags.
 
-   Internal flag variables set by this module:
-
-   - SANITIZER_TYPES: List of sanitizer types to enable (e.g., "address",
-     "thread", "undefined"). And two more flags for undefined behavior sanitizer (e.g., "float-divide-by-zero", "unsigned-integer-overflow").
-     This list is joined with commas and passed to -fsanitize=<list>.
-
-   - SANITIZERS_COMPILE_FLAGS: Compiler flags for sanitizer instrumentation.
-     Includes:
-     * -fno-omit-frame-pointer: Preserves frame pointers for stack traces
-     * -O1: Minimum optimization for reasonable performance
-     * -fsanitize=<types>: Enables sanitizer instrumentation
-     * -fsanitize-ignorelist=<path>: (Clang only) Compile-time ignorelist
-     * -mcmodel=large/medium: (GCC only) Code model for large binaries
-     * -Wno-stringop-overflow: (GCC only) Suppresses false positive warnings
-     * -Wno-tsan: (For GCC TSAN combination only) Suppresses atomic_thread_fence warnings
-
-   - SANITIZERS_LINK_FLAGS: Linker flags for sanitizer runtime libraries.
-     Includes:
-     * -fsanitize=<types>: Links sanitizer runtime libraries
-     * -mcmodel=large/medium: (GCC only) Matches compile-time code model
-
-   - SANITIZERS_RELOCATION_FLAGS: (GCC only) Code model flags for linking.
-     Used to handle large instrumented binaries on x86_64:
-     * -mcmodel=large: For AddressSanitizer (prevents relocation errors)
-     * -mcmodel=medium: For ThreadSanitizer (large model is incompatible)
+   The flags are applied to the 'common' interface library which is linked to all targets in the project.
