+Format embedded shell snippets using the shfmt hook configured in
+.pre-commit-config.yaml.
+
+Two shapes are recognised:
+
+* YAML workflow/action files: literal block-scalar runs (`run: |`) and
+  single-line runs (`run: some command`). A single-line run is upgraded to
+  a `run: |` block scalar if shfmt's output spans multiple lines.
+
+* Markdown files: ``` ```bash ``` fenced code blocks.
+
+Any block that shfmt cannot parse is skipped with a warning on stderr, so
+the file is left untouched and surrounding blocks still get formatted.
+
+For each occurrence the body is dedented, written to a temp .sh file,
+formatted via `pre-commit run shfmt --files <temp>` (falling back to
+`prek`), then re-indented and written back in place.
+
+When invoked without arguments, every .yml/.yaml under .github/ plus every
+.md file in the repo is scanned. When invoked with file arguments (the
+pre-commit case), only those files are processed.

-### Responsible Disclosure
-
-If you discover a vulnerability or potential threat, or if you _think_
-you have, please reach out by dropping an email using the contact
-information below.
-
-Your report should include the following:
-
-- Your contact information (typically, an email address);
-- The description of the vulnerability;
-- The attack scenario (if any);
-- The steps to reproduce the vulnerability;
-- Any other relevant details or artifacts, including code, scripts or patches.

-In your email, please describe the issue or potential threat. If possible, include a "repro" (code that can reproduce the issue) or describe the best way to reproduce and replicate the issue. Please make your report as detailed and comprehensive as possible.

-
-## Report Handling Process
-
-Please report the bug directly to us and limit further disclosure. If you want to prove that you knew the bug as of a given time, consider using a cryptographic pre-commitment: hash the content of your report and publish the hash on a medium of your choice (e.g. on Twitter or as a memo in a transaction) as "proof" that you had written the text at a given point in time.
-
-Once we receive a report, we:
-
-1. Assign two people to independently evaluate the report;
-2. Consider their recommendations;
-3. If action is necessary, formulate a plan to address the issue;
-4. Communicate privately with the reporter to explain our plan.
-5. Prepare, test and release a version which fixes the issue; and
-6. Announce the vulnerability publicly.
-
-We will triage and respond to your disclosure within 24 hours. Beyond that, we will work to analyze the issue in more detail, formulate, develop and test a fix.
-
-While we commit to responding with 24 hours of your initial report with our triage assessment, we cannot guarantee a response time for the remaining steps. We will communicate with you throughout this process, letting you know where we are and keeping you updated on the timeframe.

+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 `xrpld`, `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)

 **Why `detect_container_overflow=0`?**
 
-- Boost intrusive containers (used in `aged_unordered_container`) trigger false positives
+- Boost intrusive containers (used in `AgedUnorderedContainer`) trigger false positives
 - Boost context switching (used in `Workers.cpp`) confuses ASAN's stack tracking
 - Since we usually don't build Boost (because we don't want to instrument Boost and detect issues in Boost code) with ASAN but use Boost containers in ASAN instrumented xrpld code, it generates false positives.
 - Building dependencies with ASAN instrumentation reduces false positives. But we don't want to instrument dependencies like Boost with ASAN because it is slow (to compile as well as run tests) and not necessary.
