+(In the following, use `sysctl -n hw.logicalcpu` instead of `nproc` on macOS)
+
+To build Lean you should use `make -j$(nproc) -C build/release`.
+
+## Running Tests
+
+See `tests/README.md` for full documentation. Quick reference:
+
+```bash
+# Full test suite (use after builds to verify correctness)
+CTEST_PARALLEL_LEVEL="$(nproc)" CTEST_OUTPUT_ON_FAILURE=1 \
+make -C build/release -j "$(nproc)" test
+
+# Specific test by name (supports regex via ctest -R)
+CTEST_PARALLEL_LEVEL="$(nproc)" CTEST_OUTPUT_ON_FAILURE=1 \
+make -C build/release -j "$(nproc)" test ARGS='-R grind_ematch'
+
+# Rerun only previously failed tests
+CTEST_PARALLEL_LEVEL="$(nproc)" CTEST_OUTPUT_ON_FAILURE=1 \
+make -C build/release -j "$(nproc)" test ARGS='--rerun-failed'
+
+# Single test from tests/foo/bar/ (quick check during development)
+CTEST_PARALLEL_LEVEL="$(nproc)" CTEST_OUTPUT_ON_FAILURE=1 \
+make -C build/release -j "$(nproc)" test ARGS=-R testname'
+```
+
+## Testing stage 2
+
+When requested to test stage 2, build it as follows:
+```
+make -C build/release stage2 -j$(nproc)
+```
+Stage 2 is *not* automatically invalidated by changes to `src/` which allows for faster iteration
+when fixing a specific file in the stage 2 build but for invalidating any files that already passed
+the stage 2 build as well as for final validation,
+```
+make -C build/release/stage2 clean-stdlib
+```
+must be run manually before building.
+
+## New features
+
+When asked to implement new features:
+* begin by reviewing existing relevant code and tests
+* write comprehensive tests first (expecting that these will initially fail)
+* and then iterate on the implementation until the tests pass.
+
+## Success Criteria
+
+*Never* report success on a task unless you have verified both a clean build without errors, and that the relevant tests pass.
+
+## Build System Safety
+
+**NEVER manually delete build directories** (build/, stage0/, stage1/, etc.) even when builds fail.
+- ONLY use the project's documented build command: `make -j$(nproc) -C build/release`
+- If a build is broken, ask the user before attempting any manual cleanup
+
+## stage0 Is a Copy of src
+
+**Never manually edit files under `stage0/`.** The `stage0/` directory is a snapshot of `src/` produced by `make update-stage0`. To change anything in stage0 (CMakeLists.txt, C++ source, etc.), edit the corresponding file in `src/` and let `update-stage0` propagate it.
+
+## LSP and IDE Diagnostics
+
+After rebuilding, LSP diagnostics may be stale until the user interacts with files. Trust command-line test results over IDE diagnostics.
+
+## Update prompting when the user is frustrated
+
+If the user expresses frustration with you, stop and ask them to help update this `.claude/CLAUDE.md` file with missing guidance.
+
+## Creating pull requests
+
+Follow the commit convention in `doc/dev/commit_convention.md`.
+
+**Title format:** `<type>: <subject>` where type is one of: `feat`, `fix`, `doc`, `style`, `refactor`, `test`, `chore`, `perf`.
+Subject should use imperative present tense ("add" not "added"), no capitalization, no trailing period.
+
+**Body format:** The first paragraph must start with "This PR". This paragraph is automatically incorporated into release notes. Use imperative present tense. Include motivation and contrast with previous behavior when relevant. Do NOT use markdown headings (`## Summary`, `## Test plan`, etc.) in PR bodies.
+
+Example:
+```
+feat: add optional binder limit to `mkPatternFromTheorem`
+
+This PR adds a `num?` parameter to `mkPatternFromTheorem` to control how many
+leading quantifiers are stripped when creating a pattern.
+```
+
+**Changelog labels:** Add one `changelog-*` label to categorize the PR for release notes:
+- `changelog-language` - Language features and metaprograms
+- `changelog-tactics` - User facing tactics
+- `changelog-server` - Language server, widgets, and IDE extensions
+- `changelog-pp` - Pretty printing
+- `changelog-library` - Library
+- `changelog-compiler` - Compiler, runtime, and FFI
+- `changelog-lake` - Lake
+- `changelog-doc` - Documentation
+- `changelog-ffi` - FFI changes
+- `changelog-other` - Other changes
+- `changelog-no` - Do not include this PR in the release changelog
+
+If you're unsure which label applies, it's fine to omit the label and let reviewers add it.
+
+## Module System for `src/` Files
+
+Files in `src/Lean/`, `src/Std/`, and `src/lake/Lake/` must have both `module` and `prelude` (CI enforces `^prelude$` on its own line). With `prelude`, nothing is auto-imported — you must explicitly import `Init.*` modules for standard library features. Check existing files in the same directory for the pattern, e.g.:
+
+```lean
+module
+
+prelude
+import Init.While  -- needed for while/repeat
+import Init.Data.String.TakeDrop  -- needed for String.startsWith
+public import Lean.Compiler.NameMangling  -- public if types are used in public signatures
+```
+
+Files outside these directories (e.g. `tests/`, `script/`) use just `module`.
+
+## CI Log Retrieval
+
+When CI jobs fail, investigate immediately - don't wait for other jobs to complete. Individual job logs are often available even while other jobs are still running. Try `gh run view <run-id> --log` or `gh run view <run-id> --log-failed`, or use `gh run view <run-id> --job=<job-id>` to target the specific failed job. Sleeping is fine when asked to monitor CI and no failures exist yet, but once any job fails, investigate that failure immediately.
+
+## Copyright Headers
+
+New files require a copyright header. To get the year right, always run `date +%Y` rather than relying on memory. The copyright holder should be the author or their current employer — check other recent files by the same author in the repository to determine the correct entity (e.g., "Lean FRO, LLC", "Amazon.com, Inc. or its affiliates").
+
+Test files (in `tests/`) do not need copyright headers.

+# Release Management Command
+
+Execute the release process for a given version by running the release checklist and following its instructions.
+
+## Before Starting
+
+**IMPORTANT**: Before beginning the release process, read the in-file documentation:
+- Read `script/release_checklist.py` for what the checklist script does
+- Read `script/release_steps.py` for what the release steps script does
+
+These comments explain the scripts' behavior, which repositories get special handling, and how errors are handled.
+
+## Arguments
+- `version`: The version to release (e.g., v4.24.0)
+
+## Release Notes (Required for -rc1 releases)
+
+For first release candidates (`-rc1`), you must create release notes BEFORE the reference-manual toolchain bump PR can be merged.
+
+**Steps to create release notes:**
+
+1. Generate the release notes:
+   ```bash
+   cd /path/to/lean4
+   python3 script/release_notes.py --since <previous_version> > /tmp/release-notes-<version>.md
+   ```
+   Replace `<previous_version>` with the last stable release (e.g., `v4.27.0` when releasing `v4.28.0-rc1`).
+
+2. Review `/tmp/release-notes-<version>.md` for common issues:
+   - **Unterminated code blocks**: Look for code fences that aren't closed. Fetch original PR with `gh pr view <number>` to repair.
+   - **Truncated descriptions**: Some may end mid-sentence. Complete them from the original PR.
+   - **Markdown issues**: Other syntax problems that could cause parsing errors.
+
+3. Create the release notes file in the reference-manual repository:
+   - File path: `Manual/Releases/v<version>.lean` (e.g., `v4_28_0.lean`)
+   - Use Verso format with proper imports and `#doc (Manual)` block
+   - **Use `#` for headers, not `##`** (Verso uses level 1 for subsections)
+   - **Use plain ` ``` ` not ` ```lean `** (the latter executes code)
+   - **Wrap underscore identifiers in backticks**: `` `bv_decide` `` not `bv_decide`
+
+4. Update `Manual/Releases.lean`:
+   - Add import: `import Manual.Releases.«v4_28_0»`
+   - Add include: `{include 0 Manual.Releases.«v4_28_0»}`
+
+5. Build to verify: `lake build Manual.Releases.v4_28_0`
+
+6. Create a **separate PR** for release notes (not bundled with toolchain bump):
+   ```bash
+   git checkout -b v<version>-release-notes
+   gh pr create --title "doc: add v<version> release notes"
+   ```
+
+For subsequent RCs (`-rc2`, etc.) and stable releases, just update the version number in the existing release notes file title.
+
+See `doc/dev/release_checklist.md` section "Writing the release notes" for full details.
+
+## Process
+
+1. Run `script/release_checklist.py {version}` to check the current status
+2. **CRITICAL: If preliminary lean4 checks fail, STOP immediately and alert the user**
+   - Check for: release branch exists, CMake version correct, tag exists, release page exists, release notes file exists
+   - **IMPORTANT**: The release page is created AUTOMATICALLY by CI after pushing the tag - DO NOT create it manually
+   - **IMPORTANT**: For -rc1 releases, release notes must be created before proceeding
+   - Do NOT create any PRs or proceed with repository updates if these checks fail
+3. Create a todo list tracking all repositories that need updates
+4. **CRITICAL RULE: You can ONLY run `release_steps.py` for a repository if `release_checklist.py` explicitly says to do so**
+   - The checklist output will say "Run `script/release_steps.py {version} {repo_name}` to create it"
+   - If a repository shows "🟡 Dependencies not ready", you CANNOT create a PR for it yet
+   - You MUST rerun `release_checklist.py` before attempting to create PRs for any new repositories
+5. For each repository that the checklist says needs updating:
+   - Run `script/release_steps.py {version} {repo_name}` to create the PR
+   - Mark it complete when the PR is created
+6. After creating PRs, notify the user which PRs need review and merging
+7. **MANDATORY: Rerun `release_checklist.py` to check current status**
+   - Do this after creating each batch of PRs
+   - Do this after the user reports PRs have been merged
+   - NEVER assume a repository is ready without checking the checklist output
+8. As PRs are merged and tagged, dependent repositories will become ready
+9. Continue the cycle: run checklist → create PRs for ready repos → wait for merges → repeat
+10. Continue until all repositories are updated and the release is complete
+
+## Important Notes
+
+- **NEVER merge PRs autonomously** - always wait for the user to merge PRs themselves
+- The `release_steps.py` script is idempotent - it's safe to rerun
+- The `release_checklist.py` script is idempotent - it's safe to rerun
+- Some repositories depend on others (e.g., mathlib4 depends on batteries, aesop, etc.)
+- Wait for user to merge PRs before dependent repos can be updated
+- Alert user if anything unusual or scary happens
+- Use appropriate timeouts for long-running builds (verso can take 10+ minutes)
+- ProofWidgets4 uses semantic versioning (v0.0.X) - it's okay to create and push the next sequential tag yourself when needed for a release
+
+## PR Status Reporting
+
+Every time you run `release_checklist.py`, you MUST:
+1. Parse the output to identify ALL open PRs mentioned (lines with "✅ PR with title ... exists")
+2. Provide a summary to the user listing ALL open PRs that need review
+3. Group them by status:
+   - PRs for repositories that are blocked by dependencies (show these but note they're blocked)
+   - PRs for repositories that are ready to merge (highlight these)
+4. Format the summary clearly with PR numbers and URLs
+
+This summary should be provided EVERY time you run the checklist, not just after creating new PRs.
+The user needs to see the complete picture of what's waiting for review.
+
+## Checking PR Status When Asked
+
+When the user asks for "status" or you need to report on PRs between checklist runs:
+- **ALWAYS check actual PR state** using `gh pr view <number> --repo <repo> --json state,mergedAt`
+- Do NOT rely on cached CI results or previous checklist output
+- The user may have merged PRs since your last check
+- Report which PRs are MERGED, which are OPEN with CI status, and which are still pending
+- After discovering merged PRs, rerun `release_checklist.py` to advance the release process
+
+## Nightly Infrastructure
+
+The nightly build system uses branches and tags across two repositories:
+
+- `leanprover/lean4` has **branches** `nightly` and `nightly-with-mathlib` tracking the latest nightly builds
+- `leanprover/lean4-nightly` has **dated tags** like `nightly-2026-01-23`
+
+When a nightly succeeds with mathlib, all three should point to the same commit. Don't confuse these: branches are in the main lean4 repo, dated tags are in lean4-nightly.
+
+## CI Failures: Investigate Immediately
+
+**CRITICAL: If the checklist reports `❌ CI: X check(s) failing` for any PR, investigate immediately.**
+
+Do NOT:
+- Report it as "CI in progress" or "some checks pending"
+- Wait for the remaining checks to finish before investigating
+- Assume it's a transient failure without checking
+
+DO:
+1. Run `gh pr checks <number> --repo <owner>/<repo>` to see which specific check failed
+2. Run `gh run view <run-id> --repo <owner>/<repo> --log-failed` to see the failure output
+3. Diagnose the failure and report clearly to the user: what failed and why
+4. Propose a fix if one is obvious (e.g., subverso version mismatch, transient elan install error)
+
+The checklist now distinguishes `❌ X check(s) failing, Y still in progress` from `🔄 Y check(s) in progress`.
+Any `❌` in CI status requires immediate investigation — do not move on.
+
+## Waiting for CI or Merges
+
+Use `gh pr checks --watch` to block until a PR's CI checks complete (no polling needed).
+Run these as background bash commands so you get notified when they finish:
+
+```bash
+# Watch CI, then check merge state
+gh pr checks <number> --repo <owner>/<repo> --watch && gh pr view <number> --repo <owner>/<repo> --json state --jq '.state'
+```
+
+For multiple PRs, launch one background command per PR in parallel. When each completes,
+you'll be notified automatically via a task-notification. Do NOT use sleep-based polling
+loops — `--watch` is event-driven and exits as soon as checks finish.
+
+Note: `gh pr checks --watch` exits as soon as ALL checks complete (pass or fail). If some checks
+fail while others are still running, `--watch` will continue until everything settles, then exit
+with a non-zero code. So a background `--watch` finishing = all checks done; check which failed.
+
+## Error Handling
+
+**CRITICAL**: If something goes wrong or a command fails:
+- **DO NOT** try to manually reproduce the failing steps yourself
+- **DO NOT** try to fix things by running git commands or other manual operations
+- Both scripts are idempotent and designed to handle partial completion gracefully
+- If a script continues to fail after retrying, report the error to the user and wait for instructions

+
+- The pipeline is interactive (serves to browser at the end). When running non-interactively, run the steps manually instead of using the wrapper script.
+- The three steps are: `samply record --save-only`, `symbolicate_profile.py`, then `serve_profile.py`.
+- `lean_demangle.py` works standalone as a stdin filter (like `c++filt`) for quick name lookups.
+- The `--raw` flag on `lean_demangle.py` gives exact demangled names without postprocessing (keeps `._redArg`, `._lam_0` suffixes as-is).
+- Use `PROFILE_KEEP=1` to keep the temp directory for later inspection.
+- The demangled profile is a standard Firefox Profiler JSON. Function names live in `threads[i].stringArray`, indexed by `threads[i].funcTable.name`.

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+NOTE: A full rebuild of stage 1 will only be triggered when the *committed* contents of `stage0/` are changed.
+Thus if you change files in it manually instead of through `update-stage0-commit` (see below) or fetching updates from git, you either need to commit those changes first or run `make -C build/release clean-stdlib`.

+Thus when debugging e.g. stage 2 failures, you can resume the build from these failures on but you may want to explicitly call `clean-stdlib` to either observe changes from `.olean` files of modules that built successfully or to check that you did not break modules that built successfully at some prior point.

 trigger that process, for example to be able to use new features in the compiler itself.

-* `@[export sym] def leanSym : ...` exports `leanSym` under the unmangled symbol name `sym`.
-
-For simple examples of how to call foreign code from Lean and vice versa, see <https://github.com/leanprover/lean4/blob/master/src/lake/examples/ffi> and <https://github.com/leanprover/lean4/blob/master/src/lake/examples/reverse-ffi>, respectively.
-
-## The Lean ABI
-
-The Lean Application Binary Interface (ABI) describes how the signature of a Lean declaration is encoded as a native calling convention.
-It is based on the standard C ABI and calling convention of the target platform.
-For a Lean declaration marked with either `@[extern "sym"]` or `@[export sym]` for some symbol name `sym`, let `α₁ → ... → αₙ → β` be the normalized declaration's type.
-If `n` is 0, the corresponding C declaration is
-```c
-extern s sym;
-```
-where `s` is the C translation of `β` as specified in the next section.
-In the case of an `@[extern]` definition, the symbol's value is guaranteed to be initialized only after calling the Lean module's initializer or that of an importing module; see [Initialization](#initialization).
-
-If `n` is greater than 0, the corresponding C declaration is
-```c
-s sym(t₁, ..., tₘ);
-```
-where the parameter types `tᵢ` are the C translation of the `αᵢ` as in the next section.
-In the case of `@[extern]` all *irrelevant* types are removed first; see next section.
-
-### Translating Types from Lean to C
-
-* The integer types `UInt8`, ..., `UInt64`, `USize` are represented by the C types `uint8_t`, ..., `uint64_t`, `size_t`, respectively
-* `Char` is represented by `uint32_t`
-* `Float` is represented by `double`
-* An *enum* inductive type of at least 2 and at most 2^32 constructors, each of which with no parameters, is represented by the first type of `uint8_t`, `uint16_t`, `uint32_t` that is sufficient to represent all constructor indices.
-
-  For example, the type `Bool` is represented as `uint8_t` with values `0` for `false` and `1` for `true`.
-* `Decidable α` is represented the same way as `Bool`
-* An inductive type with a *trivial structure*, that is,
-  * it is none of the types described above
-  * it is not marked `unsafe`
-  * it has a single constructor with a single parameter of *relevant* type
-
-  is represented by the representation of that parameter's type.
-
-  For example, `{ x : α // p }`, the `Subtype` structure of a value of type `α` and an irrelevant proof, is represented by the representation of `α`.
-  Similarly, the signed integer types `Int8`, ..., `Int64`, `ISize` are also represented by the unsigned C types `uint8_t`, ..., `uint64_t`, `size_t`, respectively, because they have a trivial structure.
-* `Nat` and `Int` are represented by `lean_object *`.
-  Their runtime values is either a pointer to an opaque bignum object or, if the lowest bit of the "pointer" is 1 (`lean_is_scalar`), an encoded unboxed natural number or integer (`lean_box`/`lean_unbox`).
-* A universe `Sort u`, type constructor `... → Sort u`, or proposition `p : Prop` is *irrelevant* and is either statically erased (see above) or represented as a `lean_object *` with the runtime value `lean_box(0)`
-* Any other type is represented by `lean_object *`.
-  Its runtime value is a pointer to an object of a subtype of `lean_object` (see the "Inductive types" section below) or the unboxed value `lean_box(cidx)` for the `cidx`th constructor of an inductive type if this constructor does not have any relevant parameters.
-
-  Example: the runtime value of `u : Unit` is always `lean_box(0)`.
-
-#### Inductive types
-
-For inductive types which are in the fallback `lean_object *` case above and not trivial constructors, the type is stored as a `lean_ctor_object`, and `lean_is_ctor` will return true. A `lean_ctor_object` stores the constructor index in the header, and the fields are stored in the `m_objs` portion of the object.
-
-The memory order of the fields is derived from the types and order of the fields in the declaration. They are ordered as follows:
-
-* Non-scalar fields stored as `lean_object *`
-* Fields of type `USize`
-* Other scalar fields, in decreasing order by size
-
-Within each group the fields are ordered in declaration order. **Warning**: Trivial wrapper types still count toward a field being treated as non-scalar for this purpose.
-
-* To access fields of the first kind, use `lean_ctor_get(val, i)` to get the `i`th non-scalar field.
-* To access `USize` fields, use `lean_ctor_get_usize(val, n+i)` to get the `i`th usize field and `n` is the total number of fields of the first kind.
-* To access other scalar fields, use `lean_ctor_get_uintN(val, off)` or `lean_ctor_get_usize(val, off)` as appropriate. Here `off` is the byte offset of the field in the structure, starting at `n*sizeof(void*)` where `n` is the number of fields of the first two kinds.
-
-For example, a structure such as
-```lean
-structure S where
-  ptr_1 : Array Nat
-  usize_1 : USize
-  sc64_1 : UInt64
-  ptr_2 : { x : UInt64 // x > 0 } -- wrappers don't count as scalars
-  sc64_2 : Float -- `Float` is 64 bit
-  sc8_1 : Bool
-  sc16_1 : UInt16
-  sc8_2 : UInt8
-  sc64_3 : UInt64
-  usize_2 : USize
-  ptr_3 : Char -- trivial wrapper around `UInt32`
-  sc32_1 : UInt32
-  sc16_2 : UInt16
-```
-would get re-sorted into the following memory order:
-
-* `S.ptr_1` - `lean_ctor_get(val, 0)`
-* `S.ptr_2` - `lean_ctor_get(val, 1)`
-* `S.ptr_3` - `lean_ctor_get(val, 2)`
-* `S.usize_1` - `lean_ctor_get_usize(val, 3)`
-* `S.usize_2` - `lean_ctor_get_usize(val, 4)`
-* `S.sc64_1` - `lean_ctor_get_uint64(val, sizeof(void*)*5)`
-* `S.sc64_2` - `lean_ctor_get_float(val, sizeof(void*)*5 + 8)`
-* `S.sc64_3` - `lean_ctor_get_uint64(val, sizeof(void*)*5 + 16)`
-* `S.sc32_1` - `lean_ctor_get_uint32(val, sizeof(void*)*5 + 24)`
-* `S.sc16_1` - `lean_ctor_get_uint16(val, sizeof(void*)*5 + 28)`
-* `S.sc16_2` - `lean_ctor_get_uint16(val, sizeof(void*)*5 + 30)`
-* `S.sc8_1` - `lean_ctor_get_uint8(val, sizeof(void*)*5 + 32)`
-* `S.sc8_2` - `lean_ctor_get_uint8(val, sizeof(void*)*5 + 33)`
-
-### Borrowing
-
-By default, all `lean_object *` parameters of an `@[extern]` function are considered *owned*, i.e. the external code is passed a "virtual RC token" and is responsible for passing this token along to another consuming function (exactly once) or freeing it via `lean_dec`.
-To reduce reference counting overhead, parameters can be marked as *borrowed* by prefixing their type with `@&`.
-Borrowed objects must only be passed to other non-consuming functions (arbitrarily often) or converted to owned values using `lean_inc`.
-In `lean.h`, the `lean_object *` aliases `lean_obj_arg` and `b_lean_obj_arg` are used to mark this difference on the C side.
-
-Return values and `@[export]` parameters are always owned at the moment.
-
-## Initialization
-
-When including Lean code as part of a larger program, modules must be *initialized* before accessing any of their declarations.
-Module initialization entails
-* initialization of all "constants" (nullary functions), including closed terms lifted out of other functions
-* execution of all `[init]` functions
-* execution of all `[builtin_init]` functions, if the `builtin` parameter of the module initializer has been set
-
-The module initializer is automatically run with the `builtin` flag for executables compiled from Lean code and for "plugins" loaded with `lean --plugin`.
-For all other modules imported by `lean`, the initializer is run without `builtin`.
-Thus `[init]` functions are run iff their module is imported, regardless of whether they have native code available or not, while `[builtin_init]` functions are only run for native executable or plugins, regardless of whether their module is imported or not.
-`lean` uses built-in initializers for e.g. registering basic parsers that should be available even without importing their module (which is necessary for bootstrapping).
-
-The initializer for module `A.B` is called `initialize_A_B` and will automatically initialize any imported modules.
-Module initializers are idempotent (when run with the same `builtin` flag), but not thread-safe.
-Together with initialization of the Lean runtime, you should execute code like the following exactly once before accessing any Lean declarations:
-```c
-void lean_initialize_runtime_module();
-void lean_initialize();
-lean_object * initialize_A_B(uint8_t builtin, lean_object *);
-lean_object * initialize_C(uint8_t builtin, lean_object *);
-...
-
-lean_initialize_runtime_module();
-//lean_initialize();  // necessary (and replaces `lean_initialize_runtime_module`) if you (indirectly) access the `Lean` package
-
-lean_object * res;
-// use same default as for Lean executables
-uint8_t builtin = 1;
-res = initialize_A_B(builtin, lean_io_mk_world());
-if (lean_io_result_is_ok(res)) {
-    lean_dec_ref(res);
-} else {
-    lean_io_result_show_error(res);
-    lean_dec(res);
-    return ...;  // do not access Lean declarations if initialization failed
-}
-res = initialize_C(builtin, lean_io_mk_world());
-if (lean_io_result_is_ok(res)) {
-...
-
-//lean_init_task_manager();  // necessary if you (indirectly) use `Task`
-lean_io_mark_end_initialization();
-```
-
-In addition, any other thread not spawned by the Lean runtime itself must be initialized for Lean use by calling
-```c
-void lean_initialize_thread();
-```
-and should be finalized in order to free all thread-local resources by calling
-```c
-void lean_finalize_thread();
-```
-
-## `@[extern]` in the Interpreter
-
-The interpreter can run Lean declarations for which symbols are available in loaded shared libraries, which includes `@[extern]` declarations.
-Thus to e.g. run `#eval` on such a declaration, you need to
-1. compile (at least) the module containing the declaration and its dependencies into a shared library, and then
-1. pass this library to `lean --load-dynlib=` to run code `import`ing this module.
-
-Note that it is not sufficient to load the foreign library containing the external symbol because the interpreter depends on code that is emitted for each `@[extern]` declaration.
-Thus it is not possible to interpret an `@[extern]` declaration in the same file.
-
-See [`tests/compiler/foreign`](https://github.com/leanprover/lean4/tree/master/tests/compiler/foreign/) for an example.

+just update the title in the existing release notes file (see "Release notes title format" below).
+
+## Release notes title format
+
+The title in the `#doc (Manual)` line must follow these formats:
+
+- **For -rc1**: `"Lean 4.7.0-rc1 (2024-03-15)"` — Include the RC suffix and the release date

+
+The date should be the actual date when the tag was pushed (or when CI completed and created the release page).
+
+## Generating the release notes
+
 Release notes are automatically generated from the commit history, using `script/release_notes.py`.
 
 Run this as `script/release_notes.py --since v4.6.0`, where `v4.6.0` is the *previous* release version.

+
+## Reviewing and fixing the generated markdown
+
+Before adding the release notes to the reference manual, carefully review the generated markdown for these common issues:
+
+1. **Unterminated code blocks**: PR descriptions sometimes have unclosed code fences. Look for code blocks
+   that don't have a closing ` ``` `. If found, fetch the original PR description with `gh pr view <number>`
+   and repair the code block with the complete content.
+
+2. **Truncated descriptions**: Some PR descriptions may end abruptly mid-sentence. Review these and complete
+   the descriptions based on the original PR.
+
+3. **Markdown syntax issues**: Check for other markdown problems that could cause parsing errors.
+
+## Creating the release notes file
+
+The release notes go in `Manual/Releases/v4_7_0.lean` in the reference-manual repository.
+
+The file structure must follow the Verso format:

+
+**Important formatting rules for Verso:**
+- Use `#` for section headers inside the document, not `##` (Verso uses header level 1 for subsections)
+- Use plain ` ``` ` for code blocks, not ` ```lean ` (the latter will cause Lean to execute the code)
+- Identifiers with underscores like `bv_decide` should be wrapped in backticks: `` `bv_decide` ``
+  (otherwise the underscore may be interpreted as markdown emphasis)
+
+## Updating Manual/Releases.lean
+
+After creating the release notes file, update `Manual/Releases.lean` to include it:
+
+1. Add the import near the top with other version imports:

+
+2. Add the include statement after the other includes:

+- "'_'" errors: Underscore in identifier being parsed as emphasis; wrap in backticks
+
+## Creating the PR
+
+**Important: Timing with the reference-manual tag**
+
+The reference-manual repository deploys documentation when a version tag is pushed. If you merge
+release notes AFTER the tag is created, the deployed documentation won't include them.
+
+You have two options:
+
+1. **Preferred**: Include the release notes in the same PR as the toolchain bump (or merge the

-# Test Suite
-
-After [building Lean](../make/index.md) you can run all the tests using
-```
-cd build/release
-make test ARGS=-j4
-```
-Change the 4 to the maximum number of parallel tests you want to
-allow. The best choice is the number of CPU cores on your machine as
-the tests are mostly CPU bound.  You can find the number of processors
-on linux using `nproc` and on Windows it is the `NUMBER_OF_PROCESSORS`
-environment variable.
-
-You can run tests after [building a specific stage](bootstrap.md) by
-adding the `-C stageN` argument. The default when run as above is stage 1.  The
-Lean tests will automatically use that stage's corresponding Lean
-executables
-
-Running `make test` will not pick up new test files; run
-```bash
-cmake build/release/stage1
-```
-to update the list of tests.
-
-You can also use `ctest` directly if you are in the right folder.  So
-to run stage1 tests with a 300 second timeout run this:
-
-```bash
-cd build/release/stage1
-ctest -j 4 --output-on-failure --timeout 300
-```
-Useful `ctest` flags are `-R <name of test>` to run a single test, and
-`--rerun-failed` to run all tests that failed during the last run.
-You can also pass `ctest` flags via `make test ARGS="--rerun-failed"`.
-
-To get verbose output from ctest pass the `--verbose` command line
-option. Test output is normally suppressed and only summary
-information is displayed. This option will show all test output.
-
-## Test Suite Organization
-
-All these tests are included by [src/shell/CMakeLists.txt](https://github.com/leanprover/lean4/blob/master/src/shell/CMakeLists.txt):
-
-- [`tests/lean`](https://github.com/leanprover/lean4/tree/master/tests/lean/): contains tests that come equipped with a
-  .lean.expected.out file. The driver script [`test_single.sh`](https://github.com/leanprover/lean4/tree/master/tests/lean/test_single.sh) runs
-  each test and checks the actual output (*.produced.out) with the
-  checked in expected output.
-
-- [`tests/lean/run`](https://github.com/leanprover/lean4/tree/master/tests/lean/run/): contains tests that are run through the lean
-  command line one file at a time. These tests only look for error
-  codes and do not check the expected output even though output is
-  produced, it is ignored.
-
-- [`tests/lean/interactive`](https://github.com/leanprover/lean4/tree/master/tests/lean/interactive/): are designed to test server requests at a
-  given position in the input file. Each .lean file contains comments
-  that indicate how to simulate a client request at that position.
-  using a `--^` point to the line position. Example:
-    ```lean,ignore
-    open Foo in
-    theorem tst2 (h : a ≤ b) : a + 2 ≤ b + 2 :=
-    Bla.
-      --^ textDocument/completion
-    ```
-    In this example, the test driver [`test_single.sh`](https://github.com/leanprover/lean4/tree/master/tests/lean/interactive/test_single.sh) will simulate an
-    auto-completion request at `Bla.`. The expected output is stored in
-    a .lean.expected.out in the json format that is part of the
-    [Language Server
-    Protocol](https://microsoft.github.io/language-server-protocol/).
-
-    This can also be used to test the following additional requests:
-    ```
-    --^ textDocument/hover
-    --^ textDocument/typeDefinition
-    --^ textDocument/definition
-    --^ $/lean/plainGoal
-    --^ $/lean/plainTermGoal
-    --^ insert: ...
-    --^ collectDiagnostics
-    ```
-
-- [`tests/lean/server`](https://github.com/leanprover/lean4/tree/master/tests/lean/server/): Tests more of the Lean `--server` protocol.
-  There are just a few of them, and it uses .log files containing
-  JSON.
-
-- [`tests/compiler`](https://github.com/leanprover/lean4/tree/master/tests/compiler/): contains tests that will run the Lean compiler and
-  build an executable that is executed and the output is compared to
-  the .lean.expected.out file. This test also contains a subfolder
-  [`foreign`](https://github.com/leanprover/lean4/tree/master/tests/compiler/foreign/) which shows how to extend Lean using C++.
-
-- [`tests/lean/trust0`](https://github.com/leanprover/lean4/tree/master/tests/lean/trust0): tests that run Lean in a mode that Lean doesn't
-  even trust the .olean files (i.e., trust 0).
-
-- [`tests/bench`](https://github.com/leanprover/lean4/tree/master/tests/bench/): contains performance tests.
-
-- [`tests/plugin`](https://github.com/leanprover/lean4/tree/master/tests/plugin/): tests that compiled Lean code can be loaded into
-  `lean` via the `--plugin` command line option.
-
-## Writing Good Tests
-
-Every test file should contain:
-* an initial `/-! -/` module docstring summarizing the test's purpose
-* a module docstring for each test section that describes what is tested
-  and, if not 100% clear, why that is the desirable behavior
-
-At the time of writing, most tests do not follow these new guidelines yet.
-For an example of a conforming test, see [`tests/lean/1971.lean`](https://github.com/leanprover/lean4/tree/master/tests/lean/1971.lean).
-
-## Fixing Tests
-
-When the Lean source code or the standard library are modified, some of the
-tests break because the produced output is slightly different, and we have
-to reflect the changes in the `.lean.expected.out` files.
-We should not blindly copy the new produced output since we may accidentally
-miss a bug introduced by recent changes.
-The test suite contains commands that allow us to see what changed in a convenient way.
-First, we must install [meld](http://meldmerge.org/). On Ubuntu, we can do it by simply executing
-
-```
-sudo apt-get install meld
-```
-
-Now, suppose `bad_class.lean` test is broken. We can see the problem by going to [`tests/lean`](https://github.com/leanprover/lean4/tree/master/tests/lean) directory and
-executing
-
-```
-./test_single.sh -i bad_class.lean
-```
-
-When the `-i` option is provided, `meld` is automatically invoked
-whenever there is discrepancy between the produced and expected
-outputs. `meld` can also be used to repair the problems.
-
-In Emacs, we can also execute `M-x lean4-diff-test-file` to check/diff the file of the current buffer.
-To mass-copy all `.produced.out` files to the respective `.expected.out` file, use `tests/lean/copy-produced`.

+    .text "Usually, for every operation `f`, there will be functions `String.f` and `String.Slice.f`, where `String.f s` is defined as `String.Slice.f s.toSlice`.",
+    .text "In particular, functions that transform strings and slices should live in the `String` and `String.Slice` namespaces even if they involve a `String.Pos`/`String.Slice.Pos` (like `String.sliceTo`), for reasons that will become clear shortly.",

+    .text "For example, given a string `s` and a position `p` on `s`, we have the slice `s.sliceFrom p`, which is the slice from `p` to the end of `s`. A position on `s.sliceFrom p` can always be interpreted as a position on `s`. This is the \"backwards\" transformation. Conversely, a position `q` on `s` can be interpreted as a position on `s.sliceFrom p` as long as `p ≤ q`. This is the conditional forwards direction.",
+    .text "The convention for naming these transformations is that the forwards transformation should have the same name as the transformation on strings/slices, but it should be located in the `String.Pos` or `String.Slice.Pos` namespace, depending on the type of the starting position (so that dot notation is possible for the forward direction). The backwards transformation should have the same name as the operation on strings/slices, but with an `of` prefix, and live in the same namespace as the forwards transformation (so in general dot notation will not be available).",

+    .text "Sometimes there is a name clash for the panicking operations if the operation on strings is already panicking. For example, there are both `String.slice` and `String.slice!`. If the original operation is already panicking, we only provide panicking transformation operations. But now `String.Pos.slice!` could refer both to the panicking forwards transformation associated with `String.slice`, and also to the (only) forwards transformation associated with `String.slice!`. In this situation, we use an `orPanic` suffix to disambiguate. So the panicking forwards operation associated with `String.slice` is called `String.Pos.sliceOrPanic`, and the forwards operation associated with `String.slice!` is called `String.Pos.slice!`."

+#### Tactics
+
+Docstrings for tactics should have the following structure:
+
+* Short summary
+* Details
+* Variants
+* Examples
+
+Sometimes more than one declaration is needed to implement what the user
+sees as a single tactic. In that case, only one declaration should have
+the associated docstring, and the others should have the `tactic_alt`
+attribute to mark them as an implementation detail.
+
+The **short summary** should be 1–3 sentences (ideally 1) and provide
+enough information for most readers to quickly decide whether the
+tactic is relevant to their task. The first (or only) sentence of
+the short summary should be a full sentence in which the subject
+is an example invocation of the tactic, written in present tense
+indicative. If the example tactic invocation names parameters, then the
+short summary may refer to them. For the example invocation, prefer the
+simplest or most typical example. Explain more complicated forms in the
+variants section. If needed, abbreviate the invocation by naming part of
+the syntax and expanding it in the next sentence. The summary should be
+written as a single paragraph.
+
+**Details**, if needed, may be 1-3 paragraphs that describe further
+relevant information. They may insert links as needed. This section
+should fully explain the scope of the tactic: its syntax format,
+on which goals it works and what the resulting goal(s) look like. It
+should be clear whether the tactic fails if it does not close the main
+goal and whether it creates any side goals. The details may include
+explanatory examples that can’t necessarily be machine checked and
+don’t fit the format.
+
+If the tactic is extensible using `macro_rules`, mention this in the
+details, with a link to `lean-manual://section/tactic-macro-extension`
+and give a one-line example. If the tactic provides an attribute or a
+command that allows the user to extend its behavior, the documentation
+on how to extend the tactic belongs to that attribute or command. In the
+tactic docstring, use a single sentence to refer the reader to this
+further documentation.
+
+**Variants**, if needed, should be a bulleted list describing different
+options and forms of the same tactic. The reader should be able to parse
+and understand the parts of a tactic invocation they are hovering over,
+using this list. Each list item should describe an individual variant
+and take one of two formats: the **short summary** as above, or a
+**named list item**. A named list item consists of a title in bold
+followed by an indented short paragraph.
+
+Variants should be explained from the perspective of the tactic's users, not
+their implementers. A tactic that is implemented as a single Lean parser may
+have multiple variants from the perspective of users, while a tactic that is
+implemented as multiple parsers may have no variants, but merely an optional
+part of the syntax.
+
+**Examples** should start with the line `Examples:` (or `Example:` if
+there’s exactly one). The section should consist of a sequence of code
+blocks, each showing a Lean declaration (usually with the `example`
+keyword) that invokes the tactic. When the effect of the tactic is not
+clear from the code, you can use code comments to describe this. Do
+not include text between examples, because it can be unclear whether
+the text refers to the code before or after the example.
+
+##### Example
+
+````
+`rw [e]` uses the expression `e` as a rewrite rule on the main goal,
+then tries to close the goal by "cheap" (reducible) `rfl`.
+
+If `e` is a defined constant, then the equational theorems associated with `e`
+are used. This provides a convenient way to unfold `e`. If `e` has parameters,
+the tactic will try to fill these in by unification with the matching part of
+the target. Parameters are only filled in once per rule, restricting which
+later rewrites can be found. Parameters that are not filled in after
+unification will create side goals. If the `rfl` fails to close the main goal,
+no error is raised.
+
+`rw` may fail to rewrite terms "under binders", such as `∀ x, ...` or `∃ x,
+...`. `rw` can also fail with a "motive is type incorrect" error in the context
+of dependent types. In these cases, consider using `simp only`.
+
+* `rw [e₁, ... eₙ]` applies the given rules sequentially.
+* `rw [← e]` or `rw [<- e]` applies the rewrite in the reverse direction.
+* `rw [e] at l` rewrites with `e` at location(s) `l`.
+* `rw (occs := .pos L) [e]`, where `L` is a literal list of natural numbers,
+  only rewrites the given occurrences in the target. Occurrences count from 1.
+* `rw (occs := .neg L) [e]`, where `L` is a literal list of natural numbers,
+  skips rewriting the given occurrences in the target. Occurrences count from 1.
+
+Examples:
+
+```lean
+example {a b : Nat} (h : a + a = b) : (a + a) + (a + a) = b + b := by rw [h]
+```
+
+```lean
+example {f : Nat -> Nat} (h : ∀ x, f x = 1) (a b : Nat) : f a = f b := by
+  rw [h] -- `rw` instantiates `h` only once, so this is equivalent to: `rw [h a]`
+  -- goal: ⊢ 1 = f b
+  rw [h] -- equivalent to: `rw [h b]`
+```
+````
