Subject: [PATCH 01/43] fix: RS03 recognize tries all known medium sizes as
 candidates

Replace single-guess layer size selection with multi-candidate search.
Both DM and NODM BD sizes are always tried, removing the need for
--no-bdr-defect-management at recognition time. Fixes recognition
of RS03 ECC data when image sector count doesn't match expected
medium size (BD-RE read-back, DM/NODM mismatch).

Addresses upstream issues speed47/dvdisaster#69, #97, #135.

Subject: [PATCH 02/43] fix: suppress verbose noise from RS03 candidate loop,
 fix deb build

RS03 multi-candidate search was producing verbose output for every
candidate tried, breaking bash regtest golden-file comparisons. Now
only the first candidate (matching old single-guess behavior) emits
verbose output; subsequent candidates run quietly. Also reorder
exhaustive candidates to try heuristic_layer_size() first.

Fix deb build: dpkg-buildpackage calls make distclean before configure,
hitting the stub Makefile. Override dh_auto_clean to skip when
GNUmakefile.config doesn't exist.

Subject: [PATCH 03/43] fix: update regtest golden files for multi-candidate
 RS03 recognize
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the "trying image-derived layer sizes" verbose output blocks
from 32 golden database files. The RS03 multi-candidate search
(commit f8d747f) replaced the old two-phase recognize flow with a
single candidate loop where only the first candidate is verbose.
The removed blocks contained image-derived size attempts that all
failed—the new code still tries these sizes but quietly.

Subject: [PATCH 04/43] test: add pytest framework and RS03 recognition
 robustness tests

Seed a new Python/pytest test framework alongside the existing bash
regtests. New tests are integration tests that invoke the dvdisaster
binary and check output, same approach as the bash tests but with
structured assertions instead of golden-file comparison.

New tests:
- test_padded_image_recognized: RS03 found in image padded with
  extra sectors (BD-RE read-back scenario, upstream #97)
- test_heavily_padded_image: RS03 found even with 2x padding
- test_nodm_image_without_flag: RS03 NODM image recognized
  without --no-bdr-defect-management flag (upstream #69)
- test_nodm_image_with_flag_still_works: sanity check

CI runs pytest on Linux after the existing regression tests.

Subject: [PATCH 05/43] enh: add golden-test framework for declarative
 regression tests

Implements a Python/pytest framework (tests/framework.py) that provides:
- Damage operation dataclasses (Erase, Byteset, Truncate, PadBytes, PadSectors)
- Golden file parser matching regtest/database/ format
- Output cleaning that mirrors bash run_regtest filtering
- GoldenTestSuite base class with automatic parametrization
- 28 unit tests and 3 smoke tests using real RS01 golden files

Subject: [PATCH 06/43] enh: migrate all 28 RS01 verify tests from bash to
 Python

Replace the 3-test smoke file with complete coverage of all RS01 verify
tests from regtest/rs01.bash. Fix framework ecc_damage copy naming to
match bash convention (master -> tmp) for golden file comparison.

Subject: [PATCH 07/43] enh: migrate all 144 RS01 tests from bash to Python,
 disable bash tests

Migrate creation, repair, scanning, linear reading, and adaptive reading
tests to the declarative GoldenTestSuite framework. Fix subprocess stdin
(DEVNULL), add missing ECC MD5 check, remove unused _master_cache.
All 145 Python tests pass (143 pass, 2 skip for missing golden files).

Subject: [PATCH 08/43] enh: migrate all 148 RS02 tests from bash to Python,
 disable bash tests

RS02 (augmented image codec) test migration:
- 149 pytest tests (147 pass, 2 skip placeholder), covering all 148 bash tests
- 7 test classes: Strip, Verify, Create, Repair, Scan, ReadLinear, ReadAdaptive
- read_multipass_ecc_partial_success covered by existing test_multipass_read.py

Framework enhancements:
- Add AppendFile damage op for appending file contents to images
- Add ignore_lines param to clean_output() (mirrors bash IGNORE_LOG_LINE)
- Add --debug to sim_cd handling (required by --fixed-speed-values)

Subject: [PATCH 09/43] fix: wire CreateECC output/ecc_size fields, fix path
 stripping fidelity

- CreateECC.output and ecc_size now generate -o and -n CLI args
- ISODIR/TMPDIR path removal now matches without trailing slash
  (matching bash sed "s=$TMPDIR/*==g" semantics)

Subject: [PATCH 10/43] enh: migrate RS03f verify tests (34 tests) from bash to
 Python

Port all 34 verify test cases from regtest/rs03f.bash lines 48-517 to
tests/test_rs03f.py using the GoldenTestSuite framework. Includes 14
declarative GoldenTest entries and 20 manual test methods for complex
setup scenarios (plus56, special padding, ecc file manipulation, DSM).

 RS03f is the file-based ECC mode: ECC data is stored in a separate .ecc file
 (like RS01), but uses the RS03 codec with configurable redundancy roots.
 
 Tests are grouped into:
   - TestRS03fVerify: 39 verify tests
+  - TestRS03fCreate: 14 creation tests
+  - TestRS03fRepair: 25 repair/fix tests

Subject: [PATCH 14/43] enh: migrate RS03f reading tests (18) from bash to
 Python

Adds TestRS03fReadLinear (17 tests) and TestRS03fReadAdaptive (1 test).
read_multipass_ecc_partial_success is already in test_multipass_read.py.

Subject: [PATCH 15/43] fix: address code quality review for RS03f reading
 tests

- Add ecc_path=master_ecc to read_good and adaptive_good for ECC MD5 verification
- Use positional args for _append_fixed_random_sequence (consistent with scan tests)
- Use single quotes for ignore_line_re (consistent with scan tests)

Subject: [PATCH 16/43] enh: migrate RS03i strip + verify tests (50) from bash
 to Python

Creates test_rs03i.py with TestRS03iStrip (2 tests) and TestRS03iVerify
(48 tests). Includes helpers for raw, master, large master, custom master,
and LMI variant images. Fixes none.file ecc path for tests where dvdisaster
reports a missing ecc file in its output.

+# dvdisaster Test Suite
+
+This directory contains the Python/pytest integration test suite for dvdisaster. It is replacing the legacy bash-based regression tests in `regtest/` with a declarative, maintainable framework.
+
+## Quick Start
+
+```bash
+# Build dvdisaster first
+./configure --with-gui=no && make -j$(nproc)
+
+# Run all tests
+pip install pytest
+python3 -m pytest tests/ -v
+
+# Run a single codec
+python3 -m pytest tests/test_rs01.py -v
+
+# Run a specific test class
+python3 -m pytest tests/test_rs02.py::TestRS02Verify -v
+
+# Run a specific test
+python3 -m pytest "tests/test_rs01.py::TestRS01Verify::test_golden[good]" -v
+```
+
+Master images are cached in `/var/tmp/regtest/` (created on first run, reused thereafter). The first run is slower because it creates these images.
+
+## Test Count
+
+| File | Tests | Status |
+|------|------:|--------|
+| `test_rs01.py` | 145 | Migrated from bash (143 pass, 2 skip) |
+| `test_rs02.py` | 149 | Migrated from bash (147 pass, 2 skip) |
+| `test_multipass_read.py` | 4 | Semantic tests (all codecs) |
+| `test_rs03_recognize.py` | 4 | Semantic tests (RS03 recognition) |
+| `test_framework.py` | 28 | Unit tests for the framework itself |
+| **Total** | **330** | |
+
+Skipped tests are placeholder entries (`golden_test0`) in classes that define no declarative golden tests -- they have no effect and will be removed when the framework drops the placeholder requirement.
+
+## Architecture
+
+### Framework (`framework.py`)
+
+The framework provides a declarative DSL for defining regression tests. Instead of writing imperative bash scripts, tests are declared as data:
+
+```python
+class TestRS01Verify(GoldenTestSuite):
+    codec = "RS01"
+    codec_prefix = "RS01"
+    master = "rs01-master.iso"
+    master_ecc = "rs01-master.ecc"
+
+    tests = [
+        GoldenTest("good", action="-t", use_master=True, ecc="master_ecc"),
+        GoldenTest("missing_sectors", action="-t",
+                   damage=[Erase("1500-1673"), Erase("13420-14109")],
+                   ecc="master_ecc"),
+    ]
+```
+
+The `GoldenTestSuite` base class converts each `GoldenTest` entry into a parametrized pytest test case at collection time. The execution flow for each test:
+
+1. Create temp work directory (pytest `tmp_path`)
+2. Resolve image path (master, custom, or new empty path)
+3. Apply damage operations (erase sectors, set bytes, truncate, pad, append files)
+4. Handle simulated CD reading (`sim_cd`) if specified
+5. Run: `dvdisaster --regtest --no-progress -i<image> [-e<ecc>] <action> [extra_args]`
+6. Clean output (strip headers, paths, memory-leak lines, `ignore_lines` patterns)
+7. Compare cleaned output against golden reference file
+8. Verify MD5 checksums if specified in the golden file
+
+### Damage Operations
+
+Atomic operations applied to images before running dvdisaster:
+
+| Operation | Description | Implementation |
+|-----------|-------------|----------------|
+| `Erase("15800-16199")` | Zero out sector range | CLI: `--erase` |
+| `Erase("100:hardware failure")` | Erase with sim label | CLI: `--erase` |
+| `Erase("500", fill_unreadable=0)` | Erase + fill pattern | CLI: `--erase --fill-unreadable` |
+| `Byteset(4096, 100, 17)` | Set byte at sector/offset | CLI: `--byteset` |
+| `Truncate(20500)` | Truncate image to N sectors | CLI: `--truncate` |
+| `PadBytes(55)` | Append N zero bytes | Python-level |
+| `PadSectors(17)` | Append N×2048 zero bytes | Python-level |
+| `AppendFile(path)` | Append file contents | Python-level |
+
+CLI operations invoke `dvdisaster --debug` to modify the image. Python-level operations modify the file directly with `open()`.
+
+### SimCD (Simulated CD Reading)
+
+For scan and read tests, `SimCD` simulates reading from a damaged disc:
+
+```python
+GoldenTest("scan_missing_sectors", action="-s",
+           sim_cd=SimCD(source="master",
+                        damage=[Erase("1000-1049"), Erase("21230")]))
+```
+
+When `sim_cd` is present, the framework:
+1. Copies the source image to `sim.iso` in the work directory
+2. Applies sim-cd damage operations
+3. Adds `--debug --sim-cd=<path> --fixed-speed-values --spinup-delay=0` to the command
+
+### Golden Files
+
+Golden reference files live in `regtest/database/` and have this format:
+
+```
+<image_md5 or "ignore">
+<ecc_md5 or "ignore">
+<expected output...>
+```
+
+Platform-specific variants are supported: `RS01_good.darwin` (macOS), `RS01_good.win` (Windows), with fallback to the base file.
+
+### Output Cleaning
+
+Before comparison, output is cleaned to ensure reproducibility:
+
+- Strip version/copyright header (first 3 lines)
+- Remove `dvdisaster: No memory leaks found.` lines
+- Remove temp directory paths and Windows drive letters
+- Remove `regtest/` prefix from paths
+- Remove lines matching `ignore_lines` regex patterns (mirrors bash `IGNORE_LOG_LINE`)
+
+## Test Files
+
+### `test_rs01.py` -- RS01 (Separate ECC File)
+
+RS01 creates a separate `.ecc` file alongside the image. Tests use a 21000-sector master image and a pre-built master ECC file.
+
+| Class | Tests | What it covers |
+|-------|------:|----------------|
+| `TestRS01Verify` | 28 | Image+ECC verification: good, truncated, missing sectors, bad bytes, CRC errors, cross-codec detection |
+| `TestRS01Create` | 11 | ECC creation: normal, with existing image/ECC, missing image, permission errors, non-blocksize images |
+| `TestRS01Repair` | 18 | Image repair: truncated, missing sectors, bad bytes, permission errors, with wrong ECC fingerprint |
+| `TestRS01Scan` | 22 | Simulated CD scanning: good/defective media, range errors, skip sizes, hardware failures, DSM |
+| `TestRS01ReadLinear` | 38 | Linear reading: good/defective media, range errors, TAO tail, fingerprint mismatch, CRC errors, multipass |
+| `TestRS01ReadAdaptive` | 25 | Adaptive reading: same scenarios using divide-and-conquer algorithm, hardware failures, DSM |
+
+Notable test patterns:
+- **Cross-codec detection**: Verifying RS02/RS03 images with RS01 tool correctly identifies the codec mismatch
+- **TAO tail**: Trailing garbage bytes from Track-At-Once burning; dvdisaster should detect and handle them
+- **Hardware failure simulation**: `Erase("5000:hardware failure")` marks sectors as having drive-level read errors
+- **Multipass reading**: `--read-medium=3` tests multiple reading passes with progressively more sectors recovered
+
+### `test_rs02.py` -- RS02 (Augmented Image)
+
+RS02 embeds ECC data directly in the image (no separate `.ecc` file). Tests use a 30000-sector raw image augmented to 35000 sectors.
+
+| Class | Tests | What it covers |
+|-------|------:|----------------|
+| `TestRS02Strip` | 2 | Stripping ECC data from augmented images |
+| `TestRS02Verify` | 31 | Image verification: good, truncated, padded, bad/missing headers, modulo glitch, cross-codec |
+| `TestRS02Create` | 18 | ECC creation: normal, from other codecs, after read, partial read, non-blocksize |
+| `TestRS02Repair` | 25 | Image repair: truncated, trailing bytes/TAO/garbage, large file, permission errors, cross-codec |
+| `TestRS02Scan` | 22 | Simulated CD scanning: good/defective media, TAO tail, modulo glitch, cross-codec |
+| `TestRS02ReadLinear` | 28 | Linear reading: good/defective media, TAO tail, modulo glitch, CRC errors, cross-codec |
+| `TestRS02ReadAdaptive` | 22 | Adaptive reading: same scenarios using divide-and-conquer |
+
+Notable test patterns:
+- **Modulo glitch**: Simulates pre-0.79.5 dvdisaster headers where sector size info was missing. Uses `_apply_old_style_headers()` to patch 21 header positions with corrected checksums
+- **Header modulo glitch (HMG) image**: A 274300-sector image specifically sized to trigger the modulo-glitch code path
+- **Large file test**: Creates a 223456-sector (~450MB) image to test repair across all three RS02 sections (data, CRC, ECC)
+- **Cross-codec creation**: Tests creating RS02 ECC on images that already have RS01/RS03 ECC data
+
+### `test_multipass_read.py` -- Multipass Reading (All Codecs)
+
+Semantic tests (not golden-file) for multipass reading across RS01, RS02, RS03f (file mode), and RS03i (image mode). These replace flaky bash tests where golden-file comparison was unreliable due to timing-dependent output ordering.
+
+Each test:
+1. Creates a 21000-sector image with damaged sectors (15900-16099)
+2. Creates codec-specific ECC data
+3. Prepares a simulated CD with additional damage and "readable in pass 3" sectors
+4. Reads with `--read-medium=3` (3 passes)
+5. Asserts semantic properties: CRC errors reported, pass transitions occur, correct final sector counts
+
+### `test_rs03_recognize.py` -- RS03 Recognition Robustness
+
+Semantic tests for RS03 ECC recognition edge cases:
+- **BD-RE read-back**: Image padded with extra sectors (the drive returns full formatted capacity)
+- **Headerless recognition**: RS03 ECC data found even when the primary header is missing
+- **NODM without flag**: Images created with `--no-bdr-defect-management` recognized without the flag
+
+### `test_framework.py` -- Framework Unit Tests
+
+Unit tests for the framework itself (28 tests):
+- Damage operation CLI argument generation
+- Golden file parsing (MD5 extraction, output extraction)
+- Output cleaning (header stripping, path removal, memory-leak filtering)
+- `GoldenTest` and `SimCD` dataclass construction
+
+## Bash vs Python: Comparison
+
+### Side-by-Side Example
+
+The same test in both frameworks:
+
+**Bash** (`regtest/rs01.bash`):
+```bash
+if try "scanning defective media, no ecc" scan_defective_no_ecc; then (
+  cp $MASTERISO $SIMISO
+  $NEWVER --debug -i$SIMISO --erase 100-200 >>$LOGFILE 2>&1
+  $NEWVER --debug -i$SIMISO --erase 766 >>$LOGFILE 2>&1
+  $NEWVER --debug -i$SIMISO --erase 2410 >>$LOGFILE 2>&1
+
+  extra_args="--debug --sim-cd=$SIMISO --fixed-speed-values"
+  run_regtest scan_defective_no_ecc "--spinup-delay=0 -s" $ISODIR/no.iso $ISODIR/no.ecc
+) & limit_jobs; fi
+```
+
+**Python** (`tests/test_rs01.py`):
+```python
+GoldenTest("scan_defective_no_ecc", action="-s",
+           image="no.iso", ecc="no.ecc",
+           sim_cd=SimCD(source="master", damage=[
+               Erase("100-200"), Erase("766"), Erase("2410"),
+           ]),
+           extra_args=["--debug"]),
+```
+
+### Comparison Table
+
+| Aspect | Bash (`regtest/`) | Python (`tests/`) |
+|--------|-------------------|-------------------|
+| **Test count** | 569 (145 RS01 + 150 RS02 + 160 RS03i + 114 RS03f) | 330 (145 RS01 + 149 RS02 + 8 semantic + 28 framework) |
+| **Migration status** | RS01/RS02 disabled | RS01/RS02 migrated; RS03f/RS03i pending |
+| **Test declaration** | Imperative shell scripts (~100-300 LOC each) | Declarative DSL (data + base class) |
+| **Lines per test** | 5-15 lines of bash | 2-5 lines of Python (golden tests) |
+| **Assertion style** | Golden-file diff only | Hybrid: golden-file + semantic assertions |
+| **Timing-sensitive tests** | Flaky (exact output match) | Stable (semantic property checks) |
+| **Golden files** | Same `regtest/database/` directory | Same files, reused in place |
+| **Master image caching** | `/var/tmp/regtest/` | Same directory, compatible |
+| **Parallelism** | `MAX_JOBS` background subshells | pytest-xdist (future), sequential now |
+| **Platform variants** | Manual `.darwin`/`.win` suffix files | Same files, auto-detected |
+| **Output cleaning** | `grep -v`, `sed`, shell filters | `clean_output()` function |
+| **CI integration** | `regtest/runtests.sh` in workflow | `python3 -m pytest tests/` in workflow |
+| **Run time (RS01+RS02)** | ~45 min | ~75 min (sequential; parallelism planned) |
+| **Error messages** | Binary pass/fail | Unified diff with context |
+| **Skip mechanism** | `config.txt` toggles | `pytest.skip()` with reason |
+| **Dependencies** | bash, coreutils | Python 3.6+, pytest |
+| **Debugging** | Manual `diff` against newlog | `--tb=long`, `-s` for stdout, `--pdb` |
+
+### What Stayed the Same
+
+- Golden reference files in `regtest/database/` are reused as-is (no conversion needed)
+- Master images cached in `/var/tmp/regtest/` are shared between both frameworks
+- The `--regtest` and `--no-progress` flags are used identically
+- Output cleaning logic mirrors the bash `run_regtest` filtering exactly
+- Both frameworks run in CI via `.github/workflows/tests.yml`
+
+### What Changed
+
+- **Timing-sensitive tests** (multipass reading) use semantic assertions instead of golden-file comparison, eliminating platform-dependent flakiness
+- **Boilerplate elimination**: damage setup, sim-cd wiring, golden file lookup, and output cleaning are handled by the framework, not repeated in each test
+- **`--debug` for sim-cd** is now automatically added by the framework (required by `--fixed-speed-values`), reducing a common source of test-writing errors
+- **`ignore_lines`** parameter in `clean_output()` replaces bash `IGNORE_LOG_LINE` for filtering timing-dependent output lines
+- **`AppendFile`** damage operation replaces `cat file >> image` for TAO tail tests
+
+## Migration Status
+
+| Codec | Bash Tests | Python Tests | Status |
+|-------|-----------|-------------|--------|
+| RS01 | 145 (disabled) | 145 | Migrated |
+| RS02 | 150 (disabled) | 149 | Migrated |
+| RS03i | 160 (active) | -- | Pending |
+| RS03f | 114 (active) | -- | Pending |
+
+The 1-test difference in RS02 is because 2 bash entries (`adaptive_with_rs03_file`, `adaptive_with_wrong_rs03_file`) were discovered to be linear read tests (not adaptive) already covered by `read_with_rs03_file` and `read_with_wrong_rs03_file`, plus `read_multipass_ecc_partial_success` lives in `test_multipass_read.py`.
+
+During migration, both bash and Python tests can coexist. Migrated codecs have their bash tests disabled in `regtest/config.txt` and annotated with a comment pointing to the Python replacement.
+
+## Adding New Tests
+
+### Golden test (declarative)
+
+Add to the `tests` list in the appropriate `GoldenTestSuite` subclass:
+
+```python
+GoldenTest("my_new_test", action="-t",
+           damage=[Erase("100-200"), Byteset(300, 0, 255)],
+           ecc="master_ecc"),
+```
+
+Then run the test to generate output, and create the golden file from the actual output.
+
+### Semantic test (plain method)
+
+Add a method to the test class:
+
+```python
+def test_my_complex_scenario(self, tmp_path):
+    """Tests that can't use golden comparison."""
+    # Custom setup, assertions, etc.
+```
+
+### Framework test
+
+Add to `test_framework.py` for testing framework internals (damage ops, parsing, cleaning).

+### `test_rs03f.py` -- RS03f (File-Based ECC, RS03 Algorithm)

Subject: [PATCH 26/43] fix: resolve remaining 17 Windows pytest failures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three clusters of failures addressed:

1. plus56 family (4 tests): plus56_images fixture and _ensure_master/
   _ensure_master_ecc in test_rs01.py were racing under pytest-xdist —
   worker A started creating an ECC, worker B saw isfile=True on the
   partial file and skipped creation, then worker B's tests failed with
   "No error correction file present." Guard each path with FileLock,
   matching the pattern in framework.py's GoldenTestSuite.

2. no_device tests (3 tests): adaptive_no_device, scan_no_device,
   read_no_device used "/dev/sdz", but dvdisaster.exe echoes this path
   back verbatim. The legacy bash tests switched to "V:" on Windows
   and the existing .win golden variants expect that. Do the same here.

3. chmod-dependent tests (10 tests): POSIX chmod 0o000/0o400 is not
   honored on NTFS, so the Windows dvdisaster build cannot trigger
   "permission denied". Skip these on win32:
   - RS01 test_ecc_no_read_perm, test_ecc_no_write_perm
   - RS01 test_{scan,read,adaptive}_no_device_access
   - RS01 test_{scan,read,adaptive}_with_no_permission_for_ecc
   - RS03f test_ecc_no_read_perm, test_ecc_no_write_perm

Subject: [PATCH 27/43] fix: normalize CRLF in pytest golden comparison for
 Windows

The mingw build of dvdisaster.exe writes CRLF line endings to stdout,
while the golden reference files use LF. Every line in the Windows
pytest output therefore ended with \r, causing every golden comparison
to fail.

Normalize \r\n -> \n at the start of clean_output() and add a unit
test.

Subject: [PATCH 28/43] fix: drop empty-parametrize placeholders from
 test_golden collection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test classes that inherit test_golden for a uniform base API but have
no golden-table entries (TestRS01Create, TestRS01ReadAdaptive,
TestRS02Create, TestRS02Strip, TestRS03fCreate, TestRS03iStrip) caused
pytest to emit one skipped placeholder each — 6 fake skips per run
that corresponded to no real test body and inflated the skip count.

Filter these out in pytest_collection_modifyitems by detecting the
NotSetType sentinel pytest uses for empty parametrize lists. Match by
class name rather than importing the private symbol so we survive
pytest internal-API moves across versions.

Subject: [PATCH 29/43] enh: add pytest integration tests to macOS and Windows
 CI

Previously only Linux ran the Python test suite. macOS and Windows only
ran the bash runtests.sh which now skips everything. Added pytest step
to all three platforms and installed Python in MSYS2 for Windows.

Subject: [PATCH 30/43] fix: fix pytest install for macOS (PEP 668) and Windows
 (MSYS2 pacman)

macOS 15 runners enforce PEP 668 externally-managed-environment, so use
--break-system-packages for pip. Windows MSYS2 installs pytest via
pacman (mingw-w64-x86_64-python-pytest) instead of pip.

Bare `pip` installs to a different Python than `python3` on macOS 15
runners (pip→3.13, python3→3.14), causing "No module named pytest".

Master images (~3GB) were recreated from scratch on every CI run,
causing 3+ hour test times on macOS/Windows. Now cached via
actions/cache with keys based on OS and test file hashes.

 ### Framework test
 
 Add to `test_framework.py` for testing framework internals (damage ops, parsing, cleaning).

+## Slow Tests and CI Strategy
+
+Tests that create large master images (200+ MB) are marked with `@pytest.mark.slow` and skipped by default. Run them with:
+
+```bash
+python3 -m pytest tests/ -v --run-slow
+```
+
+### What counts as slow
+
+Tests are marked slow if they create or depend on large master images that take 2+ minutes to generate:
+- RS03i large-image tests (header recovery, root discovery): 235219-sector (~460MB) image
+- RS02 modulo-glitch tests: 274300-sector (~535MB) image
+- RS02 large-file repair test: 223456-sector (~436MB) image
+
+Currently 41 tests are marked slow (24 in RS03i, 17 in RS02).
+
+### CI strategy
+
+| Platform | Pytest runs on | Slow tests | Cache |
+|----------|---------------|------------|-------|
+| Linux | CLI build only | Yes (`--run-slow`) | `/var/tmp/regtest` |
+| macOS | CLI build only | No (skipped) | `/var/tmp/regtest` |
+| Windows | CLI build only | No (skipped) | `C:\msys64\var\tmp\regtest` |
+
+GUI and CLI builds produce identical regression test output (tests use `--regtest` mode), so we only run pytest on CLI builds to halve CI time.
+
+Slow tests run only on Linux because it's the fastest CI platform. Master images are cached via `actions/cache` to avoid recreating them on every run.

Subject: [PATCH 39/43] fix: rewrite bionic apt sources to
 old-releases.ubuntu.com in appimage build

Ubuntu 18.04 reached end-of-standard-support on 2023-04-30; the main,
updates, and backports pockets were moved off archive.ubuntu.com,
breaking the linux64-appimage job's prerequisite install with connection
timeouts and "no installation candidate" errors. Rewrite the apt
sources before update so packages resolve. The build remains pinned to
bionic to preserve the AppImage's glibc 2.27 compatibility floor.

Subject: [PATCH 40/43] docs: add CI workflow reference at
 docs/workflow_readme.md

Documents each workflow's purpose, the slow-test gating strategy, and
the AppImage / bionic-EOL apt-rewrite rationale. Establishes a new
docs/ directory in the upstream tree.

+# CI Workflow Reference
+
+This document describes the GitHub Actions workflows in `.github/workflows/`. Each workflow has a single coherent purpose; this file explains the orchestration that's not obvious from the YAML alone.
+
+## tests.yml — Regression tests
+
+Triggered on push and pull_request. Runs the pytest suite (`tests/`) on Linux, macOS (x86_64 + arm64), and Windows (MSYS2/MINGW64), for both CLI and GUI build variants. The full pytest suite is gated:
+
+- **PR / push events**: fast tests only. Runs in ~5–10 minutes per platform.
+- **Scheduled cron, release tags (`v*`), and manual `workflow_dispatch`**: full suite including slow tests (large-image RS02 / RS03i tests).
+
+Slow tests are marked with `@pytest.mark.slow` in `tests/test_rs02.py` and `tests/test_rs03i.py`. The `--run-slow` pytest option (defined in `tests/conftest.py`) opts them in; CI passes it conditionally.
+
+The first test run on any host creates ~3GB of master images in `/var/tmp/regtest/` and reuses them on subsequent runs. CI caches this directory between runs to save startup time.
+
+## release.yml — Multi-platform release builds
+
+Triggered on push to master/dev and on `v*` tags. Produces:
+
+- `linux64-cli` — static CLI binary
+- `linux64-deb` — Debian package
+- `linux64-appimage` — AppImage built inside `ubuntu:18.04` Docker container
+- `win (cli)` / `win (gui)` — Windows binaries via MSYS2/MINGW64
+- `mac (cli, x86_64 / arm64)` / `mac (gui, x86_64 / arm64)` — macOS binaries
+
+A `prepare-tag` job runs first to avoid tag race conditions between parallel platform builds.
+
+### AppImage build note
+
+The AppImage job intentionally builds inside `ubuntu:18.04` (Bionic) to keep the resulting AppImage's glibc dependency at 2.27 — the lowest common denominator across modern Linux distros, which maximizes downstream compatibility.
+
+Bionic reached end-of-standard-support on 2023-04-30. The main, updates, and backports apt pockets were moved off `archive.ubuntu.com` to `old-releases.ubuntu.com`. The "install prerequisites in docker" step rewrites `/etc/apt/sources.list` to point at `old-releases.ubuntu.com` before `apt update` so package installation succeeds. The `bionic-security` pocket on `security.ubuntu.com` is also rewritten for consistency.
+
+## codeql.yml — Static analysis
+
+Triggered on push, pull_request, and weekly cron. Runs CodeQL static analysis. No special configuration.
+
+## stale.yml — Issue housekeeping
+
+Triggered on daily cron. Auto-closes issues labeled `needs-more-info` or `answered` after a quiet period.

Subject: [PATCH 41/43] fix: switch appimage apt mirror from old-releases to
 azure.archive.ubuntu.com

The previous fix (5371514) was based on a wrong premise: bionic is NOT on
old-releases.ubuntu.com (returns 404), so apt update failed immediately
instead of timing out. The actual root cause is that the public Canonical
mirror IPs (91.189.91.x / 91.189.92.x) are unreachable from inside docker
on GitHub Actions runners.

azure.archive.ubuntu.com is Microsoft's intra-Azure Ubuntu mirror, served
from the same Azure infra GHA runners live in. It hosts all bionic pockets
(main, updates, backports, security) and routes reliably from inside the
docker container.

Subject: [PATCH 42/43] enh: parallelize pytest with xdist and bump Mac/Win CI
 timeouts

- Add `pytest-xdist` and `filelock` deps on Mac, Win, Linux. Run pytest
  with `-n auto` to use all available cores.
- Wrap `_ensure_master` and `_ensure_master_ecc` with a per-path
  `FileLock`. `--random-image` is non-deterministic (regtest mode does
  not seed RNG), so two parallel workers racing on master creation
  would write divergent content and break golden-file comparisons.
- Bump Mac and Win `timeout-minutes` from 120 to 240. Even with xdist
  the Mac runner is slow (~100s per RS02 read test); the higher cap
  prevents the suite from being killed mid-run.

Subject: [PATCH 43/43] fix: merge golden-placeholder filter into --run-slow
 collection hook
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebasing onto the renamed framework.filter_empty_golden_placeholders
helper left two colliding pytest_collection_modifyitems definitions in
conftest.py — the second (slow-gate) def silently shadowed the first
(placeholder filter). Merge them into a single hook that calls the
filter before applying the slow-gate logic.
