Port ripwire natively to Windows (x64) using Clang with MSVC ABI, preserving
zero external runtime dependencies (linking only system kernel32, ws2_32,
advapi32, and shell32).
MECHANISM & ARCHITECTURE:
- Platform shim layer in src/infra/platform_compat.{h,cpp} and minimal POSIX
compatibility headers in src/infra/compat/ (sys/socket.h, unistd.h, poll.h,
sys/wait.h, etc.) routed via -include / /FI compiler options.
- Atomic cache rename via MoveFileExA (MOVEFILE_REPLACE_EXISTING) after closing
open file descriptors on Windows.
- Win32 Job Object subprocess runner in src/verbs_change.h for isolated child
process management, timeout enforcement, and asynchronous stdout capture.
- cmd.exe command-line adaptations: double-quoted git format strings to prevent
unintended pipe interpretation, and short-path generation (GetShortPathNameA)
for stream redirection without quotes (< shortPath).
- Socket safety: Winsock automatic initialization and explicit closesocket/CRT
handle separation in rw_close.
- Application manifest embedded in executables opting into longPathAware
(NTFS 32k path lengths) and UTF-8 active code page.
- Documentation in CONTRIBUTING.md and automated validation in ci.yml.
GATE & VALIDATIONS (Windows 11 x64):
- Doctor: ripwire.exe . --doctor -> 7/7 checks passed.
- Determinism: test/det-gate.sh passed (baseline + nesting-kind + width arm at 631 B).
- Retrieval accuracy: --eval-retrieval -> MRR 0.967 / recall@10 99.4% (3,038 symbols).
- Visualization: --html generates valid self-contained interactive force-directed graph.
- MCP Server: HTTP 2024-11-05 endpoint serves 31 tools and processes queries.

In @.github/workflows/ci.yml:
- Line 305: Update the Windows CI build step around the ripwire target to also
build ripwire_probe, either by specifying both targets or by removing the
single-target restriction. Preserve the existing build configuration while
ensuring failures in ripwire_probe compilation, linking, or manifest generation
fail the job.
- Around line 297-299: Update the CI workflow permissions to declare
workflow-level contents: read, and add persist-credentials: false to every
actions/checkout@v4 step that runs repository code, including the checkout
configured with fetch-depth: 0. Preserve the existing checkout behavior
otherwise.
In `@cmake/PortableFlags.cmake`:
- Line 39: Update the MSVC RIPWIRE_ARCH_FLAGS configuration to preserve correct
std::isfinite behavior by replacing /fp:fast with /fp:precise or adding the
appropriate compiler-specific finite-value preservation option. Keep the
existing optimization and warning flags unchanged.
- Around line 37-39: Update the MSVC branch that sets RIPWIRE_ARCH_FLAGS so
RIPWIRE_NATIVE=ON is honored for both MSVC and clang-cl builds, either by adding
the appropriate native ISA optimization flags or by failing during configuration
when native optimization cannot be provided; do not silently fall back to /O2.
In `@src/crossref.h`:
- Line 699: Protect the literal Git format placeholders from Windows cmd.exe
percent expansion in the commands used by gitCapture, gitoracle::walkGitPatch,
and renamemine. Apply the same safe command-path or cmd.exe-compatible escaping
at src/crossref.h:699, src/gitoracle.h:599, and src/renamemine.h:300 so Git
receives the intended --format fields unchanged.
In `@src/infra/jsonesc.h`:
- Around line 271-280: Update rw::shSingleQuote and the rw::compat::rw_popen
call path to prevent Windows cmd.exe from interpreting literal percent signs and
other command metacharacters inside arguments. Prefer a non-shell
argument-vector process API; otherwise implement and test Windows-specific
quoting that preserves paths such as C:\src\100%repo% when used by git commands.
In `@src/infra/platform_compat.cpp`:
- Line 339: Update rw_fflush around ::fflush(stream) to capture and return its
result immediately when it indicates failure, before rebuilding, reading, or
publishing the buffer; preserve the existing buffer-processing path for
successful flushes.
In `@src/infra/platform_compat.h`:
- Around line 208-216: Preserve Windows socket handles without narrowing them to
int: update the MCP listener’s socket() and accept() variables and the related
bind, listen, setsockopt, recv, send, and close calls to use SOCKET or another
pointer-width socket type, while keeping CRT file descriptors as int. Apply the
compatibility changes in rw_setsockopt in platform_compat.h and its
corresponding implementation in platform_compat.cpp, ensuring rw_close receives
and closes the full-width handle.
- Around line 230-232: Update the compatibility alias guard around format_string
to use __cpp_lib_format rather than __cpp_lib_format_ranges, so the alias is
defined only when the MSVC STL lacks the public std::format_string alias and
avoids redeclaration on implementations supporting P2508R1.
In `@src/ingest_cache.h`:
- Line 2143: Update the cache-frame variable returned by openCacheFrame() to be
non-const, then replace the const_cast call with direct prev.close().
In `@src/quality.h`:
- Around line 993-995: Update the cache-directory creation and validation flow
around mkdir and stat to use an explicit Windows DACL granting access only to
the current user, rather than relying on inherited permissions. Validate that
the resulting directory has the required restricted access control, and return
NUL when creation or validation fails; preserve the existing
successful-directory path.
In `@src/verbs_change.h`:
- Line 811: Update the CreateProcessA invocation around fullCmd to resolve the
trusted system cmd.exe path and pass that absolute path as lpApplicationName,

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win
Do not silently ignore RIPWIRE_NATIVE in MSVC-compatible builds.
CMake sets MSVC for both MSVC and clang-cl. Therefore, the leading if(MSVC) branch prevents RIPWIRE_NATIVE=ON from reaching the native branch. The build uses only /O2 and provides no equivalent native ISA optimization elsewhere. Add an MSVC native configuration or fail at configure time when this option cannot be honored.

🌐 Web query:
Microsoft _mkdir Windows mode parameter security descriptor inherited DACL documentation
💡 Result:
The C runtime library function _mkdir does not have a parameter for a security descriptor [1]. It is a wrapper that calls the Windows API function CreateDirectoryW (or CreateDirectoryA) with the lpSecurityAttributes parameter set to NULL [2][3]. Because _mkdir passes NULL as the security descriptor, the directory it creates will automatically inherit the Discretionary Access Control List (DACL) from its parent directory, provided the underlying file system supports security [4][5]. In Windows, when a new file or directory is created with a default security descriptor (by passing NULL), the system automatically handles the propagation of inheritable Access Control Entries (ACEs) from the parent object to the new child object [6][4][7]. If you require specific security settings or need to override the inherited DACL, you must use the Win32 API function CreateDirectory or CreateDirectoryEx, which accept a pointer to a SECURITY_ATTRIBUTES structure [5][2][8]. Passing an explicit security descriptor to these functions will override the default inheritance behavior [7]. top_results: [4][5][1][2][3][7]

Validate the Windows cache-directory access control.
::mkdir(d.c_str(), 0700) does not create a Windows DACL. The directory inherits the parent DACL, and stat accepts it without checking access control. If TEMP points to a shared location, another user can access the cache directory and its source-derived artifacts. Create the directory with an explicit DACL restricted to the current user, validate it, and return NUL if the check fails.

Thank you for this, and for the scale of it — native Windows with the MSVC ABI and no external dependencies is a serious piece of work, not a port sketch, and it clearly took real effort. I want to be straight with you rather than leave it sitting: the open question on this one is not technical. Adding a platform is a support commitment as much as a code change — every future PR, every release, and every bug report inherits it — and that is a scope decision I need to settle on our side before I can honestly review the code. It would be unfair to review it as though the answer were already yes. So: no timeline, and no promise. What I can commit to is that you get a real answer either way rather than an indefinite open PR, and that if the answer is no it will be for that reason and stated plainly, not left to expire. In the meantime, the Linux build runs unmodified under WSL2, and that is now documented in the README — which is a workaround, not an answer to what you built. Sorry to have left this quiet for as long as I did. |

I understand. Thank you for the clear answer. In the meantime, I'll try to keep my branch updated. |

I ended up just using the wsl2 binary directly from windows- in case anyone comes across this in the future. https://gist.github.com/matbeedotcom/e754922f39edeed297715d43382b9142 |

…Clang builtin CodeRabbit #127 finding 3985249663 (src/infra/strkern.h:436, +460/503/542/702) — VALID. The scalar twins findByte_scalar and find3_scalar are ALWAYS compiled and are the code that runs on a target with neither NEON nor AVX2; they used __builtin_ctzll, which MSVC does not provide. The project supports MSVC 19.36+ and the Windows port (PR #44) is pending, so the file would simply not have compiled there. The six vector sites go the same way for the same reason: MSVC compiles the AVX2 mirror under /arch:AVX2. All eight sites are now std::countr_zero( m ) with <bit> included. Same instruction on every toolchain that has one, and DEFINED at zero (returns the width) where the builtin is undefined — the change can only remove a footgun. Every site is already guarded by m != 0, so the value is unchanged at every one of them. BYTE-IDENTICAL, 12 of 12 proofs (build before vs after this commit, --no-cache): corpus --top-k=100000 --for=… --pack-task=… --grep=countr_zero ripwire 1,763,172 B same same same go 10,415,057 B same same same canyonraid48 7,229,007 B same same same GATE: test/strkerncheck.sh gains a SOURCE arm — 0 __builtin_ on a code line, >= 8 std::countr_zero( sites, <bit> included. It is a source arm on purpose: the only compiler on this box accepts both spellings, so no local build can tell them apart. CAN GO RED — observed firing ("uses 1 GCC/Clang-only __builtin_") before the arm was taught to skip comment lines. strkerncheck.sh: PASS — 19/19 assertions under full G1 sanitizers, NEON non-vacuity, -DSTRKERN_MUTATE=1 red as designed, Rosetta x86_64/AVX2 arms 3 and 3b both green.

…e the bytes were not, and six legends asked six different questions about rows Ten findings from the second review of #214, all reproduced against ff8d77a before the fix and all the confirmed ones red in a gate first. THE <tests> SECTION CUT WHERE THE BYTES WERE NOT. --pack-task's tests section is byte-budgeted, and E1 had it GROUP first and hand the group rows to the generic list cutter under a per-row byte cap whose estimate was `attrs + 48 + Σ( path + 1 )` computed on UNESCAPED path bytes. A corpus whose test paths hold '&' or '<' renders wider than that admits; packTaskListSection breaks at the FIRST over-budget entry, so the whole tail of the section went with it — run= singles included. Measured on a matched pair of ten-test fixtures differing in exactly one byte per name ('&' against '_') at --token-budget=1440: the control named 5 files, the '&' fixture named NONE. The section now cuts over its own grouped, ESCAPED rendering (packTaskTestsSection): the largest PREFIX whose rendered <tests> body fits the budget, found by bisection, which is exact because the rendered size is monotone in the prefix length (extending the prefix appends a row or extends the last group by `,path`, and the two-member <g> that replaces a one-member single is strictly wider). Chosen over the simpler cut-then-group — also safe, since grouping only shrinks — because cutting over the SINGLE rows' bytes then spends fewer of them: 2 files where grouping-first served 5. Over budgets 1440..1860 the new cut names 6..11 files against the old 5..11, and the '&' fixture never empties. RocksDB, --pack-task="change WriteBatch::Put" at the default 6,000-token budget: <tests shown="55" total="109"> (11,993 -> 12,490 B), where the pre-E1 bundle named 28. maxGroupBytes, its 48-byte constant, PackTaskSection's keptUnits/totalUnits and packTaskListSection's unitsPerEntry are all GONE with the estimate that needed them — one entry, one test file, on both sides of the cut — and with them the groupCap==0 "never split" degenerate the review flagged as plausible. Gate: testrowruncheck arm 13. SIX LEGENDS ASKED SIX DIFFERENT QUESTIONS ABOUT ROWS. The run-hint clause is a rule ABOUT rows (~180 B) and eight legends splice it. Each asked its own question: "is the rendered string empty", "does the document contain `<tests `", nothing at all. Two were wrong. partition.h grepped each slice's RENDERED bytes, so a bundle whose <bodies> CDATA quotes the literal text of the element — any source file that WRITES it does — charged the clause with zero rows (repro: a two-file corpus with no test at all whose one body prints `<tests n="%d">`, --pack-task="write_report" --partition=2). prcontext.h had the same mistake in its first fix, string-matching `<test p="`/`<g ` over the body. And --handoff and --flags --flip spliced it unconditionally — --handoff is byte-budgeted with heuristic rows dropped tail-first, so a packet with <tests n="0"> could evict a real row to pay for it. The seam that renders the rows is the only thing that KNOWS how many there are, so it returns the count with them (testmap.h JoinedTestRows) and all eight ask that one count through runHintClauseIfRows( testFilesRendered ). --pr-context carries it per trim level in PrTrimRender; packTaskBundleText reports its section's kept count to partition.h. Gates: testrowruncheck arms 14 and 15. --test-gate's clause additionally stopped riding an untested-only report, which is the same rule applied where it was already local. A SILENT EMPTY BODY. prRenderLevel returned "" on an open_memstream failure with NO alert, and the unbudgeted --pr-context path had just been routed through it: the document would have shipped legend, root and closing tag around an empty body claiming truncated="none". Every such render now goes through ONE seam (infra/emit.h rw::renderToString, the shape packtask.h already had) that reports the failure; packtask.h's own wrapper and mcpverbs.h's captureXml were folded into it in the same commit, and captureXml now alerts, which its copy never did. Both --pr-context exits fall back to streaming the level straight to `out` — complete, correct bytes, a modelled estimate, and a DEGRADED_PATH_ALERT saying which, which is serialize.h's ChargedSection degrade contract. , IS A PROMISE THE FORMAT CANNOT KEEP. A ',' inside a grouped path was spelled ,, and every XML parser undoes an entity BEFORE a consumer splits p= on the delimiter, so n= would disagree with what the reader counts; the text twin had no escape at all. A path containing ',' is now never grouped — it is served as a single row — which is right in all three dialects at once, and the legend says so instead of describing an escape. THE LEGEND AND THE EMITTER DISAGREED. <tests shown= total=> counts test FILES, while the bundle legend said "shown=rows kept, total=rows that qualified" — observed shown="8" total="8" over 3 rendered rows. Said in the row-gated clause rather than the always-on bundle legend, which is charged against the ceiling it describes: unconditional it put packtaskcheck's 2,000-token arm 5,620 B over a 5,428 B ceiling (measured). The MCP twins got the same fact: situational_awareness and explore return bare JSON with no legend of any kind, so their tool descriptions now carry the row shape (one wording, spliced twice). NINE GATES, NINE READERS. Every gate that asserts over these rows had its own: `grep -oE '"tests_to_run":\[[^]]*\]'` stops at the first ']', which since E1 is the end of the FIRST group's path array — testrowruncheck arms 3, 5 and 9 were asserting over two and a half rows and passing vacuously; receiptpostcheck, rootrelemitcheck ARM 6, impactpartitioncheck and selectorchaincheck read the single rows only; rootrelemitcheck's text reader took $1 of a line that on a group line is "[hops=1]". They all want the same thing — the files named, in emitted order — so they now all ask test/testrowpaths.py, one reader for three dialects and both row shapes, which qualifies a <g> row by run_unknown="1" so --flags' own <g> gate row is never read as a test group. Two more gate defects fell out: arm 7 read `<g n="` for a --flags gate row spelled `<gate name="`, so it skipped on every fixture including one that has a gate, and the arm-0 census regex did not know the seam's new name. Pins moved, each with the measured number. testgatelegendbudgetcheck 2,900 -> 3,000 (measured 2,957): two facts a consumer of a <g> row cannot do without, both in the row-gated clause, so a zero-row report still pays nothing. mcpmanifestcheck 42,384 -> 42,800 (measured 42,777): one 207-byte clause in two tool descriptions — NOT the L7 case that file declines, because that one described an ARGUMENT the schema already renders, and this describes a RESPONSE two legend-less JSON answers cannot state anywhere else. printf_parity.manifest: pack_task re-pinned (UPDATE_GOLDEN=1, "moved={pack_task}, 41 unchanged"). Two more table pins the change moved, both re-derived rather than bumped. fixedbufsweep's fixed-buffer census: packtask.h's `open` buffer row 2 -> 3 call sites, with the third site's own arithmetic written out (packTaskTestsSection's tag is the LITERAL 'tests', no %.*s at all, so the format is a fixed 35 B plus two %zu at 20 digits and one %d — worst case 76 B + NUL against 160, the widest margin of the three) and the first site's caller vocabulary corrected, since 'tests' no longer reaches packTaskListSection; EXPECTED calls/mentions/sites 218/322/218 -> 219/323/219. And the asan tree was rebuilt after the last src edit, so g1freshcheck stops reading a binary older than src/mcpverbs.h. Red first, against a build of ff8d77a: testrowruncheck (13) "control names 5 file(s), the '&' fixture names NONE"; (14) "--handoff(0 rows, clause present) --flags --flip=FEATURE_ZETA(0 rows, clause present)"; (15) "the partitioned bundle charges the run-hint clause for a body that merely QUOTES '<tests ' (zero rows)". All green after. --quality-delta gating="0" after acking ten rows BY SYMBOL through the binary (writeFlipHeader's one added parameter; renderToString against serialize.h's chargeSection, which is the est_tokens family's FAULT-INJECTABLE buffer and cannot route through a plain open_memstream seam without deleting the only reachable degrade path estchargecheck has; six churn=self rows that are this lane's own footprint across the item's two review rounds). ASan+LSan on testrowruncheck, prcontextcheck, packtaskcheck, partitioncheck, handoffcheck, flipcheck and mcpcontractcheck: 0 reports. Determinism and xmllint re-checked on --pr-context, --affected, --test-gate, --handoff and --pack-task. Full suite, python3 test/pargates.py . ./build/ripwire -j 6: "gates=627 pass=625 skip=2 fail=0 wall=820.6s", ALL PASS, exit 0 — the two skips are the environmental argvdiffcheck (no RIPWIRE_BASE) and editchecknotecheck (no RIPWIRE_BASE_BIN).

Thanks for documenting the WSL2 workaround. I tested the current release path from a Windows host with WSL2 and Ubuntu 24.04.4 LTS. Observed:
This is not a request to duplicate the native-port work in this PR. It is installation and integration evidence from a real Windows consumer. Once native Windows support is accepted, a Windows release asset/installer would remove the remaining integration friction; for the interim, a short documented WSL-to-PowerShell wrapper recipe could help users whose tools expect |

…itter deleted, and four comments named things that are not there ONE LEFTOVER FROM THE REVIEW OF 6621370, and four doc nits in the same commit. THE COMPACT <g> TERM DID NOT SAY WHAT THE FULL CLAUSE SAYS. 6621370 rewrote testmap.h's kRunHintLegendClause: a path holding ',' is never grouped (the escape is gone, because an XML parser undoes an entity BEFORE a consumer splits p= on the delimiter), and a shown=/total= over these rows counts test FILES. Its compact twin — compactlegend.h's <g> term, the compact dialect's ONLY reading of <g> — was left saying "every path verbatim (, a comma)" and never carried the counts-FILES rule at all. A reader holding only the compact legend was told to undo an entity that is not there, and on a comma-path corpus `--affected --legend=compact` contradicted the full legend about what the pair counts. The term now states both facts in the FULL CLAUSE'S OWN WORDS. WHY NOT ONE CONSTANT. The task asked for one constant if practical; it is not. kRunHintLegendClause is 350+ B of prose and the compact table is charged per verb — the compact dialect exists precisely to RE-SPELL rather than quote, which is the whole reason it is smaller. So the two are pinned against each other instead: test/compactlegendcheck.sh arm (R) reads the phrases it requires OUT OF kRunHintLegendClause and fails if either wording drops one, or promises , again, or if the compact term loses its `true, "g"` element qualifier and starts charging every single-row document. Add a fact to the full clause and the arm fails until the compact term carries it too. RED FIRST. Arm (R) reads source, not output, so its red is shown against 6621370's src/: the parent's compact term states none of `a path holding ','`, `splits into exactly n=`, `counts test FILES`, and still promises `,`. Green on this tree. PINS: NONE MOVE — measured, not assumed. The term goes 99 -> 194 B, and it is present-only and qualified to <g>, so it is charged only on a document that carries a <g> run_unknown= row. On this tree and on every gate fixture every harness has a runner, so nothing groups and the term never emits. Verified by building 6621370 in a scratch worktree and running compactlegendcheck, testgatelegendbudgetcheck and packtaskcheck against BOTH binaries from this working tree: every byte number in all three is identical (testgate legend 2957 B <= 3000, pack-task compact 865 B <= 880), all three ALL PASS on both. The real cost is measured on a purpose-built fixture of six runner-less tests that does group: `--affected --legend=compact` 501 -> 596 B, the +95 being exactly this term. DOC NITS. * src/prcontext.h:611 and :929 named prBodyHasTestRow, the string-matching predicate 6621370 DELETED. They now name what actually decides it: the COUNT the level's own emitter reported (PrTrimRender::testFiles), which writeHead takes. * test/testrowpaths.py's docstring and the CHANGELOG said NINE gates had grown their own reader. Six read the PATHS and are converted (affectedcheck, impactpartitioncheck, receiptpostcheck, rootrelemitcheck, selectorchaincheck, testrowruncheck); both now name them. Two more gates read these rows and are NOT converted, and the docstring now says why: listingpagingcheck sums n= over the <g> rows and w3fixlegendcheck counts path occurrences on a --situ line — neither asks for the paths, both were made group-aware in place, and routing a COUNT through a path reader would only add a dialect hop. * test/mcpmanifestcheck.sh's re-anchor comment read "+416 B, EXACTLY the one 207-byte clause spliced into the TWO tool descriptions" — 207 x 2 is 414. The missing 2 B are the two separator spaces: each description previously ended at '.' and now ends '. ' before the splice, so it is 2 x 208. The CHANGELOG said the same thing and is corrected with it. The ceiling itself (42,800) and the measured 42,777 are unchanged and were right. The ack ledger is untouched by this commit. Note on the ten acks 6621370 wrote: eight are keyed by symbol (cid=); the other two — `duplication f10ce50bdc680d80` and `new-clone-of-reused-helper f10ce50bdc680d80` — carry no cid because those two kinds key on the clone MEMBER-SET hash. They are group-scoped by that kind's design, not by an omission: a clone finding is a property of the group, so there is no single symbol to name. Gates: compactlegendcheck (ALL PASS, arm (R) red on 6621370's src/), testgatelegendbudgetcheck (ALL PASS), packtaskcheck (ALL PASS), manifestcheck, docs/gatecount_build.py --check (613), docs/limits_build.py --check.

…ing, and the no-throw copy threw
Six findings from one review, every one of them a surface that was silently wrong rather
than loudly broken.
--pr-context PRINTED A WRONG est_tokens WITH NO DISCLOSURE. When a trim level's measurement
render fails, prRenderLevel returns an EMPTY body; pickPrTrimLevel priced that empty body, the
price fit, and the ladder broke at level 0 — while writePrContext correctly streamed the
complete untrimmed floor through emitFiles( out, kPrTrims[0], nullptr ). The only signal was
DEGRADED_PATH_ALERT, which src/infra/Diagnostics.h compiles to `do {} while (0)` under NDEBUG,
so the binary a user installs printed a modelled number with nothing at all saying so
(non-negotiable #3). The BYTES were never the defect and do not move: cutting answer rows
because a measurement buffer failed would let a cap decide the content, which is the one thing
a cap may never do. The fact goes where this class of fact already lives — truncated= now
carries ";est-unmeasured", re-priced with the label in place (the label lengthens the root tag),
and the legend defines it in budget-floor-exceeded's own voice.
THE CHARGE IS READ OFF THE LABEL, not off a boolean beside it. prPriceDocument decides the
clause from the truncated= value it is already handed, so ONE condition decides both the priced
legend and the delivered legend and they cannot drift apart; and the two conditional clauses now
arrive as a named PrLegendClauses{ runHint, estUnmeasured } rather than two bare bools, because
`prLegendText( escBase, unindexed, true, false )` says nothing at its call site about which
clause is which. Both readings came out of --quality-delta: threading a seventh parameter into
prPriceDocument and a fourth into prLegendText took the range form to gating="2" (a params row
from minor to major, and an api-surface contract change that invalidated a standing ack). The
range form is gating="0" now with NO new ack — the findings are gone rather than suppressed.
THE DEFINITION IS LABEL-GATED, which the gate found for me. Spliced unconditionally, the ~390 B
clause cost test/defaultceilingcheck.sh's fixture its entire remaining headroom: that 120-file
tree prices at 7,989 of the 8,000 default — 11 tokens spare, as E1 measured when it gated the
run-hint clause for the same reason — and went to 8,037, over budget on a document with nothing
unmeasured about it. So kPrEstUnmeasuredLegendClause rides exactly the document that carries the
label, decided by the fact the ladder recorded (PrTrimRender::rendered) and never by a search of
the rendered bytes; the pricer charges its size on the same fact, so the priced legend and the
delivered legend cannot disagree. A healthy document is byte-identical to before (est_tokens
7,989, re-measured) and prcontextcheck (F-legend) holds it that way.
THE LABEL CROSSED prBudgetTail's BUFFER. test/fixedbufsweep.sh had this buffer at 248 B of
tail[256] — "SEVEN bytes of margin ... one more attribute crosses it" — and ';est-unmeasured'
is 15 more and CAN ride beside ';budget-floor-exceeded' (a small --max-tokens puts even the
unmeasured empty-body envelope over budget). Worst case 88 lit + 90 digits + 85 label = 263 B,
so tail[320], 56 B of margin, and the sweep's row moves in this commit with the recomputed
number. rw::formatTo was not what had been saving it: it truncates SILENTLY and its return is
not read there, so an overrun would have dropped the closing quote of truncated=" and shipped a
malformed root — a G4 breach with no diagnostic.
renderToString's NO-THROW CONTRACT HAD A THROWING LAST STATEMENT. out.text.assign( buf, sz ) is
the one allocation on the success path and it sat outside the handler, so a std::bad_alloc from
it escaped a function documented to ALERT a failure and return ok == false, and jumped the
std::free( buf ) two lines below on the way out — leaking the memstream buffer. Caught in its
own handler rather than one around the whole body, because the two failures need different
cleanup (the emitter's throw owns an OPEN stream; by this point only buf is left), with its own
alert literal, and control falls THROUGH to the single free() so buf is released exactly once on
every path.
THE SHARED ROW READER'S MALFORMED-FIELD DETECTOR HAD A HOLE OF ITS OWN SPECIES.
test/testrowpaths.py found "tests_to_run" and then scanned arbitrarily far forward for a '[', so
{"tests_to_run":null,"other":[{"p":"ghost.cpp"}]} sliced the NEXT field's array and returned
ghost.cpp at exit 0 — a foreign field's paths served as this field's answer, where the docstring
already promised a TestRowParseError. The value is read adjacently now: past the key, a ':',
optional whitespace, then '[' or raise.
AND TWO PATH READERS HAD NEVER BEEN CONVERTED. The census over test/ for the four shapes the
shared reader replaced found test/affectedcheck.sh's tset() — inside the very file the reader's
docstring names among those it converted, so that claim was false — splitting EVERY row's p= on
',' including a single row's, which turns a comma-bearing path (never grouped, by testmap.h's
refusal) into two names that name nothing; and test/testgatecheck.sh's tset() matching `<t p=`
singles only, which returns the EMPTY set on a two-runner-less-test fixture where the shared
reader returns both paths. Both route through the shared reader now, and the docstring records
the census. Every other hit counts rows (listingpagingcheck, w3fixlegendcheck, testgatepagecheck
— all group-aware in place) or pins one exact row spelling with a regex that fails loudly;
deeptailcheck's `<t p=` rows are --for's tail listing, a different element sharing the tag.
Two documentation drifts beside them: skills/ripwire-mcp/SKILL.md claimed `p` for
situational_awareness, which emits `test` (src/mcp.h's kTestRowJsonShapeClause states the split
and the binary is the authority), and bench/arb/run_arb.py decoded a , the seam stopped
emitting on 2026-09-13 while decoding NONE of the entities it does emit — so a path holding '&'
was scored against a file name that does not exist. Both row shapes there share one decode now.
GATES, all red on the parent commit and green after:
* test/prcontextcheck.sh (F-legend)(F5)(F6) — est-unmeasured in truncated= on the degraded
root, the complete body still served, and the legend defining the term. RED: the degraded
root printed truncated="none" while pricing an empty body, and no legend defined the label.
* test/prcontextcheck.sh arm (G) — INFRA_FAULT_RENDER_COPY_THROW, the emitter switch's twin,
injected immediately before the assign. RED: "produced no DEGRADED_PATH_ALERT on a binary
that PROVED it can emit one". Honest in both flavours, mirroring arm (F): the switch and the
alert live only on the non-NDEBUG build, so the plain leg proves the degrade and the NDEBUG
leg asserts the verb is intact and no false disclosure appears. The est-unmeasured LEGEND
definition is asserted on EVERY flavour, which is the point of moving the disclosure off the
alert.
* test/testrowruncheck.sh arm 17 — every non-array tests_to_run value is exit 2 in both paths
and jsonlist, with a well-formed array and JSON whitespace as controls. RED: five documents
at rc=0, three of them serving ghost.cpp.
Suite: 628 gates, 626 pass, 0 fail, 2 environmental skips (argvdiffcheck and editchecknotecheck,
both wanting a reference binary), tree_writes=0. ASan/LSan clean on --pr-context healthy and on
both injected degrades.
Pins moved, two, both in test/fixedbufsweep.sh and both with the measured recomputation in the
same commit: the src/prcontext.h tail TABLE row 256 -> 320 (worst case 248 -> 263 B, margin 7 ->
56), and EXPECTED mentions 323 -> 324 — re-read from the diff, not accepted from the delta: the
one added line is the COMMENT explaining that growth, which names formatTo. calls, sites, rows
and widthforms are unchanged at 219/219/92/0. No legend or byte pin moved.

…ble disclosure once per row The defect. A tests-to-run row with no derivable runner said so on the row (run_unknown="1" in XML, "run_unknown":true in JSON, "(run: not derivable)" in --situ's text). On a corpus where almost no harness has a runner that is the same 16 or 23 bytes repeated per row: rocksdb's --affected=db/write_batch.cc listed 127 tests, 126 runner-less, and spent 2,016 B of XML and 2,898 B of text saying one thing 126 times. The disclosure is right (an absence is not a disclosure, M21(b)); its per-row placement was the cost. E1 / A4-2 in the output-routing loop, owner call 2026-09-12: say it once per GROUP. The fix. Rows come in evidence order (changed, partner, hops asc, path), so runner-less rows whose per-row attributes are byte-equal are served as ONE row, emitted where the first member stood: <g hops="2" n="17" p="a,b,c" run_unknown="1"/> (JSON: "p"/"test" becomes an array beside "n"; text: "[hops=2] (17): a, b, c (run: not derivable)"). Rows with a runner stay single; a group of one stays a <t>; a comma in an XML path is &redhat-et#44; (columnar.h's precedent); every path is kept verbatim. All twelve emitters (--affected, --exercises, --test-gate XML/JSON, --situ, --pr-context, --handoff, --flags --flip, --pack-task XML/JSON, the MCP situational_awareness twin, the edit receipt) render through one seam in testmap.h (partitionTestRows / testRowsRendered / testRowsJoined); the ""-means-not-derivable test stays in runHint alone. kRunHintLegendClause defines <g> in the same sentence ("a <t> or <g> row carries one or the other, never neither"); the compact dialect gains two present-only terms (run_unknown=, and the <g> reading qualified to that element). --affected, --exercises, --pack-task and the partitioned outer legend splice the clause rows-gated, so a zero-row answer pays nothing. --pack-task's byte-budgeted tests section caps a group at its own budget (an uncapped group is one ~3 KB row its 10% quota cannot hold, measured shown="0") and its shown=/total= and JSON tests_total/tests_kept keep counting FILES. Measured (rocksdb, same cache, same commit, wc -c): --affected=db/write_batch.cc 10,668 -> 6,839 B; --test-gate=db/write_batch.cc 13,242 -> 9,594 B, its JSON 11,055 -> 7,121 B; --situ=db/write_batch.cc 11,769 -> 7,313 B; 7 <g> rows replace 124 single rows; the residual spent on the disclosure is 144 B (XML) and 207 B (text) per list. --pack-task names 54 of 109 tests where it named 28 (12,347 B vs 11,993). On this tree every harness has a runner, so nothing groups; the deltas are the legend (affected +371 B rows-gated, test-gate +180 B, situ +79 B, JSON and pack-task unchanged). Gates. test/testrowruncheck.sh: XROW/JROW learn the <g> and array shapes, the arm-0 census moves to the seam's call sites (mcpedit.h joins it), and arm 12 proves the multiset of paths in every dialect on a fixture with three hop groups and a runner row in the middle of one (RED on the previous binary: "expected >=3 <g> rows at distinct hops=, got hops=[]" x2 and "expected >=3 group lines, got 0"; GREEN after). Consumers taught the row: affectedcheck tset(), listingpagingcheck (C)/(D), w3fixlegendcheck's [2] count, bench/arb/run_arb.py. Pins moved with the measured number: testgatelegendbudgetcheck 2720 -> 2900 (measured 2843; the +180 B <g> sentence in the row-gated clause), compactlegendcheck ripwire.pack-task/v1 820 -> 880 (measured 865; the fixture's runner-less rows now define run_unknown= in compact), and the printf-parity manifest re-pinned for pack_task alone (UPDATE_GOLDEN=1, diff reviewed: one label). Determinism (diff -q) and xmllint on every changed verb; ASan on the gate fixtures and the rocksdb list; --quality-delta gating="0" after the seam took the two real rows (runExercises complexity, the test-gate twins' duplication) and --quality-ack --ack-only=short-horizon-churn took the family's in-window churn.
