Observed on 0.10.8/macOS: 2233 consecutive failed workers over 4h43m, ~8/min, every one dying at the same worker-side coordination seal. Read queries stayed healthy throughout, so nothing surfaced to the user while no project could be indexed at all. #937 deliberately leaves the baseline uncommitted on a failed reindex so the change is retried rather than lost. That guarantee is kept; what changes is the cadence. Each consecutive hard failure doubles the delay, capped at five minutes, taking a permanently failing project from ~480 attempts/hour to ~12 while still recovering on its own once the cause clears. Busy-skip (rc > 0) and success paths are untouched. The delay arithmetic is a pure exported helper so it is unit-testable without a clock. watcher.index.err now carries rc and the consecutive- failure count, and a distinct watcher.index.sustained_failure names a project whose failures are clearly not transient. Note: itoa_buf returns a single shared per-thread buffer, so the two-value log line uses local buffers rather than two itoa_buf calls.

Deleting the streak reset, or widening the sustained-failure comparison, left all 7788 tests green: the index_backoff_* tests cover the delay arithmetic, and nothing covered the counter that selects which delay applies. A streak that never increments silently degrades the backoff to the unbounded retry it exists to prevent. Adds cbm_watcher_index_failure_count(), alongside the existing cbm_watcher_watch_count() in watcher.h's "Introspection (for testing)" section, and a test that drives a real git repo through fail/fail/succeed on the failing_index_callback seam already used by the #937 test, asserting the streak goes 0 -> 1 -> 2 -> 0. Verified by mutation: removing the reset turns it red at the reset assertion while every index_backoff_* test stays green. The delay-GATING half stays uncovered on purpose. Every integration test calls cbm_watcher_touch first, which zeroes next_poll_ns, so whether the scheduler honours the computed deadline is unobservable without an injectable clock the watcher does not have. That harness is a larger change than this fix. F3 (minor) — cbm_watcher_index_backoff_ms was non-monotonic for an interval above the ceiling: zero failures returned the interval, one failure returned the smaller ceiling. Unreachable today (POLL_MAX_MS < the ceiling), but the function is exported, so the clamp is now a floor as well as a cap and backing off can never schedule sooner than the project's own cadence. F2 (minor) needed no code change: a busy-skip following an unresolved failure streak keeps the backed-off delay, which is deliberate — only a success clears the streak, and treating rc > 0 as recovery would let a project alternating fail/busy never back off at all. The PR description's over-strong "busy-skip is behaviourally unchanged" claim is corrected there.

MAJOR — the delay wire-up had no coverage, and the reason given for that was wrong. Round 1 claimed the gating half was "structurally unobservable without an injectable clock". It is not. cbm_watcher_touch zeroes next_poll_ns, so a wire-up that never sets a deadline leaves it at zero and the callback fires on every poll: simply NOT calling touch between polls observes gating deterministically, no clock involved. Only the delay's MAGNITUDE needs one. watcher_index_failure_backoff_gates_repolling_issue2015 covers it — one hard failure, then five polls without touch asserting no re-fork, then a touch proving the retry still gets through (so the test cannot pass by observing a dead watcher). Mutation-verified: deleting the wire-up yields "failing_index_calls == 6, expected 1". MINOR — round 1's F1 was half-fixed. Of the two single-token mutations that finding named, only the streak reset was covered; widening the sustained-failure "==" to ">=" still passed. watcher_sustained_failure_logs_ once_issue2015 drives 14 consecutive failures through a cbm_log_set_sink and asserts exactly one emission. Mutation-verified: ">=" yields "sustained_log_hits == 5, expected 1". All three mutations F1 named are now demonstrated caught rather than argued about: reset removal (round 1), wire-up deletion, and the "==" widening. MINOR — cbm_watcher_index_failure_count reads index_failures under projects_lock while poll_project writes it lock-free from a state snapshot. That is the discipline every other per-project field here already follows, so this documents the visibility contract rather than making one field atomic in isolation: the accessor is a diagnostic and test seam, not a synchronisation point, and must not carry scheduling decisions without atomic accessors first. MINOR — watcher.h still described the pre-F3 backoff contract. It now states the clamp is a floor as well as a cap, why the floor exists for an exported function whose reachable inputs cannot currently hit it, and that negative inputs are treated as zero. Still uncovered, now stated precisely rather than hand-waved: the delay's MAGNITUDE. Nothing asserts that ten failures produce a five-minute delay rather than a five-second one. Gating is proven; the numbers are not, and that does need a controllable clock.

Two of the three findings are corrections to inaccurate statements the round-2 commit (61ccd905) introduced. The gating test's framing was overstated, and this time the overstatement was measured rather than argued. Replacing the backoff call with the pre-change `ctx->now + interval_ms * US_PER_MS` leaves the watcher suite green at 82/82: the index_backoff_* tests pass because they exercise the pure function directly, which the reverted scheduler no longer calls, and the streak tests pass because the counter is untouched. So no test in this suite fails when this change's behaviour is removed. The test now records that, with the figure, instead of claiming it demonstrates the backoff. It is a regression guard on a deadline being assigned at all — real, but narrower than round 2 said. Closing that gap needs either a controllable clock or a further accessor exposing next_poll_ns. Both were judged out of scope: a third exported symbol purely for testing, on a change already carrying two, is the API widening earlier rounds flagged. The gap is recorded in the test, the PR description and the round-3 note rather than papered over. The memory-visibility comment claimed index_failures follows "the same discipline every other per-project field in this struct already follows". That is false: active_git is serialized by projects_lock and registered is an atomic_bool. Narrowed to the poll-mutated fields, which are now enumerated. The round-2 decision to document rather than lock still stands — the panel verified the underlying premise — but it was resting on an overbroad claim. watcher.h said the delay "doubles up to a fixed ceiling", which skips the shift cap: the delay plateaus at interval_ms << INDEX_FAIL_SHIFT_MAX, and that reaches the ceiling only for interval_ms >= 4688 ms. Every interval this watcher generates is >= POLL_BASE_MS so the ceiling is always reached in practice, but the function is exported and a caller may pass less.

It writes URL(string: "https://…")! instead, and the literal then sits two levels below the argument list: past the trailing "!", which the grammar models as a postfix_expression, and inside the constructor's own value_arguments. extract_url_or_topic_arg saw only the outer node and gave up, so the URL never reached the service-pattern table and no Route node formed. That is the shape issue #1892 reported from a real project — reaching a bare string argument was only the layer underneath it. swift_unwrap_url_constructor() steps past both wrappers. It unwraps only URL, URLComponents and URLRequest, so any other constructor keeps its own meaning and the outer call does not borrow the inner call's string. A non-literal argument such as URL(string: base + path) falls through to the ordinary handling unchanged. The value_argument unwrap added for the bare-string case is now swift_argument_value(), because the nested argument list needs the same step and the code was identical.

Conservatively reconcile remapped definitions to recover hidden classes, structs, enums, free functions, and inline methods while suppressing matching base-class phantom callables. Add focused regression coverage for supported suffixes, ordinary all-caps negative controls, candidate limits, comments, strings, raw strings, overlong names, explicit define priority, and C/C++ extraction. Rebase onto main 92abefa3 and route the temporary superseded-definition bitmap through the extraction memory class to comply with the current allocation contract. Preserve the error-region dropped counter initialization.

Check repo_path exists and contains source files." The writer's temp -> final rename in publish_writer_output() returned a bare ERR_WRITE_FAILED. #1628 taught cbm_rename_replace() to translate the platform error into errno so callers could report why, and wired up the stage -> final rename in pipeline.c. This is the other rename on that path, and it is the one that runs first. Preserve errno across the cleanup in every publish error branch. That includes cbm_writer_open(), where the cleanup unlinks a file that was never created: without the save it leaves ENOENT behind, so a directory that denied the create is reported as a missing path — the #1620 case, stated wrongly. Read the value in graph_buffer.c before the profiling macro can clobber it, and report gbuf.dump_failed with the return code and that errno. A sticky append failure clears errno rather than attach a reason it does not have, and the field is omitted when there is none. No logging is added inside internal/cbm/, which has none today. Tests cover both halves: the dump reports a failure instead of a summary, the writer names its truncation reason, and the publish rename's errno survives a cleanup that itself fails.

Its CI lint was green on 2026-09-09. On 2026-09-19 the memwaste merge cut this file's raw sites and ratcheted the baseline down to 814, so by the time #1723 landed its green was measured against a rule that no longer existed. The linter is right and the merge-result check that let it through was incomplete: it built and ran the suites and did not run the linter. It does now. The fix is not cbm_free. The three strings come from cbm_mcp_get_string_arg and resolved_repo_path_from_project_arg and are raw heap memory, released raw by every other path in the function; routing three of them through the core would free raw memory through the accounting layer. The actual defect is that the function had 41 raw free() calls of the same three arguments across a dozen early returns, and #1723 added one more block in the same shape. One helper, index_args_free(repo_path, mode_str, name_override), now replaces twelve of those blocks. free(NULL) is a no-op, so the one path where repo_path is still NULL passes NULL. On the cross-repo branch mode_str used to be freed before handle_cross_repo_mode and the other two after it; mode_str is neither passed to nor read by that call, so releasing all three after it is not observable. Five sites on the normal-completion path are left as they were: they free the strings at different points as ownership is handed to the pipeline, and collapsing them would change that order for no gain. Raw sites in this file: 817 -> 785. The baseline follows the improvement, 814 -> 785, as the linter asks; it can only tighten. Build: clean, -Werror, ASan/UBSan. mcp cli daemon_application: 692 passed, 4 skipped, 0 failed -- index_repository_honors_allowed_root, which runs through a replaced early return, included.

"isError":true} Second collision from the #1723 merge (92abefa3), and the same kind as the first. #1723 made an index worker refuse any request that does not carry `_cbm_index_policy`: a worker never resolves the resource policy from config or environment, the supervisor does and sends it along. tests/test_worker_session_scope.sh, added on 2026-09-06 by a08b9ecb, plays the supervisor by hand -- it runs `cli --index-worker index_repository '{"repo_path":...,"mode":"fast"}'` directly -- and #1723's branch never contained that script, so its CI never ran the two together. The merge was textually clean and the result was wrong. It stayed hidden behind the lint failure the previous commit fixes, because the test stage only runs once lint is green. The worker is right and the script was incomplete: it now sends what the supervisor sends, both limits off, which is the default (`"index_max_files":"off","index_max_source_mb":"off"`, the same object tests/test_index_policy.c uses). The fail-closed case carries it too, so that a request without repo_path is still refused for its missing scope ("request workspace scope invalid") and not, by accident, for a missing policy. No assertion changed. RED, production binary built from this branch, script unmodified: worker did not index the admitted repository ... "missing or incomplete trusted worker policy" ... rc=1 GREEN: ok: index worker is scoped to the admitted request, not the daemon environment rc=0 On the failed CI run of this PR, 12 of the 13 red test jobs carry exactly that signature and nothing else. The 13th, test-windows-guards, is test_daemon_stability.py section_cold_storm ("secure CLI coordination could not be created (endpoint)", a racing cold start) -- a known nondeterministic guard, unrelated to either commit here. Step 6, which Step 5f's failure kept CI from reaching, passes locally: security-strings allow-list 4 passed, destructive-ordering contract PASS.

Deterministic resolution (O9). Two indexes of one kernel tree differed in 5,821 IMPORTS and 632 CALLS edges. Three order/load dependencies carried it: the `#include` target was the first by-name hit whose path ends with the include path — a bucket in worker merge order (include/linux/device.h vs tools/virtio/linux/device.h); the registry broke suffix_match score ties by bucket position; the LSP budget-share rule measured wall time. Include targets now prefer the File node, the least nested path, then the lexicographic path; registry ties prefer the least nested QN, then the smaller QN; the budget share is measured in thread CPU time like the budget itself. Two kernel indexes are now identical (8,529,723 nodes, 1,974,940 CALLS, zero churn), as are two elasticsearch indexes. Findability. search_graph's BM25 path honours the `label` filter and ranks an exact-name definition above test methods that repeat the token (15/15 probe queries). Coverage. The parse-coverage gap tree subtracts definitions the walker recovered inside an error region (multi-line only); kernel/sched/core.c reports 476 flagged lines instead of 7,674. Precision. Config-language callers (Makefile, CMake, YAML) no longer bind unique_name into code (kernel Makefile -> C CALLS 195 -> 0). JS-family token names ({}, 1, (x: T) => U) are not definitions; computed, quoted and escaped member keys stay (TypeScript 204 junk -> 0, 1,782 real names kept). Names are cut at their first line (elasticsearch YAML 8,306 -> 0); a comment inside an argument list is not an argument, so no Route node is named by a Java block comment; the wildcard route `/*` is still a route. HTML/Vue/Svelte/Astro embedded member calls stay unbound. Recall. A Python call through a self- or cls-rooted attribute keeps a specific unique_name member target (Django +751, elasticsearch +3,288 CALLS, no new callee names). Robustness. Edge properties never carry a split UTF-8 sequence (the 120-byte expression cut and the JSON escaper both trim a partial code point). CLI array flags accept a JSON-array literal. Cypher seeds a single-hop pattern from its selective end (kernel `MATCH (a)-[:CALLS]->(b) WHERE b.name = '_printk'`: execution limit -> 7.9 s).

It asks GitHub for the PR's file list. An earlier fix moved it off the .diff endpoint, which rejects PRs over 20k lines, onto the paginated pulls/files endpoint -- but that endpoint renders the diff server-side as well, and for a PR that regenerates a vendored parser it answers HTTP 422: Sorry, this diff is taking too long to generate. Observed on #2246 (a 42 MB sql/parser.c): `changes` red, therefore ci-ok red, for a reason that has nothing to do with the contribution. The compare endpoint fails the same way, so there is no API route to the file list for such a PR. Every grammar refresh would hit this. When the API call fails, the job now takes the list from git instead. The PR merge ref's first parent is the base, so a name-only diff across that one merge commit is exactly the PR's changed files. The fetch is depth 2 with --filter=blob:none into a bare repository under RUNNER_TEMP: commits and trees only, no blobs, nothing checked out and nothing from the PR executed. No new action, no new permission, and the API path and the classification regex are untouched, so ordinary PRs behave as before. A ::notice:: line records when the fallback was used. If the fetch fails too, the step exits non-zero and writes no output -- the gate fails closed, as it did before. Proof, by executing the workflow's own run block under `bash -eo pipefail` with a stub gh: API path, docs-only list rc 0 product=false fallback, real #2246 rc 0 product=true, the same five files `git diff --numstat` reports for the PR; 0.85 s, 188 KB fetched fallback, nonexistent merge ref rc 128 no output written Contract tests that read pr.yml -- security_gate_fail_closed, smoke_fixture_contract, windows_bundle_contract, venue_parity_contract -- pass. Not addressed here, noted for a follow-up: the classification pipes the list into `grep -q` under pipefail, which can report a match as a failure once the list outgrows the pipe buffer.

The classification was if printf '%s\n' "$FILES" | grep -qE '^(src/|internal/|...)'; then under the runner's `bash -eo pipefail`. grep -q exits on its first match; once the list is larger than the pipe buffer printf is still writing, dies of SIGPIPE, and pipefail turns the MATCH into a failed pipeline. The else branch then writes product=false, and pr-smoke and memwaste are skipped -- on exactly the PRs that change the most files. The previous commit's message flagged this as a follow-up; it is fixed here instead. The list now reaches grep through a here-string, so there is no pipe to break. The regex is unchanged. Proof, by executing the workflow's own run block under `bash -eo pipefail` with a stub gh, ten runs each: 849 KB list, first line src/a.c before: product=false 10/10 after: product=true 10/10 849 KB list, docs only product=false before and after small docs-only list product=false 422 fallback on the real #2246 product=true fallback, nonexistent merge ref rc 128, no output written It takes roughly 1,500 changed files to cross the buffer, which is why ordinary PRs never showed it.

Short ids fired inside unrelated words, and a service kind REPLACES the plain CALLS edge, so a false match both invents a service edge and deletes a real call: "gin." in plugin. -> route registration; any "/"-prefixed first argument then minted a Route node "nconf" in encryptionconfig -> CONFIGURES for every call into the package "tonic" in Monotonic -> gRPC; unparseable, so NO edge at all "express" in expression -> route registration "get_env" in get_envelope, get_environ -> CONFIGURES "dio" "surf" "curl" "resty" "phin" "hyper" "treq" "rocket" in studio, surface, curly, restyle, dolphin, hyperbolic, streq, rocketmq The rule (qn_hit_on_boundary; every occurrence of an id is tried, not only the first). A separator is any character that is not an ASCII letter or digit. before: start of string | separator | the id itself starts with a separator ("@trpc/server") | the id starts with an uppercase letter -- a capital opens a new CamelCase word whatever precedes it (AsyncHttpClient, IHttpClientFactory, NSURLSession) after: end of string | separator | the id itself ends in a separator ("gin.") | uppercase letter (GuzzleHttp, FeignClient, KafkaProducer) | digit (urllib2, Mint.HTTP2, amqp091-go) Rejected: a lowercase- or digit-initial id glued to a preceding letter or digit, and any id continued by a lowercase letter. Two deliberate differences from the upstream hunk: upstream's before-rule needed a GuzzleHttp table entry and would have dropped IHttpClientFactory and NSURLSession, and without the digit after-boundary urllib2 and amqp091-go stop matching. All three match on main today. No recall is traded for this. No boundary rule can tell "grequests" from "myrequests", so a library whose own name glues a prefix or suffix onto another id gets an explicit entry with the kind (and broker) it had on main -- 47 of them, found mechanically by running main's matcher and the new one over 173 candidate names and listing every one that went from a kind to NONE: HTTP grequests txrequests redaxios gaxios libcurl curlpp curlcpp hyperlocal guzzlehttp ASYNC aiokafka pykafka rskafka librdkafka rdkafkacpp aioamqp amqpstorm pamqp pyamqp amqprs amqpcpp pynats jnats aiomqtt amqtt hbmqtt umqtt mqttools emqtt rumqtt gomqtt libmosquitto mosquittopp pubsublite gocelery CONFIG wgetenv getenvb qgetenv dotenvx phpdotenv ROUTE_REG apiflask honox fasthttprouter GRAPHQL gqlparser gqlgenc aiogqlc Left at NONE on purpose: names that are not clients of the id they contain and were misclassified on main -- hypercorn, hyperlink, hyperopt, openresty, gqlalchemy, celeryconfig, kafkacat, gnatsd, pypubsub. One visible reclassification: hyperium/tonic was HTTP through "hyper" inside "hyperium" and is now gRPC through "tonic". RED, production reverted and the final tests kept: infrascan_service_pattern_match_rejects_ids_inside_words FAIL tests/test_infrascan.c:105: svc_case_mismatches(cases) == 28, expected 0 == 0 4 passed, 1 failed All 28 negatives mismatch on main. The 47 glued-library positives are RED the other way round: against the boundary rule without the entries. Each positive uses a name containing no second id, so it binds to its own entry -- "aiokafka.AIOKafkaProducer" would have passed through "KafkaProducer" and proven nothing. GREEN: infrascan 5, pipeline 281, parallel 74, extraction 350, edge_types_probe 59, route_canon 11, lang_contract 41, cross_repo 8, registry 64, mcp 318 (4 Windows-only skips). 0 failed. Effect on real code -- production binaries, main 92abefa3 against this change. main against main differs by 0 edges and 0 nodes on all three corpora, so every delta below is the change: django CONFIGURES 76 -> 74; both calls return as CALLS (geom.get_envelope, WSGIRequestHandler.get_environ) typescript CONFIGURES 12,026 -> 12,024; one bogus Route "/*type*/" gone with its CALLS and HANDLES; 3 calls return as CALLS kubernetes CONFIGURES 7,962 -> 7,609: all 353 are "nconf" inside encryptionconfig / authorizationconfig / authenticationconfig, and all 353 return as CALLS. 8 bogus Routes gone -- os.ReadFile of the serviceaccount namespace file, t.Run("/TwoWay"), "/tmp/test" -- with 26 CALLS, 2 HANDLES and 21 TESTS edges that pointed at them. 374 plain CALLS restored; 8 of them (validate.Monotonic and friends) had NO edge at all on main. GRPC_CALLS 60 -> 60. HTTP_CALLS 398 -> 407: nine calls main swallowed as route registrations now reach the existing arg_url heuristic like every other package. 88 of the 408 removed service-derived edges were read at the call site -- all of django and typescript, 82 of 402 in kubernetes: 88 false positives, 0 true positives lost. None of the three corpora uses a glued-name library, so the 47 entries are covered by the unit test only. Known limits: "_" is a separator, so optical_fiber.len still matches "fiber." exactly as requests_get matches "requests" by design; a lowercase id followed by a capital matches (kafkaProducer), which also admits a dioXide-style name; a user wrapper glued without a separator (mygetenv) is no longer classified; a glued-name library missing from the list is NONE until someone adds it.

the mcp.c and token-reduction parts are not taken). For C-family functions return_type was the text of the declaration's `type` node alone. In these grammars the `*`, `&` and `&&` live on the declarator and cv-qualifiers are sibling nodes, so const char *get_name(void) published char robj **lookupKeys(...) published robj Text &operator=(const Text &) published Text and no C or C++ function in any index had a pointer return type at all. The C/C++ resolver's return-type parser already strips a leading const/volatile and handles trailing `*`, `&`, `&&` -- branches that were unreachable for functions, so every `Foo *f()` was registered as returning Foo by value. c_declared_return_type() renders the declared type at both sites (functions and methods) for C, C++, CUDA, GLSL, HLSL, ISPC, Slang and Objective-C -- the list resolve_func_name_c_family uses: so `const char *`, `char **`, `Text &`, `Text &&`, `Text *&`, `volatile unsigned long *`; a pointer-level qualifier follows its star (`char *const *`); east-const `char const *` normalises to `const char *`. With no qualifier and no marker the old text is returned unchanged. It measures, then writes into one exact-size arena allocation; the declarator walk is a plain child chain, no recursion. def.return_types is untouched. Two deliberate differences from the upstream hunk. Upstream copied every type_qualifier node, which in these grammars includes constexpr, _Noreturn, mutable and __extension__ -- `constexpr int f()` would have become `constexpr int`. Only const, volatile, restrict, __restrict, __restrict__ and _Atomic are kept, and both cases are asserted unchanged. And the walk stops at the first declarator that is neither pointer nor reference, so `int (*f(void))(int)` stays `int` rather than becoming a wrong `int *`. RED, production reverted and the final tests kept: c_function_return_type_preserves_pointer_and_qualifier FAIL tests/test_extraction.c:1005: "char" != "const char *" cpp_method_return_type_preserves_pointer_and_qualifier FAIL tests/test_extraction.c:1072: "char" != "const char *" 351 passed, 2 failed c_function_return_type_plain_unchanged is the control: it passes before and after. GREEN: extraction 353, c_lsp 762, lang_contract 41, pipeline 281. Effect on real code -- Redis, production binaries, old against new. 39,132 nodes in both. 1,442 Function nodes change, in return_type only: void -> void * (270), char -> const char * (101), unsigned char -> unsigned char * (91), char -> char * (81), robj -> robj * (57), ... Functions with a `*` in return_type: 0 -> 1,440. With one worker the complete edge set apart from SEMANTICALLY_RELATED is byte-identical old against new across six runs (three each) -- CALLS, USAGE, WRITES, IMPORTS and the rest do not move. SEMANTICALLY_RELATED goes 350 -> 325 because that pass tokenises the return-type string into its type vector. One thing measured rather than assumed. With several workers, which `dict.h` Redis' src/dict.c imports (src/ or deps/hiredis/) depends on worker merge order. That is main's defect, not this change's: unmodified main picked src/dict.h in 2 of 10 runs and the hiredis header in 8; with one worker both binaries always pick src/dict.h. This change picked src/dict.h in 6 of 10. At ten runs a side that gap is not separable from chance (Fisher exact, two-sided p = 0.17), and a shifted rate would be unsurprising for a timing-dependent pick; it is recorded here rather than explained. The include-target fix is a separate change (#2227). Known limits, all pre-existing and out of scope: struct and class FIELDS have the same defect (`const char *data;` publishes char); C prototypes and declaration-only C++ methods are not extracted as definitions, so they are not reached; where a macro is misparsed as the type (`LUA_API const char *f()`), the base was already wrong and now reads `const LUA_API *`; the resolver's parser does not yet understand a pointer-level qualifier or a leading _Atomic/restrict and falls back to a named-type lookup for those, as it effectively did for every pointer return before.

One CreateDirectoryW wins; the others get ERROR_ALREADY_EXISTS. win_private_directory_tree_secure() treated that as a failure and recorded no validation detail, so every loser exited with a bare secure CLI coordination could not be created (endpoint) The function called right after the walk, win_runtime_directory_secure(), has always tolerated ERROR_ALREADY_EXISTS for the same directory, and the POSIX walk tolerates EEXIST at the same point; only the Windows walk in front of them did not. Seen four times on 2026-09-21 on unrelated PRs (#1768 three attempts in a row, #2140, #1999, #808). The racy lines date from July; the guard began exercising them on 2026-09-03, when each guard section was given its own empty CBM_RUNTIME_DIR, so the final component is now absent at storm time on every run. The walk now treats ERROR_ALREADY_EXISTS from its own CreateDirectoryW as "the directory I wanted exists". Nothing is trusted because of that: an ancestor still goes through win_directory_component_secure(), and the final component through win_runtime_directory_secure(), which refuses a non-directory or reparse point and enforces owner and DACL. Every refusal on this path now names its component and its rule. The walk reports the Windows error when it can neither create nor inspect a component, and win_runtime_directory_secure() says whether the path could not be created, cannot be inspected, exists but is not a directory, or is a reparse point. One helper owns the wide-to-UTF-8 conversion for these messages and the existing ancestor message now uses it too, so src/daemon/ipc.c stays at its memory-core baseline. Deterministic reproduction, no threads and no timing: a test seam fires in the walk between "component observed absent" and CreateDirectoryW, and the test plays the process that wins the creation. daemon_ipc_windows_private_directory_survives_lost_creation_race daemon_ipc_windows_private_directory_refuses_and_names_a_planted_file Verification. macOS arm64 (ASan+UBSan): build clean, daemon_ipc 53 passed (2 Windows-only skips), daemon_bootstrap 28 passed, lint-memory-core unchanged (ipc.c stays at 146 raw sites). The two new tests are Windows-only and have NOT been run locally: the Windows VM was down when this was written, so the RED run on the seam-only tree and the GREEN run with this fix are delegated to CI's windows-latest legs (test-windows shards, test-windows-guards) by an explicit maintainer decision. If the guard suite's cold storm still fails with this in place, the attribution above is wrong and this reverts.
