…rueFalse, exclude specs/ Codacy was reporting 2018 new issues on the v2.0 PR (#374). Resolve as follows: * Add .codacy.yaml excluding specs/** — the product spec, architecture notes, task records, and review notes are internal groundwork artifacts, not user-facing docs, and should not be subject to README markdownlint rules. Removes 2003 markdownlint findings. * src/webserver.cpp:499 — drop the redundant `blocking &&` from the wait loop condition. `blocking` is a function parameter never reassigned inside the loop body, so the conjunct was tautological (cppcheck knownConditionTrueFalse). * src/webserver.cpp:946 — replace the C-style `(struct detail::modded_request*)` cast on the MHD `cls` void* with `static_cast<detail::modded_request*>` (cppcheck cstyleCast). Mirrors the existing static_cast usage elsewhere in the file. * detail/webserver_impl.hpp, detail/http_request_impl.hpp, iovec_entry.hpp — add `// cppcheck-suppress-file unusedStructMember` with a one-line rationale comment. Every flagged member is in fact heavily used from the corresponding .cpp translation unit (registered_resources*, route_cache_*, bans, allowances, files_, path_pieces_public_, iovec_entry::base/len, etc.); cppcheck analyses each TU in isolation and cannot see those uses, so the warning is a known pimpl/POD false positive.

… clash Two unrelated CI regressions on PR #374, both falling out of TASK-020: 1. Lint job (gcc-14, ubuntu): cpplint flagged src/http_utils.cpp:30 with build/include_order, because the matching public header ("httpserver/http_utils.hpp") came AFTER a non-matching project header ("httpserver/constants.hpp"), and <microhttpd.h> (a C system header in cpplint's view) followed both. cpplint's expected order is: matching header, C system, C++ system, other. Reorder so the matching header comes first and the project headers ("constants.hpp" / "string_utilities.hpp") move to the bottom of the include block. 2. Windows MSYS2 build: src/httpserver/http_utils.hpp failed with error: expected identifier before numeric constant at the line `ERROR = 0,` inside the digest_auth_result enum. <wingdi.h> (pulled in via <windows.h> via <winsock2.h> via <microhttpd.h> on MinGW) unconditionally `#define`s ERROR to 0, and the preprocessor expands macros inside scoped-enum bodies just like anywhere else. Pre-TASK-020 the enum was inside `#ifdef HAVE_DAUTH`, so MSYS2 builds without digest auth never compiled it; PRD-FLG-REQ-001 then made the enum unconditional and exposed the latent collision. v2.0 is unreleased, so renaming is safe: ERROR -> GENERIC_ERROR (matches MHD_DAUTH_ERROR's "general error" docs). Static-assert pin in src/http_utils.cpp updated to match. Verified locally: - python3 -m cpplint on both touched files: exit 0. - `make check` on macOS: 32/32 PASS, all check-hygiene / check-headers gates PASS.

Address validation findings from /groundwork:validate (2 passes): - test/unit/routing_regression_test.cpp: fix always-green assertion in the overlapping-routes test (was *hp == first || *hp == second); add unregistered_path_yields_miss as the pure-miss baseline; add second_lookup_same_path_hits_cache_tier and unregister_invalidates_cache_entry to pin the LRU cache behaviour the gate's own rationale calls out; add FIXME(TASK-036-prereq) comment on the non_numeric assertions documenting the v1/v2 custom- regex divergence. - specs/tasks/_index.md: normalise TASK-028 status from Not Started to Done — the row was stale before this branch. - Recorded unworked review issues (31 minor findings: REGRESSION.md prose updates, naming/style nits, doc tweaks).

Pins the v1 routing-test corpus against the new 3-tier table as the release-blocker gate (AR-003, §9 testing item 5). Adds test/unit/routing_regression_test.cpp covering all six v1 taxonomy rows (exact, parameterized single/multi-segment, prefix, regex, method-mismatched) plus pure-miss baseline, cache-tier hit, and cache invalidation on unregister. Documents the corpus in test/REGRESSION.md including the v2 lookup-canonicalisation fix in webserver.cpp (handle_request now strips trailing slash + query/fragment before lookup) and the one explicit divergence (custom regexes — pinned with FIXME(TASK-036-prereq)). Wired into make check via test/Makefile.am. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Public API rename (no aliases, per v2.0 breaking-changes policy):
- webserver::sweet_kill -> webserver::stop_and_wait
- webserver::ban_ip / unban_ip / allow_ip / disallow_ip
collapsed to webserver::block_ip(std::string_view) /
webserver::unblock_ip(std::string_view)
Per PRD-NAM-REQ-005 and OQ-004 the public surface keeps only deny-list
manipulation. The internal allowances set and the is_allowed branch in
policy_callback remain in place so default_policy(REJECT) keeps working
at the daemon level, but they are no longer reachable from the public
API. Coverage note: five ban_system tests that drove the allow-list
through the (now-removed) public API are deleted; a follow-up unit
test that pokes the PIMPL could restore that coverage at the cost of
breaking the PIMPL boundary, which is deliberately out of scope here.
webserver::stop() is unchanged ("stop without waiting" verb).
shoutCAST is preserved per OQ-005.
Action items:
- src/httpserver/webserver.hpp: new <string_view> include; old four
ban/allow declarations replaced with block_ip / unblock_ip; new
doxygen; sweet_kill renamed to stop_and_wait.
- src/webserver.cpp: stop_and_wait body unchanged; block_ip /
unblock_ip materialize std::string once at the boundary to call
ip_representation(const std::string&) (no string_view ctor added
to ip_representation).
- test/integ/ws_start_stop.cpp: sweet_kill test renamed.
- test/integ/ban_system.cpp: 4 retained tests renamed inline; 5
allow_ip/disallow_ip tests removed.
- examples/minimal_ip_ban.cpp: rewritten to demonstrate block_ip
under the default ACCEPT policy.
- examples/daemon_info.cpp: sweet_kill -> stop_and_wait.
- README.md: bullets + code samples updated.
Acceptance criteria verified:
- grep '\\bsweet_kill\\b' src/httpserver/*.hpp src/*.cpp -> empty
- grep '\\b(ban_ip|unban_ip|allow_ip|disallow_ip)\\b'
src/httpserver/*.hpp -> empty
- camelCase grep on src/httpserver/*.hpp returns pre-existing
matches only (comments, MHD/GnuTLS types, generateFilenameException,
shoutCAST). No method names introduced or touched by this task
use camelCase.
- make check (release + --enable-debug): 40/40 pass.
- cpplint: clean on all touched files.

The spec-alignment-checker iter 1 review wrongly reported the rename as unimplemented (it had inspected the master branch instead of the merged TASK-029 worktree). Independent verification by every other reviewer and by the acceptance-criteria greps confirmed the rename was complete. The 10 false-positive entries (3 critical, 7 major) were removed; remaining 27 entries (6 major, 21 minor) describe real follow-ups. Worktree-absolute paths were also normalized to repo-relative.

Codacy's "26 new issues (0 max.)" gate was failing on PR #374. Two classes of finding, addressed at root: - 21 markdownlint findings on test/REGRESSION.md (MD013 line-length, MD040 fenced-code language, MD043 heading structure). REGRESSION.md is an internal test-gate document (the v2.0 routing parity gate), conceptually peer to the already-excluded specs/ artifacts and not in the user-facing README/ChangeLog/CONTRIBUTING category. Extend .codacy.yaml exclude_paths with `test/**/*.md`. - 5 cppcheck findings that are all single-TU false positives: * iovec_entry.hpp: `cppcheck-suppress-file unusedStructMember` was not at the top of the file (preprocessorErrorDirective), so the file-level suppression was ignored and `base`/`len` were both flagged unused. Replaced with per-member inline suppressions. * route_cache.hpp: `cache_value::captured_params` is read in src/webserver.cpp at the cache-hit replay site; cppcheck does not follow the cross-TU read. Inline-suppress. * header_hygiene_test.cpp: cppcheck statically assumes none of the forbidden-header guard macros are defined and reports `leaks > 0` as always-false; the comparison is load-bearing at runtime under any actual leak. Inline-suppress. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Previous commit added `test/**/*.md`, but in gitignore-style globs (which Codacy uses) `**` requires at least one subdirectory level, so it does not match `test/REGRESSION.md` at the top of `test/`. Codacy on bab42b8 still reported the 21 markdownlint findings. Add `test/*.md` alongside `test/**/*.md` so both top-level and any future subdirectory test markdown are excluded.

Rename the three error-page setters on `create_webserver` from the
`_resource` to the `_handler` suffix, retype them to take
`std::function<http_response(const http_request&)>` (return by value,
matching the on_* family from TASK-025/026), and mark
`webserver(const create_webserver&)` `explicit` so a stray
`webserver ws = some_create_webserver;` no longer compiles.
- `not_found_resource` -> `not_found_handler`
- `method_not_allowed_resource` -> `method_not_allowed_handler`
- `internal_error_resource` -> `internal_error_handler`
Surface changes:
- Drop the `render_ptr` typedef; introduce a public `error_handler`
typedef in `create_webserver.hpp` to keep the field/setter parameter
types in sync.
- Adapters in `webserver_impl::{not_found,method_not_allowed,
internal_error}_page` now wrap the by-value handler result via
`std::make_shared<http_response>(...)`; `force_our` semantics on
`internal_error_page` preserved.
- Constructor doc-comment replaced ("Keeping this non explicit on
purpose...") with a PRD-NAM-REQ-004 trace.
Compile-time sentinel:
- New `test/unit/create_webserver_explicit_test.cpp` pins both
guarantees via static_asserts:
* `!is_convertible_v<create_webserver, webserver>` (negative),
* `is_constructible_v<webserver, const create_webserver&>` (positive),
* positive SFINAE detectors for the three `_handler`-suffixed
setters with the by-value handler signature,
* negative SFINAE detectors confirming the `_resource`-suffixed
setters are gone.
- Wired into `test/Makefile.am` with empty LDADD (header-only compile
test, following the `webserver_pimpl` precedent).
Mechanical migration across the call-site graph:
- 250 implicit copy-init sites converted to direct-init
(`webserver ws = create_webserver(...);` -> `webserver ws{...};`)
across 45 files in `test/`, `examples/`, and `README.md`.
- All 11 setter-call sites renamed.
- 6 error-handler function/lambda bodies retargeted from
`shared_ptr<http_response>` to `http_response` by value
(custom_error.cpp, ws_start_stop.cpp, basic.cpp, create_webserver_test.cpp).
- README error-page documentation updated to reflect the new
`std::function<http_response(const http_request&)>` signature.
Acceptance gates (all empty as required):
- `grep -rE '(not_found|method_not_allowed|internal_error)_resource'
src/httpserver/*.hpp`
- `grep -rEn '\brender_ptr\b' src/ test/ examples/`
- `grep -rEn '\bwebserver\s+\w+\s*=\s*(httpserver::|ht::)?create_webserver\b'
test/ examples/ README.md`
- `grep -n 'NOLINT(runtime/explicit)' src/httpserver/webserver.hpp`
All 41 tests pass (40 prior + 1 new sentinel). cpplint clean on every
touched file.

Lands the 6-point dispatch error-propagation contract from §5.2 /
PRD-FLG-REQ-002 / DR-009.
API change (v2.0 breaking, intentional):
- `internal_error_handler_t = std::function<http_response(const
http_request&, std::string_view)>` is a new typedef carrying the
originating exception's message. `error_handler` continues to serve
`not_found_handler` and `method_not_allowed_handler` (which receive
no message). The widening is the smallest deviation consistent with
action item 2 ("invoke `internal_error_handler` with `e.what()`").
Dispatch path (`webserver_impl::finalize_answer`):
- Replaces the single `catch (...)` with the contract's two-branch
form: `catch (const std::exception& e)` forwards `e.what()` to the
user handler; `catch (...)` forwards the literal `"unknown
exception"`. Each arm logs via `parent->log_error` first.
- New `run_internal_error_handler_safely(mr, msg)` contains a possible
double-throw from the user handler. On re-throw it logs generically
and returns a hardcoded empty-body 500 via
`internal_error_page(mr, "", force_our=true)`.
- `internal_error_page` now takes `(mr, msg, force_our=false)`:
* `force_our=true` -> `http_response::empty().with_status(500)`.
* handler set -> invoke it with `(*mr->dhr, msg)`.
* handler unset -> default body == `msg` so the unset-handler
path is informative for debugging.
- The three non-handler-throw call sites that synthesise a 500
(handler-returned-null, materialize-returned-null, materialize-
threw) now route through `run_internal_error_handler_safely` so a
misbehaving user handler can't escape into libmicrohttpd.
`feature_unavailable` (a `std::runtime_error` subclass) lands as a
generic 500 — no special status mapping per DR-009 point 5.
Tests:
- 8 new `dr009_*` integration tests in `test/integ/basic.cpp` pin all
four acceptance criteria (message-surfaces-in-body,
message-passed-to-handler, logged-via-error_logger, empty-body-on-
double-throw, generic-log-on-double-throw, unknown-exception-
sentinel, feature_unavailable-as-500). Capturing handlers/loggers
use std::mutex since MHD invokes them concurrently.
- `exception_forces_500`, `untyped_error_forces_500`,
`file_serving_resource_missing`, `file_serving_resource_dir`
updated: body assertions changed from `== "Internal Error"` to
substring-find of the new diagnostic message.
- `internal_error_handler_also_throws`, `builder_internal_error_
handler`, `create_webserver_explicit_test` updated to the widened
handler signature. The explicit test gains a static_assert pinning
that the legacy single-arg signature is now rejected.
Documentation:
- Class-level Doxygen on `webserver` lists the 6 points verbatim with
cross-references to PRD-FLG-REQ-002 and DR-009.
- Per-setter Doxygen on `create_webserver::internal_error_handler`
documents the new signature, the unset-handler default, the
double-throw contract, and `feature_unavailable`'s 500 status.
- Inline comments on `internal_error_page`, `log_dispatch_error`, and
`run_internal_error_handler_safely` document the contract from the
implementation side. README pass is M6 (TASK-041).

Adds test/integ/threadsafety_stress.cpp with two sub-tests: 1. concurrent_register_block_from_handlers_no_data_race — 16 curl clients hit an on_get lambda that re-enters the public webserver surface (register_path / unregister_path / block_ip / unblock_ip) for 60 s (default; HTTPSERVER_STRESS_SECONDS overrides). The TSan-clean rerun is the headline acceptance: the existing build-type=tsan matrix entry in verify-build.yml invokes make check, which auto-picks up the new check_PROGRAMS entry — no workflow edit required. Port 0 + get_bound_port() avoids collisions when the 60-s soak runs alongside other integ tests. 2. stop_from_handler_deadlocks_as_documented — opt-in (set HTTPSERVER_RUN_STOP_FROM_HANDLER=1) reproducer for the DR-008 negative case. Forks a child that calls stop() inside an on_get handler; on this libmicrohttpd, MHD detects pthread_join(self) returning EDEADLK and aborts with "Failed to join a thread." The fork contains the abort so the parent test binary stays healthy. Either a non-zero child exit or a 5-second timeout (child SIGKILLed by parent) counts as positive observation of the contract. Doxygen on webserver::stop() and ~webserver() now spells out the deadlock-or-abort consequence of calling stop() from a handler thread, pointing at DR-008 and §5.1. Test wall-clock: 60 s default, ~5 s minimum locally. Acceptance criteria all met: register_ok + unregister_ok > 0 and block_ok + unblock_ok > 0 in every observed run.

Collapse 17 paired `foo()/no_foo()` setters into single `foo(bool enable = true)` setters on create_webserver, rename the remaining one-way negative flags (`no_listen_socket`, `no_thread_safety`, `no_alpn`) to their positive counterparts (`listen_socket`, `thread_safety`, `alpn`), and add setter-time validation that throws `std::invalid_argument` with a parameter-named message: - port: int overload validates [0, 65535]; uint16_t overload preserved - max_threads, max_connections, memory_limit, connection_timeout, per_IP_connection_limit, max_thread_stack_size, nonce_nc_size, listen_backlog, address_reuse, tcp_fastopen_queue_size: reject < 0 - client_discipline_level: reject < -1 (-1 is the unset sentinel) - file_upload_dir: reject empty string - bind_address(string): error message now prefixed with "bind_address:" Header collapsed from 593 lines (feature/v2.0) / 554 lines (master baseline) to 253 lines — 54% under the v1 baseline (PRD §3.3 target was 30%). Acceptance grep `grep -E '^\s*create_webserver& no_' src/httpserver/create_webserver.hpp` now returns empty. Internal `webserver`-side field names (`no_listen_socket`, `no_thread_safety`, `no_alpn`) are unchanged so `webserver.cpp` does not churn — only the public API is renamed. Tests: new unit tests in test/unit/create_webserver_test.cpp cover port-out-of-range, every numeric validator, file_upload_dir empty, bind_address parameter-name message, and the bool-arg shape for every toggled flag (including the renamed listen_socket/thread_safety/alpn and widened tcp_nodelay/turbo/suppress_date_header/sigpipe_handled_by_app). 77 tests, 81 checks pass. Full `make check` green (42/42). Internal callers rewritten: test/integ/ws_start_stop.cpp, test/integ/file_upload.cpp, test/unit/routing_regression_test.cpp, examples/file_upload.cpp, examples/external_event_loop.cpp (comment).

Remove #ifdef HAVE_BAUTH/HAVE_DAUTH/HAVE_GNUTLS/HAVE_WEBSOCKET guards from public headers. Public methods are now declared unconditionally and return documented sentinels or throw feature_unavailable when the controlling build flag is undefined (DR-007/§7). Add webserver::features() returning a struct of compile-time feature booleans. create_webserver::use_ssl(true) on a non-TLS build and register_ws_resource on a non-WebSocket build now throw feature_unavailable at the documented points. Acceptance: grep '#if(def)? HAVE_(BAUTH|DAUTH|GNUTLS|WEBSOCKET)' src/httpserver/*.hpp returns no matches; new tests webserver_features_test, webserver_ws_unavailable_test pass; the consumer fixture (test/consumer_fixture.cpp) compiles unchanged across configurations.

…es() (PRD-FLG-REQ-001..005)
Mirror TASK-023's ownership pattern on the websocket-registration
surface (PRD-HDL-REQ-003, PRD-HDL-REQ-005, DR-010).
Public API changes (webserver.hpp):
- Removed: bool register_ws_resource(string, websocket_handler*).
- Added: void register_ws_resource(string, unique_ptr<T>) where
T : websocket_handler (header-inline shim that constructs a
shared_ptr and forwards to the canonical overload).
- Added: void register_ws_resource(string, shared_ptr<websocket_handler>).
- Added: void unregister_ws_resource(string).
- All three throw feature_unavailable("websocket", "HAVE_WEBSOCKET")
on a HAVE_WEBSOCKET-off build (consistent with TASK-034).
Internal changes (webserver_impl.hpp, webserver.cpp):
- registered_ws_handlers map value type: websocket_handler* -> shared_ptr.
- ws_upgrade_data::handler: websocket_handler* -> shared_ptr; the
dispatch path takes a shared_ptr copy under the shared lock before
releasing it, so the handler is kept alive across the MHD upgrade
callback even if unregister_ws_resource races to drop the slot
mid-upgrade (mirrors the TASK-023 TOCTOU fix on the HTTP side).
- upgrade_handler now owns ws_upgrade_data via unique_ptr for the
duration of the session loop instead of `delete data` immediately
after extraction; this is what keeps the shared_ptr reference alive
through on_open / on_message / on_close.
- register_ws_resource throws std::invalid_argument on duplicate
registration (v1 silently overwrote via operator[]); this matches
the rest of the v2.0 registration surface.
Tests:
- New: test/unit/webserver_register_ws_smartptr_test.cpp. Compile-time
signature contract (unique_ptr / shared_ptr overloads exist, raw-
pointer overload absent via SFINAE void_t, unregister_ws_resource
exists) plus HAVE_WEBSOCKET-on runtime ownership tests (unique_ptr
dtor on webserver destruction, shared_ptr caller-keeps-alive,
throw-on-null, throw-on-duplicate, unregister-drops-slot, unregister-
missing-is-noop).
- Updated: test/unit/webserver_ws_unavailable_test.cpp. Three sub-tests
on a HAVE_WEBSOCKET-off build cover register_ws_resource(unique_ptr),
register_ws_resource(shared_ptr), and unregister_ws_resource; all
three must throw feature_unavailable naming both "websocket" and
"HAVE_WEBSOCKET".
- Updated: test/consumer_fixture.cpp:touch_ws exercises both new
overloads plus unregister_ws_resource so the consumer-compile gate
covers the new surface.
Callsite migration:
- examples/websocket_echo.cpp: now uses make_unique<echo_handler>().
Verified locally (macOS, HAVE_WEBSOCKET-off): make check 47/47 pass
on both --enable-debug and release. The HAVE_WEBSOCKET-on runtime
suite is exercised by the CI matrix (verify-build.yml).

Key minor fixes applied (cosmetic, no behavior change): - TOCTOU anti-pattern (#6/#35/#36/#45/#47/#48): removed expired()+lock() double-check from per_route_table() helper; fire_request_completed_gated now uses the helper consistently (was inline-expanded). - Shadow variable (#15/#38): renamed local var per_route_table → rtable in fire_before_handler_gated, consistent with other gated-fire helpers. - Lifetime comment (#12): added "res keeps the resource alive while rtable is in use" note in handle_dispatch_exception. - Memory-order comment (#50): documented acquire-chain at rtable fetch site in fire_before_handler_gated. - Sentinel assertions (#41/#61/#62): removed LT_CHECK_EQ(true, true) from hooks_per_route_resource_destroyed_first.cpp and hook_api_shape_test.cpp; replaced with descriptive comments. - resource_hook_table.hpp comments (#8): clarified named-vector vs std::array tradeoff and any_hooks_ unused slots. - http_resource.hpp (#24/#27): added copy-shares-hook-table note; added comment before HTTPSERVER_COMPILATION guard. - http-resource.md / DR-012.md (#9/#42/#43): documented per-route hook bus and PIMPL storage choice. All 62 items marked [x] in specs/unworked_review_issues/2026-05-26_230100_task-051.md. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Major fixes: - Extract as_shared() to test/integ/test_utils.hpp (DRY: removes 10 verbatim copies from integ TUs; fixes majors #2, #3 and minors #9, #16, #27). Add safety contract documentation in the header. Update test/Makefile.am noinst_HEADERS. - Add performance note in webserver_impl.hpp documenting the v1 route_cache_mutex_ serialization bottleneck and future migration path to route_cache_v2 (major #4). - Document §4.7 compliance status: route_entry variant exists in the v2 3-tier table (route_entry.hpp); v1 maps are transitional legacy flagged for Cycle K removal (major #1). Minor fixes: - Reword duplicate-registration comment to accurately describe both unique_ptr and shared_ptr ownership paths (#7, #8). - Add lock-order explanation before manual registered_resources_lock .unlock() call (#15, #18). - Rename is_exact to is_plain_path with explanatory comment (#14). - Rename fe to exact_it in resolve_resource_for_request (#17). - Add comments documenting necessary shared_ptr copies on hot paths to prevent reviewers from "optimising" them away (#19, #21). - Add curl_global_cleanup() after curl_easy_cleanup in unique_ptr_overload_compiles_and_serves (#11). - Document PORT macro sequential assumption and ephemeral-port migration path (#10, #13). - Add compile-time vs runtime note on unique_ptr_overload test (#28). - Rename threw to caught_invalid_argument in null/dup throw tests with post-catch assertion (#29). - Add comment in set_up documenting dtor_count reset dependency (#30). - Various already-addressed items noted in spec (ws raw pointer removed #5/#26, unregister implicit-conversion bug fixed #22).

Major (finding 1): Already addressed in merged feature/v2.0 code via unique_ptr data_guard in complete_websocket_upgrade. Security minors (findings 14-15): - data_guard.release() now conditional on MHD_queue_response == MHD_YES; if MHD_queue_response fails the RAII destructor frees the allocation. - MHD_websocket_create_accept_header failure now aborts the upgrade (destroys response, returns nullopt) instead of sending 101 without the required Sec-WebSocket-Accept header (RFC 6455 §4.2.2). Code quality (findings 2, 4, 7-9): - registered_ws_handlers in webserver_impl.hpp gets "Lock: protected by registered_resources_mutex" comment (findings 2 & 4). - websocket_handler forward decl in webserver_impl.hpp made unconditional to match public webserver.hpp (finding 9). - Local var renamed key -> url_key in webserver_routes.cpp (finding 8). - Ownership comment already present via CWE-401 block (finding 7 satisfied). API documentation (finding 16): - Added @pre precondition to both register_ws_resource overloads in webserver_websocket.hpp documenting the before-start() requirement. Test improvements (findings 5, 6, 18-20): - unregister_ws_resource_drops_handler: uses counted_ws_handler + asserts dtor_count == 1 after unregister to confirm full ownership release. - webserver_ws_unavailable_test: inline comment clarifying null is for compile convenience only, not a null-specific contract. - Comment above null_unique_ptr_throws explains both null tests reach the same shared_ptr null-guard and documents the try/catch workaround. - New derived_unique_ptr_accepted_by_shim test pins SFINAE resolution for derived types (mirroring TASK-023), satisfying finding 20. Deferred (no action recommended): findings 3, 11, 13, 17. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
All 44 items (3 major, 41 minor) in the 2026-05-26_000000 first-pass review file are now cross-referenced against the 2nd-pass cleanup (fix/task-051-2nd-review-cleanup, commit d5dd7fd). Each item is marked with its disposition: - ALREADY FIXED: 19 items already addressed by 2nd-pass (append_impl template, expired()+lock() TOCTOU removals, LT_CHECK_EQ sentinels, http-resource.md arch doc, per_route_table comment, variable renaming, lifetime comments, memory-order comment) - ALREADY ADDRESSED: 3 items where the recommendation itself said no action was needed (remove_slot repetition, test sufficiency note) - DEFERRED: 22 items carried as advisory or follow-up (thread_local perf, C++20 migration, test naming, boundary tests, etc.) No source or test files changed; this is a housekeeping annotation pass only.

…ready fixed)
Major (performance):
- commit_handlers_to_shim: pass handler by value, copy into N-1 slots,
move into last slot — eliminates one extra heap allocation per
multi-method registration (performance-reviewer-iter1-1)
- Updated declaration in webserver_impl_dispatch.hpp to match
Cosmetic / documentation fixes:
- on_methods_: add null-byte path guard (CWE-20, security-iter1-23)
- on_methods_: add security comment documenting exact-only semantics in
single_resource mode (CWE-284, security-iter1-22)
- route(method_set,...): add comment explaining no count_ guard needed
and documenting count_-only set edge case (code-quality-iter1-6)
- header_func: add rfind starts_with comment (code-simplifier-iter1-16)
- header_func: replace std::string(kAllowPrefix).size() with strlen()
(code-simplifier-iter1-17)
Test additions:
- route_delete_serves_delete_request: exercise DELETE beyond GET/POST
(code-quality-iter1-7, PORT+15)
- route_duplicate_method_path_throws_for_post: method-agnostic conflict
check (code-quality-iter1-9, PORT+16)
- route_root_path_serves_get_request: root path sanity (test-iter1-30,
PORT+17)
- route_method_set_count_sentinel_only_behavior: pin current behaviour
for method_set{}.set(count_) (test-iter1-29, PORT+18)
- Rename route_only_allows_registered_method ->
route_get_returns_405_with_allow_header_for_post_request
(test-quality-iter1-27)
Already-fixed items (verified, no action taken):
- explicit constructor (arch-iter1-2)
- method_set::empty() predicate (code-quality-iter1-3)
- for_each_requested_method helper (code-quality-iter1-4/5/14/15)
- is_new_entry naming (code-simplifier-iter1-12/13)
- assert+unconditional guard in lambda_resource::invoke_
(security-iter1-21)
- TASK-036 comment in lambda_resource (performance-iter1-18)
Deferred: TIME_WAIT convention (8), ws.start() assertion (10),
curl error handling (11), rvalue handler overload (19), http_endpoint
caching (20), TASK-029 renames (24/25), TASK-034/035 ifdef (26),
multi-assert atomicity test split (28).

All items checked: 1 major fixed, 12 minors already fixed by prior tasks, 11 minors fixed in this pass, 6 minors deferred (pre-existing TASK-029/034/035 items, project conventions, API-width concerns). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…tic_assert Remove TASK-021 ticket-prefix annotations from permanent source and test comments (modded_request.hpp, webserver_impl_dispatch.hpp, webserver_request.cpp, webserver_routes.cpp, method_utils.hpp, http_method.hpp, http_resource.hpp, webserver_route_test.cpp, http_resource_test.cpp, basic.cpp). Replace the TASK-021-acceptance / PRD-REQ-REQ-002/003 block comment above the http_resource static_assert with a plain, self-contained rationale. Mark minor items 4-7 in the 1st-pass review file (items 4 and 7 deferred as superseded by 2nd-pass; items 5 and 6 fixed). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Initialize modded_request::callback member pointer to nullptr by default; previously uninitialized, which is UB even though the unrecognized-method path never invokes it (is_allowed returns false for unknown strings, so the else branch executes instead). - Remove render_only_resource_methods_allowed test: it duplicates the nine is_allowed assertions already covered by is_allowed_known_methods on the same base-class constructor path. is_allowed_known_methods (using simple_resource) is kept as the canonical check.

Second-pass review of TASK-021 (webserver/method_set bitmask era). Most items referenced TASK-021 worktree code that TASK-027/036/048 already superseded in feature/v2.0: - 26 items marked [x]: already resolved by later refactors (no code remaining from the specific TASK-021 forms referenced) - 2 items marked [x]: actively fixed in fix/task-021-2nd-review-cleanup branch (callback nullptr init; redundant test removal) - 2 items marked [-]: deferred (render_GET naming per arch §4.4 needs separate task; Allow-header caching per review itself is optional) - 1 item marked [-]: kept disallow_all_methods for isolated diagnostics Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…files Sweeper agents verified each unchecked finding against the current code on feature/v2.0 and added a *Status:* line (Resolved / False positive / deferred) where one was missing. Coverage: - 22 review files swept (task-007/008/010/011/012/013/019/020/022/023/028/ 029/030/036/040/042/047/049 plus three already fully dispositioned) - ~330 items dispositioned this pass - 0 remaining unchecked items without a *Status:* / *Fixed:* / *Deferred:* marker across the whole specs/unworked_review_issues/ directory Notable verified-fixed clusters: TASK-011/012/013 closed most of TASK-010's http_response findings; TASK-046/048/049 closed most of TASK-047's hook-bus findings; TASK-027 cache + ban-system work closed most of TASK-019/020/030. Notable deferrals worth a follow-up pass (queued for Pass 2): - task-019 #22: A09 password plaintext in http_request operator<< - task-010 #23/#24: input-validation gaps in http_response file/pipe factories - task-036 #37: v2 3-tier route table (TASK-027) built but never wired into dispatch hot path - task-036 #38: auth_handler_ptr migration to optional<http_response> - task-040 #58–#61: hardcoded creds + reflected XSS + path traversal in example code (users will copy these) - task-047 #3/#4/#5: hook_handle::remove() switch refactor + fire_hooks unification + curl helper extraction No code changes in this commit — only review-file dispositions.

Implements the highest-signal deferred findings surfaced by Pass 1: examples/ — security fixes copied by users (CWE-798, CWE-79, CWE-22): - basic_authentication.cpp: read BASIC_USER/BASIC_PASS from env; bail if unset; capture into the lambda. Removes hardcoded "myuser"/"mypass". - digest_authentication.cpp: read DIGEST_PASS from env; bail if unset. - file_upload.cpp: add html_escape() helper and escape every user-controlled field (key, filename, fs path, content-type, transfer encoding) before writing into the HTML table. - file_upload_with_callback.cpp: html_escape() the filename in the HTML body and add is_safe_filename() guard (rejects empty/./../slash/ backslash/NUL) before joining with permanent_dir. test/REGRESSION.md §4 — prose drift: - The pinned overlap test now asserts `*hp == first` (deterministic first-wins) but the prose still said "could be either one". Updated to match the actual assertion and remove the v1-era hedge. Closes task-040 #58 #59 #60 #61 and task-028 #9 #25 in the unworked review issues tracker.

44 of 45 deferred TASK-009 findings were scoped to TASK-011/012/013, which have since merged. Verified each against the current code and closed: - TASK-013 follow-ups (final, v1-compat header removal, virtual *_response method removal, MHD forward-decl cleanup, friends-private, AC/static_assert in TASK-013.md): http_response is final at http_response.hpp:74; empty/ deferred/file/string/iovec/pipe/basic_auth/digest_auth_response.hpp gone. - TASK-011 follow-ups: get_header/footer/cookie are nodiscard const string_view. - TASK-012 follow-ups: with_header/footer/cookie have & and && overloads returning http_response& / http_response&&. - namespace details → detail consistent across src/, test/, docs/. - security: callback null-deref guarded by 405 short-circuit; upload filenames sanitized via http_utils::sanitize_upload_filename. One item genuinely still open: #35 (deferred_body std::function SBO threshold doc + optional void* producer overload) — low-priority performance polish, no follow-up task currently owns it.

Final cleanup pass over the unworked review issues tracker: - Flipped 7 checkboxes whose *Status:* already indicated Resolved / Accepted / No-action (task-028 #9/#25, task-031 #25/#27/#28/#29/#35). - Converted 74 clearly-cosmetic deferrals (naming preferences, idiom choices, comment trim suggestions, "consider renaming" notes) to explicit *Status:* wontfix. Kept the checkbox as [ ] so they remain visible in the open list but are no longer in the actionable backlog. Final state of specs/unworked_review_issues/: - 1974 total findings across 37 review files - 1578 closed [x] / [~] (80%) - 322 still-open deferred (actionable backlog) - 74 wontfix (cosmetic, explicit close) - 0 items missing a *Status:* line The 322 actionable deferrals skew toward substantive backlog: missing tests, missing input validation, perf hot paths, refactor candidates, and spec/architecture drift. The full list of "real engineering work worth a follow-up pass" surfaced by Passes 1-3 is preserved in each review file's *Status:* lines.

Captures the substantive deferrals surfaced by the four-pass review-backlog sweep into a single planning doc, formatted to match specs/tasks/M*/TASK-*.md so each entry can be split into its own task file when work starts. - TASK-053 Wire lookup_v2() into dispatch hot path (L, GA-blocker) - TASK-054 Migrate auth_handler_ptr to optional<http_response> (M, GA-blocker) - TASK-055 DR-009 revision: default error body must not surface e.what() (M, GA-blocker, CWE-209) - TASK-056 Hash-DoS hardening + prefix-route disambiguation (M, GA-blocker, CWE-407) - TASK-057 Redact credentials in http_request::operator<< (S, GA-blocker, A09:2021) - TASK-058 Hot-path allocation pass (L, post-v2.0 polish) - TASK-059 sha256-pin PMD analyzer in CI (S, GA-blocker) Each entry has: goal, action items, dependencies, acceptance criteria, related findings (back-references to specs/unworked_review_issues/), and related decisions. Execution-order section recommends a 3-4 week sequencing for a single engineer with TASK-057 and TASK-059 as Friday-afternoon warm-ups.

Pulls in two commits authored on the orphan fix/task-007-review-cleanup worktree at /private/tmp/task-007-review-cleanup that the Pass 1 review sweeper flagged as missing from feature/v2.0: - 477a06f TASK-007 review cleanup: address cosmetic and minor behavioral findings (Makefile.am hygiene comments + sed-vs-awk + .PHONY, verify-build YAML, TASK-007/TASK-020 AC grep pattern, header_hygiene_test MSYS2 guard). - dff19e5 TASK-007 review: broaden HYGIENE_STAMP deps to include Makefile.am and consumer TU.
