From c8ce25cddb9efc8e4c48d5b4c7b1d58724124475 Mon Sep 17 00:00:00 2001 From: Matt Jones <47545907+SoundMatt@users.noreply.github.com> Date: Mon, 27 Jul 2026 09:44:39 -0700 Subject: [PATCH] =?UTF-8?q?fix:=20backlog=20sweep=20=E2=80=94=20send=20pro?= =?UTF-8?q?tocol-flags=20form,=20TARA/tara=20collision,=20subscribe=20race?= =?UTF-8?q?,=20spec=20v1.11?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - send: implement the §11.2 protocol-flags form (--zone/--type/--payload) for RCP alongside the existing streaming JSON sink, dispatching to the same in-process mock registry. Adds hex_decode and cmd_type_from_string helpers. (Closes #28) - Rename the hand-authored TARA.md to TARA-ANALYSIS.md so it no longer case-collides with the auto-generated tara.md on case-insensitive filesystems (macOS/Windows), which silently dropped one file's content on checkout. Update AUDIT_PACK.md and ROADMAP.md references. (Closes #29) - mock::Controller::subscribe(): hold mu_ across the closed_ check and the subs_ append (matching close()'s critical section) to close a TOCTOU race where a subscribe() concurrent with close() could return success instead of ErrClosed. Add a concurrent regression test. (Closes #30) - capabilities_json(): emit protocol/protocol_int, matching version_json() and the spec §12.2 single-protocol-implementation convention. (Closes #31) - command_latency_test: drop the CI-env-var-gated threshold (an unreliable proxy for "noisy scheduler") in favour of a single generous threshold applied uniformly, fixing a spurious failure observed on a non-CI sandboxed run. (Closes #32) - Bump kRelaySpecVersion 1.10 -> 1.11 (no behavioural changes needed; cpp-RCP already shipped a CLI target ahead of the v1.11 waiver removal). (Closes #33) - README: expand the Headers table from 2 to all ~43 public headers, grouped by concern per spec §13.7.2. (Closes #34) kVersion/PROJECT_VERSION -> 1.2.0 (new spec-conformance capability: the send protocol-flags form). 41/41 ctest suites pass; relay conform --strict PASS at spec 1.11.
