Resolve the macOS half of the SDD-119 item 3 single-source-of-truth follow-up. The chanora_bridge cdylib macOS deployment-target floor ('10.15') was previously hard-coded at 7 sites across Podfile and chanora_bridge.podspec; this commit collapses them to a single Ruby constant declaration in a new SoT file.
Selected Option B (Ruby constant) over Option A (.xcconfig — rejected because the podspec prepare_command runs before any xcconfig is applied) and Option C (versioned text file — rejected as overkill given both consumers are already Ruby). Realizes SAD-087(a)'s 'single macOS build-configuration location' mandate.
Out of scope: the pbxproj 'MACOSX_DEPLOYMENT_TARGET = 10.15' lines (565/666/717) belong to the PBXProject default config and are independently overridden to '11.0' at the Runner PBXNativeTarget level; they are the Runner app's floor, not the bridge cdylib's floor. The iOS half (IPHONEOS_DEPLOYMENT_TARGET=13.0) remains an open follow-up.
Files: new apps/chanora_flutter/macos/macos_deployment_target.rb (MACOS_BRIDGE_DEPLOYMENT_TARGET = '10.15'.freeze); Podfile + chanora_bridge.podspec require_relative the constant and consume it at 7 sites; docs/architecture/sdd.md SDD-119 item 3 rewritten + Notes bullet updated + v0.9.17 changelog entry.
SDD-120 amendment v0.9.15 → v0.9.16 reflecting commit 3a7750a discovery.
The two post-processor tools (emit_baseline, compare_baseline) were originally
specified in SDD-120 §2 as residing in crates/chanora_audio/benches/, with
[[bin]] declarations in Cargo.toml. The implementation discovered that Cargo's
dependency resolver only routes [dev-dependencies] to [[test]], [[bench]], and
[[example]] targets — NOT to [[bin]] targets under src/bin/ or to ad-hoc paths.
Routing serde_json (required by both binaries) as a regular [dependencies] entry
to support [[bin]] placement would force it into the production cdylib build,
contradicting SDD-120 §10 release-artifact isolation: "no production telemetry
export" and "no benchmark surface in shipping artifacts." Confirmed by the user's
question about whether benchmark crates ship in the release artifact (they must
not).
The correct Cargo-idiomatic placement is examples/. Cargo auto-discovers files
under examples/ as example targets; they receive [dev-dependencies] routing; and
they are excluded from cargo build --release and from flutter build --release
artifacts by Cargo design.
Amendment scope (SDD-120 only):
- §1 item 4: [[bin]] → [[example]]; cargo run --bin → cargo run --example.
- §2: added item 5 with the rationale clause + Cargo dependency resolver
explanation.
- §5 item 1: path benches/ → examples/; invocation flag --bin → --example.
- §5 item 4: dev-dependencies routing clause updated.
- §6 step 6/8: --bin → --example.
- §7 step 5: --bin → --example.
- §10 item 1: release-artifact-isolation bullet extended to cite the
[dev-dependencies] Cargo design mechanism that enforces it.
- §11 verification matrix unchanged.
- "Allocated to" line + "Software units" list updated to reference examples/
paths.
No semantic change to SDD-120: same harness, same metrics, same workflows, same
out-of-scope deferrals. The implementation at 3a7750a already lives at the
corrected paths; this amendment brings the SDD text into agreement with the
code.
Add SysRS-303/304, SysDes-149/150/151, SRS-204/205/206/207,
SAD-081/082/083, SDD-094/095/096/097, DEC-029/030.
Captures the v1 lifecycle redesign:
- Drop manual Start-audio button; audio engine is bound to voice-channel
join/leave (ensure_running on first join, shutdown_if_idle on last
leave). Output stream opens regardless of mic-permission state so
listen-only is a first-class flow.
- TransmitMode enum (Ptt / Continuous / VoiceActivity-reserved).
Default Ptt on fresh install. Persisted per identity.
- PTT release tail: 200 ms default (0-500 ms configurable) before
transmit gate closes, avoiding clipped trailing syllables.
- Hard-mute toggle overrides transmit gate regardless of mode/PTT.
- Bridge surface: drop start_audio/stop_audio; add
voice_join(channel_id) / voice_leave() and BridgeEvent::VoiceState.
DEC-029 rejects Flutter global-hotkey packages (hotkey_manager,
super_hot_key) for PTT: they wrap RegisterHotKey/RegisterEventHotKey
which consume the key and don't fire key-up, wrong primitive for PTT.
Native Rust DesktopPttBackend (SDD-083/084/085) stays authoritative.
DEC-030 defers Voice Activity Detection to P1. RMS / WebRTC VAD /
Silero VAD trade-off review (binary-size, dependency-surface, CPU
profile) postponed; TransmitMode::VoiceActivity reserved on the enum
surface so a P1 increment is non-breaking.
Validator clean: 304/151/207/83/97 IDs, strict layered sourcing
preserved, no new warnings beyond the pre-existing 35 old-package-name
filenames.
A P0 traceability audit per the project's compliance workflow
found exactly one gap across the 162 P0 SRS items:
* SRS-200 (mouse side buttons as bindable inputs for desktop
Global PTT) had no dedicated SAD item. The earlier baseline
matrix folded SRS-200 under the narrative
`SRS-195..203 -> SAD-071..079` umbrella, which technically
covered the requirement at the table level but did not give
SRS-200 a one-to-one SAD source the validator's strict
discipline expects.
Per the project's gate-check workflow (Case C —
BLOCKED_MISSING_SAD) this commit closes the documentation chain
*before* claiming compliance for the already-merged mouse-side-
button code path:
* `docs/architecture/sad.md` v0.9.4 — new `SAD-080` sources
SRS-200, allocates `Audio (Windows / macOS / Linux), Bridge,
Flutter UI`, and records the cross-platform mouse-side-button
surface as a software-architecture item. The §27 coverage
matrix gains a dedicated SRS-200 -> SAD-080 row.
* `docs/architecture/sdd.md` v0.9.4 — new `SDD-093` sources
SAD-080. Specifies the `PttInputClass` enum surface
(`None` / `Keyboard` / `MouseSideButton`), the rebind
contract on the Windows + macOS backends, the Linux portal's
pass-through behaviour, and the Flutter
`PointerEvent.buttons` bitmask capture (back = `0x08`,
forward = `0x10`). The §11 coverage matrix gains the
SAD-080 -> SDD-093 row.
* `docs/governance/traceability-matrix.md` v0.9.4 — the
`(DEC-026 mouse buttons)` row moves from
`SAD-072..074 / SDD-082..086` to the dedicated
`SAD-080 / SDD-093`.
* `docs/governance/baseline-candidate-validation-report.md`
v0.9.4 — ID totals advance to 302 / 148 / 203 / 80 / 93;
direct-layer-rule and undefined-reference counts remain
zero.
* `docs/governance/repo-format-validation-report.md` v0.9.4 —
same ID totals update.
Audit summary
-------------
* 162 P0 SRS items audited.
* 1 SAD-coverage gap (SRS-200) — closed by this commit.
* 0 SDD-coverage gaps (every PTT SAD has explicit SDD coverage;
the inherited baseline `SAD-032/033` are covered through the
documented range row, not individually).
* All Priority: P0 software requirements now have a strict
SRS -> SAD -> SDD chain on file.

Implementation status
---------------------
The mouse-side-button code was implemented in v1.0.0-rc.4 and
v1.0.0-rc.5 under the (then-implicit) PTT umbrella; the code
already matches the new SDD-093's contract verbatim. This
commit ships **documentation only** — it adds the SAD/SDD/matrix
rows that retroactively justify the existing implementation
under the strict traceability discipline. No code edits, no test
edits.
* `cargo test --workspace`: 67/67 green (unchanged).
* `cargo deny check`: advisories ok, bans ok, licenses ok,
sources ok.
* `cargo about generate`: zero new warnings (no Cargo.lock
delta).
* `flutter analyze`: clean.
* `tools/validate_docs.py`: all SRS/SAD/SDD coverage and
direct-layer-rule checks pass.
Outstanding open items remain live verification per
`docs/release/release-readiness-go-nogo-record.md`
(RR-PTT-001..006/008) and the DEC-012 legal review; both are
non-engineering work.

README §"Desktop Push-to-Talk" added between Architecture Overview
and Repository Layout: capability levels, per-platform strategy,
privacy posture, missed-key-up watchdog.
Tooling:
* `tools/validate_docs.py` copied from the gen2 zip into the
repo tree (was previously available only inside the zip).
Reports zero undefined refs, zero direct-layer-rule violations,
English-only CJK check passes. The 35 "old package-style
filename" hits are pre-existing and identical to the gen2
baseline (they live in `path-migration-map.md` and config-ID
headers of governance docs and are intentional per the path
migration policy).
* `.gitignore` adds `/gen2/` so the externally-provided review
package does not enter the repo.
No code changes in this commit; B (the implementation split into
`transmit_active` / `capture_active`, `PttCapabilityLevel`
reporting, `PttSanitizer` diagnostics rule, and the UI capability
badge) follows in a separate commit.
Imports the v0.9.2 documentation baseline and the bootstrap files
required by docs/governance/repository-bootstrap-plan.md v0.1.0 §3,
minus the justfile (added in the next commit).
This commit establishes the git history for the project. All previous
work lived only as filesystem state with no version control.
