# Proof audit pass 1

Scope: [#23408](https://git.cafe/pingdotgg/t3code/issues/23408), branch `fix/issue-23408`, base [3b95e7831b](https://git.cafe/pingdotgg/t3code/commit/3b95e7831b), head [5db44425a7](https://git.cafe/pingdotgg/t3code/commit/5db44425a7606f2b6de3724acfefc9cbbbaddd25). Read-only review of the full two-file diff and relevant startup/test paths. No repository edits, captures, browsers, servers, forge writes, or new regexes.

## Render fixture matrix

Empty (0 fixtures). No changed render paths. The only runtime change prepends `--use-system-ca` to the primary desktop backend's Electron-as-Node argument vector. No JSX, CSS, renderer states, mobile views, or shared client behavior changed. Under the lead's stated procedure, nonvisual test/runtime proof applies; screenshots would not establish certificate trust or startup correctness.

## Nonvisual proof matrix

| Path / fixture | Required observation | Available evidence | Assessment / remaining proof |
| --- | --- | --- | --- |
| Primary packaged desktop configuration | Flag is a runtime argument before preload and backend entry; packaged compile-cache preload remains intact | Existing stable-bootstrap test now expects `--use-system-ca`, `--require`, compile-cache path, backend entry in order. Dedicated new test asserts flag precedes entry. Harness defaults to packaged darwin configuration. | Configuration coverage present. Mock platform is not a macOS runtime. |
| Regression red then green | New behavioral configuration test fails without the fix, passes with it | Test-only commit [aff87ef38b](https://git.cafe/pingdotgg/t3code/commit/aff87ef38bce97e58dfe354948fc0cd4d7c74c5e) precedes fix; source at that commit lacks flag. Lead reports red at that commit and 18 tests green after fix. | Commit structure and failing condition inspected; execution outcomes are lead-reported, not independently rerun or backed by a supplied test-output transcript in this audit. Preserve exact red assertion and 18-green command/output as PR evidence. |
| Production launch integration | Actual packaged backend starts successfully using generated arguments, preload, server archive, bootstrap FD, and readiness handshake | Manager source passes configured executable and args to ChildProcess.make. Tests exercise packaged paths including Windows server.asar. | Static wiring and configuration tests support integration, but supplied runtime transcript runs a standalone HTTPS script, not production backend startup. Obtain a short packaged-startup/readiness transcript with Electron version, argument order, no unknown-option/preload error, and isolated T3 home; redact bootstrap secrets. No server was launched in this audit. |
| Real TLS behavior, Linux | Version-matched Electron accepts flag; a chain rejected before reaches HTTP after | `/tmp/issue23408-runtime-probe.txt`: Electron 44.9.3 / Node 24.22.0 / Linux; api.github.com changes from UNABLE_TO_VERIFY_LEAF_SIGNATURE to HTTP 403. Probe uses node:https. `extraCA:false`; no NODE_USE_SYSTEM_CA field is emitted. Electron dependency is pinned to 44.9.3. | Supports runtime flag compatibility and TLS handshake improvement on this Linux host. HTTP 403 establishes reaching HTTP, not application authorization success or a relay connection. Transcript command lines omit explicit ELECTRON_RUN_AS_NODE setup; include the environment invocation in reproducible evidence. |
| Relay endpoint, Linux | Reproduce relay certificate failure before fix and remove it after | relay.t3.codes returns HTTP 302 before and after; other sampled endpoints keep their prior HTTP statuses. | No Linux reproduction of reported relay failure. This is unchanged reachability evidence only, not relay repair or full relay/WebSocket authentication proof. |
| Reporter macOS / Electron 44.9.3 | Same affected host/trust store fails before and succeeds after; actual desktop relay flow completes | Reporter scenario supplied by lead; no macOS execution in available transcript. | OPEN platform and symptom gap. Require affected macOS before/after runtime or reporter confirmation for a verified-fix claim. Linux results cannot establish macOS keychain behavior or desktop relay recovery. Say "enables system CA trust; macOS reporter validation pending" until then. |
| Windows native primary | Flag supported and packaged startup still succeeds with Windows trust store | Flag added unconditionally; existing packaged Windows configuration fixture covers archive entry but no Windows runtime execution supplied. | Runtime startup/trust-store validation absent. Record platform gap; do not claim Windows verified. |
| Development primary | Flag precedes entry without packaged-only preload | Unconditional flag is outside isPackaged preload conditional. | Static coverage only; no dedicated unpackaged fixture or runtime transcript supplied. Lower-priority startup smoke gap. |
| Provider / terminal environment | Fix adds no system-CA environment variable to child processes | New test asserts config.env.NODE_USE_SYSTEM_CA is undefined; implementation adds only argv flag. | Proves no new env patch. Because environment extension remains enabled, it does not prove an ambient user-provided variable is stripped, nor should evidence claim all provider trust behavior is verified. |
| WSL / CLI-hosted server / web / mobile | No new flag propagation or visible surface change | Only resolvePrimaryStartConfig changes; resolveWsl and other launch paths untouched. | Outside direct change. Desktop-hosted remote clients can benefit indirectly from corrected backend TLS. No separate visual fixtures or provider matrix needed. |

## Verdict

No scoped source-level proof blocker beyond the evidence limitations above. The empty visual matrix is justified. Red/green configuration evidence plus the Linux runtime transcript supports a narrowly worded candidate fix, not a verified resolution of the reporter's macOS relay failure. Production packaged startup is not demonstrated by the supplied HTTPS-only transcript. Preserve that distinction in the PR and obtain packaged startup plus macOS reporter validation before claiming those paths verified.

No checks were rerun: this pass audited source, commit ancestry, and existing runtime proof only. Working tree was clean on inspection.

## Friction

FRICTION platform-gap | Linux probe cannot reproduce the reporter's macOS relay failure; relay is 302 on both sides | Obtain a version-matched affected-macOS before/after transcript or reporter confirmation; keep current claims platform-scoped.

FRICTION proof-gap | Standalone HTTPS probe does not exercise packaged desktop production startup | Retain a separate isolated packaged-backend launch/readiness transcript, including full runtime invocation and redacted bootstrap handling.

FRICTION evidence-provenance | Red failure and 18-green result were supplied as lead assertions; no exact test-output artifact was supplied | Attach the focused test commands and outputs alongside the test-only and fix commits.

FRICTION audit-tooling | Initial broad temporary-file listing encountered unrelated permission-denied directories; one assumed startup filename was absent | Read named evidence directly and locate startup ownership with targeted rg before opening files.
