## Evidence Captured **11/11 affected rows**, **11/20 total matrix rows**. The nine optional controls/scope rows are accounted for below. Each link is an ordered, timestamped runtime recording, not a test result. **Beyond the PR title:** equal-version changed runners are also retained (A02). In the artificial SIGSTOP baseline (A11), attempted replacement encounters the still-held server-home lock; the head instead reports that the existing server was left running. This is disclosed as a controlled process-state fixture. Environment: fs-11 (`freestyle`), Linux x86_64, POSIX sh, Node v26.12.1; before [edc37c9](https://git.cafe/pingdotgg/t3code/commit/edc37c96c810d42761ab510c6a3e9d0a741547dc), after [b39fd40](https://git.cafe/pingdotgg/t3code/commit/b39fd402c62559744f892a2e164212a79e0a6ede). Each stable C=0.1.6 CLI was built in its own checkout with `vp run build:bundle`, with that checkout’s completed real web build. A labelled archive-packaging wrapper execs the real built `bin.mjs`; no helper shim or fake comparator. L=0.1.5 and H=0.1.7-nightly.20261102.4080 are unmodified, checksum-verified Linux release archives. A05 uses a head scratch source copy with only the package version changed. Fresh synthetic HOME/T3 homes per side and row; the local SSH stub executes the real transmitted launch script in a separate session, restores/asserts HOME after login startup, and uses loopback ephemeral ports. No real SSH, rendered UI, live user database, credentials or agent turn. The transcript archive includes both normalized sides, transmitted scripts, SSH argv/stdout/stderr, synthetic helper inputs and capture statuses. Diffs use literal `diff -u` after normalizing PID identities (preserving retention/replacement), timestamps, ports, temporary/check-out paths, owner UUIDs and Effect fiber IDs. Source SHAs and artifact/script hashes remain visible. Generated pairing tokens, links and QR presentations are redacted. ### What else changed - A01/A02: base has a replacement PID/runtime and an extra server startup/shutdown/pairing presentation; head retains PID/version/startedAt/port and has one server lifetime. A01’s real H archive has the same migration inventory as C in this fixture: this recording makes no migration-divergence claim. - A03/A06–A09: replacement remains observable on both sides. Direct head helper invocations and assertions add evidence steps for rejection and build metadata; those extra steps are harness coverage. - A04/A05/A10: base reports an absent keep-server command; head records production helper rejection, acceptance, or filesystem-read failure respectively. A05’s embedded version and build channel deliberately differ from the ordinary C build. - A11: base sends termination to stopped P, attempts a second server, encounters the held home lock, and reports new-server readiness failure; head retains stopped P/runtime and reports existing-server readiness failure with “server was left running.” Both restore P with SIGCONT before cleanup. - Build/source labels, bundled-file hashes, transmitted-launch hashes, and the added guard/helper evidence differ. Startup log scheduling (Listening versus standby/recovery ordering), cleanup-record order and instantaneous R/S process states vary. Fresh-run PID/port/time/path/owner/fiber values are normalized; generated pairing secrets are redacted. No broader “nothing else changed” claim is made. ### Recordings **A01 — Older C meets real newer H.** Base replaces H with C; head retains the same live H PID, version, startedAt and port.

These matrix-designated optional rows were not separately captured: | Row | Reason / coverage limit | | --- | --- | | C01 | Dev node-script runner: optional control outside this archive-guard recording. | | C02 | Unchanged-runner reconnect: optional control; captures deliberately force changed runners. | | C03 | External adoption: optional control; no foreign live server fixture. | | C04 | Cold starts occur during seeding, but dead/zombie-state variations were not separately recorded. | | C05 | Actual-port correction and failed adoption probe: optional controls, not independently injected. | | C06 | Gone/unready external remembered server: optional control, not seeded. | | C07 | Prerequisite/install/port exhaustion errors: no additional capture required by the matrix. | | C08 | Desktop pairing/cached tunnels/explicit disconnect: direct launcher harness intentionally bypasses these; no UI or shutdown claim. | | C09 | Already-shipped clients, real SSH, macOS, Windows caller, live agent turns, web/mobile consumers and tunnel shutdown: outside this Linux harness; no remote macOS host or T3 Connect available on the VM. | Cleanup: all tracked sandbox server PIDs are stopped/reaped; final process and checkout verification is attached separately. The base worktree is removed; the head worktree remains at the requested commit and clean. Nothing was committed, pushed, or written to the PR. Model/harness: GPT-6.1 Sol, Codex in T3 Code; Python lifecycle driver and local SSH stub, real generated shell and actual built CLI. ### Final verification and upload manifest [cleanup-audit.log](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/b3e91e24cd636925/cleanup-audit.log) [ghdrop-output.md](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/beb29574e3e13499/ghdrop-output.md) FRICTION: ```text infra | Each real web build took about 29 minutes on this VM; both completed | Prebuilt web assets or a documented server-readiness fixture would reduce capture setup time. runbook | vp’s Node shim tried to download Node under the fresh HOME | Resolve process.execPath before entering the sandbox. runbook | Initial local SSH harness let Effect terminate the local remote server process group | Start the stub’s remote shell in its own session to model real SSH. runbook | A pilot started before web assets existed and stayed at HTTP 503 | Wait for each checkout’s web build before cold launch. runbook | Scratch nightly staging initially omitted root config dependencies/schema, and vp run required absent workspace web metadata | Copy schema/config dependencies and use vp pack for the version-only scratch build. tool | Web fetch could not retrieve the supplied text artifact | curl retrieved the exact fixture matrix successfully. ``` PR [#29428](https://git.cafe/pingdotgg/t3code/pull/29428), head [b39fd40](https://git.cafe/pingdotgg/t3code/commit/b39fd402c62559744f892a2e164212a79e0a6ede); evidence complete, checks and reviews not assessed.
