# Bundle E — runtime evidence

**Additional differences outside child exclusion are present; see “What else changed”.**

Both sides: fs-18, Linux x86_64 6.1.102, Node v26.12.1, OpenCode 1.18.18 / `anthropic/claude-haiku-5-5`, Python 3.12 + websocket-client 1.9.2. Before home `/tmp/lead-26983-r1/evidence-capture/20261029T150359-before-measured/home`, port 19684; after home `/tmp/lead-26983-r1/evidence-capture/20261029T151950-after-final/home`, port 19685. Each source checkout is pinned and clean; external Node load-hook observation is disclosed in the transcripts, with its exact SHA-256. Every restart has its spawn PID, actual server PID, source SHA, port, home, observer hash and UTC time above the corresponding capture. Independent fresh databases; `T3CODE_DEV_SEED=0`. No browser, rendering, viewport/theme, Diff0 or DiffT applies. Timed captures use the real UTC clock and real one-minute scheduler, with the same scripted waits and activity leases; no fake clock is claimed.


Counts are completed `branchPullRequest` service calls (L), with descendant git subprocess attempts (G), attributed through trace/parent ancestry beneath each `ThreadPullRequestServiceV2.synchronize`. A cache hit is still a lookup. F separates failed wrapper attempts from real git executions. These are scoped service counts, not whole-server/provider process totals.

The ordered driver steps, exact UTC timestamps and restart environment appear before the paired trace excerpts inside each recording. Each per-request row contains trace/span IDs, branch attribution, discovery/validation counts, subprocess arguments/status and raw original service span objects.

## R13 — no foreground activity

| Measured interval or event | Before [37fbefd](https://github.com/pingdotgg/t3code/commit/37fbefd147197fab9d88f9c120560c3f21b52cfc) | After [45c1162](https://github.com/pingdotgg/t3code/commit/45c1162b91872e5e7a7ddd7843b24364caca0f4d) |
|---|---|---|
| Seeded startup, root + child, policy false | 2 L / 40 G | 1 L / 20 G |
| Minute policy checks, no synchronize request | No synchronize request | No synchronize request |

## R13 — targeted child update while still headless

| Event | Before [37fbefd](https://github.com/pingdotgg/t3code/commit/37fbefd147197fab9d88f9c120560c3f21b52cfc) | After [45c1162](https://github.com/pingdotgg/t3code/commit/45c1162b91872e5e7a7ddd7843b24364caca0f4d) |
|---|---|---|
| RPC socket without activity report; child metadata | 1 L / 0 G | 1 L / 20 G |

Raw `EVIDENCE_POLICY` records show `shouldRunOpportunisticWork:false` in the headless interval. Opening the RPC socket alone did not report activity.


## What else changed

The first headless child event costs 0→20 G while remaining one lookup: after excluded startup it has not received the same sweep cache warming. Setup root unsettle changes 8→15 G. Startup falls 40→20 G. These measurements do not imply lower git work for every later targeted request.

Synthetic IDs, provider transcript wording, real UTC timestamps, process IDs and scratch paths differ naturally. Same normalized fixture data and public actions are compared. Earlier after pilots are excluded from acceptance and retained separately.

Complete non-equal request-count inventory for these recording windows (including setup and provider boundary requests). An absent side means no corresponding request in that phase window; it is not silently treated as zero. The JSON inventory retains exact timestamps and span IDs.

| Phase / request (thread, event, status, refresh, ordinal) | Before L/G | After L/G |
|---|---|---|
| E / `["A-parent", "thread.unsettled", null, true, 1]` | 1/8 | 1/15 |
| E / `["W1", "thread.metadata-updated", null, false, 1]` | 1/0 | 1/20 |
| E / `["all", "startup", null, false, 1]` | 2/40 | 1/20 |
