# Precheck receipt — D1/D2, single granted launch (#300)

**Status: CLOSED.** This closes the precheck only. It is **not** an answer to #300's
submission-provenance question and **not** adapter acceptance. No rerun, resume, or battery is
authorized.

## Results — recorded narrowly

**D1 = YES, for this one print-mode submission.** `UserPromptSubmit` fired, evidenced by artifacts in
*its own attributed transcript* (new since the pre-launch inventory **and** carrying the nonce):
`hook_additional_context`/`hook_success` with `hookName=UserPromptSubmit`, plus `SessionStart`
artifacts that establish the hook configuration loaded for that spawn independently of D1 itself.
**This is not a universal hook guarantee** — it is one submission, on this host, in this
configuration.

**D2 = YES, for transcript persistence after termination.** An attributed transcript existed on disk
after the process was terminated. **`WINDOW=UNESTABLISHED`**, so **neither mid-turn termination nor
resumability was established** — the earlier phrasing "persisted through mid-turn termination"
overstated it and is withdrawn. Tool-call evidence is a *recording* time; it does not establish the
turn was live at termination. No resume was performed.

**Unexplained, and left unexplained:** the `hook-trace.log` slice for this window contained no entry
attributable to the spawn — only two lines from the live `perri` session. The trace did not roll (the
slice was read under the roll guard and returned clean). No causal conclusion is drawn.

## Evidence directory — full path

```
C:\Users\decid\AppData\Local\Temp\claude\C--Users-decid-Documents-projects-spt-claude-code\19d48c98-d787-4436-90c2-da3f52339ae1\scratchpad\precheck\out
```

That directory is the session scratchpad and is session-scoped, so it is **not** a durable locator on
its own. It is left **untouched**.

## Durable archive — recoverable bytes, not just hashes

```
C:\Users\decid\Documents\projects\spt-claude-code\.claude\reports\2026-09-12-precheck-d1-d2\archive
```

All **18** evidence files were copied there and **verified against the manifest below: 18/18 hash and
length match, 0 mismatches**, 885,793 bytes total. The scratchpad source and the original transcript
were left untouched.

The archive carries a `.gitignore` excluding its own contents: this repo mirrors publicly and the
archived transcript is raw session content that must not ride along. **The bytes are retained locally
and deliberately not committed or mirrored** — this receipt is what is committed.

`precheck.preexisting.txt` is **0 bytes**: **the scoped pre-launch inventory contained no records.**
That is a statement about the transcripts under this one slug and nothing more — it says nothing about
shared files outside that inventory. `precheck.spawn.json` / `.err` are empty — the child was terminated
before print mode emitted its JSON.

## Retained in place — nothing was deleted

| Artifact | Full path | SHA-256 |
|---|---|---|
| Original transcript (**not** removed) | `C:\Users\decid\.claude-spt\accounts\alt\projects\C--Users-decid-AppData-Local-Temp-claude-C--Users-decid-Documents-projects-spt-claude-code-61a5cd70-a460-42b8-9332-60f6bfe05a40-scratchpad-trust-probe31\3886ff4c-0d53-47c6-b780-d6519efdb741.jsonl` | `e1694adcb7efc21fc9709766469dbdbda1088af43e8a428b142c9fd7107bac36` |
| `WORK` (created empty by this attempt) | `C:\Users\decid\AppData\Local\Temp\claude\C--Users-decid-Documents-projects-spt-claude-code\61a5cd70-a460-42b8-9332-60f6bfe05a40\scratchpad\trust-probe31` | directory, 0 entries |

The evidence copy and the retained original hash **identically** (`e1694adc…`), so the copy is
byte-for-byte the file that was left in place.

## Bounds held

One launch; no retry, resume, interactive fallback, elevation, fleet mutation, or artifact deletion.
No trust or settings write. Ordinary runtime transcript/session bookkeeping in the shared credential
root occurred as ruled acceptable for this one check.
