### 2026-10-07 replacement Windows candidate (beta15)
### 2026-10-07 replacement Windows candidate (beta16)

The current replacement candidate is `d75bb952f725fb3f15d6c9b812c973b2ea5b49b0`, the merge commit for
[#656](https://github.com/scgopi/GraphCode/pull/656), with parents
`91707e3a3462c878e97dfed2446a09b30fa1426e` and
`5a460b70326d37f00beafd6c23ef535d567af0f7`. It replaces
`0.1.78-windows.beta15`, which is failed/superseded and immutable.

**The beta15 failure.** In the beta15 Dev Box run (step 7A), loop A was stopped,
loop B was opened, and then A was reopened. The visible pane kept B's session,
inside a stray selected "shell" tab that UIA did not expose. The cause was that
every `graphChanged` ran `refreshWorkspace`, which passively attached the
graph's first two loops to terminal slots in graph order.

**The fix (#656).** The refresh now re-observes only the open loop's own
detached pane, in the loop slot, after checking that the workspace project and
layout own it. The legacy graph-order attach remains only for `--smoke`. #656
merged with exact-head CI green and changes only the Windows Zig shell.

**Local validation.** Full local Windows-shell validation passed at the
candidate source with `VALIDATE_EXIT=0`:

- **55/55** sections;
- App **873/873**;
- scrubbed startup **5/5**;
- the real-daemon round trip;
- the live UIA gate.

**Tag and package.** The local annotated tag `0.1.78-windows.beta16` has tag
object `7a8ca3b5f5f9aed79c9f23f35e6a5844cdd3e27c` and peels exactly to the
source. It is local, unpushed and unpublished.

- The unsigned ZIP is **48,364,114 bytes**, SHA-256
`82ca44f64990867c85f1ad8a3b0d7793865883820a2e4f5efa94581c2c70630e`, with
**50 files**.
- The payload-manifest SHA-256 is
`1a9760ca8b4e824715c9d69dcc6300bd2ab5b2d18605052f4e0d578b10fd2cb4`.
- Repository and extracted setup verification each passed once.
- The binary reports `available`.

Executable SHA-256 values:

| Executable | SHA-256 |
| --- | --- |
| shell | `88a614db01f8973127cdeeea1b140a654e0524c59689400d5d7d05fc47b1ac88` |
| daemon | `30761427b73f9876819c42a712c409b57799c097fe2f814249c71fe1ca5fe877` |
| CLI | `5187457d32a8fe892c3d47155e605010156d4d2b3f9b62118dc9f61450972896` |
| zmx | `f7ff3aa347cad13fb1ad0121a62cb5db6e71d6abbd5a67cd772eae5864858ce5` |

The daemon and CLI are byte-identical to beta15. The packaged binaries passed
scrubbed startup **5/5**.

**Source custody.** The custody ZIP SHA-256 is
`f9aa87773027e76c49d4a3af70be45a72ed9fbaf2b17864b9178ba50d1d6ae04`. Create,
Verify and the file-only offline restore passed, with **43/43/43** LFS files,
exact detached HEAD/tag, zero remotes and clean status.

**Handoff.** The handoff `GraphCode-DevBox-Handoff-0.1.78-windows.beta16` has
`hashes.sha256` SHA-256
`78ea03fada20125138911a2221e34b5d719ebee3d1d6cac8139a62470f0777a6`; all
**8/8** entries verified.

- Approval A is unchanged: `AvailableInspectionOnly`, reclaim not authorized,
no dump.
- The prompt adds the A → B → A reopen check to step 7A.
