# Gooo process diagnosis and next context — 2026-10-09

Public workbench [PR 47](https://github.com/kimjooyoon/gooo-ecosystem-workbench/pull/47),
source `829a3411c9a3f107699c435011fa3ef9548e8302`, reads failed native runtimes with
Gooo rules and emits a context index for subsequent tools. The compiler used locally is clean release candidate
`9d8bdd97979d19342d28c6cd99e9bd3786808213`, version 0.6.19-dev, Go 1.27.2.

`dogfood.tar.gz` contains both fixed-order and own-model runs against the original
61,439-byte Windows failure JSON from compiler run 37883255912. Each captured
input equals the original bytes. Both report `deadline-during-start` and
`inspect-start-and-parent-budget`. The original Start 2,854,721,800ns and Wait
510,000ns still sum to Wall 2,855,231,800ns. Source/model/binary/input hashes are
unchanged before and after the calls.

The two authored selection cases came from this failure; their six fields pass.
Actual input has no correctness label and stays 0/0. This is a regression example,
not held-out generalization. Generation model calls are 0/1, saved replay calls
are 0. The same existing QAT model has 2,096 bytes of tensors and model SHA-256
`3c68205a660695103712e2115ce90accd298b406dced8ad5c9b84bab0a202`.

The context index is 2,645 bytes for the model run. It contains typed inputs,
Gooo advice, observation scope and five artifact references with exact sizes and
digests. Each reference was checked against disk. The full diagnostic alone is
2,407 bytes, so the index is not smaller than every report. It gives consumers a
stable route to select evidence without loading the entire captured CI result.
The standalone `next-context.json` is copied from the model directory; its relative
artifact paths resolve inside the archived `context-dogfood/model` directory.

Final focused race tests passed in 3.510 seconds, including eleven synthetic
process-state combinations in fixed and model modes, the context projection,
large integers and original evidence references. Vet and command-package build
passed. The complete native race suite passed before the final context addition;
the PR's CI has now also passed the complete final revision.

## CI and merge completion

PR run 37891121183 and push run 37891116434 both completed successfully on the
exact source, attempt 1. Original artifact 11598194368 is 11,676,363 bytes with
SHA-256 `e199601e64560915748cdd31794a237210e25703e4ddad715f95c4a72fccc77e`.
Its ZIP digest and compiler source were checked. The retained original API-change
outputs preserve 51/51 authored fields, actual 0/0 and zero-inference replay.
The CI's compiler is merged dev `e8ccf425`, version string 0.6.18-dev, Go 1.27.2;
local measurements above use release candidate `9d8bdd97` and keep that identity.

Normal expected-head squash merge produced main
`59bc4118a5c4b50843412ed793d61373b065183f`. Its tree equals the tested source and
its sole parent is `fd53420e`. `ci-completion.tar.gz` retains CI metadata, merge
checks and the selected original compiler/API files extracted from the artifact.
The full ZIP remains the identified GitHub artifact and is not duplicated here.

Single local whole-command observations (fixed ran first):

| Mode | Wall seconds | User seconds | System seconds | Maximum RSS bytes |
| --- | ---: | ---: | ---: | ---: |
| fixed | 1.66 | 0.40 | 0.27 | 87,179,264 |
| model | 0.68 | 0.31 | 0.21 | 87,900,160 |

These include compilation, selection, execution and replay. Cache/order and other
work affect them. They do not establish speedup, model-only memory or host CPU
utilization. Next actions are returned as data; automatic execution is future work.
