Garry Tanandcapy-ai[bot] 61e201ec08 v1.91.295.0 fix(pregate): deleting or renaming a test no longer fails lanes (#3534)
* fix(pregate): removed paths owe no lane instead of failing PREGATE_NO_LANE

A deleted file or a rename's old name that no remaining test selects now prints
'removed (no lane owed): <path> — <why>' in lanes: a deleted test runs its owning
suite or names the files that lost their last test; a modified file whose only
test was deleted still fails, and an unreadable deleted test fails closed.

Fixes: #3529

* fix(pregate): pre-landing review fixes for removed paths

A removal owes what an edit owes: manifests, lockfiles, config, fixtures,
goldens, workflows and files a config still names keep PREGATE_NO_LANE. A test
reading a fully deleted directory is selected again, a deleted Rust module
selects its crate's tests, a test renamed to a non-test path is accounted as
deleted, and the owning suite is the tests that directly exercise the same files.

* fix(pregate): a removed file remaining code still imports fails closed

Pass-2 red-team: namedBy matched only full repo paths, so a deleted module
imported by a relative, extensionless or dotted specifier from untested code
was waived. removedPath now refuses when the import graph shows a remaining
dependent. Stale headers updated to say other removals owe what an edit owes.

* fix(pregate): removals the graph cannot see stay fail-closed

Step 11 adversarial and outside-voice findings: the waiver trusted SOURCE_EXT,
so Go, Ruby, shell, Rust and bin removals, files loaded by name and files a
nested config names relative to itself passed with no test; a rename's old
name skipped every check. Now every removed path is refused while a remaining
file imports it (directory references included); only JS, TS, Python and Dart
code is waived, never a file loaded by name; namedBy also matches paths
relative to each ancestor directory; Go and Ruby tests are refused; a rename's
old name goes through the same checks unless it is a test renamed to a test.

* fix(pregate): basename mentions and Go/Ruby test renames fail closed

Fix-check 2 (cycle 4, rule 23 grant from GStack Minder): a deleted file a
tested loader reached by path.join(__dirname, 'lib', 'value.js') was waived,
and a Go helper test renamed into another directory got the test-rename
exemption. namedBy now greps the basename repo-wide (non-Markdown); the Go and
Ruby test refusal runs before the rename exemption.

* docs(pregate): align removed-path prose with the waiver rules

Ship docs audit (gsta137-docs-1): name the snapshot, baseline and .gstack/
trees the waiver excludes, add usercustomize.py to the loaded-by-name list,
and give the unreadable-deleted-test explain line.

gstack digest v1.91.295.0 — regenerate/re-copy after upgrading gstack

Behavioral rules from gstack (https://github.com/garrytan/gstack), compressed for agent hosts without a full skill install. The full skills add workflows, reviews, and evals on top of these rules.

Ethos

  • Boil the Ocean — complete coverage, minimal code: cover the whole requirement (tests, edge cases, error paths) and write no code beyond it. Shortcuts need an explicit, recorded decision.
  • Search Before Building — know what exists before deciding what to build. Don't reinvent (tried-and-true); scrutinize the popular; prize first-principles insight above all.
  • User Sovereignty — models recommend, the user decides. Cross-model agreement is signal, never permission. Ask before changing the user's stated direction.
  • Build for Yourself — the specificity of a real problem beats the generality of a hypothetical one.

The reuse ladder

Before writing new code, stop at the first rung that holds:

  1. A helper, util, or pattern already in this repo.
  2. The standard library.
  3. A native platform feature (CSS over JS, DB constraint over app code).
  4. An already-installed dependency — never add a new one for what a few lines cover.

Then build the complete version of what remains. Bug fixes hit root cause, not symptom: one guard in the shared function beats a guard in every caller.

Voice

Direct, concrete, builder-to-builder. Name the file, function, command, and user-visible impact. Short paragraphs; end with what to do. No filler, no corporate tone, no AI vocabulary.
