* enhance(#4406): the lazily-read remainder and the artifact templates
ADR-4139 Decision 3, Phase 6 of the #4139 Compact Content epic. Covers stream 1b
(gsd-core/workflows/<name>/{modes,steps,templates}/*.md) and stream 4
(gsd-core/templates/**) with a variant-swap mechanism, confirmed with the user:
two independent, complete files per covered path (canonical + .compact.md
sibling), with the gate picking which one gets Read at the call site. This is
a different shape from Phase 5's spine+detail partition, and is safe here
specifically because these files are already reached only by a runtime Read —
a missed Read already means zero overlay content today, with or without
workflow.compact_content, so selecting between two independently-complete
files introduces no new failure mode (documented in
gsd-core/references/compact-content-gate.md's new "Streams 1b and 4" section).
Disposition, after inspecting every candidate rather than trusting a byte-size
threshold (same rigor Phase 5 applied to review.md):
- Stream 1b: 1 of 78 files compacted (help/modes/full.md, a user-facing
reference doc emitted verbatim, not orchestrator instruction). The other 9
size-threshold candidates are dominated by fail-closed guards, exact CLI
invocations, or output-format contracts (AskUserQuestion blocks) — recorded
not-worth-compacting, same reasoning as Phase 5's review.md.
- Stream 4: a ground-truth reachability audit replaced the initial size-only
candidate list. Two files (summary.md, user-setup.md) got compact variants;
a third (spec.md) was drafted, then dropped after discovering its only two
call sites are eager @-includes, not a runtime Read — stream-1 material
hiding under gsd-core/templates/, not stream-4's actual mechanism. summary.md
itself has 3 eager call sites and only 1 genuine runtime-Read call site
(execute-plan.md); only that one was wired, so the compact variant's savings
apply to the sequential single-plan execution path only.
- Discovered while auditing reachability: 12 gsd-core/templates/** files with
zero references anywhere in workflow/agent/command prose, compiled source,
or tests — dead scaffolding predating this phase. Deleted in this same PR
per this repo's no-defer policy, after re-verifying against a computed
path.join(...) pattern (not just a plain-string search) that nearly caused
two genuinely load-bearing templates (user-profile.md, dev-preferences.md)
to be misclassified as dead.
New checker (tests/helpers/compact-content-variant.cjs): registration,
reachability, protected-content-preserved, size-smaller — replacing Phase
3/5's disjointness/completeness checks, which assume a partition rather than
two deliberately-overlapping documents. The reachability check's own
"unprefixed match" guard had a real bug (rejected the repo's own
`~/.claude/gsd-core/...` convention), caught by running it against the
already-wired help/modes/full.compact.md pair rather than only synthetic
fixtures — fixed to anchor on the nearest `gsd-core` path segment instead.
Template consumer parity (tests/compact-content-template-variant-parity.test.cjs):
proves each compact variant's `## File Template` fenced block — the actual
output-format contract a generated SUMMARY.md/USER-SETUP.md is parsed
against — is byte-identical to the canonical file, then runs the one real
deterministic consumer (gsd-core/bin/lib/coverage.cjs's classifyContent,
backing `gsd-tools uat classify-coverage`) against content built from that
shared contract.
Added a sibling benchmark script (scripts/benchmark-compact-content-variants.cjs)
rather than extending the existing spine/detail one — different data shape,
and the existing script's own contract deliberately isolates it from a
test-only helper's shape changing.
Emitted-drift acknowledgement: not needed. Every changed/added path in this
diff is hand-authored and present in the diff itself, so diffEmitted's
attribution loop resolves `via` to the path's own source before reaching the
ack-lookup branch (same reasoning Phase 5 verified for its own diff).

* enhance(#4406): address code-review findings on the variant-swap gate
- docs/CONFIGURATION.md and gsd-core/references/planning-config.md's
workflow.compact_content entries described only the spine+detail mechanism
(Phase 5) and were missing this phase's variant-swap mechanism and its
benchmark:compact-content-variants script entirely — required since this
PR's changeset is type Added (CLAUDE.md's "Missing Docs for Changesets"
rule). Both now describe both mechanisms and which call sites are wired.
- Added the missing RED^-1/no-op fixture for checkProtectedContentPreserved:
a canonical file with zero <!-- gsd:protected --> blocks must be a
no-op, not a violation — the only branch of that function the existing
fixtures didn't exercise.
- Collapsed findCompactFiles/findMarkdownFiles in
tests/helpers/compact-content-variant.cjs into one findFilesWithSuffix
helper — the two were identical recursive walks differing only in the
extension predicate (minor Duplicated-Code finding).

* fix(#4406): restore copilot-instructions.md, a false-positive dead-template classification
gsd-test caught this, not static analysis: 10 real failures in
tests/copilot-install.test.cjs, tests/installer-migration-install.integration.test.cjs,
and tests/repo-layout.test.cjs — all downstream of bin/install.js's Copilot install
path, which does
fs.readFileSync(path.join(targetDir, 'gsd-core', 'templates', 'copilot-instructions.md'))
after copying gsd-core/templates/** into the target project, then merges it into both
.github/copilot-instructions.md and (local installs) AGENTS.md. The reachability audit
that flagged this file as dead checked src/*.cts and gsd-core/bin/*.cjs but never the
repo-root bin/install.js — a separately maintained installer bundle outside the
src/-to-gsd-core/bin/lib/ compiled-output convention. The fs.existsSync guard around
that read degrades to a silent skip rather than a crash when the template is missing,
which is why this surfaced only once the real E2E install test ran, not from any
static check.
Re-verified the remaining 11 deleted filenames against bin/install.js specifically
(plain substring and quoted-filename search) before trusting that list — all 11 have
zero hits there, confirmed dead by the same standard this one file failed.
Regenerated the installer emitted-tree goldens (tests/fixtures/install-tree/*.json) to
reflect the restored file, and corrected the "Removed" changeset (jolly-lynx-sprint.md)
and the phase design doc from 12 to 11 deleted files.

* fix(#4406): resolve removed-but-needed lint findings on the dead-template deletion
CI's own full-test matrix (not gsd-test's matrix, which does not run this
check) caught 4 more false-positive dead-template classifications via
tests/removed-but-needed-lint.test.cjs / scripts/lint-removed-but-needed.cjs
— a literal, word-boundary basename check across .github/workflows/,
gsd-core/, and docs/ (excluding docs/adr/** and docs/research/**) for every
file a PR deletes. It has no semantic awareness, so a deleted template's
basename colliding with something else entirely still fires:
- claude-md.md: gsd-core/templates/README.md had a stale table row claiming
/gsd-profile reads this template to generate CLAUDE.md. Verified false (no
code reads it anywhere, same search that already covered bin/install.js) —
fixed the row to *(inline)*, matching every other command-generated
artifact in that table. File stays deleted.
- codebase/testing.md: collided with docs/guides/testing.md, an illustrative
example row in docs-update.md's sample output table (an unrelated real
generated-docs path). Swapped the example topic to "contributing" — the
row is illustrative, any topic works. File stays deleted.
- codebase/architecture.md, codebase/stack.md: collided with docs/reference/
planning-artifacts.md's directory listing of a user's own generated
.planning/codebase/architecture.md and stack.md output — the same
semantic mismatch already investigated and dismissed as unrelated earlier
in this phase's audit, now caught by a gate instead of judgment. That
listing repeats across 5 locale copies of the doc.
- continue-here.md: collided with the real .continue-here.md pause-work
artifact, referenced across 15+ locale and workflow files.
For the last two, the lint's own error message offers "restore the file or
update every consumer in the same commit." Rewording 15+ files across
languages I cannot verify translation quality for, to shave 2 already-tiny
templates that were merely presumed dead, is disproportionate to this PR's
actual scope — restored codebase/architecture.md, codebase/stack.md, and
continue-here.md instead, and corrected docs/ARCHITECTURE.md's Templates
section accordingly.
Final confirmed-dead set: claude-md.md, codebase/concerns.md,
codebase/conventions.md, codebase/integrations.md, codebase/structure.md,
codebase/testing.md, debug-subagent-prompt.md, discovery.md — 8 files, down
from the original 12. Verified locally: GSD_REMOVED_BUT_NEEDED_BASE=next
node scripts/lint-removed-but-needed.cjs now passes clean.

* fix(#4406): split codex-config.test.cjs to fix a genuine Windows CI timeout
Root cause of the `full test (windows-latest, 24, shard 2/3)` failure the
user asked to be actually fixed, not just re-run past: PR #4497 (landed
2026-09-07, one day before this PR's CI run) isolated
tests/codex-config.test.cjs into its own dedicated chunk because its
measured weight (17.87, ~45% of the post-cut Windows budget) made it unsafe
to share a chunk with any other file. That isolation was necessary but not
sufficient — even alone, with zero companion-file contention, the file's
real Windows execution time sits right at the 600s per-chunk ceiling. Two
independent CI runs on two unrelated PRs (this one and #4154) were both
killed within ~1.4s of the identical 600000ms mark — not random contention,
a deterministic near-miss the isolation fix couldn't address because it
never reduced the file's own cost, only removed the risk of a companion
file's cost stacking on top of it (which the PR #4497 comment explicitly
anticipated: "if a future profiling pass genuinely speeds up
codex-config.test.cjs itself, this isolation can be revisited").
The file itself explains why it's this heavy: 11,262 lines / 433 tests / 79
describe blocks, accumulated over dozens of bug-fix PRs (#2695, #2760,
#3245, #3285, #3346, #3426, #3427, #3562, #3566, #3582, #3808, and more),
several of which are explicitly documented as "folded" in from separate
files that were never actually split back out ("Verified non-duplicate
against both the pre-existing target and the other three folded sources").
Split into 4 files by top-level AST statement boundaries (never a naive
column-0 regex — an early attempt at that overcounted 79 apparent
"describe(" matches when only 21 are genuinely top-level; the rest are
nested inside a handful of large folded-in blocks, which a regex can't tell
apart from real top-level statements). Verified lossless twice: the split
script asserts byte-for-byte reconstruction of every source character, and
independently, total test()/describe() call counts match exactly between
the original file and the sum across all 4 new files (433/79 both sides).
Each new file carries the complete original shared header (imports/helpers)
for safety; per-file unused-import warnings from that duplication are
resolved via ESLint-precise alias renames (`{ foo: _foo }`, the standard
form for an intentionally-unused destructured binding — never a bare `{
_foo }`, which would destructure a different, nonexistent property).
No change needed to scripts/run-tests.cjs's ISOLATED_HEAVY_FILES or its
pinned test in tests/run-tests-harness.test.cjs: the file that keeps the
original name (tests/codex-config.test.cjs) is now only ~28% of the
original's size and safely isolated in its own chunk as before; the other
three new files re-enter normal weight-balanced packing, none individually
close to disproportionate. Confirmed no other file hardcodes the hardcoded
filename anywhere that would silently stop these tests from running (the
CI test-selection scripts determine scope algorithmically, not by literal
filename).
