Compress without removing behavior or voice. Three targeted cuts:
1. scripts/resolvers/testing.ts coverage diagram example: 40 lines → 14
lines. Two-column ASCII layout instead of stacked sections.
Preserves all required regression-guard phrases (processPayment,
refundPayment, billing.test.ts, checkout.e2e.ts, COVERAGE, QUALITY,
GAPS, Code paths, User flows, ASCII coverage diagram).
2. scripts/resolvers/preamble/generate-completion-status.ts Plan Status
Footer: was 35 lines with embedded markdown table example, now 7
lines that describe the table inline. The footer fires only at
ExitPlanMode time — Claude can construct the placeholder table from
the inline description without copying a literal example.
3. Same file's Plan Mode Safe Operations + Skill Invocation During Plan
Mode sections compressed from ~25 lines combined to ~12. Preserves
all required test phrases (precedence over generic plan mode behavior,
Do not continue the workflow, cancel the skill or leave plan mode,
PLAN MODE EXCEPTION).
NOT touched:
- Voice directive (Garry's voice — protected per CLAUDE.md)
- Office-hours Phase 6 Handoff (Garry's voice + YC pitch)
- Test bootstrap, review army, plan completion (carefully tuned behavior)
Token savings (per skill, system-wide):
ship/SKILL.md 35474 → 34992 tokens (-482)
plan-ceo-review 29436 → 28940 (-496)
office-hours 26700 → 26204 (-496)
Still over the 25K ceiling. Bigger reduction requires restructure
(move large resolvers to externally-referenced docs, split /ship into
ship-quick + ship-full, or refactor the coverage audit + review army
into shorter prose). That's a follow-up — added to TODOS.
Tests: 420/420 pass on gen-skill-docs.test.ts + host-config.test.ts.
Goldens regenerated for claude/codex/factory ship.

Splits scripts/resolvers/preamble.ts (841 lines, 18 generator functions +
composition root) into one file per generator under
scripts/resolvers/preamble/. Root preamble.ts becomes a thin composition
layer (~80 lines of imports + generatePreamble).

Byte-identity verification (the real gate per Codex correction):
- Before refactor: snapshotted 135 generated SKILL.md files via
`find -name SKILL.md -type f | grep -v /gstack/` across all hosts.
- After refactor: regenerated with `bun run gen:skill-docs --host all`
and re-snapshotted.
- `diff -r baseline after` returned zero differences and exit 0.
The `--host all --dry-run` gate passes too. No template or host behavior
changes — purely a code-organization refactor.
Test fix: audit-compliance.test.ts's telemetry check previously grepped
preamble.ts directly for `_TEL != "off"`. After the refactor that logic
lives in preamble/generate-preamble-bash.ts. Test now concatenates all
preamble submodule sources before asserting — tracks the semantic contract,
not the file layout. Doing the minimum rewrite preserves the test's intent
(conditional telemetry) without coupling it to file boundaries.
Why now: we were in-session with full context. Codex had downgraded this
from mandatory to optional, but the preamble had grown to 841 lines and
was getting harder to navigate. User asked "why not?" given the context
was hot. Shipping it as a clean bisectable commit while all the prior
preamble.ts changes are fresh reduces rebase pain later.
