core 2850 -> 3000, ext 2000 -> 3500, modules 6 -> 9. ext was the binding one: 1975 of 2000, with syntax highlighting still to write, so for that ceiling this is not anticipation but the difference between building the next feature and not. The other two are bought ahead of a list of features the human has signed for. DEPS_MAX 9 leaves room for chroma and its regexp2 — which fill 6 exactly — plus two more. Worth naming rather than glossing: a ceiling raised on evidence is a measurement, and one raised on intent is a budget. The first two raises were the first kind; this is the second, which is weaker. ADR-0041's test still stands — if core approaches 3000 the question is again what belongs in ext, and the answer is still feed.go and discover.go, waiting on a feature being able to own a route. Invariant 9 is measured by a number that has now moved three times. It says something only because ext rose 75% where core rose 7%. FILE_LOC_WARN and FUNC_LOC_WARN are untouched: they are about one file being readable, and nothing about the plan changes that.

# Growth budgets. `_MAX` fails verify.sh; `_WARN` prints and moves on.

# Only whole-system budgets fail. A hard per-file limit is the one gate whose cheapest fix makes the
|
|
# code worse — sharding a coherent file into a `_helpers.go` turns it green while creating the package

# CLAUDE.md rule 3.6 bans. Total mass cannot be gamed by moving code between files; file length can.

# Two ceilings because "the core stops growing after Arc 2" (architecture.md invariant 9) is only an
|
|
# invariant if something measures it: post-freeze CORE holds and only EXT rises.
|
|
# Costed, not round, and re-costed once (ADR-0041): the first figure covered spine, bundles, queries,
|
|
# render, routing and templates (~1200-1800 → 2000) but never budgeted what cmd/ would hold. Adding `check`
|
|
# ~250, `new` ~100, `-dev` ~100, change detection ~100 and the page cache ~200 to a core already at 1870
|
|
# gives ~2620 → CORE 2800. A second raise is evidence something belongs in internal/ext/, not evidence the
|
|
# number is still too small.
|
|
# Feeds, sitemap, OpenGraph, shortcodes, image sizing, galleries, paging, indieweb ~900-1200 → EXT
|
|
# 2000, deliberately loose since that is where growth belongs. Reaching CORE asks what to delete;
|
|
# reaching EXT asks whether a template would have done it — only .go lines count here.
|
|
# Raised a second time, 2800 → 2850 (ADR-0065), for eight lines of theme contract. ADR-0041 said to read a
|
|
# second raise as evidence something belongs in `ext`: it is, and the candidates are `feed.go` and
|
|
# `discover.go`, which cannot move until a feature can own a route. That is the registry's trigger, not this
|
|
# feature's problem, and the honest fix was not to pretend the contract fits.
|
|
#
|
|
# Raised a third time, and this one is different: 2850 → 3000 core, 2000 → 3500 ext, 6 → 9 modules, all
|
|
# signed off in advance of a list of features rather than in response to one that arrived (ADR-0074). A
|
|
# ceiling raised on evidence is a measurement; a ceiling raised on intent is a budget, and this is the second
|
|
# kind. `ext` was the binding one — 1975 of 2000 with a syntax-highlighting feature still to write.
|
|
#
|
|
# CLAUDE_LOC_MAX is a different kind of budget: every other ceiling here bills once, when someone reads
|
|
# the code, while CLAUDE.md is re-sent on every turn of every session. 150 leaves ~20 lines of headroom
|
|
# over the current file. Reaching it means moving detail to the doc that owns the topic, never deleting
|
|
# a rule to fit — `docs/README.md`'s compression contract governs which of the two you are doing.
