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.
`::toc` renders through a `toc` fragment receiving level, text and the id
goldmark already assigns. The engine collects, the theme decides whether that is
a list, a sidebar or nothing — the reference theme emits a flat <ol> with a
level class per entry, so indentation is CSS rather than markup.
A theme cannot enumerate headings, because templates cannot parse HTML, so the
engine is the only thing that can supply them. Collection lives in ext; only the
Heading type and one Fragment field are core.
That is what needed the ceiling: CORE_LOC_MAX 2800 -> 2850, the second raise.
ADR-0041 said to read a second raise as evidence something belongs in ext, and
the test was applied rather than waived. feed.go and discover.go are the
features that should leave core, and they cannot, because an ext feature cannot
own a route until the extension registry exists — which the counter says buys
nothing yet. The thing that should move is blocked on a different decision, so
the honest fix was the ceiling and an ADR saying exactly that. When routes
become ownable, they leave and this comes back down.
Entry text is the heading's words with markup stripped: a link inside a link is
not markup a browser accepts. An entry whose heading has no id is skipped rather
than linked nowhere, and a page with no headings renders no nav at all.
core 2804/2850, ext 1825/2000, 34 gates green, 0 warnings.
Adopts ideas/token-conservation.md, parked 2026-07-28, plus the disciplines
the human added: read the compressed form first, discover by mechanism,
shrink output at the source, never pay twice for the same bytes.
docs/context-economy.md owns all of it and leads with a floor, because
every cheap failure mode is also a token saving — skipping the owning doc,
guessing a signature, reporting from a diff, thinning a test — and each has
already cost this repo a defect. Frugality is for presentation and
discovery, never for the artifact or the evidence.
Mechanical, not remembered:
- scripts/surface.sh generates docs/surface.md — every top-level
declaration with its line, 261 lines standing for 3757 of source. The
pre-commit hook regenerates and stages it, so it cannot be stale, and
verify.sh compares independently for a clone that never set
core.hooksPath. The hook refuses a commit with unstaged .go changes,
since what it generated describes the working tree, not the commit.
- verify.sh --quiet: 48 lines of gate output become 1. The hook uses it.
- CLAUDE_LOC_MAX=150, the only budget billed per turn rather than per read.
Both new gates were watched failing before being kept: a doctored
surface.md, and CLAUDE_LOC_MAX temporarily set to 5.
state.md's inventory loses its LOC column. It had already drifted on six
files (content.go 381→450, render.go 447→454, web.go 206→217, check
216→223, watch 129→137, chrome 105→110) which is what a number written in
two places does; the generated file owns sizes now, the table owns purpose.
The subagent question is recorded there as the one open decision, with the
case for and against written out in the idea file.
ADR-0040 puts the dependency approval on the record, as hard rule 2 requires: the
standard library decodes JPEG, PNG and GIF but cannot resize, and image/draw
scales only by nearest neighbour, which is visibly wrong on the photographic
downscales this site is made of. Four modules against a cap of six, no transitive
dependencies, and WebP decoding comes along. AVIF still has no decoder anywhere,
so it will pass through untouched.
ADR-0041 raises CORE_LOC_MAX 2000 → 2800. The old figure was costed before any
code existed, for the spine and the render path, and never budgeted what cmd/ will
hold: `check` ~250, `new` ~100, `-dev` ~100, change detection ~100, page cache
~200. On a core already at 1870 that is ~2620 before anything optional, so the gate
was going to fail work nobody would call excess. A costing error corrected, not
discipline loosened.
The ADR and HARNESS.md both say what a *second* raise would mean: that something
belongs in internal/ext/. Two ceilings exist so "core stops growing, ext rises" is
observable, and that stops being true the moment leaves are let into core.
