internal/content/clock.go	the one place the engine reads the wall clock, which verify.sh enforces by filename	12
internal/content/settings.go	site.yaml: the site's own declarations (base, title) and absolute-URL building (ADR-0039)	59
internal/content/site.go	the indexed site: lookup with language fallback, aliases, Query and Run, sections, Sequence, Everything, slug routes, publication visibility	424
internal/render/render.go	goldmark with the typographer, per-kind template sets with site override, the Partial/Origin seams features render and resolve through, Page/List/Sequence/head	459
internal/render/chrome.go	the engine's own words: phrase table, month names, digits, and the t/num/day template funcs (ADR-0034)	105
internal/render/templates/	reference theme: base.html, page.html, list.html, shortcodes.html, theme.css (ADR-0026)	—
internal/ext/shortcodes/	first feature: {{< name key="value" >}} block parser and node renderer, rendering through a theme fragment (ADR-0036). figure, gallery, include, plus the derivative pass and remembered picture inspection (ADR-0042, ADR-0044)	564
internal/ext/scaffold/	writes a new bundle into the site root through os.Root: a directory bundle, a draft, never an overwrite	102

cmd/khosra/main.go	flags (-site, -addr, -base, -cache, -dev), wiring, startup including the derivative pass. main dispatches subcommands, runServe assembles the server — still the only place anything is wired	116
cmd/khosra/check.go	the check subcommand: parse, print, exit code. What counts as a finding lives in the feature	45
cmd/khosra/new.go	the new subcommand: arguments in either order, then the feature does the writing	42
*_test.go	table-driven, one file per source file; symlink escape (content and static), canonical paths, language fallback, aliases, pagination, tags, sequences, chrome, typography, shortcode escaping, galleries, includes, partials, site settings, absolute URLs, robots, sitemap, slug routes, bundle assets, derivatives, feeds, 404, plus benchmarks for the render path and the checker, unpublished visibility, listing shapes, scaffolding	2732

Serves a bundle at /{section}/{slug}/ — the slug derived, or declared in frontmatter without moving the key (ADR-0035) — a paginated listing per section, tag listings global and section-narrowed, sequence navigation and a series archive on any nested bundle, static/ verbatim, a directory bundle's own files under its URL, generated derivatives under /derived/, Atom feeds per site, section and tag, plus /robots.txt and /sitemap.xml. Chrome text, dates and digits render in English or Bengali; authored text is untouched but for typographic smoothing (ADR-0034); line breaking is left to CSS (ADR-0045). This repo holds engine source only — the site root is external and passed with khosra check validates a site root and exits non-zero on anything that makes it wrong; khosra new scaffolds a draft bundle into one. A draft or future-dated bundle is not served at all — nor is any file inside it (ADR-0024) — until -dev on reveals it and reloads templates per request. -site (ADR-0011). site.yaml declares base and title; with a base, canonical, hreflang and OpenGraph URLs go absolute (ADR-0039).

Frontmatter the parser lifts today: title, date, tags, aliases, order, slug. Every other key in content-model.md's table — including draft and type — lands in Extra unread, so that table is the accepted format, not a list of what runs.

Dependencies: four, all allowlisted — goldmark, golang.org/x/text, golang.org/x/image, gopkg.in/yaml.v3.

Counters — the earn-it authority

Never anticipate a threshold. Increment when the code lands, then check whether the extraction is due this change.

Counter	Now	Extraction due at	What it buys
Render transforms — page-level only	0	3	Stage pipeline (ordered func(ctx,*Page) error). Parse-phase work does not count and must not: goldmark's extender list is already an ordered pipeline for it, so typography and shortcodes compose there (cmd/khosra/wire.go) and a second pipeline beside it would be pure duplication. This counts transforms over the assembled page, which nothing hosts yet — OpenGraph and JSON-LD (queue 15) are the first candidates
Routing cases	9	2 — done	Resolver at internal/web/resolve.go: bundle, language prefix, pagination, tag, section-narrowed tag
Collection pages	4	1 — done	Query primitive: content.Query{Section, Tag, Lang} + Site.Run. The fourth — a series archive — resolves through Site.Sequence instead: membership is structural and the sort ascends, so it shares the index but not the Query
Views — per-bundle selection only	0	2	The View layer architecture.md describes: view: in frontmatter choosing a presentation, resolved through the cascade. Nothing selects a view yet. Output formats are counted separately and are not it: HTML, sitemap XML and Atom are three functions with nothing to share — an interface over them would have one member and no leverage
Effects	1	2	Effect runner + trigger wiring (change / schedule / demand). The first is the derivative pass (ADR-0042), called straight from cmd at startup — one call needs no runner, and startup is the only change signal until queue 21
Extensions	3	3 — due, and the answer is still no	Extension registry (extensions.md). It reached 3 once before and went back to 2 when the widows feature was deleted (ADR-0045) — a threshold reached by a feature that should not exist was never a threshold. It is 3 again with scaffold, and the note below the table says why a registry still buys nothing
Interface implementations	—	2	The interface itself
Non-stdlib dependencies	4 direct	budget in scripts/budgets.env	—

The Extensions counter is due, and a registry would still buy nothing. The three features attach in two unrelated ways: shortcodes is a goldmark extender listed in extenders(), while check and scaffold are functions cmd calls for a subcommand. A registry would have to abstract over "extends Markdown", "validates content" and "writes a file", which share nothing but the word feature — one member and no leverage. What the counter is really detecting is that two of the three are commands, and commands compose fine as a switch in main. Build the registry when a feature wants a route (the seam ADR-0042 named) or when two features need to agree on an order.

Allowlist, all four imported: goldmark (markdown), golang.org/x/text (NFC, ADR-0015), gopkg.in/yaml.v3 (frontmatter, ADR-0020), golang.org/x/image (resampling and WebP, ADR-0040).

Latent items — known, deliberately unfixed

Do not fix these mid-feature. They become features when the human says so. An arc does not close with an untriaged item: at each arc boundary every row is fixed, scheduled into an arc, or accepted with a stated reason. A list nothing drains is a graveyard of known defects.

Item	Why it waits	Trigger to fix
No mechanical check that the counters are correct	Accepted at the Arc 1 boundary: the coupling gate makes forgetting them impossible, which is the real failure mode, and checking the values needs code to count	The first page-level transform (queue 15), now that the transform counter means something narrower
No mechanical gate on the untrusted boundary (ADR-0003)	Scheduled to Arc 3: nothing untrusted is read yet. Half of it is now mechanical — verify.sh rejects WithUnsafe, so authored Markdown cannot become HTML — but there is still no check that a future untrusted source stays out of shortcode and template evaluation	The comment path — a test that untrusted input reaches no shortcode or template evaluation
date stays in Extra after being lifted onto Bundle.Date, unlike title, aliases, tags and order, which are deleted	Spotted while adding order; the theme contract says Extra holds what the parser does not name, so one of the two is wrong. Harmless today — a template reading .Extra.date gets the raw YAML value	Whatever next reads Extra generically: feeds (queue 14) or check (17)
A gallery's images carry no alt	width/height now come from the original (ADR-0042), so only alt text is missing, and a filename does not supply one. An empty alt is honest for a picture the page has already introduced	Captions per gallery entry — a sidecar or a frontmatter list — if the reference theme ever needs them
Sequence resolution rescans the index on every bundle request — two passes over every key, each doing a Lookup	Measured at the same time as the pictures (ADR-0044): a whole page is ~63µs, so this is not what costs anything. Remembering it would be a cache with no measurement behind it	A page render exceeding a few milliseconds, which is also what would revive the parked cache model
The picture memo is never evicted — one entry per picture on the site, for the life of the process	Correct for one author's site, and the alternative is an eviction policy nothing needs. It is keyed on size and modification time, so it cannot go stale, only grow	A site root large enough that memory matters, or a long-running process where pictures churn

Open questions

None. Nothing blocks Arc 1 or the first deploy.

Every feature has been audited against the layer test (ADR-0046). One was wrong and was deleted (widow prevention, ADR-0045); one quietly decided presentation and now offers both shapes (tag listing grouping). The verdict table is in the ADR, and remaining queue entries carry a layer note before they are built.

Every ADR in decisions.md is accepted; none is open or proposed.

Build queue

Working plan lives in .scratch/build-queue.md, which is deliberately not committed — git log is the record of what actually landed. If that file is absent, read the log and rebuild the plan from it.

Arc retro log

One line per completed arc: what it cost, what it taught, what it made unnecessary.

• Arc 1 — the spine. 619 core lines, 3 dependencies, 4 queue entries. Taught: os.Root makes the path guard a property of the type, so the latent item that shipped with the harness died instead of being implemented; and running the gates against real code found six defects in the gates — an allowlist parser that rejected its own documented format, two advisories that fired only on correct code, a coupling gate that demanded explanations for permission edits, an untidy go.mod hiding a direct dependency, and a nesting check off by one level. Made unnecessary: a hand-rolled traversal cleaner, and a second routing branch — the resolver arrived by counter at exactly the right moment.
