go.mod	module khosra; goldmark, x/text, yaml.v3 direct	10
internal/content/doc.go	package comment	5
internal/content/content.go	bundles: os.Root open, walk, frontmatter split, key/lang derivation, NFC, tag slugs, partial files, permalink building	381

internal/content/site.go	the indexed site: lookup with language fallback, aliases, Query and Run, sections, Sequence, Everything, slug routes	395
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	409

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 picture inspection (ADR-0042)	534
internal/ext/widows/	second feature: joins the last two words of a paragraph or heading with a non-breaking space, over the tree so code spans are safe	108
cmd/khosra/wire.go	the only list of enabled features (extensions.md)	20
internal/web/resolve.go	URL → (key, lang, page, tag) or a canonical redirect: language prefix, /en/… fork guard, pagination, tags, trailing slash	112
internal/web/asset.go	files inside a bundle's own directory, looked up through the owning bundle so visibility can only ever inherit (ADR-0024)	58
internal/web/feed.go	Atom for the site, a section or a tag, from dated bundles via one Query (ADR-0043)	125

internal/web/web.go	handler: resolve, look up with fallback, section and tag listings, sequence, /static/ (misses and refusals alike answer 404), degrade on failure	152
cmd/khosra/main.go	flags (-site, -addr, -base, -cache), wiring, startup including the derivative pass — the only place things are assembled	88
*_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, widows, site settings, absolute URLs, robots, sitemap, slug routes, bundle assets, derivatives, feeds, 404	2334

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 and widow prevention (ADR-0034). This repo holds engine source only — the site root is external and passed with -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, shortcodes and widows 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	2	3	Extension registry (extensions.md). The wire file arrived with the first feature rather than the registry — cmd/khosra/wire.go, one line, no struct
Interface implementations	—	2	The interface itself
Non-stdlib dependencies	4 direct	budget in scripts/budgets.env	—

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	No cache exists anywhere yet, and a site of this size resolves in microseconds. Measuring first is the rule (queue 16)	The page cache (queue 16), which is the thing that makes the cost visible

Open questions

None. Nothing blocks Arc 1 or the first deploy.

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.
