khosra/harness/state.md

State

Currency is compared, not declared. verify.sh warns unless this file's last commit is at least as new as the last commit touching .go, so it ships inside the change it describes — no sha to write, and no trailing commit to write one (ADR-0057). If this file disagrees with the code, the code is right and this file is a bug.

Inventory

The engine- and agent-facing docs live in harness/, not docs/ (ADR-0082). docs/ is reserved for documentation aimed at whoever uses khosra and does not exist yet — an end-user documentation site is planned, with its home and whether its claims are gated both undecided.

Line counts are not here: harness/surface.md is generated from the code and carries per-file sizes plus every declaration's location (ADR-0053). This column drifted on six files before it was removed, which is what a number written in two places always does. What each file is for is the fact this table owns.

File	Purpose
go.mod	module khosra; goldmark, x/text, yaml.v3 direct
internal/content/doc.go	package comment
internal/content/content.go	bundles: os.Root open, walk, frontmatter split, key/lang derivation, NFC, tag slugs, partial files, permalink building
internal/content/clock.go	the one place the engine reads the wall clock, which verify.sh enforces by filename
internal/content/extras.go	a bundle's supporting files: enumeration, classification, and their URLs (ADR-0047)
internal/content/settings.go	site.yaml: the site's own declarations (base, title) and absolute-URL building (ADR-0039)
internal/content/site.go	the indexed site: lookup with language fallback, aliases, Query and Run, sections, Sequence, Everything, slug routes, publication visibility
internal/render/render.go	goldmark with the typographer, per-kind template sets with site override, the render methods. A Renderer never changes after New: a rebuild builds a new one and it is swapped with the index as a single web.Snapshot, so no page is assembled from two of them (ADR-0055, ADR-0056, ADR-0077). Heading ids are a parser option set here, declared or derived (ADR-0058, ADR-0066), and this is the one renderer that enables raw HTML (ADR-0060). Compose is the seam a merging bundle's splice arrives through
internal/render/view.go	the theme contract in Go, and now actually all of it: Page (with Assets, Styles and Scripts — the assets a page's own calls and use: asked for, ADR-0079), List, Sequence, Extras, Item, Partial, Fragment (with Body, Headings and Lang — ADR-0064, ADR-0065, ADR-0067), Heading, Picture, Origin
internal/render/chrome.go	the engine's own words: phrase table, month names, digits, and the t/num/day template funcs (ADR-0034), including the words a shortcode fragment supplies when the author gives none (ADR-0067)
internal/render/templates/	reference theme, complete (six icon names map to Unicode, no assets — ADR-0063): base.html (shell, navigation, language links, feed and OpenGraph), page.html (bundle, sequence, tags, extras), list.html, extras.html, shortcodes/ — seven fragment files rather than one, and a site may use either form (ADR-0071) — with the sizes its own layout implies (ADR-0068), theme.css (ADR-0026, ADR-0049)
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, bounded and least-recently-used in memo.go (ADR-0042, ADR-0044, ADR-0073). FootnotePrefix namespaces an included file's footnote ids (ADR-0058). Directive syntax since ADR-0059, plus icons.go: :name: inline, rendered by the theme's one icon fragment (ADR-0063), containers.go: :::name{…} … ::: wrapping a rendered body (ADR-0064), toc.go: the document's headings for a ::toc call, to a depth the call may set (ADR-0065, ADR-0066), and code.go: chroma highlighting, a fence's options, and snippets read from a file (ADR-0075). Merge splices includes before the parse for a bundle that asks for it (ADR-0066)
internal/ext/notation/	the inline marks CommonMark lacks: ~sub~, ^sup^, ==mark==, and ~~strike~~, which it owns so a single tilde can mean subscript (ADR-0061). abbr.go adds *[TERM]: definitions and the pass that expands them (ADR-0062)
internal/ext/scaffold/	writes one draft directory bundle into a site root through os.Root: never an overwrite
internal/ext/watch/	polls content/ and templates/ on an interval it is given, ignores editor droppings, and reports a settled change (ADR-0022, ADR-0048, ADR-0056). site.yaml is deliberately not fingerprinted (ADR-0055)
internal/ext/passthrough/	fifth feature, and the first to own a route (ADR-0081): files in root/ served at the exact path they occupy, .tmpl rendered as text with the site's own settings, headers declared per path in root/_headers.yaml, underscore-prefixed names not addressable
internal/ext/check/	third feature: validates a site root — what the engine worked around, broken internal links, missing titles and alt text, mixed series ordering, and calls left in the retired shortcode form (ADR-0059)
cmd/khosra/wire.go	the only list of enabled features (extensions.md) — extenders() for the ones goldmark composes and routes() for the ones owning a URL path (ADR-0081), the theme function that builds the renderer this build ships (ADR-0072), and the Markdown dialect with it — tables, footnotes, definition lists, strikethrough, task lists (ADR-0058, ADR-0078)
internal/web/resolve.go	URL → (key, lang, page, tag, feed, extras) or a canonical redirect
internal/web/extras.go	the extras route: listing, one entry selected, or ?raw bytes, all behind the bundle lookup
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)
internal/web/feed.go	Atom for the site, a section or a tag, from dated bundles via one Query (ADR-0043)
internal/web/discover.go	/robots.txt and /sitemap.xml, absolute and only with a declared base (ADR-0039)
internal/web/web.go	handler: Snapshot pairs the index with the theme that was current with it (ADR-0077); serve dispatches by kind, serveBundle answers the commonest one; listings, /static/, /derived/, degrade on failure. Mounts the exact paths features own, skipping any the engine already answers — a duplicate pattern would panic (ADR-0081)
cmd/khosra/main.go	flags (including -poll, zero to stop watching), wiring, startup, the derivative pass, and the one atomic swap a change goes through, theme and index together in rebuilder (ADR-0077). main dispatches subcommands, runServe assembles the server, rebuilder is used at startup and on every change alike
cmd/khosra/check.go	the check subcommand: parse, print, exit code. What counts as a finding lives in the feature
cmd/khosra/new.go	the new subcommand: arguments in either order, then the feature does the writing
*_test.go	table-driven, one file per source file — shortcodes has one each for icons, containers and the contents list; 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, extras, change detection, what a page can reach, the root listing, and the example site end to end — that last one in cmd/khosra, beside the wiring it proves (ADR-0072)

root/ in the site root is served at the URL root: root/pubkey answers /pubkey, a .tmpl suffix renders the file as text with the site's own settings and is dropped from the address, and root/_headers.yaml declares headers per exact path (ADR-0081). Paths the engine already answers are skipped and logged.

A page carries only the CSS and JS its own shortcode calls or its use: list asked for, rendered once each from the theme's assets:<name> fragments, plus its own styles/scripts files — bundle-relative, anything climbing out dropped (ADR-0079, ADR-0080). The reference theme emits the stylesheets and no <script> at all, which verify.sh enforces; examples/demo-site redefines the head block to add the tag, so the one JavaScript exception is demonstrated by a site rather than built into the binary.

Serves a listing of everything at / (ADR-0050), 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, a bundle's extras as a browsable tree, plus /robots.txt and /sitemap.xml. Markdown is CommonMark plus tables, footnotes, definition lists, heading ids, task lists and the inline marks (~sub~, ^sup^, ==mark==, ~~strike~~, *[TERM]:), and nothing else (ADR-0058, ADR-0061, ADR-0062, ADR-0078); HTML an author writes renders, because the site root is trusted (ADR-0060). 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 running server notices changes under content/ and templates/ by polling — -poll, zero to stop — and swaps both the index and the parsed theme atomically, so a content or template edit appears without a restart and every page updates together (ADR-0022, ADR-0055, ADR-0056); site.yaml applies at startup only. 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 polls four times a second (ADR-0056). -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, draft, styles, scripts, use. include: embed is read from Extra by the renderer; merging is the default (ADR-0066, ADR-0076). Every other key in content-model.md's table — including type — lands in Extra unread, so that table is the accepted format, not a list of what runs.

examples/demo-site/ is a complete site kept in the repository to be read and served — 31 bundles across six sections, one case per feature in TestTheExampleSiteExercisesEveryFeature, and khosra check run over it by verify.sh (ADR-0051). make demo serves it. Features are spread across the bundles where a real site would put them rather than piled on one page: text marks and the margin note on writing/typography, icons and panels on pages/colophon, the include, table, glossary and contents list on writing/notes-on-water.

A Dockerfile ships the binary alone: the site root is a mounted volume, never copied in (ADR-0010, ADR-0011).

Dependencies: five direct, all allowlisted — goldmark, golang.org/x/text, golang.org/x/image, gopkg.in/yaml.v3, chroma (ADR-0075); six modules of nine with regexp2 indirect.

Counters — the earn-it authority

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

Every row states what does not count. Four of these counters had to be re-scoped on first contact — transforms, views, effects, extensions — because each measured a symptom rather than the mechanism, and the re-scoping was always a sentence about what had been wrongly included. Writing that sentence up front is the cheapest way to find out whether a counter means anything, so the column is required and verify.sh fails on a row that leaves it empty (ADR-0070).

Counter	Now	Extraction due at	What it buys	Does not count
Render transforms — page-level only	0	3	Stage pipeline (ordered func(ctx,*Page) error). This counts transforms over the assembled page, which nothing hosts yet — OpenGraph and JSON-LD (queue 15) are the first candidates	Parse-phase work. goldmark's extender list is already an ordered pipeline for it, so typography, shortcodes and notation compose there (cmd/khosra/wire.go); a second pipeline beside it would be pure duplication
Routing cases	11	2 — done	Resolver at internal/web/resolve.go: bundle, language prefix, pagination, tag, section-narrowed tag	An exact path a crawler asks for by name. /robots.txt and /sitemap.xml are mux entries because no bundle can collide with them, so they never reach the resolver
Collection pages	4	1 — done	Query primitive: content.Query{Section, Tag, Lang} + Site.Run	A series archive. Membership is structural and the sort ascends, so it resolves through Site.Sequence — sharing 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. 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 only one is the derivative pass (ADR-0042), called from cmd inside rebuilder, so it already answers both triggers it will ever need — startup and a settled change (ADR-0048)	An in-memory swap. Replacing the index or the theme re-reads the site root into memory, writing no artifact and calling nothing outbound (ADR-0055)
Extensions	6	3 — passed, and the registry is now partly built	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. The note below says which field was built and why the rest were not	An upstream extension enabled in the list. Table, Footnote and DefinitionList are goldmark's, so they are dialect rather than features of this engine (ADR-0058) — only a package under internal/ext/ counts
Interface implementations	—	2	The interface itself	An interface this repo did not declare. Satisfying fs.FS, http.Handler or goldmark.Extender is using somebody else's abstraction, which is the opposite of inventing one
Non-stdlib dependencies	4 direct	budget in scripts/budgets.env	—	The standard library, and a dependency's own test-only modules — go list -m all shows those, and the gate counts require entries instead (scripts/budgets.env)

The registry's trigger fired, and exactly one field of it was built (ADR-0081). The note below stood for five features and was right until passthrough wanted a route — the condition its own last paragraph named. What exists now is Routes: a feature returns map[string]http.Handler from wire.go, core mounts it, and nothing else from extensions.md's struct was built, because the other six fields have no implementor. The reasoning that kept the rest unbuilt is unchanged and still applies:

Counted by hand this change and found wrong. The row read 4 while five packages existed — notation landed (ADR-0061, ADR-0062) and the count was never incremented, though the prose below already named all five. Six now, with passthrough. This is the latent item about the counters having no mechanical check, demonstrating itself; the count is authoritative only because someone just ran ls internal/ext/.

A registry over the other attachment points would still buy nothing. The six features attach in four unrelated ways: shortcodes and notation are goldmark extenders listed in extenders(), check and scaffold are functions cmd calls for a subcommand, watch is a goroutine, and passthrough hands back a map of URL paths. A registry would have to abstract over "extends Markdown", "validates content", "writes a file" and "polls a directory", which share nothing but the word feature — one member and no leverage. Adding notation made this clearer rather than more urgent: two goldmark extenders compose in goldmark's own extender list, which is already the registry for that shape, and they need no order relative to each other because one is inline and the other block. A feature wanting a route was the recorded trigger and it has now fired, which is why Routes exists and nothing else does. Build the next field when two features genuinely need to agree on an order that no existing mechanism expresses, or when one of the remaining six gets a second implementor.

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 mechanical in a different way since ADR-0060 — verify.sh requires html.WithUnsafe() in exactly one file, so a second pipeline trusting its input cannot appear unnoticed — 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
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 root listing's <title> repeats itself — "A Khosra Demo · A Khosra Demo"	Spotted 2026-08-01 by looking at the served page, not by any test: base.html joins page title and site title unconditionally, and at the root those are the same string. Cosmetic, and the fix is one if in a template — theme layer, not engine	The next time base.html is edited for any reason — its old trigger named queue entry G4, which has been dropped
khosra check cannot report a root/ file shadowing an engine path	The knowledge lives in internal/ext/passthrough/, and verify.sh fails a feature that imports a sibling — so check would need the reserved paths moved into a shared package for a cosmetic gain. The startup warning fires on every boot and cannot be missed, which is louder than a check finding anyway (ADR-0081)	A second feature owning routes, at which point reserved paths stop belonging to one feature and want a home of their own
A draft member's absence from a sequence has no test	Proven by hand against the real binary on 2026-08-02 — a three-chapter series with a draft middle lists two members, prev/next closes over the gap, and the draft 404s. It holds by construction: members() resolves through Lookup, which is the one place ADR-0024 hides unpublished bundles, so there is no second code path to drift	The first change to members(), or to how Lookup decides visibility
Under include: embed, a fragment's footnotes render where the include sits, so a long one puts an <hr> and a numbered list mid-article	Spotted 2026-08-01 by looking at the served page, not by any test. It is ADR-0038's documented consequence, and the ids are correctly namespaced (ADR-0058); only the placement reads badly. Merging is the default since ADR-0076, so this is now something an author opts into by asking for containment	Nothing: it is the documented cost of the model you chose

Open questions

Answered 2026-08-02: no subagents. Read-heavy sweeps stay in the main window. The case for and against is in ideas/token-conservation.md; the decision is that a verdict arriving without the reading behind it cannot be audited, which is the thing this harness is built to make possible. Nothing blocks on it.

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/continue.md, which is deliberately not committed — git log is the record of what actually landed, and the handoff is read against the log rather than instead of it (harness/README.md). 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.
