Inventory

File	Purpose	LOC
go.mod	module khosra; x/text, yaml.v3 direct	8
internal/content/content.go	site root → bundles: os.Root open, walk, frontmatter split, key/lang derivation, NFC, collision drop, key index, language fallback, alias index, URL building	358
internal/render/render.go	goldmark + the embedded reference theme; Page is what templates receive	92
internal/render/templates/	reference theme: base.html, theme.css (ADR-0026)	—
internal/web/resolve.go	URL → (key, lang) or a canonical redirect: language prefix, /en/… fork guard, trailing slash	56
internal/web/web.go	handler: resolve, look up with fallback, render, degrade on failure	62
cmd/khosra/main.go	flags, wiring, startup — the only place things are assembled	50
*_test.go	table-driven; symlink escape, permalink, redirect, 404	245

Serves a bundle at /{section}/{slug}/. This repo holds engine source only — the site root is external and passed with -site (ADR-0011).

Dependencies: none.

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	0	3	Stage pipeline (ordered func(ctx,*Page) error)
Routing cases	2	2 — done	Resolver extracted at internal/web/resolve.go
Collection pages	0	1	Query primitive
Views / output formats	1	2	View layer (contract per theme-contract.md)
Effects	0	2	Effect runner + trigger wiring (change / schedule / demand)
Extensions	0	3	Extension registry + wire file (extensions.md)
Interface implementations	—	2	The interface itself
Non-stdlib dependencies	3 direct	budget in scripts/budgets.env	—

Allowlisted, in use: goldmark is not yet imported. Allowlist: goldmark (markdown), golang.org/x/text (NFC, ADR-0015), gopkg.in/yaml.v3 (frontmatter, ADR-0020).

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	3rd transform (queue 12)
No mechanical gate on the untrusted boundary (ADR-0003)	Scheduled to Arc 3: nothing untrusted is read yet	The comment path — a test that untrusted input reaches no shortcode or template evaluation
Raw HTML in Markdown is currently omitted only because goldmark's default omits it	Verified at the Arc 1 boundary, and it is what keeps invariant 2 intact for authored content. html.WithUnsafe() is the obvious move when a shortcode needs to emit HTML, and it silently turns authored Markdown into an injection path	Shortcodes (queue 12) — if unsafe rendering is enabled, the trusted/untrusted split must be real code, not a default

Open questions blocking Arc 1

None. Every decision the engine needs before Arc 1 and before the first deploy is recorded.

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.
