**Verified against:** `8a6857b` on 2026-07-30 — update this line every change.
If this file disagrees with the code, the code is right and this file is a bug.

## 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.
