A call is `{{< name key="value" >}}` alone on a line, parsed by a goldmark block
parser into an AST node and rendered by executing a theme template of that name
(ADR-0036). `figure` ships; `include` and `gallery` need the including bundle's
directory, which the parser does not carry yet, so they wait.
The layering did the design work here. internal/render may not import
internal/ext, so render.New takes a callback that receives a Partial and returns
Markdown extensions, and cmd/khosra/wire.go holds the only list of enabled
features. Empty that list and the engine still builds and serves — which is the
property extensions.md says the contract should have.
Raw HTML stays disabled. An author's text reaches a page only as arguments that
html/template escapes in context, which the real binary shows: a hostile alt
becomes <script> and src="javascript:…" becomes #ZgotmplZ. Getting
contextual escaping from the standard library rather than writing it is the whole
reason a fragment renders this instead of the feature.
parseSet became variadic so the fragment set reuses it rather than growing a
second copy of the overlay logic; `Partial` takes map[string]string after the
advisory correctly flagged `any` as generality nothing had asked for.

Serves a bundle at /{section}/{slug}/, a paginated listing per section, tag listings global and
section-narrowed, sequence navigation and a series archive on any nested bundle, and static/ verbatim.
Chrome text, dates and digits render in English or Bengali; authored text is untouched but for typographic
smoothing (ADR-0034). This repo holds engine source only — the site root is external and passed with
-site (ADR-0011).
Frontmatter the parser lifts today: title, date, tags, aliases, order. Every other key in
content-model.md's table — including slug, draft and type — lands in Extra unread, so that table
is the accepted format, not a list of what runs.
Dependencies: three, all allowlisted — goldmark, golang.org/x/text, 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 | 5 | 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 / output formats | 2 | 2 — due | Two template sets exist (bundle, listing); the View layer is Arc 2's third item |
| Effects | 0 | 2 | Effect runner + trigger wiring (change / schedule / demand) |
| Extensions | 1 | 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 | 3 direct | budget in scripts/budgets.env |

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 | 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) |
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 |
| Raw HTML in Markdown is omitted only because goldmark's default omits it | Shortcodes landed without unsafe mode — a call renders through a template instead (ADR-0036), so the feared trigger came and went. What remains is that nothing stops a later change from enabling html.WithUnsafe(), which would silently turn authored Markdown into an injection path |
Now: a gate rejecting WithUnsafe anywhere in the tree, so the rule is mechanism rather than memory |
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.Rootmakes 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 untidygo.modhiding 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.
