A house for sale, an apartment to rent, a car. One document per listing,
on the seller's own origin, so a directory reads the seller's file
instead of licensing somebody else's database or scraping a marketplace
that forbids it.
**The name `OpenRental` was the obvious one and it is taken.** It
already means renting OpenAgent and OpenSwarm members through CoinPay,
with a published schema, SDK, validators and fixtures. Its own document
records surviving one collision already: it was OpenFleet until
2026-09-13. Reusing the name for housing would have broken a shipped
0.1 spec, so the family is OpenListing instead.
Two axes rather than a spec per combination. A house for sale and a
house to rent are the same house; only the offer differs. A house for
sale and a car for sale are the same offer; only the subject differs.
Writing OpenHouseForSale, OpenHouseForRent, OpenCarForSale and the rest
produces one spec per cell of a grid, each repeating most of the others.
So `offer.type` carries sale/rent/lease/auction/free/wanted and
`subject.type` carries property/vehicle, and a subject profile adds only
the fields peculiar to its subject. A reader that knows OpenListing but
not a profile still reads price, location, offer and dates correctly.
`openhouse` is not used as a name: in real estate an open house is a
viewing event, not a kind of listing. An actual one is an entry in
`showings`.
The problem section is grounded rather than asserted: RESO tracks 484
separate MLSs as of August 2026, down from nearly twice that in 2015;
each does publish a RESO Web API feed, and each requires a real estate
licence, a signed per-MLS data agreement and vendor credentials. Four
hundred and eighty-four negotiations for one national view, not
redistributable. Vehicle parts are the same shape with different
letters (ACES/VCdb, TecDoc).
Decisions worth naming. Prices are decimal STRINGS, because 2450.10 is
not representable in binary floating point and a listing is a price.
Absent means unstated, never zero -- with `bedrooms: 0` called out in
the property profile as the one place where zero genuinely differs and a
studio is not an unstated bedroom count. `location.precision` lets a
seller publish a postal code rather than a street for an occupied home,
and forbids a reader from drawing a pin on a building anyway. A closed
listing SHOULD stay served for 90 days with `closed_at`, because a
directory that learns from a 404 cannot tell "sold" from "outage" --
the failure that makes every coupon site a graveyard.
The vehicle profile treats a VIN as a claim rather than a proof, points
readers at NHTSA vPIC (free, keyless, public domain) for decoding rather
than making sellers restate what the VIN encodes, and puts parts fitment
explicitly out of scope: that is ACES/VCdb or TecDoc, and a public spec
cannot restate licensed data.
Registered as one parent and two blocks under it, using the registry's
existing `parent` field the way OpenServer's blocks already do. Flat
slugs rather than nested paths because /docs/[slug] is a single dynamic
segment, not a catch-all -- a nested slug would not have routed at all.
nichedb.dev is named as the reference directory.
50 contract tests pass including spec-discovery and page-metadata.

There is no shortage of places to look up an AI model and nowhere to look
up what it costs you, from the provider that will bill you, in a form a
program can read. Every provider publishes prices as a marketing page and
every comparison site scrapes those pages. The best of them, models.dev,
is a community database: 8,179 provider offerings across 223 providers,
maintained by volunteers reading pricing pages. Good work, and still a
third party writing down what a company charges.
OpenModel is that table served by its author at
/.well-known/openmodel.json: price per million tokens in, out and cached,
context and output limits, modalities, and what each model can do.
The unit is the offering, a provider and a model together, because the
same model reaches a buyer from many providers at many prices and the
price is the question they came with.
Two rules decide what a row means, and both come from measuring the real
data. A published zero is a fact: of those 8,179 offerings, 638 cost
nothing and 424 published no price at all, so a reader that collapses the
two invents a free model or hides one. And absent is unstated, never
false, because a false travels further than a blank and comes back quoted
as a fact.
Origin is the proof, as with every catalog spec here: a file naming a
provider's web and served by somebody else is a stranger's claim about
that company's prices.
The first reader is the models collection at nichedb.dev/c/models, which
reads descriptors beside the models.dev catalogue in the same vocabulary
so one feed catches both.
Registered in the one registry, with docs/openmodel.md and a docs-only
entry (no landing page yet), and added to the spec-discovery contract so
the family page, docs index, llms feeds and sitemap are proven to carry
it.

One openicon.json naming every icon (kebab-case keys, unique aliases,
shared keywords), 24x24 currentColor SVGs with a stated grid, and three
terminal glyphs per icon: a Nerd Font character with its codepoint and
glyph name, a Unicode symbol and a 1-4 character ASCII spelling, picked
nerd > unicode > ascii. Brand logos carry brand: true, a trademark note,
source and licence. made_by + W3C AI disclosure per set and per icon.
Mapping from Lucide, Tabler, Font Awesome, Nerd Fonts and Simple Icons.
Landing page shows 47 icons from the reference set (profullstack/openicon).

One openemoji.json that states coverage against a Unicode version, the
licence, and who or what drew the set (made_by plus the W3C AI disclosure
vocabulary), and glyphs named by fully-qualified codepoint sequence.
Custom emoji get x- keys with shortcodes; skin tones name their base;
rendered emoji keep the character as alt. Mapping from Mastodon, Slack,
Discord and CLDR.
Landing page shows 19 glyphs drawn by the reference implementation,
`emoji` in profullstack/cli-tools.

TITLE / STYLE / EXCLUDE STYLES / LYRICS label blocks with [Section - direction]
tags, no Markdown (Suno reads plain text only). Kept beside the audio as the
same name with .txt, album lyrics.txt with ==== dividers, one-way mapping to
ID3/Vorbis tags. Example is track 002 of Þrøngva, When the Ravens Lied.

OpenObject is a bucket you can mount: keyed objects as ipfile swarms placed
on OpenDisk disks under pay2seed at a stated redundancy (three replicas on
three operators in two countries by default), an ipdb index as the bucket's
clock, a repair loop, an HTTP API, an S3 mapping and a mount whose
consistency is close-to-open by seq. d1sks.com is the reference store.
OpenSlice is a container whose compute is rented from one market and whose
disk is mounted from another: a host descriptor at
/.well-known/openslice.json, one signed slice file (image by digest,
OpenCPU/OpenMemory/OpenGPU units, OpenObject mounts, OpenCreds env, ports,
placement, lifetime), and a reservation that is a paid2seed lease applied to
compute with presence proofs per epoch. slic3s.com is the reference
marketplace; c0mpute hosts take the slice role.
Both are registered under OpenServer in the catalogs family with landing
pages, rows in the OpenSwarm family table, and the spec-discovery contract.
llms.txt now cites the specification URL for child specs too, which every
block under OpenServer had been missing.

A new LogicSRC spec in the catalogs family. One heading, an identity block
(Kind, Web, Repo, Operator, License, Extends, Updated), one line, then eleven
layers: Languages, Runtimes, Interfaces (one ### per way in: web, api, cli,
tui, mcp, desktop, mobile, worker, extension, bot), Data, Services, Modules,
Tooling, Hosting, Auth, Conventions, Not. An item is one bullet: name,
version, an optional status word (trial, hold, leaving) and a role. Extends
inherits a parent file, sections replace, Conventions and Not accumulate.
Rule 8 is the reading rule for agents: use what is listed, prefer listed
over new, ask before adding a layer or a service, never add a Not, keep the
file true. Discovery at OpenStack.md in the repo, /.well-known/openstack.md,
rel=openstack, or a platform path. JSON is derived and never the source.
logicsrc.com serves its own at /.well-known/openstack.md: the route extracts
the worked example from docs/openstack.md, and a contract test holds the two
together and checks the file follows its own rules. rel=openstack in <head>
and in the Link header beside openprofile.

OpenWiki writes down what the [[Page]] convention already is in practice,
so a wiki can be moved, mirrored, read by a directory and edited by an
agent without reading any engine's source. One Markdown file per page
with a small optional front matter (title, aliases, tags, summary,
author, made_by, disclosure, created, updated, license, lang, redirect);
wikilinks resolved by exact name, loose name, alias, path, then wanted;
one address with three representations (rendered, .md, .md?rev=) and a
history.json per page; a descriptor at /.well-known/openwiki.json with
pages_url, changes (Atom), repo, edit, editors and accepts; editing as
PUT of the same file with If-Match on the revision; discovery; what a
directory owes a wiki. Every revision says who made it: human, ai or
both, the same word OpenWebring uses.
A folder that follows it opens unchanged in Obsidian and Logseq, and any
such folder becomes an OpenWiki by adding the two files. The first host,
goviral.wiki, is being built on it.

OpenL10n is the record of what a file says, in any language: one
transcript per media per language, addressed by the OpenFile id (or a
url: or live: identity for what has no bytes), lines as seconds into the
media, a translation kept beside the original and marked with what it
came from, complete or heard in pieces, made once on request with 202
progress, served as JSON, SRT, VTT or text.
OpenI18n is one file a service serves at /.well-known/openi18n.json
about the languages it speaks: which, which it can turn into which, how
to ask for one, and where texts are translated, with limits, models and
the pivot said out loud.
Both are what nixamp 0.24 and 0.25 serve today, written down so anything
that hears or translates can keep the same record.

PR 177 shipped a second OpenFleet under the same slug: a published listing of OpenAgent profiles and ipfile swarms with CoinPay rental offers. Anthony ruled that OpenFleet means the human-controlled fleet and the record of who spawned whom, so the rental contract is renamed OpenRental (slug openrental, catalogs family, group noun listing): docs/openrental.md, logicsrc-openrental.schema.json with type logicsrc.openrental and scope kind listing, fixtures/openrental, createOpenRental and OpenRental* types in the SDK, the openrental validator kind. Minor bumps because an export moved: @logicsrc/schemas 0.2.0, @logicsrc/validators 0.2.0, @logicsrc/sdk 0.2.0. The discovery contract test now covers openfleet, openrental and openwall, one per family, and accepts a landing-page link in llms.txt.

One file a ring serves about its members, one file a member may serve
about itself, plain links between them, and a made_by declaration on
every member (human, ai, both) so a reader can follow the human web or
the machine web on purpose. Six hop rules that accept every addressing
shape rings already use (?from=, ?host=, ?via=, ?url=, a slug in the
path, the bare Referer), so a member of any existing ring joins with no
change; verification the IndieWeb way (mark inactive, never delete); an
OPML twin of every ring; no script, no tracking, no central registry.
Name: OpenRing is Drew DeVault's tool in this exact niche and every
openring domain is taken; OpenWebring has only a dead 2020 predecessor
and free domains. Registered in the catalogs family.
First host: rssamplifier.com/ring (one ring per topic), in flight.

A new spec at /openfleet and /docs/openfleet replacing the AgentSwarm placeholder. A fleet is every agent session one human answers for; a swarm is the members one spawner starts inside it for one task. One record per session (claimed by the first session that writes its member.start, derived when inherited), one append-only ledger per fleet per host with eight events, five sysop verbs, fifteen rules, and what Claude Code and moshcode would each add. Written from job 172ffd83, which had to reconstruct its own parentage by hand.
openswarm keeps its slug (it is the peer-to-peer media family) and gains a one-line pointer. /agent-swarm redirects permanently to /openfleet; the registry entry, home band, catch-all route and scroll hook for the placeholder are replaced or removed. Contract test covers the redirect.

Every consumer of a link reads a page's card tags its own way, caches the
first reading for days, and publishes nothing. OpenSite writes the reading
down: a record per URL (title, description, image, kind, canonical, author,
feeds, the card tags verbatim, JSON-LD as parsed), a descriptor a site
serves at /.well-known/opensite.json, the order a reader takes each field
from a page, the four calls an index offers, and a table of what each
consumer reads and caches.
docs/opensite.md, one entry in the specs registry (catalogs family), and a
landing page at /opensite. The first index is nichedb.dev/c/sites; the
first publisher is nixamp's share links.

Subscribing takes one click and cancelling takes a support ticket, and no
reader can check that the two are as easy as each other because the way
out is not written down anywhere a reader can fetch. The service already
has a plan table, a cancel endpoint and a refund rule. OpenSaaS is those
at /.well-known/opensaas.json: plans, and eight actions (subscribe,
cancel, pause, resume, change_plan, unsubscribe, export, delete), each
as the page a person opens and the endpoint an agent calls with an
OpenAccess scope, with steps and confirm as the exit measure a directory
shows beside the entrance. Doc, landing page, registry entry under
catalogs. nichedb.dev is named as the first directory and the first
service.

The SimpleFIN door written down for anything a bridge holds: a person gets
a single-use setup token from the bridge, pastes it into an app, the app
claims it once for an access URL and a bearer the bridge can revoke. No
client registration, no redirect, no key for the app to keep, which is what
a browser extension or a script needs. Bearer instead of SimpleFIN's Basic
credentials in the URL, because a browser's fetch refuses those. Eight
rules, the social profile (accounts, analyze, write, suggest, activity,
posts only when declared) and the finance profile (SimpleFIN, unchanged).
First bridge: mynaposter.com (/connect). First app: DefPromo. Registered
as one entry in the specs registry under Access and credentials, beside
OpenAccess, which is the registered door with the same scope vocabulary.

Anthony: "that site needs better information architecture, it's impossible
to find anything", "start broad in sidebar and drill down with dedicated
pages, not all one page", and "I see none of our specs" on the home page.
One registry, lib/specs.ts, now lists every specification in four
families (people and agents; access and credentials; catalogs a site
serves about itself; agents and process), with a landing path, a
specification path and, for OpenServer's blocks, a parent. Everything
that lists specs reads it: the sidebar (lib/nav.ts, four groups: Start,
Specs, Tools, Company, rendered by SiteShell and by the home page string
from the same array), /specs and /specs/<family>, the home page's
Standards Surface grid (families with their specs, replacing the five
abstract primitives), /docs (grouped by family, then guides), the sitemap
and llms.txt. DOC_SLUGS is derived from the registry. Adding a spec is
one entry plus its files; the four hand-kept lists are gone.
