§ 5.2 properties can carry apps[] (platform, bundle, storeurl, domain), keyed as the OpenRTB 2.6 app object where one exists. Each property must carry domains, apps or both. The CTV example carries an app. Refs IABTechLab#15
§ 5.6 defines floor as the seller's offer floor at proposal time, not the downstream auction floor and not a guarantee that bids will clear. Editorial: the meaning of the field is unchanged. Refs IABTechLab#16
Without apps[].domain a buyer has nothing to run the app-ads.txt check against. RECOMMENDED (SHOULD) rather than a conditional REQUIRED, as the object has no field in which a seller claims app-ads.txt authorisation. Refs IABTechLab#15
A proposal can say its line items must be bought together (linked_execution, § 4.1), and a line item can name the line items or spend that must be in the same commitment (requires, § 5.6.3). A bonus line is a line item with requires and its own price. The § 2 "binding terms" hook now points at a field, and the Summary Representation carries has_requires and linked_execution. Adds a CTV bonus line example (§ 6.5) and linked_execution: none to the proposal example. Refs IABTechLab#23
The seller declares which exclusion types it accepts and how it
enforces each (exclusions_accepted); the buyer supplies its lists
(exclusions). Blocked apps carry their store, { platform, bundle },
so one store id is never applied across stores. Exclusions are
recompute inputs (§ 3.3) and are never disclosed to other parties
(§ 5.8). The display example declares and supplies lists.
Refs IABTechLab#25
A line item whose rate differs by market can declare geo with the selectable structure of § 3.1: available[], included[], pricing deltas and max_select. A geo that declares only allowed[] stays settable, so existing payloads are unchanged. When several priced markets are selected, the highest delta applies. The audio example is priced by market. Refs IABTechLab#14
A commitment names the proposal and version it was priced against (§ 5.6.1). The seller rejects a new attempt on a stale version, or past valid_until or price_valid_until, and returns the current version. An authenticated replay with the same idempotency_key and terms returns the stored result without re-running those checks; the same key with different terms is a conflict. Keys are opaque and scoped to one buyer and seller pair. § 4.1 states that each revision while published increments version. The display, CTV and audio examples carry proposal_id and version. Refs IABTechLab#24
§ 4.1 adds an optional, immutable proposal_template_id linking an issued proposal to the seller's template. Each issued proposal has its own status, version and negotiation_history[], and buyers never need the template id to transact. § 7 adds a non-normative note separating seller-side templates from the issued proposals buyers commit against. Appendix A gains one row; Appendix B counts immutable 6 → 7 and 72 fields. The proposal example carries a proposal_template_id. Refs IABTechLab#26
§ 5.8 adds terms_ref ({ url, sha256, version }), REQUIRED when
terms_acceptance_required is true, hash-pinned and frozen at agreed, so
assent binds to an exact document. § 5.10 adds agreement_ref, an
informative pointer to the master or annual agreement a line item is
priced under, and documents the io and agreement roles on
external_references[]. IO generation is stated to be a connector
concern, and § 7 adds a non-normative note on relationships.
agreement_ref is seller-set; a buyer-held agreement id travels as an
external_references[] entry with role: agreement, so the field keeps
one marker (§ 3).
Appendix A gains two rows; Appendix B counts seller-set 29 → 31 and
73 fields. The display example carries terms_ref.
Refs IABTechLab#27
A new § 2.3 lets a seller publish its public standard line items at /.well-known/openproposal.json: seller_id, generated_at, spec_version and, per proposal, proposal_id, version, the Summary Representation of each line item and a full_url. ETag / Last-Modified are required, only line items with visibility public appear, and entries must match the current version. Buyers discover from the manifest, then fetch the Full Representation of shortlisted line items. Adds examples/manifest.json (§ 6.5) and visibility: public to the CTV and audio examples; the registry_gated display line item is not listed. Refs IABTechLab#29
The specification does not define authentication yet (WS1; see IABTechLab#62), so the replay rule now applies to a replay from the same buyer rather than an authenticated replay. Refs IABTechLab#24
agreement_ref.parties used buyer_id, which the specification does not define. parties[] now names the seller by its seller_id and the buyer by the id it holds in eligible_bidders[] (section 5.8). Refs IABTechLab#27
The rule that a hold on a linked_execution: all proposal uses hold_scope: proposal came from a comment on IABTechLab#23, not the change request as filed. It moves to the PR description as a point for the working group, so this PR carries only the filed change. Refs IABTechLab#23
IABTechLab#25 names the content-category list iab_content_category[], a list of IAB Content Taxonomy ids. The earlier commit renamed it content_category with a version-pinned taxonomy_ref, which nobody proposed. This restores the filed name and shape; which taxonomy version to reference is left to the working group. Refs IABTechLab#25
IABTechLab#14 doesn't say how deltas combine when a buyer selects more than one priced market, and neither did any comment on it. The earlier commit said the highest delta applies; that is a design choice nobody proposed, so it moves to the PR description as a question. Refs IABTechLab#14
Read the media condition from the ad served when an impression accepts several media, name the seller as the party that serves, place linear TV outside the table, and state environments as (distribution channel, device type) pairs. Insert environments.available[] into the summary list without rewrapping it, shorten the changelog entry and drop audio_streaming from OQ-7 in docs/open-questions.md. Refs IABTechLab#90
Move the summary rule out of the § 2.1 key list, drop skip from the CTV example, and mark the CHANGELOG entry as breaking.
time_zone is the line item's clock for daypart windows and
frequency_cap.period: an IANA time zone name or viewer_local. A window
is { days[], start, end } in civil time with an exclusive end later
than start, up to 24:00; a window that crosses midnight is two windows.
List the `days[]` values once in the `daypart` row, as `monday` | ... | `sunday`. Write HH:MM, America/New_York, and UTC as plain text, since they're a format and examples, not field names. The meaning is unchanged.
"At least one of" an empty list is never satisfied, so the bonus line would fail a literal check. An absent key sets no condition. Only the examples change; the any_of[] row and the rules stay as filed in IABTechLab#23. Refs IABTechLab#23
The floor row now says it "neither constrains nor describes the downstream auction floor", as IABTechLab#16 asked, and names that floor: the per-impression floor the exchange applies at auction time (OpenRTB 2.6 Imp.bidfloor). Refs IABTechLab#16
- Rename apps[].domain to developer_domain, as IABTechLab#15 filed it. It is the developer domain from the store listing that app-ads.txt uses, not OpenRTB 2.6 app.domain, which is the domain of the app. - Define platform as the store that issued bundle, since a bundle is unique only within its store. - List apps[].platform and apps[].bundle in the Summary Representation (section 2.1), as IABTechLab#15 asked. Refs IABTechLab#15
Write the line items of examples/proposal.yaml inline, and say in section 6.1 which line item examples are extracts of it and which show a buyer's composed record. Its description and specifications now name the video and audio it sells, and the manifest is regenerated. scripts/check_examples.py checks that each line item file with no commitment equals its entry in proposal.yaml, and that proposal.yaml carries no buyer state. It builds the manifest from those line items, and the finding it held as known is gone. The display line item no longer holds the buyer's seats, which a shared proposal can't carry, and its materials are due one day before start. In proposal-issued.yaml, visibility and eligible_buyers move below the buyer's writes, which leaves its record_digest as it was.
Rename specs to format_specs and specifications to media_kit_detail. Map each format id to a FormatSpec that holds the whole spec and, for a registry entry, an EntryRef spec_ref that names one exact version. Make approval and creative_policy prose fields of section 5.4. Let a spec state what the buyer supplies, as an open vocabulary, and check that term in the examples. State in section 8 and the open questions that the draft names no way to fetch a registry entry. Give every example a whole spec for each offered format, and check format ids against the channel. Closes IABTechLab#87 Refs IABTechLab#5, IABTechLab#32
Give an asset an optional provenance record: whether its content is synthetic, what generated it, the voice consent, how it is marked or disclosed, and a digest of its bytes. The record states what the party that delivers the asset says, and is not itself a marking or disclosure. Show voice and pronunciation_guide in the host-read example, as keys the seller states in its spec. Refs IABTechLab#5
Add built_by to an asset, so assets[] can hold a seller-built read and its provenance. The seller writes the supplied keys of such an entry, and adding one needs no new version. A live read has no file to record, so it has no entry. Refs IABTechLab#5, IABTechLab#32

Make commitment.advertisers[] REQUIRED, so a commitment says whom the spend is for. Make ground REQUIRED on a decline entry. Require an answer to a commit under a firm entry while the entry holds, so that silence can't work as a decline on no ground. Refs IABTechLab#65, IABTechLab#126, IABTechLab#153
State that held means reserved inventory. Keep a hold live while a commit made during it is open, so a seller can't leave the commit unanswered until the hold lapses and then decline it for lack of availability. Add the seller's hold reference and renewal_right, an offered term for the right to the next cycle. Refs IABTechLab#66
Add seller_domain to a VersionRef outside its proposal, because a proposal_id is unique only within a seller's domain. Let a Deals API push carry the baseline in ext.baseline, so a DSP can join the deal to its record. Refs IABTechLab#31, IABTechLab#132
State the sign of agreed_rate and have the checker flag a spend commitment with no rate. Let a counter of list_rate also change included[], for a counter on a composed rate. Add location to separation, and have a demographic term state how it treats co-viewers and unknown age. Correct the discussion document's unit wording. Refs IABTechLab#38, IABTechLab#98, IABTechLab#117
A commitment now names whom the spend is for.

@KonstantinMirin thanks, I read the seller-built entries in 5160e65. That settles where provenance lives for a recorded read. One gap left: nothing says what a receiver does when a seller-built asset states |

Thanks, @cdorsey88. Agreed, and this PR adds it. § 5.4 defines We stopped short of a duty to report the mismatch, because the draft gives the buyer no channel to report on a seller-built asset. That's the gap in question 5 of the PR description. The key list marks Analyzed and generated with the help of Claude, fully reviewed by me. |

What this changes
Draft 1 doesn't say whether
specsholds a format's spec or only points at a registry entry, and a format id carries no version. A registry edit could change what an agreed line item requires. Nor can a line item say what the buyer supplies, who built an asset, or how it was made. This PR pins each spec in the record to one version and adds those three.specsbecomesformat_specs, a map fromFormatIdtoFormatSpec. AFormatSpecholds the wholespec, and aspec_refwhen the spec comes from a registry.spec_refis anEntryRef(§ 2.2), so it names one exact version. A pinnedspecequals that version's content, and the format id SHOULD match its<collection>/<entry_id>.draft, every offered format has an entry.FormatIdstarts with the line item'schannel.specMAY stateasset, what the buyer supplies, andvoice.
