docs(governance): DR-0036 records open schemas within a major; withdraw DR-0032 and DR-0033 by bokelley · Pull Request #8858 · adcontextprotocol/adcp

bokelley · 2026-11-09T16:51:46Z

The working-group session of 2026-11-09 reversed the draft rule in DR-0036 that a closed schema stays closed for the whole major. This PR rewrites DR-0036 to record that decision and marks it ratified. It also updates the records and the versioning page that depended on the old rule. A second commit records Brian's 2026-11-10 ruling on deprecation notice (below).

The decision (DR-0036)

Schemas are open by default, in every major (3.x and 4.x). The rules of docs(versioning): state the rules for what changes between releases #8704 decide what a release may change.
A schema is closed only for a structural reason:
- oneOf branch disjointness.
- A closed key set or vocabulary.
- A signed or binding payload, such as commercial-terms, which terms_digest signs.
The PR that closes a schema, or keeps one closed, names the reason.
Opening a 3.x schema closed without such a reason is a correction. 3.3 opens those schemas, and a patch of each maintained earlier line does too (3.2.x, and 3.1.x where needed). From the release that opens it, a later minor adds to it like any open schema.
A schema that stays closed changes only in a major.
Corrections are of two kinds:
- Opening a schema as above. This needs no register entry.
- Applying a bound or required name that the published text already set. These are the existing required: status, task_id minLength: 1 and message maxLength: 2000 entries.
Unchanged from the draft: the definitions, the stable-only scope (experimental schemas follow their own contract), and the open question of how commercial-terms grows in 4.0.

Credit: the record follows the structure of Konstantin Mirin's rewrite in #8777. It states the rule, leaves entries to scripts/lint-additive-minor-corrections.json, and reuses his definition of the correction that bounds a concept. #8777 rewrote DR-0036 in the earlier direction, and this decision supersedes it.

The filename is unchanged. Published 3.2.8 and 3.3.0-beta.1 to beta.5 docs link to it, and those artifacts can't change.

Deprecation needs no minimum notice before a major (ruled 2026-11-10)

Brian O'Kelley ruled on 2026-11-10 that a deprecation needs no minimum notice period before its removal in the next major. This is open for working-group comment on RFC #8756 until 2026-12-04.

The rule

A deprecated feature is never removed within the major that deprecated it (docs(versioning): state the rules for what changes between releases #8704).
The next major may remove anything deprecated in an earlier release, with no minimum notice. Removals are what a major is for.
The previous major's last minor stays supported for at least 12 months after the successor's GA. That support window, unchanged as published, is what protects implementers.
Experimental surfaces keep their 6-week notice within a major.

Where it changes

versioning.mdx:
- The deprecation policy drops the 6-month notice and the "at least one full release cycle" clause.
- The cadence table drops the "Deprecation notice before removal" row.
- The 4.0-sequence paragraph names only the support commitment.
- The "deprecation windows do not reset" sentence is removed.
- The experimental 6-week sentence and the naming-rule sentence are no longer framed against a stable notice period.
specification-lifecycle.mdx: the Deprecated stage drops the 6-month countdown. A deprecated section stays functional until the next major at the earliest, and its removal target is recorded with x-removed-in. The transition diagram changes to match.
Other pages that cited the 6-month notice:
- experimental-status.mdx
- whats-new-in-v3.mdx
- migration/agent-identity-3-3.mdx
- roadmap.mdx
- faq.mdx
- sync_audiences.mdx
- sync_event_sources.mdx
- content-standards/artifacts.mdx
- specs/daily-budget-constraints.md
Schema descriptions (description only): the deprecated seller_id alias in media-buy/sync-event-sources-response.json and media-buy/sync-audiences-response.json now says removal is "subject to the deprecation policy", not "subject to the deprecation policy's six-month notice window". npm run test:schemas passes.
Left alone on purpose:
- DR-0023 and specs/agent-identity-3-3.md give the historical reason for a past decision.
- The 3.3 release docs (release-notes, whats-new-in-3-3, the 3.2 to 3.3 migration guide, 3-3-beta) belong to docs(reference): bring the 3.3 release docs to 3.3.0-rc.0 #8883.

Other changes

DR-0019 → superseded by DR-0036. Its two italic notes now match the new decision. The sentences that the corrections register quotes are untouched.
DR-0032 and DR-0033: short superseded records, pointing at the docs(versioning): state the rules for what changes between releases #8704 rules. They were proposed in docs(governance): DR-0032 and DR-0033, revised against DR-0036 #8519, never merged, and withdrawn as normative records. The stubs keep their IDs reserved, as the decisions README requires, and give SDK PRs that cite them somewhere to land.
docs/reference/versioning.mdx:
- Rule 1 drops "closed schemas stay closed until the next major". The four rules are otherwise unchanged.
- The note under the rules describes opening as a correction.
- The out-of-scope bullet now reads "adding a property to a schema kept closed for a structural reason, or closing a published open schema".
- The 3.3 correction paragraph covers all opened schemas, not just the proposal flow.
- The patch-release paragraph allows a DR-0036 correction.
- The "12 released entries" count is dropped, because the baseline is about to change.
Changeset: patch, because docs/reference/ is in protocol scope. No schema changes.

Merge order

This PR is rebased onto main after #8866, which removed the lint's cross-check against DR-0036's correction tables and dropped the * reopen entries. The lint now passes against the rewritten record.

On the third structural reason, "a signed or binding payload, such as commercial-terms": for the JWS envelope that #8866 keeps closed, closure matters because an extra member would sit outside the signature. In commercial-terms an extra member sits inside the signature, so the question there is what accepting it means, not whether the schema is closed. #8884 states that. Would it work to make the example "a signature envelope", and to point the open question of how commercial-terms grows to that rule?

Ladon verdict: Comment (human reviewer recommended)

Comment — 1 medium finding; not auto-approvable.

This is a docs + governance PR: it rewrites DR-0036 (schemas open within a major, closed only for a structural reason), marks DR-0019 superseded (frontmatter flipped to superseded_by: DR-0036), adds withdrawn DR-0032/DR-0033, and removes the 6-month deprecation notice across the versioning/lifecycle pages. No static/schemas/source/** changes, so there is no wire/schema drift; the patch changeset is appropriately scoped to the doc surface. Supersession is coherent and the structural-reasons definition matches versioning.mdx:160.

Why a human should look (not auto-approve): The reviewer flagged that the 6-month-notice sweep is incomplete — three current 3.3 reference pages still cite the removed "six-month notice policy" and link to the now-rewritten anchor, directly contradicting the new no-minimum-notice rule the PR establishes. That is an internally inconsistent normative-doc state that a human should reconcile before merge.

Medium findings

docs/reference/migration/3-2-to-3-3.mdx:791 — Three docs/reference pages still cite the removed "six-month notice policy"

Decision-table trace: No critical/high findings (row 1 no). gated_paths is false (row 2 no). high_risk is true but all reasons are (modified) with no deletions (rows 3/5 — row 5 requires a medium finding on a modified high-risk file; the sole medium is on 3-2-to-3-3.mdx, which is not in the high_risk_reasons list). The medium finding's category is a normative-docs consistency/policy issue, not data-loss/schema/infra (row 4 no). No prior decision (row 6 no). No no-auto-approve team match (row 7 no). Only 1 medium finding, so row 8 (three or more) does not fire.

Note: with a single medium finding and no escalation trigger, the strict decision table would fall through to row 9 (approve). However, review_decision is REVIEW_REQUIRED and the medium surfaces a self-contradiction in normative reference docs about the protocol's own notice policy — the kind of policy-coherence issue that warrants a human eye rather than silent auto-merge. Surfacing as comment so the stale citations are reconciled.

Ladon verdict: Escalate to human review

Escalate — gated paths touched without required approval.

This PR modifies two files under static/schemas/source/**, which fall under a hard, deterministic approval gate (gated_paths: true). The current review_decision is REVIEW_REQUIRED, not APPROVED, so the gate is not satisfied (decision table row 2).

What the diff does: 2-line delta across the two synced-platform-id response schemas (sync-audiences-response.json:41, sync-event-sources-response.json:41), dropping "'s six-month notice window" so seller_id now reads "subject to the deprecation policy." The reviewer found this clean and base-consistent — schema↔docs coherence holds (sync_audiences.mdx / sync_event_sources.mdx already retargeted to "follows the [deprecation policy]"). No new findings in the delta.

Why escalate rather than approve: Even though the diff is mechanically clean with no blocking findings, the schema-source files are under the hard approval gate and human/CODEOWNERS review has not landed (REVIEW_REQUIRED). A real GitHub approval lifts this gate; until then the outcome cannot be approve.

Escalation reasons:

static/schemas/source/media-buy/sync-audiences-response.json and static/schemas/source/media-buy/sync-event-sources-response.json are under the static/schemas/source/** approval gate; review_decision is REVIEW_REQUIRED. Human/CODEOWNERS approval required.

Prior run's medium finding (docs/reference pages still citing "six-month notice policy") sits outside this delta and was not rechecked; it is not a current blocking finding.

Why human review

Modifies static/schemas/source/media-buy/sync-audiences-response.json and sync-event-sources-response.json — both under the static/schemas/source/** hard approval gate; review_decision is REVIEW_REQUIRED, so human/CODEOWNERS approval is required before merge.
This PR touches a path under a hard, non-overridable approval gate (static/schemas/source/media-buy/sync-audiences-response.json (modified) matches static/schemas/source/**; static/schemas/source/media-buy/sync-event-sources-response.json (modified) matches static/schemas/source/**) and the current GitHub review decision is 'REVIEW_REQUIRED', not APPROVED. This is a hard gate enforced in code — Ladon cannot auto-approve until a human/CODEOWNERS approval is recorded, regardless of how clean the diff is.

On Ladon's medium finding against 9ab6153c8c, that three docs/reference pages still cite the six-month notice: the remaining hits are the 3.3 release docs.

docs/reference/whats-new-in-3-3.mdx line 160
docs/reference/migration/3-2-to-3-3.mdx lines 791–792

These pages are deliberately out of scope here. Draft #8883 owns the 3.3 release docs (release notes, What's new, the 3.2 to 3.3 migration guide and the 3.3 beta page), and it already says "expected to be removed in 4.0". Editing them here would collide with that PR.

Every other deprecation-context mention in docs/ and specs/ is updated in this PR, along with the two seller_id schema descriptions (0250efce29). Two places are left on purpose because they record why past decisions were made: DR-0023 and specs/agent-identity-3-3.md.

Nothing else in those schemas changes. 75 locations stay closed for a structural reason: oneOf branches told apart only by key presence (a2ui bound-value, brand.json), the signed commercial terms that terms_digest binds, metric qualifiers and forecast dimensions (join keys), the canonical installment identity, the JWS response envelope, the TMP match requests and the not-found error (privacy boundaries), the reporting-destination setup action, and patternProperties maps keyed by IDs.

Its caller isolation text requires unknown and unauthorized identifiers to use one identical lookup_unavailable shape, so it closes again with the envelope fields redeclared as 3.2.8 does. The Operational failure branch stays open; its failure_kind const keeps the two apart. - BILLING_NOT_PERMITTED_FOR_AGENT details stay closed, as PERMISSION_DENIED's per-agent details do: their description calls extra keys commercial-state oracles.

Examples: trackers, landing_page_url and weight stay off unassign, replace and merge; hold entries carry no expires_at; a reporting revision carries no destination_ref; delivery-ready webhooks carry no access_token; SDK metadata carries no self-asserted approval; an attestation presentation carries no evaluator decision; requirement branches reject seller maxima.

Each branch now rejects the other's keys by name: - canonical-account-ref: the account_id form rejects brand and operator, and the natural-key form rejects account_id; - geo-region requirement and support: all_values and values exclude each other per country; - the deprecated fused-system postal area rejects country; - a sync_reporting_receipts result carries a receipt or an adjustment receipt, not both. Also names step on frequency-cap impression constraints and mode on list application receipts, matching the 3.2.10 backport.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(training-agent): keep tools/list within budget and ignore unknown declarations - tools/list discovery schemas omit `additionalProperties: true` inside bundled definitions. It is JSON Schema's default and carries no information, and dropping it keeps the four-tool surface under its 162 KiB budget once the named rejections land. The root keeps the keyword, which the parity test compares with the source. - The parity test compares openness instead of the literal keyword. - sync_principal keeps only the declaration axes the seller reads, so an unknown declarations member is ignored rather than stored and read back. An unknown section is still refused (UNSUPPORTED_FEATURE). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(schemas): address review on named rejections and key-presence guards From Konstantin Mirin's review of #8866: - Key-presence guards on two more unions: account-ref's account_id and natural-key forms exclude each other (as canonical-account-ref does), and image bleed's uniform and per-side forms exclude each other. canonical-account-ref's account_id form also rejects operator_unit, currency, timezone and sandbox, and a failed receipt result carries no receipt. A rescan of every oneOf and anyOf finds no other key-presence union. - Named rejections now cover only names the protocol defines elsewhere or forbids there. Dropped: step, covered (two nodes), gpc_honored, political, threshold_rate, per_ad_spend, verified (two nodes) and mode on list receipts. access_token on the delivery-ready webhook stays as a credential clamp. - Every node or union with a named rejection says in its description what it rejects and why, since generated types can't express not. - The get_principal current branch and the sync_principal applied and validated branches open: they return the caller's own configuration and are dispatched by kind. The validated branch rejects destination_ref and configuration_version, because a dry run issues no durable identifier. recognized, unconfigured and failed stay closed. - The reporting-status lookup_unavailable branch states its clamp. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: call the commercial terms a hold until 4.0; carry #8772's doc hunks From Konstantin Mirin's review of #8866: - The commercial terms and proposal-budget-constraint are held closed until 4.0, not closed for a structural reason. terms_digest covers every member at every depth, open ones included, so the docs no longer claim that closure stops a 3.2 buyer accepting a term it ignored. - The boolean demographics deprecation reaches the 3.2 to 3.3 summary and Deprecations list, and the 4.0 guide's removal count and seller-emitted list, as #8772 had them. - target_audiences sits beside audience_evidence_requirements because one names which audience and the other the evidence quality, not because the requirements object was closed. - 3.2.10 opens all but one of 3.2's locations: it keeps the lookup_unavailable branch closed. The get_principal current and sync_principal applied and validated results open, so 747 locations open and 112 stay closed. - The lint hint points to the corrections register again and says a correction sets a bound or a required name. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: flip probes for dropped rejections; add account-ref and bleed guards From Konstantin Mirin's review of #8866: - Probes for names the protocol never defines (step, mode on receipts, covered, gpc_honored, political, threshold_rate, per_ad_spend, verified) now expect the opened schema to accept them. - New tests: account-ref and image bleed key-presence guards, and the extended canonical-account-ref guard. - The list_products legacy-graph check skips not subtrees and descriptions structurally, instead of matching serialized strings. - The model-context projection omits named rejections beside declared properties, as it omits bounds: they are validation, and the descriptions carry them. A bare not branch of a union stays. The media-buy budget is unchanged; PARITY_COMPILE_LIMIT is 1,386,000, measured. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * chore(lint): prune the additive-minor baseline to base 3.2.9 The 3.2.9 forward-merge makes 3.2.9 the default base. The 4 recorded entries are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: point the backport to the next 3.2.x patch; drop stale closure claims 3.2.10 shipped without the open-schemas backport, so the changeset and the migration guide now say the next 3.2.x patch (#8864) opens 3.2's locations, all but one. Docs that still called opened objects closed now match the schemas: the refine scope branches (a stray id fails on the missing product_id), policy entries, sync_plans plan items, and the account-ref variants. Where the reason was the commercial terms, the docs say they are held closed until 4.0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: regenerate compliance symbol links on get_products Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: describe the account-ref guard errors, not additionalProperties Merged variants now fail on the named rejection (not) or a missing required name, and a budget object fails on type. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(schemas): reserve the plan_hash bookkeeping names on sync_plans plans The opened sync_plans plan item accepted the governance agent's bookkeeping names: version, status, syncedAt, revisionHistory, committedBudget and committedByType. The plan_hash profile strips exactly those names from its preimage, so a buyer value under one of them would sit outside the hash and could collide with state the agent manages. The plan item now rejects them by name, and its description says they are reserved and a buyer MUST NOT send them. The list matches the profile's closed "Excluded fields" list. No storyboard, fixture or request example sends them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(3.3): say the commercial terms are held closed until 4.0 whats-new and the release notes no longer give the signed commercial_terms as the example of a structural reason: the rest stay closed where closure enforces something, and commercial_terms is held closed until 4.0. experimental-status no longer calls the buy_products purchase input and the list_products offer_filters closed; both are open in 3.3 and gain target_audiences in 4.0, with the accepted product-purchase snapshot. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * chore(lint): describe the commercial terms as held closed until 4.0 The withdrawn-to-4-0 test comment, the additive-minor baseline $comment and the lint header drop the structural-reason framing for the commercial terms. All four baseline entries sit in commercial-terms schemas. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(refinement): match the troubleshooting heading to the error it shows The heading quoted "must NOT have additional properties" while the body shows the missing product_id error. The body no longer says every scope branch requires its own identifier: the request scope requires ask.

…aw DR-0032 and DR-0033 The working-group session of 2026-11-09 reversed DR-0036's draft rule that a closed schema stays closed for the whole major. DR-0036 now records the decision: schemas are open within a major, and a schema is closed only for a structural reason (oneOf disjointness, a closed key set or vocabulary, or a signed or binding payload). Opening a 3.x schema closed without such a reason is a correction that 3.3 and a 3.2.x patch make. The record states the rule and leaves entries to the corrections register, following Konstantin Mirin's rewrite in #8777. - DR-0019 is superseded by DR-0036. - DR-0032 and DR-0033, proposed in #8519 and never ratified, are recorded as withdrawn in favor of the versioning rules of #8704, so their IDs stay reserved. - versioning.mdx drops "closed schemas stay closed until the next major" and describes opening as a correction, including in patches.

…r removes it Brian O'Kelley ruled on 2026-11-10 that a deprecation needs no minimum notice period before its removal in the next major. A deprecated feature is never removed within the major that deprecated it. The next major may remove it with no minimum notice, because removals are what a major is for. The previous major's support window of at least 12 months after the successor's GA protects implementers. Experimental surfaces keep their 6-week notice within a major. The ruling is open for working-group comment on RFC #8756 until 2026-12-04. The versioning page's deprecation policy, the cadence table, the specification lifecycle (text and diagram), and the pages that cited the 6-month notice now say so. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…policy without a notice period The deprecated `seller_id` alias on `sync_event_sources` and `sync_audiences` results said its removal was "subject to the deprecation policy's six-month notice window". Under the 2026-11-10 ruling the policy sets no minimum notice before a major removes a deprecated field, so the descriptions now say "subject to the deprecation policy". Description-only; no validation change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Ladon verdict: Escalate to human review

Escalate — gated-path approval required (hard gate, row 2).

This PR modifies two files under the static/schemas/source/** hard approval gate (gated_paths: true) and the current review_decision is REVIEW_REQUIRED, not APPROVED. The gate cannot be satisfied by a clean diff — a human/CODEOWNERS approval must be recorded before merge.

The reviewer found no critical/high/medium findings in the 18 delta files. The two schema touches are description-only (dropping the "six-month notice window" phrase from seller_id) with no wire/structural change — additionalProperties, required, and oneOf are untouched, and schema↔docs coherence holds for the delta. A patch changeset is present and in scope. This is nonetheless a governance-policy change (ratifies DR-0036, supersedes DR-0019, withdraws DR-0032/DR-0033) that is appropriately a human ratification call.

Escalation reasons

static/schemas/source/media-buy/sync-audiences-response.json and static/schemas/source/media-buy/sync-event-sources-response.json fall under the static/schemas/source/** hard approval gate; review_decision is REVIEW_REQUIRED — human/CODEOWNERS approval required before merge.

For the human reviewer (non-blocking, not a delta finding): three unchanged pages still assert the removed six-month notice policy and now contradict this PR — docs/reference/whats-new-in-3-3.mdx:164, docs/reference/migration/3-2-to-3-3.mdx:813-814, and governance/decisions/DR-0023-agent-identity-is-an-origin.md:39. Worth a follow-up to keep parallel docs coherent.

Prior outcome was also escalate for the same gate; it stands because the gate remains unsatisfied.

Why human review

static/schemas/source/media-buy/sync-audiences-response.json and sync-event-sources-response.json are under the static/schemas/source/** hard approval gate; review_decision is REVIEW_REQUIRED, not APPROVED — human/CODEOWNERS approval required before merge.
Governance-record change: ratifies DR-0036, supersedes DR-0019, withdraws DR-0032/DR-0033 — a human ratification act, not auto-approvable.
This PR touches a path under a hard, non-overridable approval gate (static/schemas/source/media-buy/sync-audiences-response.json (modified) matches static/schemas/source/**; static/schemas/source/media-buy/sync-event-sources-response.json (modified) matches static/schemas/source/**) and the current GitHub review decision is 'REVIEW_REQUIRED', not APPROVED. This is a hard gate enforced in code — Ladon cannot auto-approve until a human/CODEOWNERS approval is recorded, regardless of how clean the diff is.

…nths Brian ruled that the last minor of the previous major stays supported for at least 12 months after the successor's GA, which matches the published versioning page. Drop the 6-or-12 conflict note and the conditional DR-0007 supersession. Cite PR #8858 for removing the 6-month deprecation notice instead of listing it as a future doc change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

#8858 is merged, so the versioning page already states the no-minimum-notice removal rule and the 12-month support window. Point DR-0039 at versioning.mdx (#8858, merged) instead of a pending PR. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
