…hemas Ports #8866's named rejections to 3.2.x for every node that exists there: where closure was the only thing rejecting a specific field the protocol defines elsewhere or forbids, the opened schema rejects it by name in `not`, next to additionalProperties: true. 31 of #8866's 51 named rejections apply on 3.2.x; the rest target schemas or nodes that 3.2.x does not have. Also ports #8866's description cleanups: opened schemas no longer say they are closed, and the metric-qualifier descriptions say new keys ship in a major release. The 3.3-only boolean-demographics deprecation and gender-targeting wording are not ported. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Ports #8866's test edits for the test files 3.2.x has: generic unknown-key assertions now expect the key to validate, citing DR-0009 (DR-0036 is not on 3.2.x), and the training agent test shows an unknown hard overlay requirement still matches no product.

Ports #8866's 9bda16d and 32768d4 to 3.2.x. Opening exposed anyOf unions whose branches were told apart only by which keys are present; each branch now rejects its sibling's keys by name: geo-region requirement and support countries (all_values vs values), the canonical account ref (account_id vs brand + operator), the deprecated fused-system postal area (no country), and sync_reporting_receipts results (receipt vs adjustment_receipt). Also names `step` on frequency cap impression constraints and `mode` on list-application receipts. Tests: adds canonical-account-ref.test.cjs (loading source schemas, as 3.2.x tests do), strips the format-key prohibitions from the MCP legacy-graph check, and flips the generic unknown-key vectors, citing DR-0009. PARITY_COMPILE_LIMIT is unchanged on 3.2.x; it does not trip. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…finitions on 3.2.x Ports the tools/list and parity-test parts of 9c1c52d (#8866): bundled definitions in the product-discovery tools/list schemas omit `additionalProperties: true`, which is JSON Schema's default and carries no information. The root keeps the keyword. The parity test compares openness rather than the literal keyword. The sync_principal part of 9c1c52d does not apply: the 3.2 training agent does not implement sync_principal. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

… closure (#3678) * fix(codegen): follow source additionalProperties instead of asserting closure AdCP 3.x opens the schemas that were closed by accident (adcontextprotocol/adcp#8866). The Zod generator required `additionalProperties: false` on four get_reporting_status structures and hard-coded `.strict()` or unknown-key rejection in several other post-processors, so it either failed or stayed stricter than the source. Read closure from the synced source cache everywhere a post-processor restores strictness. Still-closed sources keep their strict output, and the generated output for the current 3.3.0-beta.5 bundle is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(codegen): close only the Trusted Match request exports, not their neighbours The privacy-boundary pass rewrote everything from ContextMatchRequestSchema to OfferPriceSchema, which also closed TargetingKvsSchema, a context-match response shape. It matched the source only while targeting_kvs items were closed; adcontextprotocol/adcp#8866 opens them. Close just the request export, and give TargetingKvsSchema its own source-driven policy. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(codegen): cover source-driven closure in the Zod post-processors Inject inline source fixtures through the readSource parameters so the tests never depend on schemas/cache/latest. For each changed post-processor cover the closed source (previous strict output), the open source (no unknown-key check, no throw, runtime accept/reject of emitted Zod), and the new failure modes: title mismatch, closed root with open inline object, changed closed key sets, and targeting_kvs disagreement. Also assert the privacy-boundary pass closes only the request export. Update the three tests that hard-coded the old assertion or read the cache. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> * test(codegen): run the source-closure tests in the slow lane The file spawns a tsx harness per post-processor and runs about 25s alone, close to the fast lane's 60s file limit on a cold shard.

Ladon verdict: Escalate to human review
Escalate — gated schema paths require human/CODEOWNERS sign-off, and this PR decides a protocol-policy question.
The reviewer found no code defects. The change mechanically opens additionalProperties: false→true at 744 of 859 locations under static/schemas/source/**, keeps 115 closed for structural reasons, and adds not:{anyOf:[{required}]} named rejections where closure previously rejected a protocol-defined field. The reviewer judged the openings disjointness-safe (unchanged oneOf baseline, discriminated unions), the lint rewrite sound, the runtime adaptation in training-agent/principal.ts safe (DECLARATION_AXES matches the schema's three members), docs coherent, and the minor changeset correct for additive opening. No critical/high/medium findings were filed.
However, two hard gates apply:
-
Gated paths (decision row 2).
gated_paths: true— hundreds ofstatic/schemas/source/**files are modified — andreview_decisionisREVIEW_REQUIRED, notAPPROVED. Per the hard approval gate, this PR must not be approved without a real human/CODEOWNERS approval. -
Prose gate — protocol-policy decision / precedent reversal. The reviewer explicitly flags that this PR reverses the DR-0036 precedent (the schema-closure ratchet) and leaves that reversal plus the gated schema sign-off "to the arbiter." A PR that reverses a governance decision record is a protocol-policy act requiring human ratification, not an auto-approvable mechanical change. Combined with the un-approved review status, escalation is required.
No blocking code findings exist, so this is not request-changes; it is an escalation for required human/CODEOWNERS review and governance ratification.
Why human review
- Gated paths: this PR modifies hundreds of files under static/schemas/source/** (a hard, path-based approval gate) and review_decision is REVIEW_REQUIRED, not APPROVED — human/CODEOWNERS approval is required before merge.
- Governance precedent reversal: the change reverses the DR-0036 schema-closure ratchet, a protocol-policy decision that requires explicit human ratification on the thread rather than auto-approval.
- Protocol surface change at scale: opening additionalProperties false→true across 744 locations is a normative wire-shape decision the reviewer deliberately left to the arbiter for human sign-off.
- This PR touches a path under a hard, non-overridable approval gate (static/schemas/source/aao/agent-publishers.json (modified) matches
static/schemas/source/**; static/schemas/source/account/sync-governance-request.json (modified) matchesstatic/schemas/source/**; static/schemas/source/account/sync-governance-response.json (modified) matchesstatic/schemas/source/**; static/schemas/source/brand.json (modified) matchesstatic/schemas/source/**; static/schemas/source/collection/base-collection-source.json (modified) matchesstatic/schemas/source/**; static/schemas/source/collection/collection-list-changed-webhook.json (modified) matchesstatic/schemas/source/**; static/schemas/source/collection/collection-list-filters.json (modified) matchesstatic/schemas/source/**; static/schemas/source/collection/collection-list.json (modified) matchesstatic/schemas/source/**; static/schemas/source/collection/get-collection-list-request.json (modified) matchesstatic/schemas/source/**; static/schemas/source/collection/get-collection-list-response.json (modified) matchesstatic/schemas/source/**; static/schemas/source/compliance/comply-test-controller-request.json (modified) matchesstatic/schemas/source/**; static/schemas/source/compliance/comply-test-controller-response.json (modified) matchesstatic/schemas/source/**; static/schemas/source/content-standards/get-media-buy-artifacts-request.json (modified) matchesstatic/schemas/source/**; static/schemas/source/core/account-change-recorded-webhook.json (modified) matchesstatic/schemas/source/**; st

@KonstantinMirin, could you review and approve this as code owner? This is the 3.3 half of the Nov 9 decision to open the schemas that were closed by accident. It builds on your #8772, so you're the right second reader. The account it was opened under can't count as its own code-owner approval. What to look at:
All checks are green, including every storyboard tenant and "Generate TypeScript SDK" against SDK |

Hi Brian, thank you for this, and for folding #8772 in. I went through the four areas you listed at 96d51c9aa6. Opening 744 locations and keeping 115 is the right shape, and most of the kept-closed classes hold up. I found four things I'd like fixed before I approve, and a handful of smaller ones. Each was checked against the head, the payload cases with ajv at head and at the merge base 0f337b4ede.
Before merge
1. Two oneOf unions lost their key-presence guards. The PR adds guards to canonical-account-ref.json, but two unions of the same kind were opened without them:
core/account-ref.json:17and:52.{account_id, brand}and{account_id, operator}now validate through theaccount_idbranch. At the base both were rejected, andcanonical-account-ref.jsonstill rejects them, so the two account-reference schemas now disagree on the same payload. Suggested fix, the same ascanonical-account-ref: on branch 0"not": { "anyOf": [{ "required": ["brand"] }, { "required": ["operator"] }] }, on branch 1"not": { "required": ["account_id"] }, plus a copy oftests/canonical-account-ref.test.cjsfor it.core/requirements/image-asset-requirements.json:77and:87(bleed).{uniform: 2, top: 1}now validates under the uniform branch, so a reader that checkstopfirst computes a different bleed than one that checksuniformfirst. Suggested fix:"not": { "anyOf": [{ "required": ["top"] }, { "required": ["right"] }, { "required": ["bottom"] }, { "required": ["left"] }] }on the uniform branch and"not": { "required": ["uniform"] }on the per-side branch.
The test plan says the inventory checked every oneOf and anyOf for branches told apart only by key presence, so it may be worth re-running it with these two cases in mind.
2. Twelve named rejections forbid names the protocol never defines. The description's rule is to name a rejection where closure rejected "a specific field the protocol defines elsewhere, or one its text forbids there". These don't meet it: step (frequency-cap-impression-constraints.json:34), access_token (reporting-delivery-ready-webhook.json:109), covered (reporting-subscription-coverage.json:145, reporting-subscription-state.json:115), gpc_honored (signal-definition.json:455), political (acceptance-context.json:56), threshold_rate and per_ad_spend (outcome-target.json:81), verified (get-adcp-capabilities-response.json:926, :934), and mode on inventory-list-application.json:85, :151. No schema defines the first eight names. mode is defined elsewhere, but only in unrelated schemas, and its only justification is "matching the 3.2.10 backport". Most trace back to tests that used them as arbitrary unknown-key probes while the node was closed, for example targeting-aware-discovery.test.cjs:272-275 and reporting-status-contract.test.cjs:1762. threshold_rate and per_ad_spend are "Deferred past 3.3" (outcome-target.test.cjs:224), so 3.3 would forbid names reserved for a later minor. You already handled the same situation in d10497f081 by flipping the probes to expect acceptance (entries_total, bucket_completness, response_due_at). I'd do the same here and drop these clauses, mirrored in #8864 for the nodes 3.2.x shares. If access_token is meant as a security clamp, I'd say so in its description.
3. Most named rejections don't say why. None of the 63 new not clauses has a $comment, and for about 31 of the rejected names the name appears nowhere in the file's descriptions, for example unit (html-asset.json:68), format_ids (canonical-placement.json:143), review_sla (product-allowed-action.json:56), max_bid (outcome-target-cost-per.json:25) and context_id/status/acknowledged_at (report-media-buy-issue-request.json:93). #8531's canonical-product precedent names the absent fields in its description. Generated types can't express not, and the changeset says they now treat these objects as open, so the description is the only place a consumer learns that the field is rejected. One sentence per node, or per union, would do.
4. The "Signed commercial terms" reason isn't true as written. terms_digest is the JCS digest of the whole commercial_terms value (core/canonical-proposal.json:100). Within it, 21 object roots are open at both base and head (core/targeting.json, core/frequency-cap.json, core/ext.json, core/context.json, core/format-option-ref.json, the price guidance and breakdown schemas), and this PR opens 40 more nodes inside the same digest (brand-key, business-entity, canonical-optimization-goal, six targeting children, and others). product-purchase.json stays closed while carrying ext and context. So keeping the 25 closed doesn't prevent what the docs say it prevents: "terms_digest signs exactly those terms. If the object were open, a 3.2 buyer could accept a 3.3 term it silently ignored" (3-2-to-3-3.mdx:78, also :391, release-notes.mdx:187, whats-new-in-3-3.mdx:324, 3-3-beta.mdx:169, v4-compatibility.mdx:143, and the two changesets). The disjointness and JWS-envelope reasons don't apply either. In the envelope an extra member would sit outside the signature; here every member is inside it.
I've put the rule that does protect a buyer in #8884: the digest covers every member at every depth, including ext; accepting binds you to all of them; a party that can't interpret one refuses with UNRECOGNIZED_TERMS. It opens and closes nothing, so the two PRs agree on schema state, and I'm happy for the 25 to stay closed for the RC. I'd only ask to drop those two sentences, or call the 25 a hold until 4.0 rather than a structural reason. git merge-tree shows #8884 and this PR conflicting in exactly those three docs pages, and I'll rebase #8884 on whichever lands first.
Smaller points
- Privacy boundary, over-applied.
get-principal-response.jsonresult/oneOf/0(current) andsync-principal-response.jsonresult/oneOf/0,/oneOf/1return the caller's own configuration and are dispatched by akindconst. The oracle argument fitsrecognized,unconfiguredandfailed, not these. I'd open them or state a reason that fits. - Reporting-status clamp. The description says the
lookup_unavailablenodes' descriptions anderror-handling.mdxstate the clamp, butget-reporting-status-response.json:159-167has empty descriptions and no docs page mentions it. The invariance comes from theconstvalues. One description sentence would fix it. - Labels. "Hard constraint (must-understand)" (
proposal-budget-constraint.json) makes the same argument as the signed-terms class. I'd label both the same way. - Baseline.
metric_id(canonical-performance-standard.json) andclock/business_calendar_id(sla-window.json) are still additions to schemas that stay closed, against the guide's own line 401. If #8762 and #8501 entry 6 don't land before the RC, 3.3 ships them. Worth carrying on the RC checklist. canonical-account-refpartial guard. Theaccount_idbranch namesbrandandoperatorbut notoperator_unit,currency,timezoneorsandbox.{account_id, sandbox: true}now validates where the base rejected it. Either extend the guard or say in the description that those keys are ignored besideaccount_id.- Failed receipt branch.
sync-reporting-receipts-response.json:82-90: the four other result branches exclude the sibling receipt key, and thefailedbranch doesn't, so{result: failed, ..., receipt: {...}}now validates, while the description still says failed results expose no resource metadata. Anotfor symmetry, or drop that claim. - Lint hint.
scripts/lint-additive-minor.cjs:1355-1359still tells a developer to "record it as a correction in DR-0036 and scripts/lint-additive-minor-corrections.json", a correction kind the loader now rejects (line ~906). #8777 had reworded this line, and the port didn't carry it. - Projection test.
tests/mcp-schema-projection.test.cjs:60strips the new prohibitions by exact serialized string. Skippingnotsubtrees structurally would survive reformatting and the next named rejection. - Backport sentence. "3.2.10 opens the same locations that 3.2 has" (
.changeset/open-schemas-meant-to-be-open.md:24,3-2-to-3-3.mdx:87) is off by one node: #8864 keepsget-reporting-status-response.json#/oneOf/1/oneOf/0closed. - Baseline base.
scripts/lint-additive-minor-baseline.json:3says 3.2.8, while main now carries 3.2.9. A--prune-baselineafter the next rebase fixes it; the lint result doesn't change (4 recorded, 0 new). - Lost from #8772's docs. The fold-in carried every schema change, test and the registry entry, but two doc hunks didn't come across. In
3-2-to-3-3.mdx, the summary bullet at line 22 and the Deprecations list at line 805 don't mention the boolean form ofdemographics, although this PR deprecates it with a sender MUST. Inv4-compatibility.mdx:233, the count ofx-removed-in: "4.0.0"fields didn't move by two, and "booleandemographicsin product support" is missing from the seller-emitted list. Both hunks are in #8772 and can be copied as they are. - Closed-schema leftovers.
get_products.mdx:493andexperimental-status.mdx:155still saytarget_audiencessits besideaudience_evidence_requirementsbecause "the requirements object is a closed schema and a minor release never changes a closed schema". This PR openscore/audience-evidence-requirements.json. The sibling placement can stand on its own reason: one constrains which audience, the other the quality of the evidence. - Three copies of
range.signal-listing.json#/properties/range,get-signals-response.json#/properties/signals/items/properties/rangeandwholesale-feed-event.json#/$defs/signal/properties/rangeare the same object (min,max, both required), differing only in description, insideallOfchildren that already referencesignal-listing. Since this PR edits all three, it may be the moment to define it once ascore/signal-range.json, reference it fromsignal-listing, and drop the two copies. It validates identically, so it's safe in a minor. - Description. The details heading says "All 116 kept-closed locations" over 115 rows. The named-rejection table also misses the
fdabc7f987guards (canonical-account-ref,geo-region-requirementandgeo-region-supportcountries,postal-area,sync-reporting-receipts-response,step) andmodeoninventory-list-application, which #8864's description does list.
Happy to help with any of these, or to push the guard fixes to the branch if that's easier for you.

Bring the release notes, What's new, the 3.2 to 3.3 migration guide, the prerelease program page, Versions, and the 3.3 rows of Choose your SDK to the first release candidate. The prerelease page keeps its 3-3-beta URL and is retitled, as the 3.2 page was at its RC. rc.0 joins the checkpoint and wire-pin tables with the 3.3-rc documentation selector. Cover the 2026-11-09 decision to open the schemas that were closed by accident, and the #8501 triage that followed it: which beta fields stay in 3.3, which leave because they sit on deprecated tasks or would change a signed term, and which move. The migration guide lists every field; the other pages summarize it. Record boolean overlay demographics as deprecated. Leave the lines that #8866 rewrites alone, and fix the "closed schemas stay closed" wording it does not touch: the Send-only-to-3.3-peers intro and proposal-flow correction in the 3.2 to 3.3 guide, the 3.1 to 3.2 guide, optimization reporting, and the daily-budget spec. Describe deprecated 3.3 features as expected to be removed in 4.0, with 3.3 supported for a window after 4.0 GA, instead of the six-month notice promise. Record @adcp/sdk 17.0.0-beta.22 and Python adcp 10.0.0b15 on beta.5, Python adcp 9.6.2 with the A2A input fix on the 3.2 line, no SDK on rc.0 yet, and no Go or Java support for 3.3. Content that depends on unmerged PRs or on the rc.0 cut carries a {/* depends on ... */} marker (HTML comment in the spec markdown) so it can be re-checked before the cut.

…ves assignments (#8501) 3.3 adds no field that exists only on a deprecated task. Withdraw from get_products: refine[].package (and package-forecast-input.json), refinement_applied[] result_product_id / resolved_start_time / resolved_end_time, filters.target_audiences, include_collections and collections, and experimental price_adjustments on pricing options (with price-adjustments.json, the mismatch error details, and the vectors). Move include_execution_readiness / execution_readiness to list_products. Withdraw landing_page_url and trackers from the deprecated sync_creatives assignments[] row; the assign operation keeps them. #8866 opened the assignments[] row and the refine[] product entry, so both now reject the withdrawn request fields by name (not: required), with a description sentence: the row rejects trackers and landing_page_url, and every refine[] scope rejects package. The schema and the training agent's INVALID_REQUEST agree. The response-side refinement_applied fields are just undefined. Updates the training agent, the execution readiness storyboard, the v4 registry (canonical_price_adjustments_required_in_4_0), the oneOf discriminator baseline, docs, and tests. #8866 already removed the additive-minor baseline rows, and the 3.3 release pages are left to #8883. counting_mechanisms is left to the create/update_media_buy PR, which removes it from the shared measurement-terms.json.

…nd update_media_buy (#8501) create_media_buy and update_media_buy are deprecated compatibility tasks, so 3.3 adds nothing to them. Six fields the 3.3 betas added to them are removed; the live tasks keep every one they also carry. - predecessor_media_buy_id, lineage_reason: off create_media_buy; stay on buy_products, accept_proposal and get_media_buys. - artifact_webhook.signing_profile: off create_media_buy; no live task has artifact_webhook, so it is signed with adcp/webhook-signing/v1. - start_requires_all_creatives_approved: off package-request, package-update and core/package.json; stays on control_media_buy and get_media_buys. - target_audiences: off package-request; with #8758 withdrawing the get_products copy, no 3.3 wire form remains. - trackers, landing_page_url: off core/creative-assignment.json; stay on sync_creatives assign, list_creatives and get_media_buys. - billing_measurement.counting_mechanisms: off core/measurement-terms.json (create, update and get_products); the canonical terms gain it in 4.0. The training agent ignores the withdrawn fields on create/update, as the versioning rules require for unknown fields, and no longer echoes them in create/update responses; get_media_buys still reads back what assign set. The 4.0 registry and the task references say where each field lives; the 3.3 release pages are left to #8883. Text that called the purchase, offer-filter or canonical measurement schemas closed now says what #8866 left: the first two are open but don't define the field, and the canonical terms are held closed with the commercial terms until 4.0.

…nd update_media_buy (#8501) create_media_buy and update_media_buy are deprecated compatibility tasks, so 3.3 adds nothing to them. Six fields the 3.3 betas added to them are removed; the live tasks keep every one they also carry. - predecessor_media_buy_id, lineage_reason: off create_media_buy; stay on buy_products, accept_proposal and get_media_buys. - artifact_webhook.signing_profile: off create_media_buy; no live task has artifact_webhook, so it is signed with adcp/webhook-signing/v1. - start_requires_all_creatives_approved: off package-request, package-update and core/package.json; stays on control_media_buy and get_media_buys. - target_audiences: off package-request; with #8758 withdrawing the get_products copy, no 3.3 wire form remains. - trackers, landing_page_url: off core/creative-assignment.json; stay on sync_creatives assign, list_creatives and get_media_buys. - billing_measurement.counting_mechanisms: off core/measurement-terms.json (create, update and get_products); the canonical terms gain it in 4.0. The training agent ignores the withdrawn fields on create/update, as the versioning rules require for unknown fields, and no longer echoes them in create/update responses; get_media_buys still reads back what assign set. The 4.0 registry and the task references say where each field lives; the 3.3 release pages are left to #8883. Text that called the purchase, offer-filter or canonical measurement schemas closed now says what #8866 left: the first two are open but don't define the field, and the canonical terms are held closed with the commercial terms until 4.0.

… creative review SLA (#8762) #8501 entries 11 and 12. core/sla-window.json is held closed with the commercial terms until 4.0 (DR-0036), and 3.3.0-beta.1 added clock and business_calendar_id to it, so a strict 3.2 validator rejected a 3.3 SLA. sla-window goes back to its 3.2.8 publication (only $id differs). The signed terms reach it through change_terms[].processing_sla, and 3.2.8 says sellers include weekends and non-working periods in the maximum. clock and business_calendar_id move to core/creative-review-sla.json, which no longer composes sla-window: it defines its own durations, keeps completion_max required and the business-clock calendar rule, and is open. escalation-sla loses clock. An action's sla, a change term's processing_sla and the escalation SLA are elapsed time only. Tests pin sla-window to 3.2.8 and check the business clock is rejected on the four action schemas, the change term and the escalation SLA. The two sla-window baseline rows go, leaving 2. The MCP parity bound moves to 1_388_000 (measured 1_387_457 on main after #8866). Docs, the migration guide and a minor changeset name where the fields live now.

…porting capabilities (#8501) (#8957) The experimental available_installment_statuses (media_buy.installment_lifecycle, #8116) was defined only on core/reporting-capabilities.json, which only the deprecated get_products product uses, and 3.3 adds no field that exists only on a deprecated task. It moves unchanged to core/canonical-reporting-capabilities.json, beside supports_installment_breakdown, on the canonical product that list_products, request_proposals and refine_proposals return. #8866 opened that block (DR-0036), so the move can land in 3.3. Same items, uniqueItems, description, x-status: experimental and x-added-in: 3.3.0. The installment lifecycle docs, the get_media_buy_delivery reference and the experimental status row say where it lives, the docs example validates against the canonical schema, and the test checks the declaration there and its absence from the legacy schema. Minor changeset. Konstantin Mirin handed this move over on #8501. Refs #8501 Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

Updates the training agent, the execution readiness storyboard, the v4 registry (canonical_price_adjustments_required_in_4_0), the oneOf discriminator baseline, docs, and tests. #8866 already removed the additive-minor baseline rows, and the 3.3 release pages are left to #8883. counting_mechanisms is left to the create/update_media_buy PR, which removes it from the shared measurement-terms.json.

…lease docs After rebasing onto main with #8866 merged: - Take #8866's wording for the boolean form of demographics in the migration guide's Deprecations section, and align the release notes and What's new with it (#8778 tracks the 4.0 removal). - 3.2.10 shipped without the schema opening, so say "the next 3.2.x patch (#8864)" and "3.2.10 and earlier", including in #8866's Schemas-are-open-by-default bullet. - Drop the dependency markers #8866 satisfied, and retarget the rest. - Cover the other changes merged for rc.0: origin-only authorized_agents URLs (#8939), declared-option creative conformance (#8941), TMP cache isolation (#7446), creative.supports_registry_policy_enforcement (#8857), 3gp/mpeg/m4v containers (#8668), carousel card_image_sizes (#8937), and the loosened URL patterns (#8792). - Refresh the in-review table against the 3.3.0 milestone on 2026-11-12, and remove the stray duplicate table header it carried.

Summary
On 2026-11-09 the working group decided that 3.x opens the schemas that were meant to be open. Closing a schema only breaks validators that hard-code it, so opening one is not a protocol break. This PR makes that change for 3.3 on
main. The next 3.2.x patch (#8864) backports it from the same inventory; 3.2.10 shipped without it.additionalPropertiesgoes fromfalsetotrueat each one, and nothing else in those schemas changes. Every payload that was valid stays valid.proposal-budget-constraintare held closed until 4.0, as a hold rather than a structural reason. Brian approved the list, and three more branches opened after review. The reasons and the full list are below.not: { anyOf: [{ required: [...] }] }. This follows fix(schemas): reopen the 3.2 proposal-flow schemas closed against DR-0019 #8531's precedent oncanonical-product, so those payloads are still rejected.demographicsdeprecation, its tests and docs. fix(schemas): open the capability blocks and containers 3.3 extends, against DR-0019 (#8501) #8772 is superseded.

rejections in opened schemas
Each node opens and keeps rejecting the named fields in
not: { anyOf: [{ required: [...] }] }, and its description (or its union's) says what it rejects and why, because generated types can't expressnot. A rejection names only a field the protocol defines elsewhere or forbids there; probes for names defined nowhere now expect acceptance. The key-presence guards (account-ref,canonical-account-ref, imagebleed, geo-region requirement and supportcountries,postal-area,sync-reporting-receipts-responseresults) keep union forms apart.
