It MUST NOT be +treated as an accepted protocol requirement until the RFC completes the +required review period and has an accepted decision record. + +## Problem + +An advertiser account is rarely controlled by one buyer agent. A seller +operator, another authorized principal, seller automation, or a connected +platform can create and modify campaigns, creatives, budgets, account state, +and reporting without a preceding task from the observing buyer. + +AdCP has four different concepts today: + +1. authoritative reads describe current state; +2. task responses acknowledge one requested operation; +3. webhooks notify selected changes or deliver reporting data; and +4. `webhook_activity[]` records delivery attempts for debugging. + +None is a durable, ordered account-wide record of material business-state +changes. `get_media_buys.history[]` is bounded and buy-specific, task history +does not contain out-of-band changes, and webhook delivery can be missed. + +The result is a convergence gap: a buyer connecting to an existing shared +account cannot mechanically establish what is true now and what changed while +it was offline. + +## Normative invariant + +For every committed material change to account-scoped control-plane state +designated by an authoritative AdCP read, a seller supporting the account +change feed MUST: + +1. reflect the resulting current state on that authoritative read regardless + of whether the change originated through AdCP, a seller UI or API, seller + automation, another authorized principal, or a connected platform; +2. append at least one immutable account change record at the persistence + boundary described below; +3. make the authoritative snapshot and change record readable before + enqueueing a notification; and +4. fan out `account.change_recorded` to every active account subscriber that + explicitly requested that event type. + +A synchronous task response does not suppress the change notification. The +account can have other subscribers and authorized principals that did not +invoke the task. + +For a mutation mediated by the seller, the authoritative projection and its +change records commit atomically. For an externally mediated change that the +seller observes through polling, subscription, or pass-through integration, +the records commit atomically with the seller's ingestion or projection of +that observation. An authoritative pass-through read MAY expose upstream state +before the feed observes it, but only within the connected source's declared +freshness bound. The seller does not notify until the record and any +seller-maintained projection are readable. Advertising coverage therefore +requires bounded external observation; it does not require a transaction that +spans the seller and an upstream platform. + +### Minimum invalidation granularity + +A seller emits at least one record per independently repairable authoritative +identity affected by a commit. One operation that changes several independent +creatives therefore emits one record per creative. Changes to packages and +assignments MAY coalesce into one media-buy record only when `get_media_buys` +fully repairs the entire changed closure for that media buy. A seller does not +need one record per changed field. + +Records from the same operation or external ingestion batch MAY share +`batch_id`. That identifier groups records only; each record keeps its own +`change_id`, cursor position, resource identity, and logical notification. + +This is not event sourcing. Current state remains authoritative on the named +read, while a change record proves that a material transition was recorded and +points at the repair read. Deletion records are durable tombstones because the +current-state read cannot recover a deleted resource. + +### Included changes + +Material changes include resource creation or discovery, lifecycle state, +spend and delivery controls, flights, targeting, creative content and +assignment, account access and status, financial state, reporting corrections +and finality, and deletion or purge markers when those fields are part of a +covered authoritative read. + +### Excluded observations + +The following do not produce account change records: + +- reads, previews, and dry runs; +- validation failures and operations that do not commit; +- exact idempotency replays; +- no-op connector polls and timestamp-only reevaluations; +- webhook delivery attempts; +- impression-level delivery counter accumulation; +- raw audience members, raw catalog item bodies, and raw logged events; and +- internal optimization decisions that stay within an already-authorized + control envelope and do not alter a covered current-state field. + +A reporting correction, finality transition, budget-control change, or other +material revision is included even though routine counter accumulation is not. + +## Authoritative coverage matrix + +The following table is normative for sellers that advertise the corresponding +resource type in `account.change_feed.resource_types`. “Source-neutral” means +membership and state depend on caller access, never on whether AdCP created the +resource. + +| Resource family | Authoritative current-state read | 3.2 requirement | +| --- | --- | --- | +| Account identity, status, authorization, billing configuration | `list_accounts` | Complete current state; source-neutral changes recorded. | +| Account spend, credit, payment, invoices | `get_account_financials` | Complete when account financials and this resource type are advertised. | +| Media buys and packages | `get_media_buys` | Every caller-visible account buy, including external creation and modification; buyers enumerate every status and page. | +| Delivery and reporting | `get_media_buy_delivery` | Current results within declared parity; corrections, adjustment, and finality revisions recorded. Routine metric increments are excluded. | +| Creative library | `list_creatives` | Every caller-visible creative regardless origin, with current content revision or digest and lifecycle state. | +| Creative assignment and approval | `get_media_buys`; optional reverse projection on `list_creatives` | Exact current relationship and approval; changes recorded. | +| Audiences | `sync_audiences` discovery mode | Native/connected identity, management origin, and current revision are required before a seller advertises audience coverage. Raw members never enter the feed. | +| Event sources | `sync_event_sources` discovery mode | Buyer- and seller-managed sources are source-neutral and changes are recorded. | +| Catalogs | `sync_catalogs` discovery mode | Native/connected identity, management origin, and current revision are required before catalog coverage is advertised. Item bodies do not enter the feed. | +| Wholesale products and signals | `list_products` / `get_signals` | Existing versioned feeds stay authoritative. Account changes record control or bulk revisions rather than duplicating every feed entity body. | + +An implementation MUST NOT advertise a resource type whose current material +state cannot be recovered through its named read. Inline-only creative bodies, +native audience/catalog identities, and opaque mutable package fields are +known specification gaps to close before claiming coverage; the change feed +does not paper over them. + +## `list_account_changes` + +`list_account_changes` is an optional, read-only task. It is exposed only when +`account.change_feed.supported` is true. + +### Request + +The request contains one required `account` and accepts: + +- `cursor`: opaque checkpoint from a prior call; +- `starting_position`: `earliest` or `latest`, valid only without `cursor`; +- `resource_types`: optional exact filter; and +- `max_results`: 1–100, default 50. + +`earliest` is the default initial position and starts at the oldest retained +record. `latest` returns a checkpoint at the seller's current ingestion +high-water. A cursor is bound to authenticated principal, resolved account, +and normalized filter set and MUST NOT be reusable under another scope. +The completeness-first `earliest` default is intentional for callers that ask +for history without first bootstrapping; the recommended projection bootstrap +still begins at `latest`. + +### Response + +The response contains: + +- `changes[]`, ordered oldest first; +- `cursor`, always present even when `changes[]` is empty; +- `has_more`; +- `available_since`; +- `generated_at`; and +- optional account-specific `source_coverage[]` watermarks. + +This task deliberately does not use `pagination-response.json`: ordinary +pagination omits a cursor at the tail, while a tailing feed requires a durable +empty-page checkpoint. + +### Cursor rules + +Cursor order is a total account order independent of timestamps. A cursor +means strictly after its scanned high-water. Appends never reorder previously +returned pages. A filtered page advances across nonmatching records, and an +empty page advances to the current scanned high-water. + +A seller MUST reject a cursor presented with a different principal, account, +or normalized filter set using `INVALID_REQUEST` with `field: "cursor"`. It +MUST NOT apply new filters at the embedded position because doing so can +silently skip older records. The rejection does not advance a checkpoint. + +If a cursor falls outside retention, the seller MUST return +`CURSOR_EXPIRED`. It MUST NOT silently restart from the retention boundary. +The error is `correctable`; recovery is to acquire a new latest checkpoint, +rebuild authoritative snapshots, and drain from that checkpoint. + +The seller retains account changes for at least 90 days after recording. +`available_since` publishes the actual retained boundary. Sellers do not +fabricate history from before adopting the feed. + +### Race-free bootstrap + +1. Discover `account.change_feed` and the account's current source coverage. +2. Register `account.change_recorded` on `sync_accounts`. +3. Call `list_account_changes(starting_position: "latest")` and persist C0. +4. Enumerate every authoritative account snapshot, including every lifecycle + status rather than active-only defaults. +5. Drain changes after C0 and reread the resources they name. +6. On each signed notification, drain from the persisted cursor again. +7. Poll periodically so webhook loss cannot create a permanent gap. +8. On `CURSOR_EXPIRED`, repeat the bootstrap. + +Changes committed while step 4 is in progress appear after C0, closing the +multi-read bootstrap race. + +## Change record + +Every `account-change.json` record has: + +- stable `change_id`; +- seller `recorded_at` and optional trustworthy upstream `occurred_at`; +- optional `batch_id` grouping records from one commit without weakening + per-identity invalidation granularity; +- structured resource type, account, ID, and optional parent IDs; +- open `action`, with standard values `created`, `discovered`, `updated`, + `status_changed`, `linked`, `unlinked`, `deleted`, and `purged`; +- server-derived origin kind; +- an allowlisted read-only `repair.task` hint. Buyers construct and validate + arguments locally from the authenticated account and resource identity and + never dispatch feed data directly; and +- optional revision, changed JSON Pointer paths, redaction-safe actor, reason, +summary, and bounded extension metadata. + +Each encoded record is limited to 64 KiB, with at most 64 changed paths and 20 +extension namespaces. IDs, paths, summaries, reasons, actor labels, and +extensions are untrusted seller input: buyers do not interpolate them into +system prompts, execute them, or use them as authorization evidence. + +Unknown resource and action values remain processable as generic +invalidations. Change records never carry credentials, setup tokens, bank +details, raw audience members, raw logged events, webhook bodies, internal +stack traces, or unbounded before/after snapshots. + +For a deletion or compelled legal purge, the record keeps only a non-sensitive +identity, time, category, and repair disposition. If law requires removing +even that metadata, the seller documents the legal exception and MUST NOT +represent the affected interval as complete. + +## `account.change_recorded` + +The notification is account-anchored and registered through +`sync_accounts.accounts[].notification_configs[]`. Each committed change +produces one logical notification per subscribed endpoint. + +The payload carries `account_id`, `change_id`, resource identity, action, +`recorded_at`, and an optional advisory `through_cursor` target. +`notification_id` equals `change_id`. Transport retries reuse the same +`idempotency_key`; deliberate re-emission uses a new delivery key with the +same logical notification ID. + +The payload is an invalidation, not current state. A receiver MUST NOT install +`through_cursor` without reading intervening feed pages. Existing specialized +notifications remain valid and can overlap the generic change notification. + +## Connected-source coverage + +The seller-wide capability lists resource types the seller can support. +`list_account_changes.source_coverage[]` reports account-specific source +health with a source kind, status, resource types, optional coverage start, +last successful sync, and observed-through watermark. + +Every connected source that reports `current` MUST provide +`last_successful_sync_at` and `stale_after_seconds`. At response +`generated_at`, the last successful sync MUST be no older than that threshold, +and the seller must know of no ingestion gap. A source is `delayed` when the +threshold is exceeded or a gap is known, and `unavailable` when observation +cannot currently proceed. `observed_through` describes upstream business-time +coverage; it is not a substitute for the last successful poll, subscription +heartbeat, or equivalent observation time. + +`has_more: false` means the caller is caught up to seller ingestion. It does +not mean an unavailable upstream platform has been observed through the +present. A seller may report a connection as delayed or unavailable; it may +not silently omit connected resources while reporting current coverage. + +## Authorization and privacy + +Current authorization controls both snapshots and history. Sellers filter +inaccessible resource changes without revealing their existence or count, but +still advance the scoped cursor across filtered records. Cursors are bound to +the authenticated principal and an authorization-scope epoch to prevent +cross-principal reuse and gaps after a visibility change. + +Whenever the set of resources visible to that principal and account expands or +contracts, the seller changes the epoch. A cursor from the prior epoch returns +`CURSOR_EXPIRED` with `details.reason: "authorization_scope_changed"` and the +ordinary latest-checkpoint snapshot-rebootstrap guidance. The seller MUST NOT +resume it after records that were skipped under the old scope. Implementations +whose authorization is immutable full-account access may use one stable epoch +for the lifetime of that grant. + +Subscriber authorization is rechecked when each notification is fired. Losing +account access immediately suspends or removes that principal's subscriptions; +a previously accepted endpoint is not a permanent grant. + +Actor metadata is server-derived and privacy-redactable. The feed is not a +substitute for a security audit or user-activity log. `origin` and `actor` are +seller assertions, not independent provenance, and MUST NOT grant access, +establish nonrepudiation, or bypass buyer policy checks. The feed does not +include logins, failed actions, or webhook transport attempts. + +## Conformance requirements + +Capability-gated conformance MUST test: + +1. out-of-band create, update, status, relationship, correction, and deletion + appear on both the source-neutral snapshot and the change feed; +2. snapshot and change record are readable before webhook enqueue; +3. AdCP, seller-operator, seller-system, connected-platform, and + other-principal origins produce records; +4. no-op, failed, dry-run, and exact idempotency replay calls do not; +5. total ordering, timestamp ties, pagination, concurrent appends, filters, + mandatory cursor-scope mismatch rejection, empty-tail checkpoints, expiry, + authorization-epoch changes, and rebootstrap are gap-free; +6. subscriber activation, fan-out, retry and re-emission identity, and + specialized-notification overlap behave as specified; +7. cross-account and cross-principal isolation, actor redaction, and absence of + secrets and PII; and +8. retention and connected-source freshness classifications match their + advertised timestamps and `stale_after_seconds` thresholds. + +Failure of a test for an advertised resource type is a failure, not a silent +skip. + +## Training scenario + +The reference training scenario exposes an existing shared sandbox account. A +generic connected-platform simulator adds and later modifies a creative +without a learner AdCP creative call. The reference seller advertises only +`creative` coverage until campaign, money, assignment, and reporting mutation +paths pass the same completeness tests. Its hosted production deployment MUST +also keep the capability disabled until the feed and shared resource snapshot +survive restarts for the advertised retention window. The learner: + +1. registers the account change subscriber; +2. obtains C0 and snapshots the shared account; +3. observes signed external-create and external-modification notifications; +4. drains the feed after each wake-up; and +5. repairs the named authoritative reads. + +The exercise teaches that the account is not exclusively managed by the buyer +and that a webhook is a wake-up, not the source of current truth. + +## Compatibility and rollout + +This is an additive optional wire surface but a new normative behavior for a +seller that advertises it. It therefore targets 3.2, not a 3.1 patch. + +Older clients receive no new event implicitly. Sellers emit +`account.change_recorded` only after explicit 3.2 capability negotiation and +explicit subscription. The task is absent when unsupported. + +The draft requires schema, documentation, SDK generation, compliance, +training-agent, and certification changes.
