In `@adrs/02-consume-corporate-action-mutations.md`:
- Around line 85-90: Revise the ADR’s corporate-action identity and mutation
state machine to align with the existing FreezeHoldId::corporate_action
contract: explicitly define the migrated hold key, retain the previous
window/hold identity on updates, release and clean up the prior window before
applying the replacement, and ensure deletes release the active hold and remove
pending transitions using the stored prior identity.
- Around line 59-66: The ADR’s abuse-test requirements omit explicit
hold-ownership attacks. Extend the real SSE decoder-to-reconciliation test suite
to cover both update and delete attempts targeting the active operator hold and
another action’s hold, using two actions on the same underlying and an active
operator hold, while verifying only the originating action’s own validated hold
can be affected.
- Around line 47-50: Update the ADR’s Alpaca dividend event validation contract
to explicitly enumerate the accepted event_type values and any required region
scoping. Define unsupported or newly introduced event types as rejected with an
explicit failure, ensuring they cannot be silently ignored or dropped.
- Around line 93-97: Define the historical-replay bootstrap behavior in the ADR,
including the exact cursor value or absence of a cursor used on first install
and how it is propagated as since_id/Last-Event-Id. Specify retention recovery
when the stored cursor predates replayable history, including how the system
detects it, rebuilds authoritative state, establishes a new cursor, and only
then accepts live traffic.
- Around line 90-91: Expand the transaction boundary described in the mutation
replay flow to include every reconciliation write: scheduler projection, pending
transitions, active holds, revision, mutation result, and replay cursor.
Explicitly assign all of these writes to the same SQLite transaction, and add
crash-boundary tests covering each possible commit ordering to ensure the cursor
cannot advance while reconciliation remains incomplete.

56-58: 🩺 Stability & AvailabilityConfirm poison-event resume semantics.
If reconnecting from the blocked event ID replays that event inclusively, later updates or deletes can stay stuck behind it; if it resumes after the blocked event, the recovery guidance should say so explicitly.

118-123:⚠️ Potential issue | 🟠 MajorMake terminal alignment failures recoverable.
The marker is set after enqueue succeeds, but startup is also required to re-arm terminal alignment because the projection remains pending. After enqueue succeeds, the projection is no longer pending under the stated marker semantics. Define a durable terminal-failure state, or set
reconciled_event_idonly after alignment succeeds. Test enqueue success, terminal failure, restart, and re-arm.As per path instructions, specifications should define durable recovery states and their transitions.

deleting absent actions unless a completeness watermark is present. Preserve the

- Around line 1669-1674: Update the scoped-projection repair protocol to
establish an SSE cutover watermark before or during snapshot acquisition, apply
only buffered mutations newer than that boundary, and deduplicate the boundary
event when replaying. Atomically commit the rebuilt projection with the

1173-1176: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftUse one identity for each corporate-action hold.
Line 1174 identifies the hold by the complete window. Line 1626 identifies it by the stable Alpaca action ID. The supplied scheduler also derives the hold and job keys from window boundaries in
src/tokenized_asset/schedule.rs:301-390.Two actions with the same window can therefore share a hold or job key. An update that changes the window can also leave the old hold active. Choose one contract. Prefer stable action ID plus revision for the hold and boundary-job identities, or document how the previous window identity is retained and released on every update and delete.
As per path instructions, specifications and designs should receive architectural feedback, including missing instructions.

- Around line 1630-1634: Update the streaming decoder specification to define
durable poison-boundary persistence without requiring an event ID: record the
last accepted cursor, optional provider event ID, typed rejection reason, and
bounded poison fingerprint before gating the feed. Clarify that oversized or
malformed frames without a canonical event ID cannot advance the cursor and
remain gated until operator resolution, and add restart coverage for both cases.
- Around line 1658-1660: Define an explicit maximum size for the repair buffer
used by the replay-retention repair flow, including the unit and overflow
behavior. Require the implementation to check the bound before appending each
frame, abort repair on overflow, and keep minting or issuance gated afterward.
Document and test the overflow case while pagination remains in progress,
covering the boundary and ensuring no additional frame is appended after the
limit is reached.

119-125:⚠️ Potential issue | 🟠 MajorKeep transition-job identity aligned with action-owned hold identity.
This repeats the previously reported identity mismatch. The ADR assigns
FreezeHoldIdby Alpaca action ID, but Lines [122-124] still key transition-job idempotency by the window only. Two actions with identical windows can collapse into one job, while each action requires an independent hold. Align the job key and payload with the action ID and revision, or explicitly define fan-out to every applicable action-owned hold. Keep operator window holds separate.🤖 Prompt for AI Agents

- Around line 211-214: Update the corporate-action repair contract to require
region=us on every request, and validate each returned row so non-us regions are
rejected before repair proceeds. Remove the stale no-region assumption while
preserving the existing pagination and accepted-event-type constraints.
- Around line 54-65: Update the ADR section describing unlisted-underlying
mutations to define retention and compaction: retain only the latest canonical
mutation needed for listing-time promotion, while preserving bounded audit
attribution for accepted event IDs and outcomes. Specify the partitioning,
capacity or TTL policy, and cleanup invariant that prevent unbounded growth,
including when retained data may be removed after listing promotion or
expiration.
- Around line 203-205: The repair design must not rely on an undocumented SSE
watermark or snapshot consistency token. In the documented corporate-actions
flow around the paginated GET snapshot and `since_id` replay, either identify an
exact provider-supported capability proving completeness through B or redesign
the procedure to use a provider-supported consistency protocol.
In `@SPEC.md`:
- Around line 1684-1691: Update the replay-retention repair flow so an empty
buffer does not wait before requesting the snapshot: commit the rebuilt
projection without a cursor, keep the live stream open, and establish the cursor
from the first accepted frame. Restart repair if the stream disconnects before
that frame, while keeping normal consumption and minting gated until a cursor
exists.

77-83: 🩺 Stability & AvailabilityDefine the standard SSE parsing boundary.
The ADR treats malformed payloads as poison events but does not define how
text/event-streambecomes JSON. Standard SSE permits comments, multipledata:lines, blank-line dispatch, andid,event, andretryfields. Passing raw lines to JSON validation can reject valid keepalives or split one JSON event incorrectly. (html.spec.whatwg.org)Specify the parser behavior and test comments, multiline data, CRLF/LF separators, and the relationship between the SSE
idfield and payloadevent_id. If PR#282delegates this to a library, name that library and verify its behavior.Sources: Path instructions, MCP tools

1689-1697: 🩺 Stability & AvailabilityBound snapshot pagination and repair duration.
Lines [1689-1697] require exhausting the paginated snapshot but define no per-request timeout, total repair deadline, maximum page count, or repeated-token check. A stalled provider or a non-advancing
next_page_tokencan keep repair active indefinitely. The frame ceilings do not stop this when no live events arrive. The REST contract usesnext_page_tokenfor pagination. (docs.alpaca.markets)Require request and total-operation deadlines, reject repeated or non-advancing tokens, and test timeout and token-cycle failures while issuance remains gated.
As per path instructions, Markdown review focuses on specification content and cross-layer lifecycle contracts rather than cosmetic formatting.

- Around line 155-156: Update
adrs/02-consume-corporate-action-mutations.md:155-156 to keep the revision
recoverable after enqueueing and terminal failure, rather than marking it
reconciled immediately; update
adrs/02-consume-corporate-action-mutations.md:184-194 to define the terminal
state consistently with that marker semantics; and update SPEC.md:1661-1669 to
mirror the durable transition and restart behavior. Anchor the changes to the
second-phase alignment-job flow and the revision reconciliation marker.
- Around line 143-150: Update the listing-promotion rules so the service-owned
reactor atomically compares retained and current listed event IDs before
creating a promotion revision, preserving the newer listed revision and
preventing overwrite races. Apply this in
adrs/02-consume-corporate-action-mutations.md lines 143-150 and document the
same compare-and-no-overwrite behavior, including race-test coverage, in SPEC.md
lines 1627-1633.
- Around line 61-68: The unlisted canonical mutation state uses an unstable key
that includes underlying, allowing multiple rows for one action; update the
design to key it by (region, action_id) or explicitly supersede older-underlying
rows when newer events arrive, while preserving the cleanup invariant. Apply the
same change in adrs/02-consume-corporate-action-mutations.md lines 61-68 and
SPEC.md lines 1641-1649.
In `@SPEC.md`:
- Around line 1627-1638: Define the alignment behavior for updates whose new
window is already fully elapsed: release the prior action-owned source hold,
safely handle any already-enqueued boundary jobs, and mark the new schedule
revision reconciled without acquiring a replacement hold. Add specification
coverage and tests for both active-to-elapsed and future-to-elapsed updates,
including recovery behavior.
- Around line 1641-1649: Update the unlisted canonical-state specification to
define a durable cursor-echo record tied to the current replay cursor, retaining
the event ID and a bounded canonical fingerprint or payload sufficient to verify
the inclusive replay frame after audit compaction. Extend the accepted-mutation
replay rules to specify how duplicate IDs older than retained audit rows are
resolved using this cursor echo, including the recovery behavior when the
required evidence is unavailable.
- Around line 1677-1704: Update the ingestion specification around the durable
poison, cursor-regression, rejected-anchor, and retention-gap boundaries to
require one deduplicated durable operator alert for each gated state, including
the stored reason, cursor, and fingerprint. Define the alert’s deduplication
identity and require it to clear only when the corresponding boundary is
resolved, such as after an operator restore and successful inclusive replay
verification.

Stack Context
This is the design slice for the automated corporate-actions stack. It replaces the deprecated announcement-polling source introduced in #240; the implementation follows in #282.
Motivation
Advances RAI-1043. Alpaca corporate actions can be inserted, revised, or deleted after a freeze window has been armed. Polling a bounded snapshot cannot prove deletions or reliably rediscover every revised future ex-date, so stale jobs can freeze an underlying on the wrong date or leave it frozen after cancellation.
Solution
Record the decision to consume Alpaca's replayable corporate-actions SSE mutation stream and project its latest revision durably. The ADR defines:
