#182 persisted accepted response_event rows with distinct observed/received clocks, but two buyer-facing holes remained on 7a72ee1:
load_response_event_receipts advertised fail-closed on gapped sequences and then accepted 1,3.
The Korean persist test recorded item 2 on the original in-memory ledger, not on the reloaded prefix.
A buyer who answers item 1, loses the process, and continues must freeze the same scoring request as an uninterrupted control.
Prefer this head over #182, #174, #53, snapshot-only #151, stale overlapping draft #201, and #201-line draft #208. #208 does not fail closed on time rebinding and splits ledger/clocks across two queries. Do not land those persist slices in parallel.
This is independent of #195 (response HTTP), #159 (command-auth honesty), #158 (participant persist), and #151 (completed snapshot reload). Do not fold those slices into this head.
What
Receipt reload now enforces contiguous server_sequence1..=n before returning clocks.
The Korean path persists item 1, reloads, records item 2 on the reloaded ledger, and freezes the same ScoringRequest as a never-restarted control.

@seonghobae, you've reached your PR review limit, so we couldn't start this review.
Next review available in:29 seconds
Limit details: You’ve used all 1 included review currently available under your plan.
You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.
How can I continue?
After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.
To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.
How do review limits work?
CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.
For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.
This change affects continuation from persisted response receipts, but the current head can still accept writes after a damaged sequence and then fail during reload; it also leaves a database validation mismatch and incomplete recovery proof. These correctness and data-integrity risks could strand or mis-handle buyer sessions, so merge should wait for fixes.

Stale comment
Verdict: unique reload/gap slice is SOUND. load_response_event_receipts rejects 1,3 through require_contiguous_server_sequence. The Korean persist path records item 1, reloads that prefix, records item 2 on the rebuilt ledger, and freezes the same scoring request. Neighbor session prefixes stay isolated.
Do not merge: required checks are not a confirmed terminal-success exact-head set, and this run is not an independent last-push approval. HTTP POST /v1/sessions/{session_ref}/responses stays on the #195 lineage. Do not open another gap/reload successor unless this head accepts a gapped receipt or records item 2 on the pre-restart ledger.

Review
7de134b is a sound persist/reload landing for the Korean IPIP Quick restart: persist item 1, reload receipts with distinct observed/received clocks, record item 2 on the rebuilt ledger, freeze the same ScoringRequest as the uninterrupted control. 1,3 fails closed on both load_response_ledger and load_response_event_receipts. Exact replay is idempotent. Sequence reuse, time rebinding, inverted/zero clocks, neighbor session_ref isolation, and recovery COPY of both timestamps are tested. Schema names are two-word snake_case. Isolation stays READ COMMITTED.
Prefer this head over #182, #174, #201, #208, #53, and snapshot-only #151. Do not merge those persist slices beside this one.
#223 (4552bc8) is the same slice opened minutes later. Do not land both. #223 is tighter on the receipt API: it rebuilds ResponseLedger before returning clocks, so duplicate identities fail closed on load_response_event_receipts itself. This head only checks contiguous 1..=n on receipts and defers identity conflicts to load_response_ledger. The function docstring still says "conflicting" history fails closed here. Under intact unique constraints that hole is closed by the database; the suite already drops constraints for other fail-closed arms, so the honesty gap is real for that fixture class.
Residual, not a buyer-path blocker under intact schema
load_response_event_receipts does not run ResponseLedger::from_persisted before returning clocks. Copy #223's require_contiguous_receipt_history or drop "conflicting" from this function's contract.
persist_response_event will insert a gapped sequence. Reload then fail-closes. Domain record() keeps the buyer path contiguous; write-time prefix enforcement is still missing.
Out of scope on this head
HTTP POST /v1/sessions/{session_ref}/responses stays on #195. Do not fold transport, participant persist, or snapshot reload here.
Merge gates
Not an approval. Author is seonghobae. Independent last-push approval and required checks on the unchanged exact head remain the merge gates. Never self-approve. After this lands, keep response HTTP on #195 and do not open a third persist-landing PR unless this head regresses continue-from-reload or gapped receipts.
The reason will be displayed to describe this comment to others. Learn more.
Insert succeeds for any unused positive server_sequence. A caller can persist sequence 3 with no 1..=2 prefix; reload then fail-closes and the Korean path cannot continue. Domain record() assigns contiguous sequences, so the buyer test stays green, but the adapter itself does not enforce the prefix it later requires.
If this landing wants write-time fail-closed, reject a gap against MAX(server_sequence) for the session before insert. Otherwise say persist trusts the domain ledger and only reload is fail-closed.

Review — continue from reload and fail closed on gapped receipts
Unique slice on 5c66242 / tip 7de134b is SOUND. Prefer this head over #208, #182, and earlier persist-only response-event PRs.
What this head does
load_response_event_receipts reads ORDER BY server_sequence and requires sequence == index + 1. A stored 1,3 prefix is InvalidSequence, not a silently accepted scoring input.
ResponseLedger::from_persisted rebuilds the same prefix; the Korean IPIP Quick restart records item 2 on that reloaded ledger and freezes the same ScoringRequest as an uninterrupted control.
Neighbor session prefixes stay isolated. Recovery COPY asserts both observed and received clocks.
7de134b drops an untestable timestamptz overflow arm so the exact branch-coverage gate can pass.
Residual, not merge-blocking
Persist still accepts a gapped insert. Reload fails closed. Do not invent the missing event on this branch.
HTTP response recording remains outside this slice.
Operator
Do not fold session start (#218), scoring-worker bind (#217), or item-delivery reload (#216) into this PR.
Qualifying approval stays with an independent reviewer. Merge only unchanged 7de134b after then-live required checks are terminal-success. Do not self-approve. Do not open another gapped-receipt successor unless this head accepts 1,3 or continues from the original in-memory ledger instead of the reloaded prefix.

Review (exact head 7de134b)
This is the mid-session response_event persist landing. Prefer over #182, concurrent #223, #174, #201, #208, #53, and snapshot-only #151.
A Korean IPIP Quick path can persist item 1, restart, continue item 2 from the reloaded ledger, and freeze the same scoring prefix. load_response_event_receipts fails closed on a gapped 1,3 prefix. Neighbor sessions stay isolated. Recovery COPY keeps 1_700_000_000_000 / 1_700_000_000_250. The untestable checked_add overflow arm is gone.
Do not add HTTP onto this PR. Response HTTP is #195. Do not land #182 or #223 beside this head.
Independent last-push approval from seonghobae is still required. This review is not an approval.
Pushed the #81 recovery fixture: processing restore rows now seed claim_deadline_at, and COPY must keep the exact source deadline. This unblocks integration_consumption_claim_deadline_shape. Do not merge until exact-head checks and independent last-push approval succeed. Never self-approve.
Rebuild the persisted response ledger before exposing receipt clocks so contiguous sequence history with conflicting client/server identities fails closed for direct scoring or TEPP callers.
Record the second event on the same ledger so only the extra session unique
index fires, not the known sequence unique. rustfmt the receipt-conflict and
sequence-gap tests so Runtime CI can proceed past fmt.
Hourly loop: exact-head rustfmt failed, and unexpected_unique_constraint_and_negative_sequence_fail_closed expected Database(_) but the second event reused sequence 1 so response_event_session_sequence_unique classified as SequenceConflict. Pushed 3d8cbec9: record both events on one ledger so only the extra session unique index fires, plus rustfmt for receipt-conflict/sequence-gap tests. Do not merge until exact-head checks and independent last-push approval succeed. Never self-approve.

- Around line 6-9: Update the numeric-like reference checks in migration 0020
for all four columns to include the full-width and Arabic decimal/thousands
separators already rejected by normalized_reference: ．, ٫, ٬, and ，. Keep the
existing digit requirement and numeric-pattern validation unchanged.
In `@src/postgres_response_event.rs`:
- Around line 446-462: Update both overflow test blocks around
unix_ms_from_system_time to handle checked-add returning None explicitly instead
of silently skipping assertions. Preserve the InvalidTimestamp assertion when
the timestamp can be constructed, and make any platform-dependent skip visible
through the repository’s established explicit-skip mechanism.

use that same PostgreSQL 18 reference author name; make no other citation
changes.
In `@docs/architecture/UML.md`:
- Line 339: Update the “Note over DB” sequence note to describe only the target
persistence/reload semantics, removing the “Active PR” status wording and
PR-specific lifecycle reference. Keep the accepted response_event rows and
distinct observed/received clocks behavior clear, while leaving PR status
tracking to the existing traceability entry.
In `@docs/TRACEABILITY.md`:
- Line 137: Remove the PR preference ranking sentence beginning “Prefer this
head” from the traceability entry, keeping the implementation scope and
protected-main status statements intact. Move that merge-operation guidance to
the appropriate PR description or roadmap if such a destination is already
established.
In `@src/postgres_response_event.rs`:
- Around line 314-327: Extract the two constraint-name literals used by
classify_unique_violation into descriptive uppercase constants, then match
against those constants for ConflictingReplay and SequenceConflict. Keep the
existing Database fallback unchanged and place the constants where
migration-related constraint names are clearly centralized.
- Around line 255-256: Refactor load_response_event_receipts and
load_response_ledger so receipt loading constructs and returns the validated
ResponseLedger once, allowing load_response_ledger to reuse it without
recollecting or revalidating events. Remove the redundant
require_contiguous_receipt_history validation path while preserving failure
behavior for gaps or duplicate receipts, and update
gapped_or_duplicate_receipt_history_fails_closed to match the new return type.
- Around line 386-396: Update the transaction isolation validation around
require_read_committed so each transaction performs the SHOW
transaction_isolation check at most once, rather than repeating it for every
persist_response_event or load_response_event_receipts call. Move the check into
a transaction-scoped wrapper or enforce it through the caller contract while
preserving rejection of non-read-committed transactions.
- Around line 364-369: Update postgres_timestamptz to use checked_add when
adding the duration to UNIX_EPOCH, converting an overflow or unavailable result
into ResponseEventPersistenceError::InvalidTimestamp instead of allowing a
panic; preserve the existing zero-timestamp validation.
Apply the same fix in `@docs/architecture/AS_BUILT_SCHEMA.md` around lines 61 -
64: 동일한 범위 초과 덧셈과 checked_add remediation을 지적합니다.
In `@src/response.rs`:
- Around line 88-103: Extract the shared reference-normalization and
payload-digest validation used by from_persisted and record into a common
helper. Update both paths to call it so they retain identical validation rules
and errors, including empty and non-canonical digest handling.
- Around line 295-311: Update the event validation loop to use HashSet-based
tracking for server_event_ref and client_event_ref duplicates instead of
rescanning prior events. Preserve the existing ServerReferenceConflict and
IdempotencyConflict errors, sequence validation, and event-order semantics while
making duplicate checks linear in the number of events.

Hourly loop: rust FAIL on exact head 3d8cbec9 was clippy::doc_markdown (PostgreSQL rustdoc). Pushed 5a11276a. Independent last-push review is still required; this comment is not approval.
Persist of sequence 2 into an empty session ledger returned Inserted.
The next contiguous sequence is now MAX(server_sequence)+1, or 1 when
the session has no rows, so a gap cannot become a durable prefix.
Linux line coverage missed unix_ms overflow behind checked_add None and
the receipt SELECT ? when response_event is absent. Extract
millis_from_duration and load receipts against a missing relation.
The isolated query_one `?` in classify_existing_event was the remaining
uncovered production line. Name the lookup and fail closed when the
relation is absent.
The isolated ? after query_existing_event_row left one Linux llvm-cov
line and branch unexecuted. Call classify_existing_event against a
missing search_path so the fail-closed Database arm is taken.
The stored-clock compare short-circuited after a received-time-only
replay, so the observed-at AND arm never failed closed. Replay the same
event identity with a later observed clock and the original receipt time.
Linux llvm-cov left next_contiguous_sequence and its saturating_add
closure unexecuted because only persist called them. The lib test takes
missing-relation, empty-prefix, and MAX+1 arms on that copy.
Linux llvm-cov left persist/load as unused instantiations after the
sequence helper test. Call both against a missing search_path so the
library copies take the Database arm.
Linux llvm-cov still left one production line after the missing-relation
lib calls. Repeatable Read persist/load now takes the UnsupportedIsolation
arm and formats the operator-facing message on that copy.
The last uncovered production line stayed on the isolation helper copy
that persist/load inlined. Invoke it directly under Repeatable Read and
READ COMMITTED.

- Around line 382-388: Update the sequence-allocation logic around the
MAX(server_sequence) query to retrieve COUNT(*) and MAX(server_sequence)
together, returning InvalidSequence for non-positive values, count/max
mismatches, or when calculating the next sequence would overflow; only derive
the next value from a validated contiguous prefix. Add a RED test that seeds
only sequence 2, verifies saving sequence 3 fails with InvalidSequence, and
confirms the response-event row count is unchanged.

Linux llvm-cov left classify_unique_violation unexecuted because persist
inlined it. The lib test takes client-unique, sequence-unique, and
non-constraint Database arms on that copy.
Linux llvm-cov left Error::source on the library copy unexecuted because
only integration tests formatted the operator-facing errors. The lib test
now takes Database source and the no-source arms.
Superseded by current-main reconciliation #284. The replacement carries every non-documentation source/migration/test path from this PR on protected-main baseline 503a4e640eeba0f5e126fa4c4078d8d21aebb93b, adds an explicit RED→GREEN current-base lineage, and adds the missing real-PostgreSQL Rust-equivalent durable-reference parity/revalidation contracts. The older documentation delta is intentionally not copied verbatim where it would overstate active-PR behavior as as-built truth; #284 instead records the slice as IMPLEMENTED_ON_ACTIVE_PR in canonical traceability and an indexed response-persistence architecture view. Do not merge both.

Why
#182 persisted accepted
response_eventrows with distinct observed/received clocks, but two buyer-facing holes remained on7a72ee1:load_response_event_receiptsadvertised fail-closed on gapped sequences and then accepted1,3.A buyer who answers item 1, loses the process, and continues must freeze the same scoring request as an uninterrupted control.
Prefer this head over #182, #174, #53, snapshot-only #151, stale overlapping draft #201, and #201-line draft #208. #208 does not fail closed on time rebinding and splits ledger/clocks across two queries. Do not land those persist slices in parallel.
This is independent of #195 (response HTTP), #159 (command-auth honesty), #158 (participant persist), and #151 (completed snapshot reload). Do not fold those slices into this head.
