Subject: [PATCH 1/2] Meter v1 projection history bytes in Core's canonical
 unit

Server #812 (#770) makes PHP's Waterline v1 projection count history bytes
as Core's HistoryBudget::sizeOfEvent does: the event type's bytes plus its
payload encoded with JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE, the
unit DW_V2_LIMIT_HISTORY_TRANSACTION_BYTES limits everywhere else. Native,
like published PHP through 2.11.5, counted each whole event's JSON with its
id, sequence and time and escaped Unicode.

Native now uses the canonical unit for the byte limit and for the stored
summary's history_size_bytes. #812's LegacyV1Projection::normalize, run on
the published 2.11.5 image's Core, counts the bare test source's two events
as 1280 and 402 bytes (1682 in all, where the old unit gave 1870); native
matches.

Hold until the shared fixture reference moves to a Server release carrying
#812: the waterline-import fixture records history_size_bytes from the
published reference.

Subject: [PATCH 2/2] Move the parity reference to published Server 2.11.7

Published 2.11.7 (Core 2.15.7) replaces 2.11.5 as the reference the
shared fixtures compare native and embedded against (#863). 2.11.6 is
skipped: its repeated bridge-adapter update answered 500 (#861, fixed in
#862).

2.11.7 counts a v1 projection's history bytes in Core's canonical unit
(#770), so waterline-import records five smaller history_size_bytes
values. Native already meters the same way (previous commit). No other
fixture expectation changes.

+# October 29, the parity reference moves to published 2.11.7
+
+- **Before.** The Shared Server fixtures compared native and embedded
+  against published Server 2.11.5 (Core 2.15.1).
+- **Reference.** Published Server 2.11.7, Core 2.15.7, as General published
+  it and Security accepted it (#861):
+  - source `f55f90e54a213872f1c164a1b22c082d859c18aa`;
+  - index `sha256:96e3e7de8c58f31bfb1ef4d5bddddc2678f4684f5cb3505e6e9ddc6fa3f7f625`;
+  - linux/amd64 `sha256:be7c2288ff935396262d743590530b204fac11b76582e56a525cc81a8da840d3`;
+  - linux/arm64 `sha256:7dbc3db050fec05ea5cd10e07ac8399ecf3e285d593bca32979a2320f02a104f`.
+
+  `tests/Fixtures/ServerParityBaselines/php-2.11.7.json` records it. The
+  SDK, CLI, Waterline and sample-app pins are unchanged.
+- **Why not 2.11.6.** A local survey of published 2.11.6 found that a
+  repeated bridge-adapter update answered `500` (#861). 2.11.7 carries the
+  fix (#862).
+- **Survey.** Every fixture in `tests/Fixtures/ServerParity` was recorded
+  locally against the 2.11.7 amd64 image, SQLite, maintenance loop running,
+  except `service-calls` (local SQLite lock pressure) and
+  `visibility-current-runs` (it needs the published CLI artifact CI
+  provides). Results:
+  - 72 of 74 pass unchanged, `bridge-adapters` among them: 2.11.7 gives the
+    intended answers at all three of its published-defect steps;
+  - `schedule-catalog` fails locally the same way on 2.11.5;
+  - `waterline-import` changes as expected (below).
+- **Expectation change.** Server #812 (#770) counts a v1 projection's
+  history bytes as Core's `HistoryBudget::sizeOfEvent` does: the event
+  type's bytes plus its payload as `json_encode` with
+  `JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE`. That is the unit
+  `DW_V2_LIMIT_HISTORY_TRANSACTION_BYTES` limits everywhere else.
+  `waterline-import` records five `history_size_bytes` values:
+
+  | Export | 2.11.5 | 2.11.7 |
+  | --- | --- | --- |
+  | project | 5431 | 4713 |
+  | running | 2683 | 2445 |
+  | failed | 5425 | 4707 |
+  | offsets | 6242 | 5336 |
+  | bare | 1856 | 1668 |
+
+  No other value in that fixture changed.
+- **Native.** The prepared meter change (`e0ed32a6`, held since October 27
+  for this move) counts each event the same way, for the byte limit and
+  for the stored summary.
+- **Local checks before the pull request.**
+  - `waterline-import` was recorded against a fresh 2.11.7 harness and
+    against a native image built from this branch. Both pass, and
+    `compare` accepts the pair. The 2.11.7 recording equals the stored
+    contract observation (with the five new sizes) exactly.
+  - The Rust library and integration suites pass (634 and 359).
+  - The node unit suite passes, except the PHP image-context test,
+    which fails the same way on a clean `main` checkout here because of
+    local ignored state.
+- **Not changed here.** The `bridge-adapters` contract still accepts the
+  published-defect answers of 2.11.1 to 2.11.5. 2.11.7 no longer gives
+  them, so a later change can make that contract exact.
