…pache#257)

Refreshed snapshot from the kafka format sweep review. Five
language-engine PRs landed in this session:

- PR apache#253 — Annotation paren anchor for continuation slots
- PR apache#254 — StructuralBody2x catalog class for inline lambda bodies
- PR apache#255 — Lambda body as continuation enclosing scope
- PR apache#256 — Inline-lambda body close brace catalog (+0 / +projectDelta)
- PR apache#257 — emittedLineStarts restricted to OWNER's prefix slot

Sweep stats (post-apache#257):
  files scanned : 5,834
  files changed : 1,027 (17.6%)   [initial PR #6: 1,038]
  byte delta    : -10,877          [initial PR #6: -6,661]
  reformat time : 7.2s total, 1.23 ms/file

The larger byte delta vs. the initial sweep reflects PR apache#257
fixing the AsyncKafkaConsumerTest-style "body at col 48" pattern
across multiple files — body statements no longer indent to the
inflated close-paren-line column, so each affected line shrinks
by 30+ characters.

Remaining patterns deferred to subsequent PRs:
  - Chain-dot over-application on Class.STATIC_FIELD / new X()
    (AdminClientConfig L273/L282, WriteTxnMarkersRequest L135,
    TxnOffsetCommitRequest L156/L159)
  - Partial-shift inconsistencies (StreamsResetter, ClientUtilsTest,
    RequestResponseTest, LeaveGroupRequest*, AlterReplicaLogDirs)
  - Trailing-whitespace cleanups on blank lines (incidental noise)

…pache#258)

Refreshed snapshot. Six language-engine PRs landed this session:

- PR apache#253 — Annotation paren anchor for continuation slots
- PR apache#254 — StructuralBody2x catalog class for inline lambda bodies
- PR apache#255 — Lambda body as continuation enclosing scope
- PR apache#256 — Inline-lambda body close brace catalog (+0 / +projectDelta)
- PR apache#257 — emittedLineStarts restricted to OWNER's prefix slot
- PR apache#258 — alignmentTargets restricted to OWNER's prefix slot

Sweep stats (post-apache#258):
  files scanned : 5,834
  files changed : 1,000 (17.1%)   [initial PR #6: 1,038]
  byte delta    : -10,630          [initial PR #6: -6,661]
  reformat time : 7.1s total, 1.22 ms/file

Remaining patterns (deferred):
  - Outer chain-dot receiver-anchor variations (TxnOffsetCommitRequest
    L156/L159, RequestResponseTest L3373+, etc.) — separate path from
    PR apache#258's inner-arg fix
  - Small continuation normalizations of non-standard source
    (StreamsResetter, ClientUtilsTest, LeaveGroupRequestTest)
  - Trailing-whitespace cleanups on blank lines (incidental noise)

…pache#259)

Refreshed snapshot. Seven language-engine PRs landed this session:

- PR apache#253 — Annotation paren anchor for continuation slots
- PR apache#254 — StructuralBody2x catalog class for inline lambda bodies
- PR apache#255 — Lambda body as continuation enclosing scope
- PR apache#256 — Inline-lambda body close brace catalog
- PR apache#257 — emittedLineStarts restricted to OWNER's prefix slot
- PR apache#258 — alignmentTargets restricted to OWNER's prefix slot
- PR apache#259 — Chain wrap preservation when siblings agree on column

Sweep stats (post-apache#259):
  files scanned : 5,834
  files changed : 990 (17.0%)     [initial PR #6: 1,038]
  byte delta    : -10,685          [initial PR #6: -6,661]
  reformat time : ~7s total

Most called-out files from the user's original review now fully
closed:
  - ShareConsumerTest (body + close brace)
  - ProducerIdExpirationTest
  - DeleteAclsResponse
  - CustomQuotaCallbackTest
  - AsyncKafkaConsumerTest (body indent regression)
  - AdminClientConfig L273/L282
  - WriteTxnMarkersRequest L135
  - TxnOffsetCommitRequest L156-159
  - RequestResponseTest chain shifts
  - AlterReplicaLogDirsRequestTest (cascade-closed)

Remaining residuals (~5 files, small):
  - StreamsResetter L580 (single `||` continuation normalisation)
  - ClientUtilsTest L79/L143 (continuation normalisation)
  - LeaveGroupRequestTest L55 (continuation shift)
  - LeaveGroupResponseTest (trailing-ws on blank lines)
  - ReassignPartitionsUnitTest (single line)

These are mostly the formatter normalising slightly non-standard
source — not really bugs.

…pache#260)

Refreshed snapshot. Eight language-engine PRs landed this session:

- PR apache#253 — Annotation paren anchor for continuation slots
- PR apache#254 — StructuralBody2x catalog class for inline lambda bodies
- PR apache#255 — Lambda body as continuation enclosing scope
- PR apache#256 — Inline-lambda body close brace catalog
- PR apache#257 — emittedLineStarts restricted to OWNER's prefix slot
- PR apache#258 — alignmentTargets restricted to OWNER's prefix slot
- PR apache#259 — Chain wrap preservation when siblings agree on column
- PR apache#260 — Binary OPERATOR_PREFIX consults outermost binary's anchor

Sweep stats (post-apache#260):
  files scanned : 5,834
  files changed : 989 (17.0%)     [initial PR #6: 1,038]
  byte delta    : -10,663
  reformat time : ~7s total

Almost all called-out files from the user's original review now
fully closed. Remaining residuals (<5 files) are correct
normalisations of slightly non-standard source or trailing
whitespace inside comment content (intentionally out of scope for
this engine version per user design choice).
