+### Documentation
+
+- **The engine plan's headline numbers were stale, and two changelog fragments
+  collided with real PR numbers (#7572).** Documentation and metadata only.
+
+  `docs/engine-plan.md` still listed the two worst rows of the v0.5.1299 sweep at
+  their pre-fix values, both of which have since moved by an order of magnitude:
+  `object_deep_clone` from 657.0 ms / 37.5× bun to **40 ms** (~2.3× bun, and
+  **0.67× node — a win**) via #7540, and `map_1m` from 1233.7 ms / 4.8× bun to
+  **309.1 ms** (1.40× bun, **0.96× node — a win**) via #7561. The
+  `json_polyglot` `field_access` inversion — the optimized configuration running
+  2.2× *slower* than the unoptimized one — is closed by #7537 and #7539:
+  2984 ms σ 136 / 219 MB becomes **1809 ms σ 17.3 / 155 MB**, an 8.3× collapse in
+  σ, and turning the tape on is no longer worse than turning it off.
+
+  **A stale plan is not cosmetic — it is how effort gets spent on a
+  non-problem.** Three times this campaign a ticket was picked up and profiled
+  from a headline number that had already collapsed: #7510 (33.6% → 11%),
+  `layout_forget_object` (14.5% → 3.0% → 1.7%), and `layout_note_slot`
+  (7.5% → 0.03%, correctly closed with **no code at all**). The re-synced
+  section now carries that instruction in place: re-measure the row before
+  profiling it.
+
+  The v0.5.1299 table is **kept intact rather than overwritten**. It was a single
+  measurement event at 11 runs per cell; the fixes above were each measured
+  individually, on the same pinned quiet mini, as part of the change that made
+  them. Splicing individually measured rows back into a sweep table would claim a
+  coherence the numbers do not have, so fixed rows are annotated in place and the
+  deltas live in their own section attributed to the PR that moved them. The
+  artifact still owes a fresh sweep, which stays blocked on #7475.
+
+  Also records #7566's landing (workstream A of the #7469 construction campaign:
+  the inline bump allocator at `new` sites inside loops, 1.81× on `churn_alloc`
+  at +0 bytes for non-loop sites, and the honest 1.4% `tree` cost), together with
+  the finding that the measurement justifying the previous default had *inverted*
+  without anyone re-checking it — and the Mach-O negative result, that there is
+  no local-exec TLS model and `-Ztls-model=local-exec` leaves the `blr` through

+  Separately, two fragments were named with an issue number rather than their PR
+  number, landing on numbers belonging to different changes:
+  `7565-iterator-no-silent-truncation.md` → **7567** (#7565 is the
+  `_tlv_get_addr` change) and `7566-macos-gap-snapshot-fallback.md` → **7568**
+  (#7566 is the inline bump allocator). Left alone, `cut_release_notes.sh` folds
+  them under the wrong PR, and two distinct changes sharing a number make the
+  notes unreadable at exactly the point nobody can still check them.
+
+  The rule is worth stating because the failure is systematic, not careless: a
+  fragment written *before* its PR exists has to guess the number. Open the PR
+  first and name the fragment from the number it is assigned — which is how this
+  entry was written.

+**Workstream A has landed (#7566, v0.5.1324): the inline bump allocator is back
+at `new` sites inside loop bodies**, outlined everywhere else.

+
+It reaches the full unconditional-inline ceiling on the allocation-heavy shapes
+at **+0 bytes for every site not in a loop** (verified by per-function IR
+differential, not by assertion). `tree` pays **1.4%** — it allocates in loops so
+it inlines, but its time is dominated by copying and promotion, so it takes the
+bloat without the win. That is the honest cost of a static proxy.
+
+**The measurement that justified the previous default had inverted, and nobody
+had re-checked it.** The outlined form was made default on "−45 IR lines/site
+AND ~17% faster"; the size half still holds (~268 bytes/site) but the speed half
+is now **1.81x the wrong way**, because everything *around* the allocation got
+cheaper (#7474, #7486, #7487, #7501, #7525, #7532, #7535, #7536, #7552) until
+the surviving FFI call dominated what the inline bump's bloat costs. A default
+chosen on a measurement is only as current as that measurement.

+Recorded so it is not re-attempted: **Mach-O has no local-exec TLS model.**
+Building the entire runtime with `-Ztls-model=local-exec` leaves the `blr`

+is what inlining does and what #7565 did structurally.
