+
+#### Presentation identity and controlled-browser evidence
+
+At `2026-09-09T08:49:58Z`, the live inventory was **131 open pull requests:
+14 Ready/non-draft and 117 Draft; 14 open non-PR issues**. Protected `main`
+remains `87c4daa1830bac5a5228b6036752ad5633232085`; no GitHub Release exists.
+Ruleset `18156473` still requires one counted approval and seven central required
+workflows. Queued reviewer evidence is non-passing: discard queued, skipped,
+cancelled, absent, predecessor, synthetic, status-only, and model-only evidence.
+
+Issue #292 remains the buyer-visible presentation-identity gap. Draft #293 is
+at exact head `6855e2578ae94279cc9ab4a14527b016e8c049ee` on Ready #229
+`024f63690cf05cfe6f0d4a430f0e18ea8fd2c4d6`. Its reusable lifecycle deliberately
+does not apply reduced motion without a complete restore or disposable-context
+owner. Thus command planning cannot be presented as full profile application.
+Draft successor #298 is at exact head
+`d01f45c2c8ac7b0fc4dbc3d3ada60238732cdf8c` on that #293 head. Its non-force
+merge of #305 repaired an older source contract so it now asserts both that
+ReducedMotion remains a discoverable protocol capability and that the reusable
+planner exposes no media-mutation command. This removes an API/documentation
+contradiction only; #298's Draft checks are skipped and it does not establish
+live Chromium transport, page observation, cleanup, protected-main shipment,
+or release acceptance.
+An active controlled evidence harness is implemented, but it does not establish a
+product Browser Session adapter: its exact browser lane failed 0/3 at session
+creation before navigation, so application, page-observed post-conditions, cleanup
+acceptance, and release remain unproven. Issue #212 owns the sandbox-helper contract;
+the product branch must consume it rather than copy or weaken workflow behavior.
+
+#### Transport-closure verification and test-integrity repair
+
+The current queue also leaves Ready #287 at
+`3975daf48e01a5e9d1cf9fb104a3be1aa03b0402` with exact-head native and central
+checks queued. Its prior CodeQL dispatch outcome was an absent central verdict,
+not a classifier-source finding. No release, protected-main shipment, or approval
+is inferred from local work, a child merge, or queued checks.
