Release v0.51.765 — Wave 1 batch (6 fix-class PRs)

Batched release of 6 gate-certified, file-disjoint contributor fix PRs. Each was individually
gate-certified GREEN (Codex SAFE + full suite + per-PR tests) at its current head; this combined
stage was re-gated as a unit.

Included

• fix(#5273): sync active viewed count on done settle #5276 (@rodboev) — sync active viewed count on done-settle; clears a stale unread badge after compaction (fixes Unread indicator persists on large sessions after compaction and viewing #5273)
• fix(#5270): preserve first WebUI continuation context for CLI sessions #5274 (@rodboev) — preserve first WebUI continuation context for CLI-origin sessions (fixes CLI-origin session continued in WebUI loses immediate prior-turn continuity #5270)
• refactor(streaming): split terminal-failure transcript evaluator (#5141) #5272 (@nankingjing) — refactor: split terminal-failure transcript evaluator (behavior-preserving; Follow up terminal failure settlement to avoid duplicate transcript merge #5141)
• fix(sidebar): remove menu-deleted sessions optimistically #5256 (@franksong2702) — remove menu-deleted sidebar sessions optimistically (fixes bug(sidebar): context-menu Delete keeps session row visible until backend cleanup finishes #5255)
• fix(#5250): let settings search results escape the menu clip #5254 (@rodboev) — let settings search results escape the menu clip (fixes Settings search results dropdown gets clipped by the panel boundary #5250)
• Fix Transparent Streaming live anchor scene replay #5257 (@franksong2702) — fix Transparent Streaming live anchor scene replay ordering

Gate

• Files are disjoint across the 6 PRs (no shared-file overlap → no silent semantic conflict).
• Combined-stage Codex regression gate: SAFE TO SHIP (no regression, core flows intact).
• Full pytest suite: 11128 passed, 82 skipped, 1 xfailed, 2 xpassed. The only 2 "failures" are
  the pre-existing test_scheduled_jobs_profile_isolation.py serial-ordering artifact (passes
  12/12 in isolation; no PR here touches cron code) — environmental, not a regression.
• ESLint runtime gate CLEAN, ruff forward gate CLEAN, node --check clean on all touched JS.

CHANGELOG updated under [Unreleased] → Fixed with per-author credit.

Greptile Summary

Batched release of 6 gate-certified fix PRs covering unread-badge correctness after compaction, CLI-to-WebUI session continuity, transparent-streaming live anchor ordering, optimistic sidebar deletion, settings-search dropdown overflow, and a behavior-preserving refactor of the terminal-failure transcript evaluator.

• Unread badge / viewed sync (fix(#5273): sync active viewed count on done settle #5276): Computes a unified completedMessageCount from a 4-level fallback chain and advances _markSessionViewed to fire before the sidebar cache update, preventing a stale unread dot on the actively-viewed session after compaction.
• CLI-origin WebUI continuity (fix(#5270): preserve first WebUI continuation context for CLI sessions #5274): Adds _session_messages_have_prefix to detect when a sidecar's context-messages are a proper prefix of the live CLI transcript, then refreshes session.messages on chat-start so the stitched CLI history is authoritative for the first WebUI follow-up; the compaction/compression-anchor path is preserved.
• Transparent Streaming live anchor ordering (Fix Transparent Streaming live anchor scene replay #5257): Dispatches renderLiveAnchorActivityScene to a new _renderLiveAnchorActivitySceneTransparent renderer before the compact-only guard, idempotently replacing legacy live surfaces via data-anchor-scene attributes, and guards data-anchor-settled-scene-row to settled-only nodes so live rows no longer masquerade as final anchors.

Confidence Score: 4/5

Safe to merge; all six changes are narrowly scoped, file-disjoint, and backed by targeted tests covering the specific failure scenarios they fix.

The Python-side changes (models, routes, streaming) are straightforward and thoroughly tested with integration-style fixtures. The JS-side transparent-stream renderer (_renderLiveAnchorActivitySceneTransparent) is the most intricate change — ~70 lines of sequential DOM mutations whose correctness depends on selector ordering and attribute stamping that unit tests approximate with a custom FakeElement harness rather than a real browser. The logic reads correctly and the idempotency test passes, but live/final anchor ordering in a real browser session is inherently harder to verify statically than the backend changes.

static/ui.js — the new transparent live renderer and its interaction with the existing compact renderer; worth a quick smoke-test in a transparent-streaming session after merging.

Important Files Changed

Filename	Overview
api/models.py	Adds _session_messages_have_prefix helper and expands reconciled_state_db_messages_for_session to prefer the longer authoritative CLI transcript over a stale sidecar context prefix on the first WebUI continuation; compression-anchor path is preserved when the CLI override is not triggered.
api/routes.py	Adds refresh_cli_messages keyword arg to _get_or_materialize_session; when True and the session is a CLI session, refreshes messages from get_cli_session_messages if the DB copy is a prefix-compatible superset of the sidecar. _handle_chat_start passes this flag, and test mocks updated to accept **kwargs.
api/streaming.py	Behavior-preserving refactor: extracts _turn_transcript_lacks_final_assistant_answer (operates on an already-merged transcript) and makes _merged_transcript_lacks_final_assistant_answer a thin delegating wrapper that first merges then delegates; original signature and semantics unchanged.
static/messages.js	Computes unified completedMessageCount via a 4-level fallback (payload count → payload messages.length → S.session.message_count → S.messages.length) and advances _markSessionViewed to fire before the sidebar cache update so the actively-viewed session never shows a stale unread dot after compaction.
static/ui.js	Adds _renderLiveAnchorActivitySceneTransparent for transparent-stream live activity and dispatches to it before the compact-mode guard; conditionally stamps data-anchor-settled-scene-row (settled only) vs data-anchor-live-scene-row (live only) to prevent live rows from masquerading as final anchors. Complex DOM manipulation verified by idempotency tests.
static/sessions.js	Context-menu Delete now passes an immediate ()=>Promise.resolve() beforeDelete hook through the existing deleteSession path so the sidebar row disappears optimistically instead of lingering until the slow server round-trip completes.
static/index.html	Settings nav buttons wrapped in a new .settings-menu-items div to move scroll ownership off the parent #settingsMenu, allowing the absolutely-positioned search-results dropdown to escape the clip boundary.
static/style.css	Sets #settingsMenu to overflow: visible and introduces .settings-menu-items as the scrollable flex column for nav buttons, enabling the search dropdown to overflow the panel boundary.
tests/test_issue5273_active_done_viewed_sync.py	New Node.js-executed harness verifying all four fallback branches of completedMessageCount and confirming the pre-cache-update viewed sync for actively-viewed sessions across compaction scenarios.
tests/test_issue5270_cli_webui_continuity.py	Four integration tests covering fresh materialization, claimed-sidecar refresh, chat-start flag propagation, and writability preservation for the CLI-to-WebUI continuity fix.
tests/test_live_to_final_anchor_visible_order.py	Adds two new tests: a structural assertion verifying transparent dispatch precedes compact gate, and a Node.js-executed DOM test confirming idempotent render, legacy surface hiding, and correct attribute stamping for the transparent live renderer.
tests/test_issue5141_terminal_failure_transcript_evaluator.py	New tests verifying the refactored evaluator split: both the direct _turn_transcript_lacks_final_assistant_answer path and the delegating wrapper produce identical results, and the wrapper's delegation is verified via mock patching.
tests/test_session_active_profile_authorization.py	Two existing monkeypatches updated to accept **_kwargs on _get_or_materialize_session to stay compatible with the new refresh_cli_messages keyword argument.
tests/test_issue3975_cron_reply_materialization.py	One-line update: materialize stub now accepts **_kwargs to accommodate the new keyword argument on _get_or_materialize_session.
tests/test_issue5250_settings_search_dropdown_escape.py	New Playwright-based browser hit-test verifying the search results dropdown extends below #settingsMenu's visible boundary and is click-target-accessible.
