Self-contained class with its own OpenAI client for summarization.
Uses auxiliary model (cheap/fast) to summarize middle turns while
protecting head and tail context.

Improvements over v2:
  - Structured summary template with Resolved/Pending question tracking
  - Filter-safe summarizer preamble that treats prior turns as source material
  - Historical (reference-only) section headings replace "Next Steps"/"Remaining Work" to avoid reading as active instructions
  - Clear separator when summary merges into tail message
  - Iterative summary updates (preserves info across multiple compactions)
  - Token-budget tail protection instead of fixed message count
  - Tool output pruning before LLM summarization (cheap pre-pass)
  - Scaled summary budget (proportional to compressed content)
  - Richer tool call/result detail in summarizer input

    Live cached-gateway transcripts stamp ``_db_persisted`` during incremental
    flushes.  Shallow ``.copy()`` propagates that marker into the post-rotation
    compressed list, so ``_flush_messages_to_session_db`` skips every row when
    writing to the new child session (#57491).

    This strips at the copy site (clearest intent, and cheap), but the
    authoritative guarantee is the single terminal sweep in ``compress()``
    (``_strip_persistence_markers``): no message may leave ``compress()``
    carrying ``_db_persisted`` regardless of how many intermediate copy sites
    a future refactor adds.

    session-store persistence marker.

    ``compress()`` copies protected head/tail messages out of the live
    cached-gateway transcript, which stamps ``_db_persisted`` on every message
    over the life of the session.  If any copied dict keeps that marker, the
    rotation flush to the child session skips it and the compacted transcript is
    lost from ``state.db`` (#57491).  Stripping at each copy site is necessary
    but *positional* — a copy site added after the assembly loops would re-leak.
    This single terminal sweep makes the guarantee structural instead: run it
    once on the fully-assembled list so the invariant holds no matter where the
    copies happened.  Mutates in place (the dicts are compaction-local copies).

    - a RAW ``skill_view`` body that was never demoted (it sat inside the

    ``skill_names`` was extracted from the summarizer INPUT before the LLM
    call. For every skill whose canonical marker (``_skill_pruned_marker``)
    is absent from the model's output, append it under a ``## Pruned
    Skills`` section. Presence is checked against the SAME canonical string
    the emit sites produce — a paraphrased or renamed marker counts as
    dropped and is restored (the original PR checked the literal
    ``[SKILL_PRUNED]``, which never matches the emitted ``[SKILL_PRUNED:``
    form, so it duplicated markers that HAD survived).

    The appended block is plain body text: it never carries a handoff
    prefix, the merged-summary delimiter, or a start-of-content scaffolding
    marker, so ``classify_summary_content`` / todo-snapshot flag handling
    are unaffected. The block is routed through ``_redact_compaction_text``
    like every other compaction-boundary text.

    A skill is protected (lower-cased set) when any of these hold:

    - its most recent ``skill_view`` call sits within the last
      ``_SKILL_PRUNE_RECENT_WINDOW`` messages (just loaded / just reloaded);
    - its most recent ``skill_view`` call sits inside the protected tail
      (at or after *prune_boundary*);
    - its name is mentioned in a user message inside the protected tail
      (the user is actively steering work that depends on it).

    Protection applies to the ordinary Phase-1/2 prune only. The Pass-4
    pressure demotion deliberately ignores it: when the protected region
    itself exceeds the soft budget, exempting skill bodies would recreate
    the #61932 dead-end shape.

    Compaction summaries persist across sessions and are re-injected into
    every subsequent summarizer prompt, so this boundary uses strict mode:

    - ``force=True`` — deliberately overrides ``security.redact_secrets:
      false``. That opt-out targets *live tool output* (e.g. working on the
      redactor itself); a summary is a persistence boundary where a leaked
      credential keeps re-entering prompts indefinitely.
    - ``redact_url_credentials=True`` — OAuth callback codes, magic-link
      tokens, and URL userinfo never need to survive summarization the way
      they must survive live navigation flows.

    Counts the message content plus the **full** ``tool_call`` envelope —
    ``id``, ``type``, ``function.name`` and JSON structure — not just
    ``function.arguments``.  Counting only the arguments string undercounted
    assistant turns that fan out into parallel tool calls by 2-15x (a
    4-tool-call turn measures ~73 vs ~1,090 real tokens), so the protected
    tail overshot ``tail_token_budget`` and compression became ineffective.
    See issue #28053.

    Also counts provider replay fields (``codex_reasoning_items`` etc. —
    see ``_REPLAY_BUDGET_KEYS``).  The preflight "should I compress?"
    estimator sees the full message shape, so the tail walk must use the
    same size class; otherwise an assistant message with tiny visible
    content but large hidden replay blobs is protected as if it were small,
    the post-compression session stays near the context limit, and
    compaction re-fires continuously (#55572).  Accounting-only: replay
    fields are never mutated or pruned here.

    preserving JSON validity.

    The ``function.arguments`` field on a tool call is a JSON-encoded string
    passed through to the LLM provider; downstream providers strictly
    validate it and return a non-retryable 400 when it is not well-formed.
    An earlier implementation sliced the raw JSON at a fixed byte offset and
    appended ``...[truncated]`` — which routinely produced strings like::

        {"path": "/foo/bar", "content": "# long markdown
        ...[truncated]

    i.e. an unterminated string and a missing closing brace. MiniMax, for
    example, rejects this with ``invalid function arguments json string``
    and the session gets stuck re-sending the same broken history on every
    turn. See issue #11762 for the observed loop.

    This helper parses the arguments, shrinks long string leaves inside the
    parsed structure, and re-serialises. Non-string values (paths, ints,
    booleans) are preserved intact. If the arguments are not valid JSON
    to begin with — some model backends use non-JSON tool arguments — the
    original string is returned unchanged rather than replaced with
    something neither we nor the backend can parse.

    LLMs sometimes return non-string parameter values (e.g. bool, int) for
    tool calls.  Calling ``len()`` / ``.count()`` / slicing on those causes
    ``TypeError`` / ``AttributeError`` which crashes context compression.
    This helper coerces any value to ``str`` so downstream code can assume
    a string is always returned.

    Used during the pre-compression pruning pass to replace large tool
    outputs with a short but useful description of what the tool did,
    rather than a generic placeholder that carries zero information.

    Returns strings like::

        [terminal] ran `npm test` -> exit 0, 47 lines output
        [read_file] read config.py from line 1 (1,200 chars)
        [search_files] content search for 'compress' in agent/ -> 12 matches

    Never raises: models sometimes emit non-string argument values (bool,
    int, None) and the args here come from persisted session history, so a
    single malformed historical call must not crash compression — which
    retries on the same history and would crash-loop. Individual branches
    coerce the values they slice/measure (keeping summaries informative);
    this wrapper is the backstop for anything they miss.

    ``model_thresholds`` maps substring keys to override fractions.  The
    longest matching key wins (so ``glm-5.2-1M`` beats ``glm-5.2`` when the
    model is ``glm-5.2-1M``).  When no override matches, or when
    ``model_thresholds`` is empty/None, ``default`` is returned unchanged.

    This is a module-level helper so plugin context engines (e.g. LCM) can
    import and reuse the same resolution logic as the built-in compressor.

        Session end (CLI exit, gateway expiry, session-id rotation) goes
        through this method rather than ``on_session_reset()`` (/new, /reset).
        The original fix (#38788) only cleared ``_previous_summary``, but the
        same cross-session contamination risk applies to every per-session
        variable that ``on_session_reset()`` clears: stale
        ``_ineffective_compression_count`` can suppress compression in a
        subsequent live session; ``_summary_failure_cooldown_until`` can block
        summary generation; ``_last_compress_aborted`` can make callers think
        compression is still aborted; ``_last_aux_model_failure_*`` can surface
        stale error warnings; ``_last_summary_dropped_count`` /
        ``_last_summary_fallback_used`` can produce misleading user warnings.

        ``compress()`` already guards ``_previous_summary`` leakage at the
        point of use; this is defense-in-depth that resets the full per-session
        surface the moment the owning session ends.

        A fresh compressor on a resumed session starts with
        ``compression_count == 0`` and, historically, an in-memory-only
        ineffective counter — so a guard armed (1 strike) or tripped
        (2 strikes) before a process restart silently disarmed, and a
        near-threshold session could re-compact once per restart forever
        (#54923). The counter now round-trips through the session row like
        the failure cooldown and the fallback streak.

        After ``threshold_tokens`` is (re)computed from the ratio-based

        is clamped to the current context length so a cap larger than
        the model's window is a no-op (the ratio-based threshold wins).

        The base value is ``effective_input_budget * threshold_percent``, floored
        at ``MINIMUM_CONTEXT_LENGTH`` so large-context models don't compress
        prematurely at 50%. BUT that floor degenerates at small windows: for a
        model whose ``context_length`` is at/below the minimum (e.g. a 64K
        local model), ``max(0.5*64000, 64000) == 64000`` makes the threshold
        equal the ENTIRE window — auto-compression can never fire because the
        provider rejects the request before usage reaches 100% (#14690).

        When the floor would meet or exceed the context window, trigger at
        ``_MIN_CTX_TRIGGER_RATIO`` (85%) of the window — high enough that a
        small model uses most of its context before compacting, but below
        100% so compaction fires before the provider rejects the request.

        The provider reserves ``max_tokens`` of output space out of the same
        window, so the usable INPUT budget is ``context_length - max_tokens``.
        With a large ``max_tokens`` (e.g. 65536 on a custom provider) the input
        budget is materially smaller than the raw window, and a threshold based
        on the full window lets the session hit a provider 400 before compaction
        fires (#43547). The percentage and the degenerate-window check below both
        operate on the effective input budget. ``max_tokens=None`` (provider
        default) conservatively assumes no reservation (full window).

        ``estimate_request_tokens_rough(..., tools=...)`` intentionally
        overestimates schema-heavy requests so Hermes compresses before a
        provider rejects the payload. After a successful compressed API call,
        though, provider ``prompt_tokens`` are a better signal than repeating
        compaction from the same rough schema overhead. Defer only while the
        rough estimate has grown modestly since a request the provider proved
        fit under the threshold.

        Returns a ``(should_compress, reason)`` tuple instead of a bare bool so
        callers can tell *why* compression is skipped when it is skipped while
        the context is already over threshold. ``reason`` is ``None`` unless
        compression is needed but blocked:

        * ``"cooldown:<seconds>"`` — the summary LLM is recovering from a
          recent 429/transient failure; compression is deferred to avoid the
          freeze loop described in #11529.
        * ``"ineffective"`` — anti-thrashing has backed off because the last
          two compressions each saved <10%.

        When ``reason`` is non-``None`` the session is over its compression
        threshold yet cannot shrink — callers should surface a warning so the
        user knows the model may silently stop answering (the context keeps
        growing until it hits the hard provider limit). Without this signal an
        over-threshold session fails opaquely.

        Includes anti-thrashing protection: if the last two compressions
        each saved less than 10%, skip compression to avoid infinite loops
        where each pass removes only 1-2 messages.

        Instead of a generic placeholder, generates a summary like::

            [terminal] ran `npm test` -> exit 0, 47 lines output
            [read_file] read config.py from line 1 (3,400 chars)

        Also deduplicates identical tool results (e.g. reading the same file
        5x keeps only the newest full copy) and truncates large tool_call
        arguments in assistant messages outside the protected tail.

        Walks backward from the end, protecting the most recent messages that
        fall within ``protect_tail_tokens`` (when provided) OR the last
        ``protect_tail_count`` messages (backward-compatible default).
        When both are given, the token budget takes priority and the message
        count acts as a hard minimum floor — capped at
        ``_MAX_TAIL_MESSAGE_FLOOR`` so a default ``protect_last_n=20`` cannot
        freeze a whole run of bulky tool outputs against pruning.

        When the protected region itself still exceeds the soft tail budget
        (``protect_tail_tokens * 1.5``), a pressure pass demotes large
        completed tool/file outputs *inside* that region while keeping a
        short recent floor verbatim (issue #61932).

        Returns (pruned_messages, pruned_count).

        Runs the Phase-1 prune (``_prune_old_tool_results``) WITHOUT the
        compression summary phase, gated on ``proactive_prune_tokens`` rather
        than the (much higher) full-compression threshold. On large-window
        models ``should_compress()`` (≈50% of the window) rarely fires, so old
        tool outputs otherwise ride in history and are re-sent verbatim on every
        subsequent turn; this reclaims them early with no quality-risky LLM
        summarization.

        Protects the recent tail by message COUNT (``protect_last_n``), never by
        ``tail_token_budget`` — the latter is derived from the 50% compression
        threshold (≈100K tokens on a 1M window) and would protect the entire
        session, pruning nothing.

        ``_prune_old_tool_results`` runs all three deterministic passes:
        (1) dedup byte-identical tool results — keeps the newest full copy and
        back-references older exact duplicates ANYWHERE in the list (including
        the protected tail), so no unique content is ever lost; (2) summarize
        non-tail tool results larger than ``min_prune_chars``; (3) truncate
        oversized tool_call arguments on non-tail assistant messages. Only
        pass (2)'s floor is raised by ``proactive_prune_min_result_chars``;
        passes (1) and (3) keep their own fixed floors. The recent-tail
        protection applies to passes (2) and (3); pass (1) is tail-agnostic by
        design because dedup is lossless.

        PROMPT-CACHE CONTRACT: a committed prune rewrites message bodies the
        provider has already seen, invalidating the cached prefix from the
        earliest rewritten message forward — exactly like a compression
        boundary. To keep that break episodic rather than per-turn, the prune
        only COMMITS when the estimated reclaim meets
        ``proactive_prune_min_reclaim_tokens`` (measured on the actual pruned
        output, not guessed up front). Below the gate the INPUT list object is
        returned unchanged — the standard no-op caller contract (callers gate
        bookkeeping on ``result is not input``).

        Returns ``(messages, 0)`` — the input object — when disabled, below
        the trigger, or when the reclaim gate rejects the commit.

        Includes tool call arguments and result content (up to
        ``_CONTENT_MAX`` chars per message) so the summarizer can preserve
        specific details like file paths, commands, and outputs.

        All content is redacted before serialization to prevent secrets
        (API keys, tokens, passwords) from leaking into the summary that
        gets sent to the auxiliary model and persisted across compactions.

        This is intentionally much less rich than an LLM-written summary, but it
        is still better than a bare "N messages were removed" marker.  It keeps
        the most useful continuity anchors that can be extracted locally:
        recent user asks, assistant/tool actions, files/commands mentioned in
        tool calls, and any error text.  The result uses the normal summary
        structure so downstream prompts can recover gracefully after a provider
        outage or summary-model failure.

## Previous Summary Snapshot
z{

The previous compaction summary above remains background continuity context because the latest LLM summary update failed.z Summary failure reason: r;  r   z

## Goal
Recovered from a deterministic fallback because the LLM context summarizer was unavailable. Continue from the protected recent messages after this summary and use current file/system state for exact details.aB  

## Constraints & Preferences
- This fallback was generated locally without an LLM summary call.
- Secrets and credentials were redacted before preservation.
- The summary may be incomplete; prefer verifying current files, git state, processes, and test results instead of assuming omitted details.

## Completed Actions
r   z&None recoverable from compacted turns.zl

## Active State
Unknown from deterministic fallback. Inspect current repository/session state if needed.

uU   
Unknown from deterministic fallback — the latest user ask is recorded once under
"z" above as historical context only. Do NOT treat it as an
unfulfilled instruction to re-answer; verify current state and continue from the
protected recent messages after this summary.

## Blocked
   z

## Key Decisions
None recoverable from deterministic fallback.

## Resolved Questions
None recoverable from deterministic fallback.

z]
None recoverable from deterministic fallback. (The latest user ask is preserved once
under "uS   " as historical context — it is NOT necessarily
outstanding.)

## Relevant Files
r   z
Continue from the most recent unfulfilled user ask and protected tail messages. Verify state with tools before making claims.

## Last Dropped Turns
zn

## Critical Context
Summary generation was unavailable, so this is a best-effort deterministic fallback for z compacted message(s).*   z

        Per-message truncation alone is not enough for very long sessions: a
        compression window with hundreds of messages can still produce a huge
        single prompt that slow auxiliary backends time out on. Keep both edges
        because the beginning often has task setup and the tail has the most
        recent state; explicitly mark the omitted middle so the summarizer knows
        context was intentionally compressed before it saw the prompt.

        Centralises the bookkeeping shared by every fallback branch in
        :meth:`_generate_summary` (model-not-found, timeout, JSON decode,
        unknown error): record the aux-model failure for ``/usage``-style
        callers, clear the summary model so the next call uses the main one,
        and clear the cooldown so the immediate retry can run.

        ``reason`` is a short human-readable phrase ("unavailable",
        "timed out", "returned invalid JSON", "failed") that is interpolated
        into the warning log.

        Uses a structured template (Goal, Progress, Decisions, Resolved/Pending
        Questions, Files, Remaining Work) with explicit preamble telling the
        summarizer not to answer questions.  When a previous summary exists,
        generates an iterative update instead of summarizing from scratch.

        Args:
            focus_topic: Optional focus string for guided compression.  When
                provided, the summariser prioritises preserving information
                related to this topic and is more aggressive about compressing
                everything else.  Inspired by Claude Code's ``/compact``.

        Returns None if all attempts fail — the caller should drop
        the middle turns without a summary rather than inject a useless
        placeholder.

input verbatim — the exact words they used. This includes:
- Explicit task assignments ("<specific user task>")
- Questions awaiting an answer ("<specific user question>")
- Decisions awaiting input ("<option A or B?>")
- Ongoing discussions where the assistant owes the next substantive reply
A conversation where the user just asked a question IS an active task — the
task is "answer that question with full context". Do NOT write "None" merely
because the user did not issue an imperative command; reserve "None" for the
rare case where the last exchange was fully resolved and the user said
something like "thanks, that's all".
If multiple items are outstanding, list only the ones NOT yet completed.
This historical snapshot must identify the latest unresolved user input precisely. Examples:
"User asked: '<exact latest user request>'"
"User asked: '<exact latest user question>' — needs investigation + answer"
"User chose <option>; awaiting implementation of <specific next step>"
If the user's most recent message was a reverse signal (stop, undo, roll
back, never mind, just verify, change of topic) that supersedes earlier
work, write the reverse signal verbatim and DO NOT carry forward the
cancelled task. Example: "User asked: '<exact reverse signal>' — earlier
in-flight work is cancelled."

Note that credentials were present, but do not preserve their values.z)
TEMPORAL ANCHORING: The current date is z. When an action has already been carried out, phrase it as a completed, dated, past-tense fact rather than an open instruction. For example, rewrite "email John about the proposal" as "Sent the proposal email to John on z." Never leave a finished action worded as if it still needs doing, and never invent a date for work that has not happened yet.

## Goal
z

## Constraints & Preferences
u  

## Completed Actions
[Numbered list of concrete actions taken — include tool used, target, and outcome.
Format each as: N. ACTION target — outcome [tool: name]
Example:
1. READ config.py:45 — found `==` should be `!=` [tool: read_file]
2. PATCH config.py:45 — changed `==` to `!=` [tool: patch]
3. TEST `pytest tests/` — 3/50 failed: test_parse, test_validate, test_edge [tool: terminal]
Be specific with file paths, commands, line numbers, and results.]

## Active State
[Current working state — include:
- Working directory and branch (if applicable)
- Modified/created files with brief note on each
- Test status (X/Y passing)
- Any running processes or servers
- Environment details that matter]

u  
[Work currently underway — what was being done when compaction fired]

## Blocked
[Any blockers, errors, or issues not yet resolved. Include exact error messages.]

## Key Decisions
[Important technical decisions and WHY they were made]

## Resolved Questions
r   uT   

## Relevant Files
[Files read, modified, or created — with brief note on each]

u  
[What remains to be done — framed as STALE context for reference only. The agent must NOT resume this work unless the latest user message explicitly asks for it.]

## Critical Context
[Any specific values, error messages, configuration details, or data that would be lost without explicit preservation. NEVER include API keys, tokens, passwords, or credentials — write [REDACTED] instead.]

u9  
[If any [SKILL_PRUNED: ...reload with skill_view(...)] markers appear in the input,
repeat each one verbatim here — copy the exact text, do NOT paraphrase, summarize,
or describe them. These markers tell the agent which skills must be reloaded before
use. If none appear, omit this section entirely.]

Target ~u    tokens. Be CONCRETE — include file paths, command outputs, error messages, line numbers, and specific values. Avoid vague descriptions like "made some changes" — say exactly what changed.
zD
Write only the summary body. Do not include any preamble or prefix.z

You are updating a context compaction summary. A previous compaction produced the summary below. New conversation turns have occurred since then and need to be incorporated.

PREVIOUS SUMMARY:
z

NEW TURNS TO INCORPORATE:
u  

Update the summary using this exact structure. PRESERVE all existing information that is still relevant. ADD new completed actions to the numbered list (continue numbering). Move items from "In Progress" to "Completed Actions" when done. Move answered questions to "Resolved Questions". Update "Active State" to reflect current state. Remove information only if it is clearly obsolete. CRITICAL: Update "## Active Task" to reflect the user's most recent unfulfilled input — this includes any question, decision request, or discussion turn that the assistant has not yet answered. Only write "None" if the last exchange was fully resolved.

z

Create a structured checkpoint summary for the conversation after earlier turns are compacted. The summary should preserve enough detail for continuity without re-reading the original turns.

TURNS TO SUMMARIZE:
z

Use this exact structure:

z

FOCUS TOPIC: "zy"
This compaction should PRIORITISE preserving all information related to the focus topic above. For content related to "u  ", include full detail — exact values, file paths, command outputs, error messages, and decisions. For content NOT related to the focus topic, summarise more aggressively (brief one-liners or omit if truly irrelevant). The focus topic sections should receive roughly 60-70% of the summary token budget. Even for the focus topic, NEVER preserve API keys, tokens, passwords, or credentials — use [REDACTED].r  )rt  r  r  r  r  r   )rm   rl   )taskmain_runtimerL   rt  )_resolve_task_provider_model)rt  rL   r  i  )r  r  r  r  r  r  rl   z9Context compression LLM returned empty content (provider=autoz model=r  r  zno llm provider configuredz$no auxiliary LLM provider configuredztContext compression: no provider available for summary.

        stale directive it carried stays embedded in the body.

            whole message would hide the preserved content.

                     |S )a  Fix orphaned tool_call / tool_result pairs after compression.

        Two failure modes:
        1. A tool *result* references a call_id whose assistant tool_call was
           removed (summarized/truncated).  The API rejects this with
           "No tool call found for function call output with call_id ...".
        2. An assistant message has tool_calls whose results were dropped.
           The API rejects this because every tool_call must be followed by
           a tool result with the matching call_id.

        This method removes orphaned results and strips orphaned tool_calls
        from assistant messages so the message list is always well-formed.

        Previous approach inserted stub ``role="tool"`` results for orphaned
        tool_calls.  That caused a secondary failure: the pre-API
        ``repair_message_sequence()`` uses ``tc.get("id")`` to track known
        call IDs while this sanitizer uses ``call_id || id``.  When the two
        disagree (Codex Responses API format: ``id != call_id``), stubs get
        silently dropped by the repair pass, re-exposing the original orphans.
        Stripping at the source avoids this entire class of mismatch.

        ``protect_first_n`` keeps the first N non-system messages verbatim so
        the original task framing survives the FIRST compaction. But applying
        it on every subsequent pass fossilizes those early turns — they're
        re-copied into each child session and never summarized away, so old
        user messages become immortal and grow the head unboundedly across a
        long session (#11996). Once the session has been compressed at least
        once, the early turns are already captured in the handoff summary, so
        there's no need to keep re-protecting them: decay to 0 (the system
        prompt is still always protected separately by _protect_head_size).
        After a restart, infer that decayed state from handoff summaries in the
        resumed-head region; disk-persisted restarts rely on the content prefix,
        while the metadata branch covers in-process handoff messages.

        ``protect_first_n`` is defined as *additional* messages protected
        beyond the system prompt.  The system prompt (if present at index 0)
        is always implicitly protected — it's load-bearing context that
        must never be summarised away.  This keeps semantics stable across
        call paths where the system prompt may or may not be included in
        the ``messages`` list (e.g. the gateway ``/compress`` handler
        strips it before calling compress()).

        The ``protect_first_n`` portion DECAYS after the first compression
        (see _effective_protect_first_n) so early user turns don't fossilize
        across repeated compactions (#11996).

        Examples (first compaction):
          protect_first_n=0 → system prompt only (or nothing if no system msg)
          protect_first_n=3 → system + first 3 non-system messages
        After the first compaction: system prompt only.

        If the boundary falls in the middle of a tool-result group (i.e.
        there are consecutive tool messages before ``idx``), walk backward
        past all of them to find the parent assistant message.  If found,
        move the boundary before the assistant so the entire
        assistant + tool_results group is included in the summarised region
        rather than being split (which causes silent data loss when

        after *head_end*, or -1.

        A "user-visible reply" is an assistant message with non-empty
        textual content — i.e. one that the WebUI / TUI / SessionsPage
        rendered as a bubble the operator could read. We deliberately
        skip assistant messages that contain only ``tool_calls`` (and
        no text), because those render as small "calling tool X"
        indicators and aren't what the reporter means by "the output
        of the last message you sent" (#29824).

        Context-compaction handoff banners can also carry
        ``role="assistant"``. They are internal continuity state, not a
        user-visible reply, so ignore them both as text-bearing anchors and
        as candidates for the fallback below. This mirrors the user-role
        summary exclusion in ``_find_last_user_message_idx``.

        Falling back to the most recent non-summary assistant message of ANY kind
        only kicks in when no content-bearing assistant message exists
        in the compressible region — typically a fresh session that
        just started a multi-step tool sequence with no prior reply
        to anchor. In that case the agent fix is a no-op and the
        existing user-message anchor carries the load.

        WebUI / TUI / SessionsPage bug (#29824). Without this anchor,
        ``_find_tail_cut_by_tokens`` can leave the user's most recent
        visible assistant response inside the compressed middle region —
        especially when the conversation has a single oversized tool
        result or a long stretch of tool-call/result pairs after the
        last assistant reply. The summariser then rolls that reply up
        into the single ``[CONTEXT COMPACTION — REFERENCE ONLY]`` block
        persisted as ``role="user"`` or ``role="assistant"``. From the
        operator's perspective the WebUI session viewer
        (``web/src/pages/SessionsPage.tsx``) and the TUI chat panel
        both suddenly show the opaque "Context compaction" block in the
        slot where they were just reading the assistant's actual reply:

            User:       "i cant see the output of the last message you
                         sent, i did see it previously, however now see
                         'context compaction'"

        Mirror of ``_ensure_last_user_message_in_tail`` but anchors on
        the last assistant-role message. Re-runs the tool-group
        alignment so we don't split a ``tool_call`` / ``tool_result``
        group that immediately precedes the anchored message — orphaned
        tool messages would otherwise be removed by
        ``_sanitize_tool_pairs`` and trigger the same data-loss symptom
        we're trying to prevent.

        Context compressor bug (#10896): ``_align_boundary_backward`` can pull
        ``cut_idx`` past a user message when it tries to keep tool_call/result
        groups together.  If the last user message ends up in the *compressed*
        middle region the LLM summariser writes it into "Historical Pending User Asks",
        but ``SUMMARY_PREFIX`` tells the next model to respond only to user
        messages *after* the summary — so the task effectively disappears from
        the active context, causing the agent to stall, repeat completed work,
        or silently drop the user's latest request.

        Fix: if the last user-role message is not already in the tail
        (``messages[cut_idx:]``), walk ``cut_idx`` back to include it.  We
        then re-align backward one more time to avoid splitting any
        tool_call/result group that immediately precedes the user message.

        Causal Coupling guard (#22523): the final ``max(last_user_idx,
        head_end + 1)`` clamp can push the cut *past* the user message when
        the user sits at ``head_end`` (the first compressible index) — the
        only case where ``head_end + 1 > last_user_idx``.  That splits the
        turn-pair: the user lands in the compressed region without its
        assistant reply, so the summariser records it as a pending ask and
        the next session re-executes the already-completed task.  When this
        split is unavoidable, push the cut *forward* to ``pair_end`` so the
        full pair (user + reply + tool results) is summarised together and
        correctly marked as completed.

        Generalizes ``_ensure_last_user_message_in_tail`` to preserve an
        arbitrary number of recent user messages.  This prevents the token-
        budget-based tail cut from consuming recent conversation turns
        when large tool outputs fill the budget.

        When *n* <= 1, delegates directly to the existing single-message
        method for byte-identical regression safety.

        If the conversation has fewer than *n* user messages, the earliest
        available user message is used without error.

        Only REAL actionable user turns count toward N — the collector uses
        the same ``_is_actionable_user_turn`` /
        ``_is_synthetic_compression_user_turn`` pair as
        ``_find_last_user_message_idx``, so blank platform echoes, compaction
        handoffs, continuation markers, and todo-snapshot rows never consume
        a slot (#69291 bug class).

        A user message is already a clean boundary — there is no
        tool_call/result group that spans across it, so
        ``_align_boundary_backward`` is intentionally NOT called.
        Calling it can pull the cut past the user message into the
        preceding assistant(tool_calls)→tool group and split it (#22566).

        the budget is reached. Returns the index where the tail starts.

        ``token_budget`` defaults to ``self.tail_token_budget`` which is
        derived from ``summary_target_ratio * context_length``, so it
        scales automatically with the model's context window.

        Token budget is the primary criterion.  A bounded message-count floor
        keeps a short run of recent turns verbatim even when the budget is
        exhausted, but the budget is allowed to exceed by up to 1.5x to avoid
        cutting inside an oversized message (tool output, file read, etc.). If
        even that floor exceeds 1.5x the budget, the cut is placed right after
        the head so compression still runs.

        Never cuts inside a tool_call/result group.  Always ensures the most

        Algorithm:
          1. Prune old tool results (cheap pre-pass, no LLM call)
          2. Protect head messages (system prompt + first exchange)
          3. Find tail boundary by token budget (~20K tokens of recent context)
          4. Summarize middle turns with structured LLM prompt
          5. On re-compression, iteratively update the previous summary

        Blank platform-echo user rows trailing the latest actionable user
        turn are removed in the same cheap pre-pass phase as tool-result
        pruning — i.e. BEFORE any summary-abort early return. An aborted
        compression can therefore still hand back a modified list (echoes
        stripped, no turns summarized); this mirrors the long-standing
        Phase-1 pruning behavior, which likewise survives an abort.

        After compression, orphaned tool_call / tool_result pairs are cleaned
        up so the API never receives mismatched IDs.

        Args:
            focus_topic: Optional focus string for guided compression.  When
                provided, the summariser will prioritise preserving information
                related to this topic and be more aggressive about compressing
                everything else.  Inspired by Claude Code's ``/compact``.
            force: If True, clear any active summary-failure cooldown before
                running so a manual ``/compress`` can retry immediately after
                an auto-compression abort.  Auto-compress callers pass False.
            memory_context: Optional provider-supplied context to preserve in

    Public API for consumers outside the compressor (memory providers,
    frontends) that must not treat compaction summaries as real user or
    assistant turns — e.g. fact extraction harvesting the compactor's own
    output as user statements (#57682).

    Prefers the in-process ``COMPRESSED_SUMMARY_METADATA_KEY`` marker and
    falls back to the content heuristics in ``_is_context_summary_content``
    (which cover the merged-into-tail and historical-prefix cases), because
    the metadata key is stripped by the wire sanitizers and does not survive
    all session-store round-trips.
