Batch compaction pauses a session for one large summarization once the
window fills. Micro-compaction spreads that cost out: after each completed
turn, `finalize_turn` folds the single oldest un-absorbed exchange
(assistant message plus its tool results) into a rolling summary, so the
work happens in small increments during post-turn idle time instead of one
long stall.
Mechanics:
- a cursor tracks the first message not yet absorbed, recovered from the
transcript's last summary marker when in-memory state is unavailable;
- protected head and tail windows are never touched, so the system prompt
and recent turns stay verbatim;
- the absorbed span is replaced by a marker carrying the usual
`_compressed_summary` metadata, so resume, handoff and `/compress`
treat it exactly like a batch summary;
- `archive_and_compact` keeps the session DB in step, otherwise the
append-only flush would leave the original rows active and a resume
would double-load both summary and originals;
- when the rolling summary itself passes a token threshold it is
defragged: re-summarized in one shot and the cursor jumps to the tail;
- an exchange the summarizer can't handle is retried a bounded number of
times, then skipped, so one poison exchange can't stall every turn.
Keep only the newest summary marker. The rolling summary is cumulative, so
each marker already contains everything the previous ones held; leaving them
stacked near-duplicate copies of the same text, each with its own heading and
end-marker scaffolding, and the transcript grew on every turn instead of
shrinking. Measured over six turns on a 12-exchange conversation with tool
output: 4104 -> 4797 tokens before, 4104 -> 2572 after.
Off switch: `compression.micro_compact: false` (default on).

Covers what it does, the head/tail protection, the cursor and rolling summary, defrag, how the session DB is kept in step, and the failure paths. States the tradeoff up front: compression cost is amortized across turns, at the price of older detail becoming summarized earlier in a session than batch-only compaction would.

`_find_one_exchange`'s docstring described an exchange as "(optional) user message + assistant message + its tool results", but the walk skips past user messages and starts at the assistant, so user turns are never absorbed into the rolling summary. The code is right and the docstring was wrong. Assistant output is largely an account of what was done and survives summarising with little loss. The user's messages are the intent everything else is derived from and cannot be reconstructed from the work that followed — paraphrasing "use the existing helper, don't add a new one" into a summary is how an agent ends up doing the opposite six turns later. They are also cheap: a prompt is normally a tiny fraction of what one tool result costs. Correct the docstring, document the property (and its cost — a floor on how small the middle can get, since user turns accumulate), and add a test so it stays deliberate.

The `_micro_compact` docstring cited "NousResearch#82483" for the resume double-load problem. No such issue exists — the repository's highest number is 74323, so the reference was invented rather than looked up. The reasoning it was attached to is correct and stays: the session flush is append-only, so an in-memory splice alone leaves the original rows active and a resume loads both the summary and the messages it replaced. Only the citation was wrong. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The existing log line reports message counts, which is the least informative number available here: absorbing one tool-heavy exchange can drop hundreds of tokens while moving the count by one. There was no way to answer "is this actually helping?" from a real session. Emit one content-free JSON line per pass, in the same shape as the batch compaction telemetry: before/after tokens, the delta, the size of the absorbed exchange, the rolling summary size, duration, and running per-session totals so a whole run can be read off the last line. No transcript content rides along. Add scripts/micro_compaction_report.py to aggregate those lines into passes, outcome mix, net tokens saved, mean exchange size and durations, with an optional per-session breakdown. Measuring it immediately surfaced something worth documenting: the first pass in a session normally *costs* tokens. The summary marker carries a fixed ~400 tokens of scaffolding, paid on pass one against a single absorbed exchange. From pass two the marker is replaced rather than added, so the overhead is already paid and each exchange is close to pure saving. Break-even is typically the second or third pass. Tests cover the telemetry contract, the cumulative totals, and that first-pass/later-pass shape so nobody reads a single turn and concludes it made things worse. The estimator costs ~5 ms at 600 messages and ~20 ms at 1200, taken twice per pass, post-turn — and only once an exchange is actually in hand, so turns that no-op early pay nothing.

Tokens saved is the wrong headline for this feature. Micro-compaction is not an efficiency optimisation — the same summarization work happens either way. What it buys is (a) that work amortized across turns instead of one stall, and (b) a window kept low enough that a session runs much further before needing a hard compaction at all. Neither shows up in "net tokens saved". A session can save nothing on paper and still be a clear win on both counts. So the telemetry now carries occupancy: tokens_after as a share of the compaction threshold, plus the threshold and resolved window it was computed from. That is the number that says whether a session has headroom left. The report leads with it, and cross-references the batch `compression_attempt` lines already in the log so it can show how often the long pause actually fired — ideally never. Occupancy is read from the cached threshold only. The public `threshold_tokens` property resolves lazily and can issue a synchronous /models probe (NousResearch#32221); telemetry must never be the thing that blocks a turn, so an unresolved window reports null. In practice a pass has already resolved it via the tail calculation, so the field is populated. A test pins the no-forcing behaviour directly against the emitter. The report is pure ASCII: `scripts/check_subprocess_stdin.py` currently dies on a cp1252 console before printing its results, and a diagnostic tool that crashes on the platform it is diagnosing is worse than no tool.

The cursor was set to the pre-splice `exchange_end`. A splice collapses the absorbed span -- an assistant plus its tool results, often four or more messages -- into a single marker, and may also drop a superseded marker further back, so every index after it shifts. The stale cursor therefore overshot, landing inside a *later* exchange's tool group. The next pass's `_find_one_exchange` walked forward from there to the following assistant, so the exchange it had landed inside was never absorbed at all. On tool-bearing conversations micro-compaction was silently doing roughly half the work it should. Traced on a 3-tool-per-exchange transcript: the cursor sat at index 6 when the marker was at 2, and the message count stalled at 32 instead of continuing to 28. Derive the cursor from the marker's actual position in the spliced result instead, which is self-correcting regardless of how much the splice moved. Apply it on the defrag path too, which had the same staleness. Found by a randomized long-horizon harness (480 conversation shapes x 25 passes, varying tool-group sizes and summarizer failure modes) asserting structural and progress invariants after every pass. Existing tests missed it because their fixtures have no tool results, so the absorbed span is one message and nothing shifts. The regression test uses tool groups.

Three corrections, all from measuring a real 3.5 hour session rather than reasoning about the design. "During the idle moment after a response" was wrong. A pass is a real call to the compression model at the end of a turn: the answer has streamed, but the turn does not close until it finishes. Measured 2 to 37 seconds, median around 31, on a small local model. Say so. Add the choice of `auxiliary.compression` model as its own section, because it dominates everything else here. A pass sends only a few thousand tokens but runs every turn, so latency is felt repeatedly, and reasoning models are a poor fit -- merging one exchange into a summary is mechanical work, and a thinking model spends reasoning tokens on it for no benefit. Two measured data points are given as illustrations of the shape, explicitly not as recommendations: the right answer depends on the operator's hardware. Add what a working session actually looks like: occupancy climbing to ~22% and flattening (equilibrium -- 4,841 tokens added between the last two passes, 4,395 reclaimed), zero batch compactions, and reclamation only ramping after the tail budget is crossed. Also state the cost in the same breath rather than burying it. Frame the feature as a tuning option rather than a win: it lets you choose how the compression cost is distributed and which model pays it. It is not a magic bullet and the docs should not imply otherwise. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The rolling summary lives only in memory. A resumed session starts with an empty one while the marker carrying every previously absorbed exchange is still in the transcript. The first pass after a resume therefore built a marker from a single exchange and superseded the marker holding the entire history -- silently discarding everything micro-compaction had accumulated. This was introduced by the supersede fix. Before it, markers piled up wastefully, but nothing was ever lost. Two changes, so a single failure cannot lose data: Rehydrate. When the cursor is recovered by scanning the transcript -- the resume path -- also recover the rolling summary from that marker, so the next pass merges into the existing history instead of replacing it. Extraction uses rfind for the heading because SUMMARY_PREFIX references the heading text itself, so the first occurrence is inside the preamble. Gate superseding. Earlier markers are dropped only when this pass's summary is demonstrably cumulative, i.e. the rolling summary was non-empty going in. If rehydration ever fails, the pass keeps both markers: wasteful, but the history survives. Tests cover the resume path, the failed-rehydration fallback, and the round trip of a summary through a marker. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Review raised whether default-on can be reconciled with the prompt-cache contract in AGENTS.md, which permits mutating past context only for context compression and treats per-conversation caching as sacred. It cannot, and the codebase already says so in its own words. A micro-compaction pass rewrites already-sent history, so it invalidates the cached prefix every turn rather than at an episodic boundary. That is the exact cost the proactive prune gates against: `proactive_prune_min_reclaim_tokens` exists, per its own config comment, to keep rewrites to "one big episodic break instead of a tiny break every tool iteration." Micro-compaction has no equivalent gate -- one exchange per turn means one break per turn, by design. Default to off. An operator who wants the amortized stall can opt in with `compression.micro_compact: true` and accept the tradeoff knowingly; nobody inherits a per-turn cache break from installing an update. Also register the key in config_defaults so it is discoverable and picked up by the update path's new-options check -- it was previously read by agent_init but declared nowhere -- and document the cache cost in docs/micro-compaction.md instead of only the benefit. The measurements behind the feature (occupancy plateau, zero batch compactions) never priced cache invalidation, and the doc now says which numbers a reader would need to measure to justify enabling it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The on/off switch was the only knob. A pass fired after every completed turn, absorbed exactly one exchange, and there was no way to ask for less. Since a pass is also what breaks the prompt-cache prefix, "how often does it run" and "how often do I pay a cache break" are the same question, and it had no answer. Add `compression.micro_compact_every_n_turns` (default 1, clamped to >= 1). At 1 the behaviour is what it was; at 5 you get a fifth of the breaks and a fifth of the reclaim rate. The counter advances per invocation rather than per committed pass, so a turn that finds nothing to absorb still moves the cadence along and cannot wedge it, and a bogus 0 or negative degrades to "every turn" instead of silently disabling compaction. Also expose `micro_compact_defrag_threshold_tokens`, which has been a hardcoded attribute on the compressor with no path from config since it was added. This does not give micro-compaction the prune's reclaim-size gate -- a pass still commits whatever the single absorbed exchange saved. It makes the break frequency tunable, which reaches the same end by absorbing less rather than by waiting for a bigger win. The docs now say that plainly, including that a reclaim threshold is the obvious follow-up and does not exist yet. Tests cover the skip-until-due window, the cursor and prefix staying untouched on skipped turns, the clamp, and that the feature is off unless enabled.

…eserving Two integration bugs found during review of NousResearch#74522, both confirmed with empirical probes against the production message-repair path: 1. Alternation: the summary marker was role="user" and an exchange was a single assistant+tools group, so splicing between two user turns produced user -> marker(user) -> user. The pre-request repair_message_sequence pass (conversation_loop.py, runs before EVERY API call) then merged the marker into the neighbouring real user message: metadata gone, cursor unrecoverable on resume, and the summary text duplicated into the transcript on every later pass (the transcript GREW every turn). Fix: an exchange is now a full agent turn (assistant + tools + follow-up assistant iterations, bounded by user messages), the marker is assistant-role, and superseding an old marker deliberately merges the two adjacent real user turns (plain-text \n\n-join, identical to repair pass 2) so the returned transcript is alternation-valid by construction. Probe result: repairs 0 (was 2), marker survives, no summary leakage. 2. Defrag destroyed user messages: _defrag_rolling_summary serialized the whole remaining middle (user turns included) and spliced it away — 8 of 10 user prompts destroyed in one pass, contradicting the feature's "your messages are never compacted" invariant. Fix: defrag now re-summarizes only the rolling summary TEXT and rewrites the marker content in place; transcript shape, cursor, and user turns untouched. Probe result: 10 of 10 user prompts survive. Also: marker provenance is now COMPRESSED_SUMMARY_HAS_USER_TURN_KEY=False — micro markers absorb only assistant/tool content (NousResearch#64650 invariant), and real user turns remain in the transcript for provenance detection. Adds 5 regression tests (repair-pass integration, alternation on multi-iteration tool turns, defrag user survival, defrag input scope, marker provenance); updates the two existing tests and the design doc to the corrected semantics. 28 tests pass.

Salvage of open #74522 with the feature now opt-in ( |
…ck-typed compressors tests/run_agent/test_proactive_prune_loop_wiring.py builds agents with a MagicMock compressor; getattr(mock, '_micro_compact_enabled', False) returns a truthy auto-attribute, so the hook called _micro_compact on the mock and spliced its (empty-iterating) return over the transcript — wiping all messages before persist (CI slice 7/8 failure). Gate now requires _micro_compact_enabled is True, a callable _micro_compact, and a non-empty list result before touching messages. Same hardening protects production plugin context engines that don't subclass ContextCompressor.
Phase 2 review findings on the salvage branch: C1 (critical): batch and micro summary markers share COMPRESSED_SUMMARY_METADATA_KEY, and compress() never reset micro state. After micro absorbed exchanges 1..k, a batch compaction summarizing 1..m (m>k) could fire; the next micro pass's supersede then dropped the batch marker (whose content the stale rolling summary does NOT contain) and archive_and_compact immediately made the loss durable. Defrag had the same hazard: it rewrote "the newest marker" even if that was a batch marker. Empirically confirmed with a probe (batch marker content destroyed in one pass). Fix, three parts: - Micro-created markers now carry MICRO_COMPACT_MARKER_KEY; supersede and defrag only ever touch micro-tagged markers. Rehydration in _resolve_compact_cursor tags the marker it absorbs (containment proof), which safely covers adopting a batch marker as the new rolling base after a reset. - compress() success path resets micro rolling summary/cursor state so a stale summary can never claim cumulativeness over a batch marker. - Regression tests for both directions plus the reset. W4: _splice_micro_compact_result no longer strips _db_persisted stamps from surviving messages. Micro archives in place under the SAME session id (unlike batch's child-session rotation, NousResearch#57491), so surviving stamps are accurate; stripping them meant an archive_and_compact failure left every previously-persisted message unstamped and the next append-only flush re-inserted them all as duplicate active rows. W5: finalize_turn micro gate now checks agent._persist_disabled — persistence-isolated fork agents (background review) must not burn an aux call per review turn, and must never archive_and_compact the canonical session rows if their compressor ever gains a DB binding. W1: _serialize_one_exchange now delegates to _serialize_for_summary (was a ~70-line near-verbatim copy; one serializer, one place to fix). S4: _find_one_exchange boundary guard rejects only assistant/tool boundaries (the actual alternation hazard) instead of requiring user — a stray mid-list system/injected message can no longer wedge the cursor forever. 5 new regression tests; 38 micro/prune tests, 400 compression-suite tests, 61 finalize/persist tests pass; ruff clean.

> **The Herald Release.** Hermes is the herald of the gods, and this release makes him one in earnest: he **speaks** (real-time conversational voice with streaming TTS, barge-in, on-device wake words, and hands-free control across the CLI, desktop, and every audio-capable gateway platform), he **carries word to other agents** (A2A v1.0), he **announces events to your systems** (signed outbound webhooks), and he **cites his sources** (grounded research with verifiable citations and fact-checking). Around that spine: the desktop app became a platform (artifacts with live preview, a plugin SDK, quick-entry from anywhere, multiple windows), the CLI got a wave of power commands (`!` shell mode, `/init`, `/diff`, `/context`, `/focus`), compression got smarter and gentler, and the tools themselves now recover from their own failures instead of making the model guess. This release rolls up everything from the v0.19.1 infrastructure patch tag — that window is fully documented here.
***
##### ✨ Highlights
- **Talk to Hermes — streaming, conversational voice with barge-in** — Voice mode used to mean: speak, wait for the whole reply to generate, then listen to one long audio file. Now Hermes speaks clause-by-clause as the response streams, you can interrupt it mid-sentence by just talking (it stops, listens, and the model is told you cut in), and busy-aware silence detection means it doesn't talk over you. This works in CLI voice mode, on the desktop, and through gateway adapters. Talking to Hermes finally feels like a conversation, not a voicemail exchange. ([#​69511](https://github.com/NousResearch/hermes-agent/pull/69511), [#​73862](https://github.com/NousResearch/hermes-agent/pull/73862), [#​74223](https://github.com/NousResearch/hermes-agent/pull/74223), [#​74000](https://github.com/NousResearch/hermes-agent/pull/74000), [#​69602](https://github.com/NousResearch/hermes-agent/pull/69602) — [@​teknium1](https://github.com/teknium1), [@​OutThisLife](https://github.com/OutThisLife))
- **Wake words and hands-free control** — Say your own open-vocabulary wake phrase ("hey Hermes", or anything you pick) and Hermes starts listening — detection runs on-device, so no audio leaves your machine while it waits. Multi-profile voice routing means different wake words can reach different profiles, and saying "stop" ends the voice chat on every surface without touching the keyboard. Your terminal is now something you can talk to from across the room. ([#​70509](https://github.com/NousResearch/hermes-agent/pull/70509), [#​73106](https://github.com/NousResearch/hermes-agent/pull/73106), [#​73933](https://github.com/NousResearch/hermes-agent/pull/73933) — [@​teknium1](https://github.com/teknium1))
- **Voice on every platform** — Send a voice note to Hermes on WhatsApp, Feishu, DingTalk, LINE, QQ, Photon, or Weixin and it's transcribed and answered; auto-TTS replies are delivered platform-aware (opus where platforms want opus, captions attached correctly). STT is now fully configurable — its own `hermes tools` category, GUI toggles, dashboard dropdowns, unified language resolution so transcripts stop coming back in the wrong language, and OpenAI's gpt-transcribe support. One unified spoken-text preprocessor cleans markdown, code, and URLs out of speech across all TTS providers. ([#​73515](https://github.com/NousResearch/hermes-agent/pull/73515), [#​73508](https://github.com/NousResearch/hermes-agent/pull/73508), [#​73910](https://github.com/NousResearch/hermes-agent/pull/73910), [#​73513](https://github.com/NousResearch/hermes-agent/pull/73513), [#​73067](https://github.com/NousResearch/hermes-agent/pull/73067) — [@​teknium1](https://github.com/teknium1))
- **Research you can trust — grounded citations with fact-checking** — The new `grounded-citations` skill makes Hermes produce research where every claim is backed by a verifiable source: quotes are matched against the actual page text (not hallucinated), citations link to the exact evidence, and a fact-checking mode turns the same machinery on any document or claim you hand it — it tells you what checks out, what doesn't, and what couldn't be verified. If you use Hermes for research, this is the difference between "sounds right" and "provably sourced." ([#​71698](https://github.com/NousResearch/hermes-agent/pull/71698), [#​77104](https://github.com/NousResearch/hermes-agent/pull/77104) — [@​teknium1](https://github.com/teknium1))
- **Outbound webhooks — Hermes pushes events to your systems** — Until now, integrating with Hermes meant polling or listening on a platform. Now Hermes pushes **signed lifecycle events** (session activity, turn completions, tool events) to any HTTP endpoint you register — with HMAC signatures so your receiver can verify authenticity. Wire Hermes into your CI, your home automation, your dashboards, or any service that speaks HTTP, with no polling loop. ([#​69406](https://github.com/NousResearch/hermes-agent/pull/69406) — [@​teknium1](https://github.com/teknium1))
- **The desktop app becomes a platform — artifacts, plugin SDK, quick entry** — Hermes desktop now renders **artifacts**: versioned cards with sandboxed live preview in a right-rail viewer, so generated HTML/apps run safely next to the chat. A real **plugin SDK** landed with Kanban as its founding plugin, `ctx.download` for handing users files, floating pane placement, and multiple GUI windows. A global-hotkey **quick-entry window** captures a thought into any session from anywhere in your OS. The desktop stopped being a chat client and started being a workbench. ([#​72345](https://github.com/NousResearch/hermes-agent/pull/72345), [#​61173](https://github.com/NousResearch/hermes-agent/pull/61173), [#​74413](https://github.com/NousResearch/hermes-agent/pull/74413), [#​72315](https://github.com/NousResearch/hermes-agent/pull/72315), [#​68259](https://github.com/NousResearch/hermes-agent/pull/68259), [#​73143](https://github.com/NousResearch/hermes-agent/pull/73143) — [@​OutThisLife](https://github.com/OutThisLife), [@​teknium1](https://github.com/teknium1))
- **Hermes speaks Agent-to-Agent — A2A v1.0** — A new bundled plugin implements the Agent-to-Agent protocol, so Hermes can discover, talk to, and be driven by other A2A-compatible agents. This closes issue [#​514](https://github.com/NousResearch/hermes-agent/issues/514) — one of the oldest open feature requests in the repo. If you're building multi-agent systems with heterogeneous stacks, Hermes now has a standard wire protocol for joining them. ([#​77109](https://github.com/NousResearch/hermes-agent/pull/77109) — [@​teknium1](https://github.com/teknium1))
- **CLI power-user wave** — `!command` runs a shell command instantly without spending a model turn. `/init` scans your project and generates (or updates) an `AGENTS.md`. `/diff` shows staged/all/session changes from any surface, `/context` breaks down exactly what's filling your context window, `/focus` gives you a reduced-output view with hidden-line recovery, and Ctrl+S stashes a half-written prompt into a browsable panel. Plus `hermes import-agent` migrates your Claude Code or Codex CLI setup into Hermes in one command. ([#​72257](https://github.com/NousResearch/hermes-agent/pull/72257), [#​72178](https://github.com/NousResearch/hermes-agent/pull/72178), [#​72240](https://github.com/NousResearch/hermes-agent/pull/72240), [#​72242](https://github.com/NousResearch/hermes-agent/pull/72242), [#​72302](https://github.com/NousResearch/hermes-agent/pull/72302), [#​72262](https://github.com/NousResearch/hermes-agent/pull/72262), [#​72190](https://github.com/NousResearch/hermes-agent/pull/72190) — [@​teknium1](https://github.com/teknium1), several salvaging long-standing community PRs)
- **Correct the agent mid-turn — redirects** — If Hermes is heading the wrong way, you no longer have to `/stop` and re-explain. Type a correction while it works and the active turn is redirected: work in flight is preserved, the original prompt is kept, and the agent course-corrects with your new guidance. Paired with double-ESC draft discard and a composer undo stack, steering feels like editing, not restarting. ([#​63104](https://github.com/NousResearch/hermes-agent/pull/63104), [#​72339](https://github.com/NousResearch/hermes-agent/pull/72339), [#​74736](https://github.com/NousResearch/hermes-agent/pull/74736) — [@​OutThisLife](https://github.com/OutThisLife))
- **Tools that fix themselves** — A sweep of self-recovery upgrades means the agent wastes far fewer turns on tool friction: truncated terminal output spills to a file the agent can read back, `patch` detects already-applied edits and diagnoses whitespace mismatches, `write_file` verifies content on disk, searches that match nothing probe for near-misses and recover, and common failure classes come back with actionable hints. The default tool-calling iteration limit also jumped 90 → 500 — long autonomous runs stopped hitting an artificial wall. ([#​77041](https://github.com/NousResearch/hermes-agent/pull/77041), [#​76998](https://github.com/NousResearch/hermes-agent/pull/76998), [#​77024](https://github.com/NousResearch/hermes-agent/pull/77024), [#​77055](https://github.com/NousResearch/hermes-agent/pull/77055), [#​77011](https://github.com/NousResearch/hermes-agent/pull/77011), [#​76992](https://github.com/NousResearch/hermes-agent/pull/76992), [#​72176](https://github.com/NousResearch/hermes-agent/pull/72176) — [@​teknium1](https://github.com/teknium1))
- **Compression that respects your conversation** — Context compression got a deep overhaul: proactive tool-result pruning for large-window models, per-turn micro-compaction that amortizes the cost instead of one giant pause, a guaranteed N-user-message tail so recent conversation always survives, progress-aware timeouts that stop punishing slow summary models, and ghost-skill defense so a pruned skill can never silently haunt a session. Thresholds are now configurable per-model and in absolute tokens. Long sessions stay coherent and stop stalling.

- **Smart approvals grow up** — `hermes approvals suggest` mines your approval history into allowlist proposals, operators can customize the smart-approval policy, a consecutive-denial circuit breaker stops a misbehaving loop cold, and desktop pairing approvals are profile-correct with a proper surface to answer them from. Plus a new approval gate for docker/podman daemon-redirect commands. Less clicking "approve", without giving an inch of control.

Summary
Salvage of #74522 by @lxman: opt-in per-turn micro-compaction — instead of one long stall when the context window fills, each completed turn folds the oldest un-absorbed exchange into a rolling summary, keeping occupancy low and flat. All 11 of @lxman's commits cherry-picked with authorship preserved, plus one follow-up commit fixing two integration bugs found in review.
Off by default (
compression.micro_compact: false) because each pass rewrites already-sent history and breaks the prompt-cache prefix; the PR body, config comments, anddocs/micro-compaction.mdstate that cost plainly.What the follow-up commit fixes
Both bugs were confirmed with empirical probes against the production repair path, not just by reading:
1. Alternation: summary marker destroyed by
repair_message_sequence.The marker was
role="user"and an exchange was a single assistant+tools group, so splicing between two user turns produceduser → marker(user) → user. The pre-request repair pass (runs before EVERY API call) merged the marker into the neighbouring real user message — metadata gone, cursor unrecoverable on resume, summary text duplicated into the transcript on every later pass (the transcript grew each turn).Fix: an exchange is now a full agent turn (assistant + tools + follow-up iterations, bounded by user messages), the marker is assistant-role, and superseding an old marker deliberately merges the two newly-adjacent real user turns (plain-text
\n\n-join, identical to repair pass 2 — no user text is ever lost).Probe: repairs 2 → 0, marker survives, no summary leakage, resume-scan finds the marker.
2. Defrag silently absorbed user messages.
_defrag_rolling_summaryserialized the whole remaining middle (user turns included) and spliced it away — 8 of 10 user prompts destroyed in one pass, contradicting the feature's headline "your messages are never compacted" invariant.Fix: defrag now re-summarizes only the rolling summary text and rewrites the marker content in place; transcript shape, cursor, and user turns untouched.
Probe: 10 of 10 user prompts survive.
Also: marker provenance is now
COMPRESSED_SUMMARY_HAS_USER_TURN_KEY=False(micro markers absorb only assistant/tool content, per the #64650 invariant).Validation

Based on #74522 by @lxman — cherry-picked to preserve authorship (11 commits). The feature design, docs, telemetry, and measurement methodology are his; the follow-up commit only corrects the two integration bugs above.
Depends on #75344 (AUTHOR_MAP entry) landing first.
Closes #74522
