chore(ci): resync dependency lock — multidict 6.7.1 → 6.8.0 (upstream release drift)

Same contract as the platformdirs resync: the lock pins a version that a
fresh resolve no longer produces. Regenerated per check_dep_lock's own
instruction. Pre-existing master drift, gates this PR.

(2) LEXICAL — a SQLite FTS5 virtual table over entities(name, summary) and aliases(alias), inserted as a fallback tier in entity resolution (lines 224-237) with lookup order exact -> alias -> FTS5 BM25 -> substring-LIKE; index maintained on the existing entity/alias write path (resolve_entity, add_edge) in the same DB file.

Never touch `self.messages` — the projection list and ConversationStateRepository remain the durable record; only DOM widgets are bounded. Do NOT rewrite the log on RichLog/Line-API virtual rendering (RichLog's `max_lines` idiom — https://textual.textualize.io/widgets/rich_log/ — proves bounded retention is upstream-sanctioned, but its lines are not interactive widgets): bubbles must stay interactive (ThinkingBubble toggle chat_bubble.py:261-276; ToolCallWidget decision buttons message_widgets.py:14-41).

Valid JSON, no code modified, no stage advanced.\n\n**Headline findings:**\n\n- **Critical (A2) — INN-1's as-of filter is falsified as specified.** Supersede at `graph_memory.py:207-208` sets `status`/`superseded_by` but **never writes `valid_until`** — superseded edges stay NULL-open on the valid axis. The proposed filter (`valid_from <= t AND (valid_until IS NULL OR t < valid_until) AND learned_at <= t`) therefore returns **both sides of every contradiction** as current knowledge. A time-travel query would be wrong on its first contradiction. C5 survives only in corrected form (M1: one-line valid_until-on-supersede fix, or transaction-time-only as-of via `learned_at` + `superseded_by` chain).\n\n- **High (A5) — the production graph is empty.** Read-only inspection of `/mnt/workdrive/rune/memory/graph/graph.sqlite`: 0 entities, 0 aliases, 0 edges. C6's \"capped recall\" benefit is vacuous today; the real bottleneck is write-side adoption (curator's strength<3 gate + fixed verb map at `curator.py:1355-1388`).\n\n- **High (A1/A11) — the \"bi-temporal, implements E14 1:1\" claim is schema-only.** `valid_until` has no writer anywhere in the repo; `status='expired'` is unreachable; `valid_from == learned_at` on every insert. And \"supersede-on-contradiction\" keys on identical triples only — differently-normalized restatements produce parallel active edges with no invalidation. C4 survives **with a downgrade**: downstream dossiers must call it a transaction-time append log with same-triple supersession.\n\n- **High (A6) — duplicate authority for C6.** `memory_store.py` already runs FTS5 BM25 hybrid retrieval (retain-authority, `RECALL_MIN_SCORE=0.42`), and `memory_selector._graphs_recall` re-floors every graph candidate — a typo the new FTS5 tier resolves can still be killed at the selector. INN-1 never mentions the selector. C6 survives conditionally, reframed as a rebuildable projection with an end-to-end selector-level kill test (T3).\n\n- **C9** survives track-only, constrained: any future DuckDB/Arrow sidecar must be a rebuildable read-only projection of `graph.sqlite`, never a second store.\n\nSequencing correction (A13): write-side population first, the valid_until fix second, read-layer work last — INN-1 proposed the read layer first on an empty store. Falsification tests T1–T6 are executable directly from the dossier.","time":{"start":1788954467545,"end":1788954480329}}}

The dossier's own `repo_grounding_note` and Graphiti E17 (temporal semantics at framework layer, decoupled from storage) confirm Rune already occupies that layer.\n\n**Candidates**:\n| ID | Candidate | Classification |\n|---|---|---|\n| C1 | Neo4j backend | CONFLICTS_WITH_RUNE — JVM server, ~5GB RSS (E6), no native temporal versioning (E28-E30) |\n| C2 | FalkorDB backend | CONFLICTS_WITH_RUNE — Redis module/SSPLv1, only embedded path is falkordblite (E16); benchmark advantages are outside Rune's regime |\n| C3 | LadybugDB backend | INSUFFICIENT_EVIDENCE — best *shape* fit (embedded/MIT/FTS/vector, E20) but young revival fork (E24), no Graphiti driver, zero Rune-regime benchmarks |\n| C4 | Graphiti bi-temporal model | DIRECTLY_APPLICABLE — already integrated 1:1 |\n| C5 | NEP-001 \"AS OF\" queries | APPLICABLE_WITH_ADAPTATION — time-travel over history Rune already stores but can't query (`--as-of` filter in `query()`) |\n| C6 | Hybrid retrieval entry | APPLICABLE_WITH_ADAPTATION — FTS5 lexical tier for entity resolution (currently exact/alias/substring only) |\n| C7/C8/C10 | Driver abstraction / Cypher temporal types / LLM ingestion | TOO_COMPLEX_FOR_VALUE |\n| C9 | Ladybug Memory lakehouse stack | PROMISING_FOR_INNOVATION — adjacent-field lead, not coupled to this spike |\n\n**Route: INNOVATION_WARRANTED** — the literal spike question (backend choice) resolves to standard: no swap is warranted. But combining research with Rune's architecture yields two genuinely missing capabilities that no standard drop-in provides: temporal AS-OF queries (C5) and lexical hybrid entry (C6), both staying inside the embedded, no-new-dependency posture.

(4) BM25 ranking quality is evidenced only via Graphiti's claim, not measured at Rune's regime (dossier limitation #7) — hence the kill test below.

High-level identity._\n7: \n8: Rune project research pipeline (repo at `/mnt/workdrive/rune/`). Sessions in this project execute structured research rounds against Gitea issues, one stage at a time, dispatched as headless prompts carrying a process capsule (process_id, issue, round, current_stage, allowed_action_now, expected_completion_artifact).\n9: \n10: ## Rules\n11: _Hard constraints from user that every session must respect._\n12: \n13: - Stage prompts are authoritative: obey `allowed_action_now` strictly (e.g., DEFINE forbids codebase analysis and web research).\n14: - Stage artifacts end with the literal line `StageCompleted: <STAGE>` (or `StageFailed: <STAGE>` + `Reason:`). Never fabricate a stage outcome.\n15: \n16: ## Architecture decisions\n17: _Major design choices with rationale. The \"why\" matters more than the \"what\" for future sessions._\n18: \n19: (none yet)\n20: \n21: ## Discovered durable knowledge\n22: _Cross-task facts that survive across sessions. Promoted from session checkpoints' §7 when proven durable._\n23: \n24: - Rune research pipeline has 8 stages: DEFINE → INWARD → OUTWARD_DISCOVERY → OUTWARD_READING → ADVERSARIAL → INNOVATION → SYNTHESIS (+1 completion/validation stage). Dispatched headless via `.gitea/workflows/research-stage-headless.yml` (PRs #217/#218) + `run_agent_stage.py` (#222).\n25: - Research questions are filed in the Rune repo as `research/issue-<n>-research.md` (or under `/mnt/workdrive/rune/research/<topic>/` subdirectories). DEFINE-stage dispatches may reference \"the research question\" without restating it — locate the question file before classifying.\n26: - Stage-execution tree for research rounds lives at `/mnt/workdrive/research-stage/` (holds src/rune/ + research-executor commits, e.g. HEAD 83ea89c \"OUTWARD_DISCOVERY executor\"); distinct from the subject repo `/mnt/workdrive/rune/`.\n27: - OUTWARD_DISCOVERY technique that works here: plain webfetch of `https://duckduckgo.com/html/?q=<url-encoded query>` returns title+URL+snippet SERPs; batch ≥4 queries in parallel; snippet-level evidence satisfies the \"discover URLs, classify sources, don't read full sources\" stage contract.\n28: - OUTWARD_READING technique that works here: batch webfetch in parallel; GitHub repos read cleaner via `raw.githubusercontent.com/<owner>/<repo>/<branch>/README.md` (avoids page chrome); dev.to and sqliteforum.com (Substack-style) pages fetch OK but carry navigation noise around mid-page content; extracted claims go in a session spillover file (e.g. `checkpoint-outward-reading-sources.md`) with S-numbered source IDs so the ADVERSARIAL stage can reference claims.\n29: - Rune's SQLite usage (grounding for DB-related research questions): ~15 modules in src/rune/ each open fresh short-lived sqlite3 connections per call against a shared STORE_DB (mix of RW and `file:...?mode=ro` URI reads) across multiple OS processes; only task_gate.py sets `PRAGMA journal_mode=WAL` explicitly; sqlite-vec extension must be loaded per connection (issue #26 defect fix).\n30: - Newer pipeline runs use a 7-stage pipeline with a UNIFIED OUTWARD stage (discovery + reading merged, O-numbered source IDs, artifact ends `StageCompleted: OUTWARD`); the older 8-stage split (OUTWARD_DISCOVERY → OUTWARD_READING, S-numbered IDs) still applies to older rounds like issue-262. Deterministic DEFINE contracts may mark sub-stages \"skipped\" while the unified stage still requires \"≥2 unique URLs\".\n31: - Stage-state source of truth per round is on disk at `/mnt/workdrive/research-stage/research/issue-<n>/task_tree.json` (artifacts per stage, stage_history, expected_artifact like synthesis.json); run directories live alongside under `research/issue-<n>/runs/`.\n32: - Rune's memory stack (grounding for issue-161 OUTWARD): sqlite-vec (dense vectors) + FTS5 (BM25) in one SQLite file (`src/rune/memory_store.py`), hybrid recall accelerated by a precomputed association graph (hops=1); separate headless SQLite graph tier at `memory/graph/graph.sqlite` (`src/rune/graph_memory.py`); no Qdrant dependency exists — the \"vs Qdrant vs graph backends\" part of the question is comparative Line truncated

My work at Kuzu was all about helping users figure out how to transform and query their data as a graph, experimenting with how to define graph data models and relationships for different domains, how to bring the power of Cypher to developers who didn’t want to spin up a server or pay for a proprietary tool just to run traversal queries.\n\nIn September 2025, Kuzu got archived, and the codebase went quiet. But the ideas were still relevant. The graph community still highly valued a permissively licensed, embedded graph storage and query engine that supported Cypher.\n\nThat’s where LadybugDB comes in. It’s a fork of Kuzu, maintained by the team at [Ladybug Memory ⤴](https://ladybugmem.ai/), but with a slightly different goal. Kuzu was built primarily as a standalone, embedded graph database. Ladybug wants to be a **graph lakehouse** — interoperating with DuckDB’s storage layer, reading and writing Arrow/Parquet, connecting to object stores. The same columnar foundation, but opened up to the broader ecosystem.\n\nOver the past few months, I’ve been in close discussions with [Arun Sharma ⤴](https://x.com/arundsharma), lead maintainer of LadybugDB. Having explored what his vision looks like in practice, I wanted to share a small project that demonstrates at least a part of the Ladybug’s vision: running fast graph algorithms natively on top of columnar graph storage.\n\nTowards the end of this post, we’ll lead into the bigger picture and what this all means for folks working with graphs.\n\nNote on the nomenclature\n\nLadybugDB refers to the database itself, while [Ladybug Memory ⤴](https://ladybugmem.ai/) refers to the collection of projects that are building towards graph-based continual learning for agents. When I say “Ladybug” in this post, I’m referring to the database.\n\n## Dataset: Who Mentored the Most Nobel Laureates?[#](#dataset-who-mentored-the-most-nobel-laureates)\n\nThe dataset we’ll be working with (see [the repo ⤴](https://github.com/prrao87/ladybug-intro) if you want to follow along) is a mentorship network of Nobel laureates, containing thousands of records that trace the academic lineages of prize winners across Physics, Chemistry, and Medicine.\n\nIt turns out that research has shown Nobel Prize committees don’t just reward isolated genius. They reward people who are already in the right networks, having received mentorship from the right teachers, who were part of the *just the right* intellectual institutions. This makes sense when you learn from the data that Niels Bohr mentored *ten* Nobel laureates in Physics. Or that J.J. Thomson, discoverer of the electron, mentored *eleven*? These aren’t just names on a list — they’re nodes in a network of knowledge transmission that spans more than a century.\n\nThe data comes in JSON format, structured as parent-child relationships. Each record has a “child” (the mentee) and one or two “parents” (the mentors). Some of those children are laureates with prize categories and years attached. Others are scholars — people who never won a Nobel but who mentored someone who did, or who mentored someone who mentored someone who did.\n\nThis data is naturally analyzed as a graph. You could flatten it into a table and run SQL queries with traditional joins, but you’d lose its inherenLine truncated

Star this repo!*\n\n&nbsp;\n\nGraphiti is a framework for building and querying temporal context graphs for AI agents. Unlike static knowledge graphs,\nGraphiti's context graphs track how facts change over time, maintain provenance to source data, and support both\nprescribed and learned ontology — making them purpose-built for agents operating on evolving, real-world data.\n\nUnlike traditional retrieval-augmented generation (RAG) methods, Graphiti continuously integrates user interactions,\nstructured and unstructured enterprise data, and external information into a coherent, queryable graph. The framework\nsupports incremental data updates, efficient retrieval, and precise historical queries without requiring complete graph\nrecomputation, making it suitable for developing interactive, context-aware AI applications.\n\nUse Graphiti to:\n\n- Build temporal knowledge graphs that evolve with every interaction — tracking what's true now and what was true before.\n- Represent rich, structured context instead of flat document chunks or raw event streams.\n- Query across time, meaning, and relationships with hybrid retrieval (semantic + keyword + graph traversal).\n\n&nbsp;\n\n<p align=\"center\">\n    <img src=\"images/graphiti-graph-intro.gif\" alt=\"Graphiti temporal walkthrough\" width=\"700px\">\n</p>\n\n&nbsp;\n\n## What is a Context Graph?\n\nA **context graph** is a temporal graph of entities, relationships, and facts — like *\"Kendra loves Adidas shoes (as of\nMarch 2026).\"* Unlike traditional knowledge graphs, each fact in a context graph has a validity window: when it became\ntrue, and when (if ever) it was superseded. Entities evolve over time with updated summaries. Everything traces back to\n**episodes** — the raw data that produced it.\n\nWhat makes Graphiti unique is its ability to autonomously build context graphs from unstructured and structured data,\nhandling changing relationships while preserving full temporal history.\n\nA context graph contains:\n\n| Component | What it stores |\n|-----------|---------------|\n| **Entities** (nodes) | People, products, policies, concepts — with summaries that evolve over time |\n| **Facts / Relationships** (edges) | Triplets (Entity → Relationship → Entity) with temporal validity windows |\n| **Episodes** (provenance) | Raw data as ingested — the ground truth stream. Every derived fact traces back here |\n| **Custom Types** (ontology) | Developer-defined entity and edge types via Pydantic models |\n\n## Graphiti and Zep\n\nGraphiti is the open-source framework for building temporal knowledge graphs at the core of\n[Zep's](https://www.getzep.com) context infrastructure. Zep manages context graphs at scale, providing\ngoverned, low-latency context retrieval and assembly for production deployments.\n\nUnder the hood, Line truncated

Two time dimensions are made first-class: **valid time** (when a fact was\ntrue in the world) and **transaction time** (when it was recorded in the database).\nThe proposed syntax is:\n\n```cypher\nMATCH (w:Well)-[r:OWNED_BY]->(c:Company)\nAS OF date('2024-06-15')\nRETURN w.name, c.name\n```\n\nThis proposal is motivated by production experience with 3.1M+ temporally-annotated\nrelationships across a complex regulatory and operational graph. Every temporal query\nin that system is today expressed with verbose manual filtering that is fragile,\nhard to optimise, and easy to get wrong. Native support would eliminate that entire\ncategory of application complexity.\n\n---\n\n## 1. Motivation\n\n### 1.1 The Temporal Graph is Universal\n\nNearly every domain that benefits from a graph database also has temporal semantics:\n\n| Domain | Temporal fact |\n|--------|--------------|\n| Corporate ownership | \"Who owned this asset between 2018 and 2022?\" |\n| Regulatory compliance | \"What rules applied to this facility in Q3 2024?\" |\n| Supply chain | \"Which supplier was contracted at the time of this incident?\" |\n| Org charts | \"Who was this person's manager on the date the decision was made?\" |\n| Medical records | \"What medications was the patient on at admission?\" |\n| Financial | \"What was the firm's capital structure at close on this date?\" |\n\nIn every case, the graph has the right structure for the query — the challenge is\npurely about time. Relationships change: they are created, modified, and ended.\nThe naive graph models a snapshot of the present. What users need is access to\nthe full temporal history.\n\n### 1.2 The Current State Is Broken\n\nToday, teams work around missing native temporal support by storing `valid_from`\nand `valid_to` (or `effective_date` / `end_date`) directly on relationship\nproperties. This works, but it has serious problems.\n\n**The query pattern is verbose and error-prone:**\n\n```cypher\n-- \"Who owned this well on June 15, 2024?\"\n-- Current approach — every developer writes this differently\nMATCH (w:Well {wellId: $id})-[r:OWNED_BY]->(c:Company)\nWHERE (r.effective_date IS NULL OR r.effective_date <= date('2024-06-15'))\n  AND (r.end_date IS NULL OR r.end_date >= date('2024-06-15'))\nRETURN c.name\n```\n\nCommon mistakes include: forgetting to handle `NULL` as \"open-ended\", using `<`\ninstead of `<=`, inconsistent property naming across relationship types, incorrect\nhandling of the half-open interval `[effective_date, end_date)`, and failing to\naccount for relationships that predate any recorded `effective_date`.\n\n**It doesn't compose:**\n\n```cypher\n-- \"Trace ownership and regulatory authority as of a given date\"\n-- Current: every hop needs its own temporal filter, duplicated everywhere\nMATCH (w:Well {wellId: $id})\n      -[r1:OWNED_BY]->(c:Company)\n      -[r2:SUBJECT_TO]->(a:Authority)\nWHERE (r1.effective_date IS NULL OR r1.effective_date <= $asOf)\n  AND (r1.end_date IS NULL OR r1.end_date >= $asOf)\n  AND (r2.effective_date IS NULL OR r2.effective_date <= $asOf)\n  AND (r2.end_date IS NULL OR r2.end_date >= $asOf)\nRETURN c.name, a.name\n```\n\nAs path depth increases, the WHERE clause grows linearly. At depth 4 or 5 (common\nin regulatory traversals), the query becomes unmaintainable.\n\n**It cannot be optimised:**\n\nThe planner has no way to know that `r.effective_date <= date('2024-06-15')` is\na temporal filter — it looks like any other property predicate. A native temporal\nlayer would allow the planner to choose appropriate physical operators (temporal\nindex scans, period overlap joins) that are fundamentally more efficient.\n\n**It has no transaction time:**\n\nThe property-based approach stores only valid time (when something was true in the\nworld). Transaction time (when the database recorded it) is lost unless the\napplication explicitly adds an `_recorded_at` property to every write. Recovering\n\"what did the database know at 9am on this date\" is impossible without this.\n\n### 1.3 Evidence from Production\n\nThe following numbers come from a production Neo4Line truncated

This section will discuss how Cypher handles time zones, before exploring temporal values in more detail.\n\n|  | Refer to [Temporal functions - instant types](https://neo4j.com/docs/cypher-manual/current/functions/temporal/) for information regarding temporal _functions_ allowing for the creation and manipulation of temporal values. Refer to [Temporal operators](https://neo4j.com/docs/cypher-manual/current/expressions/temporal-operators/) for information regarding temporal _operators_. Refer to [Equality, ordering, and comparison of value types](https://neo4j.com/docs/cypher-manual/current/values-and-types/ordering-equality-comparison/) for information regarding the comparison and ordering of temporal values. |\n|  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n## [](#%5Ftemporal%5Fvalue%5Ftypes)Temporal value types\n\nThe following table lists the temporal value types and their supported components:\n\n| Type           | Date support | Time support | Time zone support |\n| -------------- | ------------ | ------------ | ----------------- |\n| DATE           |              |              |                   |\n| LOCAL TIME     |              |              |                   |\n| ZONED TIME     |              |              |                   |\n| LOCAL DATETIME |              |              |                   |\n| ZONED DATETIME |              |              |                   |\n| DURATION       | \\-           | \\-           | \\-                |\n\n`DATE`, `LOCAL TIME`, `ZONED TIME`, `LOCAL DATETIME`, and `ZONED DATETIME` are _temporal instant_ types. A temporal instant value expresses a point in time with varying degrees of precision.\n\nBy contrast, `DURATION` is not a temporal instant type. A `DURATION` represents a temporal amount, capturing the difference in time between two instants, and can be negative. `DURATION` captures the amount of time between two instants, it does not capture a start time and end time.\n\n## [](#cypher-temporal-timezones)Time zones\n\nTime zones are represented either as an offset from UTC, or as a logical identifier of a _named time zone_ (these are based on the [IANA time zone database](https://www.iana.org/time-zones)). In either case, the time is stored as UTC internally, and the time zone offset is only applied when the time is presented. This means that temporal instants can be ordered without taking time zone into account. If, however, two times are identical in UTC, then they are ordered by timezone.\n\nWhen creating a time using a named time zone, the offset from UTC is computed from the rules in the time zone database to create a time instant in UTC, and to ensure the named time zone is a valid one.\n\nIt is possible for time zone rules to change in the IANA time zone database. For example, there could be alterations to the rules for daylight savings time in a certain area. If this occurs after the creation of a temporal instant, the presented time could differ from the originally-entered time, insofar as the local timezone is concerned. However, the absolute time in UTC would remain the same.\n\nThere are three ways oLine truncated

O5 README unretrievable, no FalkorDB-native temporal docs read, Apple-acquisition claim single-sourced), 4 contradictions (benchmark magnitudes by sponsor, Kuzu closure cause, \"production-tested RedisGraph\" framing, embedded-path-via-Graphiti gap), and a repo grounding note tying evidence to `src/rune/graph_memory.py`'s embedded SQLite posture.\n\nStopped per stage rules — evidence requirement (≥2 unique URLs) exceeded; no synthesis, no design, no code changes.\n\nStageCompleted: OUTWARD","time":{"start":1788951154576,"end":1788951167283}}}

INN-1's original formulation was falsified twice over: its as-of filter returns BOTH sides of a contradiction as current knowledge against the current writer (A2, critical — supersede never writes valid_until, graph_memory.py:207-208), and its benefit chain is broken at the empty graph (A5) and again at the memory_selector floor (A6). The adversarial stage's simpler-alternative analysis (A3, A13) dictated the winning shape: fix the writer first (one line, free backfill on an empty DB), then read-layer work, measured end-to-end. Within M1, option (a) wins over option (b): the valid_until-on-supersede fix makes the documented bitemporal filter correct with a single WHERE clause and avoids inventing a superseded_by chain-walk helper with terminal/cycle semantics (CA6); option (b) is retained as a documented fallback should T2 falsify M1a. C4 and C9 survive as constraints, not work: C4's 'bi-temporal E14 1:1' claim is contradicted by the code (A1, A11) and survives only as a corrected characterization (M6); C9 is track-only (A9/A10) and contributes only the M7 boundary on future analytics.

But INN-1's original synthesis was falsified twice over: its as-of filter returns BOTH sides of a contradiction as current knowledge against the current writer (A2, critical — supersede never writes valid_until, graph_memory.py:207-208), and its benefit chain is broken at the empty graph (A5) and again at the memory_selector floor (A6).

Within M1, option (a) wins over option (b): the valid_until-on-supersede fix makes the documented bitemporal filter correct with a single WHERE clause and avoids inventing a superseded_by chain-walk helper with terminal/cycle semantics (CA6); option (b) is retained as a documented fallback should T2 falsify M1a. C4 and C9 survive as constraints, not work: C4's 'bi-temporal E14 1:1' claim is contradicted by the code (A1, A11) and survives only as a corrected characterization (M6); C9 is track-only (A9/A10) and contributes only the M7 boundary on future analytics.

+"""stage_telemetry.py — StageAttempt telemetry (OBS-1, epic #284 / #287).
+
+OBSERVATIONAL ONLY. This module records what happened; it must never change
+stage authorization, retry behavior, model prompts, runner selection, or gate
+outcomes. Timing code is not a process authority.
+
+Design decisions (ratified in #287 tightening):
+- EVERY attempt persists its own lifecycle record — successful, gate-failed,
+  failed, timed-out, interrupted. Dropping expensive failures would bias
+  ADAPT-1's baseline toward cheap success.
+- Timing categories are OBSERVED, not forced additive: wall_time is not
+  model_time + tool_time when MiMo waits on a tool or relay overhead overlaps.
+  Records carry the raw timestamps so reports can distinguish exclusive /
+  overlapping / unmeasured-residual.
+- Records survive restart: each attempt is appended to
+  <artifact_dir>/telemetry/attempts.jsonl (append-only, one JSON object per
+  line) AND mirrored into the task-tree state at persist time.
+- UNKNOWN_NOT_EXPOSED is recorded verbatim when a counter (e.g. provider
+  tokens) is unavailable. Estimates are never presented as measurements.
+
+Attempt lifecycle (from the executor's perspective):
+  begin(attempt_id, event_id, stage)  → returns a handle
+  handle.mark_model_start/end()       → model invocation windows
+  handle.mark_tool_start/end()        → tool execution windows
