+//
+// WHAT IT DOES: every actor spawn/run whose brief describes BUILD work must
+// carry the scaffolding admission requirement (mint the construction
+// contract via the admit script before building) AND name a target surface
+// (a repo path or project name). Research-only waves must carry an explicit

+//
+// WHY THE TIGHTENING (adversarial-escape audit, Door 5, HIGH):
+//   * the old pass was purely lexical — a brief containing one marker word
+//     ("scaffolding") satisfied admission for ANY brief;
+//   * the research exemption was self-declared, so a build brief that
+//     mentioned research artifacts passed freely;
+//   * the guard itself was unversioned — no canonical copy, absent from
+//     install_mimo_hook.py MANAGED, drift-undetected: the exact rot that
+//     killed builder-bridge pre-T22.
+//
+// CONVENTION (docs/factory/order-of-things.md §wave-brief compliance law):
+//   (1) SCAFFOLDING ADMISSION — "mint the construction contract" / "admit"
+//       / "scaffolding" in the brief's build instructions;
+//   (2) TARGET SURFACE — a repo path (contains a slash) or a known project

+2. **Orchestration cluster** (commit bded63cf) — 14 sites in 6 files:

+- **Stale kernel .so artifacts (fixed during wave)**: capability_fit,
+  context_pressure, behaviour_ledger target/release .so files lacked
+  symbols their python facades import (cf_free_string,
+  cpx_estimate_tokens, bl_define) — 28 pre-existing reds at HEAD.
+  Rebuilt via cargo; facade owners should add a build-freshness check.
+- **Kernel/oracle divergence (recorded, unfixed)**:
+  structural_store.save_segments' kernel path raises RuntimeError
+  (mkdir envelope) where the python oracle raises OSError — unlike
+  save(), which translates at structural_store.py:153. Test now pins
+  both; the facade should translate for contract parity.
+- **Import-order fragility (systemic)**: 228 tests/test_*.py files lack
+  a sys.path src header and only import `rune` if another module
+  imported first; standalone file runs fail with ModuleNotFoundError.
+  Fixed in 6 files this wave; rest verified via PYTHONPATH=src.
+- **test_scaffold::TestDrift::test_reconcile_marks_stale_authority**
+  fails at HEAD under both cores (STALE expected, CURRENT observed) —
+  authority-behavior drift, NOT converted (not panic-only); owner
+  decision needed (test expectation vs reconcile law).

+## Door-by-door table
+
+| # | Door | Guard | Gap | Severity |
+|---|------|-------|-----|----------|
+| 1 | Conversational turn boundary (`experimental.chat.messages.transform` → `begin`) | Intent classifier mints/resumes contract from the user turn (construction_intent.py:264). Live log shows `begin: mode=EXISTING_PROJECT_CHANGE activated=true`. | `INTERNAL_ENVELOPE` (scaffolding-guard.ts:204) skips classification for ANY user-role text starting with `<`, `[inbox`, `[Never-Ask]` — cron/scheduled-task prompts and actor-notification-shaped build instructions mint NO contract. | HIGH |
+| 2 | Per-call file-tool enforcement (`tool.execute.before` on write/edit/patch/notebook) | Scope check against active contract; fail-closed on bridge failure (in-process + durable lock, scaffolding-guard.ts:314–341). Log shows live `OUT_OF_SCOPE` block. | Only bites when a contract is ACTIVE. NO_CONTRACT mutations are allowed by design (construction_authority.py:855) — the local-edit allowance. Promotion backstop fires only at ≥3 paths AND ≥2 areas (should_promote, :1753), so ≤2 files in 1 area are permanently ungoverned. | MEDIUM (deliberate design) |
+| 3 | Shell / script door (`bash` with interpreters) | Two scans (reference + operand-position targets, :376–621) + lazy postcondition delta at the NEXT mutating call (:100–166). `python -c`, redirects, `--output` flags covered. | (a) Encoded payloads (`python -c "import base64;..."`) carry no path tokens → zero paths → allowed at check time; detection deferred to the lazy checkpoint. (b) The checkpoint is lazy — an escape that is never followed by another mutating call is never reconciled. | MEDIUM |
+| 4 | Git door (commit without contract) | pre-commit = `check_landing.py --staged-only`: banned path + 20MB blob + build rule ONLY (githooks/pre-commit:18). NO contract check. | Worse than "no contract needed": `git add -A && git commit` yields NO resolvable mutation paths (git verbs are not write-operand verbs, `.git` is toolchain-excluded), and check_mutation's remediation exit (:911) treats `not rel_now` as remediation — so a pathless commit is ALLOWED even while a recorded scope violation is unresolved. Escape-then-commit lands mechanically. | HIGH |
+| 5 | Subagent spawn door (actor launches) | subagent-protocol-guard refuses build-shaped briefs lacking admission markers (guard:82–97). | (a) Lexical only: a brief containing one marker word ("scaffolding") passes; nothing verifies admission actually happened. (b) The research exemption is self-declared lexically — a build brief saying "research artifacts to research/" passes freely. (c) The hook is NOT in `install_mimo_hook.py` MANAGED and has NO canonical copy in `config/mimo-hooks/` — unversioned, drift-undetected: the exact rot that killed builder-bridge pre-T22. | HIGH |
+| 6 | Consent→task→dispatch (consent card y → task queue → actor) | The enqueued brief passes through the same spawn guard (Door 5). | Consent approval is not mechanically linked to contract minting: "y" only enqueues; the downstream guarantee is still the lexical marker match, and the actor's own turn-boundary classification sees the brief — but an envelope-prefixed brief hits Door 1's blind spot instead. | MEDIUM |
+| 7 | Promotion backstop (G6) | Ungoverned activity is recorded; at 3 paths/2 areas the contract is minted BEFORE further mutation (:816–854). | Below threshold: ungoverned by design. A deliberate escape can stay at 2 files forever. | LOW (intentional) |
+| 8 | Supervisory self-certification (completion/amend via shell) | `_supervisory_act` refuses complete/amend/declare through the shell during a governed build (:634–653, measured false-positive hardened). | Narrow, well-guarded; residual is the remediation-exit misuse in Door 4. | LOW |
+
+## Synthesis — which gaps matter
+
+The machinery-first stack is real: the conversational path (turn → contract →
+per-call scope → fail-closed) is enforced and evidenced in live logs, and the
+bridge-failure degradation is genuinely fail-closed. The escapes are NOT in
+the conversational path; they are in the paths that BYPASS classification:
+
+1. **The git door is the load-bearing failure.** A commit needs no contract,
+   and the one detection that should catch an escape (unresolved-violation
+   stop) is defeated by the remediation exit's `not rel_now` branch for any
+   pathless command. Everything else can be escaped *into* a commit.
+2. **The spawn guard is law-shaped, not machinery-shaped.** Marker words are
+   trivially satisfiable by the model composing the brief, the research
+   exemption is self-certified, and the guard itself is unversioned —
+   governance enforced by a file nothing hashes or drift-checks.
+3. **The turn-boundary envelope blind spot** means any build instruction that
+   arrives envelope-shaped (cron, scheduled task, notification-styled) is
+   never classified — and with no contract, Door 2 allows everything until
+   promotion. This is the consent→dispatch seam's weakest link.
+
+Theoretical / accepted-by-design: encoded shell payloads (bounded by the lazy
+checkpoint + promotion), sub-threshold local edits (explicit §13 allowance),
+supervisory-act bypass (well-hardened).
+
+## Ranked repairs (machinery, not law)
+
+1. **Contract-aware pre-commit** — add rule 5 to `check_landing.py
+   --staged-only`: refuse the commit when `store/authority-lock.json` is
+   ACTIVE or an unresolved `scope_violation` exists, unless the message names
+   the contract id. Wire is already in `githooks/pre-commit`.
+2. **Close the pathless remediation exit** — in `check_mutation`, grant the
+   remediation allow for `not rel_now` ONLY when `_supervisory_act(command)`
+   resolves the authority-CLI `resolve` op; every other pathless command gets
+   the ordinary NO_CONTRACT/record path.
+3. **Version the spawn guard** — copy `subagent-protocol-guard.ts` to
+   `config/mimo-hooks/`, add to `install_mimo_hook.py` MANAGED, run
+   `--check` in a session-start hook. Mechanical, same contract as
+   scaffolding-guard.
+4. **Strip-then-classify envelopes** — in the turn boundary, remove a leading
+   envelope tag and classify the REMAINDER (record origin="envelope"); never
+   skip classification on shape alone.
+5. **Verify admission mechanically at spawn** — the guard requires the brief
+   to name a contract/wave slug, then calls
+   `construction_authority_cli.py status` and cancels the spawn unless the
+   store shows that admission; replaces word-matching with a store lookup.
+6. **Registry-checked research exemption** — pass a "research-only" brief
+   only if its declared `research/<slug>` exists in the research registry
+   (check_research_gate.py already knows the slugs).
+
+## Honest boundary
+
+This audit is static analysis + log evidence. The encoded-payload shell gap
+(Door 3a) and the envelope blind spot (Door 1) were derived from code, not
+demonstrated live; Doors 2, 4, 5 are mechanically derivable from the code
+paths cited. No code was changed; the only write is this file.

The innovation gate condition (a) in applicability.json is effectively already half-triggered: the 4-method adapter cannot express Rune's abstention semantics without distortion — but the resolution (use the existing registry) is simplification, not invention."

We present a controlled harness evaluation of memory substrates for memory-augmented agents, covering dense and sparse indices, text records, structural stores, hierarchical stores, refinement-based memories, parametric updates, and activation-compatible context mechanisms. Across three backbone models and four benchmark suites spanning user-centric question answering and agent-centric decision-making, we instrument 26 performance and efficiency metrics under a unified harness. Our results show that no single substrate consistently dominates: broad retrieval benefits long-context factual QA, while excessive retrieval can harm sequential decision-making by shifting attention away from action-critical context. Scalability introduces a further routing axis, as substrates that perform well at moderate history lengths can become costly or brittle at longer horizons. These findings motivate substrate routing as a necessary component of adaptive agent memory systems and provide empirical guidance for designing efficient, reliable, and regime-aware long-term memory for LLM agents. Code will be made available upon acceptance.\n    \n\n    \n    \n      \n          Subjects:\n          \n            Computation and Language (cs.CL)\n        \n          Cite as:\n          arXiv:2608.15008 [cs.CL]\n        \n        \n          &nbsp;\n          (or \n              arXiv:2608.15008v1 [cs.CL] for this version)\n          \n        \n        \n          &nbsp;\n                        https://doi.org/10.48550/arXiv.2608.15008\n              \n                \n                Focus to learn more\n              \n              \n              \n                                  arXiv-issued DOI via DataCite\n            \n          \n        \n    \n  \n\n    \n      Submission history From: Wei-Chieh Huang [view email]          [v1]\n        Sat, 15 Aug 2026 03:29:48 UTC (2,271 KB)\n\n  \n  \n    \n      \n      Full-text links:\n      Access Paper:\n      \n  \nView a PDF of the paper titled Harness the Memory: A Holistic Evaluation of Memory Substrates in Memory Agents, by Wei-Chieh Huang and 14 other authorsView PDFHTML (experimental)TeX Source\n \n      view license\n    \n        \n    Current browse context:\n  cs.CL\n\n  \n\n      &lt;&nbsp;prev\n    \n    &nbsp; | &nbsp;    \n      next&nbsp;&gt;\n    \n  \n    new\n     | \n    recent\n     | 2026-08\n  \n    Change to browse by:\n    \n        cs\n    \n  \n\n    \n      \n        References &amp; Citations\n        \n          NASA ADSGoogle Scholar\n          Semantic Scholar\n        \n        \n      \n\n\n    export BibTeX citation\n    Loading...\n\n\n\n    \n        \n            BibTeX formatted citation\n            &times;\n        \n        \n            loading...\n        \n        \n            Data provided by: \n            \n        \n    \n\n  Bookmark\n    \n  \n  \n    \n  \n  \n  \n\n\n  \n    Bibliographic Tools\n    \n      Bibliographic and Citation Tools\n      \n        \n          \n            \n              \n              \n              Bibliographic Explorer Toggle\n            \n          \n          \n            Bibliographic Explorer (What is the Line truncated

No code modified, no stage advanced.\n\n**Verdict: route holds, but the leading candidates needed real breaking.**\n\n**Rejected (1):** `memory-adapter-protocol` — duplicate authority. `memory_selector.py:504-511` already *is* the backend abstraction (the `DEFAULT_SOURCES` registry accepts any `(query, types, budget, min_score)` callable via `add_source`), and the authority map names `ContextBroker.memory_selector` the v1_owner. O12's parallel 4-method protocol would create a second source of truth in a domain that was just consolidated. Its *intent* survives through the existing registry.\n\n**Key attacks that survived against the survivors:**\n- **A1 (high)**: Rune's \"hybrid\" is only hybrid when a live Ollama server is reachable — `_embed` shells out via `curl`, and `recall()` silently degrades to lexical-only mode with no mode field in its output. The harness could validate the wrong system without knowing.\n- **A2 (high)**: `relevance` is a composite (RRF × confidence × temperature × wall-clock recency), so end-to-end nDCG@10 doesn't measure the backend — cross-backend rows would be confounded and unreproducible.\n- **A3 (high)**: the dense gate runs full-table `LIKE` COUNT scans per candidate row per word — latency blow-up far below the 100K–1M regime the issue targets.\n- **A9 (high)**: \"bit-identical reproducibility is discipline, not machinery\" is false here — frozen clock, neutral metadata, and digest-pinned embeddings are all required.\n- **A14 (high)**: none of the source metric suites handle abstention; Recall@k would punish Rune's true-abstention policy as if it were failure.\n- **A10/A11**: external receipts — arXiv 2608.15008's abstract confirms O15's qualitative claims but contains none of E20–E22's numbers; O12 is a 0-star vendor-adjacent repo whose LongMemEval-S numbers sit at 96–99% R@10 (near ceiling, little discriminative power).\n\n**Adjudication**: STANDARD_SOLUTION_SUFFICIENT is not overturned — every attack is about *how* the harness must be built (mode observability, neutralized metadata, abstention-aware metrics, isolated stores, stage-level profiling), not *whether*. Notably, the applicability dossier's innovation-gate condition (a) is effectively half-triggered already: the 4-method adapter genuinely cannot express Rune's abstention semantics — but the resolution is to use the existing registry, which is simplification, not invention.","time":{"start":1788911125724,"end":1788911133821}}}

No code modified, no research re-run.\n\n**How I grounded it:** The INWARD claims were only file-level pointers, so I verified Rune's actual architecture directly: `memory_store.py` (FTS5+sqlite-vec RRF hybrid, abstention floor 0.42, RRF_K=15), `graph_memory.py` (concept-mediated bi-temporal KG in headless SQLite), `memory_selector.py` as the single selection authority, and `orchestration/benchmark.py` (latency-only regression harness — **no retrieval-quality metrics exist in the repo**). Checked `config/v1_authority_map.json` for the `memory_selection` domain ownership.\n\n**9 candidates classified:**\n\n| Candidate | Classification |\n|---|---|\n| sqlite-hybrid-retrieval (O4) | DIRECTLY_APPLICABLE — already Rune's architecture; validation target |\n| memory-adapter-protocol (O12) | APPLICABLE_WITH_ADAPTATION — backend abstraction under the selector |\n| retrieval-quality-metrics-suite (O4/O12) | DIRECTLY_APPLICABLE — fills the repo's real gap |\n| reproducibility-contract (O12) | DIRECTLY_APPLICABLE — fits existing hash-chain/audit culture |\n| matched-precision methodology (O2) | DIRECTLY_APPLICABLE — prevents incomparable-number decisions |\n| qdrant-production-backend (O2/O4) | TOO_COMPLEX_FOR_VALUE — regime mismatch, no service infra, unproven gain at Rune's scale |\n| candidate-pool-vs-ranking diagnostic (O12) | APPLICABLE_WITH_ADAPTATION — extends existing below-floor instrumentation |\n| substrate-family eval of Rune's own tiers (O15) | APPLICABLE_WITH_ADAPTATION — E20 implies no substrate can be adopted on authority |\n| faiss/weaviate adapter rows (O4) | INSUFFICIENT_EVIDENCE — result rows unpublished (E10) |\n\n**ROUTE: `STANDARD_SOLUTION_SUFFICIENT`** — O12's adapter-protocol harness solves the \"abstraction\" half and O4/O2's metrics and matched-precision rules solve the \"harness\" half. The dossier's gaps (100K–1M regime unmeasured, asyncio harness, graph evidence) are all closable by *building the standard harness*, not by inventing anything. The notes record an explicit innovation gate: conditions under which a later INNOVATION pass could be warranted (adapter can't express the graph tier or abstention floor, unstable crossover at Rune's scale, or a novel ranking mechanism emerging from the diagnostic probe).","time":{"start":1788910043355,"end":1788910052601}}}

our summary here, or open the publisher PDF on the next tab.\n\nExplainerOriginal PDF\n\nTHE PROBLEM\n\n## Memory agents lack regime-aware substrate routing: 62% of systems use only LoCoMo and LongMemEval\n\nExisting memory agents mostly evaluate on **LoCoMo** and **LongMemEval**, with 62% of benchmark–system pairs concentrated on these two dialogue-centric datasets.\n\nThis leaves agent-centric tasks and efficiency dimensions underexplored, so long-horizon agents cannot tell which **memory substrate** to use under different operating regimes.\n\nHOW IT WORKS\n\n## Unified Evaluation Harness for Memory Substrates\n\nHarness the Memory builds a **Unified Evaluation Harness** that swaps **External Memory Substrate Families** and **Internal Memory Substrate Families** while keeping backbones, prompts, and auxiliary LLM fixed.\n\nThink of it like a standardized motherboard where different **memory modules**—vectors, graphs, hierarchies, refinements, weights, activations—can be plugged in and stress-tested under identical workloads.\n\nThis harness lets Harness the Memory expose when substrate choices flip across regimes, revealing retrieval-depth failures and scalability limits that a plain context window or single memory design cannot capture.\n\nDIAGRAM\n\n## Interaction Flow Between User, Agent, and Memory Substrates\n\nThis diagram shows how Harness the Memory routes user queries through agents and different memory substrates during evaluation.\n\nDIAGRAM\n\n## Evaluation Pipeline Across Benchmarks and Metrics\n\nThis diagram shows how Harness the Memory evaluates substrates across four benchmarks, three backbones, and 26 metrics.\n\nPROCESS\n\n## How Harness the Memory Handles a Benchmark Run\n\n1.  01\n    \n    Unified Evaluation Harness Setup\n    \n    Harness the Memory first configures the **Unified Evaluation Harness** with fixed prompts, auxiliary GPT-4O-MINI, and vLLM inference across chosen backbones.\n    \n2.  02\n    \n    Memory Substrate Configuration\n    \n    Harness the Memory then selects one of the **External Memory Substrate Families** or **Internal Memory Substrate Families**, instantiating methods M1–M11 with shared hyperparameters.\n    \n3.  03\n    \n    Retrieval Depth Sweep\n    \n    Harness the Memory runs a **Retrieval Depth Sweep**, varying top-k values on LoCoMo and ALFWorld to attribute performance changes to retrieval breadth rather than scaffolding.\n    \n4.  04\n    \n    Scalability Study on MAB Conflict Resolution\n    \n    Harness the Memory performs a **Scalability Study**, sweeping conversation length from 6K to 262K tokens on MAB Conflict Resolution to measure quality and latency scaling.\n    \n\nKEY CONTRIBUTIONS\n\n## Key Contributions\n\n-   01\n    \n    Holistic Harness Evaluation of Agent Memory\n    \n    Harness the Memory delivers the first **Unified Evaluation Harness** over 11 substrates spanning **External Memory Substrate Families** and **Internal Memory Substrate Families**, three backbones, and four benchmarks with 26 metrics.\n    \n-   02\n    \n    Cross-Regime PerforLine truncated

The harness reports backend-local precision-recall curves (never a single thresholded cross-backend number), an abstention-aware headline metric, stage-by-stage latency profiles, and neutralized-metadata quality rows alongside live-composite deltas; runs are bit-reproducible under a frozen reference clock and pinned embed digest, land in the shared run-record schema/fingerprint() of orchestration/benchmark.py, and write exclusively to RUNE_*-isolated scratch stores. The graph tier (graph_memory.py) is registered as a harness-only registry source with production-faithful write-gate ingestion or an explicit fidelity caveat. This is the union of the six surviving candidates (sqlite-hybrid-retrieval as measured target, retrieval-quality-metrics-suite as metrics, reproducibility-contract as run discipline, matched-precision-comparison-methodology as reporting rules, candidate-pool-vs-ranking-diagnostic as built-in probe mode, substrate-family-comparative-eval as Rune's own tiers as the compared backends), with all ten required mitigations M1-M10 baked into the design.\",\n9:   \"why_this_design_won\": \"The adversarial adjudication confirmed the route (STANDARD_SOLUTION_SUFFICIENT) is NOT overturned — the attacks are about HOW the harness must be built, not WHETHER.

Never fabricate a stage outcome.\n15: \n16: ## Architecture decisions\n17: _Major design choices with rationale.

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

The already-implemented SQLite hybrid (`memory_store.py`) is the primary validation *target*, not new code.\n\n**Why it won**: The adversarial stage attacked *how* to build, not *whether*. This is the only shape that satisfies every accepted constraint: no second adapter protocol (M5 kills memory-adapter-protocol's mechanism while keeping its intent), mode-observability gates any \"hybrid\" claim (M1), neutralized metadata + backend-local PR curves fix the two measurement traps (M2/M4), abstention-aware metrics stop the headline number from punishing Rune's designed abstention (M7), and isolation/cache/probe-cap guards remove the three silent corruptors (M6/M3/M8).\n\n**Key structural facts grounded during synthesis**:\n- All FT1–FT7 are converted into 13 invariants + 16 concrete tests; all M1–M10 appear in design/interfaces.\n- `orchestration/benchmark.py:22` `fingerprint()` is reused verbatim (M10) — one schema, one fingerprint.\n- One location discrepancy resolved: `memory_selector.py` isn't in the subject repo checkout — the verified copy lives at `/mnt/workdrive/research-stage/src/rune/memory_selector.py` (registry `add_source` @130, `DEFAULT_SOURCES` @504, `MAX_CANDIDATES=24` @54, `DEFAULT_BUDGET=4` @58). The dossier cites the registry contract and the authority map's `ContextBroker.memory_selector` v1_owner, not the path.\n\n**Build order**: M1 mode field → M8 cap parameterization → M6 isolation assertions → M10 shared schema → harness core → metrics → stage profiler → diagnostic probe → backends (incl. FT6 graph-fidelity verdict) → scale sweep → reproducibility close-out.\n\nNo new research performed, no rejected candidates resurrected, no mitigations weakened, no new authority paths.\n\nStageCompleted: SYNTHESIS","time":{"start":1788913175112,"end":1788913182841}}}

If the harness produces invalid or irreproducible results (FT2/FT3 failure), its numbers are quarantined from decision inputs and the reproducibility machinery's cost is re-estimated before any adoption claim; the SQLite-vs-graph status quo ante (research-reasoned constants, no quality measurement) is the standing fallback state.",

Some applications can use SQLite for internal data storage. It’s also possible to prototype an application using SQLite and then port the code to a larger database such as PostgreSQL or Oracle.\n\nThe `sqlite3` module was written by Gerhard Häring. It provides an SQL interface compliant with the DB-API 2.0 specification described by [**PEP 249**](https://peps.python.org/pep-0249/), and requires the third-party [SQLite](https://sqlite.org/) library.\n\nThis is an [optional module](../glossary.html#term-optional-module).

Overview\n\nThe default method by which SQLite implements [atomic commit and rollback](atomiccommit.html) is a [rollback journal](lockingv3.html#rollback). Beginning with [version 3.7.0](releaselog/3_7_0.html) (2010-07-21), a new \"Write-Ahead Log\" option (hereafter referred to as \"WAL\") is available.\n\nThere are advantages and disadvantages to using WAL instead of a rollback journal. Advantages include:\n\n1.  WAL is significantly faster in most scenarios.\n2.  WAL provides more concurrency as readers do not block writers and a writer does not block readers. Reading and writing can proceed concurrently.\n3.  Disk I/O operations tends to be more sequential using WAL.\n4.  WAL uses many fewer fsync() operations and is thus less vulnerable to problems on systems where the fsync() system call is broken.\n\nBut there are also disadvantages:\n\n1.  All processes using a database must be on the same host computer; WAL does not work over a network filesystem. This is because WAL requires all processes to share a small amount of memory and processes on separate host machines obviously cannot share memory with each other.\n2.  Transactions that involve changes against multiple [ATTACHed](lang_attach.html) databases are atomic for each individual database, but are not atomic across all databases as a set.\n3.  It is not possible to change the [page\\_size](pragma.html#pragma_page_size) after entering WAL mode, either on an empty database or by using [VACUUM](lang_vacuum.html) or by restoring from a backup using the [backup API](backup.html). You must be in a rollback journal mode to change the page size.\n4.  It is not possible to open [read-only WAL databases](wal.html#readonly). The opening process must have write privileges for \"\\-shm\" [wal-index](walformat.html#shm) shared memory file associated with the database, if that file exists, or else write access on the directory containing the database file if the \"\\-shm\" file does not exist. Beginning with [version 3.22.0](releaselog/3_22_0.html) (2018-01-22), a read-only WAL-mode database file can be opened if the \\-shm and \\-wal files already exist or those files can be created or the [database is immutable](uri.html#uriimmutable).\n5.  WAL might be very slightly slower (perhaps 1% or 2% slower) than the traditional rollback-journal approach in applications that do mostly reads and seldom write.\n6.  There is an additional quasi-persistent \"\\-wal\" file and \"\\-shm\" shared memory file associated with each database, which can make SQLite less appealing for use as an [application file-format](appfileformat.html).\n7.  There is the extra operation of [checkpointing](wal.html#ckpt) which, though automatic by default, is still something that application developers need to be mindful of.\n8.  WAL works best with smaller transactions. WAL does not work well for very large transLine truncated

It's fantastic for local data storage, small-to-medium web applications, desktop apps, and even mobile backends.\n\nBut then, your application starts to grow. More users, more data, more concurrent operations. Suddenly, that fast, reliable SQLite database starts to feel sluggish. Writes block reads, reads block writes, and your once-snappy app feels like it's wading through mud.\n\n**The problem?** You're likely still using SQLite's default journaling mode, which, while robust, isn't designed for high concurrency or write-heavy workloads.\n\n**The solution?** A single `PRAGMA` statement can unlock a hidden superpower in SQLite, transforming its performance and concurrency profile: **Write-Ahead Logging (WAL) mode**. For many Python applications, switching to WAL mode can deliver a 10x or even greater performance boost, especially for writes and concurrent operations.\n\nLet's dive in and see how.\n\n## [](#the-bottleneck-understanding-traditional-journaling)The Bottleneck: Understanding Traditional Journaling\n\nBy default, SQLite operates in `DELETE` journal mode (or `TRUNCATE`, which is similar). To ensure data integrity during a transaction, SQLite does the following:\n\n1.  **Copies original pages:** Before modifying any database page, SQLite makes a copy of the original page into a separate \"rollback journal\" file (e.g., `mydatabase.db-journal`).\n2.  **Modifies database pages:**Line truncated

The PRAGMA statement is issued using the same interface as other SQLite commands (e.g. [SELECT](lang_select.html), [INSERT](lang_insert.html)) but is different in the following important respects:\n\n-   The pragma command is specific to SQLite and is not compatible with any other SQL database engine.\n-   Specific pragma statements may be removed and others added in future releases of SQLite. There is no guarantee of backwards compatibility.\n-   No error messages are generated if an unknown pragma is issued. Unknown pragmas are simply ignored. This means if there is a typo in a pragma statement the library does not inform the user of the fact.\n-   Some pragmas take effect during the SQL compilation stage, not the execution stage. This means if using the C-language [sqlite3\\_prepare()](c3ref/prepare.html), [sqlite3\\_step()](c3ref/step.html), [sqlite3\\_finalize()](c3ref/finalize.html) API (or similar in a wrapper interface), the pragma may run during the [sqlite3\\_prepare()](c3ref/prepare.html) call, not during the [sqlite3\\_step()](c3ref/step.html) call as normal SQL statements do. Or the pragma might run during sqlite3\\_step() just like normal SQL statements. Whether or not the pragma runs during sqlite3\\_prepare() or sqlite3\\_step() depends on the pragma and on the specific release of SQLite.\n-   The [EXPLAIN](lang_explain.html) and [EXPLAIN QUERY PLAN](eqp.html) prefixes to SQL statements only affect the behavior of the statement during [sqlite3\\_step()](c3ref/step.html). That means that PRAGMA statements that take effect during [sqlite3\\_prepare()](c3ref/prepare.html) will behave the same way regardless of whether or not they are prefaced by \"EXPLAIN\".\n\nThe C-language API for SQLite provides the [SQLITE\\_FCNTL\\_PRAGMA](c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntlpragma) [file control](c3ref/file_control.html) which gives [VFS](vfs.html) implementations the opportunity to add new PRAGMA statements or to override the meaning of built-in PRAGMA statements.\n\n---\n\n## PRAGMA command syntax\n\n**[pragma-stmt:](syntax/pragma-stmt.html)** hide\n\nPRAGMA schema-name . pragma-name ( pragma-value ) \\= pragma-value\n\n**[pragma-value:](syntax/pragma-value.html)** hide\n\nsigned-number name signed-literal\n\n**[signed-number:](syntax/signed-number.html)** show\n\n+ numeric-literal \\-\n\nA pragma can take either zero or one argument. The argument may be either in parentheses or it may be separated from the pragma name by an equal sign. The two syntaxes yield identical results. In many pragmas, the argument is a boolean. The boolean can be one of:\n\n**1 yes true on  \n0 no false off**\n\nKeyword arguments can optionally appear in quotes. (Example: 'yes' \\[FALSE\\].) Some pragmas take a string literal as their argument. When a pragma takes a keyword argument, it will usually also take a numeric equivalent as well. For example, \"0\" and \"no\" mean the same thing, as does \"1\" and \"yes\". When querying the value of a setting, many pragmas return the number rather than the keyword.\n\nA pragma may have an optional schema-name before the pragma name. The schema-name is the name of an [ATTACH](lang_attach.html)\\-ed database or \"main\" or \"temp\" for the main and the TEMP databases. If the optional schema name is omitted, \"main\" is assumed. In some pragmas, the schema name is meaningless and is simply ignored. In the documentation below, pragmas for which the schema name is meaningful are shown with a \"*schema.*\" prefix.\n\n---\n\n## PRAGMA functions\n\nPRAGMAs that return results and that have no side-effects can be accessed from ordinary [SELECT](lang_select.html) statements as [table-valued functions](vtab.html#tabfunc2). For each participating PRAGMA, the corresponding table-valued function has the same name as the PRAGMA with a 7-character \"pragma\\_\" prefix. The PRAGMA arguLine truncated

Artifact written to `research/issue-263/outward.json`. Summary:\n\n## DISCOVERY\n**Queries issued (receipts preserved):**\n- Q1 `webfetch(DuckDuckGo)`: \"sqlite write-ahead logging wal concurrency python documentation\"\n- Q2 `webfetch(DuckDuckGo)`: \"python sqlite3 busy_timeout WAL database is locked concurrent writers\"\n\n**Sources discovered:** O1 `sqlite.org/wal.html` (official), O2 `docs.python.org/3/library/sqlite3.html` (official), O3 `sqlite.org/pragma.html` (official), O4 dev.to Python WAL article (blog), O5 `sqlite.org/lockingv3.html` (official — not selected; rollback-mode locking). Selected set: O1–O4.\n\n## READING (all four fetched and read in full)\nKey evidence extracted:\n- **E1–E2** (O1): WAL gives reader/writer non-blocking concurrency, but **only one writer at a time** — the hard limit SQLite concurrency hits.\n- **E4–E5** (O1): auto-checkpoint at 1000 pages runs in the committing thread (occasional slow COMMITs); checkpoint starvation with always-on readers grows the WAL unbounded.\n- **E6** (O1 §9): `SQLITE_BUSY` can still occur in WAL mode (exclusive locking, connection-close cleanup, crash recovery).\n- **E8** (O1 §11): WAL-Reset bug fixed in SQLite 3.51.3 (2026-03-13) — a real corruption risk for multi-threaded/process concurrent writers on unpatched SQLite.\n- **E10–E12** (O2): Python-side knobs — `connect(timeout=5.0)` = busy wait, `check_same_thread`, dynamic `threadsafety` (3.11+), `isolation_level`/`autocommit` (3.12+).\n- **E14–E15** (O3): `busy_timeout` (ms) pragma; `synchronous=NORMAL` in WAL mode = no per-transaction fsync, safe from corruption but loses power-loss durability.\n- **E17–E18** (O4): Python worked example of enabling WAL and `wal_checkpoint(TRUNCATE)`.\n\n## LIMITATIONS\nNo asyncio/aiosqlite guidance in any source; no official benchmark for the \"10x\" claim; busy_timeout's interaction with WAL-mode `SQLITE_BUSY` edge cases undocumented; the advisory doesn't map SQLite versions to CPython bundles (check `sqlite3.sqlite_version` at implementation time).\n\n## CONTRADICTIONS\n1. \"Readers never block writers\" (O4, and O1's overview) vs. O1 §9's explicit `SQLITE_BUSY` cases — resolved: the no-blocking property is common-case only; apps must still handle `SQLITE_BUSY`.\n2. Checkpoint execution model: O4 claims background/reader-connection; O1 says the committing thread runs it by default — O1 (official) authoritative, O4 inaccurate.\n\nStop condition met: the single external subquestion (sqlite WAL + concurrency in Python) has adequate evidence from ≥2 unique URLs (actual: 4 read, 3 official).\n\n```\nStageCompleted: OUTWARD\n```","time":{"start":1788906168359,"end":1788906180367}}}

+## Fully-merged gitea remotes with no local branch/worktree
+
+`chore/auto-bump-0.54.1` (09-08), `chore/pi-infra-labels` (09-06), `chore/runner-label-split` (09-06), `conductor-patch-1` (09-06), `merge-robot-auth` (09-07), `research-file-245` (09-08) — all merged into master, safe to prune on the remote. Separately, **71 merged local branches** exist with no worktree (prunable refs only, no data loss).
+
+## Recommendation
+
+Twelve of the thirteen worktrees carry branches fully merged into master with no code-level uncommitted work; they are safe to prune with `git worktree remove` + `git branch -d`. Two caveats before pulling the trigger: `p1-03` holds one tiny untracked generated stats file, and `research-stage` holds untracked research-run outputs for issues 161 and 263 (events, err logs, task trees) — if those runs are still citable evidence, archive the two directories elsewhere first. The single must-keep is `m10-derive-refresh` (checked out at `/mnt/workdrive/issue161-harness`): 165 unmerged commits of T54 orchestration/context-pressure work plus in-flight browser_mode code (new `src/rune/browser_mode.py` and tests, modified canary manifest and spine/scaffold state) — deleting it would lose roughly three weeks of unmerged feature work. On the remote, the six merged `gitea/*`-only branches can be deleted outright; the 71 merged local branches without worktrees are pure clutter and can be batch-deleted with `git branch -d` at the owner's discretion.

+# test_cleanup_orphan_rune.sh — T23 red-first fixture for the orphan
+# cleaner's age-guard inversion.
+#
+# The incident (2026-10-18/19): the guard reported "0 orphans" while two
+# hot-looping leaked serves were alive — the zombie-parent class; both
+# had to be killed by direct PID + parent kills. Two guard shapes keep
+# a leak alive, and this fixture reproduces both:
+#
+#   1. THE LIVING-PARENT INVERSION — a parent that is alive but WEDGED
+#      (hot-looping) reads as "the owner's TUI owns this serve" when the
+#      guard's only liveness signal is a non-systemd cmdline. A wedged
+#      parent never reaps and never tears the serve down.
+#   2. THE ZOMBIE-PARENT CLASS — a zombie-leader parent (stat state Z:
+#      the TUI's main loop exited, threads may still spin) must not
+#      count as an owner either.
+#
+# And the age-guard half: the "newest serve is never killed" protection
+# only makes sense while a LIVE session exists (a candidate with a
+# living owner parent). With no live session, every non-owned
+# candidate is a leak — newest included.
+#
+# The fixture spawns four fake `/tmp/rune-tui-lib-test*/rune-entry
+# serve` processes — A under a zombie-leader parent, B under a
+# hot-looping (wedged) parent, C under a healthy sleeping parent, D
+# under a second zombie-leader parent (D is the newest candidate) —
+# plus E, a leaked `/tmp/*/rune-tui` test-TUI binary under a
+# zombie-leader parent (the hot/test leak class). The cleaner runs in
+# DRY-RUN (it never kills anything outside the fixture) with its scan
+# seams (RUNE_TUI_LIB_GLOB / RUNE_TUI_TEST_GLOB) scoped to the fixture
+# dirs, so real host serves cannot perturb the verdicts:
+#
+#   phase 1 (live session exists via C): A, B orphans; E orphan;
+#           C kept (owned), D kept (newest, live session).

+//   - A1: the state derives from REAL dispatch signals only — the turn
+//     state machine (a dispatch in flight), the mode (a PLAN-mode
+//     dispatch), and the tool names observed in the current turn's
+//     loop. No guessed classifiers; a misfiring label is a defect.
+//   - A2: per-activity colour + animation; the runic marks are KEPT and
+//     may randomise colour per rune within the activity's palette.
+//   - A3: the activity word randomises a rainbow colour while active.
+//   - A4: NO timestamp on the pane.
+//   - A5: the pane NEVER disappears; content changes with state (idle
+//     rests: the runic marks absent, the word dim).
+//   - A6: a clickable + affordance opens the CENTERED WINDOW with the
+//     full current-turn processing (full thinking text, tool calls in
+//     flight, one block per full answer). In-place click-to-expose on
+//     the strip is REMOVED.
+//   - A8: this is an independent layer — own state machine, own tests.

+// lines at a width; Render draws the borders around it.
