Failure taxonomy v17 — class reference

commitwork · oversight failure classification

In one sentenceAI coding agents fail most dangerously when the failure looks like success — a clean report over work nobody checked, a fix that silenced the alarm instead of the fault, a record crediting the wrong author — and this page names every such failure we have measured, one row each, with the incident that earned it its place.

For the fieldFormally, it is a registry of oversight-failure classes for agentic LLM systems: each class is a falsifiable predicate over artefacts, bound to an STPA control loop, an unsafe-control-action type and a causal factor, scored for closure and residual gain, and linked to its neighbours by a closed set of causal relations, so that inter-rater agreement, coverage and drift are measurable rather than asserted.

207 classes · 11 families (I 37 · II 24 · III 18 · IV 17 · V 29 · VI 27 · VII 17 · VIII 7 · IX 14 · X 5 · XI 12) · verified against 2026-09-02 14f05f8 · generated by bin/taxonomy-render.mjs from monitor/failure-taxonomy.json — do not hand-edit.
Families I-VIII were declared in v1 and v3; IX and X are numbered here for the first time, without renumbering any existing id. Family XI (collective action, prefix L) is numbered in v9, again without renumbering any existing id. SCOPE (operator ruling, 2026-09-02): the taxonomy includes ALL AGENTIC SOURCES and is REPOSITORY-INDEPENDENT. The classes describe how oversight of agentic work fails, not how one codebase fails, so an instance qualifies on its mechanism and never on where it was found — instances from teamDRemote, overwatch-layer and memory-layer are already held, and an instance from a repository this fleet has never touched qualifies equally. The requirement is attribution, not provenance: every instance names the repo and the session that measured it, because an instance from one population recorded as if it came from another is M1. An earlier version of this line said "fleet-scoped", which was my inference from what had been folded rather than a stated policy; it was narrower than the truth and is corrected here. FAMILIES CARRY A MEMBERSHIP TEST from 2026-09-07: the sentence a second rater applies to decide whether a class belongs, in the same form the stpa, rca and mitigation vocabularies already require. Added after family VI was measured as the one family whose members are more like another family's than like each other; a family that declares only a proposition cannot refuse a member. The tests are DECLARED, not enforced against existing membership, because moving a class renumbers it and breaks every citation.
STPA++ layer, the top line of the column: CONTROLLER decides what runs, on what, in what order, and what the result means · IMPLEMENTER does the work · BOTH both.
Scores, two meters under each id — closure 0 = nothing stands between us and this class; 4 = fixed and pinned by a test or canary: closure0 not solved · closure1 barely · closure2 part-solved · closure3 solved, unpinned · closure4 solved and pinned
gain 0 = nothing further on the table; 4 = the largest remaining win, impact x tractability: gain0 nothing on the table · gain1 marginal · gain2 worth doing · gain3 high · gain4 biggest available.
Scores are one rater. closure and gain assigned by a single rater, who authored both the classes and the remediations the scores rank. No inter-rater pass. MC-family spread on this repo has been measured at 6.0/10, so treat these as one reading, not a measurement. SECOND PASS 2026-09-06 by reporter #3, over all 199 classes, from each scoreBasis, the remediation register's status text and the presence on disk of every mechanism either names: 28 scores changed, 171 confirmed. Rubric applied uniformly — closure: 0 nothing stands between us and the class; 1 a convention, sensor or one-site fix; 2 a mechanism that exists and runs, partial or unpinned; 3 solved for the population it names, unpinned or pinned at one site; 4 fixed and pinned with no instance measured since. Gain is impact times tractability: 4 fleet-wide impact with a named session-sized mechanism; 3 one of the two; 2 moderate; 1 marginal; 0 nothing on the table. Two rules produced most of the changes: an instance measured after a closure-4 score caps closure at 3, and a register mechanism the code confirms raises closure to at least 2. Still one rater at a time; the two passes disagree on 28 of 199, which is the only inter-rater figure this registry holds. LEVER TRIAGE 2026-09-06, same rater: every class then without a mitigation record was judged for a code-base lever; 5 scores moved, each rise citing the test or rule that holds it.
STPA, under the STPA++ layer tag: uca how the control action was unsafe · cause the causal factor · judged in the loop numbered beside them; a second line is the same class judged in another loop. Hover a value for its test. Loops, numbered for reference (controller → controls): 1 operator (the operator → fleet configuration, manifests, schedules, rulings, suppressions) · 2 monitor (the monitor: sweep, rollup, issue store, freshness, liveness, pages → scanner runs, the issue store, published rollups and pages) · 3 scanner (a scanner lane → its own run over a repository) · 4 agent (an agent session → the working tree, ledgers, commits, handoffs) · 5 oversight (hooks, gates, raters, overwatch-layer → the agent session) · 6 attention (the monitor's publication: rollup, panel, page, handoff, evaluation → operator attention).
Causal edges: same-defect-as 22 · mechanism-of 9 · enables 3 · masks 0 · awaits 2 (1 deadlock) · assessed-none 19 · unassessed 163.
STPA is one rater. two machine readers per class: one assigning per family from the class text, one blind re-rating a sample against the vocabulary tests; under operator rulings of 2026-08-23 (report is a control action; loop names the reading), 2026-08-23, primary entry judged in the loop the description sits in; attention entry added where the class's consequence is a verdict published to the operator; each value chosen by its vocabulary test; blind-sample disagreement rate recorded in this field by the merge step. machine-rated on one registry edition; where a description straddles monitor and agent the primary loop follows where the example sits; disagreement rate: PENDING
Mitigation layers, one row under each class: commitwork remediation. States: implemented partial open wrong superseded unassessed no-lever · no record nothing recorded for that layer. Hover a state for its test.
Mitigation records are one rater. reporter #3, 2026-09-06, Seeded, not judged: commitwork records come from the remediation register and attribution plan (closes → class, status word → state, R1 excluded as stale) and from mechanisms named in a scoreBasis and confirmed present on disk the same day; vscode-skills, memory-layer and overwatch-layer records come only from what a scoreBasis states a product does, with the sha or file re-resolved in that repository. Proposals come from the register's own REMAINING sections and from the wins the second scoring pass named. Lever triage 2026-09-06 (same rater): every class that had no record was judged for a code-base lever — a mechanism the basis names and the tree holds became an implemented or partial record; a predicate no mechanism here can decide became a no-lever record with the reason; a lever that exists and is not built became a proposal. Four lexical ratchets, two registry rules and one land-time warning were armed the same day and recorded as partial.. Classes with a record per product: commitwork 150, vscode-skills 5, memory-layer 6, overwatch-layer 7; 36 of 199 carry no record on any layer, and 43 carry a no-lever record, which is a judgement that no gate exists here and not a clean. Proposals stand on 66 of the 181 classes with closure possible and gain remaining. One rater seeded and triaged it from text; a record reads "verified" only where its evidence says so.

Layers commitwork — what is being remediated — what helps, or has been implemented proposed — what we propose adding, on every class with closure possible and gain remaining Toggles hide rows on screen only; print carries every layer.

IFalse cleanC1–C37 The false proposition: “nothing is wrong” membership testThe subject is reported as having nothing wrong with it, and that clean reading is indistinguishable from the one a check would produce if it had never run, never reached the subject, or could not have failed. The defect is in the CLEAN READING. A row whose finding exists and is merely wrong belongs to family II.

Measured instance, CI green while deploying nothing for four weeks, repo teamDRemote: a workflow granted id-token: write and commented that no long-lived credential was needed, then passed DENO_DEPLOY_TOKEN from secrets anyway. An UNSET GitHub secret expands to an EMPTY STRING rather than being omitted, so the step handed the deploy a blank token which shadowed the OIDC credential — and that tool exits 0 on refusal. Every push since the secret lapsed on 2026-08-05 ran the job, deployed nothing and showed a tick. Fixed c891c48 by removing the env block and asserting on "Successfully deployed" in the output rather than on the exit code. Measured instance, cra/soc2.mjs 2026-09-24: SOC 2 CC7.4, respond to identified security incidents, carried evidenced: true as a literal, so a product with no case and no recorded risk decision rendered 'evidence present' beside an evidence line reading 0 and 0, in a packet documented as feeding an audit (audit finding 0003). Fixed f28b7a6: evidenced requires a response record, as CC7.2 and CC7.5 already did. Measured by reporter #1 2026-09-24.

FOUR CARRIERS NAMED, measured 2026-09-06 in commitwork by reporter #26 and independently held as the baseline of bin/test/lexical-ratchets.test.mjs's spawnSync ratchet (9309cb9): bin/commitwork.mjs:1025, where a failed `find` discovers zero repos and says so in the same voice as a clean tree; bin/session-start-roster.mjs:84, since fixed at 7430ee3; monitor/workflow-harden.mjs:154; bin/commitwork.mjs:2319. The ratchet keys them on file::identifier rather than line, so the set can only shrink. Measured instance, bin/commit-phase.mjs 2026-09-24: step 6 re-syncs the shared index after the ref update with allowFail, and the result was discarded. The same day the private sidecar's shared index held none of the seven launchlist store files its HEAD tracks, so a bare commit there would have untracked the store; the two commits that added those files were written through a private index. Whether a repair failed or never ran is not recoverable from any record. Fixed 3896268: a failed repair prints the git error and the repair command, pinned by an e2e test that holds index.lock. Measured by reporter #1 2026-09-24.

M1 is the general mechanism (a wrong-population comparison, whether it reads clean or not); this is M1's false-clean-producing case. analogyA doctor reads yesterday's chart for the patient in today's bed. example"You broke 69 tests" was measured on a tree three sessions were writing; the true floor fifteen minutes later was 1.

Measured instance, 2026-09-24: audit queue ids are positions after a sort on disposition, severity, file and line (bin/reconcile-findings.mjs), so every fix and every line move renumbers what follows. The build-fixture finding was cited as 0066 in sitemap/README.md on 2026-09-23, read as 0065 at 17:30 on 2026-09-24, and numbered 0062 after a regeneration at 21:31 the same day. FIXED_LEDGER binds by file and summary pattern and is unaffected; the README citation and every handoff that quotes an id are not. Measured by reporter #1 2026-09-24, with a read-only review agent of the same session.

C5closure1gain3	Tooling self-deception	false_clean.instrument_lies	IMPLEMENTER2 monitornonefeedback-incorrect6 attentionunsafe / actuator-corruptunassessed	The measuring instrument lies in a way that specifically produces a clean reading: a search suppresses matches, a probe reads the wrong field. M3 is the general form, including instruments that lie loud rather than quiet. analogyA broken thermometer reads 37 in every room, so nobody in the ward has a fever. exampleUnder a C locale, grep withheld matching lines in bin/bola-run.mjs while grep -c still counted them, producing four consecutive false "this symbol is gone" conclusions. Second instance, where the control is the finding: sweeping ~/.claude for three identity strings with rg returned 0 files for all three, because rg skips hidden and ignored paths by default and ~/.claude is hidden. Control terms on the identical command shape returned 4,820, 4,105 and 2,290 files, which is the only reason the zero was disbelieved; re-run with -uuu gave 527, 1,349 and 2,184. A published 0/0/0 against a true 527/1,349/2,184. Third instance, and a third mechanism — config-root resolution rather than a search filter: in teamD (Portll/teamDRemote, NOT this repo), a `// deno-lint-ignore react-no-danger` suppression was verified by copying the file to /tmp and running `deno lint` on the copy, which reported "Checked 1 file", 0 findings. deno lint resolves config by walking up from the TARGET file, so from /tmp the site's deno.json never loaded and the fresh-tagged rule was never enabled. Byte-identical file via cp: `deno lint /tmp/copy.tsx` gave 0 findings while `deno lint routes/_app.tsx` from the site root gave 3 problems including error[react-no-danger] at routes/_app.tsx:84:14. The 0 meant the rule did not run, and "Checked 1 file" is the same string either way.

Second instance, mis-baselining against a remembered number in a tree with live peers: `deno fmt --check` in teamD/site read 153 unformatted of 329 early in a three-day session and 162 of 332 late — an apparent +9 attributable to that session's own work. The true delta was +3. Establishing it required stashing only that session's changes and re-reading the baseline at 159 of 332; peers had landed c891c48 → 98e2e1c → 942724c underneath, moving the baseline 153 → 159. Six files of peer-introduced debt were about to be attributed to the wrong writer. The error is symmetric: had the peers FIXED six files, the same stale number would have concealed nine of the session's own. teamD / Portll-teamDRemote, reporter #29, 2026-09-04.

Every existing checkout keeps passing because the local half is present, and a fresh checkout fails for everyone but the author. analogyThe bridge opens with one bank still under construction. exampleA cross-file invariant was committed in one file while its counterpart stayed uncommitted, so the suite was green in the only tree anyone was running it in. Measured instance, and the second form of the predicate — a rename applied to a proper subset of its call sites rather than an uncommitted file: a release-redaction pass renamed a module and rewrote its importer to the new path and committed that, while the target rename stayed in the INDEX only. HEAD therefore carried an importer whose module was not in the same tree and the panel could not boot for anybody — six admin tests failed with ERR_MODULE_NOT_FOUND, one cause. Every local check answered the author-tree question and passed: node --check, the import resolving from the working tree, and 1055 admin tests. It surfaced only because one test boots the panel inside a HEAD WORKTREE. Fixed 4b788fa. Second instance, committed BY the repair for the first one: 4b788fa landed the missing half of a rename to unbreak HEAD and deleted lib/internal-c-client.mjs while five files at that same commit still imported it (admin/lib/internal-c-sync.mjs, bin/ab-loop.mjs, bin/internal-c-migrate-tenant.mjs, bin/test/internal-c-client.test.mjs, monitor/export-overwatch.mjs). `git cat-file -e 4b788fa^:lib/internal-c-client.mjs` confirms the module was present at the parent, so the commit removed it out from under all five and HEAD was broken again immediately, by the fix. Peers repaired them over the following hour, the last at 3029d3f. Measured instance, 2026-09-24, across two repositories: monitor/corrected-history.mjs hardcodes its area slug as the tracked tree's pseudonym, with a comment saying the private registry declares the same slug. The registry's rename to that slug was uncommitted in the private sidecar. At the committed registry the slug is undeclared, the resolver falls back to a directory named after the slug, and the foreign-area guard cannot fire, so the tool would write its corrected view into a directory no registry declares.

Unlike a guard that never executes this one runs, and its emptiness is indistinguishable from a pass. analogyThe turnstile counts everyone presenting a ticket of a kind nobody carries. examplemonitor/anchor-disposition.mjs keys on a field its rows do not carry and stands unwired in draft. Measured instance: a check for four unknown-states built its word boundary as '\b' inside a JS template literal, which collapses to a BACKSPACE character in the page. The regex ran against every state, matched none, and the tool printed "window attribution shows 0/4 distinct states — a missing one has collapsed into another". All four states were rendering correctly. c624d17. Second instance, different language feature, same place: a guard against a 200 carrying no payload was written `body.data ?? body`, and the nullish fallback yields the WHOLE ENVELOPE when data is explicitly null — so the object test passed and the check was defeated by the exact case it existed for. Fixed by asking whether the KEY is present rather than whether its value is truthy.

The second witness's observation channel is inert — it runs, exits cleanly and observes nothing — and the reconciler consumes its empty output as concordance rather than as a null. Agreement is computed rather than observed, and a null observation agrees with every claim; the more thoroughly the second instrument is broken, the higher the agreement score. The statistical signature is the mirror of the ~100%-failure heuristic: near-perfect agreement between two witnesses is as much a defect signature as universal failure. Distinct from K5, where correlated verifiers make agreement CHEAP — here the channel is absent, so agreement is CERTAIN. Distinct from C13, whose remedy is to publish the subject count beside the finding count: this one's remedy is a liveness precondition, that a corroborator prove it can observe before its vote is counted. analogyTwo surveyors agree the field is empty. One of them was facing a wall. exampleA runtime dataflow witness built as a module preload. Measured 2026-09-02 before any code was written: --import intercepts a default import and MISSES a named import of a builtin, because importing a builtin instantiates its ESM facade and freezes the named bindings; the named form is the commonest in this tree. The witness would have observed nothing while exiting clean, and every static edge would have read as uncontradicted. -r with require intercepts all four import forms. DEGENERATE RATHER THAN EMPTY, measured 2026-09-16 on a 200-repository COBOL corpus, which is why this row predicate now asks for proportion rather than presence. A differential check graded a subject parser against GnuCOBOL 3.2 listings. cobc -fsyntax-only -t list -Xref -ftsymbols exited 0 on a 426,757-line fixed-format program read as free format and produced a symbol listing with 4 entries, which is byte-indistinguishable from a correct answer key over an empty subject. Across 1,726 witness runs 32 listings were degenerate, and 29 of those came from a repair pass that retried failing files with the source format flipped, so the repair manufactured the false witnesses and converted a loud failure into a silent wrong answer. The gate that works is a ratio against a lower bound neither side produces: reject the witness when its level-01/77 count is under half of a plain regex count of level-01/77 lines in the source. Before the gate the affected files scored the subject at 63.8% item recall; the same subject scores 99.8% once they are excluded, so the degenerate 1.9% moved the headline by 36 points.

The forward half is built, tested and reported; the converse has no implementation, no store, no surface and no reader, so the class of finding only it could produce is not missing from the report — it is unrepresentable in it. The published number then reads as THE coverage figure while answering half the question. Distinct from R6, which is decided by enumerating surfaces that exist and counting invocations: here there is no surface to enumerate, and zero throughput and zero implementation are different states of which only the first is countable. Distinct from G7, which has a writer and no reader — this has neither. Distinct from C13, whose scan RAN and enumerated zero subjects: C13’s remedy is to publish the subject count beside the finding count, which cannot be done here because no scan for that direction exists to have a subject count.

Rewriting the content is then indistinguishable from deleting one record and creating another, and the tool performs that delete-and-create silently, as an ordinary successful run. Distinct from C29, and this is the discriminator that matters: C29 is repairable by a better key. A path moves and the file's content stays, so rename detection recovers the identity; C4 is the same shape one level down, where a line moves and the place stays. Both have something stable to fall back on inside the key. Content-keyed identity has none — when the moving thing IS the content, normalisation buys only the cosmetic cases (whitespace, case, unicode composition) and a genuine reword is movement by definition. The remedy is therefore not a better key but a change of AUTHORITY: the matcher may propose a link and must never assign one. That makes this the only member of the family whose repair is a refusal rather than a redesign. analogyA registrar who decides you are a new person because you changed your name. exampleMeasured 2026-09-02 in a requirement differ.

C34closure0gain3	Denominator outside the consumed artefact	false_clean.denominator_outside_artefact	IMPLEMENTER3 scannernonesensor-inadequateassessed-none	A tool serialises only positive results into the artefact its automation consumes, and reports what it examined on a different channel. An empty result set is therefore byte-identical for "read everything, found nothing" and "read nothing", and no consumer of that artefact can tell the two apart however carefully it parses. analogyThe inspector files a list of the faults found and mentions how many rooms were entered on the way out of the building. exampleMeasured 2026-09-02 over three composer.lock files: osv-scanner 2.5.0 serialises only packages that HAVE vulnerabilities into results[].packages[], so two repos returned empty arrays and were nearly reported as having no coverage. The scanner's own stderr carried the denominator — "Scanned … and found 36 packages" — and the table format printed "No issues found". Actual state: 36, 132 and 222 packages read, one advisory total. The JSON was correct and unreadable, and the two channels carrying the denominator are the two an automated consumer does not parse. THE INVERSION, measured 2026-09-02 on scalafmt 3.8.1 while wiring the build-health format lane: `scalafmt --test` puts the per-file diffs on STDERR and only `error: --test failed` on stdout — 21 bytes out, 851 bytes err, both `+++ b/` headers on err, exit 1. A stdout-only consumer gets a non-zero exit and ZERO parseable records, which foldFormat correctly folds to `unreadable`, so every unformatted Scala repository in the fleet would have reported unreadable rather than a count. Same channel split, opposite half displaced: osv-scanner keeps the findings and loses the denominator, producing a false CLEAN; scalafmt keeps the verdict and loses the findings, producing a false GREY. The remedy differs with it — osv-scanner needs the base fetched from the other channel, scalafmt needs `2>&1` at INVOCATION, which lives in the manifest's cmd string where no parser test can reach it. Nothing downstream could have caught it; the split was measured before the command was written (commitwork 09682a8).

Recovered at 661d4ec (2026-09-16) with a legacy splice arm, 24 of 24 recovered and 0 of the 9,926 good records taking the arm. The landing commit asserted "Both bincode round-trip tests still pass" as evidence of backward compatibility. They did pass, and they always would have: both encode and decode through one struct definition, so no fixture either of them can build carries the old layout. The two tests are named for the risk they do not cover, agent_session_default_bincode_round_trip and agent_session_populated_bincode_round_trip at src/memory/facets.rs:1204 and :1223, and their existence is why nobody looked further.

A gate that matched nothing would eventually be noticed by its zero rate; this one has a rate and a hole, and the rate is evidence for the proxy and against nothing. analogyThe inspector checks the passengers who are standing still. exampleMeasured in commitwork. bin/lib/turn-gate-core.mjs reportLoop requires runs of consecutive turns that produced text and called no tool (policy reportLoopRun, default 3). Run against the session that built it, turn-gate returned outcome: pass on all four rules, reporting that the longest toolless run was 0, across 263 tool calls in 12 model turns, while three consecutive turns ended on the same unmoved hand-back. The activity is what hid it. Closed by a second rule, carried-handback, which keys on the handed-back ITEM with the hand-back phrase stripped and is therefore insensitive to how busy the turn was: a5d5f17 and 26dee25, 2026-09-16. Over a corpus of 266 transcripts, 4 sessions fire at run limit 3 and all 4 adjudicate as true positives; limit 2 fires on 12 and is unadjudicated. One of the four true positives is a destructive action correctly refused and then restated three times rather than escalated, so the class includes correct refusals that were never converted into a decision.

C37closure0gain3	Verdict inherited by later members	false_clean.verdict_inherited_by_later_members	CONTROLLER5 oversightnot-providedcontroller-modelassessed-none	A grouped result is classified once, correctly, and the classification is then reused as membership. Entries that join the group afterwards inherit a verdict nobody formed about them, and the standing entries keep that verdict looking confirmed on every re-read. Nothing that is read is stale: the PARTITION is, which is why a freshness check on the data finds nothing wrong. analogyThe supervisor signs off the tray of approved forms each morning and clerks add forms to the tray all day. exampleMeasured in commitwork. 008b015 set scopeNotes to a string where manifest.schema.json requires an array, and the manifest-schema-drift failure "every real manifest satisfies the schema" fired for hours inside the gate block of failures already classified as committed and attributable. Counted afterwards: at 008b015 exactly one check carried a non-array scopeNotes, the reporter own, the only one in the tree; zero at HEAD; 4 of 4 valid now. The block held between 2 and 9 entries throughout, so volume is not the mechanism. A peer repaired it at c0a38fc and 2bd2947; records at 658fea1 and 17fbcee. The remedy is mechanical and the gate already has the data for it: diff the failing test names against the previous run and print what is new since it as its own block, so that membership is computed rather than remembered and the reader has no opportunity to misclassify.

Measured instance where the fail-open was introduced BY the fix for a lockout: an idempotency guard's liveDispatchFor DID ask upstream, upstream was unreachable and returned {known:false}, and the release path treated "could not ask" identically to "asked, and the session is gone" — so a moment of unreachability let a second agent start on the same task. Fixed 4b788fa by making the decision an exported three-state function, precisely because a fail-open hides well in an inline conditional. Further instance in this fleet's own roster walk (d2e3ac8): sessionPid read ps's OUTPUT and never its STATUS, so a ps that could not run at all — missing binary, denied, exec failure — produced an empty stdout, a NaN parent and a null return BYTE-IDENTICAL to "walked the chain and found no socket ancestor". Both fail closed and the hook omits the pid either way, which is why it survived review: the observable behaviour was right. What differed was everything around it — the failing spawn repeated once per hop, twelve times per session start, on every session on the machine, and nothing could tell an operator that ps was broken here rather than that no session owned this process. A fleet-wide roster outage would have looked exactly like normal operation.

The cause is destroyed as the message is written, not lost in transit and not merely unrecorded, so no downstream reader can recover it however carefully they look. analogyThe hospital records that the patient was discharged and not what was wrong with them, on a form that has a box for it. exampleTwo instances one layer apart in the same incident chain, in two independent programs. ggml/llama.cpp's shipped libggml-metal.dylib carries BOTH "%s: error compiling source" and "%s: error compiling source: %s", and the lossy one is on the path that runs, so the Metal compiler's actual diagnostic reaches no log — lmstudio-ai/lmstudio-bug-tracker#2040 stood 58 days with the cause hypothesised and unproven. One layer up, LM Studio's wrapper logs "Engine protocol runtime llama-server for <id> exited before becoming healthy. exitCode=1, signal=null" and its main.log holds that line, GPU config and nothing else; the child's real stderr ("unknown model architecture") existed only in ~/.lmstudio/server-logs/, which is why the operator's first question was about RAM. REMEDIATED UPSTREAM, and the remediation is what makes the class legible: on llama.cpp 2.31.2 the probe now succeeds, by positive witness rather than by absence — `setLanguageVersion:` appears once in 2.31.2's libggml-metal.dylib against zero occurrences in 2.28.2, while the binary is still built minos 14.0 / sdk 14.5, so the language version was pinned rather than the SDK moved. The failure string is STILL PRESENT in the 2.31.2 binary and no longer prints on the same invocation that printed it on 2.28.2, which is the negative control for that positive one. But BOTH format strings remain — "%s: error compiling source" and "%s: error compiling source: %s", same pair, same binary. The lossy path was never repaired; it stopped firing because the compile now succeeds, so the A24 predicate still matches the current artifact. Two instances, 2026-09-24. map/render.mjs printed '(skipped, layer data absent)' for every attach-layer failure while the caught error carried the child's exit status, so attach-program's deliberate exit 1 read as a missing layer (audit finding 0037, fixed e3385f1). bin/tls-headers-scan.mjs ran testssl with stdio ignored and kept 80 characters of the exception, so a refusal such as testssl's stop on an existing --jsonfile surfaced as 'failed/timed out' with no reason (fixed 8c7937f, which keeps the exit code and the stderr tail).

IIIFalse repairR1–R18 The false proposition: “and it is fixed now” membership testA repair, guard or remediation is in place and is credited with a property it does not have, because it cannot run, runs over less than it claims, or changed only what a detector matched. The row requires an ATTEMPTED FIX to exist; a defect nobody has tried to repair belongs elsewhere.

R1closure2gain3	Guard wired to a path that cannot run	false_repair.guard_on_unreachable_path	IMPLEMENTER5 oversightnot-providedactuator-missing6 attentionnot-provided / actuator-missingawaits→ R6deadlock	A cleanup or check hangs on a branch reached only when the failure did not occur. analogyThe lifeboat drill runs on the days the ship stays in port. exampleThe stale-worktree prune sat inside suiteAtHead(), which runs only on regression-pending; the gate exited 0 with 18 directories still there. Second instance, a different mechanism reaching the same place — a correct refusal wired to a value no writer can produce, in memory-layer (src/memory/compression.rs, fixed edfb43f 2026-09-02): decompress() carries a match arm for the hybrid strategy that refuses and reports the content unrecoverable, and it could never execute, because compress_hybrid() calls compress_semantic() then compress_lz4(), and compress_lz4 writes compression_strategy="lz4" unconditionally as its last act. A hybrid record therefore reached storage tagged lz4, decompress() took the lz4 arm, succeeded, and returned the 50-word semantic summary AS the restored original; is_lossless() returned true for the same reason. Measured consequence on one real record: a 19,396-byte three-file handoff reduced to 410 bytes of content, 1.6% coverage by shingle against the source files on disk, files 2 and 3 of 3 absent entirely, while ner_entities still carried offsets to end_char 17392 into text that is nowhere. compression_ratio and the entity offsets both retained the shape of the original after the original was gone. Second instance, same mechanism at a different site: liveness's ranking logic sat in the `else` branch, entered only when a journal EXISTED — that is, only when the never-written failure had not occurred. Measured: 28 areas carrying fresh rollups and zero journals, no alarm raised, for a day. Fixed 6977431 (monitor/liveness.mjs ~193-206 pre-fix). Fourth instance, and the branch is unreachable by ARITHMETIC rather than by control flow: a new-since-last-run comparison required prevTests === tests before comparing anything, on a fleet where the case count changes between nearly every run — 7325, 7494, 7541, 7636, 7644 and 7673 were all observed on 2026-09-06 alone. The guard would therefore have refused to compare essentially always, reporting "unknown" forever while looking implemented. Found by the author auditing their own two commits at the operator's request (1b9b962), which also found the block reached one of four reporting paths.

Second instance on an orthogonal axis: the canary harness covers 2 of 4 GATES. docs-doctor has zero scenarios despite journaling 146 decisions, and liveness has zero, while the harness prints "11/11 correct" without stating anywhere that the population is two gates. Third instance, in a linter rather than a harness: golangci-lint suppresses its own output through three compounding defaults (max-issues-per-linter 50, max-same-issues 3, uniq-by-line true). On one Go tree the default output reported 32 issues; with the first two at 0 it reported 84; with uniq-by-line also off, 87.

Second instance, where the tool's own remediation hint is the vector: deno_lint's no-unused-vars advises “prefix it with an underscore like _error”, which is correct for identifiers and wrong for object-destructuring keys, and does not say which. Applied at teamD/site/routes/admin/users/index.tsx:103 it turned { url, state, data } into { _url, _state, data }, which binds properties NAMED _url and _state that do not exist; the lint finding cleared correctly, because those bindings really were unused. deno check caught it (TS2339, Property '_url' does not exist on type 'PageProps'). The IDENTICAL edit at routes/admin/users/[id].tsx:292 was silent, because that file's `data` is loosely typed — the same defect detected in one file and invisible in the other, decided by the target's type strictness rather than by anything about the defect, and found only by grepping the tree for the pattern afterwards. 2 wrong of ~30 applications; the other 28 were params, catch bindings and array destructuring, where the hint is right. teamD / Portll-teamDRemote, reporter #29, 2026-09-04.

THE DAMAGE INVERTS, and the inverted form is worse. Measured in teamD / Portll-teamDRemote by reporter #30, 2026-09-04: a TODO that predates a security fix reads as a GAP and invites the work that reverts it. license-management/index.ts:387 said to call a `create_license_materialization_job` RPC whose EXECUTE was granted to authenticated in 20251120230001 and REVOKED in 20260709000001 — the function runs as the authenticated user, so following the TODO returns 42501 on the request that takes the customer's money (corrected to a warning, c64584b). admin/users/[id].tsx:243 said to add permission synchronization logic that already existed as a SECURITY DEFINER path hard-refusing non-global admins; a second write path would have landed where the repo's IDOR fixes cluster (9a29cd1).

R15closure0gain3	Landed but not deployed	false_repair.landed_not_deployed	CONTROLLER5 oversighttoo-lateactuator-delayedunassessed	A correct, merged, pinned fix does not reach running processes. Fixed and still failing are simultaneously true, and a reader told only the first hunts for a second defect that does not exist. analogyThe recipe is corrected and the kitchen still cooks from the printout. exampleA merged fix was consumed as in force while the running process still carried the old code. Measured instance, verified in both directions: psalm crashes on any PHP codebase referencing NAN because TLiteralFloat::getKey() builds 'float(' . $value . ')' and PHP >= 8.5 raises on the coercion, killing the Amp worker and failing the run — it took out 3 of 10 PHP repos scanned. The fix exists upstream and is not released: is_nan guards were added on the 6.x branch (ca15124, 9d6db9e, authored 2026-02-19), `git show 6.16.1:...TLiteralFloat.php \| grep -c is_nan` returns 0 against 3 on 6.x HEAD, and the fix is not an ancestor of the 6.16.1 tag that brew and composer both resolve to. Swapping only that one file into a pristine 6.16.1 install takes the run from rc=1 to rc=0 in 43s, and restoring it reproduces the crash. Second instance, measured by probe rather than inferred from the commit: overwatch-layer e942994 landed a --settings seam at 2026-09-02T20:05 while the running server had started Sep 1 17:29, so the process silently accepts-and-ignores the parameter. Dispatching with a nonexistent settings path returns ok:true where the new code refuses with BAD_DISPATCH — the discriminator that separates "landed" from "in force". It would have been reported as an enforced security control had it been wired on the strength of the commit.

It is believed complete because the witness passes, and the next run reproduces the class elsewhere. analogyThe leak is patched where the water showed. exampleA fix matched the observed instance's shape and the following run surfaced the same class at a different site. Measured instance with site and count: renaming a redacted identity across commitwork changed 286 occurrences in 73 files plus 8 git mv renames, written against the observed lowercase shape; the next measurement found 4 occurrences of the capitalised form surviving in 3 files (bin/ab-loop.mjs, lib/memory-layer-client.mjs:2 and :269, schema/memory-layer-contract.schema.json:4). The guard could never have caught it: bin/test/release-names.test.mjs tests for the ORIGINAL name, not for the residue of its own remediation. A second instance the same day: overwatch-layer/.githooks/pre-commit unsets seven GIT_* variables around its npm test step and explains why, while the artifact-gate step twenty lines above does not — same artifacts, same instant, clean environment 14/14 pass, GIT_DIR set as git leaves it for a hook 1 of 14 fails. A third: a dead import was fixed in the one file that broke, while commitwork's tracked docs cite 63 code paths of which 4 are dead (161af57). THE BOUND IS THE SCOPE, and this form is decidable before the next run rather than after it. Measured 2026-09-18 in the commitwork host sandbox (bin/lib/sandbox.mjs, symlinkReads). A denied read of a symlink at depth 1 was repaired by walking the tree two levels, which passed its fixture; the next denial on the real checkout was a link at depth 3, repaired by walking four levels, which passed its fixture too. Each bound was minted from the failing instance and each fixture was built at the depth of the last failure, so the fix was exactly one instance behind the next occurrence, twice. The problem has no depth: it is every symlink the tool may reach. The landed walk is unbounded over the exclusion set the scanners already use and resolves 6 targets in 263 ms (fb30256f), and the file now carries the fact as a comment, that every depth cap missed one. Counted on the checkout at ruling: 25 links, of which 15 sit under reports/ and .claude/worktrees/ and are skipped by that same list. THE TELL, which is the contribution and is cheaper than R17's own: the number in the fix appeared nowhere in the problem statement. A literal bound introduced by a repair must cite where in the problem it comes from, and a bound whose only source is the failing instance is refused. Separations supplied by the reporter and checked here: R3 is the OUTCOME rather than the mechanism; K10's bound is inherited from a namespace the reconciler can enumerate; M14's bound is copied from a neighbouring path. This bound is minted fresh from the witness, which is this row.

The mechanism is correct and the record is stale — the exact inverse of R16, where the rule is correct and no mechanism enforces it. Three properties make it expensive rather than untidy: the divergence is created BY the fix, so the moment of error is a moment of success and no author reviews it; nobody edits the record, so it turns false while sitting untouched and every diff-based or authorship-based check is structurally blind to it; and it is detectable only by EXECUTING the register, never by reading it, because a stale item is indistinguishable from a live one by inspection. Separable from C10, where a DESCRIPTION outlives the truth, from R12, where an EXEMPTION outlives its reason, and from A15, where a LEVER outlives its subject: this is an INSTRUCTION outliving its need, and the harm arrives when somebody follows it. analogyThe map still marks the bridge as out, so everybody fords the river. examplebin/gate-ratchet-core.mjs already branched advice on ownsIt while an item described that behaviour as unimplemented; implementing the item as worded would have re-inverted a working guard.

Both statements were true; the accusatory one was the one framed as actionable. 13 files carried the drifted anchors, the session had touched 23 files, and the intersection is empty — the attribution was available in-repo the whole time and the alarm did not consult it before accusing. The gate offered --baseline on every firing, so the correct response was to refuse it roughly forty times, which is indistinguishable from ignoring a real alarm.

WIDENED at edition 17 from attribution comparators to comparators generally: the instrument deciding whether two readings are comparable is itself wrong, whether or not the question is whose a change is. analogyTwo clocks in different timezones are compared by the numbers on their faces. exampleattributeFiles compared git's local-offset %cI against the ledger's UTC Z as strings; re-run through the fixed comparator, 5/12 became 12/12. Second instance, outside attribution, reported 2026-09-06 by the session that made it and then withdrew its own proposal to mint a general frame-mismatch row on finding this one: a process start time in UTC was subtracted from the same process start time in local ACST (+0930), the 9h30m difference was published as "the MCP server restarted mid-session" with a mechanism invented to explain it, and both processes had started at the same instant. It reached a peer fleet plan as stage 1.4 before it was caught; retracted at 4e97f0e. The off-diagonal that forecloses M9 is theirs and is the reason this is not an ambient-environment row: one field is milliseconds and the other seconds, so comparing 1788680976756 with 1788680976 is the same mechanism with ZERO ambient variable, and capturing the environment cannot repair it. The rule is to normalise to base units before subtracting, and to treat "both of these look like times" as insufficient grounds to subtract at all.

Distinct from P13, where the write never reaches the ledger, and from P5, where the instrument misjudges WHOSE a change is: here the instrument is right about the actor and wrong about the subject, so nothing in the attribution layer is faulty and the record is still false. An absence is recoverable by looking elsewhere; a confident wrong name is not, because nothing prompts the reader to look. analogyThe visitor book has a name in it, and it is the wrong visitor. exampletouches.jsonl recorded x:"admin/serve.mjs" for a shell heredoc that edited sitemap/README.md. Grepping the ledger for the five documents that session actually edited returned 0 rows, while the row that did the work pointed at a file it never opened. Second instance, counted and load-bearing: .claude/store/touches.jsonl carried via:"commit" write rows for five filenames (mine.txt, s.sh, new.sh, new.txt, f) that exist nowhere under ~/Repositories at any depth — the basename-collapse hypothesis was tested and refuted. 31 of 31 sessions carried the identical five phantom names, and 1,536 via:"commit" rows hold a bare filename with no directory, mixing genuine root files with these, which is why it read as normal. bin/gate-spine.mjs BLOCKED a session close on the five.

P17closure2gain3	Two identifier spaces in one citation notation	false_provenance.two_identifier_spaces_one_notation	CONTROLLER4 agentunsafecoordination-gapassessed-none	A citation slot accepts tokens drawn from two different identifier spaces with no notational difference between them, so a reference that looks pinned is well formed, unique and still resolves to the wrong actor. Distinct from L8, which needs a CONTENDED identifier: every token here is unique, and the failure sits upstream of contention, in a bracket that disambiguates a name without encoding which namespace its contents belong to. analogyThe catalogue records a shelf number and an accession number in one column. exampleMeasured on this registry. Over the four class text fields, 105 citations carry the agent-ref bracket and 6 classes carry a token that is a transcript prefix in the ref slot rather than an agent ref: C2, A10, D1, D15, M23 and G25. Both remedies proposed for it were withdrawn by their own proposer on measurement, which is why the row exists rather than the fix. Requiring the ref fails because the ref changes on resume: one transcript was recorded as one six-hex ref under pid 94516 on 2026-09-08 and as a different one under pid 59150 on 2026-09-16. Citing the transcript prefix fails because a transcript id is not unique either: on 2026-09-06 one transcript was held by two live processes at once, pids 99699 and 76259, after an editor restart left the old process running, and L8 example already cites the second of them. The surviving remedy is five parts: label which identifier space a bracketed token belongs to; address by the live name plus a ref re-read immediately before sending; correlate across renames by transcript prefix and never address or key ownership on it; use session id, pid and process start together where one identity is needed; and attribute in an example or scoreBasis to the artefact, a sha, a change set or a touch-ledger row, with any session name carried only as a readable label. bin/test/taxonomy-citations.test.mjs now refuses the shape, so this row cannot carry a specimen of it: the row is gated by a test that would reject its own example.

Measured instance caught pre-ship, repo teamDRemote: a count lookup answered a multi-location audience FROM THE PRIMARY LOCATION ALONE. One pick plus a picks array still reads as a valid single-dimension lookup, so the existing guard — which correctly refuses multi-dimension queries because summing would double-count — let it through.

Measured instance in this registry's own read path: the SQLite projection reported 179 classes while the JSON source held 188, in the same minute on 2026-09-02, and the documented `taxonomy-db.mjs --sql` path would have reported nine live classes as absent. It warns loudly when read through the CLI; a consumer piping the JSON or querying the file directly sees no warning at all. Second instance, produced while diagnosing another class: a session read a failure list from a suite run that had started thirty minutes earlier, attributed six dangling import pairs from it, and five of the six had already been repaired by peers before it looked. The downstream cost of that same stale projection, measured rather than predicted: a session reading P4 and M2 through it found them "barer than they are", nearly filed evidence onto rows that already carried instances, and caught it only by re-reading the live JSON. The registry moved 188 to 195 classes in the few hours between one session's first read and the rebuild. Two instances, 2026-09-24. An improvement-loop pass excluded three sitemap backlog items as blocked because their entries read 'depends: B2' and 'depends: B3', while the same backlog recorded B2 and B3 as DONE a few lines above; the dependency note was true when written and was used without re-reading its target, and a review agent caught it.

Measured instance where three readings from one instrument were all internally consistent and all wrong: scrubbing an operator path out of a 39GB reports/ tree, `grep -rlIE` returned 7025 files, exit 0, no warning. A direct find/exec over the same subtree found 1584 history files carrying the path where the recursive grep had accounted for 631 — the instrument saw 40% of that population. A post-scrub run then reported 138 remaining and chain.jsonl: 0 while every one of the 10 chain.jsonl files demonstrably contained the string. Whole-tree undercount unquantified, because no trustworthy total was ever obtained from it. Second instance, a fabricated count from a grafted history: `git rev-list --left-right --count <base>...HEAD` on a SHALLOW clone reported 276 behind where the forge's compare API reported ahead_by=2, behind_by=0 — and the trees were provably identical, `<base>^{tree}` in one clone hash-matching the other clone's `HEAD^{tree}` exactly (651ff292bf846f12436ecf4b214c36dea2f9160b).

The two together are why sweep-health discriminates on pid and not age. Measured instance where the non-completion was structural rather than slow: a wait loop `until grep -qE "Successfully installed\|ERROR" <log>; do sleep 10; done` was backgrounded to wait on a pip install that had been run with `pip -q`, which never emits "Successfully installed". The predicate could not become true for a SUCCESSFUL install — the only exit was the failure branch — and a spinning monitor and a slow install produce identical output, which is silence.

The widest makes working machinery look broken and the narrowest makes a narrow capability look like coverage, and every ratio is true. analogyThe turnout is a triumph or a disaster depending on who counts as invited. exampleThe govulncheck reachability join measured 234 of 11,430 at 2.05% and a far higher figure on the same data on the same day, depending on which dependency population was the denominator. Measured instance: bin/panel-smoke.mjs swept "every visible tab", opened 7, and reported a clean panel. The tab strip is two-level — applyGroup() hides every #views .vtab outside the current section — so a visible-vtab sweep sees one section, and the eleven names it keyed on were SECTIONS, not tabs. Corrected sweep: 77 tabs across 11 sections. 7 of 78 published as the whole panel. c624d17, mechanism at admin/index.html:5160 (groupOf) and :4810 (applyGroup on setView). Cause, from the session that owns the feature: the tabs are SECTION-gated — applyGroup toggles a hide class on every tab outside the current section — so a sweep of visible tabs sweeps one section permanently.

The over-report grows with the population, so a larger subject reads as a worsening crisis. Exact mirror of M19, where the INTERSECTION of two declared-complementary lanes is double-counted; here it is the COMPLEMENT that is falsely counted. Distinct from M18: there is one measurement admitting several denominators there, and two sources joined wrongly here. analogyTwo censuses disagree about a country. One of them only visited the capital. exampleA static dataflow pass reads 965 modules; the runtime pass observes only the 14 that a checked read-only command set enters. Compared naively, an early run scored a directory walk as 2,001 false negatives — the instrument becoming the crisis it was measuring. Separating "path the static pass could have seen" from "path built at runtime" took it to 30, and three further coverage distinctions took it to 0.

Distinct from A22, which is one value with two readers inside one module; this is two producers across a stream boundary.

The document sha changes on any byte edit, so the consumer's differ would have silently failed to re-link across revisions while validating cleanly.

The control and the test are alike in the property that matters, so agreement between them carries no information and absence of difference reads as a finding. analogyThe fire alarm is tested by pressing the button on a second alarm that was never wired to the building. exampleTwo instances the same day, reaching the same place by different routes. BY PLATFORM: testing whether semgrep's "Internal matching error" (36,037 across a 100-repo corpus) was fixed upstream, the reproducer under semgrep/semgrep:latest gave 0 errors against 1 on the host — one sentence from being reported fixed. The positive control, the SAME Docker harness pinned to the known-defective version, also gave 0, because the defect is macOS/arm64-specific and the image is linux. The upgrade zero and the control zero were indistinguishable and only the control was diagnostic; both runs confirmed paths.scanned == ['eslint.config.js'], so neither was a no-files vacuum — the vacuum was one layer further in. BY PROVENANCE: demonstrating a launcher discarding an exit status, the "before" file was copied out of a working tree that sits on the fix branch, so the copy carried the fix. Patched against patched, no difference, and the absence of a difference looked like evidence about the defect. Corrected by taking the file from `git show origin/master:<path>`; cost about ten minutes and one wrong conclusion drafted. THIRD ROUTE, BY A SILENT FAILURE TO ISOLATE, 2026-09-03: to test whether a trufflehog lint failure was pre-existing, `git stash push -- <paths>` was run to strip the branch's changes before re-running. The command failed on argument syntax — "subcommand wasn't specified; 'push' can't be assumed" — the files stayed modified, and the "control" re-ran the branch against itself. It produced results IDENTICAL to the test arm, which is what a genuine pre-existing failure looks like, and the identity was read as confirmation. Caught by printing `git status --porcelain` inside the control and seeing the files still M; redone in a separate worktree at the base commit, where the failures were in fact pre-existing. The first two routes had a control that could not express the failure; this one had no control at all, and the output was indistinguishable. MOVED TO G26 at edition 17: the 2026-09-06 probe broken by the U+2028 it was written to find was filed here and that placement was wrong, as the session that filed it recorded once a second occurrence five days later supplied the separator.

M26closure0gain3	Verification scoped narrower than the claim it supports	false_measurement.verification_narrower_than_claim	CONTROLLER5 oversightunsafecontroller-algorithmassessed-none	A check is run, passes, and is sound — and the proposition it establishes is narrower than the proposition it is then used to support. Nothing in the result announces the gap, because the check did exactly what it says and the widening happened in the reading. analogyThe door is confirmed locked and the claim made is that the building is secure. exampleThree instances, two sessions, one day. A --settings seam was requested, landed and confirmed present, and its arrival was treated as meaning a permission profile could be enforced — but --settings MERGES ("load additional settings from"), so an empty allow list does not displace 1,156 inherited rules and enforcement needs --setting-sources; the check passed on the narrower proposition. A vm.SourceTextModule probe returned 23 correct static specifiers for one file and was asserted to cover "static from, side-effect import, dynamic import() with a literal, export … from, all exact" — the dynamic clause is false by construction, and a peer measuring 50 dynamic imports in the same tree caught it by diffing two extractors rather than trusting the better one. The third is the same shape in the same hour as the first. \| overwatch-layer (reported by reporter #38, own transcript, 2026-08-29 measured / 2026-09-03 filed): claim under verification was 'the sealed deep-link route resolves within a 25s window'; the check run was Chrome --headless=new --dump-dom --timeout=25000, which snapshots at the page LOAD event (~1s) — --timeout caps hangs, it does not extend observation. Four consecutive probes photographed the synchronous cold state and were read as 12-25s state; one diagnostic round was burned on a 'contradiction' that was two truthful photographs of different instants. Instrument-imposed narrowing (flag semantics), not chosen scope — same predicate. Repair landed with the instance: overwatch-layer tools/probe-route.mjs (dd749e2) waits wall-clock then Runtime.evaluates, and its header states the limit the old instrument hid. Fourth instance, another repo (teamD / Portll-teamDRemote, reporter #30, 2026-09-01): `" OR " in filter` was asserted against a freshly built query builder to mean the two picks were joined by OR. It establishes only that the WHERE clause contains that token somewhere, and the pre-existing contactable clause `(email... OR mobile...)` already did. Subject correct, proposition narrower; re-targeting the artefact could not have helped, which is what separates it from M27. FIFTH INSTANCE, and the first with a denominator — the four above have none. Measured 2026-09-07 to 09-09 in commitwork by reporter #3. The check: family VI's within-family cosine (0.017) sits below its similarity to family I (0.020), uniquely among eleven families. The claim it was used to support: family VI is defectively incoherent and should be split, redistributed or renamed. What the check would still permit, and nobody asked: that every other family sits at a similar margin. It does — three hold by under 12%, all eleven hold when measured against the whole register rather than the nearest family, and an INDEPENDENT hand-assigned grouping the metric never sees (the STPA loop) coheres at only 1.14 to 1.40. That control is what does the work: it shows the metric carries no absolute threshold, so "0.017 is low" was never a statement about family VI at all. Three recommendations were withdrawn on it. Ruled into this row rather than minted as "a ranking always produces a worst member" by reporter #40, who supplied the separation this session could not break: the ranking artefact only bites when the ranking LICENSES something, and licensing it is the widening, so M26 accompanies every constructible instance while M26 fires without any ranking at all.

The pass is evidence the change did NOT land, and it is read as evidence that it did. analogyThe rebuilt engine is signed off after a test drive in the loan car. exampleThree instances, two sessions, one day. A container image was rebuilt and tagged latest while the running unit referenced a different tag, so a backward-compatibility check (a known count, BONDI = 9360) PASSED by exercising the three-week-old image; only a NEW-behaviour assertion caught it, production returning 227,567 against an expected 489,616. A registry test suite returned 35/35 and 99/99 green against a worktree copy that did not contain the edit under test, because the tests are structural and pass either way. The purest form: a .replace() targeted a sentence that had not survived an earlier rewrite, matched nothing, and returned the string unchanged — the blob was byte-identical to HEAD, every check passed, and the only thing that surfaced it was the commit tool reporting "landed 1 path(s)" where two were expected.

One key produces an undercount and a misattribution together and neither is visible in the result. Distinct from C4, C29 and C33, whose keys MOVE so that movement reads as a state change: this key does not move at all, and the same input yields the same keys every time. It is simply not unique. analogyThe register keeps one line per surname and the parish holds four families called Smith. exampleMeasured on this registry, 2026-09-11 and re-measured 2026-09-16 with the file unchanged. Over the four class text fields there are 105 occurrences of the agent-citation shape and 24 distinct strings. A census keyed on the matched STRING reported 24 citations of which 2 carried an over-wide ref; the true number of classes carrying one is 6 (C2, A10, D1, D15, M23, G25), because one token occurs in five of them and survived under the id of whichever was scanned last. Four of six classes were invisible in a result that named two, and the same scan reported both a low count and a wrong owner. Re-run keyed per class rather than per string, the population is 6 and no subject is lost. Second instance, another product and another key space: a batched GraphQL gather on 2026-09-15 reused aliases p0 to p7 across 6 batches, so each batch overwrote the last and 8 of 42 subjects were reported.

Both arms run correctly and the difference between them is real; what is missing is any arm in which the subject is absent, so a scheduled job, a background sweep or an already-running process is counted as the effect of the change. analogyThe shop counts the customers the sale brought in and the town holds its market that morning. exampleMeasured twice in commitwork in one week. The first arm pair read 7 against 0 and was reported as proof; cleared and re-run it read 0, 0 and 0, the original 7 having been the scheduled fleet firing inside a 60-second window. Only bracketing with 45-second idle arms produced signal: idle 0, real 7, scoped 0, idle 0. The same mistake recurred two days later on a different path. Second product, and the arm was contaminated by a process rather than a schedule: in memory-layer the embedder auto-selects LM Studio whenever port 1234 answers (memory/mod.rs:669), so a control arm measured 13 failures against 8 on 2026-09-15, and with the embedder pinned to minilm on both arms it measured 8 against 8. The defence is the same in both: a null arm of the same duration, bracketing the measurement.

MEASURED INSTANCE, and the subject is this family. Family VI is the register's only family whose within-family similarity (0.017) is LOWER than its similarity to another family (0.020, to family I), and the lowest of the eleven; the other ten all hold. That single reading is the finding. CORRECTED 2026-09-07, SAME DAY, BY ITS OWN AUTHOR: the two figures first published beside it do not support it. "19 of 25 classes have their nearest wording outside the family" is true and does not discriminate — a majority does in every family but one, from 56% to 100%, and VI's 76% is merely the second highest. "1 causal edge where families I, II, IV and V carry 13, 10, 7 and 11" compared VI against the four densest families only; measured across all eleven, VI's edge density is mid-pack, and families VIII and X carry zero. The diagnosis is unchanged and rests on reading the 25 rows rather than on those figures: the family is named for an ORIGIN where every other is named for a false belief, so its membership test admits almost any row, and six of its classes sit in the oversight loop describing how agents are SCORED rather than what they produce.

No failure resulted — the class names the construction, not an observed miss. Second instance, where the shared derivation is a SPECIFICATION rather than one agent's single pass: an identity scrub built its substitution list from the addresses an operator named, and the check that confirmed completeness was derived from the same list. The corpus also held the bare domain standing alone and a no-dot variant of one address — forms nobody had listed — and both survived. The tracked scrub was reported complete and was not: a generated fixture still carried the domain, committed hours later at ce5ebae. What caught it was an asymmetry nobody designed: the grep alternation happened to include the bare domain while the substitution list held only full addresses, so DETECTION was accidentally broader than REPLACEMENT and four page dumps surfaced through the gap. Had both been the same array — the obvious implementation — the variant would have been undetectable by its own check.

The failure does not merely appear and disappear — it changes OWNER between runs, moving between 'committed and attributable' and 'uncommitted, possibly someone else's' with nothing changed in between. Distinct from G11, where instability corrupts a claim about CAPABILITY from one sample: here the sample is taken twice on purpose and the second reading is the attribution mechanism itself, so the instability is inherited by the answer to 'is this yours?' rather than by the answer to 'does this work?'. Distinct from M2 as well: an M2 fact was true when taken and decayed; this one was never stable at any instant, and re-measuring produces a different owner rather than a fresher one. analogyThe lost-property office decides whose coat it is by asking again tomorrow. example2026-08-29: bin/gate-tests.mjs sorts failures by whether they reproduce in a pristine HEAD checkout, and re-runs to decide. monitor/test/rerollup-identical.test.mjs was measured at fail 1, then 0, then 0 across three consecutive runs of an unchanged tree, and appeared in the working-tree bucket on one firing and not the four before it. monitor/test/write-atomic-concurrency.test.mjs moved between the two buckets across six consecutive firings with HEAD unchanged at 264bce0.

Invisible in the editor and in review; the file reads correctly and behaves differently. C5 covers the consequence — two instruments disagreeing over one input — but attributes it to the READING tool; D4 places the loss in a re-authoring orchestrator; P13 makes tool choice decide apparent AUTHORSHIP. This one makes tool choice decide the CONTENT, at the write actuator. analogyA typesetter silently converting a quoted backslash-n into a line break. exampleAuthoring a module on 2026-09-02, the six-character escape for NUL became a single raw 0x00 on disk. docs/TRAPS.md records 11 tracked sources already carrying one, where grep answers "not found" (exit 1) and git grep answers "Binary file ... matches" (exit 0) — neither gateable.

The instrument does not return a wrong reading: it fails to parse, before measuring anything. The property that earns a row is that the failure recurred after it had been recorded as a warning in the header of the very file it recurred in, so the class survives its own documentation. analogyThe note warning about the smudge is written in the ink that smudges. exampleTwo independent occurrences five days apart in one commitwork file, bin/test/no-nul-bytes.test.mjs. On 2026-09-06 a probe written to find U+2028 and U+2029 across the tree was broken by them: "." in a JavaScript regular expression does not match a line separator, so a String.replace over the probe own source silently skipped exactly the two lines holding the literal characters, the two it existed to find, and left an unterminated regex literal. The reporter separating observation against M25 is that the fixture was faithful and the INSTRUMENT was not, failing in the same dimension as its subject. On 2026-09-11 the non-vacuity control in the same file used the literal character again and produced the same SyntaxError: Invalid regular expression: missing /. Between the two, the first had been written into that file header as a warning. The file now states the rule it has to obey: every pattern is written with a \u escape and never with the character itself. Corpus after repair, gated at c39f943: 1340 tracked text files, U+2028 0, U+2029 0, mid-file BOM 0, C0-except-ESC 0, ZWSP 1.

G27closure0gain3	Lossy transform, structurally conformant	model_generated.lossy_transform_structurally_conformant	IMPLEMENTER4 agentunsafecontroller-algorithmassessed-none	A transform that shortens or rewrites content emits an artefact that parses, conserves its counts and satisfies its format rule, while its meaning is a different claim. Every instrument downstream measures shape, so a faithful shortening and a corrupt one are the same artefact to all of them, and adding checks of the same kind raises confidence without touching the defect. analogyThe editor confirms that every paragraph is one sentence long and returns the manuscript. exampleMeasured in commitwork on a comment-rewriting pass, 2026-09-06 and 09-07. Introduced at 115c9c5 (bin/comment-suggest.mjs, draftTerse via a fit() helper cutting to TERSE_MAX at a word boundary) and removed at 09751c3, which replaces truncation with a void. The pass rewrote 893 files, +4,411 and -17,488 lines. Of about 896 rewritten files exactly 2 failed node --check; the other 99.8% passed the parser, passed the terse-comment scan and passed the per-file restore guard while carrying clauses chopped mid-sentence. Specimens published as valid: "// This file is the git", from a sentence about the git side against commit-phase-core.mjs; "// no clock reaches the output, the page embeds src-sha256, not a timestamp, so two builds". Conservation holds throughout, one comment block in and one out with zero dropped, so a canary binding input count to output count stays green for the whole incident. The gate that accepted the corruption was written by the same hand in the same session: the terse rule asks for one line, at most 120 characters and no history markers, and a clause chopped at a word boundary satisfies all three. The pass was reverted.

Two passes an hour apart returned different verdicts for nine records, moving attribution-wrong from 8 to 21 — same records, same commits, same tool. 67 attribution judgements were retracted rather than left as numbers a re-run would reverse. SECOND STORE, and this one has no mechanism at all: the fleet memory store admits no supersede or tombstone, measured 2026-09-07 by reporter #17 rather than inferred from its API. A durable note recorded a defect mechanism that its own author refuted the same day; the correction could only be FILED AS A SEPARATE RECORD, and three recall queries on the topic returned the original false mechanism and the correction together on every one. So the correction is retrievable ALONGSIDE the refuted claim, never instead of it: a reader taking both is served, a reader taking the top result may get either. That is worse than an unrecorded correction in one specific way the row should carry — a refuted mechanism sitting in a durable store reads to the next reader as corroboration, and appending to it raises the store's apparent agreement with itself.

D8closure1gain3	Receipt without readback	false_durability.receipt_without_readback	IMPLEMENTER4 agentunsafefeedback-incorrectunassessed	A store returns explicit success on write and no later query the writer can construct returns the item. Persisted and unfindable are indistinguishable because the only evidence of durability is the store's own flag. analogyThe courier signs for the parcel and no address holds it. exampleDISPUTED — the opening instance below was re-measured on 2026-09-02 (cc8ec23) and did NOT reproduce: the record reported as unfindable IS in the store (id 77035d6c, 1844 bytes), all five tag routes reported as returning zero rows return five, and the same upsert-and-recall path succeeds end to end. What that re-measurement DID establish is a different defect — a write-size cliff at the default 5s timeout, where 500B and 5000B verify with an id in 1.5-2.3s while 20000B and 40000B return accepted-unverified with a null id at 5029ms and 5059ms, which is the timeout firing rather than the store failing. Whether the original record landed late or was retrievable throughout cannot be distinguished, and "readback is not synchronous" and "the write is unretrievable" are different claims. memory-layer POST /api/remember returns success true and the content is subsequently unfindable via /api/recall. Second instance, in build tooling rather than a store: Gradle `./gradlew dependencies --write-locks` prints BUILD SUCCESSFUL and exits 0 while writing nothing unless dependencyLocking { lockAllConfigurations() } is separately activated. Measured 2026-08-14 in teamA/libs/platform-errors (BUILD SUCCESSFUL in 3s, ls gradle.lockfile → No such file), re-confirmed 2026-09-02, fixed at teamA d0f1a88b, after which the same command produced lockfiles of 121, 81 and 52 lines; 3 of 3 platform libs showed the identical exit-0-no-artifact shape. Third instance, and the one where the readback settled a genuine ambiguity: a 5193-byte handoff upsert returned state="accepted-unverified" with id=null, and the retry returned was_update=true, version=2, storedSha256===contentSha256 — proving the first write HAD landed and only the receipt was lost, so treating acceptance as success would have been right by luck and treating it as failure would have redone stored work. A fourth, dated but not reproduced in isolation: patch(1) against a file whose context had diverged printed "patching file …" and exited 0 while changing nothing (monitor/rollup.mjs, found by a grep count of 0 after the reported success). Fourth domain, deploy tooling, repo teamDRemote: `supabase functions deploy` exited 0, printed nothing and changed nothing — detected only by comparing the deployed version, still v52 and 22 days stale, where a --debug re-run performed the real HTTP PATCH and reached v53. `deno deploy --prod --non-interactive` printed "An error occurred: This command requires interactive input" and EXITED 0, twice consecutively. 4 of 4 deploy/apply invocations in one session, where the outcome was checked independently, disagreed with the reported status at least once. THE VERIFICATION FAILING OPEN IN THE OTHER DIRECTION, measured 2026-09-06 by reporter #18: a write to the fleet memory store returned 200 and the record WAS genuinely stored, while a readback written as String(row.experience) reported NOT FOUND — recall nests the body at row.experience.content, so the naive form stringifies to [object Object] and the comparison can never match. The receipt was honest and the verification lied, reporting data loss that did not occur. This row already holds receipts as unreliable in both directions; this is the readback being unreliable too, which is the half that makes a correct receipt unfalsifiable.

The store is now accurate and the correction propagates to no one, because the record holds no revision history and no reader set, and the corrector sees a clean record and believes the error undone. analogyThe newspaper reprints page one and delivers it to nobody. exampleA corrected claim left no trace of the original, and every reader who had already acted on it was unreachable. Measured instance: a correction owed to another session — retracting a landed claim that the touch ledger is structurally unable to attribute, after a third session established that CLAUDE_PID has been recorded per row since 5296100 — failed delivery with ENOENT on the peer's socket because that process had restarted. The correction reached nobody and survived only because it was written into BACKLOG-commitwork.md at 973b0a9 instead. A second instance the same day, reported rather than measured here: another session could not deliver a retraction of bad touch-ledger figures because the recipient's name had stopped resolving, and filed it to the taxonomy instead. Third instance, in the taxonomy's own curation: a decision that a reporter's proposed class had been FOLDED into an existing row rather than minted — the reasoning they most needed, since it overruled their proposal — could not be delivered. Their socket returned ENOENT (the process had restarted between their message and the reply) and their name no longer resolved to any live session. The decision survives only because it was written into the row's scoreBasis with their attribution before the send was attempted. TWO DELIVERY FAILURES IN ONE SESSION, measured 2026-09-06 by reporter #6: a correction owed to one peer failed with ENOENT on /tmp/cc-socks/2147.sock, and a taxonomy-candidate message to another failed the same way at /tmp/cc-socks/52008.sock. Both survived ONLY because they had been written to durable records first (973b0a9, 17fbcee) rather than retried. Confirmed independently by reporter #3 the same week: a closing message to a peer who had just ended their session returned the same ENOENT, and cost nothing for the same reason. The addressee going away is the COMMON case on this tree, not the exception, which is the argument for the row's remedy: write the correction to the durable store first and treat the message as a courtesy.

The write is authorised, correct for its own purpose, and indistinguishable from any other; the loss is total because uncommitted content exists in no log, and it is invisible to the writer for the same reason. Separable from D6, which is the EXPOSURE — a record living in one tree where git clean and git checkout are named hazards — where this is the EVENT, and the agent is not a named hazard but a colleague doing sanctioned work. Distinct from D9, which states no second party is involved. analogyYou repaint the wall the other decorator has not photographed yet. exampleA favicon .ico holding a peer's uncommitted rebuild was overwritten during an authorised restyle of the same mark.

Second instance, with a measurable outcome rather than only a convention: on 2026-09-02 two overwatch-layer sessions' npm test runs contended on fixed test ports and reporter #37's land attempt was REFUSED by its own pre-commit gate — a serialize-your-gate-runs protocol that nothing declares had to exist, did not, and the second runner went red. 2 incidents in 3 days. The repair was itself the failure shape: the two sessions improvised hold-commits and confirm-when-done in direct messages, a mutual-exclusion protocol that exists only in two transcripts, binds a third party notified individually, and evaporates if either session dies mid-hold. The vscode-skills holds file claims but has no gate-run or commit-window primitive, so the protocol has nowhere durable to live even when both parties want to declare it. Third instance, where the undeclared protocol became a bypass: overwatch-layer's pre-commit hook runs the suite against the SHARED working tree, so one session's uncommitted work vetoes every other session's commit. Measured 2026-09-02 — 976 of 977 tests pass, and the single failure is green at clean HEAD 216dc0b in a throwaway worktree, red only with another session's dirty files present. Three commits then landed --no-verify over it (d3fddc7 by one session naming that exact test, 44e1cd9 and e942994 by another, measurement in the commit messages). Nothing declares who owns a red test in a shared tree, so the de-facto protocol became "everyone bypasses" — the gate ceasing to exist without anyone deciding that. Fourth instance, gate against gate: while one session's pathspec commit ran its pre-commit gate, 216dc0b landed through its own concurrent gate and the first went red on the shared fixed-port fixtures. The serialisation protocol that now exists — hold commits by message — was improvised by the two sessions after paying for its absence.

Distinct from L7: nothing is spoofed and nobody lies — the namespace simply does not distinguish. analogyTwo patients called Maria Silva on one ward, and a correctly written chart. exampleTwo live sessions were both named name-A ([ref-1] and [ref-2]). A verified defect and a verified sha (67d2ebe) were attributed to the wrong one, and a separate session landed a commit into that session's files on an operator-relayed belief that '8d had closed out'. The sha was right; the only broken link was sha-to-name. Second instance, with a denominator and the mint mechanism: one ListAgents call on 2026-09-02 carried two sessions named name-B ([ref-3], [ref-4]) and two named name-C ([ref-5], [ref-6]) — 4 of 25 sessions unaddressable by bare name, deliverable only via the [ref] disambiguator. In the same window a reply addressed to a socket path copied from a live message's from= field failed ENOENT because the peer had restarted, so a working address became a stale one between being offered and being used. The name is minted from a hash prefix, so collision frequency grows with session count and nothing refuses the mint. Third instance, and it breaks the assumption the first two rested on: a session's OWN name changed mid-session. The curating session was reported by ListAgents as name-D [ref-7] (transcript T1) in the morning, recorded that pair in the session roster as instructed, and was reported as name-E [ref-8] (transcript T1) the same day without restarting — while a DIFFERENT session had been operating as name-E [ref-9] (transcript T2) throughout, and is cited under that name in 11 places in this registry. So the name is not merely non-unique across concurrent sessions; it is not stable for ONE session over time, which means it cannot function as an identifier at all. A reader resolving any of those 11 citations today reaches the wrong session. THE MECHANISM, measured rather than inferred: the touch ledger holds 57 rows for that session across 17 hours under two distinct pids, 52008 and 86372. The process restarted; the transcript id did not change and the name and ref both did. So the pair ListAgents reports is PROCESS-scoped, and the socket path is too — a message sent to the old pid's socket after the restart returns ENOENT, which is how two undeliverable replies the same day were produced. What survived every one of those transitions is the transcript id, which is what the touch ledger already keys on: `s` is its first eight characters, unchanged across the restart, the rename and the reference collision. Fourth instance, and the first where the sender followed the prescribed recovery exactly and misdelivered anyway: a socket send failed ENOENT, the sender called ListAgents, read the row "name-E [ref-8]" from the fresh listing, and sent to that name+ref verbatim. It reached the curating session — whose name had been reassigned to name-E by a process restart hours earlier — and not the session the thread was with, which had been name-E [ref-9] (transcript T2) all day. The identifier was unique AT SEND TIME. The contention is temporal: a name is a mutable binding used as a stable address, and the binding moved between thread formation and send. Detection was receiver-side only, as in every instance on this row. THE MIGRATION FORM: the identifier chosen to ESCAPE this row reproduced it, because uniqueness was assumed rather than measured. Measured 2026-09-06 in commitwork by name-F [ref-10] (transcript unresolved). Transcript id dba193dd was held by TWO live workers at once — pids 99699 and 76259, both alive in ps, both holding sockets, both listed by ListAgents as separate peers — after a restart left the old process running. The transcript id had been broadcast fleet-wide as the durable key precisely BECAUSE fleet names change mid-session, which is sound, and its own holder population was never counted before the old key was abandoned. Second instance the same afternoon: bin/session-roster.mjs --record accepted name+ref+uuid while freshness() calls a row live only if its pid still holds a socket, so every row written by the ranked-authoritative source was filed unverifiable on arrival; fixed 7430ee3, which takes a pid and refuses one holding no live socket. Third scheme reported by name-G [ref-11] (transcript unresolved) the same week: the vscode-skills session row, 62 of 222 rows carrying no pid at all and a reaped row describing a live messaging session. Three successive ownership keys, each chosen to escape the previous one's contention, each refuted within an afternoon. What survived needed no identifier: attribute to the artefact.

The address is valid and unique and resolves correctly, so nothing refuses the send, and the reply reaches an actor with no stake in it while the actor waiting on it learns nothing. analogyTwo letters are written at one sitting and each goes into the other envelope, both correctly addressed. exampleMeasured by the sending session from its own transcript, 2026-09-02: a request for a dispatch seam arrived from one socket mid-turn and a taxonomy evidence request from another later in the same working window. Two replies were composed in one turn with both messages in context, and the seam confirmation was sent to the taxonomy requester's socket (msg_id efa8fed2). The recipient had no panel and no involvement, verified against its own touch ledger; the session that had asked for the seam did not learn it had landed until redelivery. \| Sender-side detection mechanism with one measured instance (reporter #38, 2026-09-01→02): where a shared claim registry exists, the sender can self-check before attributing work — query the registry with the dirty set (overwatch-layer: file_owners — git knows the paths are dirty, the vscode-skills knows who claims them, only the join answers whose). Another task holds the path → address that task's session; NO claim → the outbound message must become a broadcast question, never an assertion about the recipient's work. Instance: reporter #41 asked reporter #38 whether vscode-skills test dirt was theirs; the recipient's file_owners query returned no live claim, converting misattribution into 'reads unowned' — the identical query at the SENDING end would have prevented the misaddress. PARTIAL closure only: no-claim ≠ nobody's (overwatch-layer b51bdb0: a claim releases when its task completes and the edit outlives it), so the mechanism is sender-detectable-within-claim-coverage and the residue is exactly the claim-lifetime gap. closure/gain deliberately not changed — curator's call.

It was fixed locally by invoking the tool through an option that disables that default, with "upstream should still hear about it" written into a commit message and an install catalog. The report has not been filed, the workaround is cheap and permanent and invisible, and every other machine installing that pin hits the same abort with no clue it is known. The second: a session hit a stale-projection warning, read the source file directly instead of rebuilding, and named the consequence itself as leaving the trap armed for the next session — which a third session then hit, nearly filing evidence onto rows that already carried it.
