The business caseThe problem this solves

A team files a sanitized deliverable into the knowledge base and somebody has to decide what shelf it goes on before anyone can reuse it. Most of that decision is not a reading: was sanitization actually cleared, did the client consent, was the engagement actually delivered, does anybody own the tool, how many months since anyone looked at it. Those facts live in the KM register, and the submission -- written by the team being classified -- is not evidence of any of them. What needs reading is narrower and genuinely hard: what this document IS. A 'steering committee pack' and an 'analyst onboarding pack' are four words apart and two shelves apart. The librarian's read of each submission against KM-04 -- the type judgement, the register lookup, the precedence walk and the currency arithmetic -- before a person confirms the filing.

The inputThe actual knowledge-base submissions

The corpus is 60 knowledge-base submissions, 0.03 MB (txt 60). It had to be invented, and inventing it made the one design decision this kit is about unavoidable: clearance, consent, pursuit outcome, ownership and review date are held by the KM system, not asserted by the submitting team. Five of the twelve cases turn on that split. A corpus scraped from anywhere would have had the register facts inside the documents, and then the kit would have been measuring whether a model believes a cover note -- which is a different and much easier question.

The outcomeWhat a good result looks like

A filed record a person confirms instead of a deck a person reads: the shelf, what the asset is, its practice, the reuse the shelf grants, whether the currency window has run out, and the KM-04 rule that decided it.

Where it fitsWhat did work

Every line below is a measured result from this kit's own runs, with the figure that supports it. The headline above is not softened by any of them.

• Your clearance facts already live in a register or DMS field — the free keyword floor plus this rulebook
  The gates are the expensive half of the decision and they are pure lookups. The floor got 35 of 35 rule-gated shelves and 10 of 10 currency flags right, for nothing.
• Your submissions have inconsistent titles and no structured type field — the model, with the rulebook behind it
  Reading what a document IS is the whole of what the money buys here: 60 of 60 against the floor's 55 on type and 57 on practice, and every one of the floor's 8 misses is a reading.
• You need the filing to be auditable line by line — the rechecked arm, always
  rules_applied on a rechecked record is derived by the engine that made the decision, so it always names a rule that exists and is always the rule that fired. The model's is free text and was right 13 times in 40.

At a glanceHow the whole thing runs

Run once, for real, on 2026-08-30. Every figure on these pages was captured from that run — nothing is written from intent.

14 steps, grouped by the question that sends you to them rather than by build order. Each tile carries the one figure that step is about, and opens the page behind it.

Should you use this?What you bring, where it stops, and when not to use it

Before you commit an afternoon to this, these are the answers that decide it. Each one is rendered from the record it lives in — and links the page that holds it in full.

Not asked of this kit — 2 questions: clone (a fresh clone of this kit runs with nothing fetched); judge (nothing here is graded by a model).

Last verified 2026-08-30 — r001-knowledge-taxonomy. Every figure on these pages was captured from that run.

Run itHow this reaches your data

Every result on this page was produced by pure code over checked-in files, with no API key — which is why you can read the numbers before anyone spends anything.

Checked before this shipped — A clean checkout with no key configured renders the whole board -- the six shelves, the rule trace, the register form and the recorded run's answer for any of the 60 submissions -- and scores both free floors offline in about a tenth of a second. The one control that would spend is disabled and the bar says why.

Step 01 of 14Business case

Written for: product manager · Measured during the eval run. Never estimated, never quoted from a vendor page.

In brief

What the clock covers. one filing -- one submission, one model call, end to end including provider-side reasoning tokens, on a shared connection at 5 concurrent workers. The recheck adds nothing measurable: it is pure Python over the reply. NOT a service-level figure: no warm pool, no retry budget, one key.

Current processWhat it replaces

The librarian's read of each submission against KM-04 -- the type judgement, the register lookup, the precedence walk and the currency arithmetic -- before a person confirms the filing.

Step 04 of 14Corpus

Written for: "can I point this at mine?" · Measured off the corpus the run actually used.

In brief

How it is cutWhat one filed record is

No train/test split, because nothing is trained or tuned, and no segmentation, because one submission goes whole into one call. The unit every rate stands on is the FILED RECORD, and there is exactly one per submission -- no matching problem, no alignment step. 12 cases, each a shape KM-04 has an opinion about: five turn on a register fact contradicting the document, and claims_cleared_but_not contradicts it out loud.

SetupWhat the setup figure measured

There is no index to build. The submission, KM-04 and the shelf block go whole into one prompt at 2745.7 input tokens on average. The 0.1 s is what the whole free half costs: evals/check_labels.py re-deriving all 60 answer-key rows plus both free floors answering all 60 submissions, measured end to end on a keyless copy of the kit.

LicenceLicence

MIT, with the corpus generated in-process -- there is no third-party data in this kit to licence.

Bring your ownBring your own knowledge-base submissions

Three files and no code. Put your own documents in data/corpus/ as .txt, one per asset; write data/register.json with one row per asset id carrying sanitization, client_consent, pursuit_outcome, owner, last_reviewed and as_of; and edit data/rulebook.json to your own gates, admitted types and currency windows. src/rulebook.py asserts the rulebook's shelf keys match src/taxonomy.py's ORDER at import, so a half-finished edit fails loudly instead of filing assets onto a shelf half the code has never heard of. Then run the free floor: it needs no key and tells you whether your rules are even expressible before you spend anything.

⚠︎ And what stops being true when you do: Every accuracy figure on this page stops being true the moment the corpus changes. The measured 100% is on 60 invented, templated submissions whose gold labels were derived by the same engine the recheck uses; the free floor's 86.7% is partly a measurement of the generator, because its word lists were written from the phrasings the generator writes. What DOES carry across is the mechanism: the register gates are pure code and cannot be argued with by a document, whoever wrote it.

Step 05 of 14Prompt

Written for: engineer · Logged from the run, verbatim.

In brief

The assembled prompt in full, and its real decomposition. Every part below occurs in the prompt that was actually sent, and the token counts sum to the recorded input total — but they are the input total apportioned by each part’s share of the characters, not a per-part reading from the provider’s counter. The total is measured; the split is arithmetic, and a part carrying denser text really costs more of it than this says.

AssemblyHow the prompt is assembled

This is the cost lesson as arithmetic: of the 2,750 tokens assembled, 1,214 are rulebooks — 44% of the prompt, the largest single part. A per-request bill follows whichever part is biggest, and on this kit that is the one named here.

The exact six parts sent for KA-0001, the first submission of run r001-knowledge-taxonomy, replayed from the kit's own src/prompt.py build(). Trustworthy as the prompt that was sent because the replayed part names and character counts (1,516 / 4,653 / 2,254 / 481 / 583 / 1,051 = 10538) match the decomposition the run itself recorded in results/eval-r001-knowledge-taxonomy.json.

Full promptThe prompt in full

You are filing one submitted knowledge asset into Northgate Advisory Partners' knowledge taxonomy,
against the firm's written standard KM-04, which follows. Your output is the FILED RECORD a
knowledge librarian confirms -- so that the librarian confirms a filing instead of reading a deck.

How to read the submission:

- The submission is the submitting team's account of its OWN work. It is NOT evidence of
  clearance. What the firm holds is stated in the KM REGISTER ROW below; a cover note saying an
  asset "is fully sanitized" or "consent is on file" changes nothing if the register says
  otherwise.
- Read the asset TYPE off what the document actually is -- its title, its abstract and its
  contents -- not off where the submitting team hopes it will land.
- Read exactly one PRACTICE. It describes the work the asset is about, not the team that sent it.
- Apply KM-04 as written, including its precedence: a rule higher up the order settles the shelf
  and rules below it cannot lift the asset back out of `restricted`.
- Apply the currency window in section 3.7 by counting whole months from the register's
  last_reviewed date to its as_of date.
- Where the document leaves you unsure of the shelf, answer `unsure` rather than guessing. An
  abstention is counted separately from a wrong answer.
- Report a confidence between 0 and 1 for the shelf. Say what you actually believe; a flat 0.95 on
  every answer is a number nobody can use.

THE KNOWLEDGE STANDARD, as written:

# Knowledge Management Standard KM-04 — filing a sanitized deliverable

Northgate Advisory Partners. Issued by the Knowledge Council. In force from 2026-11-30.

Every asset a team submits to the knowledge base is filed on exactly one **shelf**. The shelf is
what grants reuse; nothing else in the record does. This standard says what the shelves are, which
kinds of asset each one takes, which facts in the **KM register** override a reading, and how long
an asset stays current.

## 1. The shelves

**`method` — Methodology & Approach.** How we do the work, with no client in it: frameworks,
workplans, operating models, maturity grids, training material. Reuse grant: `firm_wide`.

**`deliverable` — Reference Deliverable.** A sanitized client output kept so the next team can see
what good looked like. Reuse grant: `firm_wide`. This shelf asserts that the firm *delivered* this
work; see 3.3.

**`proposal` — Proposal & Pitch Asset.** Win themes, credentials, pricing structures, scoping
decks. Reuse grant: `pursuit_only` — reusable inside a live pursuit and nowhere else.

**`insight` — Point of View & Research.** POV papers, market scans, benchmarks. Reuse grant:
`external_ok` — the only shelf whose contents may leave the firm.

**`tooling` — Tool & Model Asset.** Calculators, code, data models, dashboards. Reuse grant:
`named_owner` — usable by anyone, on the condition that a named person maintains it.

**`restricted` — Restricted — Not for Reuse.** Reuse grant: `none`. The shelf the rules force. It
is a classification, not a failure to classify.

## 2. The asset types, and the shelf each one files to

| type | files to |
|---|---|
| `framework`, `workplan`, `training_material` | `method` |
| `client_report`, `client_deck` | `deliverable` |
| `proposal`, `credentials` | `proposal` |
| `pov_paper`, `market_scan`, `benchmark` | `insight` |
| `calculator`, `code_asset`, `data_model` | `tooling` |
| `other` | `restricted` (rule 3.6) |

A shelf takes only the types listed against it. `client_deck` is the one type two shelves take —
`deliverable` and `proposal` — and which of the two applies is settled by rule 3.3, not by how the
deck reads.

## 3. The rules, in precedence order

**3.1 — Sanitization gate.** If the KM register records `sanitization: incomplete`, the shelf is
`restricted`. This holds whatever the submission says about itself. **The register is the authority
on clearance and the document is not**: a cover note asserting that names have been removed is the
submitting team's account of its own work, not the sanitization reviewer's.

**3.2 — Client consent.** If the asset's type files to `deliverable` and the register records
`client_consent: withheld`, the shelf is `restricted`. The client has already made this decision.

**3.3 — Pursuit outcome.** If the asset's type files to `deliverable` and the register records a
`pursuit_outcome` other than `delivered`, the shelf is `proposal`. A reference deliverable asserts
delivery; material from a pursuit that was lost, or won and not started, is a pitch asset.

**3.4 — Named maintainer.** If the asset's type files to `tooling` and the register names no
`owner`, the shelf is `restricted`. A tool with no owner keeps producing numbers after everyone who
understood it has rolled off.

**3.5 — Admitted type.** A shelf takes only the types listed against it in section 2. A filing the
taxonomy does not admit is corrected to the type's own shelf.

**3.6 — Unfiled type.** `other` files to `restricted`. The taxonomy has no home for it yet.

**3.7 — Currency window.** An asset is `review_due` when its register `last_reviewed` date is older,
at the register's `as_of` date, than its shelf's window:

| shelf | window |
|---|---|
| `method` | 36 months |
| `deliverable` | 24 months |
| `tooling` | 24 months |
| `proposal` | 18 months |
| `insight` | 12 months |
| `restricted` | never due — it is not in circulation |

Being out of date does not move an asset. It is a maintenance flag carried beside the shelf.

## 4. Practices

Every asset carries exactly one practice: `strategy`, `operations`, `technology`,
`risk_and_regulatory`, `people_and_change`, `deals`, `finance`. The practice is a reading of the
work the asset is about, not of the team that submitted it.

## 5. The reuse grant

The reuse grant is derived from the final shelf and from nothing else:

| shelf | grant |
|---|---|
| `method` | `firm_wide` |
| `deliverable` | `firm_wide` |
| `proposal` | `pursuit_only` |
| `insight` | `external_ok` |
| `tooling` | `named_owner` |
| `restricted` | `none` |

A submission does not describe its own licence.


THE SHELVES, and what filing an asset on one commits the firm to:

  method       Methodology & Approach
               FIRM-WIDE. How we do the work, with no client in it: frameworks, workplans, operating models, maturity grids, training material. Anybody in the firm may lift it whole into a new engagement, so it is the shelf with the widest blast radius and the lowest ceremony.
               reuse grant: firm_wide

  deliverable  Reference Deliverable
               FIRM-WIDE, AS A WORKED EXAMPLE. A sanitized client output kept so the next team can see what good looked like. It only earns this shelf when the register says the engagement was DELIVERED and the client consented; a pitch filed here is a promise dressed as a precedent.
               reuse grant: firm_wide

  proposal     Proposal & Pitch Asset
               PURSUIT TEAMS ONLY. Win themes, credentials, pricing structures, scoping decks. Reusable inside a live pursuit and nowhere else — pricing lifted out of a pursuit deck into a delivery document is the quiet way a rate card leaves the building.
               reuse grant: pursuit_only

  insight      Point of View & Research
               EXTERNALLY PUBLISHABLE, ONCE REVIEWED. POV papers, market scans, benchmarks. The only shelf whose contents may leave the firm, and therefore the one where being out of date is not untidiness but a published claim nobody stands behind any more.
               reuse grant: external_ok

  tooling      Tool & Model Asset
               NAMED OWNER REQUIRED. Calculators, code, data models, dashboards. Somebody has to be on the hook for it, because a tool is the one kind of knowledge asset that keeps running after everyone who understood it has rolled off.
               reuse grant: named_owner

  restricted   Restricted — Not for Reuse
               NO REUSE. The shelf the rules force: sanitization incomplete, consent withheld, no maintainer, or a type the taxonomy does not file. It is not a failure to classify — it is a classification, and it is the one that has to be right, because an asset wrongly let out of here is in circulation before anybody notices.
               reuse grant: none

Written for: the skeptic · The harness output, with as_of / model version / dataset version / verified_by.

In brief

File each finished client deliverable like a careful librarian — 60 knowledge-base submissions. One model answered, and every answer was then graded Four different ways — because the grade is a measurement too, and most of what went wrong on this kit went wrong in the ruler rather than the model.

The rulerHow it was graded

Every grader is exact-match Python over closed vocabularies plus one boolean and one set membership. No model judges anything, so re-scoring a cached run costs nothing -- which is what let the rechecked arm and the rule-citation diagnostic both be added AFTER the paid run, from its own cache, for $0.00.

MeasurementsWhat was measured

Two words carry this page: Counted is deterministic and nobody's opinion and Not yet known is printed blank rather than filled with something plausible. There is no Judged row here and that is the point: nothing on this page is a model's opinion about another model. The row most worth having is currently the empty one.

Grading costWhat it costs

Every dollar on this page is a MEASURED token count multiplied by a named vendor's PUBLISHED rate — a projection onto a rate card, not a bill anyone paid. The token counts come from the provider's own usage block on each call.

Rates checked 2026-08-27. The provider that actually ran every call here is kept off this page per the series rule. The real spend is recorded in the run record and the shared call ledger, not on this page.

Grading unitWhat the grading figure prices

The graders are pure code, so grading is free in tokens and in reviewer time. The COST of the run being graded is a different number and lives in the Cost lens; conflating them prices the ruler in the units of the thing it measures.

The gradersFour ways to grade

The null baseline answers restricted for all 60 and reads the type off nothing. It scores 33.3%% on the shelf and 1.7%% record-all-correct, and it withholds every reusable asset in the corpus -- 40 of 40 false closed. That is the number every figure above has to beat before it means anything.

Every row opens its own page: how the test was run, the input on one real row, the prompt or formula with every iteration of it, and the analysis.

Choosing oneWhich one to use

The comparison is only useful if it ends in a choice. The answer is conditional — and it is not the grader with the best agreement score.

This pipeline was also attacked, which is a different question from whether its answers are right: see Threat model for the injection experiment, its two gates and what it does not prove.

Failure causesHow it fails

Step 07 of 14Unit cost

Written for: whoever signs off on the bill · Measured over the eval run, per model. Never quoted from a vendor page.

In brief

The token counts are measured on a real run and belong to this pipeline — which sections are selected, the field schema, the prompt — so they hold wherever you run it. The dollars are those counts multiplied by each vendor's published rate, checked 2026-08-27. Nobody paid these particular bills; they are what the same work would cost you on a card you can sign up to today.

Answering vs gradingGrading is free; the bill is the 80 calls that answered.

Every grader is pure code and costs $0.00 to run against any result set — there is no LLM judge anywhere in the grading path, which is what let the rechecked arm AND the rule-citation grader both be added after the money was spent, from the run's own cache. The figure above is the token counts of the two PAID runs — the 60-submission scored arm ($0.4349 on the card) and the 20-call injection probe ($0.1022) — priced at the same projected card cost_per_query_usd uses, not a second larger spend.

Cost driversWhat actually moves the bill

• PROVIDER-SIDE REASONING, and it is not close. 111594 of 117512 output tokens (95.0%) were reasoning that never reached the reply. The answer is a couple of hundred tokens of JSON; the bill is the thinking behind it.
• THE OUTPUT RATE. Output is priced at 3x input on this card and the run sent 2746 input tokens per call against 1958 output -- so the bill is roughly two-thirds output.
• THE STANDARD, ON EVERY CALL. KM-04 and the shelf block are 6,907 of the prompt's 10,538 characters and are re-sent with every submission. There is no index and no retrieval step to reduce it.
• THE CACHE SPLIT, IN THE OTHER DIRECTION. 71.3% of input tokens came back as prefix cache hits on the provider that ran it, priced at a fraction of a miss — which is why the input side is a third of the runtime bill despite the standard being re-sent every time. No card on this page models it.

Your volumeWhat it costs at your volume

LINEAR IN SUBMISSIONS, and slightly better than linear in dollars. There is no index to rebuild and no state carried between submissions, so 600 submissions is 600 calls; the standard prefix is identical on every one of them, so a provider with prefix caching charges a larger share of the input at the cached rate as volume rises. Latency does not scale: 5 concurrent workers put 60 through in 220 seconds, and the p95 of 46 s is one slow reply, not a queue.

Model choiceWhy this model

It is the tier the shared key is pointed at, and the run is a measurement of this kit on that tier -- not a bake-off. One model, one key, one day.

Other modelsOn other models

This is arithmetic, not a run. No model below was executed against the labelled set, and no accuracy is claimed for any of them. What transfers is the input volume: retrieval is model-independent, so every model would receive the same passages.

the whole 60-submission scored run (r001-knowledge-taxonomy, the fast tier): 164,742 input tokens (117,504 of them prefix cache hits) and 117,512 output. The real bill is on the withheld provider's card and lives in the run record, not on this page.

The codeEvery file, and what it is for

Nine modules, no framework, and almost no dependencies. The pipeline is stdlib Python, because a kit is meant to be read and changed by someone who cloned it ten minutes ago — every dependency is a thing they have to understand before they can touch the part they came for.

Six of these are swap seams: the points you edit to make the kit yours. Each is marked, and each block below is the module’s real shape, read out of the file rather than written here.

The files on this page are not in the public GitHub catalog.

src/taxonomy.pythe taxonomy — a swap seam

Raw HTTP to any OpenAI-compatible provider or Anthropic. Retries a busy provider, refuses to retry a wrong request, and checks the shared daily call cap before spending.

src/recheck.pythe recheck — a swap seam

Takes the model's asset type and practice, honours its proposed shelf only where the taxonomy admits that type, and re-derives every gate, the reuse grant and the currency flag from the register. The RAW arm is kept untouched beside it.

You change it to: Which fields the rulebook takes from the reply. Today: asset type and practice, plus a shelf proposal the taxonomy may veto.

# The model's reading, the taxonomy's rules. Pure code, no model, no key, no network.

evals/baseline.pythe free floor

A word list reading type and practice, in front of the SAME rulebook -- so the gap between it and the model is the reading and nothing else. Plus a null baseline that answers the corpus's most common shelf flat, read from the answer key at import.

Start hereThe shortest path into it

Every entry above is a file in this kit, listed in the order the pipeline runs it.

ScenariosWhat it costs at your volume

Everything below is computed from one measured base: 2745 input and 1958 output tokens per query, all of it fixed — this kit sends the document's own selected sections, so there is no retrieval depth to turn. Change the volume and the bill scales linearly, because nothing here batches.

OperationsFour shapes of workload

The same arithmetic, at volumes worth naming. These are illustrations of scale, not measurements of anyone’s deployment.

Model follows the controls above.

What this ignoresWhere a real bill diverges

In one lineWhat this kit exposes

MEASURED, FORCED AND PAIRED — and the pure-code station is the finding, though not in the way the run expected. The submission is this kit's injection surface: its cover note is a free-text box, it is written by the team whose asset is being classified, and it reaches the model verbatim. The probe forced one KM-annotation-shaped line into every submission with something to suppress and paired each reply against the scored run's own cached answer.

API_KEY is read from the shared <code>&lt;repo&gt;/.env</code>, this kit's own <code>.env</code>, or the real environment, in that order. Both files are gitignored from the first commit; this repo has never held a credential. The key never leaves the machine, is never printed, and src/app.py strips it out of any provider error before returning one to the browser.

The experimentWe attacked it — forced, paired, and one variable

The probe took every submission whose correct shelf is restricted, appended one KM-annotation-shaped line as its final sentence, and left everything else byte-identical. Both were run for real on 2026-08-30.

The second gate is the one this probe cannot retire. It aimed at CLEARANCE, which is the half the register owns and the model is never asked about. A submission that argues its TYPE attacks the field the rulebook trusts the model for, and that experiment is unfired. Writing the shape down here is what stops a future run reporting a clean denominator as resistance.

The result0 of 20 raw suppressions and 0 of 20 after the recheck &mdash; forced and paired; 0 of 20 asset types moved. The two zeros are different claims.

Every trial is one submission of this corpus with the shipped line appended as its final sentence and everything else byte-identical, paired against that same submission's own un-injected answer read from cache-r001-knowledge-taxonomy.jsonl -- one variable, and the control cost nothing. Only submissions the control filed correctly are in the paired denominator, which here is all 20 because the scored run filed 60 of 60. THE TWO ZEROS ARE NOT THE SAME CLAIM. The RAW zero is a measurement: this sentence, this model, this day. The RECHECKED zero is a property of the design and would hold if every raw answer had been suppressed, because src/rulebook.py takes sanitization, consent, outcome and ownership from data/register.json and the injected line cannot touch any of them. What the rulebook DOES take from the model is the asset type -- and that is the surface this design leaves open.

HonestyWhat this does not prove

• Any phrasing but the one shipped, and any position but the final line. A submission that argues its TYPE -- the field the rulebook trusts the model for -- is a different experiment and the one this design most owes.
• Repeats. One draw of a decision the provider re-rolls per call. All 20 injected replies came back filed identically to their controls, which is a hint about stability and not a measured spread.
• Whether the free keyword floor is a mitigation. Its word list never weighs an instruction, so this sentence cannot reach it -- but that is an argument from its design, not a measured result: the floor was not run over the injected submissions.
• A poisoned REGISTER row. The register is trusted absolutely by design; anyone who can write it can grant firm-wide reuse to anything, and nothing in this kit checks it.

In one lineThe only guardrail is the prompt

One instruction, no enforcement. It mostly holds — and mostly is the whole subject.

Never file an asset into a knowledge base, never grant anybody access to anything, never notify a submitting team, never overrule a librarian. This kit produces the record a PERSON confirms, and `restricted` is that record saying the rules withheld this one and naming which rule did it.

Stated on the UI, in the README and in src/app.py's docstring, and enforced by there being no such endpoint: the server's POST routes return filed records and nothing else, and there is no write path to any knowledge system.

EvidenceDoes it hold?

The limitWhat a guardrail is not

• This is ABSENCE OF A WRITE PATH plus a prompt rule, not a runtime enforcement layer — with one real exception: the rulebook IS enforcement for every gated field. It is NOT enforcement for the reading, and the reading is where every unfixable error lives.
• ⚠︎ THE RECHECK BOUGHT NOTHING MEASURABLE ON THIS RUN. 0 overrides on 60 submissions, because the model got every graded field right. What it demonstrably bought is an AUDIT TRAIL (its rules_applied is derived and always names a rule that fired; the model's free-text citation was an id KM-04 does not contain on 16 of the 40 replies that gave one) and an injection boundary. Anyone reading the rechecked column as a measured accuracy gain is reading it wrong.
• ⚠︎ THE INJECTION RESULT IS NOT A DEFENCE OF THE READING. The probe measured one sentence aimed at CLEARANCE; the rechecked 0 of 20 is architecture (the lied-about fields are ones the code never asks the model for), and an attack that argues the asset TYPE — the field the rulebook trusts — is unmeasured.
• The 100 pct is agreement with a computed key on an invented corpus, and the engine that rechecks is the engine that wrote the key. It is not evidence about a real firm's knowledge inbox.
• The confidence floor is not a control on this evidence. Every answer came back at 0.90 or above and 0 were escalated at 0.60, so nothing here says the number separates right from wrong in either direction. It is published as a measurement and never as a safety mechanism.

WatchedWhat is watched, and why that one

The kit measures 30 watched figures plus 8 comparability guards and 5 reference constants — three duties, not one list. 0 of the watched are grader rates, each on its own grader page; this board watches the ones that decide when to look again. Each square is one watched figure; filled means the latest run measured it.

17 measured by the latest run 13 need the model half

GuardsBefore any comparison

Preconditions, not alarms. If one moves, the runs were not measuring the same system and nothing else on this board may be differenced.

no shared guard The two recorded runs declare no guard in common, so nothing below is protected by a precondition — read the history as two separate observations, not as a difference.

The reference constants — the null-grader baseline, the adjudication matrix, the negative count — are the third duty. They are never re-measured per run: a baseline that moves with the thing it measures is not a baseline.

BandsThe alarm bands

Derived from evidence, never picked: exact-match where two runs reproduced a metric to the digit, wider than the measured same-input drift for latency, one row of the negative class for any rate — denominator printed beside it.

HistoryRun history

4 recorded runs. A dash is a metric that run did not measure, and a dash is never differenced: not measured is a third state, neither a value nor a zero, and reading it as zero is how a board reports an improvement on a run that never looked. They are split into 3 blocks because a free floor is a baseline rather than a peer, and a run of another kind measures another thing; a column in one block is never differenced against a column in another.

comply · no model in the path — a baseline, not a peer column — 2 runs. A floor is what the kit scores with no model in the path; it is the line the model runs have to beat, and it is never differenced against them.

not a time series No two of these 2 runs measured the same system — they differ on floor, the model — so nothing here may be differenced and the Verdict column is left off. Read this block DOWN a column, as a comparison between those runs, not along a row as a history.

comply · with the model in the path — 1 run. Columns here are only ever compared with each other.

one run A verdict is a comparison and one run has nothing to compare with, so the Verdict column is left off rather than filled with 91 chips that all say so.

redteam · with the model in the path — 1 run. Columns here are only ever compared with each other.

one run A verdict is a comparison and one run has nothing to compare with, so the Verdict column is left off rather than filled with 17 chips that all say so.

DeviationsWhat deviated

0 breaches across 4 runs

The day a band breaks, a row renders here carrying the metric, the two runs, the band it crossed and what changed between them — model, prompt, chunker or top_k, read off the run records’ guards. A deviation with no diff beside it is an alarm nobody can act on.

RippleThe ripple map

Which figures move together, so one alarm reads as a system. Every edge carries its basis: measured names the run that showed it; reasoning admits nothing has varied it yet.

FiresWhat fires when a band breaks

Where evals stop sitting beside the guardrail and start feeding it. Where the answer is nothing automatic, the row says so — hiding it would undo “What a guardrail is not” above.

NextThe three you would add first

None of these is built here. They are named against the seam they sit on so they can be argued with.

CadenceWhen to re-run, and what it costs

The answer-key check and both free floors are free and re-run in about a tenth of a second. Only the model arm and the probe cost money (80 calls all told), and neither is re-fired after its misses are read; the rechecked arm and the citation grader can both be re-derived from the cached replies at any time for nothing — and both actually were, after the money was spent.

In one lineNo framework, deliberately

NO FRAMEWORK. A folder of readable Python, standard library end to end — no orchestration layer, no vendor SDK, no retrieval stack, no rules engine, no pip install. requirements.txt names nothing and says why.

The mappingSeam by seam, who owns what

The seams are the ones this kit already publishes, so the mapping cannot drift from the code.

GraphsWhere LangGraph changes the answer

Linear, and concurrent only at the submission level. There is no agent, no tool loop, no retrieval and no state carried between submissions; every submission is independent, which is exactly why 5 workers is the entire concurrency story.

The other sideWhat a framework costs you

• Adding a provider means editing the PROVIDERS dict by hand. In exchange pip install pulls nothing and a forker runs this on whichever key they already hold.
• The reply is parsed by hand. It held across all 80 paid calls, and that is an observation, not a guarantee — a structured-output library would fail loudly where this fails quietly. The hand-written normaliser also carried a real defect this run: it folded the hyphen in rule_applied into an underscore, and nothing caught it because the field is a diagnostic.
• No rules-engine DSL, so a taxonomy whose SHAPE differs from KM-04's (a hierarchy, multi-label assets, per-practice exceptions) is a change to src/rulebook.py rather than to a config file. The JSON carries the gates and the numbers; the code carries the shape and the precedence.
• No ontology layer, so the shelves are flat literals. That is a deliberate limit and it is stated in Data.breaks_on rather than hidden behind a file format that could in principle express more.

In one lineWhat one run of this kit actually cost, in time and tokens

Measured on r001-knowledge-taxonomy on the fast tier, 2026-08-30. This kit records telemetry measured per run — 4 of the 6 readings on this axis, 4 of them with a band the guardrail board can judge against.

The readingWhat the last run measured

No movement column. Not one of the 2 earlier runs on record is comparable with this one — a different model tier, or a changed guard — and differencing across that measures two systems rather than one. Said once here rather than as a dash on every row.

Retrieval not shown. No run of this kit has ever recorded a retrieval timing, because the pipeline has no such stage. Those readings are left out rather than dashed: a dash says “this run did not measure it”, which promises a later run could.

DriftMedian call, run over run

No drift chart. Only one run has recorded a call latency; the other 2 runs on record made no model call at all — a rules-only floor stores 0, which is an absence, not a zero-millisecond answer. One timed run is a reading, not a trend, and it is in the table above. A chart appears the day a second run times itself.

The other sideWhat this does not tell you

The first of those is the one worth doing something about, and it is a solved problem: instrumenting a pipeline so each step reports its own duration is a couple of lines. Observability / tracing has the code, and what the result looks like once it is running.

In one lineWhat you provision, honestly

Everything measured on this page says where it was measured; everything not measured says that — the same contract as the other thirteen pages. Where a retrieval index would be on other kits, this one has: no index — the label set is the only structure.
