# Holdings census executive report

Domain **bocg**, run `20261016T060747Z`, 4 roots. Counts and digests only; detail tables stay in the run directory.

## 1. Headline

The roots hold **17,501 distinct units** and **33,916 unique spans**. In-domain text outside the already-measured base comes to **2,901,068 words**, which the measured anchor turns into **609 raw episodes, 304 ratified** after adjudication survival, at about **43.5 SME hours**. The structural count from the span ledger is **1,233 candidate spans in 183 episode-shaped components**; the two readings should be reconciled by the blind sample, not averaged.

| measure | value |
|---|---:|
| distinct units | 17,501 |
| unique spans | 33,916 |
| in-domain words outside the measured base | 2,901,068 |
| raw episodes (word-anchored) | 609 |
| ratified episodes (x survival) | 304 |
| candidate spans (structural) | 1,233 |
| episode-shaped components | 183 |
| SME hours at the measured throughput | 43.5 |

## 2. What is on the machine

Documents counted but not read: 1,407. Bulk text units above the segmentation cap hold 3,355,180 in-domain words that do not count until segmented.

## 3. What can be assigned

Time: of 33,916 unique spans, **35% are dated in place** (a date in the span or its message header), **7% are assignable** by inheritance from a dated neighbour, thread or file name, and **58% cannot be dated** from content. Precision: {'day': 12991, 'None': 19794, 'year': 936, 'month': 195}.

Institution: **12% assigned** by declaration, **0% assignable** from mail domains, **88% unassignable**. Institutions seen: 4.

## 4. What links

Link degree over unique spans: 23,607 isolated, 4,092 with one or two links, 3,345 with three to nine, 2,872 with ten or more. 26,279 components, of which **408 are episode-shaped** (two or more spans, two or more dated days, a decision). Component size bands: {'0': 23607, '10+': 221, '1-2': 1785, '3-9': 666}.

## 5. What it would yield, by SKU

Probabilistic, in SKU order. Expected counts over candidate spans with Poisson 95% intervals; base rates anchored on the measured stratum, structural weights declared, survival measured.

| SKU | expected | 95% interval | ratified (x survival) | spans with mass |
|---|---:|---|---:|---:|
| trace | 108.0 | 87.7 to 128.4 | 54.0 | 3,781 |
| episode | 671.6 | 620.8 to 722.3 | 335.8 | 3,487 |
| outcome | 142.6 | 119.2 to 166.0 | 71.3 | 3,487 |
| atom | 3137.9 | 3028.1 to 3247.6 | 1568.9 | 3,781 |

Base: 2,376 spans in the measured base carry the anchor counts {'trace': 62, 'episode': 321, 'outcome': 56, 'atom': 2348}; provenance {'base_rate': 'anchored', 'weights': 'finger_in_air', 'survival': 'measured (click adjudication 10/20)'}.

Word-anchored cross-check and structure:

Word-anchored: 609 raw / 304 ratified episodes, 4,453 atoms, 106 consequential threads, 43.5 SME hours. Structural: 1,233 candidate spans (201,283 words) in 183 episode-shaped components. Complexity of unique spans: 29,267 low, 4,188 medium, 461 high (mean score 0.62).

## 6. Quality and risk

- Duplication across spans: {'unique': 33916, 'exact-duplicate': 4308, 'near-duplicate': 4227, 'boilerplate': 3199, 'quoted-reply': 2440}. Unique share 71%.
- Chunking: words per span p10/p50/p90 41/178/317; spans per unit p50 2.
- Vocabulary terms excluded as generic in this run: office.
- Unread material: 1,407 documents; 3,355,180 bulk in-domain words awaiting segmentation.
- All magnitudes are planning figures anchored on one measured stratum. Everything censused is calibration base, never product.

## 7. Change since the previous run

Previous run `20261016T053121Z`: 0 units added, 0 changed, 0 removed; in-domain words +0; raw episodes +0.

## 8. Decisions needed

1. Adjudicate the blind sample so the structural and word-anchored readings are replaced by a measurement for the mailbox stratum.
2. Decide whether bulk text units are segmented (they hold in-domain words that currently count for nothing) or excluded by rule.
3. Decide whether the unread documents are worth text extraction, given their era and count.
4. Confirm the institution declarations in the config; unassignable spans cannot be sold as any institution's calibration base.
