Can Mistral AI keep a table together across a page break?
Mistral AI handled one cross-page table case and failed another. In the passing case, all 22 rows were recovered across two table blocks, with the repeated page-4 header outside the data and row order preserved. In the failing case, the second page used the first data row as its header, so 25 rows were returned and later rows lost their column labels.

Stations are visited in the order shown wherever the tide allows. Depths are metres below lowest astronomical tide as recorded at installation, and are not corrected for later change.\n\n## The programme\n\nThe water quality programme has run in its present form since 2011, when the first two stations were established at Vardenne Quay and Thrimby Point. There are now twenty-two, the most recent added in November 2025. The programme provides the baseline against which any change at Kellow Sands is measured, and it is the only continuous record of salinity in the upper estuary. Sampling is carried out by the Partnership's own staff, with the Vellamy Society providing cover during August.\n\nAnalysis is carried out under contract by Kirkhollow Analytical Laboratories. The determinations are those set by the 2015 programme review: suspended solids, chloride, ammoniacal nitrogen, oxidised nitrogen, orthophosphate and dissolved organic carbon, with particle size on the intertidal stations twice a year.\n\n## Sampling\n\nSamples are taken from a boat at the deep stations and by wading at the intertidal ones, in each case on the ebb and within two hours of high water. Where a station cannot be reached on the day it is due it is taken as soon afterwards as conditions allow, and the actual date is recorded: the schedule is a plan and not a record. Stations on a weekly interval are the exception, and a missed week there is reported to the Board.\n\nField measurements of temperature and dissolved oxygen are taken at every visit, entered in the field book, and transcribed into the station record within the week. Bottles are delivered to Braithe Road the same day wherever the round permits, and are held in the refrigerated drop box overnight when it does not.\n\n## The stations\n\nGrid references are to the nearest ten metres and describe the position of the marker, not of the sampling point, which at the intertidal stations is up to five metres seaward of it. Two stations are sampled quarterly rather than monthly; both were added to answer a particular question about the southern creeks, and both are due for review in 2027.\n\nAccess is by public footpath at every station except Marnhead Deep and Tarbert Jetty, both of which need the harbour master's permission and a crew of two. The Partnership's insurance covers wading only where a second person is on the shore, and staff are asked not to work the intertidal stations single-handed even where the access itself is straightforward.\n\n## Reporting\n\nResults are entered in the station record within a week of the report arriving from the laboratory, and the record is closed for the quarter at the end of the following month. A late result is entered with the date it arrived as well as the date of sampling, because the two have diverged by as much as five weeks where the laboratory has had to repeat a batch.\n\nThe quarterly summary goes to the Board and to the Harbour Board, and an annual summary is published. Neither includes the field measurements, which are held in the station record and are available to anyone who asks the secretariat for them.\n\nPage 1 of 4", "images": [], "tables": [], "hyperlinks": [], "header": null, "footer": null, "dimensions": { "dpi": 87, "height": 1018, "width": 720 }, "confidence_scores": null, "blocks": [ { "top_left_x": 66, "top_left_y": 45, "bottom_right_x": 297, "bottom_right_y": 59, "content": "Braithe Estuary Partnership \u00b7 Water quality programme", "confidence_scores": null, "type": "header" }, { "top_left_x": 66, "top_left_y": 61, "bottom_right_x": 481, "bottom_right_y": 82, "content": "# Monitoring stations: schedule and sampling intervals", "confidence_scores": null, "type": "title" }, { "top_left_x": 66, "top_left_y": 93, "bottom_right_x": 358, "bottom_right_y": 106, "content": "Water quality programme \u00b7 Schedule current at 1 February 2026", "confidence_scores": null, "type": "text" }, { "top_left_x": 66, "top_left_y": 127, "bottom_right_x": 638, "bottom_right_y": 177, "content": "The schedule below lists the fixed stations sampled under the water quality programme.

The programme has lost three stations since 2011: two at the head of Kellow Creek, which dried out after the storms of 2014, and one at the bar, which could not be reached safely often enough to be worth keeping.\n\nA change to a sampling interval does not need a Board decision and is made by the secretariat where the tide or the staffing requires it. Every such change is listed in the quarterly summary. Two stations moved from monthly to quarterly in 2024 for that reason and both are due to be reviewed.\n\n## Equipment\n\nField measurements are taken with two hand-held meters, both serviced annually under contract and both calibrated against the same standards before each round. The meters are identified in the station record by serial number, because a drift on one of them in 2022 was traced only because the record said which meter had been used.\n\nThe boat is the Partnership's own and is kept at the boatyard. It carries no sampling equipment of its own: everything goes aboard for the round and comes off afterwards, which is slower but has stopped bottles being left in the sun.\n\n## Health and safety\n\nEvery station has a written access note, and the notes are reviewed each January. Two stations need a permit and a crew of two; three are on soft ground where a wading pole is carried; and one, at the training wall, is worked only on a falling tide and never alone. The notes are in the boat's folder and in the office copy of this schedule.\n\nStaff working the intertidal stations carry a radio and tell the office which round they intend to work and when they expect to be off the flats. The office rings the duty officer if a party has not reported in within an hour of that time. The arrangement has been tested twice and worked on both occasions.\n\n## The record\n\nThe station record is a spreadsheet held on the Partnership's own drive, with a copy taken monthly and held by the Harbour Board. It carries one row per visit: the station, the date, the time, the state of the tide, the field measurements, the laboratory reference and the results when they arrive. Nothing is overwritten. A corrected value is entered as a new row with a note, and the original stays where it was.\n\nThe record goes back to March 2011 for the original stations and to the month of installation for the rest. The first two years are less complete than the Partnership would like: the state of the tide was not recorded at all until 2013, and there is a gap of eleven weeks in the winter of 2012 when the meter was away for repair.\n\n## The 2015 review\n\nThe programme was reviewed in 2015 by a panel of three, one of them from outside the estuary, and the review is worth reading before any change is proposed. Its main recommendation, that the number of determinations be cut and the number of visits kept, was accepted; the programme has been cheaper and more useful since. Its second recommendation, that the Partnership publish the data as it is collected rather than annually, has not been implemented and is raised at most Board meetings.\n\nThe panel also recommended that two stations be moved: one at the head of Kellow Creek, which was moved forty metres seaward in 2016, and one at the bar, which was withdrawn instead. The reasons for withdrawing rather than moving it are in the minute of that meeting and are still sound.\n\nPage 2 of 4", "images": [], "tables": [], "hyperlinks": [], "header": null, "footer": null, "dimensions": { "dpi": 87, "height": 1018, "width": 720 }, "confidence_scores": null, "blocks": [ { "top_left_x": 66, "top_left_y": 44, "bottom_right_x": 296, "bottom_right_y": 59, "content": "Braithe Estuary Partnership \u00b7 Water quality programme^{}[] ---", "confidence_scores": null, "type": "header" }, { "top_left_x": 66, "top_left_y": 76, "bottom_right_x": 200, "bottom_right_y": 93, "content": "## Changes to the schedule", "confidence_scores": null, "type": "title" }, { "top_left_x": 66, "top_left_y": 97, "bottom_right_x": 654, "bottom_right_y": 163, "content": "A station is added or withdrawn only by a decision of the Board, on a recommendation from the secretariat, and the reason is minuted.

Braithe Estuary Partnership · Water quality programme # Monitoring stations: schedule and sampling intervals Water quality programme · Schedule current at 1 February 2026 The schedule below lists the fixed stations sampled under the water quality programme. Stations are visited in the order shown wherever the tide allows. Depths are metres below lowest astronomical tide as recorded at installation, and are not corrected for later change. ## The programme The water quality programme has run in its present form since 2011, when the first two stations were established at Vardenne Quay and Thrimby Point. There are now twenty-two, the most recent added in November 2025. The programme provides the baseline against which any change at Kellow Sands is measured, and it is the only continuous record of salinity in the upper estuary. Sampling is carried out by the Partnership's own staff, with the Vellamy Society providing cover during August. Analysis is carried out under contract by Kirkhollow Analytical Laboratories. The determinations are those set by the 2015 programme review: suspended solids, chloride, ammoniacal nitrogen, oxidised nitrogen, orthophosphate and dissolved organic carbon, with particle size on the intertidal stations twice a year. ## Sampling Samples are taken from a boat at the deep stations and by wading at the intertidal ones, in each case on the ebb and within two hours of high water. Where a station cannot be reached on the day it is due it is taken as soon afterwards as conditions allow, and the actual date is recorded: the schedule is a plan and not a record. Stations on a weekly interval are the exception, and a missed week there is reported to the Board. Field measurements of temperature and dissolved oxygen are taken at every visit, entered in the field book, and transcribed into the station record within the week. Bottles are delivered to Braithe Road the same day wherever the round permits, and are held in the refrigerated drop box overnight when it does not. ## The stations Grid references are to the nearest ten metres and describe the position of the marker, not of the sampling point, which at the intertidal stations is up to five metres seaward of it. Two stations are sampled quarterly rather than monthly; both were added to answer a particular question about the southern creeks, and both are due for review in 2027. Access is by public footpath at every station except Marnhead Deep and Tarbert Jetty, both of which need the harbour master's permission and a crew of two. The Partnership's insurance covers wading only where a second person is on the shore, and staff are asked not to work the intertidal stations single-handed even where the access itself is straightforward. ## Reporting Results are entered in the station record within a week of the report arriving from the laboratory, and the record is closed for the quarter at the end of the following month. A late result is entered with the date it arrived as well as the date of sampling, because the two have diverged by as much as five weeks where the laboratory has had to repeat a batch. The quarterly summary goes to the Board and to the Harbour Board, and an annual summary is published. Neither includes the field measurements, which are held in the station record and are available to anyone who asks the secretariat for them. Page 1 of 4 Braithe Estuary Partnership · Water quality programme--- ## Changes to the schedule A station is added or withdrawn only by a decision of the Board, on a recommendation from the secretariat, and the reason is minuted. The programme has lost three stations since 2011: two at the head of Kellow Creek, which dried out after the storms of 2014, and one at the bar, which could not be reached safely often enough to be worth keeping. A change to a sampling interval does not need a Board decision and is made by the secretariat where the tide or the staffing requires it. Every such change is listed in the quarterly summary. Two stations moved from monthly to quarterly in 2024 for that reason and both are due to be reviewed. ## Equipment Field measurements are taken with two hand-held meters, both serviced annually under contract and both calibrated against the same standards before each round. The meters are identified in the station record by serial number, because a drift on one of them in 2022 was traced only because the record said which meter had been used. The boat is the Partnership's own and is kept at the boatyard. It carries no sampling equipment of its own: everything goes aboard for the round and comes off afterwards, which is slower but has stopped bottles being left in the sun. ## Health and safety Every station has a written access note, and the notes are reviewed each January. Two stations need a permit and a crew of two; three are on soft ground where a wading pole is carried; and one, at the training wall, is worked only on a falling tide and never alone. The notes are in the boat's folder and in the office copy of this schedule. Staff working the intertidal stations carry a radio and tell the office which round they intend to work and when they expect to be off the flats. The office rings the duty officer if a party has not reported in within an hour of that time. The arrangement has been tested twice and worked on both occasions. ## The record The station record is a spreadsheet held on the Partnership's own drive, with a copy taken monthly and held by the Harbour Board. It carries one row per visit: the station, the date, the time, the state of the tide, the field measurements, the laboratory reference and the results when they arrive. Nothing is overwritten. A corrected value is entered as a new row with a note, and the original stays where it was. The record goes back to March 2011 for the original stations and to the month of installation for the rest. The first two years are less complete than the Partnership would like: the state of the tide was not recorded at all until 2013, and there is a gap of eleven weeks in the winter of 2012 when the meter was away for repair. ## The 2015 review The programme was reviewed in 2015 by a panel of three, one of them from outside the estuary, and the review is worth reading before any change is proposed. Its main recommendation, that the number of determinations be cut and the number of visits kept, was accepted; the programme has been cheaper and more useful since. Its second recommendation, that the Partnership publish the data as it is collected rather than annually, has not been implemented and is raised at most Board meetings. The panel also recommended that two stations be moved: one at the head of Kellow Creek, which was moved forty metres seaward in 2016, and one at the bar, which was withdrawn instead. The reasons for withdrawing rather than moving it are in the minute of that meeting and are still sound. Page 2 of 4 Braithe Estuary Partnership · Water quality programme ### Access to the data The record is available to Partnership members on request and to anyone else at the secretariat's discretion, which in practice means that a request from a school, a consultant or a neighbour is met, and that a request with no reason given is asked for one. There is no charge for a copy of the record; there is a charge for the secretariat's time in extracting something particular from it. The annual summary is published in April and is sent to the parish councils, the wildlife trust and the two angling clubs. It carries the means and the ranges by station and by quarter rather than the individual results, which is a decision of the Board and not a limitation of the record. ### Costs The programme costs about nineteen thousand pounds a year, of which the laboratory's charges are rather more than half and the rest is staff time, the boat and the meters. The Partnership meets two thirds and the Harbour Board one third under the agreement of 2015, which runs to 2027 and is due to be renegotiated in the coming year. ### Determinations Every visit produces a sample for suspended solids and chloride. Ammoniacal nitrogen and oxidised nitrogen are taken at the twelve stations above the training wall, orthophosphate at the six in the creeks, and dissolved organic carbon at four stations chosen in 2015 to give a spread across the estuary rather than a concentration in one reach. Particle size is taken twice a year at the intertidal stations and is the one determination the programme has kept against advice. The 2015 panel thought it of little value at this frequency and the Partnership has continued it because the intertidal survey needs a comparison, which is a reason the panel did not have in front of it.

Why this result
The cross-page table was checked across the page break. Mistral returned 22 rows across two table blocks, kept the repeated page-4 header out of the data, preserved row order, and matched the source rows and cell values.
Also observed on this row
Two table blocks. The product split the continuation into two table blocks. Joining them yields the 22 rows, but the result is not literally one table.
Header artifact. A stray horizontal rule appears attached to the running header.

Braithe Estuary Partnership · Water quality programme Page 1 of 2 ## Sampling visits, winter 2026 Water quality programme · Visits between 6 January and 19 February 2026 Table 2 lists every sampling visit made in the first seven weeks of 2026. A visit is one boat or wading call at one station on one morning; where a station is visited twice in the period it appears twice. Determinations are those taken on the visit, not those scheduled. Times are the time the sample was drawn. Method. Each visit follows the written access note for the station. Field measurements of temperature and dissolved oxygen are taken first and entered in the field book; the bottle is then filled below the surface, labelled with the station code and the time, and placed in the cool box. Where the tide prevents a wading station being reached within two hours of high water the visit is recorded as missed and the next scheduled visit is not brought forward. Samples are delivered to Braithe Road the same day and held in the refrigerated drop box overnight where the round permits. Record. The table below is transcribed from the field books for the period and checked against the laboratory reception log. A visit appears once per station per morning. Determinations are those actually taken, which may differ from the schedule where a meter was out of calibration or a bottle was lost; the two such cases in this period are noted in the quarterly summary and not in this table.

Expected vs. Found
| ✗ | Expected: 26 data rows.Found: 25 rows were returned, with V-15 used as the second block's header. |
| ✗ | Expected: V-15 with its listed visit details.Found: V-15 appears only as the page-2 header line, not as a data row. |
| ✗ | Expected: V-22 with its listed visit details.Found: V-22's values match the source, but they sit under V-15's data. |
| ✗ | Expected: V-26 with its listed visit details.Found: V-26's values match the source, but they sit under V-15's data. |
| ✗ | Expected: V-14 appears before V-15 across the page break.Found: V-15 is not a data row; the next data row after V-14 is V-16. |
| ✗ | Expected: Every page-2 row must still be attributable to its columns.Found: The page-2 rows sit under V-15's data, so their columns are not attributable. |
| ✓ | Expected: Page numbers and the running header stay outside the tables.Found: Those lines appear only as standalone paragraphs between the two blocks. |
Why this result
The cross-page table was checked on the winter visits PDF. Mistral returned 25 data rows, using V-15 as the second block's header instead of a data row, so later rows lost their column attribution and the break order failed.

How this scenario is graded
How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.
How results are decided
Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.
The rules
- Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
- Fail: at least one expected behaviour clearly didn't happen; the row says which and quotes the tool.
- Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the row says what's missing.

Act on this result
Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.
This matches what I see
You run the same kind of test against your own setup and get the same behaviour.
Agree →This does not match
Yours behaves differently. Tell us what you got, with a screenshot if you have one.
Disagree →Point out an issue
Something here is wrong — a reference value, a transcription, a grade.
Report an issue →We have fixed this
Tell us what changed and we schedule a rerun of the failing test case. The old result stays as history.
Vendor notice →Filed against this evidenceNothing yet. Challenges, counter-evidence and fix notices appear here with their outcome, and stay on the page after they are resolved.
