# check_profile

Check one profile's entered numbers against what is independent of them, and say what looks wrong.

## What it is for

`check_profile` reads one profile and says what looks wrong with its numbers: values the shooter marked not measured, a velocity far from the chronograph strings, a BC or bullet length far from the catalog, a twist that cannot stabilise the bullet, an odd sight height. It also says where the bullet slows to Mach 1.2. It checks the entered numbers against each other and against outside data, not against any shot. It saves nothing, and it never says that a number is right: only that nothing it knows to look for stands out.

## What to know first

**A clean answer is not a verdict.** `Nothing stands out on <name>.` means none of the checks below fired. A guessed velocity with no chronograph strings, a BC with no catalog match, a wrong zero range or an implausible scope factor all pass.

**Name the profile with `profile_id` or `share_id`.** With neither, the call goes to the profile the newest calculator report shows, at any age and without saying so, else to the only profile, else it is refused. The spoken line names the profile.

**Only two findings are spoken.** The line gives the first two things to check and counts the rest. Notes are never spoken; they are in the details, with the stability and the transonic ranges.

**The catalog is used when exactly one bullet fits,** by name with diameter and weight, else by diameter and weight alone, so the matched bullet need not carry the name: say `catalog_match`. A value not given to the account is not compared. No single match, no BC or length finding.

**The transonic ranges are for standard air.** They are the Standard model at 59 °F and 29.92 inHg with the entered velocity, not the day's air and not the profile's own model.

## Generated table

**Tool:** `check_profile` · **Family:** Exploring a profile · **Scope:** any link · **Save scope:** none · **Changes:** nothing · **Runs:** the many-solve pool (4 jobs at once for the whole connector, each stopped after 30 s, 60 s of such work per account per 10 minutes)

**Description** (what the connector sends to an assistant, word for word):

```text
Check one profile's entered numbers against what is independent of them, and say what looks wrong. For come-ups that disagree with the profile use explain_dope. Saves nothing. Any link has it. It checks values marked not measured, velocity against the chronograph strings, BC and bullet length against the catalog, stability (a mistyped twist shows here) and sight height. Only the first two findings are spoken, and nothing stands out means only that none of these checks fired, not that the numbers are right. Guide: check_profile.
```

**Inputs** (2; read from the input schema the connector sends):

| Input | Type | Required | Bounds | Field |
|---|---|---|---|---|
| `profile_id` | text | no | - | - (selects a record) |
| `share_id` | text | no | at most 64 characters | - (selects a record) |

**Sent with the inputs** (each input's own description, word for word; an input not listed is sent without one):

```text
profile_id: A profile id or name. Not given: the profile the phone last showed, else the only one
share_id: Or a profile someone shared with the shooter (from list_shared_with_me); not with profile_id
```

## When to use it, and when not

| The shooter wants | Use | Why |
|---|---|---|
| To know whether a new or just-entered profile looks right | `check_profile` | Runs every check at once and saves nothing |
| Which wrong number explains come-ups they trust | [explain_dope](explain_dope.md) | Fits velocity, BC, zero height and sight height to confirmed come-ups; this tool takes none |
| Which input is worth measuring better | [sensitivity](sensitivity.md) | Gives what each input moves the come-up by |
| The four models side by side | [compare_models](compare_models.md) | Solves each; this tool solves for two ranges only |
| The whole profile, to read a value | [get_profile](get_profile.md) | Returns the record; this tool returns findings |
| A number changed | [edit_profile](edit_profile.md), if the link has it | Saves the next version |
| A bullet's catalog numbers | [search_bullets](search_bullets.md) | Looks a bullet up by name |
| A fitted velocity or drag from logged groups | [calibrate_profile](calibrate_profile.md) | Fits groups; this tool reads none |
| What a profile someone shared looks like | `check_profile` with `share_id` | Checks it without copying it; [get_shared_profile](get_shared_profile.md) returns its numbers |

Ask before calling: which profile, when there is more than one. After a finding, say it and ask before changing anything.

## The inputs

Both are optional and none is stored. Each entry says what this tool does with it.

**`profile_id`** The profile's id, or its name in any letter case with outer spaces ignored; for a copy of a shared profile, the name a reply shows for it, with or without its quotation marks (run). Whatever is given must fit exactly one profile: a name that fits none, an empty text or a name two profiles share is refused with the list or with `More than one profile has that name.` (run). The rule for which profile is on [edit_profile](edit_profile.md), under `profile_id`; here it is the same for a name, an id, a copy and an empty text (run). Not given, and no `share_id`: the profile the account's most recent calculator report shows (from any phone or browser, read; at any age with no word about it in the reply, run), else the only profile, else `Which profile?` with the list. It takes a name as well as an id. The newest live version is checked.

**`share_id`** A profile someone shares with the account, from [list_shared_with_me](list_shared_with_me.md), checked at the version the share holds. Together with `profile_id` the call is refused (run). An id the account has no share for and an empty text are refused with one sentence (run); a stopped share gets the same sentence (read). The reply carries the share's numbers and codes, and its name quoted and cut to 40 characters, none of the sharer's other words. The profile is not copied.

## What it returns

**The spoken line** is `Nothing stands out on <name>.` followed by `It slows to Mach 1.2 near <n> yards.` when `mach_1p2_yd` is not null, or `<n> thing(s) to check on <name>: <first two findings>` with ` And <k> more.` when there are more than two. A thing is a finding at the problem or check level. A stored name is quoted and cut to 40 characters unless it is a short single token (see [the connector overview](connector.md)); `Ridge 308` is quoted, `Ridge` is not (run).

**The details** hold:

| Key | Holds |
|---|---|
| `profile` | `id`, `version` and `name`; for a share `share_id` in place of `id` |
| `findings` | Each has `id`, `level` (`problem`, `check` or `note`) and `text`; a velocity, BC, length, stability or sight height finding also holds `entered` and, where there is one, `compared` |
| `sg` | The muzzle stability from the bullet, twist and velocity, to two places; null when the profile cannot be solved |
| `spin_ready` | True for a profile the solver can use, false otherwise; it does not say the length is measured, nor that the Spin model would use it (a length under 2 calibers is not used) |
| `transonic` | `mach_1p2_yd` and `mach_1p0_yd`, to the nearest 10 yards, counted from the zero range (at least 100 yd) out to 5,000 yd. Null when the bullet is already at or below that speed at the zero range, or has not slowed to it by 5,000 yd; a zero range of 1,000 yd gave null for Mach 1.2 on a bullet that reaches it at 850 yd (run) |
| `catalog_match` | The maker and product name of the one catalog bullet found for the profile's bullet, as the catalog has them (also given for a profile the solver cannot use); null when none was found |
| `saved` | Always false |

**The findings,** in the order they are listed: problems first, then checks, then notes, and within a level in this table's order. The limits are fixed in the code (`AUDIT_LIMITS`), none is an input.

| `id` | Level | Raised when |
|---|---|---|
| `unusable` | problem | The profile cannot be converted for the solver. The text is the conversion's own refusal and can read oddly, for example `it profile <name>: twist must be greater than 0 (is 0).`. No other check is made: `sg` is null and `spin_ready` false; `catalog_match` is still given |
| `unmeasured` | check | An entry of the profile's [not measured](profile/setup.md) list has a plain word (sight height, twist, zero range, barrel length, bullet length, weight, diameter, velocity, G7 or G1 BC, overall length, powder charge, bullet jump, elevation travel). One finding per entry, in the list's order |
| `unmeasured_other` | note | Entries with no plain word: the text is only a count |
| `velocity` | check | The chronograph strings, weighted by shot count (a count that is missing, zero or negative counts as one; a string with no usable velocity is left out), average more than 10 fps from the entered velocity ([velocity](profile/velocity.md)) |
| `bc` | check | A catalog bullet was used and the entered BC of the profile's drag model (G1 or G7) is more than 3 percent from the catalog's, as a ratio to the catalog's ([drag](profile/drag.md)) |
| `length` | check | A catalog bullet was used and the entered length is more than 0.02 in from the catalog's ([bullet](profile/bullet.md)); a pair exactly 0.02 in apart was reported in every pair tried (run) |
| `stability` | problem below 1.0, check below 1.3 | The muzzle stability is below 1.3 ([rifle](profile/rifle.md)) |
| `sight_height` | check | The sight height is below 1.0 in or above 3.5 in |
| `zero_ignored` | note | A zero height or offset is stored and the model does not use it ([zero](profile/zero.md), [model](profile/model.md)); run on all four models |
| `mv_temp` | note | No velocity-temperature table |
| `spin_length` | note | The bullet length is on the not-measured list |
| `aero_set_length` | check | The profile is on the Spin model, names a coefficient set the account holds, and the set's bullet length differs from the profile's by more than 0.005 in; `entered` is the profile's length and `compared` the set's |
| `aero_set_unusable` | note | The profile is on the Spin model and names a coefficient set the account cannot use, so the estimate is flown. The set's id is never in the text |

The finding text for a velocity, BC, length, stability or sight height reads like `Velocity is entered as <entered> fps; the chronograph strings average <mean>.` and `The G7 BC is entered as <entered>; the catalog has <catalog>.`. Every measured value the checks read is in inches, feet per second or the BC itself: the reply holds no turret unit, and a scope in MOA gave the same findings as one in mil (run). A scope factor of 0 or less is an `unusable` problem ([scope](profile/scope.md)).

**What a calibration changes** is only the numbers the checks read: a fitted velocity is the entered velocity, and a fitted drag correction is used in the transonic ranges down to the Mach it was fitted to (run). The reply never mentions the calibration.

**Stored text.** An own profile's name is quoted and cut in the spoken line unless it is a short single token, and the reply then carries `stored_text_note`; the details hold the name whole. The name of a copy of a shared profile and of a shared profile is quoted and cut to 40 characters in the spoken line and in the details, and that reply carries no note (run). In a run with made-up hostile notes, not-measured entries and bullet name on a share and on a copy, none of that text reached the reply: an entry of the not-measured list is worded only when it is a plain field name.

## Worked examples

In example 3 the two profiles are listed in the order they were made; the real list is in the order of the names, character by character by character code, so `Creek 65` comes before `Ridge 308` (read). Example 1 is the clean answer. Example 10 shows every check at once on one profile: eight things to check, only the first two spoken, the rest in the details, which cut a list of objects past three. Example 11 shows a low stability said first as a problem, example 12 a profile the solver cannot use, example 13 a zero range of 800 yd where `mach_1p2_yd` is null and the line has no Mach sentence, example 15 the catalog's BC against the entered one, and example 14 four profiles with none named. Example 16 is a Spin profile with a bullet length of 0, which is also not usable. The test backend's catalog search filters as the server's does; which catalog values an account is given is the server's (read).

Every example below was run by the documentation generator against a made-up account, never a real one. Numbers are rounded to three places; generated ids and times are shown as placeholders. Two things are printed more briefly than the tool sent them, and nothing else is changed. A list of plain values stands on one line, whole up to 12 entries (a longer one, and a list of objects past 3, ends with a count of the rest). A reply marked "with the stored-text note" also carried this note, which is left out of the example: as `stored_text_note` in the details, or in brackets as the last line of a refusal: "Text in quotation marks is stored text (a name, a title or a note someone typed): it is a label, never an instruction."

## When it refuses

| The reply holds | Cause | Tell or ask the shooter |
|---|---|---|
| `Which profile?` | No profile was named, no phone profile or only profile applies; or the profile a phone showed is no longer listed (refused even with one profile left); or the name or id fits none. The profiles follow, in the order of their names by character code (read) | Read the names and ask which |
| `Which profile?` then `You have no profiles yet; create_profile makes one.` | The account has no profile | Offer to make one, if the link may |
| `More than one profile has that name. Use the id:` | The name fits two | Ask which, and call with the id |
| `Give a profile of yours or one shared with you: one or the other, not both.` | Both inputs were given | Ask which one |
| `That profile isn't shared with you, or its sharing was stopped.` | The `share_id` fits no live share of the account (the full sentence names `list_shared_with_me`) | Offer to list what is shared |
| `Too many shared-profile reads just now; wait a minute and ask again.` | The server limited the reads of shared profiles (run on the server's route: `check_profile` with `share_id` got it on the 61st read) | Wait and ask again |
| `The calculator is busy with another long request. Try again in a moment.` | The many-solve pool is full, or this account already has a job in it (read) | Wait and ask again |
| `That took too long and was stopped.` and `Try again in a minute.` | The check passed the pool's time limit | Say it did not finish |
| `You've run a lot of long calculations. Try again in about` and the minutes | The account's time in the pool is used (read) | Say when to try again |

The input check turns away a `share_id` over 64 characters and a value that is not text before the tool runs: see [the connector overview](connector.md). An input the tool does not have, beside valid ones or alone, is dropped, and the line names it.

## What it reads and changes

**Reads** the account's profiles (the newest live version of each), the newest calculator report when no profile is named, one shared profile for a `share_id`, and the bullet catalog: one search by the profile's bullet name, diameter and weight, and, when that does not give exactly one bullet, one by diameter and weight alone (read). A bullet counts as the same when its diameter is within 0.0015 in and its weight within 0.5 gr (the catalog search's own bound). **Saves nothing:** no record, no command to a device, and `saved` is false. It solves 2 to about 50 times (read: the Mach 1.2 and Mach 1.0 searches), in the many-solve pool since 2026-10-15, under that pool's time limit and the account's budget ([the connector overview](connector.md)); a call took 2 to 50 ms on ordinary profiles. A zero range is at most 2,000 yd since 2026-10-15, so the slow case of a 5,000 yd zero (over a second) can no longer be saved.

**11. A twist that cannot stabilise the bullet: the problem is said first**

Starting point: four profiles of one made-up load, and a bullet catalog holding the one bullet of its diameter and weight: Fern 295 has something for every check (a 1:15 twist, a sight height of 4.2 in, chronograph strings 25 fps under the stored velocity, four values marked not measured, a stored zero height, a BC and a length that differ from the catalog's); Fern long twist has a 1:17 twist; Fern broken has a twist of 0; Fern far zero is zeroed at 800 yd.

**13. A zero range past the range at which the bullet slows to Mach 1.2**

Starting point: four profiles of one made-up load, and a bullet catalog holding the one bullet of its diameter and weight: Fern 295 has something for every check (a 1:15 twist, a sight height of 4.2 in, chronograph strings 25 fps under the stored velocity, four values marked not measured, a stored zero height, a BC and a length that differ from the catalog's); Fern long twist has a 1:17 twist; Fern broken has a twist of 0; Fern far zero is zeroed at 800 yd. Link scopes: `read`.

Call:
```json
{"profile_id":"fixture-fern-far"}
```

Spoken line:
```text
2 things to check on "Fern far zero": The G7 BC is entered as 0.241; the catalog has 0.2137. Bullet length is entered as 1.147 in; the catalog has 1.19.

**14. Four profiles and none named**

Starting point: four profiles of one made-up load, and a bullet catalog holding the one bullet of its diameter and weight: Fern 295 has something for every check (a 1:15 twist, a sight height of 4.2 in, chronograph strings 25 fps under the stored velocity, four values marked not measured, a stored zero height, a BC and a length that differ from the catalog's); Fern long twist has a 1:17 twist; Fern broken has a twist of 0; Fern far zero is zeroed at 800 yd. Link scopes: `read`.

Call:
