docs(user): user-facing documentation (index, getting-started, concepts, capabilities, api-reference, extending, migration) - #33
Conversation
…ncepts, capabilities, api-reference, extending, migration) Implements the first two rounds of user docs under docs/user/ for Python novices, pros, and notebook researchers: - index + getting-started (pip/uv/notebook, register -> contract -> canonicalize) - concepts hub + 7 deep dives (capabilities, contracts, pipeline with staged recognition explanation, execution-result, provenance, candidates & ambiguity, errors) with Mermaid diagrams per page - capabilities hub + 10 per-capability guides (email, date, country, currency, ip, isbn, money, phone, si-unit, url) — each with recognized forms, canonical output & output_format, contract flags, status examples, notebook snippet, and provenance - api-reference (registration, canonicalize(), contracts, ExecutionResult, Provenance, Resolution, errors) + extending (community grammars/rules via extra_grammars) + migration (SemVer & upgrade checklist) Constraints: no links to docs/development or docs/adr, no fixed capability count — all lists framed as the current growing release.

Inline comments:
In `@docs/user/capabilities/country.md`:
- Around line 111-115: Update the exception handling around paxman.canonicalize
in the notebook example to catch only the expected Paxman exception types,
include the caught exception message by printing e, and allow unexpected
exceptions such as contract, registration, grammar, or rule failures to
propagate.
Apply the same fix in `@docs/user/capabilities/money.md` at line 63.
In `@docs/user/capabilities/currency.md`:
- Around line 11-16: The currency recognition table must align with the
documented status model: describe wrong-length or unsupported-casing inputs as
unmatched by the grammar and therefore yielding MISSING, not INVALID. Update the
affected “Does not recognize” entry while preserving INVALID for values that
match a currency pattern but fail validation.
In `@docs/user/capabilities/date.md`:
- Around line 78-85: Remove the EN 50160 date attribution from the rules
diagram, replacing it with the shipped rule identifier Section 4-date-format if
the diagram is intended to list rule identifiers; otherwise remove the European
entry. Update the related provenance text near the date-format documentation to
match this correction.
In `@docs/user/capabilities/isbn.md`:
- Around line 69-76: Update the Mermaid flowchart’s Rules node to show that
Range Message validation is conditional on include_range_validation, while
keeping ISO 2108 and ISBN Users’ Manual checks unconditional and preserving the
existing success, invalid, and missing outcomes.
- Line 13: Update the ISBN-13 capability description to state that ISBN-13
bare-digit input must use a 978 or 979 prefix; keep ISBN-10 documented
separately as the form controlled by include_isbn10.
In `@docs/user/capabilities/money.md`:
- Line 38: The Python example contains an invalid bare expression,
Money.create_contract().canonicalized_value, that prevents it from running;
remove this line or convert it into a Python comment while preserving the valid
paxman.canonicalize() examples.
In `@docs/user/concepts/candidates-and-ambiguity.md`:
- Around line 112-115: Annotate the fenced output block containing the dated
authority examples with the text language identifier. Clarify the ISBN-13
description to state that every ISBN-13 uses a 978 or 979 prefix, and revise the
range-validation guidance so it distinguishes hyphenation from the
include_range_validation option. Remove or correct the Money example using
canonicalized_value on the contract instead of its execution result, and make
the shared-symbol example consistent with Currency by using USD or showing MYR
as INVALID.
In `@docs/user/concepts/errors.md`:
- Line 3: Update the errors overview, diagram, and summary to distinguish setup
or caller-misuse errors from pipeline failures such as RecognitionError and
ValidationError, and from unsegmented multi-mention input represented by
MultipleMentionsError. Treat a frozen registry as valid for ordinary
canonicalize() calls, with errors only for registration attempts after freezing,
and remove wording that implies Paxman could not inspect input before
MultipleMentionsError.
In `@docs/user/concepts/execution-result.md`:
- Around line 95-96: Update the execution-result documentation to avoid stating
that every agreeing candidate’s span matches result.span. Describe result.span
as the resolved span selected from the result, and direct users to inspect each
candidate.span when they need all evidence locations.
In `@docs/user/concepts/index.md`:
- Line 3: Update the introductory text in the concepts index so its stated
concept count matches the seven entries in the table, and remove or revise the
separate wording that presents Errors as an additional seventh page. Keep the
page’s concept list and navigation unchanged.
In `@docs/user/concepts/provenance.md`:
- Around line 17-20: Update the provenance example’s print expression to output
c.validation_rule instead of checking for the nonexistent Candidate citation
attribute, while preserving the existing authority, specification name, and
version fields.
In `@docs/user/extending.md`:
- Around line 135-138: Update the Date.create_contract examples to pass each
returned contract through paxman.canonicalize() before accessing
canonicalized_value, preserving the dormant default and opted-in dot-date
behavior.
In `@docs/user/migration.md`:
- Around line 79-80: Update the “Review contracts” checklist item to validate
only rule names in pinned_rules and excluded_rules, while separately confirming
that CountryContract.year remains an intentional supported temporal filter; do
not describe year as a rule name.
- Around line 20-24: Update the version-bump policy table and related sections
to separate contract compatibility from result stability: PATCH and MINOR
releases must not promise unchanged recognition, status, or canonicalized_value
when spec data or authority tables change. Require golden-sample reruns for data
changes, advise pinning the package version and contract.year, and storing
version_stamp. Correct the year documentation to state that it filters rules by
publication_year <= year, while only pinned_rules and excluded_rules identify
rules; align the surrounding release-policy guidance without treating provenance
or specification changes as inherently MAJOR.

EN 50160 scope electricity voltage characteristics date calendar standard IEC
💡 Result:
The standard EN 50160, titled Voltage characteristics of electricity supplied by public electricity networks, specifies the main characteristics of voltage at the supply terminals of network users in public low, medium, high, and extra-high voltage alternating current (AC) electricity networks [1][2][3]. Key aspects of the standard include: Scope and Application The standard is applicable only to public electricity networks in Europe [1][4]. It explicitly excludes industrial networks [1][2]. It applies exclusively under normal operating conditions and does not cover abnormal situations such as temporary supply arrangements during faults or maintenance, cases of non-compliance of user installations, or exceptional events like natural disasters, force majeure, or industrial actions [1][5][4]. Relationship to Other Standards EN 50160 is a product standard that defines the minimum performance requirements that the voltage must meet at the grid operator's transfer point [6]. It is distinct from electromagnetic compatibility (EMC) standards; the voltage characteristics it provides are not intended to be used as EMC levels or product emission limits [5][7]. Regarding measurement, the standard refers to EN 61000-4-30, which defines the measurement methods and the performance of measuring instruments (e.g., how they should measure and calculate parameters like frequency, magnitude, and waveform) [7][6]. While EN 50160 acts as a regulatory or contractual "highway code" for supply quality, EN 61000-4-30 provides the technical specification for the "speedometer" used to verify compliance [6]. Current Status As of August 2026, the standard remains active and subject to updates [8][9][3]. It has undergone various revisions, and regional implementations—such as BS EN 50160 (UK), NEN-EN 50160 (Netherlands), or CEI EN 50160 (Italy)—frequently incorporate amendments (e.g., A1:2025) to maintain alignment with the base CENELEC standard [7][10][3]. Users should consult their local national standards body for the most current, specifically adopted version [11].
