A hand-written summary of a statute is correct on the day it is written and decays silently after that. Nothing in the archive would show it: the answer still reads well, still cites a real source, and is simply out of date. That is the worst failure this project can have, because it looks exactly like success. This compares the current text of each source against a recorded fingerprint and names the answers that depend on anything that moved. The fingerprint is taken over the *cleaned* text, not the HTML. Government pages regenerate constantly with unchanged content: banners, session ids, build timestamps. Hashing the raw response would cry wolf every week, and a monitor that cries wolf is one people learn to ignore. ) annotationsN)datetimetimezone)Path) PLAIN_SOURCEScleanfetchsplit_sectionszdata/freshness.jsontextstrreturncCs&td|dddS)z0Hash of the cleaned text, whitespace normalised. utf-8N)hashlibsha256joinsplitencode hexdigest)r r2/root/openrights-assistant/openrights/freshness.py fingerprints&rrootrdict[str, list[str]]cCsv|d}i}|s |St|dD]%}t|jd\}}}|s"qddt|jddD}||g |q|S)zFWhich answers rest on which statute, so a change names its casualties.z data/curatedz*.md)rrcSsg|]\}}}|qSrr).0h_rrr ,sz&answers_by_statute..rencoding) existssortedglobrgetstemr read_text setdefaultextend)r directorymappingpathrstatuteheadingsrrranswers_by_statute"sr0titlecCs4tD]\}\}}}||vr|SqdS)z=Match a source title to the statute name used by the answers.r)ritemslower)r1rr.rrrstatute_for_source1s r4Fupdatebooldictc Cst|djdd}|t}i}|r"t|jdddi}t|}tt j j dd }i}g}g} |D]} | d} zt | d|d | d } Wn-ty}} z!| | | |vrsi|| d t| dd i|| <WYd} ~ q:d} ~ wwtt| }|| i}| d |||d|d}|dr|d|krt| d }|| | d |d||dd||gd|d||d<n|r||d<||| <q:|s|s|jjddd|jtj||ddddddt||| | dS)Nzdata/sources.jsonrr!sourcesr) microsecondidurlzdata/rawz.htmlerrorxr1verified)r1rcheckedr>runknown)r:r1wasnowr>answersT)parentsexist_ok)updatedr8)indent )r?changed unreachable first_run)jsonloadsr(MANIFESTr#r&r0rrBrutcreplace isoformatr Exceptionappendr rrr4parentmkdir write_textdumpslen)rr5r8 manifest_pathprevious dependantsrBcurrentrJrKsource source_idrawr<digestbeforerecordr.rrrcheck9sj  $         rdresultintcCs|drtd|dddS|dD] }td|dq|d s4t|dd |dr2d SdStt|d d |dd |d D]:}td|dtd|d|dr{tdt|dd|dD] }td|qpntdtqHtdtddS)zEPrint the result.
