StellarCrowandClaude Fable 5.1 439e83a4cb feat(sources): Wayback pass, automatic trimming, detention rule, ten cases re-sourced 
Second and third rounds on the dossier pipeline, reviewed locally before commit.

Retrieval
- wayback_pass.py: retries every BLOCKED/DEAD/THIN/ERROR linked source through
  the Wayback Machine; blocks carry the snapshot date, archive URL and the live
  verdict. 143 slots retried: 93 fetched, 37 no snapshot, 12 script shells, 1 PDF.
- fetch_sources.py: fetch_wayback() helper.
- add_extra_sources.py: files staged extra_* finds (web search, not on the DB
  record) into the store with a provenance note.
- Cases re-sourced by web search: 248 (Oslo: Document.no, Avisa Oslo, NRK; the
  linked Le Parisien piece is case 242 and is marked OFF-CASE), 258 Kharkiv,
  260 Singapore, 358 Bangkok, 365 Las Vegas, 388 Verneuil-sur-Seine, 390 Zoersel,
  430 Homestead. 341 of 364 cases now hold a fetched article; 11, 66 and 399
  have no public text source (podcast, police video, direct victim report).

Trimming
- auto_trim.py: case-anchored furniture cut for UNTRIMMED blocks. Finds the body
  run that mentions the case, merges across subheadings and short furniture
  gaps, drops teasers, share bars, date/URL/caption lines and subscription
  pitches; refuses pages with no record term or almost no body. 302 blocks
  trimmed; 16 left on auto-trim-review.md (7 OFF-CASE suspects). Every cut is
  labelled AUTO-TRIMMED, UNREVIEWED in the dossier; the full extract stays in
  staging/. Decisions with anchors in trim-decisions-auto.json.
- build_cases.py / verify_all.py: banners for auto-trimmed and archived blocks,
  staged-file check extended to Wayback blocks, flag legend under the record.

Detention rule
- README "Definitions": the DB field `kidnappings` is the DETENTION violence
  type (victim, guard, staff or relative held to force submission or execute
  the theft), distinct from the Kidnapping scenario (taken away and held).
- detention-flag-review.md / detention-flag-corrections.json: 40 records
  reviewed with evidence; 30 set-to-1 proposals accepted by the owner on
  2026-09-06 (listed in corrections-approved.md), 10 still open.
- apply_detention_wording.py: "Violence Used" in the 70 reviewed summaries now
  names detention explicitly (62 of 70 labelled), supported by the summary's
  own text; idempotent; supersedes the batch scripts' wording.

Worklist and docs
- sofia-worklist.md: 248 decisions, detention rule item replacing the old
  "no abduction" item, fresh-search section for the textless cases.
- README-START-HERE.md: progress notes, run commands, next steps.
- Bug fixed in passing: Wayback blocks stored in-memory text with carriage
  returns; now stored as read back from disk.

verify_all.py PASSES (2321 checks).

Singaporean out on bail allegedly kidnapped and tortured in Thailand
He was on a business trip while out on bail after being charged with cheating here last year
A Singaporean businessman facing cheating charges here was allegedly kidnapped and tortured in Thailand last week.
Despite paying his captors more than $60,000 in Bitcoin for his freedom, Mark Cheng Jin Quan, 32, claimed they were still going to execute him at gunpoint until he managed to escape.
The blockchain adviser with Singapore fintech company X Infinity said he reported the kidnapping to Thai police last Friday, hours after his escape.
He was worried about his Singaporean acquaintance, Kim Lee Yao Wei, 31, who had also been kidnapped after accompanying him on the business trip to Thailand.
But in a dramatic twist yesterday, the Royal Thai Police told a press conference that Lee was the alleged mastermind of the kidnapping and had been arrested and charged with robbery, illegal detention, physical assault and illegal possession of firearms.
FOUR CHARGES
Cheng was slapped with one charge under the Securities and Futures Act and three charges for criminal breach of trust in the State Courts here last year.
He is alleged to have dishonestly misappropriated more than $300,000 belonging to an investments company in 2014.
Cheng was given bail of $120,000 for permission to go to Thailand and Malaysia for work-related matters last Wednesday.
He reportedly arrived at Suvarnabhumi Airport in Bangkok with Lee, whom he knew through Bitcoin dealings, on Thursday morning.
Cheng claimed Lee had persuaded him to go to Thailand and negotiate a business deal with some locals.
They took a private taxi at the airport and later stopped at a petrol kiosk along the way at Lee's suggestion, Cheng told Chinese evening daily Lianhe Wanbao.
At the kiosk, a group of masked men allegedly grabbed and bundled them into a nearby car. They were then blindfolded, beaten and drugged.
Over the next 12 hours, he was taken to four different locations in forested areas where he was tortured, Cheng told Wanbao.
"They took off my clothes, splashed ice water on me and gave me electric shocks. They demanded that I hand over US$1 million (S$1.3m) in Bitcoin," he said.
But he told them he could give them only 1.4 million baht (S$62,400) in Bitcoin. After he paid them, they took him to a hut in a padi field where they pointed a gun at his head.
He had earlier heard men digging what he believed to be a grave, he told Wanbao.
"One of them held the gun against the back of my head while the others stepped away.
"Fortunately, I know martial arts. I reached behind my head and grabbed the pistol, and then I fled," he said.
Royal Thai Police spokesman Colonel Krisana Pattanacharoen said a good Samaritan picked up Cheng at the side of the road and took him to Ongkharak Police Station, some 60km from Bangkok, where he made a report at about 7.30am last Friday, Thai news outlet Siam Rath reported.
Colonel Krisana added that Lee was arrested on Sunday in a Bangkok hotel after a manhunt.
Mr Chano Pemberger, a 24-year-old Thai actor, who allegedly owns the car used in the kidnapping, is currently a person of interest in the case, Thai news outlet Sanook reported.
Cheng is still shocked by the revelation that Lee had allegedly masterminded the kidnapping, Wanbao reported.
"I didn't expect my friend to be involved. I really don't know who I can trust now," he said.
Cheng, who claims he is currently under police protection in a safe house in Thailand, is expected to testify in Lee's trial at a later date.
Cheng, who co-founded Avelife, a non-governmental organisation that focuses on social enterprise and the environment, is the first Singaporean to win the Queen's Young Leaders Award in 2016 for his involvement in environmental initiatives.
It is not known if he will return to Singapore for his next court hearing on Feb 3.
