• 5 September 2026Track-B documentation wave: services category — mandatory Test-1 self-contradiction fix (service-fs-data-lake), Test-3 split, structural + mechanical frontmatter fixes across 17 articles89c36c1a
• 22 August 2026editorial(services): rewrite service-fs (Track-B) — confirmed real HTTP routes (append/checkpoint/entries/contract/healthz/readyz) plus a real MCP endpoint, resolving the article's own narrated 2026-08-02 correction by stating the fact directly instead; confirmed real 4-layer architecture and ledger trait (append/read_since/checkpoint/verify_inclusion/verify_consistency) directly against ledger.rs's own doc comments; confirmed real audit-log sub-ledger and C2SP signed-note/tlog-tiles formats; major correction: no main_sel4_stub.rs exists and no vendor-sel4-fs directory exists in this checkout — Cargo.toml's own comment says the seL4 unikernel scaffold was relocated out of this crate (package version reset 1.0.1->0.1.0, 'a fresh hosted MCP-server skeleton with a different runtime model'), contradicting the article's 'Envelope B (seL4) exists as a reference entry point' claim; dropped the fabricated service-pointsav-link link and unverified SEC/eIDAS/SOC2 compliance-claim specifics; register-clean EN+ES3c2a73d8
• 6 August 2026fix(index-group): backfill index_group across 11 categories migrated to Index Topic (330 files)9b9339a2
• 2 August 2026fix(services): add dated Correction callouts to 10 of 13 services/ batch-1 articles — worst defect ratio of any category (fabricated proofreader/message-courier/chart-of-accounts mechanics, reversed egress data-flow direction, wrong Graph vs real EWS integration, wrong extraction routing model, understated service-fs capability; private-git-paid-customer-endpoint.md finding disproven, agent checked wrong crate, no correction applied; service-input.md and service-fs-data-lake.md already correctly self-corrected20f78a6a
• 2 August 2026content(services): consolidate service-fs-architecture.md + service-fs-security-compliance.md into one canonical services/service-fs.md — confirmed genuine redundancy (same subject: WORM ledger, Merkle chains, Rekor anchoring, seL4 target, described twice from architecture vs. compliance angles). Archived both old files (.archive/, EN+ES) with mandatory frontmatter; aliases: field + redirects.yaml entries preserve all ~44 existing inbound wikilinks/URLs without hand-editing every referencing file. Updated services/_index.md MOC. service-fs-data-lake.md investigated separately and kept apart — genuinely different subject (GIS landing-zone directory convention, not the WORM ledger service).cc373e03
