Survey now covers 10 prior-art clusters (was 8). New clusters per
user direction (Option A in the v1.2 cluster-fit discussion):
NEW: research/cluster_8_metadesk.md (research sub-report):
- Metadesk (Ryan Fleury + Allen Webster, Dion Systems, 2020-2021)
- 5 distinctive design properties: uniform 'lego-brick' AST, tags
as dispatch keys, multiple interchangeable delimiters, comment
+ source-location preservation, first-class C interop with
copy-paste distribution
- 2 citable anchor quotes with source URLs
- Synthesis: maps to Tier 3 (read/edit/discover) and Tier 4
(audit/fuzzy) verbs
NEW: research/cluster_9_verse.md (research sub-report):
- Verse (Simon Peyton Jones + Tim Sweeney, Epic Games, 2021-)
- 5 distinctive design properties: transactional semantics with
speculative execution, failure as first-class control flow, effect
tracking in function signature, new Verse Calculus (ICFP 2023
Distinguished Paper), everything-is-an-expression + live variables
- 3 citable anchor quotes
- Synthesis: maps to Tier 4 (try/recover/sandbox/audit) verbs;
two-layer failure model maps to Cluster 7's Result convention
UPDATED: report_v1.2.md (1343 lines, +42 from v1.2 base):
- Inserted Cluster 8 (Metadesk) and Cluster 9 (Verse) sections
between Cluster 7 and the section 2/3 divider
- Updated §2 intro to say '10 clusters' (was '8')
- Updated glossary 'clusters' entry to list all 10
- Updated v1.2 changelog note (4) to document the cluster additions
UPDATED: tracks.md:
- Track #23 status line now lists all 10 clusters
- Goal line updated to say '10 clusters' (was '8')
UPDATED: state.toml deliverable_summary:
- Added v1.2_changes[4] for the cluster additions
- Added cluster_count = 10
- research_sub_reports now lists 7 cluster files (0-9)
The spec/plan/review files still say '8 clusters' — left as
historical context (spec is approved with 8; expanding to 10 is
an editorial decision the user has now made; future revisions of
spec/plan should reflect 10).
