Umbrella: standard library roadmap (50 items, 5 tiers)

[hyperpolymath]

Umbrella tracker for docs/stdlib-roadmap.adoc (landed in #410).

50 stdlib items across 5 tiers — the .affine files in stdlib/, sequenced runtime gaps → RSR rewires → universals → concurrency → conformance.

Tier summary

Tier	Theme	Count
1	Idaptik runtime gaps (List len/++, dict, cross-file use, Option reach, etc.)	10
2	Estate convergence (Crypto/Http/Json/GitHub RSR rewires, Result/Option helpers, traits, math, io)	10
3	Universals (Time, UUID, Regex, URL, Base64/hex, Logging, Date, Number fmt, Float utils, Bytes)	10
4	Concurrency/async/effects (async, Task, Channel, Mutex, Atomic, Cancel, Timer, Select, Stream, Actor)	10
5	Conformance/introspection (aLib, effects calc, capabilities, borrow helpers, diagnostics, reflect, serde, testing, bench, doc-comments)	10

Sequencing (from the doc)

• Phase A (unblock idaptik PR Cross-module imports: TopConst not threaded by gen_imports / flatten_imports #107 successor): ci: Bump actions/github-script from 7.0.1 to 8.0.0 #5 (cross-file use) → ci: Bump trufflesecurity/trufflehog from 3.92.5 to 3.94.1 #6 (Option reach) → ci: Bump actions/setup-node from 4.0.2 to 6.3.0 #1 (List.len runtime) → ci: Bump dtolnay/rust-toolchain from f7ccc83f9ed1e5b9c81d8a67d7ad1a747e22a561 to efa25f7f19611383d5b0ccf2d1c8914531636bf9 #2 (List.++ runtime) → ci: Bump github/codeql-action from 4.31.10 to 4.35.1 #7 (Dict runtime)
• Phase B (RSR convergence): bindings refactor(manhattan-recovery): scope recovery + complete grammar refactor + rip dependent-type creep #19 (Zig FFI doc) → ci: Bump trufflesecurity/trufflehog from 3.94.1 to 3.94.2 #11 (Crypto) → ci: Bump webfactory/ssh-agent from 0.9.1 to 0.10.0 #12 (Http) → ci: Bump actions/configure-pages from 5.0.0 to 6.0.0 #13 (Json) → ci: Bump actions/deploy-pages from 4.0.5 to 5.0.0 #14 (GitHub)
• Phase C (helper coverage): Rename AffineScript file extension from .as to .affine #15 (Result helpers) → feat: migrate file extension from .as to .affine for GitHub Linguist … #16 (Option helpers) → refactor(manhattan-recovery): scope recovery + complete grammar refactor + rip dependent-type creep #19 (Math expanded) → ci: bump trufflesecurity/trufflehog from 3.94.2 to 3.94.3 #20 (Io expanded)
• Phase D (universals): ci: bump actions/upload-pages-artifact from 4.0.0 to 5.0.0 #21 (Time) → ci: bump editorconfig-checker/action-editorconfig-checker from 2.1.0 to 2.2.0 #23 (Regex) → ci: bump ocaml/setup-ocaml from 3.4.8 to 3.6.0 #24 (URL) → feat: migrate file extension from .as to .affine for GitHub Linguist … #25 (Encoding) → a2ml: rename runbook out of .launcher.a2ml namespace #26 (Logging)
• Phase E (demand-driven): Tier 4 + 5 as consumers ask.

Child issues

Tier-1 starting point:

• Cross-file use resolvability from standalone check (stdlib ci: Bump actions/github-script from 7.0.1 to 8.0.0 #5) — name-resolver / prelude organisation

Item numbers in docs/stdlib-roadmap.adoc are stable; reference as stdlib #N.

Notes

• Tier 1 items ci: Bump actions/setup-node from 4.0.2 to 6.3.0 #1-4, ci: Bump github/codeql-action from 4.31.10 to 4.35.1 #7-10 are mostly runtime / codegen work, not new .affine surface — they exist at the type-checker level but fail at eval / wasm-codegen.
• Tier 4 is heavily tracked-by-main-ROADMAP (language-level async, effects, capabilities); the stdlib surface is the visible API.

[hyperpolymath]

Tier-1 child issues opened:

• stdlib #5: cross-file use resolvability from standalone check #415 — stdlib ci: Bump actions/github-script from 7.0.1 to 8.0.0 #5: cross-file use resolvability from standalone check (covers ci: Bump actions/github-script from 7.0.1 to 8.0.0 #5/ci: Bump trufflesecurity/trufflehog from 3.92.5 to 3.94.1 #6/ci: Bump erlef/setup-beam from 1.17.5 to 1.24.0 #10 family)

Other Tier-1 items (List.len/++ runtime, dict runtime, for-in codegen #255, String.length/concat runtime) remain in docs/stdlib-roadmap.adoc; open child issues for them when work starts.
