iter docs-honesty-lint.1: canonical docs present-tense-honest + wrap-robust pin + Sweep 5

Strips Wunschdenken (forward intent stated as fact) and non-citation
post-mortem / doc-archaeology from docs/DESIGN.md (14 corrections incl.
1 Step-14 procedural-catch-all site the spec's illustrative regex would
have missed) + docs/PROSE_ROUNDTRIP.md; genuine forward intent (LLM
tool-use / MCP / LSP) relocated to roadmap P3. Codifies the
tense+modality discriminator as a present-tense DESIGN.md meta-
subsection. Guards two ways: wrap-robust enumerated absent/present pin
(crates/ailang-core/tests/docs_honesty_pin.rs, norm() whitespace-
collapse helper — structurally discharges the recurring grep/contains
line-wrap failure family) + wrap-robust advisory Sweep 5 in
architect_sweeps.sh (contiguous-fragment regex) with full sweep-count
lockstep + new ailang-architect.md "DESIGN.md honesty drift" bullet.
KEEPs preserved (Diverge-reserved, regions-rejected, self-labelled
tiebreaker). No language/checker/codegen/runtime change — sole crates/
change is the additive pin; ail check/run/build byte-unchanged.
Workspace 609/0 (delta +4 pin), sentinel trio green, build clean.

+is not whether a sentence mentions past or future, but whether the

+
+**Date:** 2026-05-18
+**Started from:** de66eb7ab2e457bfe7e5dbe2f87c5da15a786cd7
+**Status:** DONE
+**Tasks completed:** 6 of 6
+
+## Summary
+
+`docs/DESIGN.md` and `docs/PROSE_ROUNDTRIP.md` carried Wunschdenken
+(forward intent stated as fact) and non-citation post-mortem /
+doc-archaeology narrative. This iter strips both classes, codifies
+the honesty discriminator as a `### What this document is — and the
+honesty rule it holds itself to` meta-subsection inside DESIGN.md
+§"Project ecosystem", and guards the invariant two ways: a
+wrap-robust enumerated absent/present regression pin
+(`crates/ailang-core/tests/docs_honesty_pin.rs`, 4 tests) and a
+wrap-robust advisory Sweep 5 in `bench/architect_sweeps.sh` with all
+sweep-count lockstep wording + a new `ailang-architect.md` "DESIGN.md
+honesty drift" bullet. Genuine forward intent (LLM tool-use / MCP /
+LSP) relocated to `docs/roadmap.md` P3. No language/checker/codegen/
+runtime change — the sole `crates/` change is the additive pin file;
+`ail check`/`run`/`build` are byte-unchanged by construction.
+
+## Per-task notes
+
+- iter docs-honesty-lint.1.1: created the wrap-robust RED pin
+  (`docs_honesty_pin.rs`, `norm()` whitespace-collapse helper, 4
+  tests). Verified RED for the right reasons (compiles, 4 fail on the
+  enumerated still-present strings + the absent discriminator).
+- iter docs-honesty-lint.1.2: appended Sweep 5 to
+  `architect_sweeps.sh` + tail "All four"→"All five" + header
+  "four"→"five sweeps"; added the "DESIGN.md honesty drift" architect
+  bullet and fixed the sibling "four sweeps"→"five / Sweeps 1-4"
+  wording. Sweep 5 confirmed firing on the uncorrected tree
+  (EXIT=1). Concern-1 lockstep shipped whole, no split.
+- iter docs-honesty-lint.1.3: inserted the discriminator
+  meta-subsection. Tree had drifted (a `- **Tests**:` bullet now
+  follows the Docs bullet, no blank line; closing prose is "When the
+  language grows…"); anchored on the verbatim closing-prose line per
+  the plan's own Step-1 "quote it, do not assume" caveat.
+- iter docs-honesty-lint.1.4: applied the 13 byte-exact corrections
+  (each verbatim "current text" re-confirmed by grep first; lines had
+  drifted +~22 from Task 3). Step-14 catch-all surfaced one genuine
+  extra FIX site (see Concerns); classified + handled per procedure.
+- iter docs-honesty-lint.1.5: stripped the PROSE_ROUNDTRIP tool-use/
+  MCP Wunschdenken paragraph (present-tense replacement); appended
+  the relocated forward-intent idea to roadmap P3 with spec
+  provenance. Full pin GREEN (4/4).
+- iter docs-honesty-lint.1.6: full verification — pin GREEN isolated;
+  workspace zero failures (609 passed, delta = +4 pin tests only);
+  sentinel trio (design_schema_drift/spec_drift/schema_coverage)
+  green; Sweep 5 reduced to the single self-referential L62 KEEP;
+  build clean; `ONLY THE PIN` scope confirmation.
+
+## Concerns
+
+- T3: plan Task-1 pin string `whether the document asserts something
+  exists, works, or changed that does not` omitted the `**…**`
+  Markdown bold that plan Task-3 body wrapped around `asserts …
+  not`. Plan self-review item 3 cross-check missed it. Resolved by
+  dropping the incidental bold from the inserted body (the pin is the
+  contract, written first; the emphasis is non-load-bearing). Prose
+  meaning + present-tense framing unchanged. Plan-internal
+  inconsistency, not a tree-drift; flagged for planner calibration.
+- T4: Step-14 catch-all surfaced one genuine extra Sweep-5 FIX site
+  not in Steps 1-13 — DESIGN.md Form-B class/instance prose-projection
+  bullet ("was deferred from milestone 22 entirely; … A future iter
+  ships the full prose projection if/when …"). The Boss's "zero extra
+  hits" pre-verification was against the spec's illustrative regex;

+- KEEP: DESIGN.md L62 `- **Forward intent** ("planned / will back /
+  on the path to / if-when X arrives")` — the discriminator
+  subsection's own enumerated catalogue of forbidden phrasings;
+  asserts nothing false, present-tense rule definition. A
+  self-referential Sweep-5 false-positive (the regex matches the
+  literal "on the path to" inside the rule's own example list).
+- FIX: DESIGN.md L2093 Form-B prose-projection bullet — see Concerns;
+  before→after recorded there; pin pair added.
+
+## Known debt

+- (none) — the iter is self-contained; the pin + Sweep 5 are the
