fix(post-#1662): replace wildcard amara path + grammar typo (4 threads)

[AceHack]

Summary

3 P0 + 1 P2 threads on already-merged #1662 (ombuds memory):

• 3x P0 (Copilot, existence-drift): Backticked docs/amara-full-conversation/2025-09-w*-aaron-amara-conversation.md wildcard doesn't match real files (actual: w1-w5). The substrate-claim-checker treats backticked .md as existence claims. Replaced with concrete 2025-09-w1-aaron-amara-conversation.md (and w2-w5) — backtick closes before the "(and w2-w5)" suffix so existence-check sees a valid path.
• 1x P2 (Copilot, grammar): "absorbed at staged" → "absorbed at distinct stages" (matches the linked soulfile memory wording)

Test plan

• All backticked .md paths in the file resolve to actual files
• Grammar typo corrected to match linked memory's wording

Pull request overview

This PR is a follow-up correction to the previously merged Ombuds memory entry: it replaces a wildcarded Amara conversation reference with a concrete path shape that satisfies the substrate existence checker, and it fixes one wording typo in a linked soulfile reference. In the codebase, this is documentation/memory hygiene work on a history surface under memory/.

Changes:

• Replaced three wildcard-style backticked docs/amara-full-conversation/...w*-...md references with a concrete w1 path plus “(and w2-w5)” prose.
• Corrected the soulfile summary text from “absorbed at staged” to “absorbed at distinct stages”.
• Kept the rest of the memory entry’s provenance/composition structure intact.
