…integrity hook)

The memory-index-integrity check on AceHack #46 flagged the missing
paired MEMORY.md edit when the install-strategy memory file was
modified. Add a one-line note to the index entry recording the
2026-04-27 wording fix per Copilot LFG Lucent-Financial-Group#643 P1.

Hook satisfied; auto-merge will retry.

…current reference (#46)

* fix(substrate): reword nonexistent-doc xref — `docs/research/post-install-typescript-conventions.md` is a proposed location, not a current reference

Copilot P1 finding on the LFG sibling PR (Lucent-Financial-Group#643)
flagged that the install-script language-strategy memory file referenced
`docs/research/post-install-typescript-conventions.md` ambiguously
("capture the conventions in <path> or similar"). The path doesn't
exist; readers (Copilot included) parse this as if the doc were a real
artifact.

Reword to make it explicit that this is a proposed future location,
not a current reference. Same fix already landed on the LFG sibling
branch; this PR keeps the AceHack homebase-first invariant.

No behavioural change. Substrate-text only.

…nonexistent doc xref) (#645)

* ci: rename nightly-low-memory.yml → low-memory.yml (cadence is config, not identity) (#45)

* ci: rename nightly-low-memory.yml to low-memory.yml — cadence is config, not identity

Maintainer 2026-04-27: *"when it becomes per merge this won't be a
good filename anymore"*. With #44 the workflow now triggers on every
merge to main + nightly + workflow_dispatch — "nightly" in the
filename is misleading.

Rename rationale:
- `low-memory.yml` describes the *purpose* (low-memory drift
  detection on ubuntu-slim).
- The cadence (per-merge + nightly + manual) is a config detail
  that lives inside the file's `on:` block. Filename should not
  encode mutable cadence — it should encode timeless intent.
- Filename-history note retained inside the file's header comment
  so future maintainers can find the rename via grep.

Updated:
- `name:` field: `nightly-low-memory` → `low-memory`
- `concurrency.group:` `nightly-low-memory` → `low-memory`
- `gate.yml` cross-references at lines 12, 99, 125
- Header comment block reframed (purpose + filename history)

Branch protection: this workflow runs on push-to-main (not pull_request),
so it never appears as a PR-level required-status-check. No
branch-protection update needed.

LFG sibling: forward-sync via cherry-pick after this lands on AceHack.

* docs: clarify push-to-main vs merge-to-main per Copilot P2 (PR #45 thread)

Copilot P2 finding: comments said "every merge to main" but the
trigger is actually \`push: branches: [main]\` which is broader
than merges (also fires on direct pushes if branch protection
ever lifts).

Reword to "every push to main (in practice every merge — direct
pushes are blocked by branch protection)" so the technical
behavior and policy intent are both clear without misleading
future readers.

Two files touched (gate.yml header + low-memory.yml header).
The intra-policy phrasing inside Aaron's verbatim quote and the
"Why post-merge + nightly..." rationale stay as merge-language —
those describe policy/intent, not technical behavior.

* preserve(threads): per-commit concurrency from LFG #644 (Codex P2 + Copilot P1)

The cherry-pick from AceHack #45 used --strategy-option=theirs which
took the AceHack version of low-memory.yml — that version had the
older constant-group concurrency (\`group: low-memory\`,
cancel-in-progress: false), which silently replaces older pending
runs on burst pushes.

Restore the per-commit concurrency improvement that landed on LFG
#644 (\`group: low-memory-\${{ github.sha }}\`) so this forward-sync
doesn't regress the LFG state. Each push to main gets its own slot,
runs in parallel, no replacement.

Follow-up: open a small AceHack PR with the same concurrency fix to
keep the homebase-first invariant — next AceHack→LFG sync round
should be 0-diff on this file.
