+# Link acquisition ledger (#14)
+
+Honest link acquisition only: submissions where keel genuinely fits, always
+with maintainer disclosure, never astroturfed (issue #14's own rule). Every
+external action is recorded here with its status.
+
+## Submissions
+
+| Date | Target | Action | Status |
+|---|---|---|---|
+| 2026-08-22 | awesome-islamic-finance (goww7) | PR goww7/awesome-islamic-finance#2 — Developer Tools & APIs | Open, awaiting owner |
+| 2026-08-22 | awesome-crypto-trading-bots (botcrypto-io, 2.5k★) | PR botcrypto-io/awesome-crypto-trading-bots#136 — Open source bots | Open, awaiting owner |
+| 2026-08-22 | awesome-selfhosted (314k★) | PR awesome-selfhosted/awesome-selfhosted-data#2957 — `software/keel.yml`, Money, Budgeting & Management | Open, awaiting review |
+| 2026-08-22 | awesome-islamic-open-source-apps (tarekeldeeb) | PR tarekeldeeb/awesome-islamic-open-source-apps#7 — Other/Python, TOC count bumped | Open, awaiting owner |
+| 2026-08-22 | engine repo topics | Added `cryptocurrency` to existing islamic-finance/shariah-compliant/halal set | Done |
+
+**Note discovered the hard way:** awesome-selfhosted's readme repo rejects
+PRs by design ("Please do not submit pull requests in this repository") —
+submissions go through `awesome-selfhosted/awesome-selfhosted-data` as a
+`software/<name>.yml` file. OctoBot's entry was used as the schema template.
+
+## Community participation (maintainer's hands, not the site's)
+
+Drafts below are ready to post **from the maintainer's own Reddit account**,
+disclosure first. Do not post from anywhere else; do not use vote rings.
+
+### r/IslamicFinance — text post draft
+
+> **I built an open-source tool that enforces (not decides) Shariah compliance on spot crypto — sharing because this community's scrutiny is exactly what it needs**
+>
+> Full disclosure up front: I'm the maintainer, this is my project, and I'm not here to sell anything — it's Apache-2.0, self-hosted, and there is no paid tier.
+>
+> keel is a compliance engine, not a fatwa machine. It never decides what's halal — you record classifications (with sources), and it enforces them deterministically: assets without an attestation are refused, trades only spend settled balances, AAOIFI §65.4 qabd is an actual executable check, and interest that accrues inside the account is counted so the purification amount is reported, not guessed.
+>
+> The honest result, stated by us first: none of our shipped trading rules is net-positive at the fees actually paid. We publish that on the front page. The project is the enforcement machinery and honest measurement, not alpha.
+>
+> Site with plain-language docs (EN/AR/FR): keeltrading.com — code: github.com/CodeGateSoftware/keel
+>
+> What I'd genuinely value from this community: does the fiqh framing convince you? What's missing? There's a Compliance & classification category in Discussions where classification questions are welcome as questions.
+
+Engagement rules for follow-ups: answer questions in the comments as the
+author, link the fiqh-basis doc when challenged on specifics, never claim
+scholarly endorsement (none has occurred — say so plainly).
