2026-07-28: itd-104 spec minted as spc-16 (third live iss-80 instance this run: 16 collided with #156, 17 with the itd-101 branch); renumbered to spc-18 by hand.

• iss-80Record id allocators (itd-N, spc-N, iss-N) are branch-local: parallel agents on separate branches each scan for max+1 and mint the SAME id. Two intents both claimed itd-82 and both merged to main (PRs #46, #47). The iss-N allocator hit the same class before (iss-77 collision, manually renumbered to iss-79; class recorded as iss-74). Resolving a collision forces a renumber, which breaks the record's stated 'ids are capture-stable, never renumbered' invariant -- so the minting scheme, not the renumber, is the defect. This capture is the MINTING half: a collision-free allocation scheme is needed (forge-minted / random-suffix / timestamp / reserve-registry -- SOTA under research). The DETECTION half is armed separately: intent_lifecycle now blocks duplicate intent ids.
• itd-101**Every citation abcd publishes is provably alive and honestly labelled — and the gate that enforces it never flakes.** A cited reference page is only as trustworthy as its links, and links rot silently: pages retitle, URLs redirect, whole platforms announce their own shutdown. abcd splits citation validation across a deterministic gate and an explicit refresh. An offline lint family checks structure and source policy on every commit — footnote markers and definitions in bijection, URLs and DOIs well-formed, aggregator domains refused — with zero network in the gate. `abcd docs cite refresh` does the live fetching on demand and writes a committed baseline: per URL, the final resolved address, when it was last checked, and whether verification was automatic or manual — never how. Sources that block automated fetchers join a manual queue the maintainer clears link by link: printed as a checklist first, later as a generated, disposable checklist page that hands back a receipt file the verb ingests. The lint then enforces the baseline offline — no broken entries, no stale entries, no cited URL without a receipt, no citation whose recorded final address has drifted. The engine is native and dependency-free first; a specialist link checker can slot in later behind the same seam. "My release gate stays deterministic and my citations stay alive," said Kira, an open-source maintainer. "When a source needs human eyes, abcd hands me the exact list to click through and records that I did — not how I did it."
• itd-104**abcd gates a new idea before it becomes a record entry: research it against primary sources, grill it against the existing record, and let an independent adversary try to kill it.** A product thinker's exciting idea is cheapest to kill in its first hour — and most expensive to kill after it has minted intents, specs, and branches. `/abcd:ideate` runs the admission interview: SOTA research in which every load-bearing claim is checked against its primary source; a record grill — does the brief, an intent, an ADR, or a principle already cover, contradict, or supersede this?; and an independent adversarial review, evaluator outside the loop. The output is a verdict plus a recorded decision with rejected alternatives; only a surviving idea graduates to a draft intent. The protocol is already proven by hand: three ideas entered it on 2026-07-14 — two were killed (one by a measured null result its premise could not survive, one by three independently fatal methodological defects) and one was reframed by adversarial review before a line was built. The manual run also named the two load-bearing steps automation must keep: check the record first (one idea was already written and superseded), and open the primary (three secondary-source claims were falsified, one of them fabricated by tool extraction). "The ideas I'm proudest of are the ones abcd killed in an afternoon," said Iris, a product thinker. "Each one left a recorded reason behind, so I never talk myself back into them six months later."
