This is the full batch of the #980 campaign. tools/probe/campaign.sh recorded it on 2026-09-28 at the 30 repetitions per probe that the tier declares. The owner scheduled it on #980. It covers sufficiency and navigability. Discovery is left out, because the second pilot found that discovery measures the instrument (option (a) on #980).

One batch, one tree. Every session ran in a fresh copy of one git archive of commit d0daebc4, with the engine that commit builds, in one order that seed 980 shuffled, four at a time, on claude-sonnet-5 with a cap of 60 turns. Each workspace lost the instrument, every record under docs/ that names a probe of the batch, and the answer keys of those probes. Each absent workspace also lost its tier's ablation.

The oracle. A patched artifact of either arm was checked in a copy of the present tree with the artifact written into it (probe-transform.sh --oracle-tree), so one oracle graded both arms.

This transcript stands at deprecated, and the reason is the read set of its probes. The lock above is not the lock of this tree, and the engine reads such a recording only while the read set of its probes is the one this tree composes. On 2026-09-29, #1294 revised the summary of HW-DR-0052, so that a route over the task of the status probe offers that ruling. The register of decisions and the register of open questions print that summary, and the probes of this selection examine both registers. So the read set of this selection moved, and the first of the five confirmations now refuses this recording. The owner ruled on 2026-09-29 to retire the five full-batch transcripts rather than record them again. The result derived from this transcript carries no verdict on a later tree, and its verdicts stand only in the history of that result. A reader may take no rate from it as a measurement of the corpus as it now stands.

I need to find the specific mechanism this refers to, AND the specific ruling/decision document it rests on (there should be a decision doc, likely under docs/decisions/ or docs/process/decisions/, or docs/spec/09-decisions.md, that explains WHY this design choice was made — computed vs. stored).\\n\\nCandidates to investigate:\\n1. The identifier claim store at .headwater/ids/<scheme>/<identifier> — CLAUDE.md mentions \\\"Before minting, scan every remote branch for the highest identifier in use, not only main\\\" and cites docs/decisions/0054-the-upper-bound-of-a-reconcile-first-allocator-is-the-corpus-and-a-claim-store.md — this sounds very promising: the \\\"highest identifier\\\" is a count/scan over the corpus computed live rather than stored in a committed file (like a counter file).\\n2. Search docs/decisions/ and docs/process/decisions/ for anything about counts, counters, caching, computed-at-read-time vs stored, derived values, or \\\"the corpus\\\" as source of truth.\\n3. Search docs/spec/ (especially 09-decisions.md) and docs/requirements/, docs/obligations/ for related material.\\n4. grep the engine/ source (Rust) for anything computing counts over \\\"corpus\\\" - e.g. searching for word \\\"corpus\\\" combined with \\\"count\\\" in engine/ or docs/.\\n5. Check docs/decisions/0054-*.md in full — read it completely.\\n6. Also check if there's anything about a \\\"highest identifier\\\" counter, sequence numbers, or similar allocator patterns explicitly rejecting a committed counter file in favor of scanning.\\n\\nPlease:\\n- Read docs/decisions/0054-the-upper-bound-of-a-reconcile-first-allocator-is-the-corpus-and-a-claim-store.md in full and report its exact content (or the relevant excerpt) including its decision ID, title, and the reasoning.\\n- grep for other decision docs that mention \\\"counter\\\", \\\"committed file\\\", \\\"worked out when read\\\", \\\"computed at\\\", \\\"cache\\\", \\\"scan the corpus\\\", \\\"highest identifier\\\", \\\"reconcile-first\\\".\\n- Report the exact file path(s), decision numbers, and quote the key sentences that justify computing something over the whole corpus at read-time rather than storing it in a committed file.\\n- Also note any OTHER candidate mechanisms in the repo (not just the identifier allocator) that fit this \\\"count over corpus, computed at read time not stored\\\" pattern, in case the identifier allocator isn't the right one — e.g. anything in docs/spec/ about statistics, totals, or the `headwater check`/`headwater explain` engine reading the whole corpus for numbers rather than caching them in a file like a manifest or lockfile.\\n- Report back with exact file paths, exact quotes, and decision/requirement identifiers (e.g. HW-DR-0054) so I can cite them precisely.\\n\\nKeep the report focused and include full relevant quotes rather than paraphrases, since I need to write prose that points at the exact ruling.\"}"

Any place where the engine computes a count over \\\"the whole corpus\\\" or \\\"every document\\\" — e.g., counts of identifiers, documents, obligations, findings, taxonomy terms, etc. Search engine/ source (Rust) for things like `.count()`, \\\"corpus\\\", \\\"whole corpus\\\", \\\"recompute\\\", \\\"computed at read\\\", struct/function names suggesting a corpus-wide aggregate.\\n2. Any docs/decisions/*.md or docs/requirements/*.md or docs/obligations/*.md file that explains WHY such a count is NOT committed to a file but instead recomputed whenever the corpus is read — i.e., a ruling about avoiding a committed derived count, staleness, or the cost/benefit of caching vs recomputing over a whole corpus.\\n3. Related concepts: \\\"derived artifact\\\", \\\"regenerate\\\", \\\"fold\\\" (mentioned in CLAUDE.md as \\\"derived fold\\\" with a merge driver), \\\".headwater/taxonomy.lock\\\", \\\".headwater/ids/\\\" claim store, identifier allocation needing \\\"scan every remote branch for the highest identifier in use\\\" (this is one example of a live corpus-wide computation — see CLAUDE.md's identifier claim store section and docs/decisions/0054-*.md).\\n\\nPlease report:\\n- The exact file path(s) and decision/requirement number(s) that state the ruling (if found) about why a corpus-wide count/scan is computed at read time rather than committed.\\n- Quote the key sentence(s) verbatim.\\n- If there are multiple candidates (e.g., identifier highest-value scan vs some other count like a document count, obligation count, word count, or taxonomy term count), list all candidates with their file paths so I can pick the most relevant one.\\n- Also check docs/spec/09-decisions.md and docs/process/decisions/ for anything relevant, and check DEVELOPING.md for \\\"What holds this repository\\\" section mentioning committed vs computed data.\\n\\nReport back concisely with file paths, doc numbers/titles, and verbatim key quotes.

I need to find a specific ruling/decision that establishes: a count taken over the whole corpus (some kind of corpus-wide tally, e.g. of documents, identifiers, obligations, etc.) is worked out (computed) at read time rather than being kept in a committed file (i.e., it's derived/computed on demand, not stored as a static committed artifact).\\n\\nPlease search thoroughly:\\n1. `docs/decisions/` and `docs/process/decisions/` directories - look for decision documents about derived vs. committed data, computed-at-read-time values, avoiding stale committed counts, corpus-wide aggregates, etc.\\n2. `docs/spec/` - especially anything about the engine, the graph, resolution, or corpus-wide facts.\\n3. Search for terms like: \\\"count\\\", \\\"corpus\\\", \\\"derived\\\", \\\"computed\\\", \\\"read time\\\", \\\"committed file\\\", \\\"stale\\\", \\\"regenerate\\\", \\\"fold\\\" (this repo has a concept of \\\"derived fold\\\" per .gitattributes merge driver mentioned in CLAUDE.md).\\n4. Look at `docs/decisions/0054-the-upper-bound-of-a-reconcile-first-allocator-is-the-corpus-and-a-claim-store.md` mentioned in the project's CLAUDE.md - it discusses scanning branches for highest identifier, which is somewhat related but may not be the exact ruling.\\n5. Search `.headwater/` directory structure, `docs/spec/` numbered parts for anything about \\\"count\\\" fields, statistics, or aggregate values in the taxonomy lock file or elsewhere.\\n6. Check DEVELOPING.md for \\\"What holds this repository\\\" section which may describe this design choice.\\n\\nI need the EXACT file path and identifier (e.g., HW-DR-XXXX or decision number) of the ruling that says corpus-wide counts must be computed at read time, not committed. Also quote the key sentence(s) from that document that state the reasoning (why: staleness, drift, reproducibility, etc.).\\n\\nAlso identify: is there an existing example in the codebase of such a count being computed at read time (e.g., a CLI verb like `headwater explain` or `headwater check` that counts something across the corpus)? Give file:line references if you find the implementation.\\n\\nReport back with: the ruling's file path and title, the exact quoted reasoning, and any implementation references. Keep it focused - I don't need a full repo tour, just this specific answer.\"}"
