The reading is not that the criterion is loose: the +round-0 pool is Stage-1 *false positives* drawn from a masked negative substrate, and a 96-nt +element scoring 0.9977 that sits 19 bp upstream of an `alanine--tRNA ligase` is most plausibly +an uncatalogued T-box. ADR-0005 D14's spare rule exists precisely so those are spared rather +than trained against, and 541 of them now are. + +**⚠ THE BIGGEST DEFECT WAS FOUND BY DISBELIEVING A NUMBER, NOT BY A TEST.** The first run +returned **541 of 941 passing** and the per-CDS background density of D4's four classes is +**4.14 %** — an irreconcilable gap. The cause was that the downstream walk bounded the distance +only from above: a bacterial genome is ~88 % coding, so a window buried inside a long gene found +that gene as its "downstream" gene and inherited its identity. D4's class-II case genuinely +needs a *negative* distance (a translational T-box abuts/overlaps the start codon), so the fix +could not be "reject overlap"; it is that the CDS start must lie at or after the **element's own +5′ end**, which pins no new number. The corpus-level counts barely moved because Stage-1 +candidates land in leader regions rather than inside genes — so the number that exposed the bug +was not the number the bug corrupted. + +**⚠ TWO DEFECTS THE DIAGNOSTIC FOUND IN ITSELF, AND BOTH WERE SILENT ZEROS.** (1) The pseudogene +diagnostic reported **0** pseudogenized first-downstream ORFs corpus-wide, because the tandem +carve-out hops exactly the population the diagnostic exists to size; the counts now accumulate +across the whole walk (15 pseudogenized, 88 unjudgeable). (2) D4's hypothetical/pseudogene route +was **entirely unreachable**: `gff3.gene_identity_text` collects `Dbxref`/`Name` as well as +`product`, and on NCBI CDS those are accessions (`Dbxref` is present on 29,852 of 30,273 +measured CDS), so every `hypothetical protein` still had non-empty "identity text", never +resolved to unjudgeable, and was scored a *decided* `failed` instead of being routed to the +fallback. Identifier-shaped values are now filtered, with a positive control asserting the +filter removes identifiers rather than removing judgement. + +**⚠ THE VOCABULARY IS PRECISION-FIRST BECAUSE THE PERMISSIVE VERSION WAS MEASURED FIRST.** An +"amino-acid word + enzyme word" rule looks reasonable and swallows `HAMP domain-containing +histidine kinase` (38 CDS over 12 hosts, two-component signalling), `serine/threonine protein +kinase`, `glutamine amidotransferase` (purine/His/Trp — **not** tRNA-dependent transamidation), +`methylated-DNA--[protein]-cysteine S-methyltransferase` (DNA repair) and `peptide-methionine +(S)-S-oxide reductase` (protein repair). Every `EXCLUSIONS` entry was observed on this corpus +before it was written down, exclusions are applied **before** every include rule, and the +transamidation rules all require the literal `tRNA`. Two ordering corrections came out of the +audit: the curated product name outranks the gene symbol (`hisJ` is the histidine transporter's +binding protein in the enterics and **histidinol phosphatase** in Firmicutes), and the symbol +route fires only when the product name says nothing at all — consulting it otherwise put `PTS +galactitol transporter subunit IIB` into the transamidation class via `gatB`, `cytochrome C-552` +into transport via `cycA`, and `homocitrate synthase` into aaRS via `lysS`. 24 of 4,991 matches +came from that route and 3 of the 24 were wrong. + +**⚠ THE CONTIG BRIDGE IS BY IDENTITY, AND AN INDEX JOIN WOULD HAVE BEEN WRONG ON HALF THE +CORPUS.** A candidate's contig is `:c`, an index into the genomic FASTA's record order; a +GFF's `seqid` is the NCBI contig accession. **23 of the 48** candidate-carrying annotated hosts +serve their GFF seqids in a different order than their FASTA records, so `records[ci]` ↔ +`seqids[ci]` would silently read the wrong contig on ~48 % of hosts. The id join resolves +**134 of 134** needed (host, contig) pairs. + +**Three gaps reported rather than papered over.** (1) The **shipped §9.1 decoy rows carry +coordinates on 0 annotated production hosts** — `decoys_v0`'s three non-structured pools have no +accession at all, its 2,999 `structured_rna` accessions are Rfam source contigs, and +`mining_pool_v0`'s 45,988 leader/trail windows sit on the TBDB source genomes — so that arm is +`available: false` **with its counts**, and the §9.1 leader class is re-instantiated inside the +annotated corpus instead (5′UTR and tRNA-adjacent windows). (2) The **false-FAIL arm has almost +no positive denominator**: only **2 TBDB records on 1 assembly** intersect the 339, because the +production substrate is by construction a negative one. (3) The **joint a ∧ b ∧ c arm is +structurally unavailable** — (b) has no backend until P3-15′-d — and is withheld, never computed +from two unavailable disjuncts. + +**Per-clade exclusion is the clade-structured cap D4 commissioned, and it is large.** 31.8 % +of candidates are `unavailable` (286 host-unannotated, 11 unjudgeable, 2 contig-absent), with +five phyla at **100 %** exclusion (Chloroflexota, Desulfobacterota, Fibrobacterota, Thermotogota, +Bdellovibrionota_C), Bacillota at 38.5 %, and Atribacterota / Sysuimicrobiota / Fusobacteriota at +0 %. That is the recall cap the commissioned bakta/prokka arm exists to lift. Empirical passing +distances: p50 117 bp, p95 269 bp, p99 364 bp, max 454 bp — all inside D4's 500 bp pad, which is +the sensitivity check D4 asks for. + +**⚠ `n_mined` IS STILL STRUCTURALLY 0.** Sparing is a disjunction so mining is a conjunction: +`relaxed_architecture` remains the one unavailable backend, so `max_possible_yield` still caps +the round at 0 until P3-15′-d lands. This step removes one of the two blockers, not both. diff --git a/reports/p3/synteny_exclusion_diagnostic.json b/reports/p3/synteny_exclusion_diagnostic.json new file mode 100644 index 00000000..4cd013ab --- /dev/null +++ b/reports/p3/synteny_exclusion_diagnostic.json @@ -0,0 +1,274 @@ +{ + "adr": "ADR-0006 D4 (criterion (c));

=?UTF-8?q?nd=201=20=E2=80=94=20the=20tandem=20carve-out=20now=20reaches?= =?UTF-8?q?=20the=20decision,=20not=20just=20the=20search?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 20 findings (CodeRabbit app 5, CLI 15), all real, 8 major, one in common. MAJOR - the carve-out was selectively broken. resolve_downstream_gene selected its target with the RE-ANCHORED window but returned that target's ELEMENT-RELATIVE distance, which synteny_status judged against the 500 bp pad. So D4's tandem carve-out fired only where it was not needed and turned the tandem loci it exists for into false FAILs. DownstreamGene now carries both distances; criterion_c sees decision_distance_bp. Five candidates move failed -> passed (541 -> 546 / 96 failed / 299 unavailable). The prior test asserted the walk reached the right gene - always true; the search was never wrong, the decision was. MAJOR - the distance statistic counted evaluations that did not pass. It collected every strand detail whose CLASS was passing without checking its STATUS, so out-of-window hits that FAILED were counted: 554 entries with a 1,652 bp max in a block documented as "measured on the passing candidates" against 541 passed. Now filtered on the detail's own status, and reported as two series - element-relative and the re-anchored decision distance. Decision distances: p50 117 / p95 266 / p99 356 / max 454, all inside the pad; the element-relative max is explained by n_passed_via_tandem_carve_out: 5. CORRECTION - a number reported from a superseded run. The PR body, the previous commit message and the dev-log quoted p95 269 / p99 364 / max 454 (n 549). The committed artifact said p95 272 / p99 389 / max 1652 (n 554): the field was read before the identifier-filter fix and not re-read after regenerating. MAJOR - the produced table was never read by either round. Both reviewers found it independently. --synteny-status is now wired into both apply-spare-rule legs, and declaring the backend without a table (or supplying one without declaring it) raises - the same answer apply_remine_spare_rule's probe_set already got. MAJOR - a committed provenance record named an absolute /home// path. Out-of-repo inputs are hashed and recorded as {name, sha256} instead. MAJOR - a test that could not catch the trap it named. test_no_clause_reads_dvc_tracked_data derived against REPO_ROOT, so on any checkout with dvc pull run a DVC clause would read True and it would still pass. It now derives against a tmp_path root holding only the SUPPLY_CLAUSES files. TWO ARTIFACT-PINNING TESTS WENT GREEN UNDER SABOTAGE. The distance-statistic and provenance tests read the COMMITTED report, generated by the fixed code, so breaking the source could not reach them. TestDiagnosticsComputedNotJustCommitted now calls the report builders directly. Both new tests bite. Also: the unavailability reason scanned both strands under a single-strand policy; merge_status_tables passed two inputs through unvalidated and accepted an empty shard; _upstream_window bounded the plus arm but not the minus; combine_strand_statuses raised a bare KeyError; load_contig_ids raised IndexError on a bare ">" header; synteny._gene_symbols was private while the producer's control arm depended on it; the candidate_evidence docstring still said no synteny backend exists.

Counts across two rounds: 20, 7. MAJOR - the 5'UTR decoy arm sampled the CDS the positive-context arm is built from. A 5'UTR upstream of an aaRS in a real genome may itself BE a T-box leader, so counting it as a FALSE pass inflates the rate; excluding it stops the arm representing a random leader. Reporting one reading only would be a choice disguised as a measurement, so both ship: over all CDS the arm reads 5.28%, over CDS naming none of D4's four classes it reads 0.35%. MAJOR - the sub-threshold hop could skip a CDS that already satisfied the criterion. The docstring already claimed the carve-out fires only on an ORF that cannot carry the criterion either way; the length branch did not enforce it. NO candidate verdict changed on this corpus - the case does not occur here - so this is latent correctness the new test pins, recorded as such rather than dressed up as a fix that moved a number. MAJOR - my CLI-reachability test was vacuous. It parsed [..., "--synteny-status", "t.json", "--help"] and asserted exit 0, but argparse handles --help BEFORE rejecting an unknown option, so that exits 0 for a flag the parser has never heard of (verified by execution). mine_round.build_parser was extracted so the assertion is structural, plus a negative control that the option set can answer False. MAJOR - exclusion_reason_totals broke the closed reason vocabulary. It fell back to "" while the per-clade breakdown fell back to host_unannotated for the SAME row. Both now read one derivation, which raises on an unknown reason. MAJOR - the merge did not preserve the shard-recorded hmm_fallback_available. config.as_dict() re-reads the LIVE constant, so a merge on a checkout where the flag had flipped would rewrite what the shards ran under. The shard-recorded value wins. MINOR - shipped_decoy_availability returned a partial shape when pandas is absent; a test asserted decision max_bp non-None but compared block max_bp without the same guard.

Impossible for a subset, and the giveaway that the two arms were INDEPENDENT DRAWS each capped at n_per_host rather than a population and its filter. The strict arm is now derived from the wide arm's own sample (strict_subsample), so the nesting holds by construction: 8,662 <= 9,090, rates 4.96% wide against 0.29% strict. The report's wording had claimed the nesting all along. MAJOR - two units in one report, unlabelled. The per-clade block sums to 941 CANDIDATES (546 + 96 + 299) while the distance block reported 554 STRAND EVALUATIONS - a candidate passing on both strands contributes two. Not a discrepancy, but a reader subtracting one from the other would conclude something was missing. Both blocks now carry an explicit unit and the report states 554 = 546 + 8. A THIRD ARTIFACT-PINNING TEST WENT GREEN UNDER SABOTAGE. test_the_utr_arm_is_reported_under_BOTH_readings reads the committed report, so breaking the derivation could not reach it - the same species as rounds 1 and 2. The filter is now a named function tested directly for the subset property, the identity of what it removes, and the all-D4 edge case. Three occurrences in one step: a test that reads a committed artifact validates the artifact, never the code that made it. MINOR - test_the_control_is_powered_and_says_why asserted powered and margin but not verdict, the field a reader consumes and the one that would go stale silently. MINOR - a decoys parquet missing its accession column raised a non-ProducerError, aborting the whole sweep AFTER every arm had been computed.

Counts across ten rounds: 20, 7, 4, 2, 1, 8, 1, 4, 3, 6. MAJOR - the control arm's 99.52% is a pass rate, and it was keyed false_pass_rate. Windows drawn upstream of a CDS already in a D4 class are SUPPOSED to pass, so that number is the control working - but under that key, any consumer reading every false_pass_rate in the file learns that criterion (c) false-passes almost always. The control now emits pass_rate + pass_rate_denominator; the decoy arms keep theirs. THE SIXTH ARTIFACT-PINNING MISS, AND THE SHARPEST. The sabotage for that rename was .get() instead of .pop() - COPY the key rather than move it - and the committed-report assertion stayed green, because the report it reads was written by the fixed code. The rename is now as_control_arm, tested for the three things that matter: the old key is removed (not duplicated), the counts survive, the source arm is not mutated. Six occurrences in one step, all the same shape: an assertion over a committed artifact cannot see a producer that writes the artifact correctly for the wrong reason. MINOR - the duplicate-key rule, a third time: load_clades collapsed a repeated assembly_accession, and a repeat with a different phylum would silently reassign every candidate on that host - the per-clade exclusion rate being the headline of the diagnostic. Verified against the real table: 2,500 assemblies still load. MINOR - the status table was parsed twice in the diagnostics branch (validate one snapshot, report from another); now parsed once via validate_status_payload.

Counts across eleven rounds: 20, 7, 4, 2, 1, 8, 1, 4, 3, 6, 6. MAJOR - Name=alaS on a hypothetical protein blocked the symbol fallback. gene_identity_text collects Name and gene alongside product, and a symbol like alaS is neither boilerplate nor identifier-shaped - so informative went non-empty and the classifier returned "no D4 class" BEFORE reaching the symbol route that exists for exactly that record.

A single <=8-character whitespace-free token is now treated as a name, not a description, with a positive control (DNA gyrase subunit A + gyrA must still decide None, or a filter that swallowed descriptions would pass alone). MINOR - the class-II overlap bound was off by one. The element's 5' edge is locus_start + 1 in 1-based coordinates, so a CDS starting on it is -(span - 1) away; >= -span admitted one coordinate before the element began, on both strands. MINOR - the overlap allowance leaked past the carve-out. D4's allowance is about the ELEMENT; once re-anchored, a CDS starting behind that anchor is not downstream of it, and criterion_c would read the negative distance as in-window. MINOR - the fail-closed supply derivation could CRASH on a malformed report root; a derivation that raises is not fail-closed. status_counts values are now type-checked too.

One host's candidates scattered across every shard, and _host_cache is created per run_shard call, so each shard re-parsed almost every host's GFF - turning one parse per host into n_shards parses per host, defeating the exact cache whose docstring says it is why the round takes seconds. shard_by_host now assigns whole hosts round-robin over their sorted order: deterministic and independent of manifest order. AND THE SHARD -> MERGE PATH IS NOW PROVEN END-TO-END, WHICH IT HAD NEVER BEEN. Three shards run separately and merged reproduce the single-shard table exactly - 941 verdicts, 546 / 96 / 299, status maps identical. The contract had only ever been exercised on synthetic two-row tables. MINOR - the distance series ignored strand_policy: it collected from any strand detail whose own status was passed, without checking whether the policy folded that strand into the candidate's verdict. Under plus/minus the other strand could contribute a distance describing a decision the round never made. The committed reports run under `both`, so no published number moves.

The fix that worked every time: **if the property is a relation, give the +relation a name and test the function, not the file.** Two adjacent species also appeared once +each: a test asserting the *wrong direction* of a correct fix, and a sabotage that was itself a +no-op (`tuple(t) is t`). + +**⚠ AND THE SECOND LESSON, FROM ROUNDS 16–18.** Three consecutive rounds found *"you fixed one of +two identical things"* — one of two sibling file reads, one of two path checks, one of two +`None` guards. **When a fix lands, grep for the other call site before declaring the class +closed.**
