+  # SINGLE-PASS FILING (2026-10-07, Nick's first-time-correct directive):
+  # the old design ran TWO jobs on submission — priority-gate (which saw
+  # no P-label and posted the ⚠️ warning) and auto-label (which inferred
+  # and applied the P-label). The gate ran BEFORE the inference that
+  # would have made the warning unnecessary: every keyword-inferrable
+  # submission ate a spurious warning, a flag add/remove cycle, and a
+  # wasted workflow run. The fix is ORDER: infer → apply → THEN gate.
+  # A submission whose priority is inferable gets its P-label in this
+  # same run; the warning fires only when inference genuinely produced
+  # nothing (a true filing gap, not a race the robot loses to itself).

+# SUPERSESSION REPORT — programmatic evidence
+_Created 2026-10-07. Question: is curator superseded by memory_consolidation? Can supersession be determined programmatically?_
+
+## Answer in one paragraph
+
+No — they are NOT supersessions of each other. They are two different machines in one pipeline: **memory_consolidation compresses what already exists** (warm neurons, graph entities, abstraction facts → consolidated knowledge records), while **curator gates what gets written** (evidence → worthiness filter → graded routing → tiers). Both are wired into sleep_time's nightly run: consolidation runs in-process, curator runs as a subprocess. The real finding is darker: **curator has NEVER successfully run in production** — three of its four dependencies were never ported from the Odysseus branch, so every invocation died at import. Both diagnoses were reached programmatically.
+
+## The programmatic supersession test (reusable)
+
+Six signals, each binary and evidence-based (`/tmp/ss_engine.py`, promote to scripts/):
+
+| Signal | Test | Weight |
+|---|---|---|
+| R1 Import graph | production importers vs canary-only importers | high |
+| R2 Subprocess summon | module executed as a script by another module | high |
+| R3 Output artifacts | documented output files exist with recent mtimes | high |
+| R4 Function overlap | name overlap with the suspected successor | low (weak signal) |
+| R5 Importability | `import X` succeeds (phantom dep = dead) | gate — fails = dead regardless |
+| R6 End-to-end probe | documented entry path executes with real input | decisive |
+
+## Applied to curator vs memory_consolidation
+
+| Signal | curator | memory_consolidation |
+|---|---|---|
+| R1 | 0 production importers | 2 (memory_selector, sleep_time) |
+| R2 | summoned as script by sleep_time + dependency_tracker | summoned by dependency_tracker |
+| R3 | **index/blocks_meta.json DOES NOT EXIST — no journal files — never wrote output** | graph.sqlite exists but **stale (Aug 22)**; consolidation/*.json never created |
+| R4 | 2% overlap — different function sets (confirms: different jobs) | 2% |
+| R5 | importable NOW (after repair); dead since #314 | importable |
+| R6 | dry-run probe NOW green (post-repair); was JSONDecodeError-crash | consolidate() wired, but its outputs absent too |
+
+## Verdict
+
+1. **NOT a supersession.** 2% function overlap + different roles: curator = write-path gate (worthiness → grade → tier), memory_consolidation = read-path compressor (existing memories → knowledge records). One writes, one compresses. Both belong.
+2. **Both are broken in production.** Curator never ran (phantom deps). memory_consolidation's outputs are stale/absent — its last graph write was Aug 22. The whole sleep-time memory pipeline has been quietly degraded.
+3. **Disposition: REPAIR, not retire.** grading.py + worthiness.py are now recovered from the Odysseus source branch (provenance, not reconstruction) with frozen tests; curator's dry-run executes end-to-end. Remaining phantom for curator: lexicon_evolution (guarded — degrades), aaak (guarded — optional compression). Both degradable, not blocking.
+
+## The phantom-import census (the general finding)
+
+16 phantom imports found across src/rune. The important ones:
+
+| Module | Importers | Guarded? | Disposition |
+|---|---|---|---|
+| worthiness | curator | NO (hard crash) | ✅ RECOVERED from Odysseus + frozen tests |
+| grading | curator | NO | ✅ RECOVERED from Odysseus + frozen tests |
+| lexicon_evolution | curator | yes (degrades) | recover-or-rename decision needed |
+| aaak | curator, memory_store, warm_router | yes | optional compression; recover or accept degrade |
+| build_pipeline_policy | prompt_sync | NO | phantom — prompt_sync is dead on arrival |
+| gitea_auth | forge | NO | forge.py dead; is forge itself superseded? |
+| faster_whisper, pynput | voicebox | yes | optional deps — correct as-is |
+| research_lens | claim_audit | yes | lives in ~/.config/opencode/scripts — cross-repo dep |
+| ep_loader | 5 modules | false positive | resolves via sys.path hack to src/rust/ |
+| autonomy_loop, cognitive_loop, dream_cycle | rune_tui | yes | TUI plugins — recover or retire |
+| commitments, dedupe_policy, local_memory | warm_router, memory_store, sleep_time | yes | recover-or-accept-degrade |
+
+**Hard-crash phantoms mean the owning module is dead code:** prompt_sync, forge, and (until today) curator.
+
+## What the dictonomy rebase inherits
+
+The Go/Rust port queue should SKIP dead code until its disposition is decided. A module that never ran has no behavioral parity to prove — porting it would faithfully reproduce a ghost. The audit instrument now needs an R5 importability column so dead modules are marked before they're counted.

+"""dichotomy_audit.py — the honest completion instrument for the dichotomy rebase.

+Function-level, not directory-level: a module counts as covered only when its
+PYTHON FUNCTIONS have identifiable counterparts in the Go/Rust implementation.
+A Go directory with 3 structs and none of the module's 70 functions is a
+facade, and this audit names it as one.
+
+Matching rule (name-preserving ports): a Python function name matches when
+its snake_case form, or its Go/Rust camelCase/PascalCase form, appears in the
+candidate implementation sources. Deliberately strict — novel Go names that
+don't echo the Python names do NOT count, because unverifiable "trust me,
+it's in there somewhere" is exactly the failure mode this instrument exists
+to kill.

+"""Constitution-grounded worthiness filter.
+
+The constitution is the backbone for how the assistant interacts, AND any
+information absorbed into memory should influence thinking, responses, and
+personality. But there must be a FILTER that asks whether a candidate is worth
+adding to this infrastructure at all — judged by whether it moves toward the
+goal of being a personal assistant, per the constitution.
+
+This module is the "is it worth it" gate. It runs AFTER graded routing (what
+tier the fact belongs in) and BEFORE apply (whether it earns its place). Each
+constitution inviolable contributes a question the candidate must answer.
+
+Verdicts:
+    ABSORB      — worth keeping in the tiers (cold/warm storage; improves the
+                  assistant's thinking and recall). No hot-block write, but it
+                  is retained and can influence future reasoning.
+    PROMOTE     — worth absorbing AND strong enough to shape responses /
+                  personality via the normal evidence-gated curator path
+                  (operating/persona require strength >= thresholds anyway).
+    DEFER       — not clearly valuable; park in the candidate ledger / journal,
+                  no write this run. Re-review if it recurs.
+    REJECT      — actively harmful to the goal (violates a constitution
+                  inviolable: dishonest, hustle-framed, harms the production/game
+                  environment, overclaims, ignores material reality). Never absorbed.
+
+Every verdict carries the QUESTION ANSWERS so the reason is auditable — the
+journal entry shows WHY, not just the decision.
