A document may belong to an episode only while that episode is active in event time (ADR 0003). Membership cannot start before or end after the episode interval. Recovery is the computed share of containment flags that match known truth versus accepting every membership.

Complementary to #118 (`subevent_containment`: child event versus parent event). This crate owns episode-membership containment.

Local gates:

  • `cargo test -p episode_membership --all-targets` GREEN after RED (package did not exist)
  • clippy `-D warnings` PASS
  • workspace contract PASS
  • docstring contract PASS
  • lines 20/20; nightly-2026-08-01 branches 12/12

Does not allocate migration `0008`. Does not recreate `stopword_deletion` (#145), `psychometric_core` multilevel (#144), or other in-flight crates.

Keep this PR draft. Preferred merge remains #46 only when exact-head required Checks pass and a qualifying independent (non-Cursor/CodeRabbit) APPROVE exists. Do not empty-commit.

The recovery calculation can overflow for extremely large valid inputs, potentially causing a panic or incorrect recovery rate. The PR is otherwise mergeable with explicit owner awareness or follow-up to use a size-safe counter.

Current head 71ad631 merges protected main and fixes the previous exact-head CI root cause: repository rustfmt ordering in the episode-membership exports/tests. Focused proof passed: cargo fmt --all -- --check, cargo test -p episode_membership --offline (6 tests), workspace contracts, documentation validation, Rust docstring contract, and git diff --check. The exact-head Checks are rerunning; merge remains gated by one qualifying independent approval.

Current-head validation update (5a05b8f): fixed the quality contract to derive the Rust crate count from scripts/check_workspace_contract.py instead of hard-coding 10. Local evidence: 89 quality tests passed; coverage 100% (991/991 statements, 442/442 branches); workspace, docstring, documentation, and diff checks passed. Please review and rerun Checks against this exact head; merge remains subject to the repository's two independent approvals and protected rules.

Current-head review fix (ecaa8bc): Added the missing APA 7 Allen (1983) reference to the same standards-and-literature register as its in-text citation.

Exact-head failure RCA for ecaa8bc: Strix produced Vulnerabilities 0, then failed because the local Caido guest bootstrap could not connect to 127.0.0.1:48080. This is a central Strix runtime-infrastructure failure, not a source vulnerability. The narrow fail-closed classifier repair is in ContextualWisdomLab/.github#1181; do not treat this old failed run as a clean security verdict until the central fix is merged and this exact head is rerun.

Current exact-head triage: strix is the only completed failure on ecaa8bcbc8a5007f56e14c66806f3deccea525da; the job log reports bounded Caido guest bootstrap infrastructure failure (loginAsGuest could not connect to 127.0.0.1:48080) with no vulnerability finding. The root-cause repair is in ContextualWisdomLab/.github#1176; re-run this exact head after that protected central workflow change lands. No source workaround or bypass is warranted.

Current-head review refresh for ecaa8bc:

  • Episode membership is required to remain inside the episode interval, preserving event-time containment.
  • Local diff, documentation, workspace, docstring, and formatting contracts pass. All non-Strix checks are passing; Strix is the only current failure and the required coverage evidence remains pending.
  • The Strix failure is the known Caido guest bootstrap curl at 127.0.0.1:48080 with Vulnerabilities 0. Its canonical owner is ContextualWisdomLab/.github PR 1153, which is still open; rerunning unchanged TEPP source would reproduce the infrastructure defect.
  • No TEPP source fix or bypass was made; merge remains withheld until the central repair is merged, Strix is rerun on this exact head, and qualifying approvals exist.

Rebased current head 5419b0f onto origin/main. The changelog conflict retains both feature and current-main entries; inherited documentation trailing whitespace was removed. Local merge-tree, git diff --cached --check, and cargo fmt --all -- --check pass. Exact-head hosted checks and required independent approvals remain required before protected merge; the prior Strix infrastructure failure is tracked separately from TEPP source.

Current-head disposition for the Devin finding on 5419b0f: the full APA 7 Allen (1983) reference is already present in docs/research/standards-and-literature.md in the exact current tree, matching the episode-membership doctoring. The finding is stale and needs no source patch. Please refresh independent review for 5419b0f only; no approval or merge bypass is being issued.

Current-head maintenance update for exact head 58a5eae against protected main e65cd66. Normal restack completed; no force push or bypass was used. Removed tracked generated .codegraph/codegraph.db; .codegraph/.gitignore remains the only tracked CodeGraph artifact. Preserved the episode-membership contract: inverted windows fail closed, equal and contained boundaries pass, and recovery is compared with known truth. Exact merge-result local verification passed: workspace contract, Rust documentation contract, documentation validation, 140 Python quality tests, cargo fmt, workspace tests, clippy, release build, cargo doc, cargo deny advisories bans licenses sources, Rust line coverage 4927/4927 100%, and Rust branch coverage 1850/1850 100% with the repository-approved sqlx_live.rs exclusion. Secret-scan findings are unchanged pre-existing test fixtures and credential-shaped literals outside this change. Hosted Checks and independent review must be refreshed for this exact head; no approval or merge bypass is being issued. Decision: WAIT_AND_REMEDIATE.

🔴 Duplicate crate entry fails the contract tests

EXPECTED_CRATES lists episode_membership twice. test_live_repository_is_documented asserts the inventory has no duplicates and that its length equals the count of on-disk crate roots. Both assertions fail, turning the contract gate red.

🔴 Duplicated body in recovery-rate function breaks the build

identity_recovery_rate computes and returns the rate inline, then a leftover second copy of the computation follows that return expression. The inline Ok(...) has no semicolon before the following let, so the crate fails to compile.

📝 Info: Dangling duplicated README paragraphs

README.md gains several truncated, duplicated sentence fragments (e.g. "The workspace bounded crates compile independently but intentionally expose no") from the same merge that duplicated the crate registrations. Documentation cleanup, not a code bug.

📝 Info: Recovery-rate test values are consistent

The rewritten test derives recovered from refuse_membership_outside_episode and expects collapsed_rate of 2/3. The six cases split 4 contained / 2 escaping, so the all-true collapse matches 4/6 = 2/3, consistent with equal-bound containment.
