The bounded ownership and callback repair at
Protected-copy evidence now includes three real Astra compaction/reply/cold-reopen cycles on one retained conversation and recovery/adoption, Astra reply and cold reopen on the second. Original content, same conversation identities, unique coverage and zero duplicate ingestion were preserved. The prior runtime also passed read/write compatibility on a candidate-touched disposable clone. Merge disposition: zero active source merge blockers and zero unresolved review threads on the last readback; the protected exact-head AI check and final live merge barrier remain required. Maintainer-authorized method is a merge commit pinned to this head, without bypass or auto-merge. The Eva recovery lane owns post-merge reconciliation, #457, release qualification and later installed-session acceptance. No issue closure, release or live installation is claimed here. |

Dropped findings before posting: 0. High-severity findings: 1.
Maintainer Analysis
Changed behavior:
- Conversation history and summary selection now use logical conversation ownership, including narrowly admitted blank-owner legacy rows.
- Same-session compression boundaries can reconcile replay cursors and renew compacted-snapshot proofs as new messages are appended.
- Compaction publication now validates source ownership across conversation producers and fails open when a required source occurrence cannot be mapped.
- Embedded archive references are expanded only when the entire content is an externalized placeholder.
Affected invariants:
- Durable owned context must remain reachable after session transitions.
- Summary lineage must cover each raw source without duplication or cross-conversation contamination.
- Replay proofs must not suppress genuinely new message occurrences.
- Publication must preserve contiguous, uniquely claimed source coverage.
Evidence:
- lifecycle_state.py:86-167 producer discovery and summary-root admission
- engine.py:4471-4490 logical-owner helpers
- engine.py:6642-6797 owned summary assembly and replay snapshot registration
- tests/test_owner_core_v12.py covers foreign ownership but not node-only producers aging out or overlapping legacy roots
Limitations:
- Review was limited to the supplied checkout diff; no shell commands, tests, builds, package scripts, or arbitrary PR code were executed.
- Callers and schema definitions outside the supplied diff were not inspected.
No-finding rationale: No additional issue was reported where the supplied diff did not establish a concrete supported-path invariant violation.
Risk Taxonomy
- Data loss: 1
- Migration: 1

Inline comments:
In `@compaction.py`:
- Around line 1143-1152: Update the duplicate-mapping fail-open branch around
_fail_open_after_publication_failure so it seeds fallback from working_messages
and assembles it with recovery_assembly_cap instead of an unbounded literal. Do
not mark context_is_assembled=True when the cap still requires overflow
recovery; preserve the capped recovery path for both leaf_passes and
non-leaf_passes.
In `@engine.py`:
- Around line 4493-4494: Update the ownership-root collection around
admitted_summary_roots to use the public SummaryDAG.connection property and
discard nodes whose get_node lookup returns None before returning the list.
Preserve sorting and ensure downstream consumers receive only existing summary
nodes.
In `@lifecycle_state.py`:
- Around line 144-149: Update the ownership proof used by
conversation_producers() and admitted_summary_roots() so explicit source rows
matching the current conversation establish ownership when no foreign explicit
rows are present, even without a current or last-finalized lifecycle binding. Do
not rely on passing producers alone; extend the relevant
unambiguous_legacy_session_ids() contract or add the necessary explicit-row
validation, while preserving rejection of mixed roots containing foreign
explicit sources.
- Line 129: Update the admission condition in the lifecycle-state root
validation flow to reject only missing or empty summaries, not zero or NULL
token_count values. Preserve source-ID validation, and handle zero or NULL
token_count as an accounting defect while ensuring valid descendants of node
parents remain associated with their lineage.

Validated inline findings: 1 (P0: 0, P1: 0, P2: 1, P3: 0).
Dropped findings before posting: 0. High-severity findings: 0.
Maintainer Analysis
Changed behavior:
- History, summary admission, compaction publication, and replay reconciliation now use logical conversation ownership across producer sessions.
- Same-session compaction boundaries can reconcile and renew exact compacted replay snapshots.
- Compaction fails open when a required source occurrence cannot be mapped uniquely.
- Embedded externalization references in native prose no longer replace the carrier content.
Affected invariants:
- Durable context must remain reachable across session rollover and legacy migration.
- Summary roots must have complete, non-overlapping, same-owner source lineage.
- Replay renewal must not duplicate, omit, or cross conversation boundaries.
Evidence:
- lifecycle_state.py:92-103 limits legacy producer admission to the lifecycle row's two retained bindings.
- lifecycle_state.py:105-190 rejects roots whose raw sources are not explicitly owned or admitted through that limited legacy set.
- store.py:797-816 uses the same limited legacy set for all conversation-history reads.
- tests/test_owner_core_v12.py covers A→B→A overlap but not loss of a producer older than
last_finalized_session_id.
Limitations:
- Review was limited to the supplied checkout diff; no commands, tests, builds, or arbitrary PR code were executed.
No-finding rationale: No additional correctness, security, CI, replay, or data-integrity defect was validated directly from the supplied diff.

Maintainer Analysis
Changed behavior:
- History, summary admission, publication checks, and mapping now use logical conversation ownership across producer sessions.
- Same-session compression boundaries can reconcile and renew compacted replay snapshots as fresh turns are appended.
- Embedded archive references in native prose no longer replace the full carrier content during replay.
- Compaction fails open when a required source occurrence cannot be mapped uniquely.
Affected invariants:
- Durable context must remain reachable across lifecycle rollover and legacy-data migration.
- Summary roots must have complete, non-overlapping, same-owner source lineage.
- Replay renewal must not duplicate, omit, or cross-contaminate stored occurrences.
Evidence:
- lifecycle_state.py:97 derives legacy candidates from only the lifecycle row's current and last-finalized session slots.
- lifecycle_state.py:102 passes only that bounded set to legacy ownership resolution.
- store.py logical-owner reads depend on the resulting legacy session set.
- tests/test_owner_core_v12.py covers one legacy-owner case and A→B→A overlap, but not retention across three or more producer generations.
Limitations:
- No tests, builds, scripts, or arbitrary PR code were executed, per review constraints.
- Review was limited to the supplied diff; broader checkout inspection was unavailable without prohibited shell access.
No-finding rationale: No additional defect was validated from the supplied diff with sufficient current-path evidence.

Maintainer Analysis
Changed behavior:
- Conversation-owned raw history and validated summary roots now span producer-session rollovers.
- Legacy blank ownership is promoted transactionally before lifecycle pointers move.
- Same-session compression replay can reconcile and renew persisted replay snapshots.
- Embedded archive references no longer replace native carrier prose unless the entire content is an externalized placeholder.
Affected invariants:
- Owned summary coverage must remain reachable across arbitrary lifecycle rollovers.
- Independent summary roots must never claim the same stored occurrence.
- Replay reconciliation must neither duplicate nor omit durable occurrences.
- Ambiguous or foreign legacy rows must not be attributed to the active conversation.
Evidence:
- lifecycle_state.py:90-101 bounds summary candidates to raw-message producers and two lifecycle pointers.
- lifecycle_state.py:104 onward validates and detects overlap only among the candidates returned by that bounded producer set.
- engine.py changes make cross-producer owned roots eligible for condensation, making summary-only intermediate producers relevant.
- The added rollover test preserves a raw-producing A root but does not cover an intermediate producer that owns only a parent summary.
Limitations:
- Review was limited to the supplied checkout diff; the final test-file patch was truncated.
- No shell commands, tests, builds, package scripts, or PR code were executed, as requested.
No-finding rationale: No additional issue was reported because the remaining concerns could not be validated from the supplied diff strongly enough to justify a finding.

Maintainer Analysis
Changed behavior:
- Compaction and reconciliation now operate on conversation-owned history across producer sessions while admitting only unambiguous legacy blank-owner rows.
- Lifecycle transitions promote proven legacy ownership atomically before replacing lifecycle pointers.
- Summary assembly and publication validate complete owned lineage and reject overlapping historical roots.
- Same-session compression replay can reconcile and renew exact snapshot proofs without duplicating appended turns.
- Embedded archive references in ordinary prose are no longer treated as whole-message externalized placeholders.
Affected invariants:
- Raw context remains stored when ownership or summary lineage is ambiguous.
- Conversation ownership must not cross session/profile boundaries.
- Compaction publication must cover every owned occurrence through its frontier exactly once.
- Replay reconciliation must preserve occurrence identity and avoid duplicate ingestion.
- Externalized payload restoration must not replace native carrier prose.
Evidence:
- compaction.py required-occurrence mapping and conversation-owned exclusion scan
- engine.py owner-history access, same-session boundary reconciliation, atomic snapshot renewal, and owned summary assembly
- lifecycle_state.py legacy-owner promotion, lineage admission, and publication validation
- reconcile.py exact snapshot-prefix ownership checks and whole-placeholder restoration guard
- store.py conversation-owned history query
- tests/test_legacy_bind_v18.py
- tests/test_native_carrier_replay.py
- tests/test_owner_core_host_callbacks.py
- tests/test_owner_core_v12.py
Limitations:
- Review was limited to the supplied checkout diff; the final test-file patch was truncated in the prompt.
- Per instruction, no shell commands, tests, builds, package scripts, or executable PR code were run.
- Remote CI status and behavior outside the shown diff were not verified.
No-finding rationale: The inspected changes consistently fail open on ambiguous ownership or lineage, retain raw data, bind replay proofs to exact owned snapshots, and include focused regression coverage for the primary lossless-history and replay risks. No concrete current-diff defect meeting the finding threshold was validated.

Learning: In `engine.py`, do not treat `SummaryDAG.get_node()` returning `None` after `admitted_summary_roots()` as a supported concurrency defect without proving a reachable summary-node deletion path during active assembly or condensation. Background rollup maintenance does not delete summary nodes; reset deletion uses the exclusive lifecycle boundary; and opt-in doctor cleanup protects the active binding. Silently omitting an admitted root requires a preservation proof because LCM summary lineage is lossless.

Learning: In `lifecycle_state.py`, blank legacy `messages.conversation_id` occurrences require an unambiguous durable lifecycle binding. Explicit same-conversation rows from the same producer do not prove ownership of a blank legacy occurrence. `unambiguous_legacy_session_ids()` and `admitted_summary_roots()` must reject a mixed root when this durable proof is absent.

Document the positive ownership predicate.
LifecycleStateStore._promote_bound_legacy_rows derives candidates from the target lifecycle state's current_session_id and last_finalized_session_id. unambiguous_legacy_session_ids requires that durable target binding before checking foreign bindings or rows. An explicit row for the target conversation does not prove ownership of separate blank rows, so an operator may assign mixed legacy data to the wrong conversation.

+ The binding must be unambiguous: another conversation binding or any explicitly

Thanks for the extensive investigation and the retained-conversation evidence here. The defects this PR targets (end-flush re-ingest after in-place compaction, finalized-checkpoint loss on reopen, and publication conflicts across compaction) were fixed on main a different way in v0.24.0/v0.24.1: #484 (compaction commit proof and same-id finalized-frontier resume), #462, #498, #504 and #510/#515. #247 is closed. Closing as superseded. If a retained-conversation case still fails on current main, please open a fresh issue with a reproduction against v0.24.1, and a new PR against main if one is needed. |
Retained conversations can fail compaction when different conversations share a producer session, or replay stored rows when Hermes ends the original history after an in-place compaction. Source selection and publication used different ownership domains, and the end hook reused a cursor from the shortened projection. Reopening a finalized session could also discard its committed checkpoint.
This change uses one owner domain for source selection, publication and summary-root admission. Ordinary replay remains scoped to the current producer and owner. It restores a finalized checkpoint only for the same session with no reset, reconciles an original-history end flush after an exact cached-prefix match, and recognizes trusted engine-produced snapshots without requiring a system message. Generated summary carriers receive the existing Hermes marker. Exact retained-user proof survives until that occurrence leaves the active projection. Externalized content resolves only when the entire message is a placeholder.
After a fresh turn, the causal writer renews an existing exact snapshot only when the owned prefix is proven and the complete ordered suffix was appended without filtering or lossy identity. The proof and new rows commit together. The reconciled cursor and existing store lock prevent a stale boundary or concurrent read from creating an invalid renewal; missing readback preserves fresh ingestion and declines renewal.
Related to #247. The broader candidate in #458 remains frozen as a draft. This change adds no schema, metadata registry, generic cold-reader snapshot-extension inference, cancellation protocol or host API.
Validation at
cb1dc6932d14f9e630fc173b84f822e644a9d9f7:Ownership and finalize/reopen defects have failing unmodified-baseline fixtures and passing corrections.
The original-history end-flush fixture reproduces the released baseline failure: 121 stored rows become 160. System and systemless variants now add zero rows through compaction, end flush, same-session boundary and cold replay; fresh turns are admitted once.
Focused owner, frontier, lifecycle, retained-occurrence and callback checks pass, including direct post-compaction assistant append, missing readback, fresh repeated content/tool pairs and joint append/proof rollback. Independent preservation review covers the final production delta.
Exact-head CI passes Python 3.11–3.14, lint and workflow lint.
Three real Astra pressure → compaction → reply → cold-reopen cycles passed on a protected retained-conversation copy through Hermes
21091eb43914d7268239e0991563a7be861bc226. Context reduced from 210,091 to 41,999 tokens, 209,541 to 44,353, and 210,035 to 48,816. Each committed genuine LCM coverage, preserved all original rows and the exact recent 24-message tail, and added zero duplicate rows through compaction, session end and both cold reopens. Base Astra used a 272,000-token window; native fallback was disabled. Existing normal mode was used with threshold full sweep disabled.A second retained-conversation copy also passed guarded recovery/adoption (52,978→45,954 tokens), an actual Astra reply and cold reopen with all five summary roots visible and zero duplicate ingestion. Every original source row remains; a malformed tool interval was genuinely summarized before retaining its protocol-valid 12-message raw suffix. This one-off recovery does not replace standard 24/32-tail regression gates.
The prior Hermes/LCM runtime read and wrote a candidate-touched disposable clone while preserving original content.

c6a1246b3f05191a0ca10e1d12173c167563e235additionally:Each changed surface has focused regression evidence and independent targeted acceptance/adversarial coverage. The predecessor d1 passed all required CI jobs; final c6 exact-head CI and protected review receipts are being checked. The copied provider evidence above remains bound to cb1 and is not automatically requalified at c6.
Late review claims were bounded and dispositioned: post-reset restoration is a preexisting excluded-path limitation; normal compression rollover already reassigns every node; the alleged fresh-ingest loss did not reproduce on the actual baseline overlap database, which has no registered compacted-active snapshot premise. No global node scan, producer registry or speculative renewal mechanism was added.
Separately, #457 has passing synthetic actual-Hermes cancellation/cold-retry/save checks for raw and existing-summary inputs, including fresh repeated tool pairs. The combined candidate passes 34 affected checks, but that interruption change is not part of this PR. RC/GA qualification and live installation remain incomplete. Existing service uses the native recovery workaround; this PR does not claim the installed LCM is repaired. No release or issue closure is claimed.
