The federation-architecture lead I have been walking the federation-grain replay-rubric run cluster with through the spring 2026 cycle hit the structural shape of the per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule the same week blog 227 closed, when the federation's first per-record-type-partitioned acknowledgement-retention record (the post-fix rollup-ack-failed acknowledgement-retention composition the federation-architecture lead landed against the dispatch-lane-critical-dominant lane's tier-multi-annual retention disposition at 1100 days from blog 227's debugging story, with the per-record-type-partitioned retention composition rule reading the joint composed-ack-state-and-dispatch-lane composition correctly against the structurally bounded one-record-per-dispatch-acknowledgement retention horizon) needed to land against the federation's annual review-pass cadence with a structural per-annual-cycle rollup record, and the lead's first-cycle assumption that the per-record-type-partitioned acknowledgement-retention record could roll up against the federation's annual review-pass cadence by reusing blog 222's per-quarter acknowledgement-rollup composition rule directly (one acknowledgement-rollup record per per-quarter cadence cycle, with the per-tier joint rollup-aggregation composition function reading each retention-tier independently against the federation's per-quarter cadence horizon) turned out to be the structurally fragile assumption blog 227's closing paragraphs left open. The per-record-type-partitioned acknowledgement-retention record is not a per-quarter acknowledgement-rollup record and the annual rollup reading for it is not a per-quarter rollup reading. The acknowledgement-retention record reads at the rollup-trend-layer-grain with a per-retention-tier disposition (one of four structural tiers per blog 227: tier-transient, tier-quarterly, tier-annual, tier-multi-annual), the four structural retention tiers each carry a structurally distinct annual rollup horizon reading against the federation's annual review-pass cadence and the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon jointly, and the joint reading of the retention-tier reference against the acknowledgement-retention record's composed_ack_state is the structural surface blog 222's per-quarter acknowledgement-rollup composition rule cannot land alone at the annual cadence horizon.
This post is the structural sketch of the federation-grain replay-rubric run's per-quarter rollup-trend-layer archival schema's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule against the federation's annual review-pass cadence: the per-annual-cycle rollup tuple shape that folds blog 227's per-record-type-partitioned acknowledgement-retention record into a structurally bounded per-annual-cycle rollup record, the per-retention-tier-partitioned annual rollup composition rule that composes the annual rollup record through a joint retention-tier-and-composed-ack-state annual rollup composition rule against blog 222's per-quarter acknowledgement-rollup composition rule, and the per-annual-cycle rollup decision rubric that reads the annual rollup record against the federation's annual review-pass cadence with a per-retention-tier-partitioned annual rollup decision against four structural per-annual-cycle rollup tiers. The post composes against blog 203 (the federation-grain quarterly review pass), blog 207 (the deterministic control layer for agents), blog 209 (the federation-grain seven-axis stack), blog 210 (the federation-grain replay-rubric run), blog 211 (the multi-quarter cost-amortisation), blog 217 (the per-axis revision-impact rollup form's archival schema and per-quarter trend layer), blog 218 (the per-quarter trend-layer drift-attribution composition rule), blog 222 (the per-quarter acknowledgement-rollup composition rule this post composes against), blog 226 (the per-record-type-partitioned dispatch-acknowledgement composition rule), and blog 227 (the per-record-type-partitioned acknowledgement-retention composition rule this post composes the annual-rollup-side surface against). The post sketches the per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule and blog 222's per-quarter acknowledgement-rollup composition rule through six structural moves: the per-annual-cycle rollup tuple's record shape against blog 227's per-record-type-partitioned acknowledgement-retention record, the per-retention-tier-partitioned annual rollup composition rule against blog 222's per-quarter acknowledgement-rollup composition rule, the per-annual-cycle rollup decision rubric against four structural per-annual-cycle rollup tiers, the annual rollup disposition's interaction with blog 211's multi-quarter cost-amortisation pattern and LA-085's application-execution-layer per-rule attribution-drift root-cause composition rule jointly, a debugging story that surfaces the structurally fragile per-quarter-rollup-direct-reuse failure mode the federation-architecture lead landed against the first run of the annual rollup composition rule, and the per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup's production-side cost and storage surface. The post forward-references blog 229 (the federation-grain replay-rubric run's per-quarter rollup-trend-layer drift-attribution archival-schema annual-rollup-trend composition rule against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon, the next-in-cluster post composing the cluster's multi-annual-cadence surface) and LA-085 (the application-execution-layer annual review-pass refinement structural-cause attribution refinement series part two, the article-pair shipped in this same run).
Why the Per-Quarter Rollup-Trend-Layer Drift-Attribution Archival-Schema Annual Rollup Composition Rule and Blog 222's Per-Quarter Acknowledgement-Rollup Composition Rule Are the Annual-Rollup-Side Operational Levers at the Federation's Annual Review-Pass Cadence
The federation-grain replay-rubric run's per-quarter rollup-trend-layer archival schema's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule and blog 222's per-quarter acknowledgement-rollup composition rule are the annual-rollup-side operational levers the federation-architecture lead reads against to land four structural surfaces the per-quarter rollup-trend-layer drift-attribution acknowledgement-retention records blog 227 sketched cannot land on their own against blog 222's per-quarter acknowledgement-rollup composition rule. The first surface is the per-annual-cycle rollup record surface: the federation has no structural read against which the acknowledgement-retention record composes into a structurally bounded per-annual-cycle rollup record per federation per annual review-pass cycle unless the lead can fold the acknowledgement-retention record's retention_tier, composed_ack_state, and dispatch_lane reference into a per-annual-cycle rollup record that reads the retention-tier reference jointly through a per-retention-tier-partitioned annual rollup composition rule against blog 222's per-quarter acknowledgement-rollup composition rule.
The second surface is the per-annual-cycle rollup composition surface: the federation has no structural read against which the per-annual-cycle rollup record composes against blog 222's per-quarter acknowledgement-rollup composition rule with a per-retention-tier-partitioned annual rollup decision per retention-tier target unless the lead can compose the rollup record through a joint retention-tier-and-composed-ack-state composition rule that produces a structurally bounded per-annual-cycle rollup record per federation per annual review-pass cycle. The third surface is the per-annual-cycle rollup decision surface: the federation has no structural read against which the rollup record lands against the federation's annual review-pass cadence with a per-annual-cycle rollup tier unless the lead can compose the rollup record through a per-annual-cycle rollup decision rubric that gates the rollup tier against four structural per-annual-cycle rollup tiers. The fourth surface is the per-quarter rollup-trend-layer drift-attribution archival-schema annual-rollup-trend surface: the federation has no structural read against which the rollup record composes against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon's per-quarter rollup-trend-layer drift-attribution annual-rollup-trend composition rule with a per-multi-annual-cycle rollup-trend record unless the lead can compose the rollup record through a per-quarter rollup-trend-layer drift-attribution archival-schema annual-rollup-trend composition rule (a surface blog 229 will sketch in the cluster's next post). The four surfaces compose into the federation-grain replay-rubric run's per-quarter rollup-trend-layer archival schema's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule and blog 222's per-quarter acknowledgement-rollup composition rule.
The Per-Annual-Cycle Rollup Tuple Shape
The per-annual-cycle rollup tuple is an eight-element per-annual-cycle rollup record composed against blog 222's per-quarter acknowledgement-rollup composition rule, structurally extending blog 222's six-element per-quarter acknowledgement-rollup tuple with a structurally extra per-retention-tier-partitioned aggregate element and a per-annual-cycle landing cadence horizon. The first element is the rollup identifier: the per-annual-cycle rollup record's structurally bounded UUID against the federation's annual review-pass cadence (analogous to blog 222's per-quarter acknowledgement-rollup record's rollup UUID), an approximately 36-byte UUID used by blog 229's archival-schema annual-rollup-trend composition rule to bind the rollup record to its downstream archival-schema annual-rollup-trend record.
The second element is the acknowledgement-retention reference set: blog 227's per-record-type-partitioned acknowledgement-retention record set's structurally bounded UUID references for every acknowledgement-retention record composing into the per-annual-cycle rollup record (per blog 227's seven-element acknowledgement-retention tuple's first element, the retention_id), reading the per-annual-cycle rollup record's structural parent set against the originating per-record-type-partitioned acknowledgement-retention composition records across the annual review-pass cycle. The acknowledgement-retention reference set is the per-annual-cycle rollup record's load-bearing traceability element: the federation-architecture lead reads the acknowledgement-retention reference set against the federation's per-quarter rollup-trend-layer drift-attribution acknowledgement archival schema to retrieve the originating acknowledgement-retention records' retention tier, composed acknowledgement state, dispatch lane reference, and retention window jointly across the annual review-pass cycle. The set's cardinality is structurally bounded against the federation's per-quarter cadence horizon multiplied by the federation's annual review-pass cadence: approximately one to four acknowledgement-retention records per federation per annual review-pass cycle (one per federation-quarterly-cycle per blog 226's per-record-type-partitioned dispatch-acknowledgement cardinality, multiplied by three to four federation-quarterly-cycles per annual review-pass cycle per blog 217's per-quarter trend layer cardinality).
The third element is the per-retention-tier-partitioned aggregate: a structurally bounded four-element aggregate reading the count of acknowledgement-retention records composed at each of the four structural retention tiers per blog 227 (tier-transient, tier-quarterly, tier-annual, tier-multi-annual). The aggregate is the structurally distinct element against blog 222's per-quarter acknowledgement-rollup tuple's per-tier-aggregate field: where blog 222's tuple carries a per-tier aggregate reading at the per-quarter cadence horizon, the per-annual-cycle rollup tuple carries a per-retention-tier aggregate reading at the annual review-pass cadence horizon, and the structural distinction is the load-bearing reason the annual rollup composition rule cannot reuse blog 222's per-quarter acknowledgement-rollup composition rule directly. The aggregate's structural composition reads approximately one-quarter of acknowledgement-retention records at tier-transient (lapsing before the per-annual-cycle rollup landing window opens), one-half at tier-quarterly (composing into the per-annual-cycle rollup at quarterly resolution), one-eighth at tier-annual (composing one-to-one with the annual review-pass cadence), and one-eighth at tier-multi-annual (carrying through to the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon per blog 211).
The fourth element is the per-composed-ack-state-partitioned aggregate: a structurally bounded four-element aggregate reading the count of acknowledgement-retention records composed at each of the four structural rollup acknowledgement states per blog 226 (rollup-ack-pending, rollup-ack-partial, rollup-ack-complete, rollup-ack-failed). The aggregate reads the per-annual-cycle rollup record's structural disposition source set against the originating acknowledgement-retention composition. The per-composed-ack-state aggregate is the structurally tight element against blog 222's per-quarter acknowledgement-rollup tuple's per-state-aggregate field at the rollup-trend-layer grain.
The fifth element is the per-annual-cycle rollup tier: the per-annual-cycle rollup record's structurally bounded rollup-tier disposition, one of four structural tiers (rollup-tier-lapsed, rollup-tier-quarterly-resolved, rollup-tier-annual-bound, rollup-tier-multi-annual-bound) composed against the per-retention-tier-partitioned aggregate and the per-composed-ack-state-partitioned aggregate jointly through the per-retention-tier-partitioned annual rollup composition rule the next section sketches. The sixth element is the per-annual-cycle rollup window in days: the rollup tier's structurally bounded rollup window in days, gated against the rollup tier per the federation's annual review-pass cadence (rollup-tier-lapsed reads a 30-day landing window aligning to the federation's structurally bounded transient horizon, rollup-tier-quarterly-resolved reads a 100-day landing window aligning to the federation's per-quarter cadence horizon per blog 217, rollup-tier-annual-bound reads a 365-day landing window aligning to the federation's annual review-pass cadence per blog 211, and rollup-tier-multi-annual-bound reads a 1095-day landing window aligning to the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon per blog 211's cost-amortisation sketch). The rollup window thresholds are sized against the four federation cadence horizons jointly.
The seventh element is the per-annual-cycle rollup landing timestamp: the timestamp at which the per-annual-cycle rollup record lands against the federation's annual review-pass cadence, structurally bounded against the federation's annual review-pass cycle close timestamp plus the rollup window's archival landing offset. The eighth element is the per-quarter-cadence aggregate vector: a structurally bounded three-to-four-element vector reading the per-quarter acknowledgement-rollup record references (per blog 222's per-quarter acknowledgement-rollup composition output) composing into the per-annual-cycle rollup record across the annual review-pass cycle's three-to-four federation-quarterly-cycles per blog 217's per-quarter trend layer cardinality. The vector is the load-bearing federation-architecture-lead traceability element across the annual review-pass cycle's structurally bounded three-to-four-federation-quarterly-cycles composition.

The Per-Retention-Tier-Partitioned Annual Rollup Composition Rule
The per-retention-tier-partitioned annual rollup composition rule is the structural composition function the federation-architecture lead reads against to compose blog 227's per-record-type-partitioned acknowledgement-retention records into a structurally bounded per-annual-cycle rollup record per federation per annual review-pass cycle. The composition rule reads the acknowledgement-retention record set's per-retention-tier aggregate and per-composed-ack-state aggregate jointly and produces one of four structural per-annual-cycle rollup tiers per per-annual-cycle rollup record.
The first per-retention-tier-partitioned annual rollup composition reads rollup-tier-lapsed: the per-annual-cycle rollup record composes into rollup-tier-lapsed when the per-retention-tier aggregate reads approximately greater than three-quarters tier-transient and the per-composed-ack-state aggregate reads approximately greater than three-quarters rollup-ack-complete jointly. The rollup-tier-lapsed disposition reads the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records lapsed before the per-annual-cycle rollup landing window opened, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record as structurally bounded against the federation's transient horizon. The disposition's structurally bounded landing window reads at 30 days per blog 211's one-third-per-quarter-cadence transient horizon sketch.
The second per-retention-tier-partitioned annual rollup composition reads rollup-tier-quarterly-resolved: the per-annual-cycle rollup record composes into rollup-tier-quarterly-resolved when the per-retention-tier aggregate reads approximately one-half tier-quarterly and approximately one-quarter tier-transient and the per-composed-ack-state aggregate reads approximately greater than one-half rollup-ack-complete jointly. The rollup-tier-quarterly-resolved disposition reads the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records resolved at the per-quarter cadence horizon, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record as structurally bounded against the federation's per-quarter cadence horizon. The disposition's structurally bounded landing window reads at 100 days per the federation's per-quarter cadence horizon per blog 217.
The third per-retention-tier-partitioned annual rollup composition reads rollup-tier-annual-bound: the per-annual-cycle rollup record composes into rollup-tier-annual-bound when the per-retention-tier aggregate reads approximately one-eighth tier-annual or greater and the per-composed-ack-state aggregate reads at least one rollup-ack-partial or rollup-ack-pending jointly. The rollup-tier-annual-bound disposition reads the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records bound to the federation's annual review-pass cadence, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record as structurally bounded against the federation's annual review-pass cadence. The disposition's structurally bounded landing window reads at 365 days per the federation's annual review-pass cadence per blog 211.
The fourth per-retention-tier-partitioned annual rollup composition reads rollup-tier-multi-annual-bound: the per-annual-cycle rollup record composes into rollup-tier-multi-annual-bound when the per-retention-tier aggregate reads approximately one-eighth tier-multi-annual or greater and the per-composed-ack-state aggregate reads at least one rollup-ack-failed jointly. The rollup-tier-multi-annual-bound disposition reads the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records bound to the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record as structurally bounded against the federation's multi-quarter cost-amortisation horizon. The disposition's structurally bounded landing window reads at 1095 days per blog 211's cost-amortisation sketch.

if transient_share > 0.75:
return PerAnnualCycleRollupTier.LAPSED

The composition rule is structurally bounded against the federation's annual review-pass cadence's per-quarter rollup-trend-layer drift-attribution acknowledgement archival schema, with the composition function reading the per-retention-tier aggregate and per-composed-ack-state aggregate jointly and emitting one of four structural per-annual-cycle rollup tiers per per-annual-cycle rollup record. The composition function's structural composition reads the per-retention-tier-partitioned aggregate's share distribution and the per-composed-ack-state-partitioned aggregate's failure-or-partial indicator jointly, with the structurally tightest disposition (rollup-tier-multi-annual-bound) gated against a structurally critical failure indicator at the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon.

The Per-Annual-Cycle Rollup Decision Rubric Against Four Structural Per-Annual-Cycle Rollup Tiers
The per-annual-cycle rollup decision rubric is the federation-architecture lead's structural rubric for reading the per-annual-cycle rollup record against the federation's annual review-pass cadence with one of four structural per-annual-cycle rollup tiers per per-annual-cycle rollup record. The rubric reads the per-annual-cycle rollup tier against four structural rubric dispositions per blog 227's four-tier per-record-type-partitioned retention composition rule's structural parallel.
The first per-annual-cycle rollup rubric disposition is rollup-rubric-archival-lapse: the structurally bounded archival-lapse disposition reading at rollup-tier-lapsed rollup tier, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records lapsing before the per-annual-cycle rollup landing window opens. The archival-lapse disposition is the federation-architecture lead's no-archival-binding lane against the per-annual-cycle rollup record: the per-annual-cycle rollup record composes a structurally bounded archival-lapse reading against the federation's transient horizon at 30 days per blog 211's one-third-per-quarter-cadence transient horizon sketch, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural archival-lapse disposition as the structurally lightest archival surface.
The second per-annual-cycle rollup rubric disposition is rollup-rubric-quarterly-cadence-bound: the structurally bounded quarterly-cadence-bound disposition reading at rollup-tier-quarterly-resolved rollup tier, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records resolved at the per-quarter cadence horizon. The quarterly-cadence-bound disposition is the federation-architecture lead's per-quarter-archival-binding lane against the per-annual-cycle rollup record: the per-annual-cycle rollup record composes a structurally bounded per-quarter-archival-binding reading against the federation's per-quarter cadence horizon at 100 days per blog 217, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural quarterly-cadence-bound disposition as the federation's per-quarter archival surface.
The third per-annual-cycle rollup rubric disposition is rollup-rubric-annual-cadence-bound: the structurally bounded annual-cadence-bound disposition reading at rollup-tier-annual-bound rollup tier, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records bound to the federation's annual review-pass cadence. The annual-cadence-bound disposition is the federation-architecture lead's annual-archival-binding lane against the per-annual-cycle rollup record: the per-annual-cycle rollup record composes a structurally bounded annual-archival-binding reading against the federation's annual review-pass cadence at 365 days per blog 211, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural annual-cadence-bound disposition as the federation's annual review-pass archival surface.
The fourth per-annual-cycle rollup rubric disposition is rollup-rubric-multi-annual-cost-amortisation-bound: the structurally bounded multi-annual-cost-amortisation-bound disposition reading at rollup-tier-multi-annual-bound rollup tier, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural disposition as the acknowledgement-retention records bound to the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon per blog 211's cost-amortisation sketch. The multi-annual-cost-amortisation-bound disposition is the federation-architecture lead's multi-annual-archival-binding lane against the per-annual-cycle rollup record: the per-annual-cycle rollup record composes a structurally bounded multi-annual-archival-binding reading against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon at 1095 days, with the federation's annual review-pass cadence reading the per-annual-cycle rollup record's structural multi-annual-cost-amortisation-bound disposition as the federation's multi-quarter cost-amortisation archival surface.
Interaction with Blog 211's Multi-Quarter Cost-Amortisation Pattern and LA-085's Application-Execution-Layer Per-Rule Attribution-Drift Root-Cause Composition Rule
The per-annual-cycle rollup record interacts with blog 211's multi-quarter cost-amortisation pattern through a structurally parallel multi-annual cadence composition: blog 211 sketched the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon at 1095 days as the structurally heaviest archival horizon the federation reads against, and the per-annual-cycle rollup record composes against blog 211's multi-quarter cost-amortisation pattern through the rollup-tier-multi-annual-bound rollup tier's structurally bounded 1095-day landing window. The structurally parallel reading composes the per-annual-cycle rollup record's rollup-rubric-multi-annual-cost-amortisation-bound disposition against blog 211's multi-quarter cost-amortisation horizon, with blog 211's cost-amortisation pattern reading the per-annual-cycle rollup record's structural multi-annual-cost-amortisation-bound disposition against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon's structurally heaviest archival surface.
The per-annual-cycle rollup record also interacts with LA-085's application-execution-layer per-rule attribution-drift root-cause composition rule through a structurally parallel federation-and-application-grain composition cascade: LA-085 sketches the application-execution-layer's per-rule attribution-drift root-cause composition rule against the application-execution-layer's annual review-pass cadence's next annual cycle's structural-cause attribution composition reading (the application-execution-layer's per-rule attribution-drift root-cause composition surface against LA-084's per-rule structural-cause attribution refinement composition rule), and the per-annual-cycle rollup record composes against LA-085's per-rule attribution-drift root-cause composition rule's per-rule root-cause surface through a federation-and-application-grain annual-cadence cascade. The cascade reads LA-085's application-execution-layer per-rule attribution-drift root-cause composition surface at the per-task grain (approximately 1700 per-task records per annual review-pass cycle per LA-078's distribution reading) and the per-annual-cycle rollup record's rollup-tier-annual-bound or rollup-tier-multi-annual-bound disposition at the federation-grain rollup-trend-layer grain (approximately 1 to 2 per-annual-cycle rollup records per federation per annual review-pass cycle), composing the federation-and-application-grain annual-cadence cascade's structurally critical annual-rollup-and-root-cause reading against the federation's annual review-pass cadence and the application-execution-layer's annual review-pass cadence jointly.

A Debugging Story: When the Direct Per-Quarter-Rollup Reuse Erased the Per-Retention-Tier Partition
In the first run of the per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule against the spring 2026 cycle's first per-annual-cycle composition window (the post-fix rollup-ack-failed acknowledgement-retention composition the federation-architecture lead landed against the dispatch-lane-critical-dominant lane's tier-multi-annual retention disposition at 1100 days from blog 227's debugging story, with the acknowledgement-retention record reading the joint composed-ack-state-and-dispatch-lane composition correctly against the structurally bounded one-record-per-dispatch-acknowledgement retention horizon), the federation-architecture lead's first-cycle assumption that the per-record-type-partitioned acknowledgement-retention record could roll up against the federation's annual review-pass cadence by reusing blog 222's per-quarter acknowledgement-rollup composition rule directly turned out to be the structurally fragile assumption blog 227's closing paragraphs left open. The lead's first-cycle reading composed the per-record-type-partitioned acknowledgement-retention record's annual rollup through blog 222's per-quarter acknowledgement-rollup composition function applied four times sequentially (once per federation-quarterly-cycle of the annual review-pass cycle's three-to-four federation-quarterly-cycles per blog 217's per-quarter trend layer cardinality), with each per-quarter rollup composition reading the acknowledgement-retention record's retention tier independently against blog 222's per-tier joint rollup-aggregation composition.
The first-cycle reading produced the following composed annual rollup disposition: the rollup-ack-failed tier-multi-annual acknowledgement-retention record from blog 227's post-fix debugging story landed in blog 222's per-tier joint rollup-aggregation composition's tier-multi-annual aggregate correctly for the structurally heaviest tier, but the per-quarter rollup composition produced four parallel per-quarter rollup records across the annual review-pass cycle's four federation-quarterly-cycles, each reading the acknowledgement-retention record as a structurally independent per-quarter rollup contribution. The four parallel per-quarter rollup records composed the federation's annual review-pass cadence's annual rollup surface with four structurally independent contributions per acknowledgement-retention record, structurally inflating the federation's annual review-pass cadence's per-acknowledgement-retention-record annual rollup footprint by a four-fold factor against the structurally bounded one-record-per-acknowledgement-retention-record annual rollup horizon the per-retention-tier-partitioned annual rollup composition rule reads.
The composed reading was structurally wrong on per-annual-cycle aggregate attribution: the per-record-type-partitioned acknowledgement-retention record is not four structurally independent per-quarter rollup contributions and the four federation-quarterly-cycles do not structurally compose four independent annual rollup contributions. The federation's annual review-pass cadence's annual rollup footprint at the four-fold-inflated reading was approximately 1600 to 2400 bytes per acknowledgement-retention record (four per-quarter rollup records times 400 to 600 bytes per record per blog 222's per-quarter acknowledgement-rollup storage footprint), where the structurally bounded one-record-per-acknowledgement-retention-record annual rollup horizon's per-acknowledgement-retention-record annual rollup footprint should have been approximately 380 to 520 bytes per acknowledgement-retention record. We measured the four-fold annual rollup inflation against the federation's first annual review-pass cycle of acknowledgement-retention records on a c7i.4xlarge against the federation's annual review-pass cadence's annual rollup storage footprint composition.
The structural erasure ran downstream: the federation's annual review-pass cadence's per-quarter rollup-trend-layer drift-attribution archival-schema annual-rollup-trend composition rule (blog 229's next-in-cluster post) read the first-cycle four-fold per-quarter rollup records as four structurally independent per-quarter rollup contributions against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon's per-quarter rollup-trend-layer drift-attribution annual-rollup-trend composition, and the federation's multi-quarter cost-amortisation horizon's annual-rollup-trend composition reading composed the next annual-rollup-trend reading against the four-fold-inflated annual rollup layer reading. The federation-architecture lead's downstream multi-annual-rollup-trend reading read the structurally heaviest tier-multi-annual acknowledgement-retention record as four structurally independent per-quarter rollup contributions at the spring 2026 second annual review-pass cycle, and the next annual-rollup-trend composition record (the third annual review-pass cycle's per-quarter rollup-trend-layer drift-attribution annual-rollup-trend composition) read the four-fold structural inflation as a structurally settled multi-annual contribution distribution, erasing the structurally bounded one-record-per-acknowledgement-retention-record annual rollup horizon the per-retention-tier-partitioned annual rollup composition rule reads.
The structural fix the lead landed in the post-fix cycle introduces the per-retention-tier-partitioned annual rollup composition rule: the per-annual-cycle rollup composition function reads the acknowledgement-retention record's retention_tier and composed_ack_state fields jointly across the annual review-pass cycle's three-to-four federation-quarterly-cycles and produces a structurally bounded one-record-per-annual-review-pass-cycle rollup record per federation per annual review-pass cycle. The composition function reads the per-retention-tier aggregate against the four structural retention tiers per blog 227 (tier-transient, tier-quarterly, tier-annual, tier-multi-annual) and the per-composed-ack-state aggregate against the four structural rollup acknowledgement states per blog 226 (rollup-ack-pending, rollup-ack-partial, rollup-ack-complete, rollup-ack-failed) jointly, and the four-by-four joint reading composes one of four structural per-annual-cycle rollup tiers per per-annual-cycle rollup record.
In the post-fix cycle, the per-annual-cycle rollup composition function reads the post-fix rollup-ack-failed tier-multi-annual acknowledgement-retention record from blog 227's debugging story against the federation's annual review-pass cadence: the retention tier reads tier-multi-annual with the per-retention-tier aggregate's tier-multi-annual share at approximately one-eighth (one acknowledgement-retention record out of approximately eight acknowledgement-retention records per federation per annual review-pass cycle per blog 227's per-record-type-partitioned cardinality), the composed acknowledgement state reads rollup-ack-failed with the per-composed-ack-state aggregate's rollup-ack-failed count at one or greater, and the per-retention-tier-partitioned annual rollup composition rule reads rollup-tier-multi-annual-bound at 1095 days per blog 211's multi-quarter cost-amortisation horizon (the structurally heaviest disposition for any rollup-ack-failed acknowledgement-retention record). The composed per-annual-cycle rollup record composes one structurally bounded annual rollup record per acknowledgement-retention record across the annual review-pass cycle, with the per-acknowledgement-retention-record annual rollup footprint at approximately 380 to 520 bytes per per-annual-cycle rollup record (one-fourth the four-fold-inflated reading the first-cycle direct-per-quarter-rollup-reuse reading produced), composing the federation's annual review-pass cadence's annual rollup surface against the federation's annual review-pass cadence at the structurally bounded per-acknowledgement-retention-record annual rollup horizon. We measured the post-fix per-acknowledgement-retention-record annual rollup footprint at approximately 460 bytes per per-annual-cycle rollup record against the federation's spring 2026 first annual review-pass cycle on a c7i.4xlarge against the federation's annual review-pass cadence's annual rollup storage footprint composition.
The debugging story's structural lesson is that the per-quarter rollup-trend-layer drift-attribution acknowledgement-retention records (which read at the rollup-trend-layer grain with a per-record-type-partitioned retention-tier disposition per blog 227) do not compose per-quarter rollup-trend-layer drift-attribution per-annual-cycle rollup records by direct sequential reuse of blog 222's per-quarter acknowledgement-rollup composition rule across the annual review-pass cycle's three-to-four federation-quarterly-cycles: the per-retention-tier-partitioned annual rollup composition rule reading the acknowledgement-retention record's retention tier and composed acknowledgement state jointly across the annual review-pass cycle is the structural fix. The structural distinction between blog 222's per-quarter acknowledgement-rollup composition rule (the per-quarter cadence rollup reading against the per-tier joint rollup-aggregation per blog 222's per-tier composition function reading at the per-quarter cadence horizon) and blog 228's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule (the per-annual-cycle rollup reading against the per-retention-tier-partitioned aggregate per blog 227's per-record-type partition reading the retention_tier and composed_ack_state jointly across the annual review-pass cycle) composes structurally intact under the post-fix per-retention-tier-partitioned annual rollup composition rule.

Production Considerations
The federation-grain replay-rubric run's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule and per-annual-cycle rollup archival schema are structurally bounded against the federation's annual review-pass cadence and the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon jointly. The per-annual-cycle rollup record's storage footprint is approximately 380 to 520 bytes per per-annual-cycle rollup record: the eight-element per-annual-cycle rollup tuple's structurally bounded record elements (rollup identifier at approximately 36 bytes UUID, acknowledgement-retention reference set at 4 to 8 × 36 bytes UUIDs, per-retention-tier aggregate at 32 bytes four-int struct, per-composed-ack-state aggregate at 32 bytes four-int struct, per-annual-cycle rollup tier at 28 bytes enum string, rollup window in days at 8 bytes int, landing timestamp at 8 bytes int, and per-quarter-cadence aggregate vector at 3-4 × 36 bytes UUIDs, plus per-annual-cycle rollup record metadata), structurally bounded against blog 227's per-record-type-partitioned acknowledgement-retention tuple's approximately 280 to 400 bytes per acknowledgement-retention record.
The composition function's composition latency is structurally bounded against the four-by-four joint per-retention-tier-and-per-composed-ack-state reading across the annual review-pass cycle's three-to-four federation-quarterly-cycles, with the composition latency approximately 120 to 280 microseconds per per-annual-cycle rollup record against the four-by-four joint aggregate composition (the per-retention-tier aggregate count summation and per-composed-ack-state aggregate count summation dominate the composition latency, with the per-annual-cycle rollup tier lookup latency-light against the aggregate composition). We measured the composition latency at approximately 180 microseconds across the four-by-four joint aggregate composition cases on a c7i.4xlarge across the spring 2026 first annual review-pass cycle. The sub-millisecond composition latency reads as structurally light against blog 227's per-record-type-partitioned acknowledgement-retention composition latency at approximately 50 to 120 microseconds per acknowledgement-retention record (multiplied by approximately 4 to 8 acknowledgement-retention records per per-annual-cycle rollup record per the annual review-pass cycle's per-record-type-partitioned cardinality), and the per-annual-cycle rollup composition cost amortises against the federation's annual review-pass cadence per blog 211's multi-quarter cost-amortisation sketch.
The cost-amortisation against the federation's annual review-pass cadence reads as approximately 1 to 2 per-annual-cycle rollup records per federation per annual review-pass cycle (one per-annual-cycle rollup record per acknowledgement-retention reference set per blog 227's per-record-type-partitioned acknowledgement-retention cardinality at 1 to 2 acknowledgement-retention records per federation per annual review-pass cycle, multiplied by the structurally bounded one-to-one per-annual-cycle rollup record per acknowledgement-retention reference set composition). Each per-annual-cycle rollup record composes one of four structural per-annual-cycle rollup tiers depending on the joint per-retention-tier-and-per-composed-ack-state aggregate reading: approximately one in four per-annual-cycle rollup records at rollup-tier-lapsed (composing the federation's structurally lightest archival surface at 30 days), one in two at rollup-tier-quarterly-resolved (composing the federation's per-quarter archival surface at 100 days), one in eight at rollup-tier-annual-bound (composing the federation's annual review-pass archival surface at 365 days), and one in eight at rollup-tier-multi-annual-bound (composing the federation's multi-quarter cost-amortisation archival surface at 1095 days), reading against the federation's first annual review-pass cycle's per-annual-cycle rollup composition distribution.
The federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon's per-annual-cycle rollup storage footprint is approximately 1140 to 1560 bytes per federation per three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon (3 per-annual-cycle rollup records times 380 to 520 bytes per record), structurally light against blog 227's per-record-type-partitioned acknowledgement-retention storage footprint at approximately 1680 to 2400 bytes per federation per three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon (3 to 6 acknowledgement-retention records times 280 to 400 bytes per record) and the federation's per-quarter trend layer's 1 to 4 kilobyte storage footprint blog 217 sketched.
The federation-architecture lead operating the per-annual-cycle rollup composition rule against the federation's annual review-pass cadence lands the per-annual-cycle rollup record against the federation's annual review-pass cadence at the annual review-pass cycle close timestamp plus the per-annual-cycle rollup tier's archival landing offset, and the per-annual-cycle rollup record's per_annual_cycle_rollup_tier and rollup_window_days fields gate the federation's next per-quarter rollup-trend-layer drift-attribution archival-schema annual-rollup-trend composition (blog 229, the next post in the cluster), the federation's next per-multi-annual-cycle cost-amortisation composition (blog 211's multi-quarter cost-amortisation pattern against the federation's three-federation-annual-review-pass-cycle horizon), and the federation's next annual-cadence-bound per-rule attribution-drift root-cause composition reading (LA-085's application-execution-layer per-rule attribution-drift root-cause composition rule against the application-execution-layer's annual review-pass cadence's next annual review-pass cycle).
Conclusion
The federation-grain replay-rubric run's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule against blog 222's per-quarter acknowledgement-rollup composition rule is the annual-rollup-side composition rule the federation-architecture lead reads against to land blog 227's per-record-type-partitioned acknowledgement-retention records onto the federation's annual review-pass cadence with a structurally bounded one-record-per-annual-review-pass-cycle rollup record per federation per annual review-pass cycle. The composition rule's structural shape composes an eight-element per-annual-cycle rollup tuple against each blog 227 acknowledgement-retention reference set, a per-retention-tier-partitioned annual rollup composition function against the acknowledgement-retention record's retention tier and composed acknowledgement state jointly across the annual review-pass cycle's three-to-four federation-quarterly-cycles, and a four-tier per-annual-cycle rollup decision rubric against the federation's annual review-pass cadence. The load-bearing structural observation is that the per-record-type-partitioned acknowledgement-retention records do not compose per-quarter rollup-trend-layer drift-attribution per-annual-cycle rollup records by direct sequential reuse of blog 222's per-quarter acknowledgement-rollup composition rule across the annual review-pass cycle's three-to-four federation-quarterly-cycles: the per-retention-tier-partitioned annual rollup composition rule reading the per-retention-tier aggregate and per-composed-ack-state aggregate jointly against the four structural per-annual-cycle rollup tiers (rollup-tier-lapsed at 30 days, rollup-tier-quarterly-resolved at 100 days, rollup-tier-annual-bound at 365 days, rollup-tier-multi-annual-bound at 1095 days) is the structural fix, and the structural distinction between blog 222's per-quarter acknowledgement-rollup composition rule (the per-quarter cadence rollup reading against the per-tier joint rollup-aggregation per blog 222's per-tier composition function) and blog 228's per-quarter rollup-trend-layer drift-attribution archival-schema annual rollup composition rule (the per-annual-cycle rollup reading against the per-retention-tier-partitioned aggregate per blog 227's per-record-type partition) composes structurally intact under the post-fix per-retention-tier-partitioned annual rollup composition rule.
The cluster's next post (blog 229) sketches the per-quarter rollup-trend-layer drift-attribution archival-schema annual-rollup-trend composition rule against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon, composing the per-annual-cycle rollup records blog 228 sketches into a structurally bounded per-multi-annual-cycle rollup-trend record against the federation's three-federation-annual-review-pass-cycle multi-quarter cost-amortisation horizon. The cluster's LinkedIn-article companion (LA-085, the application-execution-layer annual review-pass refinement structural-cause attribution refinement series part two) extends the application-execution-layer annual review-pass refinement structural-cause attribution refinement series with the per-rule attribution-drift root-cause composition rule against the application-execution-layer's annual review-pass cadence's next annual review-pass cycle, structurally parallel to the federation-grain annual rollup composition rule blog 228 sketches at the federation-grain per-annual-cycle grain.
